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.
Zen meditation - a centuries-old practice that can provide mental, physical and emotional balance - may reduce pain according to Université de Montréal researchers.
A team of Vanderbilt University Medical Center investigators has developed a group of chemical compounds that could represent a new class of drugs for treating cancer.
A Northwestern University-led research team reports that insulin, by shielding memory-forming synapses from harm, may slow or prevent the damage and memory loss caused by toxic proteins in Alzheimer's disease.
Women are not from Venus any more than men are from Mars. But even though both sexes are perfectly terrestrial beings, they are not lacking in other differences. And not only in their reproductive organs and behavior, either, but in such unsexy characteristics as the propensity for drug abuse, fine motor control, reaction to stress, moods and many brain structures.
Mice whose fat cells were allowed to grow larger than fat cells in normal mice developed "healthy" obesity when fed a high-fat diet, researchers at UT Southwestern Medical Center found in a new study.
Helicobacter pylori , a Gram-negative, flagellated, microaerophilic bacterium, can selectively colonize in the human stomach.
Individual nerve cells in the front part of the brain can hold traces of memories on their own for as long as a minute and possibly longer, researchers at UT Southwestern Medical Center have found.
Researchers at UT Southwestern Medical Center have identified in mice a compound that liberates cholesterol that has inappropriately accumulated to excessive levels inside cells.
The University of Sydney is embarking on one of its largest ever recruitment drives in the wake of recent federal funding for an international centre of expertise in obesity, diabetes and cardiovascular disease.
If you have trouble keeping weight off and you're wondering why - the surprising answer may well be the cheeseburgers you ate - when you were a toddler.

Ten years ago, the Chinese National Human Genome Center at Shanghai (South Center, hereafter) was established in the Zhangjiang HiTech Park of Pudong District in Shanghai.
Obstructive sleep apnea decreases blood flow to the brain, elevates blood pressure within the brain and eventually harms the brain's ability to modulate these changes and prevent damage to itself, according to a new study published by The American Physiological Society.
