Pulsed Gliding Arc Electrical Discharge Reactors Dr. Bruce Locke 06-142 Garrett Edmunds Gedmunds@fsu.edu <p>Gliding arc discharges have been investigated as a potential technology for gas phase pollution treatment and for liquid phase pollution treatment. Ultimately, the practical use of gliding arc technology to promote chemical transformations, such as the removal of organic pollutants in water or the generation of hydrogen peroxide, other reactive oxygen species, or reactive nitrogen species for treatment of potentially contaminated foods, depends on the efficiency that can be achieved.</p> <p>The present invention describes a plasma gliding arc discharge reactor that is useful for chemical transformations in liquids and gases. The reactor may include a housing having a plurality of divergent electrodes, a power supply connected to the electrodes delivering pulsed power to the reactor, and a nozzle that directs a mixture of a carrier gas and a liquid to a region between the divergent electrodes, thereby generating plasma in the region. The nozzle can include a first inlet for receiving the carrier gas, a second inlet for receiving the liquid and a mixing chamber that is configured to mix the carrier gas and the liquid prior to being directed to the region.</p>

MultiSense: A Highly Reliable Wearable-Free Fall Detection System Dr. Zhenghao Zhang 18-015 Michael Tentnowski mtentnowski@fsu.edu <p class="lead"><span class="small">Professor Zhang and his team have developed A reliable fall detection system has tremendous value to the well-being of seniors living alone. We design and implement MultiSense, a novel fall detection system, which has the following desirable features. First, it does not require the human to wear any device, therefore convenient to seniors. Second, it has been tested in typical settings including living rooms and bathrooms, and has shown very good accuracy. Third, it is built with inexpensive components, with expected hardware cost around $150 to cover a typical room. Therefore, it has a key advantage over the current commercial fall detection systems which all require the human to wear some device, as well as over academic research prototypes which have various limitations such as lower accuracy. The high accuracy is achieved mainly by combining senses from multiple types of sensors that complement each other, which includes a motion sensor, a heat sensor, and a floor vibration sensor. Roughly speaking, the activities confusing to some sensors are often not confusing to others, and vice versa; therefore, combining multiple types of sensors can bring the performance to a level that can meet the requirements in practice.</span></p>
Drugs for the Treatment of Zika Virus Infections Hengli Tang 16-114 Brent Edington bedington@fsu.edu <p>The Zika virus is a Flavivirus that is spread to humans through mosquito bites. It is presently a major human health concern. When pregnant women are infected the virus can be transferred to the baby and result in microcephaly and other sever brain problems. Infections can also result in Guillain-Barre syndrome in adults and children, a neurological syndrome that can cause temporary paralysis. There are presently no vaccines or medications capable of preventing or treating Zika virus infections.</p> <p>Various libraries of known compounds have been screened for their ability to inhibit Zika virus infections. A collection of compounds has been identified which have activity against Zikda virus replication and growth. These compounds have been assessed and ranked according to efficacy in test assays and suitability as therapeutic compounds.</p>
Organic Chemical Synthesis using Plasma Reactors with Liquid Organic and Liquid Water Bruce Locke 13-153 Garrett Edmunds gedmunds@fsu.edu <p>Electrical discharge plasma contacting liquid phases has been studied for a wide range of chemical, biomedical, environmental, and Materials synthesis applications.  The present invention utilizes a gas-water-organic plasma reactor for the conversion of alkanes into functionalized products (alcohols, aldehydes, etc.) using a pulsed plasma reactor with liquid water and flowing carrier gas. Hydrogen peroxide is also generated conjunction with the functionalized products.</p> <h1>Applications</h1> <ul> <li>Agriculture</li> <li>Healthcare</li> <li>Sanitization</li> <li>Waste water degradation</li> </ul>
Repurposed Use of the Alkaloids Emetine and Cephaeline to Treat Zika Virus Infection Hengli Tang 18-017 Brent Edingtn bedington@fsu.edu <p>Zika virus (ZIKV), a mosquito-borne flavivirus, has re-emerged and spread across the Western Hemisphere in the past year. A large outbreak started in Brazil in late 2014 and is a growing public health concern. Currently, active transmission has been reported in 58 countries and territories globally. About 20% of ZIKV infected individuals develop symptoms, which mostly resemble symptoms caused by other arboviruses, such as dengue viruses or chikungunya virus. Unlike these viruses, however, ZIKV causes congenital defects, including microcephaly, and is also associated with Guillain-Barré syndrome in infected adults.</p> <p> </p> <p>The present invention concerns the novel use of emetine compounds for the treatment or prevention of Flavivirus infections, such as Zika virus infections. Emetine compounds have been FDA approved for use against amoebiasis and has been shown to have some anti-viral activity against other viruses.</p> <p> </p>
Comprehensive, Genome-Wide Epigenetic Fingerprinting by Replication Profiling David Gilbert 07-106 Brent Edington bedington@fsu.edu <p>This is a procedure for typing cells (cancer cells, stem cells, any kind of cells) based upon the order of replication of chromosome segments. In brief, cells from any source are pulse-labeled with 5-bromo-2deoxyuridine, sorted into early and late S-phase of the cell cycle by flow cytometry and the DNA replicated in each temporal compartment of S-phase is differentially labeled and hybridized to a DNA array consisting of evenly spaced probes from the entire genome. Using customized algorithms, the resulting data (ratio of each probe sequence replicated in early vs. late S-phase) can be converted into a form that can segment the genome and identify the order of replication of chromosome segments characteristic for a cell type. An alternative, if the cell line is difficult to label metabolically, is to sort cells into S-phase and G1-phase populations, hybridize differential labeled DNA from these sorted populations, and determine the ratio of each probe sequence in S vs G1. This provides similar data that can be evaluated by the same computational conversion.</p> <h2>Advantages:</h2> <ul> <li>More comprehensive (covers the entire genome)</li> <li>Less expensive (covers the entire genome for less than 1/20th what is needed for existing profiling methods)</li> <li>Much easier to interpret- the informative data for each cell line is distilled down to combinations of only about 1,000-2,000 segments of the genome that uniformly identify each cell type</li> <li>Measures very different properties of cells than any other method</li> <li>Focuses the analysis on the proliferating population of cells, which is particularly useful for stem cell and cancer technologies.</li> </ul>
A Peptide Building Block for P-trefoil Protein Architecture Dr. Blaber 10-114 Brent Edington bedington@fsu.edu <p>Protein folding is a poorly understood science, and therefore, protein engineering has yet to realize the functional potential inherent in proteins. Development of a useful "structural toolkit" for de novo protein design is a highly desirable, yet unrealized goal of the field.</p> <p>A novel 42 amino acid polypeptide sequence has been designed that spontaneously assembles into a homo-trimer, forming a thermostable P-trefoil protein architecture. The polypeptide can also be ligated, to form three identical repeating sequences within a single polypeptide, which also spontaneously folds into a thermostable P-trefoil protein architecture. The peptide is thus useful for either de novo design, rational design, or directed evolution of novel proteins based upon the P-trefoil architecture. The Invention represents an initial successful example of the development of a useful peptide building block for a common protein architecture (the P-trefoil).</p> <p>The peptide sequence was designed using a novel approach, and as a consequence there are an extremely limited number of useful related "building blocks" in protein design. The idea of a "structural toolkit" for protein design is largely conceptual; the current Invention is arguably one of the first successful examples.</p>
Selective Dopamine D4 Receptor Agonists for the Treatment of Working Memory Deficits Pradeep G. Bhide 14-038 Brent Edington bedington@fsu.edu <p>Dopamine is a critical regulator of working memory, a mechanism for short-term information storage. Deficits in working memory occur in diseases with dopamine imbalance such as ADHD, schizophrenia and Parkinson’s Disease. However, a targeted treatment for working memory deficits is not available. In rodent models with working memory deficits, we show that selective activation of the dopamine D4 receptor (D4R) improves working memory. Based on these findings we propose that drugs that selectively activate the D4 receptor are novel class drugs for the treatment for working memory deficits.</p> <p>D4R is found in abundance in the frontal cortex and hippocampus, brain regions that regulate working memory function. We examined two rodent models with working memory deficits, a prenatal nicotine exposure mouse model and the spontaneously hypertensive rat model. In both the models, activity and expression of the D4R are significantly decreased in the frontal cortex. Although dopamine D2 receptors expression and activity are also decreased in the frontal cortex of these models, improvements in working memory produced by psycho-stimulant administration were accompanied by increases in the activity of only the D4R and not the D2 receptor. Therefore, it can be concluded that selective increase in frontal cortical D4R activity is associated with improvement of deficient working memory.</p> <p>Dopaminergic drugs that activate or antagonize multiple dopaminergic receptors or that produce global increases in brain dopamine content have failed as effective treatments for working memory deficits because of their pleotropic actions. Our discovery suggests that drugs that selectively target the D4 receptor and improve its function are effective treatments for working memory deficits.</p>
