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.

Deep brain stimulation could help alleviate Parkinson’s symptoms on both sides of the body

For many patients with advanced Parkinson’s disease, deep brain stimulation can mean the difference between having difficulty walking and being able to run.

Researchers trim count of human genes to 20,000-25,000

Scientific description of the finished human genome sequence, reducing the estimated number of human protein-coding genes from 35,000 to only 20,000-25,000, a surprisingly low number for our species.

Study links possible role of ephedrine in sudden cardiac arrests

Each year 80,000 - 100,000 people in the U.S die suddenly from heart attacks without ever having had any symptoms of heart disease. In some cases, the victims of these unheralded sudden cardiac deaths had been taking dietary supplements containing ephedrine.

Researchers analyze the mechanisms and proteins that underlie mitochondria

New findings explaining the complicated process by which the "energy substations" of human cells split apart and recombine may lay the groundwork for new treatment approaches to a wide range of diseases, including some cancers and neurodegenerative diseases such as Parkinson's and Alzheimer's.

Researchers identifiy brain circuit that appears crucial in converting short-term memories into long-term memories

The circuit links the major learning-related area of the brain to another region that governs the brain's higher functions.

Balance between vasodilation and vasoconstriction in exercising muscle may change with age

The “fight or flight” mechanism is one of the best-known physiological responses. It increases our ability to respond to stressful situations. One way to look at exercise – physiologically -- is as a non-life-threatening example of a stressful situation.

Interleukin-6 has potential as a therapeutic drug in treating metabolic disorders such as obesity, type 2 diabetes and atherosclerosis

For the most of the past century, researchers have searched for a muscle-contraction-induced factor, which mediates some of the exercise effects in other tissues and organs such as the liver and adipose tissue.

Moderate exercise in mice after they were infected with influenza protects them from dying

University of Illinois researchers report that four consecutive days of moderate exercise in mice after they were infected with influenza protects them from dying, compared with mice that didn’t exercise.

Richard Axel has won the 2004 Nobel Prize in physiology or medicine

Richard Axel of the Columbia University Medical Center has won the 2004 Nobel Prize in Physiology or Medicine along with Linda B. Buck of the Fred Hutchinson Cancer Research Center for clarifying how the olfactory system works.

Linda Buck has been named winner of the 2004 Nobel Prize in physiology or medicine

Linda Buck, Ph.D., a member of Fred Hutchinson Cancer Research Center's Basic Sciences Division, has been named winner of the 2004 Nobel Prize in physiology or medicine.

Stem cells and drug design

Victorian College of Pharmacy researchers hope stem cells will help them better understand the action of existing drugs and aid in the discovery of new drugs for illnesses such as depression, obesity and anxiety.

Researchers discover new mechanism responsible for blood vessel tumors that cause facial deformities

Researchers have discovered a new mechanism responsible for the growth of blood vessel tumors that can cause facial deformities in infants and young children, paving the way for an antibody-based treatment to remove cells that fuel the tumors’ growth.

5 Oct 2004

Portion of the brain devoted to vision may play a prominent role in processing the spoken word in blind people

The findings yield important information about the brain's ability to compensate for lost function. The study appears in the October 3, 2004 online issue of Nature Neuroscience1 and in the journal's November issue.

Researchers pinpoint genetic cause of Timothy syndrome

Howard Hughes Medical Institute researchers have pinpointed the genetic cause of a devastating but rare childhood disorder, called Timothy syndrome, which underlies a form of severe cardiac arrhythmia.

Stress hormones lower threshold for aggression and aggression raises stress hormones

Scientists may be learning why it’s so hard to stop the cycle of violence. The answer may lie in the nervous system.

Scientists embark on a five-year study of the effects of soy isoflavones found in dietary supplements on various body tissues

A multidisciplinary team of scientists at the University of Illinois at Urbana-Champaign is embarking on a comprehensive five-year study of the effects of soy isoflavones found in dietary supplements on various body tissues.

Researchers have integrated heart cells grown from human embryonic stem cells into a host heart

Researchers at the Technion-Israel Institute of Technology and Rambam Medical Center have demonstrated that heart cells grown from human embryonic stem cells can integrate into the host heart and help regulate its activity, becoming in effect a biological pacemaker.

High calcium intake and vigorous exercise is the key to optimal increases in bone density

Prepubescence is a critical time for building bone mass in children. Strong bones are important for obvious reasons in growth and development. It is widely accepted that calcium intake and physical activity are two ways one can positively impact bone density.

Arsenic could be toxic at much lower levels than previously thought

Arsenic could be toxic at much lower levels than previously thought, suggesting that the new EPA drinking water standard of 10 parts per billion might still be too high, according to a team of researchers at Dartmouth Medical School.

Edible vaccine for HIV AIDS

Scientists from Novosibirsk are engaged in the development of an unusual vaccine which, apart from being less expensive to produce, safe and painless to administer, is also edible.
