Researchers reveal the positive effects of exercise on the liver

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disorder worldwide, affecting as much as a quarter of humanity. It is characterized by fat accumulation in liver cells and may progress to inflammation, cirrhosis and liver failure.

Researchers discover two new ways to treat small cell lung tumors

Using samples of small cell lung tumors, a research team led by biologist Dr Silvia von Karstedt has discovered two new ways to induce tumor cell death. One of two subsets of tumor cells can be targeted by activating ferroptosis: iron-dependent cell death caused by oxidative stress

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.

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.

Stem cell therapy could help restore debilitating age-related muscle loss

As the name implies, induced pluripotent stem cells can become any type of cell in our body, and scientists have evidence that when they prompt them to become muscle progenitor cells they can help restore the sometimes debilitating muscle loss that happens with age.

Acute exposure of lung tissue to vape aerosol has lesser impact on gene expression than cigarette smoke

A new peer-reviewed study published in the journal Toxicological Research & Application shows acute exposure of a 3D human bronchial tissue model to e-cigarette aerosol has minimal impact on gene expression compared to smoke from combustible cigarettes.

Allogeneic adipose-derived stem cells can mitigate TBI-induced acute radiation syndrome

Nuclear power offers an efficient, reliable way to provide energy to large populations - as long as all goes well. Accidents involving nuclear reactors such as those that took place in 1986 at Chernobyl and at Fukushima Daiichi after the March 2011 tsunami raise major concerns about what happens if the worst occurs and large numbers of people are simultaneously exposed to high levels of radiation.