TrkB Receptor Antagonist for Treatment of Cognitive Inflexibility Pradeep G. Bhide 15-137 Brent Edington bedington@fsu.edu <p>Cognitive flexibility is the ability to execute multiple mental tasks simultaneously, to switch from one task to the next easily, and to restructure knowledge and strategy to tackle changing tasks. Deficits in cognitive flexibility are associated with multiple psychiatric conditions including schizophrenia, autism spectrum disorder and ADHD. Despite its critical role in normal mental function, and despite its well documented associated impairment, drugs that selectively target and improve cognitive flexibility are not available.</p> <p>The present technology shows that excess brain derived growth factor (BDGF) is associated with deficits in cognitive flexibility and that ANA-12 is an effective treatment for cognitive ability.</p>
Monoclonal Antibodies Specific for 4,6-Diamino-5-(Formylamino) Pyrimidine Gary Ostrander and Eric Holmes 16-019/ 18-016 Brent Edington bedington@fsu.edu <p>The present invention describes monoclonal antibodies that are specific for 4,6-Diamino-5-(formylamino)pyrimidine. This structure, also known as FAPY-A, is formed in DNA bases by single electron oxidation reactions caused primarily by oxygen free radicals. Damage to DNA of this sort, along with its alternate product 8-hytdroxy-pyrimidine derivatives, can result in mutations from misreading if not first repaired. In the case of free radical oxidations of the DNA base Adenine, FAPY-A and 8-OH-A formed under more oxidative redox conditions. These different reaction products and their expression in biological tissues seems to correlate well with precancerous and cancerous changes in tissues. Thus, detection of FAPY-A and 8-OH-A via immunoassay may provide important future cancer risk information to individuals. Detection of FAPY-A in populations of various species can also act as an indicator of environmental damage.  </p>
Fusicoccane Derivatives and Methods Prof. James Frederich 17-039 Garrett Edmunds gedmunds@fsu.edu <p>Fusicoccanes are a family of natural products containing a characteristic 5-8-5 carbocyclic nucleus. Certain of these natural products, namely fusicoccin (FC) and cotylenin (CN), have attracted considerable interest for their anticancer activity. These molecules cooperate with the cytokine interferon-alpha to induce apoptosis in cancer cells with negligible toxicity to healthy cells.</p> <p>Professor Frederich and his team have developed a short and flexible photochemical process to prepare the core of these diterpenes and a range of non-natural variants. This synthetic chemistry provides direct access to functional structures with valuable applications in biomedical research and drug development.</p> <p>In the news:</p> <p><a href="https://www.chemistryworld.com/news/four-step-route-to-carbotricycles/3009180.article">https://www.chemistryworld.com/news/four-step-route-to-carbotricycles/3009180.article</a></p> <p><span><a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__app.meltwater.com_mwTransition_-3Furl-3Dhttps-253A-252F-252Fwww.sciencedaily.com-252Freleases-252F2018-252F07-252F180703143810.htm-26uId-3D56547ed34c07ddc0670b7c8f-26cId-3D55f84f24ab7e72fa1a4861aa-26dId-3DmaVnLQrhuPt1NOfjrR9BF-5FfEgpo-26contextId-3D5b3dfda3050a7ecb4ce1448b-26op-3Dopen-26sentiment-3DN-26isHosted-3Dfalse-26publishTime-3D1530653142450-26id-3D-26name-3D-26type-3D-26transitionToken-3DeyJ0eXAiOiJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJob3N0bmFtZSI6Ind3dy5zY2llbmNlZGFpbHkuY29tIn0.Ki-5FMhVIfMfUk7falEvFecn0pLyO2IbwTRz0pkC5PQ1uOxwTzEl1gaKsfWOGSIrAp9s-5FbATcjZQWi29WHH6Kuzg-26s-3Dmail-2Dnewsletter&amp;d=DwMFaQ&amp;c=HPMtquzZjKY31rtkyGRFnQ&amp;r=WPBE5mf0vyLaRUqjuwH1sg&amp;m=gds5bbavh_mOdw_HPOAn-28dTWw1TVDSjNLAhAIdhfg&amp;s=YwFs1A7P4BnsXk0ndHmTkrtzEkJGOnu34P3vz9tJhDg&amp;e=">Breakthrough synthesis strategy could mean a wave of new medicinal compounds</a></span></p> <p><span><a href="https://urldefense.proofpoint.com/v2/url?u=https-3A__app.meltwater.com_mwTransition_-3Furl-3Dhttps-253A-252F-252Fwww.news-2Dmedical.net-252Fnews-252F20180704-252FInnovative-2Dsynthetic-2Dtechnique-2Dopens-2Ddoor-2Dto-2Dnew-2Dworld-2Dof-2Dcutting-2Dedge-2Dmedicinal-2Dcompounds.aspx-26uId-3D56547ed34c07ddc0670b7c8f-26cId-3D55f84f24ab7e72fa1a4861aa-26dId-3Dgj8XzuoC5zJ0WF3if4FF53pkkc0-26contextId-3D5b3dfda3050a7ecb4ce1448b-26op-3Dopen-26sentiment-3DN-26isHosted-3Dfalse-26publishTime-3D1530640920639-26id-3D-26name-3D-26type-3D-26transitionToken-3DeyJ0eXAiOiJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJob3N0bmFtZSI6Ind3dy5uZXdzLW1lZGljYWwubmV0In0.rU0GULKC-5F2ZAVA6OU89-2DA2RYgAPyGPGO2xWgL4m-2Dsmlcv-5Fz0gkYGgmtgFPcp5l-2Dzw5agpVVczbF7idNkIMwIsA-26s-3Dmail-2Dnewsletter&amp;d=DwMFaQ&amp;c=HPMtquzZjKY31rtkyGRFnQ&amp;r=WPBE5mf0vyLaRUqjuwH1sg&amp;m=gds5bbavh_mOdw_HPOAn-28dTWw1TVDSjNLAhAIdhfg&amp;s=wihplsHAdfgWkE8eGtsvfmv-mG2oqhmU0B6p4xbHTlQ&amp;e=">Innovative synthetic technique opens door to a new world of cutting-edge medicinal compounds</a></span></p> <p> </p>
Tumor Drug Resistance Measured by Sodium Diffusion Dr. Schepkin 12-106 Michael Tentnowski mtentnowski@fsu.edu <p>This invention is a non-invasive, comprehensive and individualized evaluation of tumor resistance using sodium and/or diffusion magnetic resonance imaging (MRI). The method includes conducting a sodium and/or diffusion MRI on a tumor of a subject and on a normal region of the subject- for example, the normal region in brain being contralateral to the tumor. When the images of the MRI procedures have been obtained, the indicias (i.e., sodium and/or diffusion) are measured and analyzed. These indicias are compared between the tumor region and normal region. A low level of the indicia in the tumor region, relative to the level of indicia in the normal region, indicates a higher/increased tumor resistance to a drug.</p> <p>Currently, a biopsy and Positron emission tomography (PET) are the conventional technologies used to deliver information on tumor resistance prior to therapy. The evaluation can be performed prior to therapy and can help select a strategy of treatment but also help in evaluating the efficacy of an agent for the treatment of cancer in a subject. The invention can be used in the brain glioma model but is contemplated for use in different types of tumors in most parts of the human body in addition the agent may be carmustine, though other tumor types and agents are contemplated by the invention. The level of tumor resistance can be determined reproducibly in a relatively short amount of time, for example less than thirty minutes, and the results can be used immediately to create individualized therapy.</p> <p>The invention allows clinicians to avoid ineffective therapies, which may be more harmful than useful or come up with the other more appropriate alternatives. It can facilitate a separation of the effects due to metabolic changes in the tumor at the beginning of therapy from the effects introduced by drug intervention.</p>
Thiol-ene polymer metal oxide nanoparticle high refractive index composites Dr. Albert Stiegman 12-228 Garrett Edmunds gedmunds@fsu.edu <p>For optical applications in general and eyewear in particular, the synthesis of new polymers with refractive indices &gt;1.65 and acceptable Abbe numbers is of considerable importance. Higher refractive index materials will permit smaller, lighter weight lenses to be used and provide a much broader graded index for progressive lenses. The material modification that leads to higher refractive indices is the incorporation of highly polarizable atoms and ions. Incorporating such polarizable groups has been the standard protocol used to develop new high R.I. polymers. The electronic polarizability is a tensor property of an atom or molecule that measures the distortion of the electron cloud in the presence of an applied electric field (which can be an optical field). The more the electron cloud can be distorted, the higher the refractive index. The characteristics of atomic and molecular electronic structure that yield large polarizabilities are well understood and can be predicted from basic chemical principles. In particular, the more electronegative an atom is the less polarizable it will be, hence late first-row elements such as F, O and N tend to yield lower refractive index materials. Better choices are 2<sup class="style-scope patent-text">nd</sup>, 3<sup class="style-scope patent-text">rd </sup>or 4<sup class="style-scope patent-text">th </sup>row main group elements such as S (which is currently used in order to increase the refractive index in many polymeric materials), P, and Sn. From a molecular standpoint, the higher electronegativity of the first row can be overcome by delocalization of the electrons across several atoms. Aromatics are more polarizable than saturated hydrocarbons and compounds such as propylene carbonate and dimethylformamide have high dielectric constants.</p> <p>the present invention comprises a bulk polymer composite comprising a thiol-ene polymer matrix, or a matrix comprising a corresponding polymer derived from a phosphinyl, selenol, or arsinyl monomer, and metal oxide nanoparticles dispersed within the matrix, said nanoparticles being bonded to polymer molecules contained in the matrix. In certain preferred embodiments, the polymer matrix comprises a matrix corresponding to the structure.</p>
D-Serine as a Modulator of Epileptic Seizures, Seizures, and Neurological Disorders Sanjay Kumar 13-144 Brent Edington bedington@fsu.edu <p>Researchers at Florida State University Medical School have determined that D-serine can be used to modulate the onset and severity of seizures resulting from epilepsy or other neurological disorders.</p> <p> </p> <p>Dr. Kumar and his associates have recently discovered that certain brain cells express receptors to which D-serine is an antagonist. D-serine essentially shuts off the ion channels that these receptors regulate. Because these receptors are located in regions of the brain associated with neurological disorders such as seizures and epilepsy, D-serine may be used to treat such neurological disorders. D-serine can be used to modulate the regulation of ion channels and prevent the onset of and severity of seizures. This technology involves artificially administering a composition of D-serine to select regions of a patient’s brain having epilepsy or other neurological disorders causing seizures and reducing the severity or onset of seizures.</p> Epilepsy,Seizures,Neurological Disorders
