Intralipid as a Contrast Agent to Enhance Subsurface Blood Flow Imaging

This technology includes a blood flow imaging method that allows for a higher density of smaller particles to be detected. Current imaging methods that are based on Doppler measurements are limited by the discontinuity in the capillary flow in the space between red blood cells. The core technology is to use a scattering agent to enhance capillary flow or microcirculation. This technology has been tested for optical coherence Doppler tomography, but can be expended to any Doppler based flow imaging techniques such as laser speckle imaging.

Cannabinoid Receptor Meditating Compounds for Metabolic Disease

There is evidence that the metabolic effects of endocannabinoids are mediated by CB1 receptors in peripheral tissues. While prior attempts at generating CB1 receptor blockers have had serious neuropsychiatric side effects, inventors at NIH have discovered compounds that block CB1 receptors with reduced brain penetrance. In addition, some of these compounds also have a direct inhibitory effect on inducible nitric oxide synthase (iNOS), whereas another group of the compounds directly activates AMP kinas.

Treatment for Wolfram Syndrome and Other Endoplasmic Reticulum Stress Disorders with Endoplasmic Reticulum Calcium Modulators

This technology includes the use of JTV-519 and oxidized form of JTV-519, as a novel treatment for Wolfram syndrome and other diseases associated with endoplasmic reticulum (ER). JTV-519 can prevent the leakage of ER calcium to the cytosol and abnormal activation of a pro-apoptotic enzyme, calpain 2, in cell models of Wolfram syndrome. Further, these compounds can prevent cell death in beta cell models of these diseases.

Fluorinated MU-Opioid Receptor Agonists

Summary: 
Investigators at the National Institute on Drug Abuse seek co-development partners and/or licensees for collection of mu opioid receptor (MOR) agonists as alternatives for existing compounds.

Description of Technology: 
Although existing opioids are excellent analgesics and useful as positron emission tomography (PET) radiotracers, they come with debilitating side effects. These include addiction, respiratory distress, hyperalgesia, and constipation. Therefore, there is a need for alternatives with lower adverse effects.

A Protocol to Enhance Therapeutic Effects of Transcranial Magnetic Stimulation and the Methods to Realize It

Summary: 

The National Institute on Drug Abuse (NIDA) seeks research co-development partners and/or licensees for a high-powered electronic device and coil that delivers Transcranial Magnetic Stimulation (TMS) pulses as well as the software that controls the device for treating treatment resistant depression, substance use disorders and other CNS disorders.

Novel Human Islet Amyloid Polypeptides as Alzheimer’s Disease Biomarkers and Inhibitors of Amyloid Formation

Over 34 million Americans are living with diabetes. An estimated 6.5 million Americans are living with Alzheimer’s disease (AD) and type 2 diabetes mellites (T2DM). Amyloidosis due to aggregation of amyloid-β is key pathogenic event in AD, whereas aggregation of mature islet amyloid polypeptide (IAPP37) in human islet leads to β-cell dysfunction. A hallmark feature of T2DM is the accumulation of islet amyloid polypeptide fibrils in pancreatic islets. Such accumulations form amyloid plaques and cause apoptosis of -cells of islets. 

Novel Human Insulin Cα-Peptide as an Antagonist for Islet and Brain Amyloidosis

Over 32 million Americans are living with Diabetes and newly diagnosed cases of type 1 and type 2 diabetes is increasing. A defining feature of type 2 diabetes mellitus (T2DM) is the accumulation of islet amyloid polypeptide (IAPP) fibrils in pancreatic islets. Such accumulations form amyloid plaques, referred to as islet amyloidosis. Mounting evidence suggests that islet amyloidosis plays a causative role in the development and progression of ß-cell dysfunction in T2DM.

Dopamine D3 Receptor Agonist Compounds, Methods of Preparation, Intermediates Thereof, and their Methods of Use

Due to the large degree of homology among dopamine D2-like receptors, discovering ligands capable of discriminating between the D2, D3, and D4 receptor subtypes remains a significant challenge. The development of subtype-selective pharmaceutical small molecules to activate (agonists) signals regulated by D2-like receptors has been especially difficult. 

A Most Efficient and Convergent Principal Component Analysis (PCA) Method for Big Data

Big data usually means big sample size with many outliers, in which traditional scalable L2-norm principal component analysis (L2-PCA) will fail. Current existing L1-norm PCA (L1-PCA) methods can improve robustness over outliers, however, its scalability is usually limited in either sample size or dimension size.  The inventor proposes an online flipping method to solve L1-PCA challenges, which is not only convergent asymptotically (or with big data), but also achieves most efficiency in the sense each sample is visited only once to extract one principal component (PC).

Novel Biased Potent Opioid-Like Agonists as Improved Medications to Treat Chronic and Acute Pain

There are no analgesics to ameliorate chronic pain without adverse side-effects (e.g., respiratory depression, gastrointestinal effects, tolerance, dependence), thus forcing patients into a difficult choice of negative impacts on quality of life. Most of the analgesics used for chronic and acute pain are drugs such as oxycodone, morphine, oxymorphone, and codeine. All of these opioids have been subject to misuse; prescription drug abuse is a severe problem worldwide, causing high mortality and greatly increased emergency room visits.
