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.
The Alzheimer's Biomarkers Consortium - Down Syndrome, a multi-institution research team, co-led by members from the University of California, Irvine, has been awarded an unprecedented five-year, $109 million grant by the National Institutes of Health, to expand research on the biomarkers of Alzheimer's disease in adults with Down syndrome.
A team of medics from RUDN University conducted an experiment on rats and confirmed that surgeries in the nasal cavity can cause behavioral changes, namely, make the animals timider.
Brain cell dysfunction in low oxygen is, surprisingly, caused by the very same responder system that is intended to be protective, according to a new published study by a team of researchers at the Case Western Reserve University School of Medicine.
As researchers and medical professionals work to develop new treatments for cancer, they face a variety of challenges.
A low dose of ketamine, administered intravenously, does not alter a healthy human's tolerance to blood loss. In other words, if someone was given ketamine to kill pain associated with a battlefield injury, they would be able to tolerate blood loss just as well as someone who did not received this pain killer.
You've heard that they can sag with age, perpetuate the name of a regrettable ex, or reveal an embarrassing inability to spell. But tattoos may also impair the way we sweat, potentially causing the body to overheat if the tattoos cover a large area of the body.
Researchers at McMaster University have found distinct effects of adversity early in life in the genomes of men compared to women who were born extremely preterm.
With a little tweak of the color palette, University of Virginia School of Medicine researchers have made it easier for scientists to understand biological processes, track happenings inside individual cells, unravel the mysteries of disease and develop new treatments.
Researchers at Mount Sinai have proposed a groundbreaking new way to study the interaction between complex biological systems in the body and the environment.
A breakthrough study, led by researchers from the University of California, Irvine, results in the restoration of retinal and visual functions of mice models suffering from inherited retinal disease.
Personalized treatment options for patients with lung cancer have come a long way in the past two decades.
A new Alzheimer's study found that impaired blood flow in the brain is correlated with the buildup of tau tangles, a hallmark indicator of cognitive decline.
Sepsis is estimated to cause 11 million deaths every year in the world. Its treatment is based on the use of antibiotics and organ support measures, but many times it fails due to unsuccessful attempts at modulating the immune response.
In humans, large arteries lose elasticity and thicken with age and other pathological conditions, leading to arteriosclerosis and high blood pressure.
The National Institutes of Health has awarded a team of researchers, led by the University of California, Irvine's Xiangmin Xu, PhD, a five-year, $3 million grant for a project titled, "Single-Cell Analysis of Aging-Associated 4D Nucleome in the Human Hippocampus."
Regular cannabis exposure in rats during pregnancy may cause their offspring to have long-term cognitive deficiencies, asocial behavior, and anxiety later in adulthood.
Scientists from Russia and Switzerland have probed into nanostructures covering the corneas of the eyes of small fruit flies. Investigating them the team learned how to produce the safe biodegradable nanocoating with antimicrobial, anti-reflective, and self-cleaning properties in a cost-effective and eco-friendly way.
In first-of-their-kind observations in the human brain, an international team of researchers has revealed two well-known neurochemicals -; dopamine and serotonin -; are at work at sub-second speeds to shape how people perceive the world and take action based on their perception.
Scientists at Wake Forest School of Medicine have recorded real time changes in dopamine and serotonin levels in the human brain that are involved with perception and decision-making.
With a nearly $2.6 million grant from the National Institutes of Health, Michigan State University researchers are using nanoscopic particles to turn the body's own cells into weapons that cancer won't see coming.