Microfluidic Sample Preparation Device for Electron Microscopy Dr. Michael Roper and Dr. Scott Stagg 15-230 Garrett Edmunds gedmunds@fsu.edu <p>Cryogenic electron microscopy (cryoEM) is quickly becoming a routine method in the determination of high-resolution structures of biological molecules. However, for most samples before cryoEM data can be collected, the sample quality and heterogeneity must first be characterized using negative staining. Conventionally, EM grids are prepared by hand and, as such, variability is introduced due to user-to-user differences. The variability of the staining can have large effects on the final stained sample, ultimately hindering the resolution, image processing, and data analysis.</p> <p>A microfluidic platform is presented for preparing negatively stained grids for use in transmission electron microscopy (EM). The microfluidic device is composed of glass etched with readily fabricated features that facilitate the extraction of the grid post staining and maintains the integrity of the sample. The device allows for sealing of an electron microscopy grid, facile and reproducible delivery of a sample, followed by delivery of subsequent solutions that could be negative stains or other biological samples. The device houses the EM grid in an outlined chamber with an access point below the grid for gentle and easy recovery of the EM grid. The fluid is directed to the grid using the integrated channels of the microfluidic system.</p> <p>Utilization of this device simultaneously reduced environmental contamination on the grids and improved the homogeneity of the heavy metal stain needed to enhance visualization of biological specimens as compared to conventionally prepared EM grids.</p> <p>High-magnification images from grids prepared by the microfluidic system showed similar image qualities as those prepared by hand. With this methodology for housing the grid, opportunities are abound for more integrated systems using elastomeric materials for incorporation of valving and other microfluidic features. For example, this system can subsequently be complemented with gradient generators or multianalyte perfusion and reaction timers to study both multivariable interactions as well as reaction kinetics. This proof</p> <p>of principle paves the way for future added layers of complexity that can be used to uniquely investigate structural biology dynamics.</p> <h2>Advantages:</h2> <ul> <li>User friendly</li> <li>Reproducibility</li> <li>Parallel/high throughput</li> <li>Results have been published in Analytical Chemistry (Roper, 2016, American Chemical Society Publications) and led to multiple requests by research groups offering to beta test the prototype.</li> <li>Straightforward manufacturing</li> </ul> <p>For further reading, please visit:</p> <p><a href="http://www.roperlab.com/"><strong>http://www.roperlab.com/</strong></a><strong> <br /></strong></p> <p><a href="http://pubs.acs.org/doi/abs/10.1021/acs.analchem.5b03884"><strong>http://pubs.acs.org/doi/abs/10.1021/acs.analchem.5b03884</strong></a></p> <p><video alt="" width="400" controls="controls"> <source src="/media/4180/rs4-fin.mp4" type="video/mp4" /> Your browser does not support HTML5 video. </video></p>
Central Executive Training for ADHD Dr. Michael Kofler 16-106 Michael Tentnowski mtentnowski@fsu.edu <p>Attention-deficit/hyperactivity disorder (ADHD) is a complex, chronic, and potentially debilitating disorder of brain, behavior, and development that affects approximately 5.4% of school-aged children at an annual U.S. cost of illness of over $42 billion. Medication and behavioral treatment are effective for reducing symptoms, but they are considered maintenance therapies because their benefits disappear within minutes to hours after treatment is stopped. Clearly, novel treatments are needed.</p> <p> </p> <p>Central Executive Training (CET) is a novel, evidence-informed, computerized training protocol developed based on recent advancements in clinical and neuropsychological science. It differs fundamentally from existing, capacity-based “working memory training” programs. Each of CET’s 9 training games implement advanced algorithms to adapt based on the child’s performance and build capabilities across three, empirically-identified functions of the midlateral prefrontal cortex. These 3 functions involve dual-processing, continuous updating, and temporal ordering, and are collectively known as the brain’s ‘central executive.’</p> <p> </p> <p>Central executive abilities are targeted in CET based on fMRI evidence of significant cortical underdevelopment in these areas in children with ADHD. Importantly, our previous work has shown that hyperactivity and inattentive symptoms are most pronounced in children with ADHD when they are engaged in activities that challenge their underdeveloped central executive abilities. In fact, several studies have found that children with ADHD do not show attention deficits or hyperactivity during conditions with minimal central executive demands.</p> <p> </p> <p>Our preliminary data show that CET is superior to the current gold standard psychosocial treatment (behavioral parent training) for improving working memory in children with ADHD. Our data also show that CET is superior to the gold standard for reducing hyperactivity symptoms measured using high-precision actigraphs that sample children’s movement 16 times per second. CET was equivalent to the current gold standard for reducing ADHD symptoms based on parent report. A randomized clinical trial of CET is underway.</p> <p> </p> <p><a rel="noopener noreferrer" href="http://news.fsu.edu/news/science-technology/2018/01/24/fsu-psychologist-receives-2m-nih-grant-test-nonmedication-treatment-adhd/" target="_blank" title="http://news.fsu.edu/news/science-technology/2018/01/24/fsu-psychologist-receives-2m-nih-grant-test-nonmedication-treatment-adhd/">More on the NIH Award and a radio interview of Dr. Kofler.</a></p> <p> </p> ADHD
Frequency-Modulated Continuous Flow Analysis Dr. Michael Roper 18-002 Garrett Edmunds gedmunds@fsu.edu <p>Professor Roper and collaborators have developped a new method to multiplex mass spectrometric sample analysis. The purpose of this invention is to be able to analyze multiple samples simultaneously using mass spectrometry. The operation of this method is to pulse the flow of individual samples to the mass spectrometer at unique frequencies. The flow from the individual samples are combined together with a make-up flow that is used to ensure the total flow rate to the mass spectrometer is constant. After mixing of all the streams from the samples and the make-up flow, pulses of each sample are delivered to the mass spectrometer with the pulse frequencies being unique to that particular sample. The mass spectrometer collects the m/z data vs. time. At each m/z there is a time-dependent signal that is the sum of all the pulses from the different samples. For any one particular m/z, a Fourier transform is used to convert the time-based mass spectrometry signal intensity to the frequency domain resulting in a series of peaks at particular frequencies. Each of these frequency peaks corresponding to the different samples. The height of the peaks in the frequency domain is proportional to the concentrations of the samples in the syringes.</p> <p>The benefit of this new method over the labeling strategy is that the frequency modulated approach allows multiplexing of a theoretically wide number of samples without the need for chemical labeling. Therefore, any problems with chemical labeling (inefficiencies, side products, etc.) are avoided. Also, more than 4-5 samples can be used simultaneously as Jong as their frequencies can be resolved in the frequency domain and the analytes are within the dynamic range of the mass spectrometer. A final advantage is that since all the samples are combined together, any samples that may have different levels of salts (detrimental to mass spectrometry) experience the same salt concentration. This means that they are all affected in the same manner and are much less susceptible to salt effects which hurt mass spectrometry experiments.</p> <p>This technology was developed in collaboration with Jim Edwards at Saint Louis University</p>
Mutations of the Rhodopsin Gene in Zebrafish and uses of the Mutations James Fadool 17-038 Brent Edington bedington@fsu.edu <p>The invention involves isolation and use of zebrafish having novel genetic mutations in the rhodopsin genes dealing with retinal disease to serve as a model for human retinal disease. Rhodopsin is a protein receptor expressed in the light sensitive cells of the retina responsible for initiation of vision. Nearly 100 spontaneous mutations in the human rhodopsin genes are associated with inherited photoreceptor degeneration, retinitis pigmentosa, progressive retinal degeneration, low vision and blindness for which there are currently no cures. The novel zebrafish models were generated to produce known disease causing mutations in the zebrafish rhodopsin genes. DNA sequencing revealed the novelty of the isolated zebrafish mutations. Analysis of the retinal phenotypes associated with the novel alleles of zebrafish rhodopsin genes revealed that specific mutations were associated with phenotypes that mimic photoreceptor defects and degeneration observed in humans. These zebrafish models provide novel tools for investigating the cellular consequences of expression of mutated forms of rhodopsin, and are useful for genetic, small molecule, and chemical screens, or molecular manipulations with the goal of discovering compounds, genes, or treatments that may alter, slow, reverse or prevent the photoreceptor defects.  </p>
