Handwipe Disclosing Method for Detecting the Presence of Lead

Lead (Pb) exposure can cause serious health concerns including abdominal pain, headaches, loss of appetite, memory loss, weakness, and other symptoms. Lead residues on human skin, especially on the hands of workers can be a significant health risk since such residues may be ingested during normal activities (e.g. eating, drinking, and smoking). A key component to reducing lead exposure is being able to identify areas of lead contamination.

Novel VAR2CSA Immunogens and Methods of Use Thereof

The invention provides immunogen polypeptides comprising fragments of VAR2CSA protein expressed by P. falciparum as potential second-generation placental malaria vaccine candidates. VAR2CSA is the leading antigen target for a placental malaria vaccine, where associated antibody titers are correlated with protection. Aspects of the inventive immunogen polypeptides comprise all or portions of the chondroitin sulfate A (CSA) binding regions of VAR2CSA, as identified by a structural study of VAR2CSA conducted by the inventors, that possess great sequence conservation among P.

Novel Compositions of Matter Comprising Stabilized Coronavirus Antigens and Their Use

Using a computational design methodology, SARS-CoV-2 spike proteins containing engineered amino acid changes to the receptor binding domain (RBD) were designed. These engineered spike proteins improved the immune response upon immunization of animals. An engineered RBD was also expressed at greater yield, had increased temperature stability, and improved the immune response upon immunization of animals. Specifically, the disclosed RBD designs can be produced approximately 7 times more efficiently than the native sequence, facilitating vaccine manufacturing on a global scale.

New Cholera Vaccine and Method for Conjugating Bacterial Polysaccharides to Proteins

A new conjugate vaccine for cholera has been developed. The invention includes a new method to conjugate the O-specific polysaccharide-core part of the bacterial lipopolysaccharide and protein subcomponents. Conventional technology has entailed chemical treatment of both components to introduce linkers, which made them amenable for covalent linking. The new method simplifies production by utilizing squaric acid chemistry for conjugating the free amine-containing species (e.g. polysaccharides) directly to amine-containing species (e.g.

Human Monoclonal and Bispecific Antibodies Targeting SARS-CoV-2 Coronavirus

SARS-CoV-2 is a virus of the Coronavirus family that has emerged as a major public health concern. The first cases of SARS-CoV-2 were reported in China and rapidly spread worldwide leading to a global pandemic. The highest morbidity and mortality have been reported in the elderly and immunocompromised. Antibody therapeutics have great importance for advanced cases of SARS-CoV-2 where a vaccine would not be effective and may be more effective than a vaccine in certain high-risk populations.

Pre-Biotic Formulation of Topical Chemicals for Use on Human Skin

Atopic dermatitis (AD) is a common, recurrent, chronic inflammatory skin disease that is a cause of considerable economic and social burden. It is one of the most prevalent skin disorders, affecting ~25% of children in developed and developing countries and is expected to continue to escalate. This increased rate of incidence has changed the focus of research on AD toward epidemiology, prevention, and treatment.

Directed Acetylation of Cytidine in Cellular mRNA through Engineered snoRNA Adapters for the Treatment of Haploinsufficiencies

Summary: 

The National Cancer Institute (NCI) seeks research co-development partners and/or licensees for engineered chimeric snoRNA guides that recruit NAT10 to a specific target and cause directed acetylation of the target. They could be used to treat haploinsufficiency-associated disorders or diseases.

Combined RNA and DNA Vaccination Strategy for Improving the Vaccine Immune Response

The development of an effective HIV vaccine has been ongoing. HIV sequence diversity and immunodominance are major obstacles in the design of an effective vaccine. Researchers at the National Cancer Institute (NCI) developed a novel vaccine strategy combining both DNA and mRNA vaccination to induce an effective immune response. This combination strategy could also be used to develop vaccines against cancer or other infectious diseases (ex. SARS-CoV-2). 

Methods of Predicting Patient Treatment Response and Resistance via Single-Cell Transcriptomics of Their Tumors

Tailoring the best treatments to cancer patients remains a highly important endeavor in the oncology field. However, personalized treatment courses are challenging to determine, and technologies or methods that can successfully be employed for precision oncology are lacking.
