UrduA study in mice found that intermittent fasting brought benefits beyond weight loss, suggesting it could help the body better process glucose and reduce age-related declines in intestinal function. Researchers will present their work this week at the American Physiology Summit.

Acetaminophen May Be Less Heart-safe than Previously Thought
The common painkiller acetaminophen was found to alter proteins in the heart tissue when used regularly at moderate doses, according to a new study conducted in mice. Researchers will present their work this week at the American Physiology Summit in Long Beach, California.
Study Details Toxic Elements Found in Stranded Whales, Dolphins Over 15 Years
Researchers evaluated the prevalence, concentration and tissue distribution of essential and non-essential trace elements, including heavy metal toxicants in tissue (blubber, kidney, liver, skeletal muscle, skin) and fecal samples. Findings reveal how toxicant levels relate to their sex, breed, age and other demographic factors.
New study reveals why defense against brain corrosion declines in people with Alzheimer’s disease
A new study by researchers at Case Western Reserve University revealed that the progression of Alzheimer’s disease (AD) can be slowed by suppressing a specific protein in the brain that causes corrosion.
Pulmonary and neurological health effects associated with exposure to representative composite manufacturing emissions and corresponding alterations in circulating metabolite profiles
Abstract Cured-in-place pipe (CIPP) technology is increasingly being utilized to repair aging and damaged pipes, however, there are concerns associated with the public health hazards of emissions. CIPP installation involves the manufacture of a new plastic composite pipe at the…
Vaping CBD can increase susceptibility to respiratory infection, says Roswell Park study author

Vaping CBD Causes More Severe Lung Damage Than Vaping Nicotine, Roswell Park Study Shows
Vaping cannabidiol (CBD), a compound found in marijuana, leads to more severe lung damage than vaping nicotine, according to a study out of Roswell Park Comprehensive Cancer Center. Until now, research on the health effects of vaping, or using e-cigarettes, has focused almost exclusively on vaping nicotine as opposed to CBD. Previous research has documented the effects of smoking cannabis, but the effects of vaping cannabinoids such as CBD were not previously known.
How COVID-19 Can Impact the Heart
ROCKVILLE, MD – COVID-19 infections can cause potentially life-threatening heart issues. Studies suggest that people with COVID-19 are 55% more likely to suffer a major adverse cardiovascular event, including heart attack, stroke and death, than those without COVID-19. They’re also more likely to have other heart issues, like arrhythmias (abnormal heart rhythms) and myocarditis (inflammation of the heart muscle).
Study Explores Effects of Resistance Training in Older Adults at the Cellular Level
Aging and related diseases are associated with alterations in oxidative status and low-grade inflammation, as well as a decreased endoplasmic reticulum (ER) unfolded protein response (UPR). UPR is a functional mechanism by which cells attempt to protect themselves against ER stress. Researchers analyzed these proteins in peripheral blood mononuclear cells of elderly subjects and used computer simulation to predict the key proteins associated with these biomolecules underlying physiological adaptations to exercise. They collected blood samples about five to six days before and after the training period and analyzed various oxidative stress biomarkers in peripheral blood mononuclear cells. The study takes research one step further in helping to elucidate the benefits of exercise in this population.
Kidney Injury Increases Oxidative Stress, Depletes Energy Production in Lungs
Article title: Lung metabolomics after ischemic acute kidney injury reveals increased oxidative stress, altered energy production and ATP depletion Authors: Sophia L. Ambruso, Hyo-Wook Gil, Benjamin Fox, Bryan Park, Christopher Altmann, Rushita A. Bagchi, Peter R. Baker II, Julie A.…
Differences in human, mouse brain cells have important implications for disease research
A UCLA-led study comparing brain cells known as astrocytes in humans and mice found that mouse astrocytes are more resilient to oxidative stress, a damaging imbalance that is a mechanism behind many neurological disorders.
Uncovering a Link Between Inflammation and Heart Disease
In a new study in Circulation, researchers from Tufts University School of Medicine in collaboration with investigators at Vanderbilt University and Tufts Medical Center reveal a mechanism that is activating T cells, a type of immune cell, and causing inflammation in the heart.
UTEP Researchers Develop Nanohybrid Vehicle to Optimally Deliver Drugs Into the Human Body
The researchers discovered that encapsulating ellagic acid in chitosan, a sugar, reduces its inherent cytotoxicity while enhancing its anti-oxidant properties. The chitosan shell, which makes up the hard outer skeleton of shellfish, also permits EA delivery via a rapid burst phase and a relatively slow phase.
Two Rutgers Professors Named Fellows of AAAS
Two Rutgers professors have been named fellows of the American Association for the Advancement of Science (AAAS) this year, an honor awarded to AAAS members by their peers. They join 441 other AAAS members named new fellows because of their scientifically or socially distinguished efforts to advance science or its applications. The fellows will be presented an official certificate and a gold and blue (representing science and engineering, respectively) rosette pin on Feb. 15 at the AAAS Fellows Forum during the 2020 AAAS Annual Meeting in Seattle, Washington.
