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 type of antibiotic that can cause hearing loss in people has been found to paradoxically protect the ears when given in extended low doses in very young mice.
A new study has found that Vitamin D, readily available in supplements or cod liver oil, can counter the effects of Crohn's disease. John White, an endocrinologist at the Research Institute of the McGill University Health Centre, led a team of scientists from McGill University and the Universit- de Montr-al who present their findings about the inflammatory bowel disease in the latest Journal of Biological Chemistry.
Two new studies by researchers at the University of Washington further our understanding of the molecular steps in the PLC cascade, a G protein-coupled receptor signaling mechanism that underlies a wide variety of cellular processes, including egg fertilization, hormone secretion, and the regulation of certain potassium channels.
Antioxidants increasingly have been praised for their benefits against disease and aging, but recent studies at Kansas State University show that they also can cause harm.
Curemark, LLC, a drug research and development company focused on the treatment of neurological diseases, announced that the company is now enrolling patients in Phase III clinical trials for CM-AT, its autism treatment, at ten sites across the country.
Jamaican sprinter Usain Bolt's record-setting performances have unleashed a wave of interest in the ultimate limits to human running speed. A new study published in the Journal of Applied Physiology offers intriguing insights into the biology and perhaps even the future of human running speed.
Retinoblastoma is a pediatric eye cancer initiated by the loss or mutation of both copies of the retinoblastoma gene. Current evidence suggests that additional genetic alterations are required for retinoblastoma to become fully malignant.
People with chronic-obstructive pulmonary disease (COPD) often find themselves in a downward spiral when it comes to their health. COPD, which includes chronic bronchitis and emphysema, means that the elasticity of the lungs is destroyed.
Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, today announced the publication of new data in the journal Nature Biotechnology by Alnylam scientists and collaborators from Tekmira Pharmaceuticals Corporation, AlCana Technologies, Inc., and The University of British Columbia (UBC). The new study employed a rational design approach for the discovery of novel lipids that can be incorporated into lipid nanoparticles (LNPs) for systemic delivery of RNAi therapeutics.
Gently rocking embryos while they grow during in vitro fertilization (IVF) improves pregnancy rates in mice by 22 percent, new University of Michigan research shows. The procedure could one day lead to significantly higher IVF success rates in humans.
University at Buffalo researchers are the first to show that a controlled individualized exercise training program can bring athletes and others suffering with post-concussion syndrome (PCS) back to the playing field or to their daily activities.
Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, today announced that it presented data from multiple pre-clinical and clinical programs at the “RNA Silencing: Mechanism, Biology, and Application” Keystone Symposium held January 14-19, 2010 in Keystone, Colorado. Alnylam and its collaborators presented data from Alnylam’s therapeutic programs including transthyretin (TTR)-mediated amyloidosis and Huntington’s disease, as well as new data on delivery approaches for the systemic delivery of RNAi therapeutics.
iWorx, a developer of advanced physiology research and teaching tools, has launched a family of cardiovascular research products used to assess cardiac performance and hemodynamics, both in vivo and in vitro.
The Journal of Biological Chemistry's editors are unveiling this week a number of changes to the journal's publishing policies. They say the changes are in response to the increasingly interdisciplinary nature of biological research and will help the journal better meet the evolving needs of the scientific community.
JSerra Catholic High School and Mission Hospital announced a Pre-Med Professional Magnet program designed for students interested in careers in medicine and healthcare.
Gently rocking embryos while they grow during in vitro fertilization (IVF) improves pregnancy rates in mice by 22 percent, new University of Michigan research shows. The procedure could one day lead to significantly higher IVF success rates in humans.
Sirnaomics, Inc. (www.sirnaomics.com) announced today that the company has licensed a polypeptide nanoparticle technology invented by Professor A. James Mixson of University of Maryland Medical School.
An enzyme that normally helps break down stored fats goes into overdrive in some cancer cells, making them more malignant, according to new findings by a team at The Scripps Research Institute.
Scientists at the Gladstone Institute of Neurological Disease (GIND) have identified the reason a key protein plays a major role in two neurodegenerative diseases.
"We are very happy to be donating money to the fight against breast cancer, especially in light of our own family history," says M-rit Rausing. "Hans's mother and grandmother both died of the disease, and his father, Ruben, put considerable effort into finding a cure. Of course, it's also important when you think that breast cancer is one of the most common diseases."
