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.
The formation of a cancer is proven to be a multi-stage, multi-mechanism process by animal and human studies.
More than half of all drugs given to patients work by targeting a particular type of "docking station," or receptor, found on body cells, to steer the cell's machinery toward healing an illness.
It used to be dogma that the brain was shut away from the actions of the immune system, shielded from the outside forces of nature.
The first quantitative study of protein complexes that transmit pheromone signals in living yeast cells sheds light on a crucial signalling process also found in humans.
In spring 2005 a large European research and training network was established to investigate the causes and implications of poor sleep from a medical as well as from a social point of view. This EU-financed sleep research project, “The biomedical and sociological effects of sleep restriction”, is coordinated by Dr. Tarja Porkka-Heiskanen (Stenberg) MD, PhD, at the University of Helsinki, Institute of Biomedicine.
Scientists at the MRC Laboratory of Molecular Biology (LMB) in Cambridge have obtained the first clear images of the proteins that relay vital messages to cells.
Scientists believe they have found an explanation for a puzzling and serious complication of West Nile virus infection.
When faced with adversity, some people succumb to debilitating psychological diseases including posttraumatic stress disorder and depression, while others are able to remain remarkably optimistic.
Insulin, long known as an important regulator of blood glucose levels, now has a newly appreciated role in the brain.
Genes responsible for our 24 hour body clock influence not only the timing of sleep, but also appear to be central to the actual restorative process of sleep, according to research published in the online open access journal BMC Neuroscience.
First it was an apple, now it is an aspirin a day that may keep the doctor away.
British researchers have discovered that a "nanna nap" or siesta in the afternoon can help lower the blood pressure and possibly ward off heart attacks.
A new analysis of randomized controlled trials evaluating probiotics in the treatment of irritable bowel syndrome (IBS) has found that Bifantis, Bifidobacterium infantis 35624, the sole ingredient in Align (manufactured by Procter & Gamble), is the only probiotic currently able to demonstrate significant improvement in IBS symptoms based upon a properly designed research study.
Where does the benefit lie in an afternoon nap? Is it in the nap itself--or in the anticipation of taking a snooze? Researchers in the United Kingdom have found that the time just before you fall asleep is where beneficial cardiovascular changes take place.
Based on POSSUM, a system suggested by some British scholars more than 10 years ago, a team led by Dr. Lian-An Ding has established the M-POSSUM evaluation system with the aim of improving the accuracy and effectiveness of the original system.
University of Cincinnati (UC) researchers have identified the neurotransmitter serotonin as the chemical responsible for inhibiting milk production and secretion in human mammary glands.
Individuals whose close relationships have negative aspects, such as conflict and adverse exchanges, appear to have an increased risk of heart disease than those with more positive close relationships, according to a report in the Oct. 8 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
Mario R. Capecchi, Ph.D., distinguished professor of human genetics and biology at the University of Utah's Eccles Institute of Human Genetics and a Howard Hughes Medical Institute investigator, has won the 2007 Nobel Prize in Physiology or Medicine.
Medical Research Council funded scientist Sir Martin Evans, has been awarded the Nobel Prize in Physiology or Medicine for 2007 alongside Mario R. Capecchi and Oliver Smithies for their discoveries of "principles for introducing specific gene modifications in mice by the use of embryonic stem cells".
A new study from the U.S. might be just the news you have been waiting for....that a diet rich in starch and sugar may leave you slimmer and healthier.
