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.
Leading CAR T cell therapy researchers have developed a human-in-the-loop artificial intelligence (AI) framework that firmly centers scientists' expertise to find viable target antigens for CAR T cell therapy.
Your body absorbs alcohol much more rapidly after bariatric surgery. Patients need to know this when they choose the kind of surgery they will have.
New research sheds light on why red meat may worsen inflammatory bowel disease (IBD) - and how other protein sources could help protect the gut.
A prospective European cohort study found that one season of competitive youth soccer was not associated with detectable short-term differences in cognition, behavior, balance, MRI measures, or blood biomarkers compared with noncontact sports. However, soccer players had higher preseason tNAA, GFAP, and NfL levels than controls, highlighting the need for larger, multiyear studies to clarify whether repeated heading has cumulative effects.
A revolutionary protective shoe concept adapts to the needs of users in a new way and provides increased comfort and minimizes strain.
The body's organs are in constant communication. Fat tissue tells the liver when to store or release energy, the immune system signals localized inflammation, and thousands of proteins carry these messages to organs throughout the body.
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.
