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.
Researchers at Oregon Health & Science University have discovered that an antioxidant designed more than a dozen years ago to fight damage within human cells significantly helps symptoms in mice that have a multiple sclerosis-like disease.
Working in mice, researchers at Washington University School of Medicine in St. Louis report developing a gene delivery method long sought in the field of gene therapy: a deactivated virus carrying a gene of interest that can be injected into the bloodstream and make its way to the right cells.
New research shows mortality rates are two times higher in postmenopausal women with rheumatoid arthritis (RA) and anti-cyclic citrullinated peptide (anti-CCP) antibodies. Findings published in the American College of Rheumatology (ACR) journal Arthritis & Rheumatism, soon to be called Arthritis & Rheumatology, indicate the higher mortality rates persisted after adjusting for age, positive rheumatoid factor, positive antinuclear antibodies (ANA) and disease modifying anti-rheumatic drug (DMARD) use.
Scientists at The Scripps Research Institute (TSRI) have demonstrated a drug-discovery strategy with a double payoff-it enables the rapid selection of chemical compounds that have a desired effect on cells and also highlights how the compounds work.
Researchers at University of Michigan have illuminated an aspect of how the metabolic system breaks down in obesity. The findings provide additional evidence that a drug entering clinical trials at the university could reverse obesity, Type 2 diabetes and fatty liver disease in humans.
New imaging research from Western University (London, Canada) has demonstrated that a magnetic resonance imaging approach called quantitative susceptibility mapping can be an important tool for diagnosing and tracking the progression of Multiple Sclerosis and other neurological diseases.
A collaborative pharmaceutical project focused on improving the pathway for developing paediatric formulations has been given the go-ahead after successfully securing an innovation grant.
Even if you consume significantly more calories than you burn off this Christmas, a short, daily bout of exercise will stave off most of the negative effects of over-eating and inactivity, according to scientists at the University of Bath.
High blood pressure affects approximately one in three adults in the Americas, Europe, some Asian countries and Australia, and one billion people worldwide.
High blood pressure affects approximately one in three adults in the Americas, Europe, some Asian countries and Australia, and one billion people worldwide. Because of this epidemic, The American Society of Hypertension, Inc. and the International Society of Hypertension are pleased to announce the creation of first-of-their-kind guidelines for the diagnosis and treatment of Hypertension: "Clinical Practice Guidelines for the Management of Hypertension in the Community."
Researchers from Echelon Biosciences, Inc. and collaborators from the University of Utah report the use of ATX-Red AR-2 as a new imaging agent that effectively illuminates tumors.
The bedtime you select for your toddler may be out of sync with his or her internal body clock, which can contribute to difficulties for youngsters attempting to settle in for the night, according to a new University of Colorado Boulder study.
Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, announced today that it has initiated a pilot Phase II study with ALN-TTRsc, a subcutaneously delivered RNAi therapeutic targeting the transthyretin gene in development for the treatment of TTR-mediated amyloidosis.
For tens of millions of Americans, there's no such thing as the sound of silence. Instead, even in a quiet room, they hear a constant ringing, buzzing, hissing, humming or other noise in their ears that isn't real. Called tinnitus, it can be debilitating and life-altering.
Wake Forest Baptist Medical Center researchers are gaining a better understanding of the neurochemical basis of addiction with a new technology called optogenetics.
Daily exercise lessens many of the harmful physiological effects of short-term overeating and inactivity, shows a new study [published 15 December] in The Journal of Physiology, which is well timed with the Christmas holiday approaching.
Widely used treatments for type 2 diabetes have different effects on the hearts of men and women, even as the drugs control blood sugar equally well in both sexes, according to researchers at Washington University School of Medicine in St. Louis.
Researchers have found evidence that the gastrointestinal tract plays a role in the inflammatory pathology of bipolar disorder, suggesting the need to consider dietary modification and anti-inflammatory treatment for some patients.
Sleep, or the lack of it, seems to affect just about every aspect of human physiology. Yet, the molecular pathways through which sleep deprivation wreaks its detrimental effects on the body remain poorly understood.
Federal legislation encouraging the study of drugs in pediatric patients has resulted in very few labeling changes that include new infant information, according to a study by Matthew M. Laughon, M.D., M.P.H., of the University of North Carolina at Chapel Hill, and colleagues.
