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.
Frustrated by the slow pace of new drug development for a condition that causes pediatric brain tumors, a neurologist at Washington University School of Medicine in St. Louis decided to try to fine-tune the animal models used to test new drugs.
Low-fat diets are more effective in preserving and promoting a healthy cardiovascular system than low-carbohydrate, Atkins'-like diets, according to a new study by researchers at the Medical College of Wisconsin in Milwaukee.
The cancer-related protein Akt may profoundly influence the fate of the tau protein, which forms bundles of tangled nerve cell fibers in the brain associated with Alzheimer's disease, reports a new study led by researchers at the University of South Florida and the Mayo Clinic in Jacksonville, FL.
Hormones produced by the heart eliminated human pancreatic cancer in more than three-quarters of the mice treated with the hormones and eliminated human breast cancer in two-thirds of the mice, according to researcher David Vesely, a doctor at the James A. Haley Veterans Hospital in Tampa and a professor at the University of South Florida (USF).
Australian scientists say a hormone that suppresses hunger may be far more powerful when it comes to weight loss than first thought.
Pregnant women who suffer from the high risk condition pre-eclampsia which leads to the death of hundreds of babies every year are putting the lives of their unborn children at significantly increased risk if they continue to smoke during pregnancy.
Eating curcumin, a natural ingredient in the spice turmeric, may dramatically reduce the chance of developing heart failure, researchers at the Peter Munk Cardiac Centre of the Toronto General Hospital have discovered.
Researchers from Boston University School of Medicine (BUSM) have found that previtamin D3 production varies depending on several factors including skin type and weather conditions.
It's no secret that obesity is a problem in humans. Reality television makes millions of dollars chronicling the efforts of Americans attempting to shed excess weight.
Patients with leukemia, certain autoimmune diseases and genetic defects such as sickle-cell anemia can be treated with blood stem cells either from a donor's bone marrow or from cord blood - but the supply of effective stem cells often runs short.
A new University of Illinois study shows that exercise-trained mice get far fewer gallstones than sedentary mice and identifies potential mechanisms to explain why this occurs.
"That was good!" "Do it again."This is what the brain says when people use tobacco, as well as 'hard drugs' such as heroin.
Researchers at the University of Pennsylvania School of Medicine have demonstrated that a bacterial toxin from the common bacterium Staphylococcus aureus shuts down the control mechanism of the tunnel, called an ion channel, in immune cell membranes.
One drink of either red wine or alcohol slightly benefits the heart and blood vessels, but the positive effects on specific biological markers disappear with two drinks, say researchers at the Peter Munk Cardiac Centre of the Toronto General Hospital.
"That was good!" "Do it again." This is what the brain says when people use tobacco, as well as ‘hard drugs' such as heroin.
Expertise from across the University of Leeds is to be channelled into a new research centre that aims to progress the understanding, treatment and prevention of cardiovascular diseases.
The new study shows that the fatigue that marathoners and other extreme athletes feel at the end of a race is caused by a tiny leak inside their muscles that probably also saps the energy from patients with heart failure.
Researchers from the Boston University School of Medicine (BUSM) have demonstrated that in mice, the use of barbells may be as important to losing weight and improving health as the use of running shoes.
People with unrelenting pain don't only suffer from the non-stop sensation of throbbing pain.
An unexpected finding turned out to be a clue leading researchers at Washington University School of Medicine in St. Louis to propose a new treatment approach for Niemann-Pick disease, a rare, deadly neurodegenerative disorder.
