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.
Dr. John C. Longhurst, director of the Susan Samueli Centre for Integrative Medicine at UC Irvine ,and researchers, have found that acupuncture using low levels of electrical stimulation can lower elevations in blood pressure by as much as 50 percent.
Mice with glowing green hearts have yielded the latest clue in the search for molecules involved in structural heart disease. Vanderbilt University Medical Center investigators found that blocking the activity of a single protein, called CaM kinase, in the mouse heart protects against the damaging effects of a heart attack.
Children in Europe and other parts of the world are entering puberty at an ever younger age. The reasons for this are unknown, and the EU is now financing a major three-year project called PIONEER in a determined effort to get to the root of the problem. Two Swedish research groups are involved in the project, both from Karolinska Institutet.
As the most common cause of adult disability in the United States, stroke leaves many survivors unable to perform tasks that were once part of their daily routine. Much of the time the disabilities are treatable, but the high cost of rehabilitation therapy leaves many patients to cope on their own.
Scientists have identified an important link between kidney damage and cardiac problems, creating new possibilities for treating the primary cause of death in kidney disease patients.
Mice lacking a key protein involved in cholesterol regulation have low-density lipoprotein, or "bad" cholesterol, levels more than 50 percent lower than normal mice, and researchers suggest that inhibiting the same protein in humans could lead to new cholesterol-lowering drugs.
Why does extra fat around the waist increase the risk of heart disease? A new study by Wake Forest University Baptist Medical Center researchers and colleagues suggests that inflammation may be the key.
Researchers now have the physical evidence to show why it's important for older people to exercise. And it comes with the discovery that, in aging racehorses, regular aerobic workouts decreased the prevalence of muscle damage that can be caused by exertion.
Acupuncture treatments using low levels of electrical stimulation can lower elevations in blood pressure by as much as 50 percent, researchers at the Susan Samueli Center for Integrative Medicine at UC Irvine have found.
A Virginia Commonwealth University research group has been awarded $3.2 million in federal grants for two shock-related studies, one with battlefield implications and the other for emergency medicine.
Scientists at the University of Liverpool, supported by the British Heart Foundation, are studying blood flow in the brain to further medical understanding of cardiovascular disease.
Whitehead Institute has joined ten other leading biomedical organizations in an $18 million, three-year public-private consortium that will create a comprehensive library of gene inhibitors to be made available to the entire scientific community.
Doctors working at the edge of extreme are set to climb the world’s tallest mountain to look death in the face – and take its pulse. The medical research team will make the first ever measurements of blood oxygen in the ‘death zone’, at altitudes above 8,000 metres where the human body has struggled - and frequently failed - to survive.
New research at the University of California, Berkeley, raises such a possibility. It shows that healthy mice given only 5 percent fewer calories than mice allowed to eat freely experienced a significant reduction in cell proliferation in several tissues, considered an indicator for cancer risk.
An international team led by researchers at the Department of Human Evolution, Max Planck Institute for Evolutionary Anthropology in Liepzig, Germany and Washington University in St. Louis, has extracted and sequenced protein from a Neanderthal from Shanidar Cave, Iraq dating to approximately 75,000 years old.
A biologist at Washington University in St. Louis is giving the VIP treatment to laboratory mice in hopes of unraveling more clues about our biological clock.
NYU Medical Center's Department of Cardiothoracic Surgery will conduct a live surgical webcast on March 9th at 3 pm ET of a minimally invasive mitral valve repair procedure.
Scientists at the University of Maryland School of Medicine in Baltimore have identified a way to prevent Type I diabetes in rats that are genetically prone to develop the disease.
People are as different on the inside as they are on the outside, making it difficult to predict how an individual will respond to a surgical intervention without resorting to statistics and educated guesses.
Leaping tall buildings in a single bound may be out of the question, but the genetically engineered "supermice" in Ormond MacDougald's laboratory at the University of Michigan Medical School are definitely stronger than average.
