Red blood cells are the most abundant cell type in blood, carrying oxygen throughout the human body. In blood circulation, they repetitively encounter various levels of oxygen tension. Hypoxia, a low oxygen tension condition, is a very common micro-environmental factor in physiological processes of blood circulation and various pathological processes such as cancer, chronic … [Read more...]

How HIV Infection Shrinks the Brain’s White Matter
It's long been known that people living with HIV experience a loss of white matter in their brains. As opposed to "gray matter," which is composed of the cell bodies of neurons, white matter is made up of a fatty substance called myelin that coats neurons, offering protection and helping them transmit signals quickly and efficiently. A reduction in white matter is associated … [Read more...]
Evidence Supports COVID-19 Hearing Loss Link, Say Scientists
Hearing loss and other auditory problems are strongly associated with Covid-19 according to a systematic review of research evidence led by University of Manchester and NIHR Manchester Biomedical Research Centre (BRC) scientists.

Life changes influence physical activity
Life changes influence the amount of physical activity in a person, according to a recent study by the University of Jyväskylä. The birth of children and a change of residence, marital status and place of work all influence the number of steps of men and women in different ways. For women, having children, getting a job and moving from town to the countryside reduce everyday … [Read more...]
Dental experts discover biological imbalance is the link between gum and kidney disease
An imbalance of the body's oxygen producing free radicals and its antioxidant cells could be the reason why gum disease and chronic kidney disease affect each other, a new study led by the University of Birmingham has found. Periodontitis -- or gum disease -- is a common, inflammatory disease which causes bleeding gums, wobbly or drifting teeth and can eventually result in … [Read more...]

Wording of vaccination messages influences behavior
When it comes to vaccination, words matter as do perceptions of what is normal behavior. An experiment by Washington State University researchers revealed that relatively small differences in messages influenced people's attitudes about the human papillomavirus or HPV vaccine, which has been shown to help prevent cancer. Young adult subjects in the study recently published … [Read more...]
Inexpensive retinal diagnostics via smartphone

Dementia gene raises risk of severe COVID-19
Having a faulty gene linked to dementia doubles the risk of developing severe COVID-19, according to a large-scale study. Researchers at the University of Exeter Medical School and the University of Connecticut School of Medicine analysed data from the UK Biobank, and found high risk of severe COVID-19 infection among European ancestry participants who carry two faulty … [Read more...]
Tiny RNA that should attack coronavirus diminish with age, disease
A group of tiny RNA that should attack the virus causing COVID-19 when it tries to infect the body are diminished with age and chronic health problems, a decrease that likely helps explain why older individuals and those with preexisting medical conditions are vulnerable populations, investigators report. MicroRNAs play a big role in our body in controlling gene expression, … [Read more...]
Everything is not fine: Kids can tell when parents suppress their stress
Stress is common in a family setting, especially when people are spending so much time together under stay-at-home measures meant to slow the spread of COVID-19. New research finds that parents suppressing feelings of stress around their kids can actually transmit those feelings to the children. In a paper published in Journal of Family Psychology, Sara Waters, assistant … [Read more...]
Genetics linked to childhood emotional, social and psychiatric problems

How and where to allocate stockpiled ventilators during a pandemic
Key factors must be taken into account in determining the need for and allocation of scarce ventilators during a severe pandemic, especially one causing respiratory illness. Strategies to help state and local planners in allocating stockpiled ventilators to healthcare facilities, including pre-pandemic actions and actions to be taken during the pandemic, are detailed in a … [Read more...]
Study reveals how long COVID-19 remains infectious on cardboard, metal and plastic
The virus that causes COVID-19 remains for several hours to days on surfaces and in aerosols, a new study published in the New England Journal of Medicine found. The study suggests that people may acquire the coronavirus through the air and after touching contaminated objects. Scientists discovered the virus is detectable for up to three hours in aerosols, up to four hours … [Read more...]
Individual response to COVID-19 ‘as important’ as government action
How individuals respond to government advice on preventing the spread of COVID-19 will be at least as important, if not more important, than government action, according to a new commentary from researchers at the University of Oxford and Imperial College London in the UK, and Utrecht University and the National Institute for Public Health and the Environment in the … [Read more...]

Hookah Smoke may be Associated with Increased Risk of Blood Clots
For the first time, in a study conducted in mice, researchers found that tobacco smoke from a hookah caused blood to function abnormally and be more likely to clot and quickly form blood clots, which can increase the risk of heart attack or stroke, according to new research published today in the American Heart Association's journal Arteriosclerosis, Thrombosis and Vascular … [Read more...]
Data-driven definition of unhealthy yet pervasive ‘hyper-palatable’ foods
A popular U.S. brand of potato chips once promoted itself with the slogan, "betcha can't eat just one!" Maybe that's because potato chips, like so many foods in the American diet, can pack a mix of ingredients apt to light up people's brain-reward neural circuitry and overpower mechanisms that are supposed to signal when we've had enough to eat. Researchers call this … [Read more...]
Looking inside the body with indirect light
Light provides all our visual information, but it reaches our eyes in different ways. Direct light comes unperturbed, coming straight from the source, whereas indirect light bounces off different surfaces, such as walls or ceilings, before entering our eyes. Extracting information from these two pathways has significant implications in diagnostic imaging and other applications. … [Read more...]
