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.

Exposure to blue-green algae toxin shown to wreak havoc on gut bacteria and cause liver damage

Exposure to a specific type of blue-green algae toxin known as cylindrospermopsin has shown to wreak havoc on gut bacteria and an increased probability of irritable bowel syndrome, inflammatory bowel disease, celiac disease, type 1 diabetes, obesity and inflammation of the liver – a precursor to liver cancer – according to a study led by the University of California, Irvine.

Long-lived Chilean rodent is a useful model of natural sporadic Alzheimer's Disease

Led by researchers from the University of California at Irvine, a new study reveals that a long-lived Chilean rodent, called Octodon degus (degu), is a useful and practical model of natural sporadic Alzheimer's Disease.

Researchers show how motor memory is consolidated during sleep

When the Golden State Warriors' Steph Curry makes a free throw, his brain draws on motor memory. Now researchers at UC San Francisco have shown how this type of memory is consolidated during sleep, when the brain processes the day's learning to make the physical act of doing something subconscious.

Gut-dwelling bacteria can promote the desire to exercise, study shows

Some species of gut-dwelling bacteria activate nerves in the gut to promote the desire to exercise, according to a study in mice that was led by researchers at the Perelman School of Medicine at the University of Pennsylvania.

Study identifies Δ42PD-1 as novel therapeutic target for hepatocellular carcinoma immunotherapy

HKUMed researchers at AIDS Institute, Department of Microbiology and Department of Surgery, School of Clinical Medicine, and School of Biomedical Sciences discover the role of an isoformic programmed cell death protein 1 (PD-1), namely Δ42PD-1, in suppressing the function of killer T cells, which is a type of immune cells essential for killing cancer cells among hepatocellular carcinoma (HCC) patients.

Extraordinary plasticity of the glucocorticoid receptor revealed

Glucocorticoids —such as cortisone— are among the most widely used anti-inflammatory drugs, and are used to treat asthma, psoriasis, organ transplantation and even COVID-19.

Study reveals limited effects of longevity treatments on the aging process

Three approaches with a reputation for slowing aging processes have proven largely ineffective. For their study, researchers developed a new method to measure aging, which accounts for the complexity of aging in organisms.

Multiomics analysis of kidney metabolism reveals a gatekeeper for viral infections

Our kidney filters 180 liters of blood every day and retains nutrients through a process called 'endocytosis' and through active transport in the kidney cells.
