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.
New research is shedding light on why estrogenic hormones produce unintended results in women, giving hope to the idea that new drugs might reach their targets and work more effectively. Ultimately it could mean that postmenopausal women would know that hormone-replacement therapy would have only its intended result.
A behavioral neuroscientist at the University at Buffalo holds that the ingestion of afterbirth by a mother, a feature of pregnancy in nearly all non-human mammals, not only relieves postpartum pain, but optimizes the onset of maternal behavior by mediating the activity of specific opioid activity circuits in the brain.
The first evidence of cardiac progenitor cells – rare, specialized stem cells located in the newborn heart of rats, mice and humans – has been shown by researchers at the University of California, San Diego (UCSD) School of Medicine. The cells are capable of differentiation into fully mature heart tissue.
Underscoring the value of good prenatal care, new research suggests that early infection may create a cognitive vulnerability that appears later during stress on the immune system.
Now that even baseball players may need to seek new, more natural performance aids, will Japanese green tea sets become standard in dugouts and athletic training tables around the world?
Puberty, that awkward phase when boys and girls are primed for their sexual reproductive years as men and women, appears to be triggered by the brain's own version of "It takes two to tango," whereby a signal literally gets turned on by a molecule that is produced by a gene aptly named KiSS-1.
Researchers at UT Southwestern Medical Center have discovered that drugs commonly used to treat psychiatric illnesses and blood disorders in humans may protect the brain cells that die in people with Huntington's disease, possibly delaying the onset and slowing the progression of the disease.
Virginia Commonwealth University researchers have shown that a widely used drug for treating erectile dysfunction, Viagra, reduces the death of heart cells under heart attack-like conditions in a laboratory model.
Research published in the current issue of Science magazine reinforces the belief that aerobic capacity is an important determinant in the continuum between health and disease.
For decades, hormone replacement therapy (HRT) was prescribed for postmenopausal women to protect them from cardiovascular disease (CVD). However, results from the Women’s Health Initiative questioned its effectiveness, which has led to more caution in prescribing and using HRT for this purpose.
One of the most basic yet least understood processes in our bodies is how cells crawl along tissues. This behavior is essential to the formation of an embryo and other processes, but it must be tightly controlled. A disturbance can lead to the spread of cancer cells or diseases like Spina bifida and Lissencephaly, in which cells fail to reach their proper destinations.
A common protein that protects plants from fungal infection mimics the activity of a hormone in mammals that is linked to weight loss and is believed to play a role in mitigating heart disease, obesity and diabetes, according to a team of researchers at Purdue University and several collaborating institutions.
Melbourne researchers have found that over-eating at a very young age can have a long-lasting effect on the body and in particular seems to enhance the production of hormones made in fat and involved in metabolism.
A portable device similar to a home pregnancy test that can quickly detect the presence of infectious diseases, including HIV-AIDS and measles as well as biological agents such as Ricin and anthrax, is the goal of a new joint research project
Lifting weights can improve muscle strength and quality of life for people afflicted with the degenerative disease multiple sclerosis, a new University of Florida study finds.
Researchers at the University of California, San Diego (UCSD) School of Medicine have discovered the molecular sequence of events in mice that turn a juvenile heart into an adult heart capable of responding to increased workloads.
How do you remember your own name? Is it possible ever to forget it? The memory trace, or engram, "feels" like it is stored permanently in the brain and it will never be forgotten.
A multidisciplinary research centre at the University of Oxford will examine all types of beliefs, from those that make children think their stockings are filled by Santa Claus to the faith that drives fundamentalist terrorism.
A portable device similar to today's home pregnancy tests that can quickly detect the presence of infectious diseases, including HIV-AIDS and measles, as well as biological agents such as ricin and anthrax, is the object of a new joint university/industry research project.
InterMune, Inc. today announced that CHEST, the journal of the American College of Chest Physicians, published an important analysis of variables that measure clinical outcomes in patients with idiopathic pulmonary fibrosis (IPF), a deadly and debilitating lung disease.
