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.
Obesity, already a global epidemic, is on the rise. Over one-third of the U.S. population is currently afflicted, according to the Centers for Disease Control and the monetary costs alone are approaching $150 billion dollars annually.
ERT, a global data and technology company that minimizes uncertainty and risk in clinical trials, today introduced an advanced respiratory clinical trial solution to centrally capture, measure and analyze Lung Clearance Index data, in near real-time, to assess lung performance with more precision than traditional spirometry measures.
Research looking at genomic data from women with a genetic risk for breast cancer, who may never develop cancer, found their cancer-free state may be related to a second genetic variation.
Disruptions in a protein folding process occurring in the brain, known as endoplasmic reticulum (ER) stress, may cause non-alcoholic fatty liver disease, independent of other factors. A research team at the George Washington University published their results in the Journal of Clinical Investigation Insight.
Researchers at the University of Michigan, Stanford University and biotech company ConfometRx have captured the first cryo-electron microscopy snapshots of a key cellular receptor in action.
Blood platelets shore up open wounds and help cuts heal, but they can also cause heart attacks and strokes when a congealed ball of platelets known as a thrombus breaks free from a site of injury and gets lodged in blood vessels that feed oxygen to the brain or heart.
A Yale research team has found that by tinkering with the surface properties of drug-loaded nanoparticles, they can potentially direct these particles to specific cells in the brain.
During this period, there was a revival of the Classical medicine of Ancient Greece and Rome, particularly the ideas of the Greek philosopher Hippocrates and the Roman physician Galen of Pergamon.
A new DNA vaccine when delivered to the skin prompts an immune response that produces antibodies to protect against toxic proteins associated with Alzheimer's disease – without triggering severe brain swelling that earlier antibody treatments caused in some patients.
The incidence of Alzheimer's disease (AD) is expected to triple in the coming decades and no cure has been found. Recently, interest in dietary approaches for prevention of cognitive decline has increased.
Athletes often have to compete late in the evening, when they are no longer able to perform at their best. As reported in the journal Frontiers in Physiology, however, researchers from the University of Basel have shown that athletes who are exposed to blue light before competing can significantly increase their performance in the final spurt.
The enzymes nitric oxide (NO) synthase (NOS1) and protein kinase C (PKC) play an important role in a variety of signal transfer processes in neurons of the brain, as well as in many cell types of other organs.
A new study suggests that fetal alcohol exposure reduces the taste system's responsiveness to the bitter flavor and burning sensation of many varieties of alcoholic beverages.
Royal Philips will showcase its market-leading image guided therapy solutions at EuroPCR 2017 (Paris, May 16 – 19, 2017) to advance interventional cardiology and make care more personalized, while optimizing patient care and hospital budgets. This year, the healthcare industry is celebrating the 40th anniversary of angioplasty, the minimally invasive treatment of obstructed blood vessels, and as a leader in interventional cardiology, Philips is reinforcing its longstanding commitment to transforming cardiac care with meaningful innovations.
A new study published this week in the Journal of Physiology finds that young veterans with combat-related post-traumatic stress disorder (PTSD) have an increased 'fight or flight' response during mental stress.
A team of University of Kentucky researchers has discovered that macrophages, a type of immune cell that clears debris at injury sites during normal wound healing and helps produce scar tissue, are required for complex tissue regeneration in mammals.
A grant totaling $2,668,127 over five years will fund studies of the complex processes involved in both healthy aging and Alzheimer's disease, in the laboratory of Jackson Laboratory (JAX) Assistant Professor Catherine Kaczorowski, Ph.D.
Young veterans with combat-related post-traumatic stress disorder (PTSD) have an increased 'fight or flight' response during mental stress, according to new findings published this week in the Journal of Physiology.
A new study shows that whole tomato extracts from two different Southern Italy cultivars inhibit gastric cancer cell growth and malignant features, paving the way for future studies aimed at implementing lifestyle habits not only for prevention but potentially as a support to conventional therapies.
Osteoarthritis can potentially be prevented with a good diet and regular exercise, a new expert review published in the Nature Reviews Rheumatology reports.
