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.
Increasingly sophisticated imaging tools and techniques are emerging that make it possible to probe the organization and activity of the brain at the cellular and molecular level, leading to a better understanding of the complex networks that link brain structure and function.
Dieticians will tell you it isn't healthy to eat late at night: it's a recipe for weight gain. In fruit flies, at least, there's another consequence: reduced fertility.
NanoLogix, a biotechnology innovator in the rapid detection and identification of live-cell bacteria and microorganisms, announced today its BioNanoFilter (BNF) technology will undergo a clinical trial, led by Dr. Gian Carlo Di Renzo of the University of Perugia in Italy.
An Indiana University study that exposed older veterans with stroke to yoga produced "exciting" results as researchers explore whether this popular mind-body practice can help stroke victims cope with their increased risk for painful and even deadly falls.
Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, announced today the results from its Phase I clinical trial with ALN-VSP, a systemically delivered RNAi therapeutic for the treatment of advanced solid tumors with liver involvement.
Using a high-resolution single-molecule study technique, University of Illinois researchers have seen the very subtle differences between two branches of an important family of neurotransmitter-gated ion channels.
A space flight by millions of microscopic worms could help us overcome the numerous threats posed to human health by space travel. The Caenorhabditis elegans (C. elegans) have also given experts an insight into how to block muscle degradation in the sick and elderly.
Overweight and obese people looking to drop some pounds and considering one of the popular low-carbohydrate diets, along with moderate exercise, need not worry that the higher proportion of fat in such a program compared to a low-fat, high-carb diet may harm their arteries, suggests a pair of new studies by heart and vascular researchers at Johns Hopkins.
When April Gooding was born 19 years ago in Torrance, infants like her were called "test tube babies" and in vitro fertilization was still considered experimental. Nearly two decades later, almost 4 million IVF babies have been born, including several hundred who will join April and the fertility expert who helped create her as one of his first successes.
A cell phone-sized, wireless near-infrared device is as reliable as the current "gold standard" invasive tests in determining bladder disease, according to a study by researchers at the University of British Columbia, Vancouver Coastal Health and the Child & Family Research Institute (CFRI).
Retina Implant AG today announced that the Company's founder Professor Eberhart Zrenner M.D. was awarded the second prize by The European Society for Retina Specialists.
University of Calgary Faculty of Kinesiology researcher Elias Tomaras says the idea came to him while watching track and field sprinters warm-up for a race. "If you watch sprinters, short distance speed skaters or cyclists before their race, they will often warm-up for one to two hours, including several brief bouts of high intensity exercise. From an exercise physiology point of view, it seemed like it might be pretty tiring."
Currently, about 30 per cent of patients who receive oral surgery have their cancer recur. But a new, Canada-wide surgical trial using a new approach to remove tumours and pre-cancerous cells from the mouths of those diagnosed with early-stage oral cancer offers new hope for patients.
For many years doctors believed the estrogen women consumed in the form of oral contraceptives and hormone replacement therapy pills was good for their patients' hearts. Recent studies however have shown that long-term exposure to estrogen can be a danger to women as it has been associated with high blood pressure, a key link to heart- and brain-attacks.
In a ceremony today, the University of Pennsylvania announced a collaboration agreement with the Chinese Academy of Sciences to develop a joint Center of Excellence in Brain Mapping for the purpose of collaborative research and education in neuroimaging.
A high-fat diet during pregnancy may program a woman's baby for future diabetes, even if she herself is not obese or diabetic, says a new University of Illinois study published in the Journal of Physiology.
Brenda Milner, Ph.D., a pioneer in the field of cognitive neuroscience whose discoveries revolutionized the understanding of memory, will be awarded the 2011 Pearl Meister Greengard Prize from The Rockefeller University.
Recalling painful memories while under the influence of the drug metyrapone reduces the brain's ability to re-record the negative emotions associated with them, according to University of Montreal researchers at the Centre for Studies on Human Stress of Louis-H. Lafontaine Hospital.
In space, the old movie slogan declares, "no one can hear you scream." On the other hand, you might look like it, with puffy face, swollen eyes and distended neck veins. This is what happens when, screaming or not, bodily fluids shift in the absence of gravity.
Archimedes Inc., a healthcare modeling company, today announced the launch of a new web interface, ARCHeS Innovator, which will give health experts direct access to many of the features of the Archimedes Model.
