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 the University of Iowa have worked out the exact function of an enzyme that is critical for normal muscle structure and is involved in several muscular dystrophies. The findings, which were published Jan. 6 in the journal Science,, could be used to develop rapid, large-scale testing of potential muscular dystrophy therapies.
We've all seen the story in the news before. Whether it's the death of a physically fit high school athlete at football training camp in August, or of an elderly woman gardening in the middle of the day in July, heat stroke is a serious, life-threatening condition for which there is no treatment beyond submersion in ice water or the application of ice packs to cool the body to a normal temperature.
Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, announced today that it has filed a Clinical Trial Application (CTA) with the U.K. Medicines and Healthcare products Regulatory Agency (MHRA) to initiate a Phase I clinical trial with ALN-TTR02, an RNAi therapeutic targeting transthyretin (TTR) for the treatment of TTR-mediated amyloidosis.
Other than Olympic race walkers, people generally find it more comfortable to run than walk when they start moving at around 2 meters per second - about 4.5 miles per hour.
The American Association of Anatomists' 2012 Basmajian Award will be presented on April 24 to Todd Hoagland, associate professor in the department of cell biology, neurobiology and anatomy at the Medical College of Wisconsin.
Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, announced today the achievement of positive preliminary results from its ongoing clinical trial of ALN-PCS, an RNAi therapeutic targeting PCSK9 for the treatment of severe hypercholesterolemia.
A new study led by the University of Colorado Boulder could be a wake-up call for parents of toddlers: Daytime naps for your kids may be more important than you think.
Immune system abnormalities that mimic those seen with autism spectrum disorders have been linked to the amyloid precursor protein (APP), reports a research team from the University of South Florida's Department of Psychiatry and the Silver Child Development Center.
Some individuals with severe aortic stenosis - also known as narrowing of the aortic valve in the heart - who are not well enough to undergo open heart surgery have a new treatment option thanks to a new procedure now available in Kentucky from University of Louisville physicians at Jewish Hospital.
Research led by Shyamal Desai, PhD, Assistant Professor of Biochemistry and Molecular Biology at LSU Health Sciences Center New Orleans, has discovered a key change in the body's defense system that increases the potential for breast cancer to spread to other parts of the body.
Lung cancer takes a heavy toll, contributing to more cancer deaths in the United States each year than breast, prostate and colon cancers combined. Contributing to this poor prognosis is the fact that lung cancer often goes undetected until the disease has reached an advanced and more difficult-to-treat stage.
The American Society for Biochemistry and Molecular Biology has named Elisabetta Ullu, professor of internal medicine and cell biology at the Yale University School of Medicine, the winner of the society's inaugural Alice and C.C. Wang award.
Half the drugs used today target a single class of proteins - and now scientists have identified an important molecular player critical to the proper workings of those proteins critical to our health.
