Human physiology is the science of the mechanical, physical, and biochemical functions of humans in good health, their organs, and the cells of which they are composed. The principal level of focus of physiology is at the level of organs and systems. Most aspects of human physiology are closely homologous to corresponding aspects of animal physiology, and animal experimentation has provided much of the foundation of physiological knowledge. Anatomy and physiology are closely related fields of study: anatomy, the study of form, and physiology, the study of function, are intrinsically tied and are studied in tandem as part of a medical curriculum.
New guidance from exercise oncology experts recommend systematic use of an "exercise prescription" by health care workers and fitness professionals in designing and delivering exercise programs that aim to lower the risk of developing certain cancers and best meet the needs, preferences and abilities of people with cancer.
How long does it take an athlete to recover from a concussion? New research has found an athlete's brain may still not be fully recovered one year after being allowed to return to play.
Squids, octopuses, cuttlefish, amphibians, and chameleon lizards are among the animals that can change the color of their skin in a blink of an eye. They have photoreceptors in their skin that operate independently of their brain. The photoreceptors are part of a family of proteins known as opsins.
The brain's neural activity-;long implicated in disorders ranging from dementia to epilepsy-;also plays a role in human aging and life span, according to research led by scientists in the Blavatnik Institute at Harvard Medical School.
A new study examining the role that star-shaped brain cells called astrocytes play in Huntington's disease has identified a potential strategy that may halt the disease and repair some of the damage it causes.
Hyperbaric oxygen therapy can relieve self-reported symptoms and side-effects of radiotherapy against cancer in the pelvic region, a study shows. After 30-40 sessions in a hyperbaric chamber, many patients experienced reductions in bleeding, urinary incontinence, and pain alike.
A recent review of research, conducted by an international group of experts led by the University of British Columbia, has resulted in the development of new exercise guidelines for cancer survivors.
Rapid communication of neurons in the brain, as well as the ability to learn, fundamentally rely on neurotransmitter receptors located in the contact sites of neurons, the synapses. The most important receptors in the mammalian brain are glutamate receptors of the AMPA-type that generate the electrical signal required for fast communication between neurons.
It's well known that exercise is good for preventing and treating many forms of heart disease, but less commonly known are the benefits of physical activity for people living with and beyond cancer.
A team led by scientists at the University of Pennsylvania and University of Georgia provides thousands of researchers around the world with access to the Eukaryotic Pathogen Genomics Database (EuPathDB.org), a collection of resources for analyzing large-scale datasets associated with microbial pathogens.
A study from McMaster University has found a potential mechanism explaining why some people who take drugs to lower their cholesterol develop sore, aching muscles.
A global panel of exercise oncology experts today published new guidance recommending the systematic use of an “exercise prescription” to help cancer patients cope with treatment side effects and lower the risk of developing certain cancers.
When the adrenal gland produces too much aldosterone, this often leads to high blood pressure and kidney damage (hyperaldosteronism). It has only recently emerged that several patients harbor a mutation in the gene for the ClC-2 chloride channel.
Pediatric anesthesiologists, like Dr. Guelay Bilen-Rosas at UW Health, have long been concerned by how difficult it is to detect breathing problems among young patients during anesthesia.
When trying to get pregnant, couples often change their lifestyles, going on crash diets or taking up stricter exercise regimens. New research, done on mice, suggests that men might be best off avoiding crash diets, as it may affect the heart health of their offspring.
The waning effectiveness of drugs over time continues to be a major challenge in treating diseases, including asthma.
Due to strain-specific behavioral idiosyncrasies, inbred mouse strains are suboptimal research models for behavioral aging studies.
For all the attention the human microbiome has been getting over the last few years, one aspect of such research rarely makes headlines: the difficulty of observing how it changes over time in response to various stimuli.
New research suggests a vaccine that blocks a digestive hormone may slow the spread of pancreatic cancer, potentially increasing survival rates. The study, published ahead of print in the American Journal of Physiology—Gastrointestinal and Liver Physiology, was chosen as an APSselect article for October.
Aging is an inevitable and a normal process of life. As people grow older, they lose muscle mass caused by age-related sarcopenia. In older adults, the maintenance of muscle mass and strength contribute to mobility which impacts quality of life. One of the reasons why older adults become frail is because of age-related muscle weakness.
