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.
Like skilled assassins, many diseases seem to know exactly what types of cells to attack.
Like skilled assassins, many diseases seem to know exactly what types of cells to attack. While decimating one cadre of cells, diseases will inexplicably spare a seemingly identical group of neighbors. What makes cells vulnerable or not depends largely on the kinds and amounts of proteins they produce - their 'translational profile,' in the lingo of molecular biology. For this reason, scientists have struggled to parse the subtle molecular differences among the hundreds of specialized cell types that are tangled together in tissues like the brain.
Brain cells can adopt a new chemical code in response to cues from the outside world, scientists working with tadpoles at the University of California, San Diego report in the journal Nature this week.
Scientists have shown for the first time that neuroprosthetic brain implants may be able to help stroke patients with partial paralysis.
It's a leading cause of death, but no one knows for sure how and why it happens. It's a major source of health care costs, adding days or weeks to the hospital stays and lost work time of millions of people. But no one fully understands how best to fight it.
Obese people who don't have high cholesterol or diabetes might think they're healthy - despite the extra pounds.
Australian scientists are suggesting that grape seeds may be a potential treatment in warding off Alzheimer's disease.
EMD Serono, Inc., an affiliate of Merck KGaA of Darmstadt, Germany, announced the launch of the Human Oocyte Preservation Experience (HOPE) Registry surrounding next week's 64th Annual Meeting of the American Society for Reproductive Medicine (ASRM).
These days most children born with congenital heart disease live well into adulthood, thanks to innovative surgical, interventional and medical treatments.
An international study showed testosterone, when used with no other hormone therapy, is an effective treatment for low libido in postmenopausal women.
Researchers at the University at Buffalo have found that fetuses of obese mother rats were programmed in utero to develop obesity in adulthood.
By injecting a hormone produced by fat and other tissues into mice, researchers report in the November Cell Metabolism that they significantly lowered blood sugar levels in normal and obese mice.
Researchers at the University at Buffalo have found that fetuses of obese mother rats were programmed in utero to develop obesity in adulthood.
A new study by two psychologists from the University of Rochester literally and figuratively attempts to address the question of what attracts men to women.
A groundbreaking study by two University of Rochester psychologists to be published online Oct. 28 by the Journal of Personality and Social Psychology adds color - literally and figuratively - to the age-old question of what attracts men to women.
New research funded by the British Heart Foundation (BHF) could pave the way for developing a test to predict pre-eclampsia in pregnant women and save the lives of mothers and babies across the world.
A University of Iowa study suggests that the prolonged fatigue after mild exercise that occurs in people with many forms of muscular dystrophy is distinct from the inherent muscle weakness caused by the disease.
Sneezing, runny nose and chills? You might blame the human rhinovirus (HRV), which causes 30 to 50 percent of common colds. But in reality, it's not the virus itself but HRV's ability to manipulate your genes that is the true cause of some of the most annoying cold symptoms.
Researchers from the University of Essex and medical counterparts from Colchester Hospital University NHS Foundation Trust are working together to develop successful partnerships in advancing medical research.
An international team of researchers has shown that mercury is another important factor in cardiovascular disease as it changes the way arteries work. One of the possible sources of exposure of humans to mercury is by eating contaminated fish.
