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.
Following a $13.48 million dollar award from the defense department, a team of engineers and surgeons from Johns Hopkins Medicine have published their first proof-of-concept study that shows temporarily implanting a tiny ultrasonic device into the location of a spinal cord injury can be feasible, safe and potentially useful.
A particular signaling protein in the brain could be a therapeutic target for neurological disorders arising from the deletion of the autism-linked gene MEF2C, University of Illinois Urbana-Champaign researchers found in a new mouse study.
A global study of 1,015 adults across 12 countries found that industrialized lifestyles were associated with lower gut bacterial diversity, reduced microbial community stability, and increased markers of intestinal stress and immune activity. The researchers also found that a microbiome-based health index developed using industrialized populations performed poorly in less-industrialized communities, raising concerns about its applicability across diverse populations.
If you can remember your first sip of coffee, the memory might not be a pleasant one. Coffee's bitter flavor is one we naturally steer clear of. So how do coffee fans learn to love it?
Research out of South Dakota State University has highlighted a potential connection between limited exposure to cold stress during pregnancy and birth weight.
In a study of 193 participants, researchers found that blood-based short-chain fatty acid profiles distinguished colorectal cancer, celiac disease, obesity, and healthy controls with 95% accuracy, compared with 59% for stool-based measurements. Combining blood and stool profiles increased accuracy to 97%, suggesting that circulating microbial metabolites may offer valuable diagnostic information, although larger studies are needed to validate the findings.
When you’re going through cancer treatment or recovering afterwards, rest might seem like the best medicine.
When you're going through cancer treatment or recovering afterwards, rest might seem like the best medicine. But research shows that exercise can also play an important role in managing cancer recovery.
Critical care requires rapid decisions from complex, evolving data. Predictive models forecast deterioration but do not guide therapy.
A review published in the British Journal of Nutrition examines how carotenoids and bioactive compounds in Brassicaceae microgreens may influence obesity, insulin resistance, and type 2 diabetes through metabolic and inflammatory pathways. Small human trials involving broccoli sprouts have reported improvements in selected metabolic markers, but larger, longer-term studies are needed to establish their clinical benefits.
Yale School of Medicine (YSM) was awarded a $10 million grant from the Blavatnik Family Foundation (BFF) to launch a new research initiative in the field of inflammation science.
Researchers reviewed animal and human studies and found that ketone bodies may affect sleep stages through energy metabolism and cellular signaling, with the clearest direct evidence involving acetoacetate in mice. They reported mixed human findings and called for controlled studies to separate ketone-specific effects from changes linked to diet, disease, circadian timing, and physiological stress.
Researchers compared semaglutide-treated male and female rats with pair-fed animals receiving the same amount and type of food to distinguish drug-associated microbiome changes from those linked to reduced eating. Semaglutide altered bacterial richness and community composition, with some changes absent from the pair-fed groups and uncertain consequences for health.
Mitochondria are the tiny powerpacks that supply most of the energy our cells need. Their ability to generate this energy relies on a distinctive architecture: two membranes, one tucked inside the other, separated by a narrow gap called the intermembrane space (IMS).
Major new research published today identifies potential new ways to treat the most common type of bowel cancer in Ireland.
A Michigan Medicine-led research consortium has secured approval for up to $52 million in federal funding to launch a multicenter study examining why some young children recover fully from viral lower respiratory tract infections while others develop severe illness or lasting problems such as asthma.
Scandinavian Real Heart AB today announces that a new peer-reviewed study published in the scientific journal Platelets demonstrates preserved platelet function following circulation in the Realheart® Total Artificial Heart (TAH).
When analyzed by a new artificial intelligence model developed at Penn Medicine, CT scans reveal much about a patient's health beyond the specific condition they were originally ordered for, according to a new study published in NPJ Digital Medicine.
A protein called Miro1 found at elevated levels in the skeletal muscle of people with Type 2 diabetes may contribute to insulin resistance, potentially making it a target for future treatments that help the body regulate blood sugar, according to a study published today in Nature Communications.
Heart failure (HF) alters the bone marrow (BM), reducing protective cells that regulate inflammation, reports a study conducted at Science Tokyo.
