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.
Researchers aiming to understand why autism spectrum disorders (ASD) are more common in boys have discovered differences in a brain signaling pathway involved in reward learning and motivation that make male mice more vulnerable to an autism-causing genetic glitch.
My lab, broadly speaking, is interested in trying to understand interactions between cells and materials. Those could be materials that are present within living tissue or materials that we use for engineering purposes to try to do something of technological or therapeutic interest.
Scientists at Columbia's Zuckerman Institute today received a grant from the Chan Zuckerberg Initiative donor advised fund, an advised fund of the Silicon Valley Community Foundation, to construct an atlas of gene activity of all cells in the human spinal cord.
Treatments for high blood pressure do not totally reverse its damaging effects on the vascular rhythms that help circulation of the blood say researchers.
Seizure disorders -- including epilepsy -- are associated with pathological hyperexcitability in brain neurons. Unfortunately, there are limited available treatments that can prevent this hyperexcitability.
High cholesterol levels have been associated with breast cancer spreading to other sites in the body, but doctors and researchers don't know the cause for the link.
Doctors long have stressed the importance of good nutrition for expectant mothers. Now biologists at the University of Cincinnati say the father's diet could play a similar role in the health of a baby.
A pregnant mother sleeping on her back during late pregnancy may cause problems for the fetus, according to new research published in The Journal of Physiology. This is the first study to monitor unborn babies overnight and at the same time record the mother's position during sleep.
A study underway at the Institute for Exercise and Environmental Medicine is investigating the respiratory effects of obesity in children, including obese children who may be misdiagnosed with asthma.
When a drink at the local watering hole turns into five or six, what are the effects on our brains and hearts? How does too much to drink affect how we sleep? How does binge drinking affect blood pressure for people who drink socially but not usually to excess? Do women's bodies process alcohol differently depending on stages of their menstrual cycles?
Children with attention deficit hyperactive disorder (ADHD) are likely to also have trouble with touch (tactile) processing. A new study finds that children with ADHD fare worse on several tests of tactile functioning, including reaction time and detecting a weak stimulus on the skin (detection threshold).
Aging is characterized by increased levels of inflammatory markers in the bloodstream, a phenomenon that has been termed "inflammaging". This type of enhanced inflammation tone, also designated as low grade inflammation, is associated with age-related decline of many functional systems and with increased risk of sickness, poor well-being and mortality.
Functional magnetic resonance imaging, or fMRI, has transformed our view of the brain, allowing researchers to pinpoint areas associated with everything from depression and dementia to playing chess and engaging in sex.
Preeclampsia is the most dangerous form of hypertension during a pregnancy and can be fatal for both mother and child. Though it is known to originate in the placenta, the root causes remain largely a mystery.
A research team led by the Forsyth Institute today received a $5.4 million award from the National Institutes of Health to pursue revolutionary research of microbes living in the mouth and within the human body.
Brazilian researchers at the University of São Paulo's Bioscience Institute (IB-USP) are starting to unravel the molecular mechanisms by which the parasite that causes cutaneous leishmaniasis manages to circumvent the host organism's defenses and infect new cells.
Fetal alcohol spectrum disorders, which result from maternal alcohol use during pregnancy, is the most common preventable cause of neurodevelopmental disabilities and affects an estimated 2 percent to 5 percent of school-aged children in the United States, according to the U.S. Centers for Disease Control and Prevention.
UCLA biophysicists have developed a new method to rapidly determine a single cell's stiffness and size -- which could ultimately lead to improved treatments for cancer and other diseases.
The U.S. Department of Defense has awarded a team of scientists and physicians from leading health care institutions across Phoenix a $1.3 million grant over three years to study traumatic brain injury and its relationship to dementia.
RCSI is leading an international team of scientists on a major research study that aims to train the next generation of brain cancer researchers.
