This invention is a potential subcutaneous or intramuscular progestin-only, injectable contraceptive for women. Forty-five percent (45%) of pregnancies in the United States are unintended. In this group, one-third of reproductive age women are obese – increasing the risk of diabetes, hypertension and venous thromboembolism (VTE). All these are conditions for which most hormonal methods are contraindicated. Thus, additional safe and effective injectable contraceptive options are needed.

The options for male contraceptives are limited. Research is ongoing to develop a male contraceptive based on hormonal activity. Testosterone is one of the hormones necessary in producing sperm.  Testosterone is absolutely required as a hormone for male fertility. Derivatives of testosterone for male contraceptives currently in clinical trials are associated with estrogenic deficiency. This deficiency can cause several issues including, but not limited to, bone density loss, risk of obesity, cardiovascular disease, and/or ineffective carbohydrate or lipid metabolism. 

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. 

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.

The culture of mouse embryos ex utero and continuous monitoring and imaging of embryos as they develop have applications in drug testing, genetic studies, and basic research on embryonic development. However, the embryo culture systems currently available for post-implantation embryos include rolling bottle culture systems, which do not permit imaging of the developing embryos and do not support the long-term survival and development of embryos ex utero.

It is well documented in literature that activation of RXFP1 by relaxin induces: 1) up-regulation of the endothelin system which leads to vasodilation; 2) extracellular matrix remodeling through regulation of collagen deposition, cell invasiveness, proliferation, and overall tissue homeostasis; 3) a moderation of inflammation by reducing levels of inflammatory cytokines, such as TNF-a and TGF-b; and 4) angiogenesis by activating transcription of VEGF.

This technology includes a new class of nanobody–antiviral peptide conjugates that block HIV from infecting human CD4⁺ T-cells, positioning them for future therapeutic and prophylactic use. Nanobodies—single-domain antibody fragments—guide the drug to the virus’s docking site and impede receptor binding, while the linked peptide halts the membrane-fusion step, creating a one-two punch against viral entry.
