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.
This year, Medical Innovation will focus on healthcare on the front line. One of the highlights will be the British Army's Ice Maidens.
Increasing the amount of protein in the diet may reduce the liver's fat content and lower the risk of diabetes in people with nonalcoholic fatty liver disease.
A new study focusing on the environment inside cancer cells may lead to new targeted treatment strategies.
Tragic miscarriages for a couple have led to a discovery with potentially broad implications for future disease treatments, according to a team of researchers at the University of North Carolina School of Medicine. They identified a previously undiscovered gene mutation underlying hydrops fetalis – a fatal condition to fetuses due to fluid buildup in the space between organs.
The biggest hurdle to finding effective therapies for idiopathic pulmonary fibrosis (IPF) – a life-threatening condition in which the lungs become scarred and breathing is increasingly difficult – has been the inability to fully model the disease in animals, limiting the ability to observe and understand the disease.
Eating breakfast before exercise may "prime" the body to burn carbohydrates during exercise and more rapidly digest food after working out, University of Bath researchers have found.
Polyploidal cancer cells--cells that have more than two copies of each chromosome--are much larger than most other cancer cells, are resistant to chemotherapy and radiation treatments and are associated with disease relapse.
A new comprehensive natural history study about Amish nemaline myopathy in the Old Order Amish population focuses on the promise of gene therapy for this lethal disorder.
Higher levels of oxidative stress in males results in lower levels of cofactor BH needed to make the powerful blood vessel dilator nitric oxide.
Autophagy is a process of destruction and processing of damaged cell components by the cells themselves. It is used by a cell to clean itself of excessive organelles and sometimes for self-execution. This adaptive mechanism supports a healthy phenotype on the cellular level.
Ketogenic diet is a form of diet that consists of high fat and protein content and very low carbohydrate content. It has been known to promote weight loss and is considered to healthy. It has been adopted by many people globally.
Estrogen may protect against heart failure-related depression by preventing the production of inflammation-causing chemicals in the brain. The study is published ahead of print in the American Journal of Physiology-; Heart and Circulatory Physiology.
Scientists in Japan have found a potential marker to identify which people with abnormally fast heartbeats are at high risk of developing heart failure.
New research published in The Journal of Physiology indicates that ketogenic diets, which are low carbohydrate high fat eating plans that are known to lead to weight loss, may cause an increased risk of Type 2 diabetes in the early stage of the diet.
Osteoporosis, decreased physical activity and weight gain are serious health concerns for postmenopausal women.
Doxorubicin is a chemotherapy drug widely used in ovarian, bladder, lung, thyroid and stomach cancers, but it carries a harmful side effect. The drug causes a dose-dependent heart toxicity that can lead to congestive heart failure.
A biochemistry instructor curious about an enzyme discovered in the damaged neurons of people with multiple sclerosis made a leap toward a potential cure for countless neurodegenerative ills.
Light therapy is used to treat sleep disorders, depression, and seasonal mental disorders. In order to study its effects on the cardiovascular system and to make phototherapy safer for patients suffering from hypertension, experts from RUDN University were carrying out experiments on rats for five months.
Wearable devices are increasingly bought to track and measure health and sports performance: from the number of steps walked each day to a person's metabolic efficiency, from the quality of brain function to the quantity of oxygen inhaled while asleep.
A high-fat diet may promote the growth of pancreatic cancer independent of obesity because of the interaction between dietary fat and cholecystokinin, a digestive hormone.
