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.
Australians researchers have put out a call for 400 people to take part in a study on depression.
International research collaborators have identified a new family of proteins, TPC2 (two-pore channels), that facilitates calcium signaling from specialized subcellular organelles.
When Francois Abboud began his work at the University of Iowa in 1960, little was known about the constant physiological chatter between the brain and the blood vessels.
Healthcare Reform should start with "evidence-based reimbursement", structuring physician payment incentives around existing empirical evidence of clinical benefit, which would improve quality and reduce the cost of healthcare, says a commentary written by two cardiologists and published in Circulation: Cardiovascular Quality and Outcomes .
Exercise has many benefits for adults, teens, and youngsters. It is less clear what benefit, if any, exercise may have during fetal growth during gestation.
For the past decade, researchers have tried to tweak cells at the gene and nucleus level to reprogram their identity.
NextBio has announced the receipt of a Small Business Innovation Research (SBIR) grant from the U.S. National Institutes of Health (NIH).
Poor aerobic fitness is strongly associated with obesity and its consequent risks of heart disease, strokes and diabetes - now considered worldwide epidemics.
Runners clutching bottles of energy drink are a common sight, and it has long been known that sugary drinks and sweets can significantly improve athletes' performance in endurance events.
Artificial heart pacemakers have saved and extended the lives of thousands of people, but they have their shortcomings - such as a fixed pulse rate and a limited life.
University of Nevada School of Medicine scientists in the Department of Physiology and Cell Biology have discovered insight into the reproductive workings of the male sex chromosome that may have significant implications for male infertility and contraception.
Researchers at the Joslin Diabetes Center have demonstrated that adult humans still have a type of "good" fat previously believed to be present only in babies and children.
Researchers at the Joslin Diabetes Center have shown for the first time that insulin plays a key role in suppressing levels of glucagon, a hormone involved in carbohydrate metabolism and regulating blood glucose levels.
Research led by David Hess of the Robarts Research Institute at The University of Western Ontario has identified how to use selected stem cells from bone marrow to grow new blood vessels to treat diseases such as peripheral artery disease.
A collaboration of University of Pennsylvania and University of Wisconsin chemists and anesthesiologists have identified a fluorescent anesthetic compound that will assist researchers in obtaining more precise information about how anesthetics work in the body and will provide a means to more rapidly test new anesthetic compounds in the search for safer and more effective drugs.
Nicotine isn't just addictive. It may also interfere with dozens of cellular interactions in the body, new Brown University research suggests.
In a study comparing the ability of various medical techniques to accurately determine the extent of heart disease and stratify patients according to disease severity, researchers found that myocardial perfusion testing with gated single photon emission computed tomography (gated SPECT) was a more accurate predictor of prognosis in chronic ischemic heart disease (IHD)-a painful condition caused by a temporary reduction of oxygen-rich blood to the heart.
Octogenarian women were unable to increase muscle mass after a 3-month weight lifting program targeted at strengthening the thigh muscle, according to a new study from the Journal of Applied Physiology.
Understanding the tens of thousands of proteins that compose the human proteome has emerged as a key challenge of this century, and research efforts to date have already enabled major advances in drug discovery and understanding basic biology.
Patients with moderate to severe chronic obstructive pulmonary disease (COPD) exhibit a disordered breathing-swallowing pattern that may account for their higher risk of aspiration pneumonia, according to new research from the University of Pittsburgh.
