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.
Patients from ethnic minority and mixed-racial backgrounds are less likely to receive a lifesaving bone marrow transplant than Caucasian patients with the same disease due to lack of matching donors, according to the National Marrow Donor Program.
Researchers may have found a way to block kidney-destroying inflammation and help damaged kidney cells recover.
A new study published in the American College of Rheumatology (ACR) journal, Arthritis Care & Research, reveals that women with rheumatoid arthritis (RA) who were on methotrexate (MTX), a drug commonly used to reduce inflammation caused by RA, had lower rates of induced abortions compared to women with RA who were not exposed to the medication.
Researchers at the Linda Crnic Institute for Down Syndrome and the University of Colorado School of Medicine have found that a single mechanism may underlie the damaging effect of cholesterol on the brain and on blood vessels.
Specific DNA once dismissed as junk plays an important role in brain development and might be involved in several devastating neurological diseases, UC San Francisco scientists have found.
Like finally seeing all the gears of a watch and how they work together, researchers from UCLA and UC Berkeley have, for the first time ever, solved the puzzle of how the various components of an entire telomerase enzyme complex fit together and function in a three-dimensional structure.
Computational models of the human heart can be very useful in studying not just the basic mechanisms of heart function, but also to analyze the heart in a diseased state, and come up with methods for diagnosis and therapy.
The very serious hereditary disease HDLS was discovered in 1984 in Sweden. Many HDLS patients are still incorrectly diagnosed with Alzheimer's disease, MS or Parkinson's disease, but researchers at the Sahlgrenska Academy, University of Gothenburg, Sweden, have now developed a more certain diagnosis method - and are seeking to find a treatment for the "unknown" neurological disorder.
A novel study shows women who undergo surgical treatment for endometriosis have a lower risk of developing ovarian cancer. According to results published in Acta Obstetricia et Gynecologica Scandinavica, a journal of the Nordic Federation of Societies of Obstetrics and Gynecology, hormonal treatments for endometriosis did not lower ovarian cancer risk.
New research suggests that patients with knee osteoarthritis (OA) who wear flat, flexible footwear (mobility shoes) had significant reduction in knee loading-the force placed upon the joint during daily activities.
Setting a mouse free to roam might alarm most people, but not so for nuclear imaging researchers from the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility, Oak Ridge National Laboratory, Johns Hopkins Medical School and the University of Maryland who have developed a new imaging system for mouse brain studies.
Studies show 97 percent of American adults get less than 30 minutes of exercise a day, which is the minimum recommended amount based on federal guidelines. New research from the University of Missouri suggests certain genetic traits may predispose people to being more or less motivated to exercise and remain active.
The recent discovery of circulating "nano-sized extracellular vesicles" (EVs) carrying proteins and nucleic acids derived from brain tumors may lead to exciting new avenues for brain cancer diagnosis, monitoring, and treatment, according to a special article in the April issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.
Deborah E. Wiley, Chair of The Wiley Foundation, John Wiley & Sons, Inc. (NYSE: JWa & JWb) today awarded the 2013 Wiley Prize in Biomedical Sciences to Dr. Michael Young, Rockefeller University, Dr. Jeffrey Hall, Brandeis University (Emeritus), and Dr. Michael Rosbash, Brandeis University.
Johns Hopkins scientists have found out how a gout-linked genetic mutation contributes to the disease: by causing a breakdown in a cellular pump that clears an acidic waste product from the bloodstream.
A study from the University of North Carolina School of Medicine offers new insights into how the nervous system processes hot and cold temperatures. The research led by neuroscientist Mark J. Zylka, PhD, associate professor of cell biology and physiology, found an interaction between the neural circuits that detect hot and cold stimuli: cold perception is enhanced when nerve circuitry for heat is inactivated.
Research from Western University and Lawson Health Research Institute sheds new light on a gene called ATRX and its function in the brain and pituitary.
Researchers from the UK determined that developmental delays are present in children within six weeks following convulsive status epilepticus -a seizure lasting longer than thirty minutes.
Researchers at the University of Calgary's Hotchkiss Brain Institute have discovered that stress circuits in the brain undergo profound learning early in life. Using a number of cutting edge approaches, including optogenetics, Jaideep Bains, PhD, and colleagues have shown stress circuits are capable of self-tuning following a single stress.
Researchers of the Max Delbr-ck Center for Molecular Medicine and the Leibniz Institute of Molecular Pharmacology in Berlin-Buch, Germany, have now detected a substance that can prevent the accumulation of fluid in body tissue and thus edema formation.
