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.
The brain hosts an extraordinarily complex network of interconnected nerve cells that are constantly exchanging electrical and chemical signals at speeds difficult to comprehend.
The Shakespeare Birthplace Trust has launched a brand new medical exhibition at Hall’s Croft, home of Shakespeare’s daughter Susanna and her physician husband, John Hall. Method in the Madness: Understanding Ourselves Then and Now explores medicine in the lifetime of Shakespeare’s son-in-law, John Hall (1575 – 1635), who lived at and practiced from Hall’s Croft.
With a series of new grants, Saint Louis University researchers will tackle the twin epidemics of diabetes and obesity by tapping into the potential of two nuclear receptors that control muscle metabolism.
A first-of-its-kind mouse model could lead to an understanding of how cerebral malaria infection leads to the development of epilepsy in children, and to the prevention of seizures.
Statin drugs are widely used to manage high cholesterol and reduce the risk of cardiovascular disease. But in a new review of more than 50 studies, researchers cite reductions in liver inflammation and improvements in other related factors as reasons why statins make good candidates for treating chronic liver disease.
One year after launching its unique 3D Cell Explorer (the first microscope able to look inside living cells without harming them, in 3D and real time), the EPFL spin-off reaches a new fundamental milestone for cell biology and microscopy and releases its latest pioneering product: the 3D Cell Explorer-fluo.
Osteoporosis affects more than 200 million people worldwide and is a serious public health concern, according to the National Osteoporosis Foundation.
A new rare muscle disorder has been identified by researchers at Ruhr-Universität Bochum. This hereditary disease is caused by a defect in the BICD2 gene that manifests itself in altered cellular transport processes in skeletal muscle cells.
Royal Philips today announced that the results from two large clinical trials comparing patient outcomes using instant wave-free ratio (iFR) and fractional flow reserve (FFR) in the diagnosis and treatment of heart disease have been published in the New England Journal of Medicine.
While more research is needed to confirm the findings published today in the FASEB Journal, the use of FITR could herald a fast and easy way to spot early signs of infection, cancer, and difficult to diagnose neurological conditions.
Lamprey are slimy, parasitic eel-like fish, one of only two existing species of vertebrates that have no jaw. While many would be repulsed by these creatures, lamprey are exciting to biologists because they are so primitive, retaining many characteristics similar to their ancient ancestors and thus offering answers to some of life's biggest evolutionary questions
Like almost all light-sensitive living beings, human beings follow biological rhythms set on a period of about 24 hours.
For patients experiencing angina (chest pain) or a heart attack, a new tool called instantaneous wave-free ratio (iFR) was equivalent to the currently-preferred tool, fractional flow reserve (FFR), in terms of incidence of major adverse events according to two studies presented at the American College of Cardiology's 66th Annual Scientific Session. The studies also showed iFR resulted in markedly less patient discomfort and reduced procedure-related adverse events compared to FFR.
New research suggests that GlycA, a newly identified blood marker, and C-reactive protein both independently predict major adverse cardiac events, including heart failure and death. Patients who have high levels of both biomarkers are at especially high risk.
An overactive molecular signal pathway in the brain region of the amygdala can lead to obsessive-compulsive disorder (OCD). A research team from Würzburg has established this connection.
New Michigan State University research has found that refugees diagnosed with post-traumatic stress disorder regulate stress differently than those who don't have the disorder, but may have experienced similar suffering.
Researchers at Cardiff University have devised a new way of creating a drug commonly used as the first line of defence against malaria around the world.
Researchers at Karolinska Institutet collaborating in the large-scale Karolinska Schizophrenia Project are taking an integrative approach to unravel the disease mechanisms of schizophrenia.
The continuous daylight conditions of summer in Antarctica are known to interfere with physiological functions such as sleep patterns and the release of melatonin, a hormone associated with circadian rhythms and sleep.
Climbing above 4,000m can provoke abnormal heart rhythms in otherwise healthy mountaineers, with the abnormalities increasing with altitude, new research has shown.
