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.
A new study using ovarian cancer cell lines shows promise in treating the deadly disease by combining the chemotherapy drug cisplatin with an aspirin-like compound to make recurrent cancer cells less resistant to the chemotherapy.
Indiana University School of Medicine scientists have begun a unique clinical trial using stem cell injections as a treatment that could offer hope to tens of thousands of people who face sores, ulcers and even amputations due to severe peripheral artery disease.
A protein that binds to bile in the small intestine may hold the key to preventing infection and intestinal breakdown in people with conditions such as obstructive jaundice or irritable bowel syndrome, researchers at UT Southwestern Medical Center have discovered.
Researchers at Melbourne's Howard Florey Institute have discovered how the brain prioritises pain and thirst in order to survive - a mechanism that helps elite athletes to 'push through the pain barrier'.
For the first time, researchers can now peer inside intact cells to not only identify RNA-binding proteins, but also observe-in real-time-the intricate activities of these special molecules that make them key players in managing some of the cell's most basic functions.
According to researchers in the U.S., a virus may be why some people are obese.

Researchers at Johns Hopkins restored the normal growth of specific nerve cells in the cerebellum of mouse models of Down syndrome (DS) that were stunted by this genetic condition. The cerebellum is the rear, lower part of the brain that controls signals from the muscles to coordinate balance and motor learning.
A breakthrough by scientists at the University of Leicester in understanding mechanisms within the brain which cause injury could lead to better treatments in the future for conditions such as as cerebral palsy and multiple sclerosis.
It's just one little amino acid, but it makes all the difference in protecting the heart from the harmful effects of heart attack and cardiac failure. Researchers from the University of Michigan Medical School suggest this amino acid, called histidine, could be the key to a new therapy for cardiovascular disease
The absence of a key protein may lead to infertility. Researchers at the University of Illinois at Urbana-Champaign report that experiments involving mice -- to be detailed in the Proceedings of the National Academy of Sciences -- indicate that the transcription factor protein C/EBPb must be present in the uterus for pregnancy to occur.
In healthy volunteers, the equivalent of two cups of coffee reduced the body's ability to boost blood flow to the heart muscle in response to exercise, and the effect was stronger when the participants were in a chamber simulating high altitude, according to a new study in the Jan. 17, 2006, issue of the Journal of the American College of Cardiology.
Oregon Health & Science University Cancer Institute researchers have identified a protein fragment in some human breast cancers that may help predict a patient's chances of survival.
Low levels of nitric oxide gas can prevent and kill disease-causing bacteria by tricking them into thinking their time is up, according to scientists from the Environmental Biotechnology Cooperative Research Centre (EBCRC) and the University of New South Wales.
Obese and overweight individuals suffering metabolic syndrome and Type 2 diabetes showed significant health improvements after only three weeks of diet and moderate exercise even though the participants remained overweight.
Feeding tomato juice to mice kept them from developing emphysema after cigarette smoke exposure that was long enough to induce emphysema in a control group, Japanese researchers report in February issue of the American Journal of Physiology-Lung Cellular and Molecular Physiology.
A serendipitous comparison prompted by an old scientific image and involving an ancient but understudied molecule may lead to a new treatment strategy for injuries or illnesses in which blood clotting is paramount to survival.
Paul Greengard, Ph.D.,a Nobel Laureate researcher says that mice deficient in a protein, called p11, display depression-like behaviours, while those with sufficient amounts behave as if they have been treated with antidepressants.
As millions of Americans prepare their New Year’s resolutions to lose weight, eat better or exercise more, the University of Michigan Medical School is launching a new center that may help explain why so many resolutions fail, while others succeed.
According to a study to be published in the American Journal of Physiology-Heart and Circulation Physiology, a typical course of hyperbaric oxygen treatments increases by eight-fold the number of stem cells circulating in a patient's body.
