This technology is directed to the discovery of specific microRNAs that target and downregulate enzymes within the cholesterol biosynthetic pathway and is currently being tested in vivo.

Scientists at NIAID have developed a method of treatment for virus-induced lung fibrosis using nebulized thrombin inhibitors. Since March 2020, the WHO estimates that 564 million people have been infected with SARS-CoV-2 world-wide. Lung fibrosis is a major factor associated with SARS-CoV-2 infections and can contribute to mortality. Additionally, severe SARS-CoV-2 cases can result in long-term pulmonary disease due to lung fibrosis. At present, attempts to treat lung fibrosis developed during a SARS-CoV-2 infection using intravenous heparin have been unsuccessful.

The invention pertains to software processes, additions, and docking approaches to Autodock Vina that speeds the rate and efficiency of analyzing ligand interactions with a receptor by cognate ligands and rewards conformations in the scoring algorithm for residue interactions that are based on the biological data. The score is multiplied by a weighting factor to control the degree of ligand-residue interactions that are considered. This multiplier is then added to the docking score for confirmation.

Zika virus (ZIKV) spreads to people primarily through bite by infected Aedes mosquitoes. ZIKV infection during pregnancy can cause stillbirths or affect the fetus by causing serious birth defects, such as microcephaly and other brain defects. Although uncommon, adults with ZIKV can also develop Guillain-Barre syndrome and other neurological disorders. According to the World Health Organization’s July 2019 report, a total of 87 countries and territories have had evidence of mosquito-borne transmission of ZIKV.

This CDC assay aims to lessen the anti-malarial drug counterfeiting epidemic by testing for the artemisinin-type drugs (the active compound), through the use of a simple, inexpensive colorimetric test. Poor quality and counterfeit drugs pose an immediate threat to public health and undermine malaria control efforts, resulting in resistant-parasites and invalidates effective compounds, i.e.

CDC scientists have developed synthetic/recombinant polypeptides that can be used for the creation of inexpensive, high-quality cysticercosis diagnostic assays. Taenia solium is a species of pathogenic tapeworm. Intestinal infection with this parasite is referred to as taeniasis and it is acquired by ingestion of T. solium cysticerci found in raw and undercooked pork, or food contaminated with human or porcine excrement. Many infections are asymptomatic, but infection may be characterized by insomnia, anorexia, abdominal pain and weight loss.

CDC researchers have developed improved Loop-Mediated Isothermal Amplification (LAMP) assays for the nucleic acid-based diagnosis of malaria in field settings. The approach employs Plasmodium genus-specific LAMP primers and a portable tube scanner to run the LAMP reaction and measure fluorescence signal (e.g., SYBR green) as a measure of DNA amplification in real time. Using this platform, the researchers were able to detect several different species of the human malaria parasites.

Micro-Screen is a CDC developed software program designed to capture images and archive and display a compiled image(s) from a portion of a microscope slide in real time. This program allows for the re-creation of larger images that are constructed from individual microscopic fields captured in up to five focal planes and two magnifications. This program may be especially useful for the creation of data archives for diagnostic and teaching purposes and for tracking histological changes during disease progression.

Within recent years, point-of-care (POC) testing has allowed for many individuals to be screened for and provided with HIV test results. It is critical to be able to accurately detect acute HIV infections as this is a stage where the risk of transmission is great. Additionally, early HIV detection could lead to less high-risk behavior, thereby reducing transmission. Currently, there are no rapid, cost-effective diagnostic tests sensitive enough to detect acute HIV-1 infections for the POC setting.

One of the problems with the development of current therapies for HIV infection is that the virus rapidly develops resistance to drugs such as reverse transcriptase (RT) inhibitors.
