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.

Regulation of fat production is abnormal in obesity, shows study

Gut hormones play an important role in regulating fat production in the body. One key hormone, released a few hours after eating, turns off fat production by regulating gene expression in the liver, but this regulation is abnormal in obesity, researchers at the University of Illinois Urbana-Champaign found in a new study.

Researchers launch study to determine effects of increased access to rapid COVID-19 testing

Researchers at the University of Chicago Medicine and the University of Illinois at Chicago (UIC) are launching an investigational study to determine the effects of increased education and access to rapid, FDA-approved COVID-19 testing on community perceptions, access, and use of COVID-19 testing resources.

Consumption of dried fruit may be connected with better health

Don't be afraid to toss a handful of raisins or dried apples in your Thanksgiving stuffing this year -- a new Penn State study has found that dried fruit may be connected with better health.

Hormone that suppresses food intake could be used as potential treatment for obesity

A hormone that can suppress food intake and increase the feeling of fullness in mice has shown similar results in humans and non-human primates, says a new study published today in eLife.

Potential treatment could reduce heart failure after a significant heart attack

While there are therapies to aid in overall heart health, there are very few preventative therapies for heart failure after a significant heart attack, a serious condition that has a very significant mortality.

Molecular action of tarantula toxin may hold clues to better control of chronic pain

Oversized, hairy tarantulas may be unsightly and venomous, but surprisingly their hunter toxin may hold answers to better control of chronic pain.

Study uncovers an unexpected social life of giant poisonous rats

The African crested rat (Lophiomys imhausi) is hardly the continent's most fearsome-looking creature--the rabbit-sized rodent resembles a gray puffball crossed with a skunk--yet its fur is packed with a poison so lethal it can fell an elephant and just a few milligrams can kill a human.

Neuronal population dynamics in the motor cortex are different for reach and grasp behaviors

A new study from researchers at the University of Chicago has found that neuronal population dynamics in the motor cortex are very different during reaching and grasping behavior, challenging a popular theory that indicated intrinsic, dynamic patterns control motor behaviors.

Study demonstrates 24-hour rat liver viability in a normothermic machine perfusion system

In a paper published in TECHNOLOGY, a team of researchers from Massachusetts General Hospital (MGH) has demonstrated 24-hour rat liver viability in a normothermic machine perfusion (NMP) system.

LOX plays a number of key roles in promoting skin and organ fibrosis in scleroderma

A team of researchers at the Medical University of South Carolina (MUSC) has found that the molecule lysyl oxidase (LOX) plays a number of important roles in promoting skin and organ fibrosis in scleroderma, a connective tissue disorder.

Existing UV light technology has potential to be effective against Covid-19

A recent study has shown that a UV light technology already used to prevent the spread of other airborne diseases in buildings has the potential to be effective against Covid-19.

Facemasks do not diminish lung function during physical activity, shows study

Wearing a facemask helps limit the spread of COVID-19 by reducing respiratory droplets and aerosols spewed into the air when people breathe, talk, laugh, sneeze or cough.

Scientists reveal new evidence of electrical pathway in the heart

These days having both a land line and a mobile phone seems like overkill. But Virginia Tech researchers have shown that the heart relies on at least two key communication channels to keep abnormal heart rhythms in check.
