Drinking flavanol-rich cocoa could protect from mental stress-induced cardiovascular events

Increased consumption of flavanols - a group of molecules occurring naturally in fruit and vegetables - could protect people from mental stress-induced cardiovascular events such as stroke, heart disease and thrombosis, according to new research.

Male fetuses impair the maternal and placental immune response to SARS-CoV-2 infection in pregnancy, finds study

The ongoing COVID-19 pandemic, caused by SARS-CoV-2, is now established to be more likely to lead to symptomatic and serious illness in males relative to females. This may extend as far back as pregnancy, suggests a recent study.

NIAID researchers identify key player in the immune response to SARS-CoV-2

When variants of SARS-CoV-2 (the virus that causes COVID-19) emerged in late 2020, concern arose that they might elude protective immune responses generated by prior infection or vaccination, potentially making re-infection more likely or vaccination less effective.

New study may lead to GRK5-based therapies to prevent heart failure

The human heart works under high demand, constantly pumping oxygen-rich blood through the body. When faced with disease, however, fulfilling this demand can become increasingly difficult and harmful.

Researchers explore motivations and challenges of Indonesian women pursuing a career in conservation sciences

In a new study published in Conservation Science and Practice, researchers at the University of Maryland (UMD) partnered with Indonesian experts to explore the motivations and challenges of women pursuing a career in conservation sciences in Indonesia.

Combination of two existing drugs can kill cancer cells

Preclinical research from VCU Massey Cancer Center published recently in the Proceedings of the National Academy of Sciences shows that the combination of two existing drugs can exploit the metabolic "hunger" of a particularly aggressive type of neuroblastoma to kill cancer cells without inflicting too much collateral damage to healthy tissue.

Stress and boredom may have contributed to increased cigarette use during the pandemic

Stress, increased free time and feelings of boredom may have contributed to an increase in the number of cigarettes smoked per day during the early months of the COVID-19 pandemic by nearly a third of surveyed Pennsylvania smokers.

Neuroscape Psychedelics Division at UCSF to advance psychedelics research and therapies

Psychedelics research in support of brain health is getting a major boost this month with the formation of the Neuroscape Psychedelics Division at the University of California, San Francisco.

Research consortium identifies cell stress mechanisms for chronic inflammatory liver disease

Primary sclerosing cholangitis (PSC) is a rare, chronic, inflammatory disease of the bile ducts and is difficult to treat, since its causes have not yet been adequately researched.

Study reveals a novel mechanism of circulatory response to stressful events

Researchers from the University of Tsukuba discover a novel mechanism by which the brain regulates the cardiovascular system in response to stress.

Arginine methylation important in SARS-CoV-2 viral replication

Researchers show that methylation of arginine in the virus nucleocapsid protein controls the protein's functions and plays a role in the life cycle of the SARS-CoV-2 virus.

GlyNAC could improve many age-associated defects in older humans

A pilot human clinical trial conducted by researchers at Baylor College of Medicine reveals that supplementation with GlyNAC - a combination of glycine and N-acetylcysteine as precursors of the natural antioxidant glutathione - could improve many age-associated defects in older humans to improve muscle strength and cognition, and promote healthy aging.

Intelligent near-infrared vein scanner may make blood draws much easier

Researchers from Skoltech have developed an early prototype of a medical imaging system that uses neural networks to analyze near-infrared images of veins and project a venous pattern onto a patient's body - this may make blood draws much easier and less of a nuisance for patients with difficult access to veins.

Researchers examine circRNAs encoded by MERS-CoV, SARS-CoV-1 and SARS-CoV-2

New research published in Briefings in Bioinformaticsm has identified thousands of circRNAs in Betacoronaviruses, including MERS-CoV, SARS-CoV-1, and SARS-CoV-2, from the RNA-sequencing data of viral infections. These coronaviruses have a similar genomic structure with a diverse circRNA coding ability. Researchers have also systematically characterized circRNAs in coronaviruses, with regard to their size, sequence feature, expressions, genome, location preference, and functions. This opens the door to further explore and understand the mode of action of individual circRNAs in coronaviruses.

New study uncovers potential therapeutic target for lupus

A recent study published in JCI found that a neutrophil's endoplasmic reticulum, the organelle that normally makes proteins in the cell, becomes stressed in the autoimmune disorder lupus.
