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.

Irregularities in sleep timing and duration linked with increased risk of hypertension

A study of more than two million nights of sleep and blood pressure data found that irregularities in sleep timing and duration were associated with an increased risk of hypertension.

USC scientists receive more than $16 million to study the role of blood vessel dysfunction in Alzheimer’s disease

The National Institute on Aging, a division of the National Institutes of Health, awarded Berislav Zlokovic, MD, PhD, director of the Zilkha Neurogenetic Institute, and Arthur W. Toga, PhD, director of the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI), $16.1 million to continue research on the role that blood vessel dysfunction plays in the development of dementia and Alzheimer's disease.

Oral administration of rapamycin increases β-amyloid buildup in Alzheimer's disease mouse model

Researchers from The University of Texas Health Science Center at San Antonio (UT Health San Antonio) have found that oral administration of rapamycin to an Alzheimer's disease mouse model causes an increase in beta (β)-amyloid protein plaques. β-amyloid buildup is a hallmark of Alzheimer's disease.

Discovery may lead to new treatments to reduce inflammation in vitiligo disease

A new study, led by researchers from the University of California, Irvine, reveals the unique cell-to-cell communication networks that can perpetuate inflammation and prevent repigmentation in patients with vitiligo disease.

Color-changing mouse model aids in better visualization of internal physiology

Biomedical and genetic engineers at Duke University and the Albert Einstein College of Medicine have developed a process to change the color of a mouse's tissue in imaging to better visualize its internal physiology.

Short 20-minute power naps during night shifts can help improve hospital staff and patient safety

A review at this year's Euroanaesthesia congress in Milan, Italy (4-6 June) on the potentially lethal effects of fatigue on doctors and nurses themselves, and its impact on the quality of their clinical work and judgment and therefore patient safety, will be given by Consultant Anaesthetist Dr Nancy Redfern of Newcastle Hospitals NHS Foundation Trust, Newcastle, UK.

Ultrasound localization microscopy can image microscopic vessels and measure blood flow in the brain

To image microscopic vessels and measure blood flow in the brain, researchers use a tool called ultrasound localization microscopy. It works by using microscopic bubbles circulated through the bloodstream as a contrast agent to measure the reflection of high-frequency acoustic waves passing through the body.

UCI-led study identifies sex-specific circuits of muscle signaling to other tissues

A new University of California, Irvine-led study identifies sex-specific circuits of muscle signaling to other tissues and that the organs and processes muscle impacts are markedly different between males and females.

Scientists discover a new role for protein complex at the center of Bardet-Biedl syndrome

Scientists have identified a new role for a protein complex at the center of a human genetic disorder called Bardet-Biedl syndrome, or BBS, for which there is currently no cure.

Scientists identify core factors that may put Long QT patients at higher risk of sudden cardiac death

Less than 1 percent of the population has been diagnosed with Long QT syndrome – a rare heart condition that can cause chaotic, sometimes fatal, heart rhythms.

Discovery of new prostate cancer subtype opens the door to development of therapies

Researchers at Weill Cornell Medicine and Memorial Sloan Kettering Cancer Center have identified a previously unrecognized form of hormone therapy-resistant prostate cancer, as well as a set of molecules that drive its growth.

Gut bacteria can reduce the effectiveness of certain blood pressure drugs

A new study from The University of Toledo College of Medicine and Life Sciences has shown gut bacteria can reduce the effectiveness of certain blood pressure drugs.

Researchers identify the genetic causes of three mitochondrial diseases using new approach

When something goes wrong in mitochondria, the tiny organelles that power cells, it can cause a bewildering variety of symptoms such as poor growth, fatigue and weakness, seizures, developmental and cognitive disabilities, and vision problems.

Study brings precision medicine closer to reality for diffuse large B cell lymphoma

DNA mutations are essential to the rapid development of an array of antibody-producing immune cells called B cells that collectively can recognize a vast number of specific targets.

New imaging approach helps scientists build a complete picture of brain networks

Researchers at the Francis Crick Institute have developed an imaging technique to capture information about the structure and function of brain tissue at subcellular level – a few billionth of a metre, while also capturing information about the surrounding environment.
