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.
Patients with a common form of kidney cancer called clear cell renal cell carcinoma (ccRCC) who have a high risk of recurrence after surgery showed significantly improved disease-free survival when treated with an oral combination regimen that includes belzutifan, a HIF-2α inhibitor, given with standard immune therapy pembrolizumab.
In 2021, a technology developed at University of Michigan, called Seq-Scope, revolutionized the ability to map gene activity within intact tissue at microscopic resolution, enabling researchers to measure all expressed mRNA molecules and determine precisely where they are located within the tissue, using an Illumina sequencer machine.
New research by engineers at the University of Colorado Boulder aims to get to the bottom of why, as the saying goes, you get a "skip in your step" when you're happy.
Gene therapy has been successfully used to treat a number of diseases, including immune deficiencies, hereditary blindness, hemophilia and, recently, Huntington's disease, a fatal neurological disorder.
Study reveals how two proteins cooperate in a key early step of antiviral detection, as reported by researchers at Science Tokyo.
Plastic products are ubiquitous in our food supply chain, shedding microplastics into every part of the human ecosystem.
A ketogenic diet - one that is high in fat and extremely low in carbohydrates - has been known for decades to reduce seizures in some epilepsy patients.
Research in Aging Cell indicates that blood levels of particular small non-coding RNAs, which regulate gene expression, may influence how long a person lives.
A new study published in Ecological and Evolutionary Physiology reveals a surprising link between cellular aging markers and survival in black-legged kittiwakes (members of the gull family).
Aleksey Maro knows far more than he cares to know about the urination habits of chimpanzees. But if you want to measure the alcohol intake of chimps in a Ugandan rain forest, where a breathalyzer is impractical, collecting urine for analysis is your only choice.
In a 12-week randomized phase IIa trial in adults with obesity, the dual GLP-1/GLP-2 receptor agonist dapiglutide was well tolerated but did not achieve statistically significant weight loss compared with placebo at 4 mg or 6 mg doses. Although the higher dose showed modest within-group weight reduction and improved HbA1c, unexpectedly substantial placebo-associated weight loss limited the observed treatment effect.
An EHU study indicates that a drug already approved for use in humans could help to reduce the inflammation associated with celiac disease.
Autophagy is indispensable for maintaining hepatocyte integrity, metabolic homeostasis, and survival. While several autophagy-related proteins have been studied in hepatic physiology, the specific role of Autophagy Related 14 (ATG14) in liver health has remained unclear.
In Switzerland, 0.02% of the population lives beyond the age of 100. Could there be biological characteristics associated with this exceptional longevity? As part of the "SWISS100" study, the first large-scale Swiss research project dedicated to centenarians, a team from the University of Geneva (UNIGE) and the University of Lausanne (UNIL) compared the blood profiles of centenarians with those of octogenarians, and then with those of individuals aged 30 to 60.
Proteins long known to be essential for hearing have been hiding a talent: they also act as gatekeepers that shuffle fatty molecules across cell membranes.
Why do some people feel chills when listening to music, reading poetry, or viewing a powerful work of art, while others do not? New research by Giacomo Bignardi and his colleagues from Max Planck Institute for Psycholinguistics (MPI) published in PLOS Genetics reveals that part of the answer lies in our genes.
Chronic pain lasts longer for women than men, and new research suggests differences in hormone-regulated immune cells, called monocytes, may help explain why.
Scientists have long known that people living at high altitudes, where oxygen levels are low, have lower rates of diabetes than people living closer to sea level.
Past studies in animals have shown that a highly processed diet is linked to memory problems and inflammation in the aged brain – and the effect can happen fast, after just three days of poor eating.
In a 2023 paper on hypoxia and glucose metabolism, our lab showed how organisms rewire their metabolism to adapt to low oxygen levels-such as those found at high altitudes.