Dorsiflexion Splinting for Treatment of Peripheral Artery Disease Judy Delp 18-013/ 20-008 Brent Edington bedington@fsu.edu <p>Patients with peripheral arterial disease (PAD) often have walking impairment and pain during walking due to insufficient oxygen supply to the leg muscles. Existing clinical treatment of PAD involves walking programs or revascularization. Surgery can carry significant costs and risks of acute complications from, for instance, recurrences due to restenosis or graft occlusion. Adherence to long-term walking programs can be difficult and painful for frail patients such as the elderly. Although, stretching of calf muscles improves vascular function in the lower leg and walking is the best therapy. Use of a splint developed by researchers at Florida State University can enhance a patient’s vascular function by improving blood flow to the leg and decrease in pain during walking. The splint positions the leg and stretches muscles in a way that improves blood flow and/or oxygenation while resting. This device will be automated to easily adjust to the correct position for optimum therapeutic value for each patient.</p> <p> </p> <p>The splint allow the patient to walk without a high level of pain and thus able to walk as a useful therapy.</p>
Personalized immunotherapy selection for breast cancer Professor Qing-Xiang Amy Sang and Professor Jinfeng Zhang 17-046 Garrett Edmunds gedmunds@fsu.edu <p>Professors Sang and Zhang  have identified biomarkers that define subgroups of breast cancer and clinically useful classifiers for distinguishing breast cancer subtypes.  The present invention provides methods for selecting a therapy for a patient suffering from breast cancer based on expression levels of biomarkers.  The present invention also provides methods for treating breast cancer. </p>
CHIMERIC HUMAN PROTEINS AND THEIR USE IN IDENTIFYING NOVEL ANTI-DEUBIQUITINASE COMPOUNDS Robert Tomko 18-005 Brent Edington bedington@fsu.edu <p>This technology involves chimeric proteins having deubiquitinase activity and methods of identifying anti-deubiquitinase compounds using the chimeric proteins. These methods and assays can be adapted to high throughput screening procedures to assay for anti-cancer drugs effecting deubiquitinase activity. Disrupting the Rpn11 deubiquitinase function is a validated strategy for treatment of human cancers.</p> <p>The assay utilizes a collection of genetically modified yeast strains producing a chimeric human proteasomal Rpn11 deubiquitinase. In baker’s yeast, deletion of the endogenous yeast Rpn11 gene is lethal, but inhibition of Rpn11 deubiquitinating activity is not. Inhibition of Rpn11 activity is lethal only when a second deubiquitinase, UBP6 (USP14 in humans), is deleted. Importantly, this synthetic lethal relationship is maintained in yeast harboring hRpn11. Thus, a selective inhibitor of human Rpn11 would be lethal in the hRpn11 strain lacking UBP6, but nontoxic in a strain containing UBP6 and harboring inactivating point mutations in hRpn11.By measuring cell growth in the presence of potential inhibitors using any commercially available plate reader, a high throughput cell-based screen for compounds selectively inhibiting hRpn11 can be enacted.</p>
Polyethylene Glycol Based Oligomers for Coating Nanoparticles Dr. Hedi Mattoussi 12-026 Garrett Edmunds gedmunds@fsu.edu <p id="p-0013" class="style-scope patent-text">We have developed nanoparticle coatings that are water dispersible, have a strong affinity for binding to magnetic nanoparticles, and can be easily modified for attaching the coating to biological materials. The nanoparticle coatings comprise a polyacrylic acid based backbone onto which PEG-based oligomers are appended by modifying the native carboxyl groups of the PAA backbone. The PEG-based oligomers include functional groups on their terminal ends, which are chosen to provide a certain function. Some of the terminal functional groups bind the coatings to the nanoparticle's surface, while others provide reactive sites for binding other compounds to the coating. The method we developed for making these coatings allows one to tune the number and type of PEG-based oligomers appended to the PAA backbone based on the desired properties of the coating.</p> <p id="p-0014" class="style-scope patent-text">In accordance with a composition aspect of the invention, the nanoparticle coatings comprise repeating polyacrylic acid monomers covalently bound together in an aliphatic chain having a plurality of carboxylic acid functional groups and modified carboxylic acid functional groups extending there from. A first portion of the modified carboxylic acid functional groups are modified by a PEG oligomer having a terminal methoxy functional group and a second portion of the modified carboxylic acid functional groups are modified by a PEG oligomer having at least one terminal catechol group.</p>
Modified Fibroblast Growth Factor 1 (FGF-1) Polypeptides with Increased Binding Affinity for Heparin and Associated Methods Michael Blaber 15-039 Brent Edington bedington@fsu.edu <p>A Mutant FGF-1 was designed so as to increase the intrinsic affinity for heparin sulfate glycosaminoglycan; involving a point mutation that introduces a basic amino acid (i.e. Arg or Lys) at position Ser116. Characterization of this mutant (S116R) shows reduction in mitogenic stimulation, increase in growth factor receptor-1c activation, and prolonged duration of glucose lowering in hyperglycemic mice. Such a mutant form can be advantageous in reducing blood glucose and as a novel insulin sensitizer to treat metabolic disorder.   </p>
Reusable Colorimetric Fluoride Sensors Dr. Sourav Saha 10-186 Garrett Edmunds gedmunds@fsu.edu <p>Fluoridation of drinking water has been effective in preventing tooth decay and improving overall den-tal health; however, overexposure to fluoride poses numerous serious health risks including brittle bone disease and increases in bone cancers. Thus, accurate detection of fluoride levels in water and food sources as well as in body fluids is essential. </p> <p><a rel="noopener" data-id="7056" href="/media/4156/marketing-document-10-186-saha.pdf" target="_blank" title="Marketing document 10-186 Saha.pdf">Download PDF Version</a> </p> <h2>Applications:</h2> <ul> <li>Medicine and health applications, both commercial and consumer-oriented, to test for the presence of fluoride in tap water, foods, blood and urine</li> <li>Food industry applications, such as testing toothpaste, bottled water, and food products</li> <li>Commercial product to enable water purifier manufacturers to test the effectiveness of their products more easily and at a reduced cost</li> <li>Municipal water-testing applications, particularly field testing</li> <li>Humanitarian application for use in developing countries with few or non-existent fluoride testing tools or standards</li> </ul> <h2>Advantages:</h2> <ul> <li>Offers both colorimetric and fluorimetric detection</li> <li>Can detect fluoride presence and quantity in a variety of environments including water, food, gas/air, and body fluids</li> <li>The sensors are easy to synthesize, environmentally benign, and can detect a range of fluoride concentration levels, with high sensitivity at extremely low nanomolar concentrations</li> <li>Dip-stick and spot-test forms are easy to use, effective, and comparatively inexpensive to produce</li> <li>Tests are reversible, reusable (with power source), and recyclable (disposable), thus reducing waste and costs</li> </ul>
Advancing Wound Treatment with Saloplastic Dressings Dr. Joseph Schlenoff 10-019 Garrett Edmunds gedmunds@fsu.edu <p>The demand for medical wound dressings is universal. Ranging in use from treating minor cuts to traumatic injuries, medical wound dressings prevent infections and save lives. In the case of traumatic injury, current wound dressings often require the application of a variety of materials, such as a combination of wound-filling gels, gauze, tape, and splints. However, Dr. Schlenoff’s research and discovery of saloplastics can decrease the number of necessary materials needed since saloplastic dressings can treat multiple aspects of a wound.</p> <p>The process of creating saloplastics uses salt instead of heat to melt plastics made from blends of charged polymers. By placing layers of positively and negatively charged electrolytes on top of one another, their electrical charges cancel each other out and create a neutrally charged, ultrathin film. These ultra-thin polymer coatings are useful for producing biocompatible surfaces that can be implanted into the human body for medical purposes.</p> <p>Approximately 750,000 Americans suffer strokes each year. Worldwide, that number increases to 20 million people. Primary stroke damage occurs from blood clotting and secondary damage occurs when toxic byproducts, including hemin, are produced from the trauma experienced during a stroke. This condition, known as hemin toxicity, leads to cell damage and cell death that in turn may cause irreparable brain damage or death for the individual.</p> <p>With Dr. Schlenoff’s research, stents used for implantation inside coronary arteries during surgical procedures could be coated with an ultrathin film that prevents cells and proteins from adhering, thus avoiding a narrowing of the arteries and restriction of blood flow.</p> <p><a rel="noopener" data-id="7055" href="/media/4155/marketing-document-polymer-schlenoff.pdf" target="_blank" title="Marketing document polymer schlenoff.pdf">Download PDF version</a></p> <h2>Applications:</h2> <ul> <li>First responder scenarios</li> <li>Chronic Wounds</li> <li>Medical practitioners to consumers</li> <li>Military</li> </ul> <h2>Advantages:</h2> <ul> <li>Antibacterial, moldable when wet, and cast-like when dry</li> <li>Low heating temperatures, 45 – 55 degrees C, are needed to soften the material.</li> <li>One material can treat multiple aspects of a wound.</li> <li>Within minutes, the most serious wounds and breaks can be sealed and immobilized.</li> </ul>
