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.
A new finding by a Virginia Tech neuroscientist at the Fralin Biomedical Research Institute at VTC is challenging the way investigators study chronic neurological disorders such as dystonia, ataxia, and tremor.
A 28-day wearable-sensor study of 26 healthy naturally menstruating women found that active energy expenditure varied across the menstrual cycle and was higher in the early follicular phase than the late follicular phase.
A cross-University paper led by researchers at Queen Mary University of London, published in the Journal of Physiology shows how better 'digital twins' could help doctors treating people with Atrial Fibrillation.
A narrative review found that tight-fitting underwear may modestly raise scrotal temperature and is inconsistently linked to lower sperm production measures. However, current evidence does not show that switching to looser underwear improves real-world fertility outcomes.
Consider what we ask of a clinical trial. We gather people who differ in nearly every way that matters, we give them the same drug at the same dose, and then we average the result and call the average truth.
Mayo Clinic researchers have identified a previously unrecognized way the kidneys regulate water balance - an advance that could lead to improved treatments for polycystic kidney disease (PKD) and other disorders. The study, led by Fouad Chebib, M.D., a nephrologist at Mayo Clinic, is published in the Journal of Clinical Investigation.
Synthetic cooling ingredients added to e-cigarettes caused abnormal heartbeats (arrhythmias) and increased cardiovascular risk measures in mice and lab-grown human heart cells, according to new independent research published today in Circulation: Arrhythmia and Electrophysiology, a peer-reviewed journal of the American Heart Association.
In this interview, News-Medical talks to Marcin Pacek, senior director of medical and scientific affairs in
Europe for Nova Biomedical, about the importance of ketones in a medical and clinical setting.
Male rats that were exposed to the widely used plasticizer di-(2-ethylhexyl) phthalate (DEHP) during early development exhibited increased anxiety behavior as adults, according to a study being presented Saturday at ENDO 2026, the Endocrine Society's annual meeting in Chicago, Ill.
The U.S. Food and Drug Administration (FDA) has approved pembrolizumab, an immunotherapy, plus belzutifan, a HIF-2α inhibitor, as adjuvant treatment for adult patients with renal cell carcinoma with a clear cell component (ccRCC) at intermediate-high or high risk of recurrence following nephrectomy, with or without resection of metastatic lesions.
A molecular geneticist at Montana State University has discovered a cellular process once believed impossible by scientists – the creation of the amino acid cysteine within a living cell when the cell's primary systems to do so fail. The discovery may one day lead to new cancer treatments.
Blood pressure management after thrombectomy for acute ischemic stroke may require a change in approach.
A new treatment platform developed by researchers at The University of Texas MD Anderson Cancer Center was able to deliver messenger RNA (mRNA) of the full-length DMD gene into preclinical models of Duchenne muscular dystrophy, successfully restoring the production of an important muscle protein, dystrophin, and dramatically improving muscle strength, endurance and function in vivo.
A US cause-specific modeling study found no net protective health effect from low-level alcohol consumption, with lifetime alcohol-attributable mortality risk rising above 1 in 1,000 at just over 6.5 drinks per week for males and 7.0 drinks per week for females.
Women who engage in light physical activity and lessen their sedentary time may significantly reduce the risk of key health problems during pregnancy, according to a new University of Iowa-led study.
Cognitive behavioral therapies for insomnia (CBT-I) are increasingly being delivered online in order to improve accessibility.
New research highlights fathers' influence on childhood obesity risk through sperm changes, lifestyle, and parenting, urging inclusive prevention strategies.
A growing body of research suggests that a father's health before conception may play a larger role in child development than previously understood - and researchers are working to understand how a father's drinking before conception may affect offspring health and development.
Studies in mice reveal a new target for potentially treating and preventing life-threatening cardiovascular complications in the millions of patients with sleep apnea worldwide.
Alzheimer's disease and related dementias are expected to more than double by 2060. As June marks Alzheimer's and Brain Awareness Month, three University of Florida researchers are working to improve clinicians' ability to distinguish between these diseases - a critical step toward earlier diagnosis and better outcomes.
