Phenylthiocarbamide (PTC) Taste Receptor

Bitter taste has evolved in mammals as a central warning signal against ingestion of poisonous or toxic compounds. However, many beneficial compounds are also bitter and taste masking of bitter tasting pharmaceutical compounds is a billion dollar industry. The diversity of compounds that elicit bitter-taste sensations is vast and more than two dozen members of the TAS2R bitter taste receptor gene family have been identified.

Construction of Recombinant Baculoviruses Carrying the Gene Encoding the Major Capsid Protein, VP1, From Calicivirus Strains (Including Norovirus Strains Toronto, Hawaii, Desert Shield, Snow Mountain, and MD145-12)

The noroviruses (known as "Norwalk-like viruses") are associated with an estimated 23,000,000 cases of acute gastroenteritis in the United States each year. Norovirus illness often occurs in outbreaks, affecting large numbers of individuals, illustrated recently by well-publicized reports of gastroenteritis outbreaks on several recreational cruise ships and in settings such as hospitals and schools. Norovirus disease is clearly important in terms of medical costs and missed workdays, and accumulating data support its emerging recognition as important agents of diarrhea-related morbidity.

Haplotypes of Human Bitter Taste Receptor Genes

Bitter taste has evolved in mammals as a crucial, important warning signal against ingestion of poisonous or toxic compounds. However, many beneficial compounds are also bitter, and taste masking of bitter tasting pharmaceutical compounds is a billion dollar industry. The diversity of compounds that elicit bitter-taste sensations is very large and more than two dozen members of the T2R bitter taste receptor family have been identified. Individuals are now known to be genetically predisposed to respond or not to respond to the bitter taste of a number of substances.

Soluble Antigen-Based ELISA for the Detection of B. malayi Infections

The technology presented is a breakthrough in the diagnosis of lymphatic filariasis, specifically targeting the B. malayi pathogen. It encompasses a novel soluble antigen extract used in both IgG and IgG4-based ELISA tests, aimed at detecting the presence of the filarial infection. This innovation serves as a cornerstone for a CLIA-certified reference test, established and utilized in Dr. Nutman's laboratory since the late 1980s.

Recombinant NIE Antigen from Strongyloides stercoralis

Strongyloides stercoralis is an intestinal nematode endemic that affects an estimated 30 to 100 million people worldwide. Many of these individuals may be asymptomatic for decades. The present invention discloses a NIE recombinant antigen that can be used in improved assays and diagnostics for S. stercoralis infection. The NIE antigen is the only one that is non-cross-reactive with sera from humans with other related filaria infections. The NIE antigen can be utilized as a skin test antigen for immediate hypersensitivity as well as for use in ELISA or other assays.

Sensitive and Economic RNA Virus Detection Using a Novel RNA Preparation Method

DNA or RNA-based diagnostic tests for infectious diseases are critical in modern medicine. The current gold standard for COVID-19 detection is testing SARS-CoV-2 viral RNA by quantitative reverse transcription Polymerase Chain Reaction (RT-qPCR). This method involves patient sample collection with a nasopharyngeal swab, storage of the swab in a universal transport medium during transport to testing site, RNA extraction, and analysis of the extracted RNA sample.

Using Artificial Intelligence To Diagnose Uveitis

Summary: 
The National Eye Institute seeks research co-development partners and/or licensees for a deep learning algorithm that can identify retinal vasculitis using color fundus images.

Description of Technology: 
Uveitis is caused by inflammation in the eye that can cause pain and reduce vision. The rate of uveitis in the United States is 1 in every 200 people with eye-related irritation. Permanent symptoms such as vision loss can occur if untreated. Therefore, early detection is crucial. 

Innovative Antibody Conjugates for Targeted Therapy

This advanced technology introduces innovative antibody conjugates that redefine the possibilities of targeted therapy. By coupling therapeutic agents to engineered antibodies with highly specific binding sites, these conjugates deliver treatments directly to diseased cells while sparing healthy tissues. The result is a powerful increase in treatment efficacy, accompanied by a meaningful reduction in side effects.
