PROJECT SUMMARY Over million people worldwide including million people in the USA are HIV positive HIV associated sensory neuropathy HIV SN is the most frequent neurological manifestation of HIV and is characterized as a distal symmetrical predominantly sensory polyneuropathy HIV SN may represent clinically indistinguishable neuropathies with distinct pathogenesis a distal axona ...

Abstract This proposal will lead to a Breakthrough sub cellular D chemical composition research platform for live cells based on the new invention of sub micron confocal photothermal IR micro spectroscopy CPIR Label free sub micron chemical imaging and spectroscopy has long been sought for visualization of biomolecules and materials in complex living systems Many diseases first manifest ...

PROJECT SUMMARY Fragile X syndromeFXSis the most common inheritable form of cognitive impairment and the leading known genetic cause of autismFXS is caused by the loss of expression of the fragile X mental retardation proteinFMRPA major challenge for FXS research is to develop treatment strategies that improve the intellectual capabilities of patientsDysregulated protein synthesis is widely accept ...

Because of its high sensitivitypolymerase chain reactionPCRis the gold standard for the diagnosis of many infectious diseasesbut generally only implemented in well equipped laboratoriesOne of the major roadblocks for expanding PCR to point of care markets is the lack of simplerobustsingle tube PCR designs which preserve its laboratory based high sensitivity and specificityIn this Fast Track STTR a ...

PROJECT SUMMARYABSTRACTBreast cancer is the second leading cause of death in females with cancerInapproximatelynew cases of invasive breast cancer were diagnosedwhere an estimate ofwas expected to succumb to their diseaseIt is estimated that one in eight women will develop breast cancer in their lifetimeBreast cancer is classified into subtypes based on the expression of estrogen receptorERprogest ...

Abstract Caveolae at the endothelial cells surface can selectively rapidly and actively pump targeted antibodies out of the bloodstream and into underlying tissue in vivo even when they are conjugated to high molecular weight cargo Based on this exciting recent discovery we also found that caveolae pumping system enables unprecedented tumor specific targeting and penetration Taken together ...

Abstract Acne dysbiosis is defined as microbial imbalance with the over growth of Propionibacterium acnes P acnes in the acne microbiome We have demonstrated that Staphylococcus epidermidis S epidermidis a probiotic bacterium co existed with P acnes in an acne lesion can exploit the carbohydrate fermentation to produce short chain fatty acids SCFAs and rein in the over growth of P ac ...

ABSTRACT Dental implants are a central part of modern dental practice with the overall market for replacement and reconstruction of teeth expected to reach over $billion in the next several yearsIt is estimated that overmillion people in the United States are missing all of the teeth in one or both of their jaws leading to lower quality of lifeMost of these implants will be successful for long ter ...

Summary The use of mass spectrometry MS for quantitative protein characterization has increased dramatically identifying and quantifying thousands of proteins is no longer a heroic task nor is characterizing therapeutic proteins in detail Due to widely available software quantitative mass spectrometry has become routine and widely used for addressing questions in basic biology translational ...

Summary Technology for studying the higher order structure HOS of biomolecules encompasses some of the most important tools in all of science and is a highlighted NIGMS research topic Mass spectrometric methods for studying HOS include oxidative footprinting and other methods to covalently label amino acid side chain functional groups and also hydrogen deuterium exchange HDX on protein bac ...
