This technology includes a novel advancement in developing vaccines targeting norovirus, tailored specifically for a more robust and effective response. It centers around an improved version of Virus-Like Particles (VLPs) uniquely engineered for greater stability and efficacy. These enhanced VLPs are designed to remain intact even when faced with the body's immune responses, overcoming a key limitation of previous vaccine designs.

The baculovirus-based protein expression system has gained increased prominence as a method for expressing recombinant proteins that are used in a wide range of biomedical applications. An important step in the use of this system is the ability to determine the virus infectious titer, i.e., the number of active baculovirus particles produced during an infection of the insect host cell.

Baculoviruses have been used for decades to produce proteins in insect cell hosts. Current systems for generating recombinant baculovirus have several shortcomings which prevent their easy use in high-throughput applications. 

Small molecule fluorescent probes are important tools in diagnostic medicine. Existing far-red and near-IR cyanine fluorophores (e.g. Cy5, Alexa 647, Cy7, ICG) are active in the far-red and near-range, but these agents suffer from modest quantum yields (brightness) which limit wide utility. It has been reported that the limited brightness of these fluorophores is due to an excited-state C-C rotation pathway.

In collaboration with surgery specialists from Johns Hopkins University, researchers at the National Cancer Institute (NCI) developed novel hydrogel compositions and methods of using them in the microsurgical suturing of blood vessels, which is particularly beneficial for surgeons in whole tissue transplant procedures. The lead candidate electropositive hydrogels, called APC1, was demonstrated in anastomosis mice models to be well tolerated, biocompatible, and non-toxic.

Ultrasound-based cancer screening and biopsy imaging technologies are a clinical need. Ultrasound based biopsy imaging can provide a real-time modality for lower cost that is comparable to, or complimentary to MRI imaging.  This technology may enable more accurate, less costly and more accessible cancer screening.

GISTs are one of the most common sarcomas of the gastrointestinal tract with an estimated 5,000-10,000 new cases in the U.S. reported each year. GISTs affect mainly pediatric and young adult patients, and respond poorly to current therapies. Paragangliomas are rare neuroendocrine neoplasms that develop primarily in the abdomen.

The National Institute on Drug Abuse's Medications Discovery Research Branch is seeking statements of capability or interest from parties interested in collaborative research to further develop, evaluate, or commercialize 4-phenylpiperazine derivatives as dopamine D3 selective ligands.

Norovirus is a leading cause of vomiting, diarrhea, and foodborne illness worldwide, with 700 million cases and 200,000 deaths occurring each year. Despite decades of work in the field, there are no preventive or therapeutic strategies specifically approved for even the most prevalent forms of human norovirus (i.e., GI, GII genogroups), which are highly contagious and carry an increased risk of severe complications in children, older adults, and those with immunocompromising conditions.
