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.
A research team led by Dr. Tony Lam at the Toronto General Research Institute and the University of Toronto discovered a novel function of a hormone found in the gut that might potentially lower glucose levels in diabetes.
Divers who held their breath for several minutes had elevated levels of a protein that can signal brain damage, according to a new study from the Journal of Applied Physiology. However, the appearance of the protein, S100B, was transient and leaves open the question of whether lengthy apnea (breath-holding) can damage the brain over the long term.
Day after day of chronic stress will wear a person down physically and mentally. But new research suggests that the acute stress produced by a brief run-in with a stressful scenario acts on a key brain region controlling emotion and cognition, temporarily improving learning and memory.
A new study by scientists at the University of Iowa shows why muscle membranes don't rupture when healthy people exercise.
The same mechanism that helps you detect bad-tasting and potentially poisonous foods may also play a role in protecting your airway from harmful substances, according to a study by scientists at the University of Iowa Roy J. and Lucille A. Carver College of Medicine.
Experiencing chronic stress day after day can produce wear and tear on the body physically and mentally, and can have a detrimental effect on learning and emotion. However, acute stress -- a short stressful incident -- may enhance learning and memory.
Miglustat is a drug currently under phase 2 clinical trials on patients suffering from cystic fibrosis (1). Its potential for treating the disease was discovered in 2006 thanks to the work of Frédéric Becq's team at the Institute of Cell Physiology and Biology (CNRS/Université de Poitiers), funded by the associations Vaincre la Mucoviscidose, MucoVie66, La Pierre Le Bigaut and ABCF2.
Mothers of premature infants shouldn't rely solely on breast pumps to establish and maintain their breast milk supply, researchers at Lucile Packard Children's hospital and the Stanford University School of Medicine have found. Moms already have a simple, safe and free tool for assisting breast milk production: their own hands.
Researchers at the Sahlgrenska Academy, Gothenburg, have discovered a new brain mechanism involved in alcohol addiction involving the stomach hormone ghrelin. When ghrelin’s actions in the brain are blocked, alcohol’s effects on the reward system are reduced. It is an important discovery that could lead to new therapies for addictions such as alcohol dependence.
It could mean the end of animal testing and eventually even clinical patient drug trials. The Virtual Physiological Human is a 21st century pan-European project that’s gaining momentum and takes a major step forward this week at The University of Nottingham.
Blood flow and respiratory rates can synch with music, indicating that music could one day be a therapeutic tool for blood pressure control and rehabilitation, according to a study by Italian researchers published in Circulation: Journal of the American Heart Association.
Researchers at the Johns Hopkins School of Medicine have successfully edited the genome of human- induced pluripotent stem cells, making possible the future development of patient-specific stem cell therapies. Reporting this week in Cell Stem Cell, the team altered a gene responsible for causing the rare blood disease paroxysmal nocturnal hemoglobinuria, or PNH, establishing for the first time a useful system to learn more about the disease.
Having partnered last year with an international team that surveyed the genomes of 12,000 individuals to find a genetic cause for gout, Johns Hopkins scientists now have shown that the malfunctioning gene they helped uncover can lead to high concentrations of blood urate that forms crystals in joint tissue, causing inflammation and pain - the hallmark of this disease.
Jeffrey M. Friedman, Marilyn M. Simpson Professor and head of the Laboratory of Molecular Genetics at Rockefeller University, has received the 2009 Shaw Prize in Life Science and Medicine. The prize was announced today by the Hong Kong-based Shaw Prize Foundation.
A team of researchers led by Dr. Jayakrishna Ambati at the University of Kentucky has discovered a biological marker for neovascular age-related macular degeneration (AMD), the leading cause of blindness in older adults.
Researchers at the University of North Carolina at Chapel Hill School of Medicine in collaboration with lead investigators at the University of Kentucky have identified a new target for the diagnosis and treatment of age-related macular degeneration, the most common cause of blindness in older Americans.
Researchers at Boston University School of Medicine (BUSM), the Naval Medical Research Center and the National Institutes of Health, have solved the structure of thin hair-like fibers called "pili" or "fimbriae" on the surface of bacteria that cause traveler's diarrhea.
In a new study appearing online this week in the Proceedings of the National Academy of Sciences, Dr. Liu and his co-workers have found that this mold, which uses a protein called FRQ as the main gear of its clock, marks time by a sequence of changes in the protein's chemical structure.
According to researchers at McMaster University, exposure of the fetus to nicotine results in the inability to respond to decreases in oxygen - known as hypoxia - which may result in a higher incidence of SIDS.
Researchers at McGill University and the University of Pennsylvania have discovered that a widely used anti-diabetic drug can boost the immune system and increase the potency of vaccines and cancer treatments. Their findings will be published June 3 in the journal Nature.
