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.
The relationship between head injuries suffered during contact sport and Alzheimer's disease is now being called into question thanks to research by the Sahlgrenska Academy, which has revealed that hockey players with multiple concussions probably have other injuries in their brains.
A midday jolt of caffeine isn't as powerful as walking up and down some stairs, according to new research from the University of Georgia.
Scientists at St. Boniface Hospital Albrechtsen Research Centre and the University of Manitoba have developed a drug that combats 2 of the top 10 "priority pathogens" recently defined by the World Health Organization as antiobiotic-resistant bacteria requiring new interventions.
Brown fat is a tissue well studied in small mammals, where it acts as a heat-producing organ to stay warm in a cold environment. Its unequivocal identification in adult, healthy humans about a decade ago is of major importance due to its immense capacity to convert chemical energy into heat
Scientists at The Scripps Research Institute in La Jolla have revealed new clues to the wiring of the brain. A team led by Associate Professor Anton Maximov found that neurons in brain regions that store memory can form networks in the absence of synaptic activity.
After her brain cancer became resistant to chemotherapy and then to targeted treatments, 26-year-old Lisa Rosendahl's doctors gave her only a few months to live.
Atrial fibrillation, an irregular heart rhythm that can cause an increased risk of stroke, affects approximately 2.2 million Americans each year. According to projections, that number is set to double in the next 25 years.
Researchers at the University of Maryland have identified how the pathogenic bacterium Pseudomonas aeruginosa uses tension-activated membrane channels to stop itself from swelling up and bursting when it is suddenly exposed to water.
Personalized workouts to prevent heart disease can be designed by a new digital instrument, according to research published today in the European Journal of Preventive Cardiology.
In experimental research, scientists tend to assume that -- unless they are looking specifically at reproduction or sexual behavior -- male and female animals are alike, and mostly use males.
Neurological disorders like Parkinson's, the aftermath of stroke, limb loss and paralysis significantly diminish the length and quality of life -- affecting about one in six people worldwide.
When you eat salty food, you get thirsty and drink water. Right? Maybe in the short-term, but within 24 hours, you actually get less thirsty because your body starts to conserve and produce more water.
According to research published online in The FASEB Journal, scientists have discovered a way to increase the amount of metabolism-boosting brown adipose tissue (BAT) ("good" fat) by employing two receptors on BAT cells as potential therapeutic targets.
The use of antipsychotic medication in nearly 100 Massachusetts nursing homes was significantly reduced when staff was trained to recognize challenging behaviors of cognitively impaired residents as communication of their unmet needs, according to a new study led by Jennifer Tjia, MD, MSCE, associate professor of quantitative health sciences.
For women who are overweight or obese and are unable to exercise, new research appearing online in The FASEB Journal suggests combining acupuncture with an electrical current may help.
DeNovix Inc., a US based manufacturer of instrumentation for bioresearch, is proud to announce the winner of a Special Edition Pink DS-11 FX+ Spectrophotometer / Fluorometer. The winner, randomly chosen from thousands of eligible entries to the company’s drawing, is Dr. Olena Livinska of the National Academy of Science of Ukraine.
A new position statement from the American Academy of Sleep Medicine asserts that the school day should begin at 8:30 a.m. or later for middle school and high school students.
Although GI disorders are among the most common medical conditions, many patients don't consider their symptoms serious enough to consult a physician and are left suffering in silence.
Researchers have found that the nerve cells (neurons) controlling sensation and movement of the hands show injury-induced changes for years after hand amputation, reattachment or transplant.
Time and again, fitness enthusiasts have a question–to exercise before or after breakfast. A new study published online in the American Journal of Physiology—Endocrinology and Metabolism has highlighted the role of fat toward metabolism. This is the first study that reveals the effects of fasting and feed status on human adipose tissue responses to exercise.
