A peptide hydrogel for use in vascular anastomosis

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.

Photoactivatable Lipid-based Nanoparticles as a Vehicle for Dual Agent Delivery

The invention relates to novel lipid-based nanoparticles (liposomes) for use in targeted, on demand and on site drug delivery. The particles include a wall surrounding a cavity, wherein the wall is comprised of:

  1. A lipid bilayer comprising 1,2-bis(tricosa-10,12-diynoyl)-sn-glycero-3-phosphocholine (DC8,9PC), dipalmitoylphosphatidylcholine (DPPC), and 1,2-distearoyl-sn-glycero-3-

phosphoethanolamine-N-[methoxy(polyethylene glycol)-2000] (DSPE-PEG2000), and

Devices for Improved Tissue Cryopreservation and Recovery

Problem: Cryopreservation is a process where living biological materials like cells, tissues, and cell therapies (which are susceptible to damage caused by unregulated chemical kinetics) are preserved by cooling to very low temperatures in the presence of specific cryopreservation media that protects the biological material from damage. In order to be used, the biological material ideally should be thawed in a controlled manner that minimizes damage and desirably brings the material back to a viable state.

Nitric Oxide-Releasing Polymers for Wound Healing

 A number of factors can play a detrimental role in the process of wound healing such as poor nutritional status, smoking, various drugs, cancer, and diabetes.  Wound healing impairment is a challenging clinical problem with no efficacious treatments currently available.  Nitric oxide (NO) has been shown to play a role in the process of wound healing by promoting both the proliferative and remodeling phases of healing. 

Generation of Artificial Mutation Controls for Diagnostic Testing

This technology relates to a method of generating artificial compositions that can be used as positive controls in a genetic testing assay, such as a diagnostic assay for a particular genetic disease. Such controls can be used to confirm the presence or absence of a particular genetic mutation. The lack of easily accessible, validated mutant controls has proven to be a major obstacle to the advancement of clinical molecular genetic testing, validation, quality control (QC), quality assurance (QA), and required proficiency testing.

Method of Producing Immortalized Primary Human Keratinocytes for HPV Investigation, Testing of Therapeutics, and Skin Graft Generation

One of the major limitations of using cultured keratinocytes for research studies is that primary keratinocytes senesce after a few passages. Keratinocytes from specific anatomical sites are also difficult to culture. Scientists at the NIH have demonstrated that primary keratinocytes, from several anatomical sites, when treated with a small-molecule inhibitor of the ROCK protein maintain a proliferative state and become immortal without genetic modification to the cells.

Next-Generation 5-HT-2B Serotonin-Receptor Antagonists for Anti-Fibrotic & Cardiopulmonary Therapy

This technology includes a family of small-molecule antagonists that selectively block the 5-HT2B serotonin receptor—an upstream driver of tissue-remodeling—to address fibrotic, cardiopulmonary and related disorders. Built on a conformationally-locked “(N)-methanocarba” nucleoside scaffold, the compounds show nanomolar potency, >30–400-fold selectivity over the closely related 5-HT2C receptor, and favorable oral bioavailability in rodents.

First in class Small Molecule Agonists of the mammalian Relaxin family receptor 1 (RXFP1) and use in treatment of cancer, fibrotic, and vascular disorders (HHS Ref No. E-145-2024-0-US-02)

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.

Selective A3 Adenosine Receptor Agonists for the Treatment of Chronic Neuropathic Pain and Other Conditions

This technology includes the creation and use of A3 adenosine receptor (A3AR)-selective agonists for treating chemotherapy-induced peripheral neuropathy, chronic neuropathic pain, rheumatoid arthritis, psoriasis, and other conditions. A3 receptors for adenosine are found in most cells and endogenous activation of the A3 receptors can result in apoptosis, thereby relieving the inflammation or targeting a tumor. A3AR agonists have been a promising strategy for the treatment of various diseases.
