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.
Cyntellect a privately-held biotechnology company, has announced the issuance of U.S. Patent No. 6,753,161 covering the Company's LaserFect(TM) technology.
Scientists have produced a prion protein that can trigger the development of a neurological disorder in mice that is similar to "mad cow" disease, according to a new study supported by the National Institute on Aging, a part of the National Institutes of Health.
The DNA of rare and endangered species is to be preserved for future generations, thanks to a groundbreaking new project involving scientists at The University of Nottingham, the Institute of Zoology and London’s Natural History Museum.
Feeling sick can be "all in the head" for people with inflammatory disorders or for those receiving immunotherapy, say Robert Dantzer and Keith Kelley, professors in the department of animal sciences at the University of Illinois at Urbana-Champaign.
For most of us, hot weather leads to elevated internal and skin temperatures, which increase sweat rates and skin blood flow. How much we sweat can also depend on nonthermal factors such as exercise, baroreceptor loading status, and body fluid status.
Every morning, millions of adults consume voluminous cups of coffee, seeking the jolting effect of caffeine. As these adults consume their coffee, they do so unaware that some of the youngest Americans are also getting a treatment of caffeine - not to stay awake, but to assist in treating a major sleep disorder found in some neonates.
Russian scientists are currently creating a pleasant and harmless vaccine, and edible one at that. So far, they managed to incorporate the protein gene – HIV antigen in tomatoes. The research is supported by International Science and Technology Center.
A protein responsible for regulating acid levels within cells - and pumping out acid accumulated in cardiac cells after a heart attack - activates in direct response to changes in a cell's volume, according to a new study by researchers at UT Southwestern Medical Center at Dallas.
Researchers from the University of Iowa have have shown for the first time that gene therapy delivered to the brains of living mice can prevent the physical symptoms and neurological damage caused by an inherited neurodegenerative disease that is similar to Huntington's disease (HD).
Scientists at the University of North Carolina at Chapel Hill have discovered key steps involved in regulating nerve growth and regeneration that may have implications for spinal cord research.
The Children's Digestive Health and Nutrition Foundation (CDHNF) with the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) today announced the launch of a new educational campaign on celiac disease
New findings about a protein that keeps cells alive by opening and closing pores within a cell's membrane may open the door to the development of new antibiotics.
Concurrent with the national obesity epidemic has been a rise in the discoveries about how the body controls appetite and food intake.
After months of torturous dieting, there is nothing more frustrating than to find that the lost weight has returned.
Only recently was a type of diuretic known as thiazides been found to be superior to angiotensin-converting enzyme (ACE) inhibitors and calcium antagonists (calcium channel blockers) in preventing one or more major types of cardiovascular disease.
Genetically engineered mice, created at the University of Michigan Medical School, are living every dieter's dream.
A new £18M Medical Research Council (MRC) facility to understand and compare the genetics of disease in mice and humans will be opened today, Wednesday 30 June, by Lord Sainsbury, Minister for Science and Technology.
RMIT University researchers have pioneered a new generation of ‘pre-event’ cooling jackets to reduce the body temperature of elite athletes.
An investigation of how blood flows through stents after opening clogged arteries has led a team of researchers at the Medical College of Wisconsin Cardiovascular Center in Milwaukee to suggest that stents designed with thinner and fewer linkages may be the basis of a new generation of stents.
Babies exposed to excess hormones in the womb are not only at increased risk of developing heart disease and diabetes in later life but can pass these risks to their children.
