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.
Gulf War veterans with unexplained illnesses that cause fatigue, headaches, respiratory disorders and memory problems can improve their balance with a device developed by Rutgers University researchers.
Washington State University researchers have seen cognitive changes in the offspring of rats exposed to heavy amounts of cannabis. Their work is one of the rare studies to look at the effects of cannabis during pregnancy.
Serotonin receptors are common drug targets in the treatment of pain, gastrointestinal dysfunctions, and mood disorders yet little is known about their three-dimensional structure.
Researchers at the University of Zurich and Harvard University have developed a new strategy in the search for psychoactive drugs.
All mammalian cells need a ready supply of calcium ions to execute functions as diverse as neurotransmission, muscle contraction, hormone release, or immune responses. So fundamental is this requirement that cells protect themselves from disaster by storing calcium in a network of intracellular cisterns called the endoplasmic reticulum, or ER.
The University of Missouri has received $7.229 million for continued operation of the National Swine Resource and Research Center.
Each year, at least 3 million people worldwide die of sudden cardiac death. In the U.S., this number reaches up to 450,000 people.
Researchers have developed a three-dimensional 'organ on a chip' which enables real-time continuous monitoring of cells, and could be used to develop new treatments for disease while reducing the number of animals used in research.
A study conducted by LSU Health New Orleans researchers provides new evidence that early exposure to multiple health disciplines in pipeline programs targeting underserved/underrepresented students interested in health professions reduces the development of traditional role and leadership stereotypes about professional health care teams and practice.
By incorporating a gene-suppressing drug into an over-the-counter gel, researchers at Albert Einstein College of Medicine and their colleagues cut healing time by half and significantly improved healing outcomes compared to control treatments.
Ivermectin is six times more toxic than Moxidectin for insects in charge of the recycling of organic matter. For the first time ever, there is scientific evidence based on physiological studies and this should be taken into account when using antiparasitic agents for livestock.
More than 60 million people in the U.S. suffer from disorders in the gastrointestinal tract that could be cured by electrical stimulation, but scientists don't fully understand the therapy's effects on a critical organ: the stomach.
Scientists trying to identify the roots of sudden infant death syndrome, the leading cause of death in U.S. infants between 1 month and 1 year old, have increasingly turned their attention to the neurotransmitter serotonin and the brain cells that produce it.
UT Southwestern scientists, working with colleagues at a sister institution in Houston, have identified a new target for battling a deadly form of leukemia.
New research from York University on fat tissue is providing an important clue as to how females stay healthier than males, even as their body fat increases.
A major grant to fund curiosity-driven research into plant communication has been awarded to a John Innes Centre researcher and colleagues from two European institutes.
Postdoctoral Researcher Tetsuya Kotani, Associate Professor Hitoshi Nakatogawa, Honorary Professor Yoshinori Ohsumi and colleagues at Tokyo Institute of Technology have analyzed the Atg protein Atg2, whose function had been completely unknown, and have discovered that Atg2 tethers the pre-autophagosomal membrane to the endoplasmic reticulum during autophagosome formation.
The biological differences between women and men go beyond basic anatomy. Researchers must consider sex differences down to the cellular level in order to discover crucial information about the varied development, function, and biology between women and men.
When alcohol enters the brain, it causes neurons in a specialized region called the ventral tegmental area, or VTA -- also known as the "pleasure center" -- to release dopamine, a neurotransmitter that produces those feel-good sensations, and tells the brain that whatever it just experienced is worth getting more of.
With a pair of RO1 grants from the National Institutes of Health, pain researcher Daniela Salvemini, Ph.D., will embark on two new research projects, studying chemotherapy-induced cognitive impairment, or "chemo brain," symptoms and unwanted side effects of opioids.
