Some kitchen cabinets can emit potentially harmful compounds

Probably the last place anyone would want to find airborne polychlorinated biphenyl compounds (PCBs) is in the kitchen, yet that’s exactly where scientists detected their presence, according to a new report in ACS’ journal Environmental Science & Technology. They say that the PCBs, which are widely considered carcinogenic, are unwanted byproducts of sealant breakdown in

Genetically altered broadly neutralizing antibodies protect monkeys from HIV-like virus: NIAID scientists report single dose elicited long-term protection

Two genetically modified broadly neutralizing antibodies (bNAbs) protected rhesus macaques from an HIV-like virus, report scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. After introducing genetic mutations into two potent HIV bNAbs, researchers prepared intravenous infusions of two bNAbs known as 3BNC117-LS and 10-1074-LS. Single

Structure of a protein complex related with cell survival revealed

A team from the Spanish National Cancer Research Centre (CNIO) has determined for the first time the high-resolution structure of a complex (R2TP) involved in key processes for cell survival and in diseases such as cancer. This achievement has been made possible by using high-resolution cryo-electron microscopy, a technique brought to the CNIO thanks to

Sensitive new assay detects hepatitis B infection in single liver cells and serum: Technique measuring the cccDNA marker may allow earlier detection of hepatocellular carcinoma in patients, reports The Journal of Molecular Diagnostics

Chronic hepatitis B virus (HBV) can progress to cirrhosis and hepatocellular carcinoma (HCC). A study published in The Journal of Molecular Diagnostics describes a new HBV assay that offers advantages over currently used methods because it has the capability to detect closed circular DNA (cccDNA) in serum, single cells, and preserved tissue samples. This assay

Genetic variant might be a better marker for heart disease

Researchers at the University of Cincinnati (UC) College of Medicine have found that a newly identified subset of a known genetic variant found primarily in individuals of South Asian descent may be a better marker for carriers of heart dysfunction in this population and that individuals with this genetic variant are more likely to develop

Clues for improved influenza vaccine design

Influenza vaccines that better target the influenza surface protein called neuraminidase (NA) could offer broad protection against various influenza virus strains and lessen the severity of illness, according to new research published in Cell. Current seasonal influenza vaccines mainly target a different, more abundant influenza surface protein called hemagglutinin (HA). However, because influenza vaccines offer

Common diabetes drug may also help with nicotine withdrawal

In a mouse study, a drug that has helped millions of people around the world manage their diabetes might also help people ready to kick their nicotine habits. In a report published this week in Proceedings of the National Academy of Sciences (PNAS), investigators say metformin, an inexpensive drug commonly used to treat patients with

Butterflies of the soul: Developmental origins of interneurons

Modern neuroscience, for all its complexity, can trace its roots directly to a series of pen-and-paper sketches rendered by Nobel laureate Santiago Ramón y Cajal in the late 19th and early 20th centuries. His observations and drawings exposed the previously hidden composition of the brain, revealing neuronal cell bodies and delicate projections that connect individual

Smartphone app performs better than traditional exam in cardiac assessment: Randomized clinical trial

A smartphone application using the phone’s camera function performed better than traditional physical examination to assess blood flow in a wrist artery for patients undergoing coronary angiography, according to a randomized trial published in CMAJ (Canadian Medical Association Journal). These findings highlight the potential of smartphone applications to help physicians make decisions at the bedside.
