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.
In a rigorous new review of the antiarrhythmic drug dronedarone (Multaq), researchers at the Cedars-Sinai Heart Institute conclude that the controversial drug is only modestly effective and has no clear safety benefits.
A team of Swedish and American scientists has shown for the first time that carbon nanotubes can be broken down by an enzyme - myeloperoxidase (MPO) - found in white blood cells.
A drug whose clinical benefit in treating multiple sclerosis was discovered at Rush University Medical Center was approved by the Food and Drug Administration on January 22 and is now available in the U.S.
Chevy Chase, MD-Patients with type 2 diabetes are generally treated similarly despite the fact that they may have underlying differences that could affect their therapeutic response. Seeking to address this critical health issue, an international multidisciplinary group of experts just issued recommendations for individualized treatment in a consensus statement to be published in the April 2010 issue of the Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).
Rosetta Genomics, Ltd., a leading developer and provider of microRNA-based molecular diagnostics, announced today that starting April 1, 2010 physicians are able to send FNA cell block samples to Rosetta Genomics' CLIA-certified and CAP-accredited laboratory in Philadelphia for analysis using Rosetta's miRview squamous test. FNA is a less invasive method to obtain tumor cells compared with tumor resections or biopsies.
Researchers have gone some way to explaining what happens during premature births and how brain injury develops in premature babies. New findings show that inflammation in both the amniotic fluid and the baby's brain has a role to play, reveals a thesis from the Sahlgrenska Academy.
Every year, some 7.5 million mothers and new-borns die during pregnancy or childbirth, almost all of whom are in low and middle-income countries. One reason for this is the lack of trained medical staff, particularly doctors. A doctoral thesis from Karolinska Institutet now shows that a solution could be the training of nurses in caesarean sections and other life-saving surgery.
American Career College President Al Nederhood today announced that it will offer an Associate of Occupational Science Degree in Health Information Technology at its Anaheim campus beginning May 2010.
What do obesity, heart disease, depression, diabetes, and fibromyalgia have in common? The answer is vitamin D deficiency. More than 200 million Americans lack this essential vitamin and as a result suffer from a host of daily annoyances, chronic conditions, and even life-threatening illnesses.
When David Beckham limped off the pitch, thereby ending his chances of appearing at the Football World Cup this summer, sports injuries and rehabilitation techniques were once again front and back page news stories.
In what may provide the most compelling evidence to date, researchers at Columbia University Medical Center have illuminated how a genetic variant may lead to schizophrenia by causing a disruption in communication between the hippocampus and prefrontal cortex regions of the brain, areas believed to be responsible for carrying out working memory.
If research results continue to be repeated and are turned into clinical trials, a drug already approved for some uses could be marshaled - sooner than we expect - to prevent Alzheimer's disease in humans and improve health to the end of life.
Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, announced today that the Japanese Patent Office has granted claims in a second patent application (JP Application Number 2006-317758) for the Tuschl II patent series, entitled "RNA Interference Mediating Small RNA Molecules." In May 2008, the Japanese Patent Office granted a related set of claims in the Tuschl II patent series (JP 4 095 895).
Pfizer Canada is pleased to announce the recipients of its third Neuropathic Pain Research Awards Competition, which aims to fund and support Canadian innovation within independent neuropathic pain research in the areas of basic biomedical, clinical and health sciences.
Rosetta Genomics, Ltd., a leading developer and provider of microRNA-based molecular diagnostics, announces publication of an article describing the development and validation process of miRview™ mets, the company's microRNA-based test for identification of primary origin of metastases.
Researchers at the University of Alabama at Birmingham have found the first bio-marker for multiple sclerosis that might predict which patients will respond to a standard therapy and which will not.
Biologists have long known that an enzyme called the PI 3-kinase is a crucial actor in the main molecular pathway for insulin signaling in cells. Researchers at Joslin Diabetes Center now have uncovered startling evidence that one of the proteins in this enzyme also drives a pathway with an opposite result-triggering a stress response that leads to insulin resistance.
UCSF scientists report that they were able to prompt a new period of "plasticity," or capacity for change, in the neural circuitry of the visual cortex of juvenile mice. The approach, they say, might some day be used to create new periods of plasticity in the human brain that would allow for the repair of neural circuits following injury or disease.
Using a novel animal model to study craniofacial pain, researchers at Oregon Health & Science University's School of Dentistry have discovered that when tissues are inflamed, the nerve cells carrying pain information from the head to the brain produce in large quantities a protein involved in pain signaling.
UCSF scientists have used a novel cell-based strategy to treat motor symptoms in rats with a disease designed to mimic Parkinson's disease.
