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.

RCSI-led study aims to train next generation of brain cancer researchers

A computational approach to map arrhythmia-related excitations

Atrial fibrillation is the most prevalent form of cardiac arrhythmia, affecting up to 6 million people in the U.S. alone. Common treatments for severe forms of the erratic beating phenomenon are controversial, and guided by detection methods that are not yet standardized or fully refined.

Reducing antioxidant levels in the colon may have positive effect on GI inflammation

A new study finds that lowering the levels of an antioxidant in the colon has an unexpectedly positive effect on gastrointestinal (GI) inflammation. The paper is published ahead of print in the American Journal of Physiology - Gastrointestinal and Liver Physiology.

Researchers use gene therapy to restore hearing and balance in mouse model of Usher syndrome

Hearing loss, sometimes associated with other disorders such as balance defects, is the most common sensory deficit, affecting more than 280 million people worldwide, according to WHO. In France, one child in 700 is born with severe or profound hearing loss, and one in every 1,000 will lose their sense of hearing before adulthood.

Study may contribute to genetic understanding of high-altitude adaptation

Many research groups have recently explored human adaptation and successfully identified candidate genes to high altitude living among three major far-flung global populations: Tibetans, Ethiopians and Peruvians.

Increased adrenaline levels in non-smokers’ hearts seen with the use of one e-cigarette with nicotine

A new study conducted at the University of California, Los Angeles, found that if non-smokers use one electronic cigarette that contains nicotine, they experience a rise in adrenaline levels in their heart; however, if the e-cigarette is nicotine-free, there was no increase in the levels of adrenaline.

Discovery reveals new role for endoplasmic reticulum-associated degradation

The discovery of a puddle of mouse urine seems like a strange scientific "eureka" moment. However, for one team of researchers, that's exactly what led to a new discovery.

Analytical Science in Precision Medicine

Pittcon is an analytical conference, so naturally my talk will be about analytical chemistry and how analytical chemistry will become increasingly important in delivering healthcare solutions, not only for rich people, but also, hopefully, for poor people across the world.

Combination of anti-malarial drug and photosensitizer could effectively kill cancer cells

Artemisinin, a potent anti-malarial drug, has been widely hailed as a promising alternative cancer treatment. Scientists from the National University of Singapore recently showed that its anti-cancer properties could be enhanced by 10 folds when used in combination with Aminolaevulinic acid, a photosensitizer or a drug which, upon exposure to light, leads to generation of free radicals that can kill cells.

KU Leuven researchers find that humans have lost ancient defense mechanism to combat viruses

Insects and plants have an important ancient defense mechanism that helps them to fight viruses. This is encoded in their DNA. Scientists have long assumed that vertebrates - including humans - also had this same mechanism. But researchers at KU Leuven, Belgium, have found that vertebrates lost this particular asset in the course of their evolution.

Research shows link between brain's immune system and desire to drink alcohol

Researchers from the University of Adelaide have found a new link between the brain's immune system and the desire to drink alcohol in the evening.

Electrical stimulation may help restore function in paralyzed patients

Nearly 282,000 people in the U.S. live with paralysis following a spinal cord injury (SCI). A review of more than 90 studies found that electrical stimulation may help restore function in those paralyzed after SCI. The article is published in Physiology.

Pharmaceutical compound from leaves of coralberry may help combat asthma

The coralberry could offer new hope for asthmatics: researchers at the University of Bonn have extracted a new kind of active pharmaceutical ingredient from its leaves to combat this widespread respiratory disease. In mice, it almost completely inhibits the characteristic contraction of the airways.

Brain activity found to be perturbed between seizures in childhood absence epilepsy

New research shows that in a mouse model of childhood absence epilepsy, brain activity is perturbed between seizures. The researchers speculate that this could underlie cognitive problems of the disease, which can persist despite treatment of seizures.
