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.
Bacteria, often synonymous with infection and disease, may have an unfair reputation. Research indicates there are as many, if not more, bacterial cells in our bodies as human cells, meaning they play an important role in our physiology.
New research suggests that the relationship between physical and brain fitness varies in older adults by virtue of their sex. The study is published ahead of print in the Journal of Applied Physiology.
Think state-of-the-art shoes, performance diets and well-thought-out racing strategies are only for elite runners?
It's well-known that exercise improves health, but understanding how it makes you healthier on a molecular level is the question researchers at Joslin Diabetes Center are answering.
University of Houston and Methodist Hospital researchers are reporting in Scientific Reports that the best way to train surgeons is to remove the stress of residency programs and make surgery a hobby.
Mosquitoes can hear over distances much greater than anyone suspected, according to researchers at Cornell and Binghamton University.
New research on how cancer mutations influence a certain type of receptor on the cell membrane opens the way for the development of tailored drugs for certain cancers, such as rectal cancer and lung cancer.
When a person takes a puff on a cigarette, nicotine floods into the brain, latching onto receptors on the surface of neurons and producing feelings of happiness. But nicotine does not simply stay on the surface of cells--the drug actually permeates into neural cells and alters them from the inside out.
Despite popular belief, drinking beer before wine does not reduce the severity of veisalgia, otherwise known as a hangover, the following day.
An international multidisciplinary study initiated by Melbourne scientists has shown a link between prostate cancer and the uptake of fatty acids by cancer cells.
To unravel the mysterious mechanisms of drug potency for the treatment of cardiac arrhythmias, a group of researchers at UC Davis have developed novel simulations that provide insights on vital atomic-scale drug-cardiac cells interactions.
The benefits of exercise are widely known but kinesiologists at McMaster University have for the first time found that physical activity may help fight depression in seniors by stimulating muscle-generated mood boosters.
A team of researchers from the University of Delaware has received nearly $200,000 in start-up funding to develop a motorized ankle foot device for children with cerebral palsy that includes a novel artificial muscle.
Researchers have combined the largest description of ST3GAL5 deficiency using detailed natural history data from 104 individuals of Amish ancestry born between 1986 and 2017 with a definite or probable diagnosis of ST3GAL5 deficiency.
A research team has described the first case of a patient affected by dysfunctions in a nucleoside transporter of the SLC28 gene family, which brings a set of genes which were not related to human pathologies in the scientific bibliography so far.
Research in mice suggests that fermentation of flaxseed fibers in the gut changes the microbiota to improve metabolic health and protect against diet-induced obesity.
For reasons that are unclear, schizophrenia patients have fewer connections between the neurons in the brain. Researchers at Karolinska Institutet, Sweden, and Massachusetts General Hospital, USA, have now succeeded in creating human cell models that show that there is an excessive degradation of connections in the brain of these patients, and they have been able to link this to a genetic risk variant for the disease.
During a study spanning nearly a decade, researchers at The Ohio State University College of Medicine, Houston Methodist Research Institute and Houston Methodist Cancer Center have linked the protein clusterin - for the first time -- to many different facets of cardiometabolic syndrome risk through its actions in the liver.
The American Thoracic Society has developed a new clinical practice guideline for home oxygen therapy for children. The guideline appears in the Feb. 1 edition of the Society's American Journal of Respiratory and Critical Care Medicine.
The American Gastroenterological Association (AGA) has announced the 2019 recipients of the annual recognition awards, given in honor of outstanding contributions and achievements in gastroenterology.
