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.
It isn't uncommon for people to pass for ages much older or younger than their years, but researchers have now found that this feature doesn't apply to our brains. The findings reported online on August 16 in Current Biology, a Cell Press publication, show that sophisticated brain scans can be used to accurately predict age, give or take a year.
Rhomboid enzymes live in the cell’s membrane where their job is to cut the anchors of proteins, which releases the target proteins from the membrane.
Two researchers at Weill Cornell Medical College have deciphered a mouse's retina's neural code and coupled this information to a novel prosthetic device to restore sight to blind mice.
Patients implanted with continuous-flow left ventricular assist devices have low pulse pressure levels but are nevertheless able to maintain cardiovascular control through baroreflexes, German and US scientists have discovered.
University of Delaware professor Xinqiao Jia is part of a research team breaking new ground in the creation of artificial salivary glands.
A team of investigators from UC Davis and Peking University have discovered a mechanism that may explain how alpha hydroxyl acids (AHAs) -- the key ingredient in cosmetic chemical peels and wrinkle-reducing creams -- work to enhance skin appearance. An understanding of the underlying process may lead to better cosmetic formulations as well as have medical applications.
Centric Research Institute today launched CIRCUMserum, the first personal care product formulated specifically for use by circumcised men. CIRCUMserum is a daily moisturizing cream made from a patent-pending blend of essential botanical oils designed to condition areas of the penis dulled by the constant exposure resulting from circumcision.
New research, led by academics at the University of Bristol and published in the journal Pain, has identified the subtypes of sensory nerve cells that are likely to contribute to long-term nerve pain from partial nerve injury. It is hoped this will aid in development of more effective pain killers.
Adolescence is an important time not only for growing but for acquiring healthy habits that will last a lifetime, such as choosing foods rich in vitamins and minerals, and adopting a regular exercise regimen. Unfortunately, several studies have shown that adolescents' intake of important nutrients, as well as their performance on standard physical fitness tests, has fallen in recent years.
A fine-tuned combination of two existing pharmaceutical drugs has shown promise as a potential new therapy for people addicted to cocaine—a therapy that would reduce their craving for the drug and blunt their symptoms of withdrawal.
Women who experience vulvodynia are more likely than those without the pain syndrome to have fibromyalgia, interstitial cystitis, and irritable bowel syndrome, research suggests.
New research confirms no significant difference in the rates of death among patients with rheumatoid arthritis (RA) who were exposed to one of several TNF inhibitors used to treat RA, adalimumab (Humira), etanercept (Enbrel), and infliximab (Remicade).
The biomarkers desmosines and C-reactive protein could be used to assess disease severity in chronic obstructive pulmonary disease, show the results of a Swedish study.
Leslie Henderson is concerned about steroid abuse, not necessarily by sports luminaries like Barry Bonds and Mark McGwire, but rather by adolescents.
Adverse drug effects are harms caused by the use of a medication. There are many different types of ADEs, including medication errors.
Montefiore Medical Center has launched the nation's first fellowship program in Women's Physical Medicine and Rehabilitation (WPM&R), and established a new clinical program in this specialty.
A Purdue University student's research project related to zebrafish eye development could lead to a better understanding of vision problems that affect billions of people worldwide.
Researchers at Washington University School of Medicine in St. Louis have identified a potential target for treating diabetes and obesity.
There is growing evidence that, beyond what was previously believed, the adult human brain is remarkably malleable and capable of new feats -- even in the last decades of life.
Scientists have known for some time that throwing off the body's circadian rhythm can negatively affect body chemistry. In fact, workers whose sleep-wake cycles are disrupted by night shifts are more susceptible to chronic inflammatory diseases such as diabetes, obesity and cancer.
