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.
New sleep research has shown that by respecting nature and keeping days light and nights dark we can improve our sleep patterns.
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.
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 Medical Center researchers have identified a gene that protects the gut from inflammatory bowel disease.
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.
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.
Researchers at Southern Methodist University in Dallas have developed a concise new explanation for the basic mechanics involved in human running.
One of the environmental factors that promote obesity, and the consequent health problems, are energy dense diets.
A pretest risk stratification enhanced by ultrasound of lung and venous performs better than Wells score in the early diagnostic process of pulmonary embolism (PE).
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.
Could something as simple as the geographic area in which you live contribute to your risk of developing heart disease and diabetes, or suffering a stroke? A new study, published in the open-access journal Frontiers in Physiology, has revealed that the incidence of Metabolic Syndrome could be linked to the altitude of where a person lives.
Global warming is expected to increase runoff and input of organic matter to aquatic ecosystems in large regions of the Northern hemisphere including the Baltic Sea.
A recent review of research suggests that changes to the microorganisms (microbiota) in the gastrointestinal (GI) tract may be a cause of irritable bowel syndrome (IBS).
Researchers at the University of Oslo and Oslo University Hospital have discovered that cancer cells grow by stealing energy from neighbouring cells.
More than $9 million in federal grants will help fund researchers in the Ohio State University Davis Heart and Lung Research Institute and their collaborators across the university campus to investigate new causes and treatments for cardiovascular disease.
The time of day that breast cancer chemotherapy drugs are given affects the amount of damaging inflammation in the body, a new study in mice suggests.
Improving dietary resilience and better integration of nutrition in the health care system can promote healthy aging and may significantly reduce the financial and societal burden of the "silver tsunami."
My group develops approaches to study cell-to-cell signaling in the brain – how the cells of the brain talk to each other. The brain is heterogeneous, probably more so than any other organ in our body, and many of its functions depend on the unique characteristics of these cells.
In a study to be presented Thursday, Jan. 26, in the oral concurrent session at 1:15 p.m. PST, at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting, researchers with the Université de Sherbrooke in Sherbrooke, Quebec, Canada will present their findings in a study titled, Reduction of total labor length through the addition of parenteral dextrose solution in induction of labor in nulliparous: results of DEXTRONS prospective randomized controlled trial.
The views among physicians and the general public when it comes to deciding whether to withhold or withdraw treatment of terminally ill patients differ greatly.
