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.
Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, announced today the publication of new research findings in the journal Proceedings of the National Academy of Sciences (PNAS) by Alnylam scientists and collaborators from Mount Sinai School of Medicine. In the new study, Alnylam and Mount Sinai scientists discovered a novel class of virus-produced small non-coding RNAs, called small viral RNAs (svRNAs), which play a critical role in the replication of influenza A virus.
There have been impressive advances in computational methods, allowing researchers to better understand biological and physiological systems at the atomic level. In its latest Perspectives in General Physiology series, the Journal of General Physiology (JGP) offers an in-depth look at several of these methods and the advantages of each as applied to membrane proteins, with special focus on ion channels.
University of Michigan scientists have provided the most detailed picture yet of a key receptor in the brain that influences the effectiveness of serotonin-related antidepressants, such as Prozac.
Scientists at the University of California, San Diego have identified a previously unknown kinase that regulates cell proliferation, shape and migration, and may play a major role in the progression or metastasis of cancer cells.
Patients with drug-resistant epilepsy run the risk of gradual deterioration in their cognitive abilities. Surgical treatment generally puts an end to seizures but can have a negative effect on memory. However, there is no further deterioration in memory, and some patients may even recover some of their memory capacity, reveals a thesis from the University of Gothenburg.
Researchers at Yale School of Medicine have discovered a method to select sperm with the highest DNA integrity in a bid to improve male fertility. The method is comparable to that of the egg's natural selection abilities, according to the study published in the June/July issue of the Journal of Andrology.
The bacterium Helicobacter pylori, which lives in the human stomach and is associated with ulcers and gastric cancer, is shaped like a corkscrew, or helix. For years researchers have hypothesized that the bacterium's twisty shape is what enables it to survive - and thrive - within the stomach's acid-drenched environment, but until now they have had no proof.
This research was developed by Dr. Enrique Garcia Artero, from the Department of Physiology of the University of Granada, and coordinated by Professor Manuel J. Castillo Garzón. To carry out this project, the researcher used data from the national and European projects AVENA (Food and Assessment of Nutritional Status of Spanish Adolescents) and HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence) and ALPHA (Assessing Levels of Physical Activity and Fitness; Public Health Executive Agency).
A Nobel Prize-winning University of Utah geneticist discovered that bone marrow transplants cure mutant mice who pull out their hair compulsively. The study provides the first cause-and-effect link between immune system cells and mental illness, and points toward eventual new psychiatric treatments.
Amgen Inc. today announced that the European Commission (EC) has granted marketing authorization for Prolia® (denosumab) for the treatment of osteoporosis in postmenopausal women at increased risk of fractures, and for the treatment of bone loss associated with hormone ablation in men with prostate cancer at increased risk of fractures.
For two decades, the laboratory mouse has been the workhorse of biomedical studies and the only mammal whose genes scientists could effectively and reliably manipulate to study human diseases and conditions.
Exercise can buffer the effects of stress-induced cell aging, according to new research from UCSF that revealed actual benefits of physical activity at the cellular level.
The Atlanta Journal Constitution reports that the Atlanta Technical College is expanding its health information technology program because demand for graduates is expected to grow by 20 percent through 2018.
Researchers from Boston University School of Medicine have shown that use of magnetic resonance imaging in an animal model can non-invasively identify dangerous plaques. The findings, which appear in the May issue of Circulation Cardiovascular Imaging, offer possible applications in the diagnosis and treatment of patients with atherosclerosis.
When the arteries delivering oxygen to our vital organs are obstructed by atherosclerosis or clots, the result is almost always a stroke, heart attack or damage to a peripheral tissue such as the legs (peripheral artery disease). But the severity of tissue injury or destruction from a choked-off blood supply varies from person to person, and may depend in large part on whose circulatory system has the best back-up plan to provide alternate routes of circulation.
Global scientific, technical, medical and scholarly publisher Wiley-Blackwell today announced the that its evidence-based clinical decision support product, Essential Evidence Plus, is now accessible from mobile devices. Physicians on the move can now easily find answers to challenging point-of-care questions from their iPhoneTM, IPod Touch-, AndroidTM, Blackberry- or other Smartphones.
The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) of the National Institutes of Health (NIH) has awarded Albert Einstein College of Medicine of Yeshiva University a five-year, $9.5 million grant for the continuation of its Diabetes Research and Training Center (DRTC). The DRTC was also awarded a $632,000 supplemental grant for equipment and additional pilot and feasibility studies through the American Recovery and Reinvestment Act (ARRA), bringing total NIH support to $10,177,000.
HSP10 (Heat Shock Protein), helps monitor and organise protein interactions in the body, and responds to environmental stresses, such as exercise and infection, by increasing its production inside cells. Researchers at Liverpool, in collaboration with colleagues at the University of California, found that excessive amounts of HSP10 inside mitochondria - 'organs' that act as energy generators in cells - can halt the body's ageing process by preserving muscle strength.
A DNA-vaccine that restricts the supply of blood to tumours has been developed by scientists at the Swedish medical university Karolinska Institutet. The vaccine slows the growth of breast cancer tumours in mice.
Volcano Corporation announced today the company's plans to highlight its new product launches, presence in live cases, and participation in late breaking trials during EuroPCR from May 25 – 28 in Paris.
