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.
With over 20% of the population in industrial countries engaging shift work - in sectors such as healthcare and transportation - we urgently need to understand its health burden.
Human bodies have some built-in systems to care for themselves. The cells that line our lungs, nose, brain and reproductive system have cilia, which are tiny, hair-like structures designed to sweep out fluids, cells and microbes to stay healthy.
A research team led by biophysical chemist Professor Edward Lemke has engineered a designer organelle in a living mammalian cell in a new complex biological translation process. The created membraneless organelle can build proteins from natural and synthetic amino acids carrying new functionalities.
Leading physiology and pharmacology researchers will speak in a four-part series centered on the gut microbiome--the microbe population living in the digestive tract--and its role in wound recovery, hypertension and nervous system function.
Michigan State University has landed a $1.8 million National Institutes for Health R01 grant to improve brain implants - "electroceuticals" used to treat Alzheimer's, Parkinson's, depression and traumatic injuries.
Research efforts to comprehensively map adult human cells are in progress. But in a Perspective publishing March 28 in the journal Developmental Cell, researchers argue that there is a need to map children’s cells with the same level of granularity.
Fetal exposure to tobacco smoke in utero is associated with sudden infant death syndrome (SIDS) and cardiac arrhythmias in newborns. In a novel study in rabbits, investigators provide the first evidence linking fetal exposure to nicotine to long-term alterations of the cardiac sodium current.
Most people who weather an infection with influenza fully recover after a week or two. But for some, a severe case of the flu can actually reshape the architecture of their lungs and forever compromise their respiratory function.
The ERC Advanced Grant is one of the most prestigious funding programmes for research in Europe. Per-Olof Berggren, professor of experimental endocrinology at Karolinska Institutet, is now awarded this grant for the second time.
Scientists have mapped out how the body transports testosterone, and their surprising findings may explain low testosterone levels seen in men with diabetes or patients on certain medications.
They are the scavengers of the deep and the dead. Hagfish are slimy bottom-dwellers that live off the carcasses of dead sea creatures and thrive in deep waters where oxygen is hard to come by. In fact, their hearts can keep on beating for 36 hours without any oxygen, making hagfish a champion among anoxia-tolerant fish.
The often embraced 'cheat day' is a common theme in many diets and the popular ketogenic diet is no exception. But new research from UBC's Okanagan campus says that just one 75-gram dose of glucose--the equivalent a large bottle of soda or a plate of fries--while on a high fat, low carbohydrate diet can lead to damaged blood vessels.
The portion of the brain known as the hypothalamus is small but mighty -- it controls fundamental behaviors and physiology that are essential for survival.
A frontline chemotherapy drug given to patients with pancreatic cancer is made less effective because similar compounds released by tumor-associated immune cells block the drug's action, research led by the University of Michigan Rogel Cancer Center found.
Research has found that many cases of diabetes are missed when the hemoglobin A1c blood test is used solely to diagnose the disease.
A synthetic peptide appears to directly disrupt the destructive inflammation that occurs in nephritis, enabling the kidneys to better recover and maintain their important functions, investigators report.
A diet high in fats and sugars is known for its unhealthy effects on the heart. Scientists now have found that a high-fat, high-sugar diet in mouse mothers before and during pregnancy causes problems in the hearts of their offspring, and that such problems are passed down at least three generations, even if the younger generations only eat a standard mouse chow diet.
A new article explores the pathophysiological factors that link sleep disturbances and Alzheimer's disease.
An international research team from the George Washington University, U.S., and the Moscow Institute of Physics and Technology, Russia, has developed an open-source solution for multiparametric optical mapping of the heart's electrical activity.
Scientists at the University of Cambridge have suggested that subtle changes to the drugs administered to mothers threatened with preterm birth or to premature babies could further improve clinical treatment and help increase their safety.
