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.

Natural dietary supplement tends to improve blood pressure and arterial health

Scientists have long known that restricting calories can fend off physiological signs of aging, with studies in fruit flies, roundworms, rodents and even people showing that chronically slashing intake by about a third can reap myriad health benefits and, in some cases, extend lifespan.

Simple bedside test may help doctors diagnose certain degenerative brain diseases

A simple bedside test that matches a change in heart rate with a drop in blood pressure after a patient stands may help doctors diagnose certain degenerative brain diseases.

Scientists demonstrate successful implementation of prosthetic memory system

Scientists at Wake Forest Baptist Medical Center and the University of Southern California (USC) have demonstrated the successful implementation of a prosthetic system that uses a person's own memory patterns to facilitate the brain's ability to encode and recall memory.

Realigning the brain clock to fit night shift patterns could result in better sleep, health

New research published in The Journal of Physiology shows that our brain clock can be shifted by light exposure, potentially to align it with night shift patterns.

International researchers present printed tattoo electrodes for long-term medical diagnostics

Electrodes for longterm monitoring of electrical impulses of heart or muscles in the form of temporary tattoos produced using an ink-jet printer. An international research group involving TU Graz, Austria, presents this novel method in Advanced Science.

SLU researchers turn off excruciating chemo pain in animal model

In a recent paper published in the journal Pain, Saint Louis University researchers describe their success in an animal model in turning off the excruciating pain that often accompanies a colorectal cancer drug.

Researchers develop wearable system to monitor electrical activity in the stomach over 24 hours

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 offspring, study suggests

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.

Virtual nature environment could be new way to recover from stress

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.

Discovery of new ALS gene points to cytoskeleton as potential target for drug development

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.

New DOD grant to support testing of promising therapy for triple-negative breast cancer

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 researchers identify nerve cells that drive fruit fly's escape behavior

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.

Study shows benefits of hair loss drug in improving cognitive function and vascular health

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.

Fitness trackers and virtual coaches motivate patients to exercise post cardiac rehab

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.

Researchers produce complete 3D structure for yeast Nuclear Pore Complex

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.

UH researchers improve understanding of autism spectrum disorders

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).

Muscle wasting of old age and ways to stop it understood in new study

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.

Newer non-invasive method provides cost savings for heart patients needing PCI

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.

12 Mar 2018

Researchers investigate protective systems that could reverse muscle loss in old age

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.

Aging and lung tissue stiffness contribute to function decline

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.
