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 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.
Stress can change the balance of bacteria that naturally live in the gut, according to research published this month in the journal Brain, Behavior, and Immunity.
Till date all attempts to get drugs into the brain were countered by the blood-brain barrier - the natural defense against potentially harmful chemicals floating around the body. However this new finding from a team from University of Oxford shows that now scientists have successfully switched off a gene implicated in Alzheimer’s disease in the brains of mice by exploiting tiny particles naturally released by cells, called exosomes.
When Geoffrey Murphy, Ph.D., talks about plastic structures, he's not talking about the same thing as Mr. McGuire in The Graduate. To Murphy, an associate professor of molecular and integrative physiology at the University of Michigan Medical School, plasticity refers to the brain's ability to change as we learn.
The growing concern surrounding the release of radiation from an earthquake and tsunami-stricken nuclear complex in Japan has raised fears of radiation exposure to populations in North America from the potential plume of radioactivity crossing the Pacific Ocean.
Armed with a zebrafish model of Duchenne muscular dystrophy and a library of 1,200 chemicals already approved for human use, researchers at Children's Hospital Boston have identified a compound that reverses the loss of muscle structure and function associated with DMD, seemingly by compensating for the loss of a critical protein.
Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered that members of an enzyme family found in humans and throughout the plant and animal kingdoms play a crucial role in regulating cell motility. Their findings suggest an entirely new strategy for treating conditions ranging from diabetic ulcers to metastatic cancer.
A University of Greenwich lecturer's book could be the blueprint to produce a generation of super gymnasts.
A team of researchers at the Instituto Gulbenkian de Ci-ncia (IGC), Portugal, discovered that pollen, the organ that contains the plant male gametes, communicate with the pistil, their female counterpart, using a mechanism commonly observed in the nervous system of animals.
Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, is reporting the filing of a complaint by Tekmira Pharmaceuticals Corporation in the Business Litigation Session (BLS) of the Massachusetts Superior Court. The complaint alleges misappropriation and misuse of information, amongst other allegations.
In a recently-published study mapping the structure and function of the so-called "orphan" nuclear receptor TR4, Van Andel Research Institute (VARI) investigators suggest that Vitamin A may play a more direct role than was previously known in certain physiological functions including sperm cell formation and the development of the central nervous system.
On March 28, leading experts across multiple disciplines will convene at the 2nd World Congress on Interventional Therapies for Type 2 Diabetes to review the latest research on bariatric surgery as a treatment option.
It's been more than 20 years since scientists first discovered the gene that causes cystic fibrosis (CF), yet questions about how the mutated gene causes disease remain unanswered.
With the first U.S. implant of its new Activa SC neurostimulator for deep brain stimulation therapy, Medtronic, Inc. today announced the technology's commercial availability throughout the United States and Europe.
The Medical Imaging Laboratory in Trondheim is making advances in imaging methods for both ultrasound and magnetic resonance (MR) imaging. One benefit will be an enhanced ability to discover heart defects in newborns.
