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.
According to lead researcher in the field of ecotoxicology, human medicines that end up in the ecosystem are causing mutations in the male fish that mutate them into females. Professor Charles Tyler, fish physiologist and eco-toxicologist from Exeter University, has warned that more and more scientists should work on the exact impact of these drugs and chemicals on nature and marine animals.
A team of researchers led by Robert Wessells, Ph.D., assistant professor of physiology in the School of Medicine at Wayne State University, has received a two-year, $423,500 grant from the National Institute on Aging of the National Institutes of Health for the project, "Octopamine mediates benefits of endurance exercise in Drosophila."
A form of genetic variation, called differential RNA splicing, may have a role in tumor aggressiveness and drug resistance in African American men with prostate cancer.
Ondek, the Australian biotechnology company founded by Nobel Laureate Professor Barry Marshall, today announced it raised A$3.59 million in equity funding from professional and high-net-worth investors to support his work to develop a new treatment for childhood allergy.
Researchers have found that genetic variation may increase susceptibility of some astronauts to develop higher-than-normal carbon dioxide levels in the blood, which may contribute to eye abnormalities, including grooved bands on the retina in the eye and swelling of the optic nerve.
Although the basic outlines of human hearing have been known for years – sensory cells in the inner ear turn sound waves into the electrical signals that the brain understands as sound – the molecular details have remained elusive.
In 2015, there were nearly 10,000 teenage pregnancies in North Carolina. "Teen parents are less likely to finish high school, less likely to be well employed, and less likely to be in committed and stable relationships," said Rick Brown, Youth Education Program Director at Children's Home Society of North Carolina.
Elastin and collagen serve as the body's building blocks. They provide tensile strength and elasticity for a number of organs, muscles and tissues. Any genetic mutation short-circuiting their function can have a devastating, and often lethal, health impact.
Unfortunately, studies show that only about 5 million people living with OAB seek care from a doctor, and only half of those patients seek a specialist like a urologist or urogynecologist for treatment. It’s time to see a doctor if you’re using multiple leakage pads per day, not doing things you like because of the fear of leakage, planning all your travel around bathroom locations, or are worried about the problem every day.
A University of Delaware research team in the College of Health Sciences is combating chronic kidney disease (CKD) with exercise.
While the definitive causes remain unclear, several genetic and environmental factors increase the likelihood of autism spectrum disorder, or ASD, a group of conditions covering a "spectrum" of symptoms, skills and levels of disability.
Mounting scientific evidence shows that exercise is good not only for our bodies but for our brains. Yet, exactly why physical activity benefits the brain is not well understood.
Carbon nanotubes exhibit interesting characteristics rendering them particularly suited to the construction of special hybrid devices - consisting of biological issue and synthetic material - planned to re-establish connections between nerve cells, for instance at spinal level, lost on account of lesions or trauma.
Discovered more than two decades ago, the hormone leptin has been widely hailed as the key regulator of leanness. Yet, the pivotal experiments that probe the function of this protein and unravel the precise mechanism of its action as a guardian against obesity are largely missing.
Going for a walk outside, reading, listening to music - these and other enjoyable activities can reduce blood pressure for elderly caregivers of spouses with Alzheimer's disease, suggests a study in Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society. The journal is published by Wolters Kluwer.
Abbott announced today that the Alinity hq analyzer for hematology is now CE Marked and available in Europe and other countries that recognize CE Mark.
The mTOR pathway is probably the main pathway in humans and other animals that drives growth. That is, the accumulation of mass and adding mass to make an organism bigger by both making more cells, and making cells grow and become bigger.
UT Southwestern Medical Center scientists have identified a key protein that helps trigger ketamine's rapid antidepressant effects in the brain, a crucial step to developing alternative treatments to the controversial drug being dispensed in a growing number of clinics across the country.
Models of human disease are beneficial for medical research, but have limitations in predicting the way a drug will behave within the human body using data from non-human models because of inherent differences between species.
According to the National Onion Association (yes, that's a thing), approximately 170 countries grow onions, and it's estimated that 9.2 million acres of onions are harvested annually around the world.