Computer Software that Reduces Known Risk Factors for Anxiety, Depression, and Related Issues Dr. Norman B. Schmidt 15-175 Michael Tentnowski mtentnowski@fsu.edu <p>According to the World Health Organization anxiety and related issues, including addictions and mood problems as well as suicide, represent some of the most prevalent and disabling conditions across all physical and mental health disorders. As such, there is a clear public health need to more effectively prevent, mitigate and treat these issues.</p> <p>Despite their prevalence and impairing nature, many of these problems respond remarkably well to treatment. It sounds almost too good to be true, but decades long conditions can be effectively removed in a few weeks with proper treatment. Our computer delivered interventions are even briefer – only about 50 minutes long. Despite their brevity, we have found that these interventions have considerable and long lasting positive benefits. Specifically, these brief treatments reduce the targeted risk factor by about 30% and these reductions are durable for as long as two years. Currently, we have two computer interventions - one focuses on stress sensitivity and the other on social isolation. These constructs have a considerable empirical foundation and are implicated as critical mechanisms involved in anxiety and mood problems.</p> <p>Our work in this area combines three key tasks: (1) identification of malleable risk factors, (2) developing interventions for these risk factors, and (3) using technology to facilitate delivery of the interventions.</p> <p>Technology is increasingly used to assist medical professionals. In regard to risk factors, our approach has been to develop interactive computer programs that guide participants through the information and skills needed to correct the problem of interest. These computer programs are brief (under one hour) and are readily disseminated via the web.</p> <p><a rel="noopener" href="https://psy.fsu.edu/faculty/schmidtb/schmidt.dp.php" target="_blank">More on Dr. Schmidt</a></p> <p> </p>
Homeless Shelter Infant Cradle Dr. Pable 08-168 Brent Edington bedington@fsu.edu <p>The present invention describes a cradle designed to be used for infants of families who reside in homeless shelters. This cradle design solves the problem of homeless families nurturing their infants in bed which creates a smothering hazard. The cradle, used in the context of an extremely small bedroom, has a unique construction that permits it to be pulled up close alongside the bed and allows the infant to be nurtured while the caregiver is in bed. Many shelters utilize prison-style beds with a unique under-bed storage unit that this work accommodates, allowing the cradle to be placed directly alongside the bed.</p> <p>The cradle's third prototype has been completed and the cradle has been placed in its end location (a local homeless shelter) that enabled a check for suitable dimensions and weight.This furniture object potentially represents a small, but potentially lifesaving improvement to homeless shelter family living dormitories.</p> <h2>Applications:</h2> <ul> <li>The potential scope of its use is vast, with the Department of Housing and Urban Development reporting 95,000 family beds in homeless shelters and an additional 3,000 family beds in transitional shelters nationwide (The 2nd Annual Homeless Report to Congress, March 2008).</li> </ul> <p> </p>
Quantitative Analysis of Metabolic Mixtures by 2D 13C-Constant-Time TOCSY NMR Spectroscopy Rafael Bruschweiler 13-204 Garrett Edmunds gedmunds@fsu.edu <p>Quantification of metabolite concentrations is a key task in metabolomics studies.</p> <p>Significant peak overlaps in 1D NMR spectra of metabolomics samples prevent straightforward quantification through 1D peak integrals.Using uniformly 13C-labeled organisms, the 2D NMR 13C-13C constant-time (CT) TOCSY experiment provides high-resolution information about individual metabolites that allows their identification via database searching or, in the case of novel compounds, through the reconstruction of their backbone-carbon topology.</p> <p>FSU researchers demonstrated how CT-TOCSY spectra can also be utilized for quantification purposes. The methods are demonstrated for carbohydrate and amino-acid mixtures.</p>
Genome Capture and Sequencing to Comprehensively Map Chromatin Structure in Complex Genomes Dr. Jonathan Dennis 14-044 Brent Edington bedington@fsu.edu <p>This invention brings significant improvement to our ability to query the chromatin structure of select important regions of the entire human genome. Utilizing a unique sequencing strategy, the invention offers a solution-based sequence capture method enabling the enrichment of the 2000 bp surrounding the transcription start site of 25,464 human open reading frames. This enrichment reduces the sequence space of the human genome from 3.4 Gb in total to 50 Mb of transcription start sites, a 98.5% reduction. Additionally, the enrichment is analogous to that achieved for well-documented exome sequencing experiments. This sequence capture approach will allow researchers to multiplex chromatin structure analyses in Illumina HiSeq2500 lanes, thereby opening this strategy for a wide range of diagnostic and prognostic indicators in human disease.</p> <h2>Applications:</h2> <ul> <li>Identify stages in the progression of cancer</li> <li>Identify host response in viral infection (HIV and KSHV)</li> <li>Define cryptic effects of drugs of abuse (amphetamines, cocaine, and nicotine)</li> </ul> <h2>Advantages:</h2> <ul> <li><span>Allows for the targeted analysis of specific areas of interest in complex genomes</span></li> <li><span>Provides a cost effective strategy for querying multiple samples in a single reaction</span></li> <li><span>Provides an extremely cost effective way to screen patient samples </span></li> <li><span>Opens a new field of biomarker development: distribution of nucleosomes</span></li> <li><span>Nucleosome distribution mapping is independent of genotype and gene expression</span></li> </ul>
A Reliable Assay for the Detection of Pork and Blood Components for Halal, Kosher, and Other Dietary Needs and Applications Yun-Hwa Hsieh 06-097, 12-194 Brent Edington bedington@fsu.edu <p>Nearly half of the world’s total population is strictly prohibited to consume pork and any substances derived from animal blood. However, food ingredients derived from pork and blood are widely used and present in various forms of dietary products without the awareness of consumers and even regulators.</p> <p>Analytical tools for monitoring these materials are lacking. Our laboratory at FSU possesses the only reliable technology to protect consumers who avoid eating products containing pork and blood, and such technology has been frequently sought for commercialization by a number of domestic and international companies for consumer protection in the markets of Kosher food for 13.8- million Jews; Halal foods for 1.6-billion Muslims; 1 billion of Hindus and non-religious vegans/vegetarians.</p> <p>The most desirable detection method is enzyme-linked immunosorbent assays (ELISA) which, coupled with our panel of monoclonal antibodies (mAbs) is able to detect protein ingredients derived from pork and blood components. These unique monoclonal antibodies are able to detect pork and blood from processed and cooked samples.</p>
Novel Application of Melatonin Antagonists in Obstetrical Practice Dr. Olcese 08-058 Brent Edington bedington@fsu.edu <p>This is a method for the prevention of pre-term labor that will introduce, intravenously, a melatonin antagonist to women who are predisposed to premature birth. Melatonin antagonists are drugs that do not provoke a biological response themselves, but bind to melatonin receptors, and, therefore, prevent endogenous melatonin itself from binding to the receptor. It is believed that the inhibition of melatonin action will prevent women from beginning labor.</p> <p>Melatonin is a naturally occurring neurohormone found in most animals, including humans. Its role in the body is associated with the maintenance of a biological clock, or circadian rhythm. Besides this function, it is also a powerful antioxidant. Melatonin, or melatonin analogues, are consumed daily by millions of people for sleep induction. However, the application of melatonin in obstetrics represents a completely novel approach to the management of labor.</p> <p><a href="/media/3989/olcese2.pdf" title="olcese2.pdf" data-id="6638">Download PDF Version</a> </p> <h2>Applications:</h2> <ul> <li>Method for using melatonin to delay pre-term labor by targeting mothers who are at risk for premature labor.</li> </ul> <h2>Advantages:</h2> <ul> <li>Delay pre-term labor</li> <li>Save millions of dollars from premature births each year</li> <li>Prevent thousands of work hours for healthcare providers each year</li> <li>No expensive new drug development</li> </ul>
A Prosthetic Socket System with an Unprecedented Degree of Multifunctionality and Integration Dr. Chun (Chuck) Zhang 12-160 Brittany Ferraro bferraro@fsu.edu <p>The proposed prosthetic Socket Optimized for Comfort with Advanced Technologies (SOCAT) integrate advanced materials, nanotechnology, electronics, and manufacturing technologies to achieve a prosthetic socket system with an unprecedented degree of multifunctionality and integration to meet the critical needs for advanced prostheses for patients. Despite the significant advances made in the past decade in the area of prosthetics, discomfort and adverse effects on the skin as a result of poor fit, elevated temperatures and moisture accumulation within the prosthetic socket are still a major problem.</p> <p>The proposed SOCAT invention utilizes four enabling technologies augmented with a product integration design to form a holistic above-knee socket system to resolve the issues mentioned above:</p> <ol> <li>Volume/shape change management will be realized with advanced materials that sense and respond to external stimuli, such as pressure changes due to either volume changes as a result of residual limb swelling or muscle tissue shape changes during a gait cycle</li> <li>Pistoning control and skin breakdown prevention will be realized via an innovative interface material embedded with nanoparticles</li> <li>Temperature and sweat control will be achieved by solid state active cooling using an array of miniature thermoelectric devices in combination with nanomaterials and phase change materials; and</li> <li>Lightweight piezoelectric nanofoam pressure sensors and printed electronic temperature and moisture sensors fully embedded in liners will provide the patient with an early warning of adverse situations, such as abnormal pressure suggesting improper gait or pistoning, and allow the practitioner to remotely collect real-time data for subsequent analysis.</li> </ol> <h2>Advantages:</h2> <ul> <li>Fully integrated product design that addresses major concerns of current sockets while minimizing parasitic parts and devices</li> <li>Lightweight, multifunctional material-enabled socket system</li> <li>Adaptive volume change management with coupled sensing/actuation materials</li> <li>Biomimetic materials for anti-microbial function and pistoning control</li> <li>Thermal management and perspiration control with solid state active cooling in conjunction with novel nanomaterials and phase changing materials</li> <li>Whole-field pressure monitoring by innovative lightweight piezoelectric materials</li> <li>Embedded printed electronics interconnects for sensing, wireless communication and local data storage</li> </ul>
