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.

Damaging effects of blue light exposure worsen with age

The damaging effects of daily, lifelong exposure to the blue light emanating from phones, computers and household fixtures worsen as a person ages, new research by Oregon State University suggests.

Elevated insulin resistance, advanced cell aging associated with childhood poverty

Black adolescents who lived in poverty and were less optimistic about the future showed accelerated aging in their immune cells and were more likely to have elevated insulin resistance at ages 25-29, researchers found.

Research reveals molecular clues associated with traumatic brain injury

New research led by scientists at Arizona State University has revealed some of the first detailed molecular clues associated with one of the leading causes of death and disability, a condition known as traumatic brain injury (TBI).

Two UTHSC research teams receive CORNET Awards for novel projects

Two research teams at the University of Tennessee Health Science Center (UTHSC) have been awarded the 2022 UTHSC Collaborative Research Network (CORNET)-Functional Genomics Award. Each team will receive $50,000 to support their novel projects.

Study finds white adipose tissue to be the most vulnerable organ to obesity-related metabolic changes

When the body is subjected to a high-calorie diet, the physiological response is not homogeneous and some organs or tissues are more sensitive to metabolic stress.

Remote ischemic preconditioning can amplify the protection against heart attack, stroke

The majority of heart attacks and strokes in the world are ischemic, meaning a clot or buildup of plaque in an artery prevents oxygen-rich blood from reaching cells in the heart or brain. Blocked for too long, tissues die.

Elephant genes could offer new clues to preventing cancer development

Scientists modeling the cancer-suppressing p53 gene identify how the 20 different molecules unique to elephants get activated for increased sensitivity and response against carcinogenic conditions - with implications for cancer treatments in humans.

Researchers find link between brain protein and increased vulnerability to neurodegeneration in epilepsy patients

A team of Florida State University College of Medicine researchers has found a link between a specific protein in the brain and increased vulnerability to neurodegeneration for individuals with temporal lobe epilepsy (TLE).

Alternative therapy based on S100A9 protein improves metabolism of insulin-dependent diabetics

People with a severe form of diabetes, where the beta cells of the pancreas do not produce or no longer produce enough insulin, have no choice but to inject themselves regularly with artificial insulin in order to survive.

Study provides new insights into the process of memory recall

An unforgettable time at a restaurant is not just about the food. The odors, the decor, the sound of the band playing, the conversations, and many other features may combine to form a distinctive memory of the night.

Neuroscience simulations at NERSC reveal the origin of the cortical surface electrical signals

Where does electrical activity recorded on the surface of the brain come from, and what exactly determines which electrical signals get recorded?

Pulse oximeter inaccuracies may be associated with racial disparities in care

For most patients, a pulse oximeter is a familiar device from visits to the doctor's office. Placed on a finger or a patient's ear lobe, pulse oximeters are an easy way to quickly get a measure of someone's oxygen saturation (SpO2), which should generally be above 90 percent.

Study illustrates how the use of whole exome sequencing can better predict treatment response

Immunotherapies, such as immune checkpoint inhibitors, have transformed the treatment of advanced stage cancers.

Study finds microglia to be responsible for neuronal death in a mitochondrial disease animal model

Microglia, a type of central nervous system cell, is primarily responsible for neuronal death in Leigh Syndrome and the neurological symptoms related to this mitochondrial disease.

The role of myostatin in female fertility

A new study discusses some of the key functions of myostatin in female reproductive health and disease.

Researchers challenge centuries-old beliefs about limb regeneration

Ken Muneoka is no stranger to disrupting the field of regeneration; for example, in a 2019 ground-breaking publication in Nature, the Texas A&M University College of Veterinary Medicine & Biomedical Sciences professor proved for the first time that joint regeneration in mammals was possible.
