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.
Abbott announced today that the Alinity hq analyzer for hematology is now CE Marked and available in Europe and other countries that recognize CE Mark.
The mTOR pathway is probably the main pathway in humans and other animals that drives growth. That is, the accumulation of mass and adding mass to make an organism bigger by both making more cells, and making cells grow and become bigger.
UT Southwestern Medical Center scientists have identified a key protein that helps trigger ketamine's rapid antidepressant effects in the brain, a crucial step to developing alternative treatments to the controversial drug being dispensed in a growing number of clinics across the country.
Models of human disease are beneficial for medical research, but have limitations in predicting the way a drug will behave within the human body using data from non-human models because of inherent differences between species.
According to the National Onion Association (yes, that's a thing), approximately 170 countries grow onions, and it's estimated that 9.2 million acres of onions are harvested annually around the world.
Highly active older adults experience no limitations in the lungs' capacity to exchange gases (lung-diffusing capacity) during physical activity, researchers have found. The study is published in the Journal of Applied Physiology.
According to a new study, concentrated broccoli sprout extract may help type 2 diabetes patients manage their blood sugar.
One area of research within mechanobiology, the study of how physical forces influence biological processes, is on the interplay between cells and their environment and how it impacts their ability to grow and spread.
It was long thought that gastric ulcers and other digestive woes were brought about by stress. But in 2005, clinical fellow Barry J. Marshall and pathologist J. Robin Warren were awarded the Nobel Prize in Physiology or Medicine for recognizing the role of Helicobacter pylori in gastritis and peptic ulcer disease.
Saint Louis University researchers report in Molecular Metabolism new findings that the nuclear receptor REV-ERB appears to play a key role in muscle regeneration, suggesting the receptor may be a good target for new drugs to treat a variety of muscle disorders and injuries.
As the obesity epidemic continues, new data shed light on which nutrients and what quantity of those nutrients promote health or disease.
How difficult is it to conceive? According to a widely-held view, fewer than one in three embryos make it to term, but a new study from a researcher at the University of Cambridge suggests that human embryos are not as susceptible to dying in the first weeks after fertilization as often claimed.
Organoids are bits of tissue grown in vitro, in a near-physiological 3D setting. The particularity consists in the fact that organoids retain features of the patient they are derived from, even when cultured outside of the human body. This is very different from what traditional, conventional cell culture has been able to do over the past 50 years or so.
In a new review of the effects of acute exercise published in Brain Plasticity, researchers not only summarize the behavioral and cognitive effects of a single bout of exercise, but also summarize data from a large number of neurophysiological and neurochemical studies in both humans and animals showing the wide range of brain changes that result from a single session of physical exercise.
The risk of developing type 2 diabetes (T2D) by age 20 was 12 times as high in severely obese American Indian children 5 to 9 years of age as in normal-weight youth in that age range, according to a study titled "Long-term Risk of Type 2 Diabetes in Youth with Increasing Severity of Obesity," presented today at the American Diabetes Association's 77th Scientific Sessions at the San Diego Convention Center.
Researchers from the University of Copenhagen, together with colleagues from the University of Colorado, Tufts University, Centro de Investigación Biomédica en Red de Fisiopatología de la Obesidad y Nutrición and Gelesis, Inc., presented new data demonstrating that blood sugar (glucose) and/or fasting insulin should be used to select the right diet, particularly for people with prediabetes and diabetes
In a paper published in the journal Pain, Saint Louis University researcher Daniela Salvemini, Ph.D., reports discovering a key molecular pathway that drives cancer-related bone pain while providing a potential solution with a drug that already is on the market.
The mystery of how human eyes compute the direction of moving light has been made clearer by scientists at The University of Queensland.
Calculating a person's waist-to-height ratio is the most accurate and efficient way of identifying whether or not they are at risk of obesity in clinical practice, a new study by Leeds Beckett University shows.
A newly discovered mechanism behind reduced insulin production in type 2 diabetes is now being presented.
