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.
A common genetic variation links to both bladder cancer risk and to the length of protective caps found on the ends of chromosomes, scientists at The University of Texas MD Anderson Cancer Center reported today at the AACR 102nd Annual Meeting.
A lack of vitamin D, even in generally healthy people, is linked with stiffer arteries and an inability of blood vessels to relax, research from the Emory/Georgia Tech Predictive Health Institute has found.
Eating fewer, regular-sized meals with higher amounts of lean protein can make one feel more full than eating smaller, more frequent meals, according to new research from Purdue University.
To parents, learning that a child has been diagnosed with autism can be overwhelming. Children with the disorder can seem trapped in a world of their own, without friends or even a conception of friendship. Many prefer to play alone. Some lose the ability to speak more than a few words.
New research published today in The Journal of Physiology sheds light on areas of the brain thought to be the root cause of Sudden Infant Death Syndrome - the poorly understood condition also known as 'cot death'.
Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, today announced that it has completed enrollment in its ALN-VSP Phase I multi-center, multinational, open label, dose escalation clinical trial.
Dieters trying to stick to their diets may want to look no further than lean protein, according to two studies published in the prestigious journal Obesity. Including protein such as lean pork in three daily meals could reduce late-night desires to eat, increase feelings of fullness and decrease distracting thoughts about food, according to the research.
A medical device developed by retired U.S. Navy sonar experts, using submarine technology, is a new paradigm for the detection, diagnosis and monitoring of stroke, says a team of interventional radiologists at the Society of Interventional Radiology's 36th Annual Scientific Meeting in Chicago, Ill.
A comprehensive new review published in the journal Respirology indicates that lung problems are major causes of morbidity and mortality following natural disasters.
As the American military rushes to confront adversaries in some of the world's highest mountain ranges, the Department of Defense is giving $4 million to the Altitude Research Center at the University of Colorado School of Medicine to develop revolutionary ways to combat high altitude sickness in soldiers, sailors and marines.
Cleveland Medical Devices Inc. (CMDI) has announced the formation of Great Lakes NeuroTech (www.GLNeuroTech.com), a spin-off company which has acquired the rights to develop, market, and manufacture clinical motor assessment and therapy systems for the movement disorders market as well as physiological monitors for research and education markets. Great Lakes NeuroTech (GLN) will perform R&D, engineering, manufacturing, distribution, and exporting of these technologies through two divisions: Movement Disorders and Research & Education Systems.
University of Utah scientists used invisible infrared light to make rat heart cells contract and toadfish inner-ear cells send signals to the brain.
Researchers seeking to unravel the most ancient yet least understood of the five senses - smell - have discovered a previously unknown step in how odors are detected and processed by the brain.
A research team at the University of Colorado Cancer Center has identified an enzyme that could be used to diagnose colon cancer earlier. It is possible that this enzyme also could be a key to stopping the cancer.
A group of scientists at Marshall University is conducting research that may someday lead to new treatments for repair of the central nervous system.
Researchers exploring human metabolism at the University of California, San Francisco have uncovered a handful of chemical compounds that regulate fat storage in worms, offering a new tool for understanding obesity and finding future treatments for diseases associated with obesity.
Neuroscientists and engineers at UCSF and UC Berkeley have joined forces to help pioneer a new frontier of brain repair - the development of devices that would allow patients with such conditions as stroke, spinal cord injury, traumatic brain injury and Lou Gehrig's disease to control prosthetics through thoughts alone.
A new study has shown that people who frequently attend religious services are significantly more likely to become obese by the time they reach middle age. The finding is surprising especially considering that religious people tend to be in better health than others, said study author Matthew J. Feinstein, a medical student at Northwestern University in Chicago. Feinstein said, “It highlights a particular group that appears to be at a greater risk of becoming obese and remaining obese…It's a group that may benefit from targeted anti-obesity interventions and from obesity prevention programs.”
Doctors at the Texas Heart Institute at St. Luke's Episcopal Hospital have successfully implanted the first continuous-flow total artificial heart in a desperately ill patient facing imminent death.
Dr. Michael Hayden, a Xenon founder and Chief Scientific Officer, has received the Canada Gairdner Wightman Award for leadership in medical science in Canada.
