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.

Researchers shed light on an important stage of early human embryogenesis for the first time

Scientists have shed light on an important stage of early embryonic development that has never been fully mapped out in humans before.

Impact of ultraviolet disinfection on nosocomial transmission of SARS-CoV-2 and other infectious diseases

A new review article determines the role of UV disinfection for nosocomial transmission of COVID-19 and other infectious diseases.

GABA secreted by B-cells blunts the body's cytotoxic T-cell-based response to tumors

A group of scientists led by researchers from the RIKEN Center for Integrative Medical Sciences have discovered that B-cells, a type of immune cell, secrete the neurotransmitter GABA, and also found that the GABA secreted by the B-cells promoted the emergence of anti-inflammatory macrophages, blunting the body's cytotoxic T-cell-based response to tumors.

Heart rates of older couples synchronize when they are close together

As couples grow old together, their interdependence heightens. Often, they become each other's primary source of physical and emotional support.

Stem cell enlargement contributes to decline in normal function during aging

MIT biologists have answered an important biological question: Why do cells control their size? Cells of the same type are strikingly uniform in size, while cell size differs between different cell types. This raises the question of whether cell size is important for cellular physiology.

Microbiome discovery may help improve treatment for patients with gastrointestinal diseases

University of Calgary researchers probing the gut - "the inner tube of life" - have for the first time discovered specific factors in its workings that in the future may help improve treatment for patients facing gut damage or gastrointestinal disease.

Macrophages located in the cardiac tissue protect the failing heart

According to the Centers for Disease Control and Prevention, heart failure affects more than 6 million Americans and is the main cause of death for one in eight patients.

Reduced levels of coenzyme A may exacerbate cardiac dysfunction during heart failure

Reduced levels of coenzyme A (CoA) worsen heart failure and likely help exacerbate cardiac dysfunction during heart failure, according to a new study.

Researchers discover mechanisms underlying the unwanted side effects of drugs

Researchers at Weill Cornell Medicine have discovered how drugs can affect various membrane-spanning proteins in addition to their intended target, potentially causing unwanted side effects.

Ion channel mechanosensor plays a key role in regulating the speed of skin wound healing

PIEZO1, an ion channel mechanosensor found within cells, has been revealed to play a key role in regulating the speed of skin wound healing by researchers at the University of California, Irvine.

Oral drug works just as well as conventional therapy for anemia in patients with kidney disease

Anemia is a common and sometimes debilitating problem among patients with chronic kidney disease (CKD). Anemia can occur when the kidneys become damaged, limiting the production of erythropoietin (EPO) - a hormone that signals to the body to make red blood cells.

Experts gain insights into pathomechanisms of dilated cardiomyopathy

Titin is a "titanically large" protein – the largest in the human body – which enables elastic movements of our muscles, including the heart.

“Catching SARS-CoV-2 in the act” – viral infection of nasal mucosa spares nerve cells

A new study discusses the entry of SARS-CoV-2 into the respiratory and olfactory mucosa of the nasal cavity.

Study shows aberrant changes over time in the brains of people with bipolar disorder

Bipolar disorder (BD) is a debilitating psychiatric disorder characterized by fluctuating periods of depression and mania.

Study paves the way for a better understanding of muscle injury

Researchers from the INCLIVA Health Research Institute, the Clinical Hospital of Valencia, and the University of Valencia (UV) have participated in a study, the results of which have just been published in Science, which paves the way for a better understanding of muscle injury.
