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.
Overeating has been found to impair blood sugar (glucose) control and insulin levels. A new study suggests that the duration of a bout of overeating can affect how the body adapts glucose and insulin processing when calorie intake increases.
Chronic obstructive pulmonary disease is characterized by a chronic airflow obstruction that is associated with severe global mortality and morbidity.
Moving the clock forward and then back each spring and fall usually draws plenty of complaints and questions about why such a change is necessary.
With nearly $4 million in funding from the National Institute of Arthritis & Musculoskeletal & Skin Diseases, the University of California, Irvine will establish the UCI Skin Biology Resource-based Center.
Using a unique computational "framework" they developed, a team of scientist cyber-sleuths in the Vanderbilt University Department of Molecular Physiology and Biophysics and the Vanderbilt Genetics Institute has identified 104 high-risk genes for schizophrenia.
Two papers appearing April 18 in the journal Cell Metabolism confirm that the circadian clock is an important factor in how the body responds to physical exertion.
A scientific breakthrough provides new hope for millions of people living with multiple sclerosis. Researchers at Oregon Health & Science University have developed a compound that stimulates repair of the protective sheath that covers nerve cells in the brain and spinal cord.
A prescribed drug to treat high blood pressure has shown promise against conditions such as Parkinson's, Huntington's and forms of dementia in studies carried out in mice and zebrafish at the University of Cambridge.
A new study led by researchers from the University of California, Irvine finds exercising in the morning, rather than at night, may yield better results.
The timing of food intake is a major factor driving the rhythmic expression of most genes in the mouse liver, researchers report April 16 in the journal Cell Reports.
Oxidants found within living organisms are byproducts of metabolism and are essential to wound-healing and immunity.
An initial gene analysis may yield better outcomes when patients are treated with the antipsychotic drugs risperidone and aripiprazole.
The scientific community has long held an understanding about the effect of temperature on sperm production in mammals, but this new study sheds light on how spermatogenesis in insects is hampered at extreme temperatures.
A review led by a sports scientist at the University of Stirling has set out new international guidelines for protein intake in track and field athletes.
UC San Francisco scientists have designed a large-scale screen that efficiently identifies drugs that are potent cancer-killers when combined, but only weakly effective when used alone.
Labs are demanding purity and flexibility for high throughput nucleic acid purification, while needing to complete difficult downstream analysis, for example with Next Gen Sequencing (“NGS”)
Soon after conception, an embryo's circulatory system connects to that of its mother. Complications that occur at this critical time can result in miscarriage or birth defects with long-term chronic conditions.
On a normal day, the cells of a human liver do what they do best - making key blood proteins, clearing toxins from the blood and sending their remains down the digestive tract in a never-ending stream of bile.
In a study published in Science Advances magazine, researchers from the University of California, Irvine have captured, for the first time, the full-length structure of the rod photoreceptor phosphodiesterase 6 (PDE6), an enzyme that plays an indispensable role in human vision.
Alterations in functional connectivity of the brain may help in understanding the neurobiological changes leading to somatic symptom disorder, reports a study in Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society.
