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.
The parathyroid glands - four small organs the size of grains of rice located at the back of the throat - glow with a natural fluorescence in the near infrared region of the spectrum.
Mitochondria, those battery-pack organelles that fuel the energy of almost every living cell, have an insatiable appetite for calcium. Whether in a dish or a living organism, the mitochondria of most organisms eagerly absorb this chemical compound.
Alnylam Pharmaceuticals, Inc., a leading RNAi therapeutics company, and collaborators at Massachusetts General Hospital (MGH), the Broad Institute, and the David H. Koch Institute for Integrative Cancer Research at the Massachusetts Institute of Technology (MIT), today announced new findings published in Nature.
Coaches, physiologists and athletes alike will attest to the importance of warming up before athletic competition. Warming up increases muscle temperature, accelerates oxygen uptake kinetics and increases anaerobic metabolism, all of which enhance performance.
Michael F. Holick, PhD, MD, director of the General Clinical Research Center and professor of medicine, physiology and biophysics at Boston University School of Medicine, is this year's recipient of The Delbert A. Fisher Research Scholar Award from the Endocrine Society for his scholarly work on the history of endocrinology.
UT Southwestern Medical Center scientists are shedding new light on why the anesthetic drug ketamine produces a fast-acting antidepressant response in patients with treatment-resistant depression.
Scientists have developed a way to turn memories on and off-literally with the flip of a switch. Using an electronic system that duplicates the neural signals associated with memory, they managed to replicate the brain function in rats associated with long-term learned behavior, even when the rats had been drugged to forget.
New clinical guidelines developed by an expert panel that include 100 evidence-based recommendations for optimal care of patients with hyperthyroidism and other causes of thyrotoxicosis are presented in the current issue of Thyroid, a peer-reviewed journal published by Mary Ann Liebert, Inc.
Investigators at UCLA's Center for Neurobiology of Stress have been studying the links between the brain and digestive system in the development and treatment of common chronic digestive disorders in adults and children.
In the longest running U.S. study of premature infants who are now 23 years old, University of Rhode Island Professor of Nursing Mary C. Sullivan has found that premature infants are less healthy, have more social and school struggles and face a greater risk of heart-health problems in adulthood.
EndoSphere Inc., a medical technology company that holds 23 U.S. and international issued and pending patents, announced today that the U.S. Patent and Trademark Office has issued the company a patent covering the use of its endoscopically implantable devices for the treatment of metabolic diseases, including obesity and type 2 diabetes.
Over the past decade, much progress has been made regarding the understanding and promise of personalized medicine. Scientists are just beginning to consider the impact of gene-diet interactions in different populations in regards to disease prevention and treatment.
Actelion Pharmaceuticals US, Inc. and the ENTELLIGENCE Steering Committee recognized four young researchers and their mentors for their efforts in advancing research in PAH. Each researcher will receive a 12-month mentored grant of up to $100,000 in support, funded through the ENTELLIGENCE program supported by Actelion. The announcement was made at an awards luncheon, during which the recipients of the 2011 awards gave an overview of their proposed work.
A new study published by the American Physiological Society offers the strongest evidence yet that vulnerability to type 2 diabetes can begin in the womb, giving new insight into the mechanisms that underlie a potentially devastating disease at the center of a worldwide epidemic.
Driving new technologies that will help expand the availability of MRI scanners beyond the hospital to smaller clinic settings, GE Global Research, the technology development arm for the General Electric Company, and Mayo Clinic, have received a five-year, $5.7 million grant from the National Institute of Biomedical Imaging and Bioengineering (NIBIB), and the National Institute of Neurological Disorders and Stroke (NINDS), components of the National Institutes of Health.
Inspire Medical Systems, the leading developer of neurostimulation therapies for the treatment of obstructive sleep apnea (OSA), announced today The STAR trial, evaluating both the safety and effectiveness of Inspire Upper Airway Stimulation (UAS) therapy, is currently underway at 9 leading medical centers across the United States and at 4 sites in Europe.
Researchers have developed a new type of imaging technology to diagnose cardiovascular disease and other disorders by measuring ultrasound signals from molecules exposed to a fast-pulsing laser.
New research has shown that children's risk for learning and behavior problems and obesity rises in correlation to their level of trauma exposure, says the psychiatrist at the Stanford University School of Medicine and Lucile Packard Children's Hospital who oversaw the study.
New research has shown that children’s risk for learning and behavior problems and obesity rises in correlation to their level of trauma exposure, says the psychiatrist at the Stanford University School of Medicine and Lucile Packard Children’s Hospital who oversaw the study. The findings could encourage physicians to consider diagnosing post-traumatic stress disorder rather than attention deficit/hyperactivity disorder, which has similar symptoms to PTSD but very different treatment.
Profil Institute for Clinical Research, Inc., a company leading the industry in early phase clinical trials for diabetes and obesity, and Rosa & Co. LLC, a drug development advisory firm with expertise in drug-disease modeling and simulation, jointly announced today a strategic alliance to offer Profil Institute customers use of Rosa's modeling technology to simulate disease physiology, drug action, patient variability, and trial outcomes for their early phase clinical development programs.
