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.
A novel approach to treating children diagnosed with autism spectrum disorder could help them navigate their world by teaching them to turn their symptoms into strengths.
AATS and three cardiovascular professional societies today released an overview of transcatheter therapies for mitral regurgitation.
Stanford University School of Medicine neuroscientists have discovered a new role played by a common but mysterious class of brain cells.
Five teams of scientists earned research seed grants awarded this year by the John S. Dunn Foundation. The awards support new collaborations by researchers at Rice University's BioScience Research Collaborative (BRC) and their partners at other institutional members of the Gulf Coast Consortia (GCC).
Measurement of heart rate variability (HRV) is a useful method when assessing the role of the nervous system for heart function. Standard reference values for heart rate variability in adults have existed for a long time already, but similar values have not been available for children until now.
Rats whose mothers were fed a high-fat diet during pregnancy and nursing were able to stave off some of the detrimental health effects of obesity by exercising during their adolescence, new Johns Hopkins research shows.
Sorin Group, a global medical company and a leader in the treatment of cardiovascular diseases, announced today that it has received CE Mark approval for the Solo Smart stentless aortic valve.
A single overactive enzyme worsens the two core defects of diabetes—impaired insulin sensitivity and overproduction of glucose—suggesting that a drug targeting the enzyme could help correct both at once, according to mouse studies done by researchers at Columbia University Medical Center. The findings were published today in the online edition of Cell Metabolism.
Biologists at Brown University have found a way to measure the effects of aging by watching the ebb and flow of chromatin, a structure along strands of DNA that either silences or permits gene expression. In several newly published experiments they show that gene silencing via chromatin in fruit flies declines with age.
While young children sleep, connections between the left and the right hemispheres of their brain strengthen, which may help brain functions mature, according to a new study by the University of Colorado Boulder.
The uncoupling Protein 1 (UCP1) is found exclusively in brown adipose tissue. Until some years ago it was thought that only babies and hibernating animals had brown adipose tissue, but since then it also has been found in adults, so UCP1 could be useful in the fight against obesity.
Diseases affecting the kidneys represent a major and unsolved health issue worldwide. The kidneys rarely recover function once they are damaged by disease, highlighting the urgent need for better knowledge of kidney development and physiology.
Columbia University Medical Center has honored Philipp E. Scherer, PhD, with the 15th Naomi Berrie Award for Outstanding Research in Diabetes, for his work that helped usher in a new understanding of fat and its role in diabetes and other metabolic diseases. His discovery of adiponectin, a hormone produced by fat, helped transform the scientific concept of fat as an inert storage depot to one of it as an endocrine "organ" that exerts control over the brain, muscles, and other organs. The award, given annually by CUMC's Naomi Berrie Diabetes Center, is Columbia's top honor for excellence in diabetes research.
Human noses come in all shapes and sizes. But one feature seems to hold true: Men's noses are bigger than women's.
Prior research has shown not getting enough sleep can impact your weight, but new BYU research finds the consistency of your bed time and wake time can also influence body fat.
Findings from a 15-year study published in Acta Obstetricia et Gynecologica Scandinavica, a journal of the Nordic Federation of Societies of Obstetrics and Gynecology, indicate that human error is the most common cause of infant asphyxiation at birth. Inadequate fetal monitoring, lack of clinical skills, and failure to obtain senior medical staff assistance are most often cited in Norwegian compensation claims following birth asphyxia.
A research team at Worcester Polytechnic Institute and The Rockefeller University in New York has developed a novel system to image brain activity in multiple awake and unconstrained worms. The technology, which makes it possible to study the genetics and neural circuitry associated with animal behavior, can also be used as a high-throughput screening tool for drug development targeting autism, anxiety, depression, schizophrenia, and other brain disorders.
Diseases affecting the kidneys represent a major and unsolved health issue worldwide. The kidneys rarely recover function once they are damaged by disease, highlighting the urgent need for better knowledge of kidney development and physiology.
As science continues to support the role of protein in building and maintaining lean muscle, maintaining weight and aging healthy, consumers are embracing the important role of protein in the diet. But not all proteins are created equal and it turns out that protein quality really does matter.
A £1.1 million grant to understand how one of the brain's key neurotransmitters called 'acetylcholine' influences brain activity has been awarded to University of Bristol researchers. The Wellcome Trust award will help scientists understand more precisely how the release of acetylcholine is changing brain cell activity to influence memory and cognition.
