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.
Penn study sheds new light on biology of fatty liver disease

Penn study sheds new light on biology of fatty liver disease

A new appreciation for the interplay between two cell nucleus proteins that lead both intertwined and separate lives is helping researchers better understand fatty liver disease, according to a new study by researchers at the Perelman School of Medicine at the University of Pennsylvania. [More]

Large study of familial ALS finds new gene variant present in 3% of all patients with disease

Variations in a gene with multiple functions in neurons are present in approximately 3 percent of all cases of ALS in North American and European populations, both sporadic and familial, making it one of the most common genetic causes of the disease, according to a paper published in Nature Genetics.

Rat study finds maternal intake of oxidised fish oil causes high newborn mortality

Nearly 30 percent of newborn pups born to pregnant rats fed highly oxidized ("off") fish oil died within two days after birth a new study by researchers at the Liggins Institute at the University of Auckland in New Zealand finds. [More]
Long-term antibiotic treatment slows progression of Alzheimer's disease through changes in gut bacteria

Long-term antibiotic treatment slows progression of Alzheimer's disease through changes in gut bacteria

Long-term treatment with broad spectrum antibiotics decreased levels of amyloid plaques, a hallmark of Alzheimer's disease, and activated inflammatory microglial cells in the brains of mice in a new study by neuroscientists from the University of Chicago. [More]

Noninvasive brain stimulation may curb cravings for appetitive foods

Noninvasive brain stimulation may curb cravings for appetitive foods

Available research suggests that noninvasive stimulation of a specific brain area can reduce food cravings—particularly for high-calorie, "appetitive" foods, according to a review in the Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society. The journal is published by Wolters Kluwer. [More]

Preventing sudden unexpected deaths of babies and children: an interview with Professor Peter Fleming

Preventing sudden unexpected deaths of babies and children: an interview with Professor Peter Fleming

SIDS is the sudden and unexpected death of a baby, which usually occurs during sleep. The great majority of the babies are aged between about two weeks and seven or eight months. [More]
Biologists develop new method for analyzing brain regions

Biologists develop new method for analyzing brain regions

Using the example of the fruit fly, a team of biologists led by Prof. Dr. Andrew Straw has identified patterns in the genetic activity of brain cells and taken them as a basis for drawing conclusions about the structure of the brain. [More]

Changes in cavefish metabolism could lead to new insights into diabetes

Cavefish that live in dark caves with only sporadic access to food show symptoms similar to diabetes, but don't appear to experience any health problems. [More]
Low levels of blood selenium may increase risk of liver cancer

Low levels of blood selenium may increase risk of liver cancer

A new study, published in current issue of The American Journal of Clinical Nutrition, shows that the highest levels of blood selenium or of selenoprotein P, the protein that distributes selenium from the liver around the body, are associated with a decreased risk of developing liver cancer (particularly hepatocellular carcinoma), even when all other major liver cancer risk factors are taken into account.