A Novel Cell Culture System for Hepatitis C Virus (HCV) Dr. Tang 06-028 Brent Edington bedington@fsu.edu <p>This new culture system creates stem cell-derived human hepatocyte-like cells which are Hepatitis C Virus (HCV) infectable. This FSU-created technology establishes a new noncancerous and renewable cell culture system for HCV infection; enables direct infection by patient sera in vitro; identifies a defined transition to HCV permissiveness during hepatocyte differentiation; and demonstrates the feasibility of generating viral-resistant human hepatocyte-like cells in vitro.</p> <p>Primary human hepatocytes (PHHs) isolated from patient biopsies represent the most physiologically relevant cell culture model for hepatitis C virus (HCV) infection. However, these primary cells are not readily accessible, display individual variability, and are largely refractory to genetic manipulation. The  hepatocyte-like cells derived from stem cells not only overcomes these shortcomings but can also provide an unlimited source of non-cancer cells for both research and cell therapy. The system reports a novel infection model based upon differentiated human hepatocyte-like cells (DHHs) derived from stem cells, including human embryonic (hESCs) and induced pluripotent stem cells (iPSCs). Differentiated human hepatocyte-like cells (DHHs) derived from pluripotent stem cells have demonstrated hepatic functions but have not been explored for HCV infection studies as here. The ability to directly infect cultured cells with HCV patient serum, to study defined stages of viral permissiveness, and to produce genetically modified cells with desired phenotypes all have broad significance for host-pathogen interactions, drug resistance analysis and drug therapy.</p> <p><a href="/media/3986/tang4.pdf" title="tang4.pdf" data-id="6635">Download PDF Version</a> </p> <h2>Applications:</h2> <ul> <li>An HCV platform for drug-resistance analysis</li> <li>Infection studies and metabolic studies</li> </ul>
Novel Methods to Regulate Uterine Contractions Dr. Olcese 12-239 Brent Edington bedington@fsu.edu <p>The present invention describes a novel method of regulating uterine contractions in pregnant female using light. The method of regulating uterine contractions comprises suppressing a nocturnal endogenous melatonin level of a pregnant female experiencing uterine contractions by exposing the pregnant female during nighttime to a light source emitting visible light. Directing light from a light source positioned about 1 meter from the eyes, emitting predominantly blue light onto the pregnant females eyes between 9 p.m. to 6 a.m., with an intensity of about 10,000 lux of the visible light is sufficient to suppress the pregnant female's endogenous melatonin level.</p> <p>The results reveal that regular nocturnal contractions are suppressed by bright light exposure under these conditions. This finding supports the proposition that melatonin is a key zeitgeber, regulating the onset of human labor and parturition and that light can be used to regulate melatonin levels and, thereby, regulate uterine contractions. Optionally, the light source is adapted to emit light in discrete on/off cycles or pulses. The duration of the pulses and the separation between successive pulses is adjusted to obtain the desired amount of endogenous melatonin suppression.</p> <p>This invention will open new avenues for the management of term and preterm labor.</p>
Carbon Nanotube and Polymeric Thin Film Assemblies for Pressure Sensing and Mapping Dr. Liang, Dr. Lu, Dr, Whang and Dr. Zhang 08-132 Brittany Ferraro bferraro@fsu.edu <p>Pressure/force sensing technologies are used in a broad range of applications. Many pressure/force sensors are available, but thin film sensors are limited. Currently, the most common film pressure sensors are either resistive or capacitive, which are both reusable. This new technology utilizes the rupture of microcapsules filled with dyes for pressure sensing to create a disposable thin film mapping.</p> <p>The sensing assembly is composed of a top and bottom element. The top element is made of elastomer-like polymer with grooves that are filled with polymer gel electrolyte and the bottom is made of patterned conducting material thin film strips on top of flexible polymer film. When pressure is applied, a deformation of the material in the top element causes the gel to come in contact with the film strips, which creates an ionic-conducting path.</p> <p><a data-id="6119" href="/media/3841/liu2.pdf" title="Liu2.pdf">Download PDF Version</a> </p> <h2>Applications:</h2> <ul> <li>Seat occupancy detection in the automobile industry</li> <li>Tactile feedback for robots to sense and respond to environments</li> <li>Rehabilitation progress monitoring in the medical industry</li> <li>Bite force mapping in dentistry</li> <li>Measuring force of golf grips</li> </ul> <h2>Advantages:</h2> <ul> <li>Disposable</li> <li>Low percolation threshold</li> <li>Detects low levels of pressure sensing</li> <li>Utilizes ionic conduction as the major sensing mechanism</li> </ul>
Immunoglobulin Peptides Against Heated Bovine Blood Dr. Hsieh 06-097 Brent Edington bedington@fsu.edu <p>Transmissible spongiform encephalopathy (TSE) agents induce fatal neurodegenerative diseases in mammalian species and humans. Bovine spongiform encephalopathy (BSE) in cattle, commonly known as mad cow disease, has brought enormous economic consequences since its first incidence in the United Kingdom in 1986. In addition, the emergence of a new variant form of Creutzfeldt-Jakob Disease (vCJD) in humans in the United Kingdom has been proposed to be possibly linked with BSE. Meat and bone meal, an ingredient of animal feed, contaminated with a TSE agent was believed to be the major vehicle of BSE transmission, according to epidemiological inquiry. To prevent the spread of BSE, the European Union in 1988 banned the inclusion of ruminant-derived proteins in animal feed. The U.S. Food and Drug Administration also introduced the feed ban in 1997 to prohibit the use of proteins derived from mammalian tissues in feeding ruminants</p> <p>Tools that permit enforcement of the meat and bone meal bans to eradicate BSE are becoming increasingly important for compliance with animal byproduct regulation. Furthermore, the accurate labeling of meat products is mandated and monitored by the United States Department of Agriculture (USDA) as well as by state and local governments.</p> <p>Among the various aspects of the present invention are immunoglobulin peptides which bind an antigen from bovine blood that may be used, for example, in a screening assay to identify or detect exogenous blood. The method comprises combining the sample with an immunoglobulin peptide which binds a thermostable antigen from bovine blood and determining whether any antigen from the sample was bound by the immunoglobulin peptide. This method can be used to determine the presence of bovine blood in a food sample or an animal feed sample.</p>

Cessation of Smoking System Brigitta Nuccio & Andree Aubrey 18-055 Brent Edington bedington@fsu.edu <p>This cessation of smoking method is an evidence-based curriculum for delivering both group and individual cessation interventions. It can be used cost-effectively in community based programs and across multiple components of a health system including primary and specialty clinics, behavioral health programs, and hospitals.</p> <p>The participant workbook contains six sessions or modules and serves as a guide to the tobacco cessation process. The workbook walks participants through the critical steps of making a quit attempt and addresses physical addiction to nicotine, psychological dependence, behavioral habit, and social/cultural influences. In the workbook participants will complete motivational activities, document a specific quit date, outline their quit strategies and have additional information for reference that may not get covered in the counseling sessions. Even participants who attend only one session may use the workbook to make an independent quit attempt. The workbook is designed in a way that it can be used for independent study if a tobacco user wants to quit but is not interested in attending a group. </p>
Anti-Flavivirus Compounds for Zika Virus and Dengue Virus Infections Hengli Tang 19-003 Brent Edington bedington@fsu.edu <p>Zika virus, a mosquito-borne flavivirus, has recently re-emerged and spread across the Western Hemisphere after it had remained in relative obscurity for many years. Zika virial infection causes many of the same symptoms caused by dengue viruses or chikungunya virus. Unlike these viruses Zika virus causes congenital defects, including microcephaly, and is also associated with Guillain-Barre syndrome in infected adults.</p> <p>Through a combination of computational modeling and screening, a portfolio of 19 compounds has been identified which have antiviral activity against Zika virus. In some cases, these drugs have activity against Zika virus and dengue viral infections. These compounds may be used in new therapies for the treatment of infection with flaviviruses, such as Zika virus and dengue virus.</p>
