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.

Sports-related concussion causes short-term impairment of cardiovascular system, study finds

A new study finds that concussion causes short-term impairment of the cardiovascular system but that these cardiovascular symptoms typically resolve within three days of the injury.

UMass Amherst discovery holds promise for revolutionizing treatment of cataracts and presbyopia

The University of Massachusetts Amherst recently licensed a new technology to Janssen Pharmaceuticals, Inc. that holds promise of revolutionizing the treatment of cataracts and presbyopia, based on early phase discoveries by polymer physicist Murugappan Muthukumar and former graduate student Ben Mohr regarding the fundamental science of proteins in the lens of the human eye.

MGH researchers develop novel approach to analyze brainwave activity during sleep

Massachusetts General Hospital investigators have developed a novel approach to analyze brainwaves during sleep, which promises to give a more detailed and accurate depiction of neurophysiological changes than provided by a traditional sleep study.

Quality of diet and multi-dimensional exercise training regimen can improve fitness

In two recent peer-reviewed papers published by Nutrients and Growth Hormone and IGF-1 Research, Skidmore College exercise scientist Paul Arciero and colleagues report proven benefits of consuming moderate amounts of protein regularly throughout the day (protein-pacing) combined with a multi-dimensional exercise regimen that includes resistance exercise, interval sprint exercise, stretching and endurance exercise.

Scientists show how immune receptor activated by bacteria contributes to diabetic bladder dysfunction

Bladder dysfunction is a reality for about half of patients with diabetes and now scientists have evidence that an immune system receptor that's more typically activated by bacteria is a major contributor.

Researcher paints pitiless picture of life for people with acquired deaf-blindness

It is like being in a dirty glass jar, unable to reach out and with acquaintances passing by without saying hello. New research from the Sahlgrenska Academy paints a merciless picture of life with acquired deaf-blindness.

Unhealthy gut microbes play role in development of high blood pressure in rats

Researchers have found that the microorganisms residing in the intestines (microbiota) play a role in the development of high blood pressure in rats. The study is published in Physiological Genomics. It was chosen as an APSselect article for February.

Changes in astronaut's gut microbes linked to spaceflight

Northwestern University researchers studying the gut bacteria of Scott and Mark Kelly, NASA astronauts and identical twin brothers, as part of a unique human study have found that changes to certain gut "bugs" occur in space.

Nicotine creates cascade of effects in the brain that get worse over time

The first period of nicotine abstinence proceeded as expected. The surprise came after three months when the lab rats suddenly became fearless and sought out well-lighted areas that prey animals normally avoid. At the same time, signaling in the brain's reward system changed, as shown by a study at Sahlgrenska Academy.

UT Southwestern scientists discover gene that protects gut from IBD

UT Southwestern Medical Center researchers have identified a gene that protects the gut from inflammatory bowel disease.

Prolonged exposure to high temperature decreases blood flow and limits exercise capacity

Researchers have found that prolonged exposure to high temperatures can raise both the skin and core temperature, reducing blood flow to the brain and limbs during exercise and limiting the ability to exercise for long periods.

‘Love hormone’ from insects could be used as drug lead to prevent uterine contractility in preterm labour

In a recent study published in "Scientific Reports", an international team of researchers led by MedUni Vienna report that an oxytocin-like neuropeptide ("inotocin") exhibited a specific pharmacological profile for the human receptors of oxytocin (known as the "love hormone") and vasopressin.

JAX researchers unravel mechanism that enables cancer cells to survive and divide

Some cancer cells have a trick up their sleeve to avoid cell death: boosting maintenance of telomeres, the protective "end caps" on chromosomes, and a research team led by Jackson Laboratory Professor Roel Verhaak reports in Nature Genetics on a newly discovered telomere maintenance mechanism.
