Study suggests a role for the hypothalamus in genetic susceptibility to IBD

Using sophisticated 3D genomic mapping and integrating with public data resulting from genome-wide association studies, researchers at Children's Hospital of Philadelphia have found significant genetic correlations between inflammatory bowel disease and stress and depression.

Study finds low risk of adverse events from cardiac MRI contrast agents

Contrast agents used to improve views of the heart on MRI carry a very low risk of allergic reactions, vomiting and other acute adverse events, according to a large study from Europe published in Radiology: Cardiothoracic Imaging.

Intercellular communication pathway drives motivation to seek cocaine

In the October 28, 2020 issue of the Journal of Neuroscience, researchers from the Medical University of South Carolina and the National Institutes of Health describe how reminders of drug use can change specific brain cells responsible for motivation, increasing the desire to seek drugs.

Dietary restriction effective in reducing the odds of developing liver cancer from fatty liver

Liver cancer from too much fat accumulation in the liver has been increasing in many countries including Japan.

Protein tenascin-C plays a role in glaucoma by regulating inflammatory processes

Researchers at Ruhr-Universität Bochum have studied the role of the immune response in the development of glaucoma in mice.

Study sheds new light on cell division fidelity, can impact future regenerative medicine

Researchers discover that a specialized part of the chromosomes, essential for a correct cell division, is smaller and weaker in stem cells, when compared to the ones of differentiated cells.

New study may help combat loss of muscle mass associated with aging

Researchers at the University of São Paulo (USP) in Brazil have discovered that the muscle regeneration promoted by aerobic exercise is mediated by changes in oxygen consumption by satellite cells, also known as skeletal muscle stem cells.

Majority of people infected with mild-to-moderate COVID 19 mount robust antibody response

The vast majority of individuals infected with mild-to-moderate COVID 19 mount a robust antibody response that is relatively stable for at least five months, according to research conducted at the Icahn School of Medicine at Mount Sinai and published October 28, in the journal Science.

Researchers develop controllable system for mimicking biochemical reaction cascades in cells

Researchers at the University of Basel have developed a precisely controllable system for mimicking biochemical reaction cascades in cells.

Research program aims to thwart prion-like spread of tau pathology in Alzheimer’s disease

Tangles of misfolded tau proteins in the brain are closely associated with memory loss in patients with Alzheimer's disease. In order for this tau pathology to spread, the protein must interact with heparan sulfate, a sugar molecule found on the surface of neurons.

High-sugar diet can damage the gut’s protective mucus layer, lead to worse colitis

Mice fed diets high in sugar developed worse colitis, a type of inflammatory bowel disease (IBD), and researchers examining their large intestines found more of the bacteria that can damage the gut's protective mucus layer.

Physical stress caused by interruptions in workplace

ETH researchers have used an experiment in a simulated group office environment to show for the first time that the body produces more stress hormones when people are repeatedly interrupted at work.

Novel cardiac patch improves recovery from heart attack in rats and pigs

According to the American Heart Association, heart disease is the leading cause of death worldwide in recent years.

Sleep could be targeted to improve post-stroke recovery, study shows

Until today neurorehabilitation is the only approach that promotes recovery after stroke. Researchers at the Neurology Department of the University of Bern and Inselspital have provided first evidence that sleep could be targeted to improve post-stroke recovery.

Grant programs will provide $2.2 million to support biomedical research on healthy aging

The Glenn Foundation for Medical Research and the American Federation for Aging Research announce the 2020 recipients of three grant programs: the Glenn Foundation for Medical Research and AFAR Grants for Junior Faculty, the Glenn Foundation for Medical Research Postdoctoral Fellowships in Aging Research, and the Glenn Foundation for Medical Research Breakthroughs in Gerontology Awards.

Novel mechanism increases arterial diameter, allows increased inflow

Upon a heart infarct or stroke, rapid restoration of blood flow, and oxygen delivery to the hypoperfused regions is of eminent importance to prevent further damage to the heart or brain. Arterial diameter is a critical determinant of blood flow conductance.

Sleep deprivation can increase the rewarding properties of cocaine

Sleep deprivation may pave the way to cocaine addiction. Too-little sleep can increase the rewarding properties of cocaine, according to new research in mice published in eNeuro.

New technique could detect and map the progression of aggressive cancers

Using a new technique, a team of McGill University researchers has found tiny and previously undetectable 'hot spots' of extremely high stiffness inside aggressive and invasive breast cancer tumors.

Scientists use experimental approach to identify genes and interactions

A phage is a virus that invades a bacterial cell. While harmless to human cells, phages are potentially deadly to bacteria since many phages enter a cell in order to hijack its machinery in order to reproduce itself, thus destroying the cell.

Researchers identify physiological mechanism that maintains regenerative capacity of muscle stem cells

Researchers at UPF, the National Centre for Cardiovascular Research, ICREA and Ciberned have identified a physiological mechanism that maintains the regenerative capacity of muscle stem cells, and surprisingly resists the passage of time far more than expected, until geriatric age.