Monoclonal Antibodies Targeting Zika Viris Envelope Proteins Hengli Tang 17-037 Brent Edington bedington@fsu.edu <p> </p> <p>Due to the nascent nature of Zika Virus research reagents specific for the Zika Virus such as monoclonal antibodies are not widely available. FSU researchers have produced monoclonal antibodies to the Zika virus. These monoclonal antibodies are targeted to the envelope proteins NS1 and NS5. They enable detection of Zika infection, development of diagnostics, and can also be used as control reagents in research.</p>
Inhibiting Neuroinflammation Due to a Brain Injury with D-Serine Sanjay Kumar 19-037 Brent Edington bedington@fsu.edu <p>D-serine is an antagonist of GluN2 containing triheteromeric NMDA receptors found in the temporal lobe of the brain. It has been shown that D-serine may be used to treat neurological disorders, such as epilepsy, that cause seizures.</p> <p>Unexpectedly, it was recently discovered that D-serine inhibits neuroinflammation of brain cells after a brain injury by reducing the neurotoxic immune response of glial cells after the injury. Accordingly, D-serine may be used in the treatment of brain injuries to help prevent neural cell loss caused by harmful immune responses. Following brain injury an immune response is triggered and immune cells are directed to and sequestered to the site of injury. These immune cells release cytokines that exasperate the survivability of healthy neurons. Application of D-serine stopes the infiltration of these immune response cells to the site of injury, thereby preventing loss of healthy neurons by reducing the neuroinflammation response.</p>
Universal Insulin Pump Leakage Detection System John Wilcox 17-014 Garrett Edmunds gedmunds@fsu.edu <p>Insulin pump technology is a commonly implemented form of treatment for patients who suffer complications from diabetes mellitus. Mechanical malfunctions associated with the infusion site are a common source of failure and frustration experienced by many patients with these devices. Cannula dislodgement, lipohypotophy, and internal pump occlusions may result in leakage of insulin from the infusion site onto the surrounding adhesive material. For many, the only form of detection are the symptoms associated with hyperglycemia.</p> <p>This technology is a practical method for detecting these leaks as they occur. A mixture of 4-aminoantipyrine and potassium persulfate is deposited onto the surface of the adhesive holding the cannula. When exposed to the insulin solution, these compounds react to turn a bright blue color, indicating to the wearer that a leak is occurring and prompting them to change out their injection site. This allows people with diabetes to better control their blood glucose levels and avoid leakages.</p>
Inhibition of Vascular Endothelial Cell-Mediated Phagocytic Processes for Treatment of Demyelinating Conditions Yen Ri 19-006 Brent Edington bedington@fsu.edu <p>The present invention concerns a method for treating a demyelinating condition by administering an agent that inhibits vascular endothelial cell phagocytosis. The method of the invention is useful in treating demyelinating conditions associated with an injury such as a spinal cord injury or traumatic brain injury as well as other demyelinating conditions such as multiple sclerosis.</p> <p>The inventor has established a previously unidentified role for microvascular endothelial cells (EC) which have been shown to engulf and clear myelin debris in spinal cord injury and multiple sclerosis animal model systems. The inventor also discovered a novel pathway for myelin debris degradation through the autophagy-lysosome system. Importantly, the inventor demonstrated for the first time that microvascular EC uptake exerts critical functions beyond myelin debris clearance. Engulfment and autophagic processing of myelin debris by microvascular ECs have sequential consequences in promoting chronic inflammation and pathological healing (angiogenesis and fibrotic scar formation) during the progression of demyelinating disorders. Therefore, this research reveals how myelin debris engulfment and processing by microvascular ECs contribute to pathological progression in demyelinating disorders.</p>
Anti-fibrotic Drugs Targeting Synthesis of Type 1 Collagen Branko Stefanovi 10-042, 12-047, 17-024, 19-034, and 20-047 Brent Edington bedington@fsu.edu <p>Fibrosis affects 45% of the population in the USA. It is characterized by excessive synthesis of type 1 collagen and scarring of various organs. This leads to organ insufficiency and death. The process is chronic and progressive and there are no approved drugs that can inhibit collagen synthesis. Aspects of the regulation of type 1 collagen production have been delineated and a drug screening procedure based on disruption of the regulatory pathway has been devised. Using this screening procedure a library of chemicals compounds has been screened and nine compounds that can inhibit collagen synthesis in cultured cells between 50-90% have been found.</p> <p>This is a completely novel approach to finding antifibrotic drugs. If these compounds prove to be effective in humans, they will be the first chemicals that can directly inhibit collagen production. Since there is no cure for fibrosis, they may represent the first specific antifibrotic drugs.</p> <p>This technology consists of two novel assay systems and three potential antifibrosis drugs.</p>
A Method for Screening Patients’ Cells for Response to Steroids Prior to Initiating Steroid Therapy Akash Gunjan 20-035 Brent Edington bedington@fsu.edu <p>Steroids are commonly prescribed medications in the US and around the world. Topical steroids are used extensively to treat a wide range of skin disorders such as psoriasis, eczema and dermatitis, while local steroid injections are a mainline therapy for benign fibrotic skin tumors know as keloids. Additionally, oral steroids are to treat systemic autoimmune conditions, while inhaled steroids serve as the mainline therapy for long-term control of asthma and nasal allergies. However, there is a wide variation in the response of patients to steroid therapy. For example, only about 34% of keloid patients benefit from steroid therapy, while 49% do not respond to it and the remaining 17% of patients actually see a worsening of their symptoms upon steroid therapy. This variability in patients' responses to steroids is likely due to individual differences in the patients’ genetic or epigenetic makeup, although the genes or epigenetic pathways involved have not yet been identified. The highly variable patient responses to steroid therapy highlight the dire need for a screening test to determine patients’ response to steroids prior to initiating therapy.</p> <p>Fortunately, since all of our cells reflect our genetic/epigenetic makeup, they are also potentially capable of accurately reporting our response to steroids. Hence, as long as we can obtain viable cells from patients, we can test them for sensitivity to steroids. We have developed a simple method for screening patient cells obtained from a small biopsy samples and culturing them to determine the effects of steroids using an in vitro cell proliferation assay.</p>
Treatment of Human Coronavirus Infections using Alpha Glucosidase Glycoprotein Processing Inhibitors Eric Holmes & Gary Ostrander 20-037 Brent Edington bedington@fsu.edu <p>Coronaviruses cause illness in adults and children ranging from the common cold to more severe diseases. Common signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, coronavirus infection can cause pneumonia, severe acute respiratory syndrome (SARS), kidney failure, and even death.</p> <p>Coronaviruses are zoonotic, meaning they are transmitted between animals and humans. Several known coronaviruses are circulating in animals that have not yet infected humans. A novel coronavirus (nCo V) is a new strain that has not been previously identified in humans. There are currently no vaccines or antiviral drugs to prevent or treat human coronavirus infections.</p> <p>The present invention concerns the use of alpha-glucosidase glycoprotein processing inhibitors for the treatment or prevention of human coronavirus infections.</p> <p> </p>
Niclosamide Formulations and Methods of Use Eric Holmes & Gary Ostrander 20-051 Brent Edington bedington@fsu.edu <p>Niclosamide is widely used as an oral medication for various tapeworm infections and has also been shown to be effective inhibitor of viral replication and infection.  The invention involves a  Niclosamide formulation utilizing permeability enhancers used to increase the amount of Niclosamide capable of being taken up by cells. The Niclosamide formulation has been shown to increase cellular uptake by as much as 150%. This Niclosamide formulation may be used to enhance delivery of Niclosamide in the treatment of human coronavirus or flavivirus infections.</p>
Selective Treatment of Cancers Having Histone H3 Mutations and Aberrant Levels of DNA or Histone Methylation or Acetylation, or Defects in Homologous Recombination Akash Gunjan 16-092 Brent Edington bedington@fsu.edu <p>Mutations in the DNA packaging and regulatory protein histone H3 and its primary sequence variants drive specific types of predominantly pediatric cancers, including the 10 incurable high-grade brain stem gliomas known as Diffuse Intrinsic Pontine Gliomas (DIPG). Up to 90% of DIPG tumors carry the lysine 27 to methionine (K27M) mutation in histone H3 variants, usually the histone H3.3 variant.  H3 K27M mutant high-grade pediatric gliomas such as DIPG do not currently have any approved therapies and are 100% fatal. The present invention is a therapeutic approach which targets specific molecular pathways that are aberrant only in the mutant tumor cells but not the wild type cells, i.e., a therapy in which only the H3 mutant tumor cells would be eliminated specifically, while the normal cells carrying wild type H3 would be largely spared.</p> <p>This targeted approach can be pursued is a few different ways that are the focus of this invention.  </p> <p> </p>
