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 study "Oxidative Stress is an Important Component of Airway Inflammation in Mice Exposed to Cigarette Smoke or Lipopolysaccharide" investigates the inflammatory responses in oxidative stress-deficient mice exposed to cigarette smoke.
The estimated 19 million Americans living with chronic kidney disease (CKD) face a high risk of death from cardiovascular disease. Recent studies have shown that a main source of this cardiovascular risk is CKD patients' high levels of blood phosphate.
When City traders have high morning testosterone levels they make more than average profits for the rest of that day, researchers at the University of Cambridge have discovered.
Even after the age of 70, people prone to feelings of anxiety, worry, distress and insecurity face a risk for a first lifetime episode of clinically significant depression, according to a unique study led by a University of Rochester Medical Center researcher.
Researchers at the University of Pennsylvania School of Medicine have discovered that a protein called leiomodin (Lmod) promotes the assembly of an important heart muscle protein called actin.
Cornell researchers have identified a mating mechanism that possibly could be adapted to prevent female mosquitoes from spreading the viruses that cause dengue fever, second only to malaria as the most virulent mosquito-borne disease in the tropical world.
The ability of brain cells to take in substances from their surface is essential to the production of a key ingredient in Alzheimer's brain plaques, neuroscientists at Washington University School of Medicine in St. Louis have learned.
Scientists at the Toronto General Hospital Research Institute have discovered a novel signaling pathway between three organs - the gut, the brain, and the liver - which lowers blood sugar when activated.
Researchers from the University of Pittsburgh and the University of Chicago were able to control heart muscle function in a new way after discovering the previously unknown role of two enzymes in heart muscle contraction, as detailed in the April 11 cover story of the Journal of Biological Chemistry.
Researchers have discovered a gene in flies whose activity rises and falls depending upon the amount of protein and sugar in the insects' diets.
Researchers from the University of Pennsylvania School of Medicine and colleagues at Merck Serono Research in Germany have found that two drugs bind to receptor sites on some tumors in different places at the same time, suggesting the possibility of a new combination therapy for certain types of cancer.
Endometriosis is a poorly understood condition that incapacitates and affects the productivity and lifestyle of millions of women around the world.
A recent University of Iowa study reveals a biological link between pain and fatigue and may help explain why more women than men are diagnosed with chronic pain and fatigue conditions like fibromyalgia and chronic fatigue syndrome.
Disruption of an individual's natural sleep-wake cycle has been determined to be a contributing factor in the development of organ disease.
In 2006 researchers investigating the interaction between the brain, behavior, and the immune system found that simply anticipating a mirthful laughter experience boosted health-protecting hormones.
Green tea is high in the antioxidant EGCG (epigallocatechin-3- gallate) which helps prevent the body's cells from becoming damaged and prematurely aged.
New research in monkeys suggests the feasibility of treating cocaine addiction with a "replacement" drug that mimics the effects of cocaine but has less potential for abuse - similar to the way nicotine and heroin addictions are treated.
