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 MRI study shows heart ages differently in men and women

A federally funded analysis of MRI scans of the aging hearts of nearly 3,000 adults shows significant differences in the way male and female hearts change over time.

New genetic discovery could lead to better treatment for X-linked diseases

Think back to middle school biology class, when you learned that boys have an X and a Y chromosome inside each cell, and girls have two X's.

Breakthrough advancements on new molecular mechanism may lead to Parkinson's treatments

More than one million people in the United States are afflicted with Parkinson's disease, a progressive disorder of the brain that affects movement and coordination. The cause is typically unknown, and presently there is no cure for the disease.

Thyroid hormone treatment improves cardiac health in female rats with high blood pressure

Thyroid hormones administered to female rats with high blood pressure led to encouraging cardiac improvements, according to a study in the American Journal of Physiology led by NYIT College of Osteopathic Medicine researcher Martin Gerdes.

New tool may help identify high risk atherosclerotic plaques

Researchers have developed and validated a new tool to help identify unstable or high risk atherosclerotic plaques--inflamed fatty deposits in the artery wall and a main contributor to cardiovascular disease (CVD). This breakthrough may lead to better identifying which plaques are considered at the highest risk for rupturing and causing a heart attack or stroke.

NC State scientists take a giant leap closer to understanding locomotion from the leg up

Using an "Avatar"-like bio-robotic motor system that integrates a real muscle and tendon along with a computer controlled nerve stimulator acting as the avatar's spinal cord, North Carolina State University researchers have taken a giant leap closer to understanding locomotion from the leg up.

Researchers explore how nitrate-rich beet juice may affect high altitude acclimatization

Ever since human beings first began climbing the world's tallest mountains, they have struggled with a basic problem: altitude sickness, caused by lower air pressures which affect the ability of our bodies to take up oxygen.

Scientists can now use skin samples from older patients to grow brain cells

For the first time, scientists can use skin samples from older patients to create brain cells without rolling back the youthfulness clock in the cells first. The new technique, which yields cells resembling those found in older people's brains, will be a boon to scientists studying age-related diseases like Alzheimer's and Parkinson's.

Brain & Behavior Research Foundation to honor nine scientists with Outstanding Achievement Prizes

The Brain & Behavior Research Foundation will honor nine scientists with its 2015 Outstanding Achievement Prizes for their work in schizophrenia, mood disorders, child and adolescent psychiatry, and cognitive neuroscience.

High levels of satiety hormone leptin contribute to cardiovascular disease in obese individuals

While high levels of the satiety hormone leptin don't help obese individuals lose weight, they do appear to directly contribute to their cardiovascular disease, researchers report.

Researchers explore how common genetic mutation influences effects of taking melatonin close to mealtime

Researchers from Brigham and Women's Hospital and the University of Murcia, Spain, have shed new light on why people who carry a common genetic mutation may be more at risk for developing type 2 diabetes. By carefully studying healthy subjects, researchers were able to chart the effect of melatonin supplements on blood sugar control.

Sexual activity causes physiological changes in the body that increase women's chances of getting pregnant

Research from Indiana University has found that sexual activity triggers physiological changes in the body that increase a woman's chances of getting pregnant, even outside the window of ovulation.

Targeting protein used by tumors to help detect food supplies could restrict cancerous cells' ability to grow

Oxford University researchers have identified a protein used by tumours to help them detect food supplies. Initial studies show that targeting the protein could restrict cancerous cells' ability to grow.

Insulin sensitivity of main glucose storage sites in the body improve following gastric bypass surgery

Roux-en-Y, the most common type of gastric bypass surgery, can lead to remission of type 2 diabetes along with weight loss. A new study in the American Journal of Physiology—Regulatory, Integrative and Comparative Physiology examines why, finding that insulin sensitivity of the main glucose (sugar) storage sites in the body improve after gastric bypass surgery.

Short bursts of high intensity exercise may improve cardiovascular health in teens

Adolescents who perform just eight to ten minutes of high-intensity interval exercise three times a week could be significantly reducing their risk of developing heart conditions, new research has concluded.

Unlocking the genes behind antibiotic resistance: an interview with Professor Romesberg

Bacteria are very, very diverse. This is why their susceptibility to different antibiotics can be very different. It also makes the tools they have to evolve resistance in many cases different.

Brain prosthesis may help individuals suffering from memory loss

Researchers at USC and Wake Forest Baptist Medical Center have developed a brain prosthesis that is designed to help individuals suffering from memory loss.

New study identifies inflammatory lung disease as risk factor for insulin resistance, diabetes

Numerous studies have identified obesity and poor diet as risk factors for insulin resistance and diabetes. A new study adds another risk factor to the list: inflammatory lung disease. Published in the American Journal of Physiology—Regulatory, Integrative and Comparative Physiology, the study reports that inflammation in the lungs is enough to induce the body-wide inflammation that can lead to insulin resistance.

Researchers find way to predict occurrence of some cardiac arrhythmias

Researchers have discovered how to predict some cardiac arrhythmias several steps before they even occur. It's a finding that could lead to an improved cardiac device, with equipment designed to detect when arrhythmias are about to occur and then act to prevent them.
