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.
Leaders in biomedical education at Johns Hopkins University School of Medicine are calling for a radical new approach to post-graduate training in the life sciences to address significant challenges, including an avalanche of new discoveries in the last decade and the need to transcend traditional departmental boundaries to understand biological processes at multiple levels.
It's common enough for researchers to look at the impacts of prescribed drugs on the body. And if you're a diabetes researcher who believes that exercise has great benefits for those with type 2 diabetes, you're hoping your research will show that. But when Normand Boul- looked at the dual impacts of exercise and metformin - two of the most commonly-prescribed modalities for glucose control - on that very outcome, the hoped-for double whammy wasn't the result.
Heart disease has sometimes been considered a men's health issue, but the statistics prove otherwise. In the US alone, more than 42 million women live with the problem. Heart disease is responsible for more than one-third of deaths among American women each year, making it the number one killer of females older than 20.
By employing optogenetics, a new field that uses genetically altered cells to respond to light, and a tandem unit cell (TCU) strategy, researchers at Stony Brook University have demonstrated a way to control cell excitation and contraction in cardiac muscle cells, the details of which are published in the early online edition of Circulation: Arrhythmia & Electrophysiology: "Stimulating Cardiac Muscle by Light: Cardiac Optogenetics by Cell Delivery."
Much like cities organize contingency plans and supplies for emergencies, chronic infectious diseases like HIV form reservoirs that ensure their survival in adverse conditions. But these reservoirs-small populations of viruses or bacteria of a specific type that persist despite attack by the immune system or drug treatment-are not always well understood.
University of Adelaide research has shown for the first time that obesity directly causes electrical abnormalities of the heart.
University of Iowa scientists have discovered a new role for a protein that is mutated in Usher syndrome, one of the most common forms of deaf-blindness in humans. The findings, which were published Aug. 8 in Nature Neuroscience, may help explain why this mutation causes the most severe form of the condition.
Researchers at the University of Edinburgh claim that it is possible to learn about a person’s childhood by looking at the symmetry of their face.
In 1991, Carl Lewis was both the fastest man on earth and a profound long jumper, perhaps the greatest track-and-field star of all time in the prime of his career. On June 14th of that year, however, Carl Lewis was human. Leroy Burrell blazed through the 100-meters, besting him by a razor-thin margin of three-hundredths of a second. In the time it takes the shutter to capture a single frame of video, Lewis's three-year-old world record was gone.
A major Center that will propel scientific efforts to pinpoint the specific genes involved in causing immune diseases, cancer and other diseases will be opened today at the La Jolla Institute for Allergy & Immunology.
The Medical College of Wisconsin has received a five-year, $13 million grant to establish a National Center for Systems Biology.
A study published in the British medical journal `The Lancet' on Thursday revealed that the risk of developing coronary heart disease is 25% higher for women smokers compared with men.
Researchers at Joslin Diabetes Center and Children's Hospital Boston have shown that a type of "good" fat known as brown fat occurs in varying amounts in children - increasing until puberty and then declining -- and is most active in leaner children.
Valkee, inventor of the world's first bright-light headset, and scientists from the University of Oulu will present new findings on human brain's photosensitivity at the Scandinavian Physiology Society Annual Meeting 2011, August 12-14.
A Baylor University study has found that a popular nutritional supplement that is marketed to lead to greater muscle strength through increasing blood flow to the muscle does not increase blood flow as claimed on the bottle.
Biologists and psychologists know that light affects mood, but a new University of Virginia study indicates that light may also play a role in modulating fear and anxiety.
Springer has signed a book partnership agreement with the American Physiological Society (APS) to publish titles in three APS book series as well as individual monographs and contributed volumes. The new publications are aimed primarily at researchers and will support Springer’s growing physiology publishing program.
Stem cell researchers at UCLA have uncovered for the first time why adult human cardiac myocytes have lost their ability to proliferate, perhaps explaining why the human heart has little regenerative capacity.
Our bodies are perfectly capable of renewing billions of cells every day but fail miserably when it comes to replacing damaged organs such as kidneys. Using the flatworm Schmidtea mediterranea-famous for its capacity to regrow complete animals from minuscule flecks of tissue-as an eloquent example, researchers at the Stowers Institute for Medical Research demonstrated how our distant evolutionary cousins regenerate their excretory systems from scratch.
Elsevier / MC Strategies, a pioneer in providing eLearning solutions to more than 1,300 healthcare organizations, today announced the addition of a white paper, "Two Years and Counting", as well as updates to its eBook, A Guide to Education and Training for ICD-10 Implementation, to its ICD-10 Roadmap.
