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.
An international research consortium developed, with significant involvement of Luxembourg Centre for Systems Biomedicine scientists, the first computer model to include 3D in the representation of human metabolic processes.
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, causes lethal respiratory paralysis within several years of diagnosis. There are no effective treatments to slow or halt this devastating disease.
Constrictions of the coronary blood vessels is a possible consequence of type 1 diabetes, and one that can eventually lead to myocardial infarction or heart failure.
Deep in the middle of our heads lies a tiny nub of nerve cells that play a key role in how hungry we feel, how much we eat, and how much weight we gain. Around the clock, they produce a "grandfather" form of several hormones that help us regulate these crucial functions.
New research on why the influenza vaccine was only modestly effective in recent years shows that immune history with the flu influences a person's response to the vaccine.
Every cell in your body responds to the hormone insulin, and if that process starts to fail, you get diabetes. In an unexpected finding, scientists at Joslin Diabetes Center have identified four viruses that can produce insulin-like hormones that are active on human cells.
New research published in The Journal of Physiology could open the door to new therapies to improve the movement of arms and hands of stroke survivors.
Researchers who analyzed data from the UK's National Pregnancy in Diabetes Audit found concerning shortcomings in pregnancy preparation and prenatal care for women with diabetes. In addition, significant clinic-to-clinic variation across the England and Wales suggests opportunities for improvement.
Biomedical engineers at Case Western Reserve University are growing tracheas by coaxing cells to form three distinct tissue types after assembling them into a tube structure-;without relying on scaffolding strategies currently being investigated by other groups.
The skeleton is often seen as an inert tissue, but this perception is quite wrong. In fact, the skeleton is constantly being remodeled: old bone fragments are broken down and new bone matrix is deposited, overall leading to a completely renewed skeleton every ten years.
Scientists at Imperial College London have become the first in the world to test how pathogens interact with artificial human organs.
Most people agree that getting a little exercise helps when dealing with stress. A new BYU study discovers exercise -- particularly running -- while under stress also helps protect your memory.
Consumption of a ketone supplement lowers blood sugar levels and may therefore help diabetics to control spikes in blood sugar, suggests a new study.
Dr. Castro is a translational oncologist with experience developing and harnessing nanotechnology and molecular imaging platforms for cancer purposes. His work offers a “less is more” approach — to generate robust cancer analyses using scant amount of specimens. Dr. Castro’s research has included funding from the V Foundation for Cancer Research, National Institutes of Health, Ovarian Cancer Research Fund, and the Department of Defense.
Scientists have identified a gene that may play a protective role in preventing heart disease. Their research revealed that the gene, called MeXis, acts within key cells inside clogged arteries to help remove excess cholesterol from blood vessels.
In findings that one day may help people sleep better, scientists have uncovered the first molecular evidence that two anciently conserved proteins in the brains of insects and mammals share a common biological ancestry as regulators of body temperature rhythms crucial to metabolism and sleep.
Schizophrenia and other psychiatric issues may be triggered by marijuana use, according to a research analysis in the Journal of the American Osteopathic Association.
Minutes after you eat a meal, as nutrients rush into your bloodstream, your body makes massive shifts in how it breaks down and stores fats and sugars.
Alzheimer´s disease is the key cause of dementia in elderly patients. Those affected develop deficiencies in their abilities to learn, think logically, communicate, and to master the challenges of everyday life.
Even if you haven't ridden your bike in years, you probably remember how to do so without giving it much thought.
