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 team of researchers has developed a wearable, non-invasive system to monitor electrical activity in the stomach over 24 hours--essentially an electrocardiogram but for the gastro-intestinal (GI) tract.
Maternal obesity and androgen excess induce sex-specific anxiety in the offspring, according to a study on mice by researchers at Karolinska Institutet in Sweden published in The FASEB Journal.
Sounds, photographs, light. Three elements are combined to create virtual nature spaces in Metla House, Joensuu. The famous wooden office building has housed innovative solutions since it was built. This time, the aim is to test virtual nature in practice and help budding enterprises find each other.
An international team of researchers led by John Landers, PhD, at UMass Medical School, and Bryan Traynor, MD, PhD, at the National Institute on Aging at the National Institutes of Health, has identified KIF5A as a new gene associated with the development of amyotrophic lateral sclerosis.
A unique cell surface protein found on triple-negative type breast cancer cells called JAG1 is a promising new therapeutic target for this hard-to-treat and highly metastatic type of breast cancer, according to researchers at the University of Illinois at Chicago.
Columbia University researchers have identified the nerve cells that initiate a fly's escape response: that complex series of movements in which an animal senses, and quickly maneuvers away from, something harmful such as high heat.
Minoxidil, a popular drug used on the scalp to treat hair loss, might improve blood flow to the brain, lower blood pressure and increase elasticity in the blood vessels if taken in an oral form, according to a new study in mice.
Heart patients who participate in cardiac rehab programs typically do well during enrollment but tend to revert to unhealthy lifestyles once the formal gym-based regimens end.
For the first time, researchers have produced a nearly complete three-dimensional structure for the yeast Nuclear Pore Complex. This discovery represents a major step toward identifying the atomic structure of the NPC, which soon may provide researchers with a better understanding of how the central transport channel functions.
Two University of Houston scientists are reporting that defects in a portion of the brain's hippocampus, called the dentate gyrus, is regulated by the nuclear receptor LXRβ (Liver X receptor Beta). The dentate gyrus, or DG, is responsible for emotion and memory and is known to be involved in autism spectrum disorders (ASD).
According to latest research, the muscle wasting that is associated with ageing has been attributed to loss of nerves. Researchers from the Manchester Metropolitan University, The University of Manchester, The University of Waterloo in Ontario, and Central Manchester University Hospitals NHW Foundation Trust published their study findings in the latest issue of The Journal of Physiology.
Doctors evaluating patients for blockages in the heart are aided by having a good roadmap of the vascular terrain before they can insert stents to clear the impasse.
A new study has helped to shed light on the process underlying muscle loss in old age, a condition that increases people’s risk of frailty and disability.
New research suggests that certain areas of the lungs are more likely than others to show age-related damage that compromises respiratory function. The paper is published ahead of print in the American Journal of Physiology-;Lung Cellular and Molecular Physiology.
Cardiovascular physiology researcher Victoria Claydon's latest study, published in the Journal of Neurotrauma, focuses on the results of her multi-national study, which surveyed almost 300 participants with spinal cord injuries at or above the mid-thoracic level (middle of the chest ).
OHSU physicians and researchers are developing what they hope will be the first permanent total artificial heart, which could provide the approximately 75,000 Americans who die of heart failure every year another chance at life.
In a recent study, scientists found that when exposed to another individual’s stress, the brain reacts as it does to real stress.
Pancreatic cancer is one of the less common but deadliest cancers. Modified oncolytic adenoviruses represent an alternative to chemotherapy and targeted therapies, which have a high mortality rate.
Researchers have identified a protein in saliva (histatin-5) that protects the body from traveler's diarrhea.
A new study has found that exposure to bright light before bed time inhibits the production of sleep-promoting hormone, melatonin, in preschoolers.
