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 pilot study published today in Communications Medicine demonstrates the potential of a new approach to treating anorexia nervosa - a disorder for which effective treatments have been significantly limited.
Perioperative anaphylaxis is a rare, life‑threatening condition during anesthesia. The unique setting – multiple drugs, patient draping, and altered physiology – causes higher mortality than anaphylaxis elsewhere.
Researchers have found that consuming lower amounts of protein-rich foods may negatively affect physical functioning as people grow older, underscoring the vital function protein plays in preserving mobility and muscle strength in adulthood.
A Mount Sinai-led research team has demonstrated that autoimmunity, where the body's immune system attacks its own tissues, is responsible for the often-debilitating and confounding symptoms of long COVID in a subset of people.
Science and art have been brought together in a series of new projects led by a Kingston University academic, challenging the stigma surrounding the menopause and women's health through a groundbreaking body of work featured in several prestigious exhibitions this summer.
A study on 42,759 menstrual cycles shows that sleep quality affects menstrual health, with implications for physiological stability and individual variability.
Digital health tools, including wearables, provide critical data on menstrual health, enhancing understanding of hormonal fluctuations and women's well-being.
This review examines how gut keystone bacteria shape microbiome stability, disease risk, and responses to diet. It highlights why better identification methods, experimental validation, and precision diet-probiotic strategies are needed to restore gut homeostasis.
Megan Sweet slices tumors. A normal day in the lab finds the Virginia Tech graduate student with hands deep inside a refrigerated metal box, pulling a mounted mouse-grown tumor incrementally closer to a razor-sharp blade.
A rapidly advancing area of biomedical innovation is shining a spotlight on miR-128-3p, a small yet powerful molecule with the potential to reshape how diseases—especially cancer—are detected, monitored, and treated. This microRNA, part of a broader class of non-coding RNAs, plays a critical role in regulating gene activity and maintaining cellular homeostasis.
This systematic review found that yoga and Buddhist meditation were associated with favorable gut microbiota and metabolite profiles in four human studies involving healthy adults. However, because participants largely followed vegetarian or vegan diets and no randomized controlled trials were included, the findings cannot prove that meditation alone reshapes the gut microbiome.
A new review highlights how synthetic biology, AI, and spatial omics could transform ligand-receptor discovery from one-by-one searches into network-level mapping.
Researchers found that more than half of urban rats sampled from low-income communities in Salvador, Brazil, carried active pharmaceutical ingredients in their brain tissue. These pollutants were associated with altered zoonotic infection patterns, including lower Leptospira infection probability in rats carrying azithromycin and higher Capillaria infection probability in rats carrying citalopram.
Bone is continuously renewed through a process known as bone remodeling, in which osteoblasts (bone-forming cells) build new bone, while osteoclasts (bone-resorbing cells) remove older mineralized tissue.
Fibrous dysplasia is a rare skeletal disorder in which normal bone is gradually replaced by weak fibro-osseous tissue, leading to fractures, pain, deformities, and severe mobility impairment. In many patients, diseased bone tissue produces excessive amounts of fibroblast growth factor-23 (FGF23), a hormone that causes phosphate loss through the kidneys.
Inflammatory bowel disease (IBD), which comprises the inflammatory conditions Crohn's disease and ulcerative colitis, affects about 1.6 million Americans, many of whom cannot be effectively treated.
The EuroPCR Course Directors have selected 3 major late-breaking trials that will be presented for the first time during EuroPCR 2026 and are set to impact practice worldwide.
Researchers at Rutgers University-New Brunswick are working to measure pain more accurately beyond the single, subjective question patients are often asked: "On a scale of 1 to 10, how bad is your pain?"
Cyclana Bio, a biotechnology company pioneering tissue-level approaches to women’s health, today announced it has received Health Research Authority (HRA) and Research Ethics Committee (REC) approval for its 500-patient clinical observational study, PEMP (Predicting Endometriosis Mechanisms and Populations).
A novel wireless chest patch enables continuous monitoring of stress signals, enhancing psychophysiological assessment in clinical and real-world settings.
