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.
Many of us have noted how our hands and feet swell after eating too much salt. Now scientists are exploring how high salt intake can also make cells throughout the body of females swell, rupture, dump their contents and die, triggering an immune reaction that contributes to chronic high blood pressure.
Reducing sodium in the diet has been recommended to lower blood pressure and the risk of heart disease.
A Michigan State University breast cancer researcher has shown that effective treatment options can be predicted based on the way certain breast cancer genes act or express themselves.
Nathan Schmidt, Ph.D., has published research showing that microbes in the gut of mice can affect the severity of illness suffered from infection with Plasmodium, the parasite that causes malaria.
Researchers in RCSI (Royal College of Surgeons in Ireland) have conducted further in-depth research to predict how patients with bowel (colorectal) cancer will respond effectively to chemotherapy, to ensure that patients will get the most suitable type of treatment from the outset.
Researchers from Universidad Politécnica de Madrid have calculated for the first time the real energy expenditure in different training programs, including both aerobic and anaerobic contribution.
Treatment options for liver cancer are often limited and almost exclusively involve transplantation if possible, or local chemoembolization and radiofrequency ablation.
The community of microorganisms that resides in the gut, known as the microbiome, has been shown to work in tandem with the genes of a host organism to regulate insulin secretion, a key variable in the onset of the metabolic disease diabetes.
In the current issue of Psychotherapy and Psychosomatic Dr. Ralph Horwitz and colleagues outline new methodologies, in addition to the well-known randomized controlled trials, to gather information that may lead to individualized patient care.
With new funding from The Mayday Fund, a Saint Louis University researcher will leverage her discovery of a pain pathway to determine if either of two key molecules can be used as biomarkers for pain associated with four debilitating health conditions: chemotherapy-induced peripheral neuropathy, endometriosis, interstitial cystitis and vulvodynia.
A new test using peripheral vision reaction time could lead to earlier diagnosis and more effective treatment of mild traumatic brain injury, often referred to as a concussion, according to Peter J. Bergold, PhD, professor of physiology and pharmacology at SUNY Downstate Medical Center and corresponding author of a study newly published online by the Journal of Neurotrauma.
Does the biological clock in cancer cells influence tumour growth? Yes, according to a study conducted by Nicolas Cermakian, a professor in McGill University's Department of Psychiatry.
Dr Jonathan Peake and Dr Oliver Neubauer, from QUT's Institute of Health and Biomedical Innovation, led a research review of studies about exercise and immunity.
A father's nicotine use may have a significant impact on children's risk of some diseases. In a study published in the online biomedical sciences journal eLife, Oliver J. Rando, MD, PhD, and colleagues at UMass Medical School, demonstrate that mice born of fathers who are habitually exposed to nicotine inherit enhanced chemical tolerance and drug clearance abilities.
Burn patients need support to transition to burn survivors. That's why Thereasa Abrams, an assistant professor in the University of Tennessee, Knoxville's College of Social Work and a burn survivor herself, has developed an app called the Bridge to help them heal faster.
A newly discovered mutation in the INPP5K gene, which leads to short stature, muscle weakness, intellectual disability, and cataracts, suggests a new type of congenital muscular dystrophy.
A new study finds that concussion causes short-term impairment of the cardiovascular system but that these cardiovascular symptoms typically resolve within three days of the injury.
An international research team has discovered that the IFT20 protein helps some cancer cells to invade by facilitating the transportation of membranes and proteins within parts of the cell.
In the outpatient clinic and in the laboratory our current research studies aim at understanding the mechanisms of release and clearance and the biological functions of exosomes and membrane particles in the plasma of individuals who develop emphysema, a form of chronic obstructive pulmonary disease characterized by enlargement of airspaces and loss of alveoli.
The University of Massachusetts Amherst recently licensed a new technology to Janssen Pharmaceuticals, Inc. that holds promise of revolutionizing the treatment of cataracts and presbyopia, based on early phase discoveries by polymer physicist Murugappan Muthukumar and former graduate student Ben Mohr regarding the fundamental science of proteins in the lens of the human eye.
