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.
Using new high-resolution imaging techniques, MDC researchers and colleagues have tracked titin, the body's largest protein, in real time throughout its entire lifecycle. The method and results could provide new insight into muscle development as well as treating damaged muscles and heart disease.
Weight loss mandates healthy eating and control of impulses when it comes to eating fat rich and processed foods. The actual story is quite different, as most persons on a diet have found out the hard way. The smell of food and even thoughts have given rise to binge eating, indulging in excessive food intake that has led to obesity and weight gain.
A review of more than 130 studies explains how sleep helps people learn new information and plays an important role in storing learned content for future use. The review is published in the January 2020 issue of Physiology.
High blood pressure in the lungs, known as pulmonary arterial hypertension (PAH), is a potentially fatal disease caused by obstruction of blood flow in the lungs.
You're on a diet, but the aroma of popcorn in the movie theater lobby triggers a seemingly irresistible craving.
As technology advances in the things we use every day, it's generally accepted they also become safer. But according to one UBC engineer, that may not be true for a large portion of the population.
SleepCogni has announced it will trial its unique insomnia treatment, following a £575k interim fund raising round, which includes existing shareholders and a new Innovate UK biomedical catalyst award, bringing its total funding to £1.7m to date.
Normally, bird flu viruses do not spread easily from person to person. But if this does happen, it could trigger a pandemic. Researchers from the MDC and RKI have now explained in the journal Nature Communications what makes the leap from animals to humans less likely.
A study by researchers in the United States and India has shown that probiotic yeasts derived from food are able to reduce the virulence of, and even prevent infections by, several types of fungi that are responsible for life-threatening infections in hospitalized and immune-compromised individuals, including the multi-drug resistant Candida auris, which was recently listed as an urgent threat by the U.S. Centers for Disease Control in its 2019 Antibiotic Resistance Threats report.
The role of adenosine in neurodegeneration and neuroregeneration has led to growing attention on adenosine receptors as potential drug targets in a range of brain disorders, including neuroregenerative therapy and treatment for amyotrophyic lateral sclerosis.
Biologists at Texas A&M University are making strides in understanding biological clock function in several model organisms and translating these studies into broader implications for human health.
Changes in heart rate due to low oxygen conditions experienced by the fetus during pregnancy could predict the future heart health of babies, suggests research published today in The Journal of Physiology.
While beauty may be in the eyes of the beholder, breathing is an agreed-upon necessity. A new study reveals how an emerging technique in rhinoplasty does more than improve physical appearance.
New research in mice suggests that exposure to antibiotics before birth may impair lung development in premature infants. The study, the first to explore the gut-lung axis in prematurity, is published ahead of print in the American Journal of Physiology—Lung Cellular and Molecular Physiology and was chosen as an APSselect article for December.
Members of a polar research expedition have provided researchers from Charité - Universitätsmedizin Berlin and the Max Planck Institute for Human Development with an opportunity to study the effects of social isolation and extreme environmental conditions on the human brain. The researchers found changes to the dentate gyrus, an area of the hippocampus responsible for spatial thinking and memory.
The dentate gyrus is the "input point" for the hippocampus part of the brain. It transmits information from the short term memory to the long term. It consists of granule cells, which are especially dense in this area of the brain, and interneurons, which are linked up in the central or peripheral nervous system between several nerve cells and have an inhibiting effect on their activity. Both types of cell process information and differentiate closely-related memories.
A new technology to unblock and remove secretions from the respiratory tract of children has been developed as part of a collaboration between researchers at Ben-Gurion University of the Negev and its affiliated Soroka University Medical Center, Cincinnati Children's Hospital Medical Center, and the University of Cincinnati.
Researchers have further analyzed a known signaling pathway they believe brings them one step closer to understanding the complex physiology of patients with chronic kidney disease (CKD), which might provide a path to new treatment options.
While some diets load up on protein and other diets dictate protein sources, it can be hard to know what to consume while managing weight or during weight loss.
University of Delaware researchers have some good news and some bad news that could help you in those critical, decisive moments.
