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.
Researchers report they have created pigs that produce omega-3 fatty acids, which are known to improve heart function and help reduce the risks for heart disease, representing the first cloned transgenic livestock in the world that can make the beneficial compound.
Researchers in the U.S. have created pigs that produce omega-3 fatty acids, which are believed to improve heart function and help reduce the risks for heart disease.
A recent study from Scandinavia shows that the well-known differences between individuals in the efficiency of converting energy stored in food to work done by muscles are related to muscle fibre type composition and to the content of specific molecules in muscle.
The experiment provides a new and intriguing illusion that sheds light on how we learn to move accurately, as well as indicating why some people who have had limbs amputated still feel as if they can move their 'phantom' limb.
Researchers at the University at Buffalo and the University of Pennsylvania were the first to demonstrate that two intracellular events, both stimulated by the same cell receptor, can provoke different behaviors in mammals.
Patients experiencing high normal blood pressure (HNBP), a precursor to hypertension, may benefit from early treatment with pharmacological therapy, according to new research presented at the American College of Cardiology's 55th Annual Scientific Session.
The research identifies a transporter, encoded by the gene, as a potential target for drugs to boost oxalate secretion in the gut and help prevent kidney stones, said Peter Aronson, M.D., professor of internal medicine and physiology and senior author of the research.
Thiazolidinediones (TZD's) are drugs commonly prescribed to patients with type 2 diabetes, the most common form of diabetes. Current U.S. Food and Drug Administration-approved agents are known as Actos (pioglitazone) and Avandia (rosiglitazone).
The development gives researchers insights into how hearts develop in living mouse embryos and could improve our understanding of irregular heartbeats, known as arrhythmias, as well as open doors to observing cellular processes to better understand basic physiology and disease.
Two new studies in the March Cell Metabolism reveal a survival mechanism by which cells adapt to oxygen starvation by ratcheting down their demand.
The study showed that bone marrow derived cells can differentiate into functional gastrointestinal epithelial cells after bone marrow transplantation.
The IST project SENSATION is an ambitious project of 46 partners from 20 different countries, addressing sensing of physiological parameters, core computation, medical and industrial research.
A new study reinforces the growing body of evidence on health disparities between men and women and may possibly shed light on why socially isolated men are more vulnerable to disease and death than isolated women.
Bacteria are bad. Mothers and doctors, not to mention the cleaning product industry, repeatedly warn of their dangers. But a Stanford University School of Medicine microbiologist is raising the intriguing idea that persistent bacterial and viral infections have benefits.
Though many parents may never have heard of it, a severe and chronic condition called eosinophilic esophagitis (EE) is recognized by doctors as an emerging health problem for children.
Researchers at the University of Virginia Health System have identified a molecular target, or receptor, for potential drugs to treat acute respiratory distress syndrome (ARDS), a sudden and life-threatening failure of the lung.
Fifty years after MIT researchers pioneered the use of electron microscopy to study viruses, MIT scientists have helped produce the most detailed images yet of the tiny infectious agents.
In the journal Cell, researchers report new evidence to explain why prostate cancer and other hormone-dependent cancers may become resistant to hormone therapies.
University of South Florida researcher Barbara Hansen, PhD, will likely never be invited to talk about weight loss on Oprah. Her message is mundanely common sense, not faddish - she doesn't drop phrases like "low carb," or "low fat," or "geared to your body type" or "put your body into fat-burning mode."
According to a researcher in the U.S. losing and keeping off weight requires a lifelong commitment and effort.