Flexible and Eco-Friendly X-ray Scintillators Dr. Biwu Ma 20-031 Garrett Edmunds gedmunds@fsu.edu <p>Dr. Ma has recently developed highly efficient X-ray scintillators with state-of-the-art performance based on organic metal halide hybrids, which could be prepared using a facile solution growth method at room temperature to form inch-sized single crystals. These organic-inorganic hybrid materials with a zero-dimensional<br />(0D) structure at the molecular level exhibit tunable emissions in the visible spectrum region with high photoluminescence quantum efficiencies (PLQEs) of up to 100%. X-ray imaging tests have showed that scintillators based on powders could provide an excellent visualization tool for X-ray radiography, and<br />flexible scintillators could be fabricated by blending powders with polymer matrix, such as polydimethylsiloxane (PDMS). </p> <p>These X-ray scintillators have numerous advantages over currently-used materials:</p> <ol> <li>The scintillation materials are low cost (~ 1/10 of commercially available products), i.e. room<br />temperature facile synthesis using abundant low cost raw materials;</li> <li>The scintillation materials are eco-friendly materials, i.e. lead-free, heavy metal-free;</li> <li>The X-ray scintillation characteristics are exceptional, i.e. higher light yields than most of the<br />conventional commercially available scintillation materials;</li> <li>It is straightforward to integrate scintillation materials with polymer matrices to make flexible X-ray material</li> </ol>
Motivational Interviewing Sylvie Naar 19-023 Brent Edington bedington@fsu.edu <p>Motivational Interviewing (MI) is often recommended as an evidence-based approach to behavior change. It is a collaborative, goal-oriented communication with attention to the language of change. MI is designed to strengthen personal motivation and commitment to specific goals by supporting and eliciting the individual’s reasons for change.</p> <p>MI is:</p> <ul> <li>A style of communication that guides the individual and it resides between good listening and providing advice;</li> <li>Designated to empower people to change by bringing out their own reasons to change;</li> </ul> <p>MI is used when:</p> <ul> <li>Ambivalence is high;</li> <li>Confidence is low;</li> <li>Desire to change is low;</li> <li>Motivation to change is low.</li> </ul> <p>Dr. Sylvie Naar has developed a rating scale for coding interactions for competency in Motivational Interviewing and a method of communication to promote behavior change. This rating scale and method require less time and expense for the client and has been rigorously tested in health care settings. Dr. Naar’s rating scale and guidelines for use provide a straightforward method for the use of Motivational Interviewing. This method has been verified in clinical settings and the guidelines are clear and concise.</p> <p>The rating scale and guidelines are protected by copyright.</p> <p> </p>
Halide Perovskite-Polymer Composites for High Energy Photon Detection and Protection Dr. Zhibin Yu 18-048 Brittany Ferraro bferraro@fsu.edu <p>An FSU researcher created a novel material comprised of halide perovskite crystals embedded in a polymer matrix for radiation blocking and detection. The material is lightweight and lead free. Other materials require expensive and long manufacturing processes, but this novel material can be manufactured in a variety of ways such as solution-based drop casting, hot pressing, melt extrusion, injection molding, and 3D printing, to save time and money. Electrodes can be embedded in the material for passive and accurate x-ray and gamma-ray detection.  </p> <p>Third party independent testing has shown that the material is 50% more effective than current state of the art radiation blocking technology. These semiconducting nanocrystals are uniformly dispersed in the polymer matrix to not only block radiation but also detect high energy radiation.</p>
MORIARTY: A Rapid, Highly Sensitive, Nucleic Acid Detection Method Dr. Hong Li 21-044 Garrett Edmunds gedmunds@fsu.edu <p>The COVID-19 Pandemic demonstrated the need for rapid, affordable, and accurate virus testing methods. While the standard Polymerase Chain Reaction (PCR)-based methods remain effective and widely used, they require hours to complete and are unable to directly detect virus variants and other subtle changes to genetic material. Additionally, PCR lacks the possibility for testing under limited resources.</p> <p>MORIARTY (an acronym for <u>M</u>ultipronged, <u>O</u>ne-pot, <u>R</u>NA-<u>I</u>nduced, <u>A</u>ffordable, <u>R</u>apid, <u>T</u>est s<u>Y</u>stem) is an enzyme-based method that can detect nucleic acids from a variety of sources, including the SARS-CoV2 coronavirus, seasonal flu varieties, and circulating tumor DNA for early cancer detection. This detection method is consistent with the accuracy of PCR methods but is considerably faster does not require costly equipment, with results available in as little as 15 minutes.</p> <p>The technology utilizes CRISPR-Cas enzymes to detect genetic material and induce a fluorescent signal. The system can be easily repurposed and reprogramed for any genetic material detection, including viral RNA, viral DNA, and ctDNA, and can be used to detect variants with single-nucleotide resolution. This fidelity, for example, can detect the difference between the various coronavirus variants with the same point-of-care test. It can also be used for liquid biopsies to test for ctDNA for various cancers.</p>
Extracellular Vesical-based Cytokine Storm Therapy Zucai Suo 21-039 Brent Edington bedington@fsu.edu <p>A cytokine storm, also called hypercytokinemia, is a life-threatening physiological reaction in humans and other animals in which the immune systems causes an uncontrolled and excessive release of pro-inflammatory cytokines. Although cytokines are part of the body’s normal immune response to infection, their uncontrolled sudden release in large quantities can cause multisystem organ failure and even death. In some severe cases of microbial infection such as the flu virus and COVID-19, cytokine production can increase out of control. This excessive immune response can, in some cases, cause an immune response that can damage internal organs.</p> <p>CD24 is a protein normally expressed in humans. A modification of CD24, soluble CD24 (CD24Fc), is a biological immunomodulator that may be used for treating hyper-inflammation and cytokine storm conditions. Soluble CD24 has been shown to inhibit secretion of inflammatory cytokines and is involved in clinical trials for reduction of cytokine storm caused by COVID-19 infection.</p> <p>This invention incorporates the use of exosomes and liposomes as a delivery vehicle for soluble CD24. Exosomes and liposomes are loaded with soluble CD24 using a proprietary process developed by Dr. Suo. This process results in high levels of compounds incorporated on the surface and interior of exosomes and liposomes. The exosomes and liposomes protect the compounds until they are delivered to the appropriate target.</p>
Transcranial Stimulation to Treat DMN Dysfunction Wen Li 22-035 Michael Tentnowski mtentnowski@fsu.edu <p>This technology is directly applied to people with mild cognitive impairment and Alzheimer’s disease to alleviate symptoms and improve life quality. It builds upon non-invasive brain stimulation (NIBS), specifically transcranial alternating current stimulation (tACS) that applies a relatively low-intensity sinusoid current through the scalp to stimulate the brain. It targets a major neural network (the default mode network/DMN), which breaks down with normal aging, precipitously in mild cognitive impairment and severely in Alzheimer’s disease.  The application is non-invasive, safe, and user-friendly and has a strong potential to be applied as therapeutics and prophylactics for cognitive impairment and dementia.</p> Psychology,Alzheimer's,Aging,Dementia
Topical Oxytocin Treatment with Tactile Stimulation Elizabeth Hammock 22-058 Michael Tentnowski mtentnowski@fsu.edu <p>Oxytocin is an FDA approved drug (and naturally produced hormone) that is used intravenously for labor induction. Currently, oxytocin is delivered by uncomfortable (intranasal) or invasive (injection) methods. This treatment combines oxytocin receptor modulation with somatosensory stimulation through topical substance delivery. Oxytocin or other oxytocin receptor modulators will be combined with drug delivery vehicles that require somatosensory stimulation as part of their application. Topical application of oxytocin may be delivered in shampoos, soaps, lotions, creams, ointments, massage oils, wipes, chewing gum, toothpastes, personal lubricants, condoms or other mechanisms of substance delivery that involve somatosensory stimulation (e.g., massage, ‘mouthfeel’ of foods/gums/candies, and sexual activity).</p>
Magnetic Levitation Simulator with Large Functional Volume Wei Guo 22-023 Michael Tentnowski mtentnowski@fsu.edu <p>Reduced gravity is known to have important effects on various biological and physical systems. Weightless may prohibit cell culture growth and cause cellular stressors and bone loss that can negatively impact astronauts’ health.  In fluid systems, reduced gravity can significantly affect the sloshing dynamics of cryogenic propellants in spacecrafts, surface oscillation of liquid drops, bubble cavitation, and boiling heat transfer in fluids.  The positive potential of reduced gravity in the growth of tissue and crystals has been recognized as well.</p>
Rapid and Cost-Effective Isolation and Genotyping of Genomic Regions Alan Lemmon 22-020 Michael Tentnowski mtentnowksi@fsu.edu <p>A method of using a combination of adapter design, hairpinning and exonuclease digestion to enrich samples for target regions of the genome using minimal laboratory effort and produces DNA libraries that can be sequenced. This process allows a rapid and inexpensive way to obtain genotype data in any organism, while avoiding the primary limiting factor of multiplex PCR: primer dimer. This is more flexible in terms of the type of genomic markers that can be evaluated, including SNP, STR (micro satellites), and longer DNA sequence variations.</p> <p>The technology can be used to obtain randomly distributed (unbiased) markers, or specific genomic regions. The number of regions targeted is also flexible and dramatically reduces upfront development time. Bioinformatic analyses of existing genomes or preliminary DNA sequence data can be conducted quickly to ascertain the most appropriate probes.</p>
