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.
Using a novel three-part screening process, scientists at Dana-Farber Cancer Institute have identified a gene that is made inappropriately in about a third of all breast cancers.
Researchers at the University of Pennsylvania have found a link between some of the world's most common parasites that cause infection and disease throughout the developing world and their attraction to a chemical secreted from human and animal skin.
Fluorescence diffuse optical tomography, or FDOT, relies on the presence of fluorophore molecules in tissue that re-radiate fluorescent light after illumination by excitation light of a different color.
Northwestern University researchers have discovered a drug that slows and may even halt the progression of Parkinson's disease.
Scientists in the U.S. say they have discovered a drug that slows and might even stop the progression of Parkinson's disease.
Over the past several years, animal studies have shown that high-fat, low-carbohydrate “ketogenic” diets cause demonstrable changes in metabolism and subsequent weight loss.
A newly discovered interplay of cells in one of the brain's memory centers sheds light on how you recall your grocery list, where you laid your keys, and a host of important but fleeting daily tasks.
Most women who are obese can safely exercise and diet to lose weight during pregnancy, according to a small pilot study conducted by Saint Louis University researchers.
The synthetic form of a hormone previously found to produce a feeling of fullness when eating and reduce body weight, also may help curb binge eating and the desire to eat high-fat foods and sweets.
In today's fast-moving world of look-alike hotel rooms and comparable corridors, it can take a bit of thinking to answer this simple question.
Why do so many people continue to suffer from life-altering, chronic pain long after their injuries have actually healed"
A natural substance secreted by fat cells can protect blood vessels from the damaging effects of inflammation, one of the factors that contribute to heart disease.

In a paper published in The Journal of Physiology, Frank de Paoli and colleagues, working at the University of Aarhus in Denmark, add to the growing literature leading to a more complete understanding of the physiological role of lactic acid production in muscle.
Forthcoming in Physiological and Biochemical Zoology, a fascinating new selection of papers collects leading experimental research in evolution and artificial selection, providing insight into how organisms adapt to changing environmental conditions and fluctuations.
Communication ability among children who are intellectually disabled or have communication limitations (such as autism, down syndrome, or cerebral palsy) may soon be improved thanks to a research group of the University of Granada.
Scientists at the University of Virginia and the Medical College of Wisconsin have discovered that a gene that participates in the regulation of the body's biological rhythms may also be a major control in regulating metabolism.
Lack of blood flow to the intestines during surgery, to the heart during a heart attack or to the brain during a stroke can cause damage to the organ involved.
Researchers from the Uniformed Services University of the Health Sciences (USU) are pursuing efforts to find new ways to prevent and to treat the increasing numbers of combat troops who are suffering from injuries due to traumatic brain injury (TBI).
