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.
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.

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.
Exercise enthusiasts often wonder whether it's better to eat or fast before a workout. A new study is the first of its kind to show the effects of eating versus fasting on gene expression in adipose (fat) tissue in response to exercise.
For a few years, running has been fashionable. But there is a great difference between the physical demands of running a few kilometres and doing a marathon. Now Spanish researchers have concluded that genetics plays an essential role in success when completing this long distance.
When scientists talk about laboratory stem cells being totipotent or pluripotent, they mean that the cells have the potential, like an embryo, to develop into any type of tissue in the body.
Infection with reovirus, a common but otherwise harmless virus, can trigger the immune system response to gluten that leads to celiac disease, according to new research from the University of Chicago and the University of Pittsburgh School of Medicine.
Investigators at the Ted Rogers Centre for Heart Research have discovered a surprising new role for tumor necrosis factor (TNF): namely, that it is a major regulator of small blood vessel function, the key determinant of blood pressure. The study is published online today in Nature Communications.
Scientists have determined unexpected characteristics of a key protein linked to blood pressure control and to nerve growth, pain control and heart tissue regeneration. The findings, published April 5 online in the journal Nature, opens doors to potential new therapies to control cardiovascular disease and pain.
The Naomi Berrie Diabetes Center at Columbia University Medical Center has launched an initiative to study the relationship between the brain and metabolic disorders such as obesity and diabetes.
A team of researchers in France, led by Dr. Ana Buj-Bello (Genethon/Inserm) and teams at the University of Washington and Harvard Medical School in the United States, achieved a new step towards the treatment of myotubular myopathy by gene therapy.
Eating potassium-rich foods like sweet potatoes, avocados, spinach, beans, bananas -; and even coffee -; could be key to lowering blood pressure, according to Alicia McDonough, PhD, professor of cell and neurobiology at the Keck School of Medicine of the University of Southern California.
