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.
Researchers from the University of Birmingham have found that extended rest intervals between sets of weight-lifting could help with muscle growth.
The autoimmune disorder Sjogren's syndrome is often overlooked or misdiagnosed because the symptoms are similar to other conditions. Its characteristic symptoms are dry eyes and dry mouth, and reduced tear production is used as part of the diagnosis.
Individual small RNAs are responsible for controlling the expression of gonadoliberin or GnRH (Gonadotropin-Releasing Hormone), a neurohormone that controls sexual maturation, the appearance of puberty, and fertility in adults.
Women with poor physical fitness display significantly higher platelet activation than women with average to very good fitness. That is the major finding of a study of 62 young women, conducted by the research groups of Ivo Volf and Rochus Pokan and sponsored by the Austrian Heart Foundation. Platelet (thrombocyte) activation can lead to the formation of potentially life-threatening blood clots.
Research led by SUNY Downstate Medical Center has identified a brain receptor that appears to initiate adolescent synaptic pruning, a process believed necessary for learning, but one that appears to go awry in both autism and schizophrenia.
Newly discovered genetic switches that increase lifespan and boost fitness in worms are also linked to increased lifespan in mammals, offering hope that drugs to flip these switches could improve human metabolic function and increase longevity.
Researchers have known for more than a decade that the risk of heart disease and stroke increases when people take pain relievers like ibuprofen and other non-steroidal anti-inflammatory drugs, or NSAIDs. Now, scientists from the University of California, Davis, have uncovered some of the reasons why these drugs can harm heart tissue.
Cellular and Molecular Gastroenterology and Hepatology is committed to publishing impactful digestive biology research covering a broad spectrum of themes in GI, hepatology and pancreatology. We wanted to share two new CMGH articles, which both offer important insight into future interventions for chronic conditions.
Female hormones may play a role in women's decreased risk of developing kidney failure relative to men, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology. The findings may be helpful for future attempts at safeguarding women's and men's kidney health in sex-specific ways.
It's an unsettling thought: You could be walking around for 20 years developing Parkinson's disease and not even know it.
Vitamin A is involved in many bodily processes, including vision and skin health, but its role in the heart is unclear. While vitamin A is critical for heart development of embryos—vitamin A deficiency during pregnancy leads to an abnormal heart and prenatal death—studies on vitamin A's role in heart health have drawn opposite conclusions.
Changes in key genes clearly define four previously unknown conditions within the umbrella diagnosis of schizophrenia, according to a study led by researchers from NYU Langone Medical Center published online April 28 in EBioMedicine, a Lancet journal. Cases associated with changes in each of the four genes were different from each other in terms of symptoms, intelligence level and other disease features.
While the Fontan procedure has improved the short- and mid-term outcomes for patients born with single ventricle anatomy, long-term complications of Fontan circulation include heart failure. These complications are thought to be secondary to elevated central venous pressure, chronic venous congestion and low cardiac output.
A new study published in the British Journal of Nutrition appears to back up the adage that a little of what you fancy does you good.
A compact PET scanner called NuPET has been commercially released for simultaneous preclinical PET (Positron Emission Tomography) and MRI (Magnetic Resonance Imaging) in existing third-party MRI systems.
A group including scientists from the Florida campus of The Scripps Research Institute (TSRI) has been awarded a grant from the National Institute of Neurological Disorders and Stroke of the National Institutes of Health to study the role of microRNAs in a range of physiological activities, including memory, sleep, synapse function and movement.
When human cells are exposed to titanium dioxide without the presence of UV light from the sun, the risk for bacterial infection more than doubles. This finding by a Stony Brook University-led research team, published early online in the Journal of Nanobiotechnology, raises concerns about exposure to titanium dioxide, a nanoparticle commonly used in millions of products worldwide ranging from cosmetics to toothpaste, gum, food coloring, and medicines.
Transport plays a major role in the spread of transmissible diseases. PANDHUB, a project coordinated by VTT Technical Research Centre of Finland Ltd, develops ways of reducing the risk of pandemics and managing other high-threat pathogen incidents in transport hubs.
A new study shows the death of newborn brain cells may be linked to a genetic risk factor for five major psychiatric diseases, and at the same time shows a compound currently being developed for use in humans may have therapeutic value for these diseases by preventing the cells from dying.
Fragile X syndrome (FXS) is the most common genetically inherited cause of intellectual disability in humans. New research shows how the hormone insulin -- usually associated with diabetes -- is involved in the daily activity patterns and cognitive deficits in the fruitfly model of FXS, according to a new study from the Perelman School of Medicine at the University of Pennsylvania published online this month in Molecular Psychiatry in advance of the print issue.
