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.
Unlike humans, honey bees, when thrown into highly time-altered new societal roles, are able to alter their biological rhythms with alacrity, enabling them to make a successful "quick switch" in their daily routines, according to research carried out at the Hebrew University of Jerusalem.
A University of Missouri researcher believes his latest work moves scientists closer to a cure for cystic fibrosis, one of the world's most common fatal genetic diseases.
Mayo Clinic radiologist and researcher Richard Ehman, M.D., has been named by the National Academy of Sciences to the Institute of Medicine. Selection to the Institute (one of the four Academies, based in Washington, D.C.) is one of the highest honors in medicine in the United States.
Leading national researchers in the fight against breast cancer will convene Oct. 26-29 for the 2010 Advances in Breast Cancer Research Workshop at the University of Arkansas. More than 70 scientists from diverse research areas in science, medicine, engineering and technology will participate. Ten featured speakers will present cutting-edge research on breast cancer diagnosis, therapeutic techniques, treatment and screening.
Deaf or blind people often report enhanced abilities in their remaining senses, but up until now, no one has explained how and why that could be. Researchers at The University of Western Ontario, led by Stephen Lomber of The Centre for Brain and Mind have discovered there is a causal link between enhanced visual abilities and reorganization of the part of the brain that usually handles auditory input in congenitally deaf cats. The findings, published online in Nature Neuroscience, provide insight into the plasticity that may occur in the brains of deaf people.
The La Jolla Institute for Allergy & Immunology will develop San Diego's first Center for RNAi screening -- a breakthrough genomics technology that will further enhance San Diego's reputation as a national research leader and provide the local biomedical community ready access to the Nobel-Prize winning technology.
The first study to demonstrate that obesity can directly accelerate the progression of acute lymphoblastic leukemia (ALL) has been conducted at The Saban Research Institute of Childrens Hospital Los Angeles and was published in Cancer Prevention Research, on October 5, 2010.
Researchers at the University of Illinois at Chicago College of Medicine have found how gene expression that may contribute to drug resistance is ramped up in unusual types of breast tumors. Their findings may offer new therapy targets.
A deficiency in one of the immune system's enzymes affects the severity of autoimmune diseases such as MS, and explains why the course of these diseases can vary so much. New findings give an insight into how this enzyme deficiency can be diagnosed, and could lead to new medicines, reveals a thesis from the Sahlgrenska Academy.
With the help of tiny, see-through fish, Stanford University School of Medicine researchers are homing in on what happens in the brain while you sleep. In a new study, they show how the circadian clock and sleep affect the scope of neuron-to-neuron connections in a particular region of the brain, and they identified a gene that appears to regulate the number of these connections, called synapses.
Just as intense concentration allows a sharp mind to perform at its peak, a research institute that concentrates pre-eminent scientists from 11 academic departments can push back the frontiers of knowledge in a complex research area: the human brain.
NephRx Corporation today announced that a new study has shown that its novel peptide NX002 demonstrated significant efficacy when tested in an animal model of oral mucositis. Mucositis is a debilitating and often dose-limiting side effect of many forms of cancer therapy that affects more than 400,000 patients who receive chemotherapy or radiation treatment in the U.S. each year. Current treatment options are very limited.
People who have been blind from birth make use of the visual parts of their brain to refine their sensation of sound and touch, according to an international team of researchers led by neuroscientists at Georgetown University Medical Center (GUMC).
Scientists from The Scripps Research Institute have developed the first screening method that rapidly identifies individuals with active river blindness, a parasitic disease that afflicts an estimated 37 million people. The test could change the current strategy of mass treatment in areas where river blindness, also known as onchocerciasis, is suspected.
Yesterday's announcement that a pioneer of in vitro fertilization (IVF) for humans has won the Nobel prize for medicine three decades after his groundbreaking work adds new historical perspective to advancements in reproductive medicine, a sharp reminder of how a once-feared technology has transformed into a highly popular and routine treatment for infertility, said one of Southern California's earliest fertility doctors.
New neuroscience research by life scientists from UCLA and Australia may potentially help people who have lost their ability to remember due to brain injury or disease.
In a powerful demonstration of collective standing in the health care community, more than 40 organizations gathered on Capitol Hill to issue a call to action in reducing sudden cardiac arrest (SCA) deaths.
Preclinical data was published today on research performed by Cytori Therapeutics (NASDAQ:CYTX) showing adipose (fat)-derived stem and regenerative cells (ADRCs), either fresh or banked, demonstrated statistically significant improvements in animal survival and kidney function in an acute kidney injury animal model.
Knome, Inc. today announced the winners of its inaugural KnomeDISCOVERY Awards, a program designed to spur new genetic insights into health.
Scientists at the University of Bonn have altered cardiac muscle cells to make them controllable with light. They were thus able to use directed light to cause conditions such as arrhythmia in genetically modified mice. The method opens up completely new possibilities for researching the development of such arrhythmias. The study will be published in the upcoming edition of "Nature Methods".
