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.

Targeting brain’s waste removal system may help combat cognitive decline

As aging bodies decline, the brain loses the ability to cleanse itself of waste, a scenario that scientists think could be contributing to neurodegenerative conditions such as Alzheimer's disease and Parkinson's disease, among others.

Study offers new insights into the harmful effects of sugar-sweetened beverages on human health

Researchers at the Advanced Research Unit on Metabolism, Development & Aging (ARUMDA), in the Tata Institute of Fundamental Research (TIFR, Mumbai and TIFR Hyderabad), have unveiled a comprehensive understanding of the harmful effects of sugar-sweetened beverages (SSBs) on human health, using a preclinical mouse model that closely mimics human consumption patterns.

High-fat diet impairs neutrophil function in obesity

A new study in The Journal of Immunology reveals how a high-fat diet may impair the immune system's ability to respond to infection by impacting the function of neutrophils, one of the first immune cells to respond to bacteria or viruses.

Cell map offers insights into endometrial dysfunction in women with PCOS

Women with polycystic ovary syndrome (PCOS) find it harder to get pregnant, have more frequent miscarriages and have a higher risk of developing endometrial cancer.

Small intestine grows in response to pregnancy in mice

Researchers at the Francis Crick Institute have found that the small intestine grows in response to pregnancy in mice. This partially irreversible change may help mice support a pregnancy and prepare for a second.

Australian scientists redefine dietary fiber classification for better health benefits

Australian food scientists have reclassified dietary fibers – beyond just soluble and insoluble – to better guide nutritional decisions and drive targeted health food products.

Testing a novel approach to restore normal heart function in Myotonic Dystrophy Type 1

Myotonic Dystrophy Type 1 (DM1) is the most common adult-onset form of muscular dystrophy and a condition that severely affects multiple organs including skeletal muscle, heart, brain and the gastrointestinal tract.

New discovery unravels mystery behind overactive immune responses

Autoimmune diseases, which are estimated to affect more than 15 million people in the U.S., occur when the body responds to immune-system false alarms, and infection-fighting first responders are sent out to attack threats that aren't there.

Scientists say NIH officials told them to scrub mRNA references on grants

National Institutes of Health officials have urged scientists to remove all references to mRNA vaccine technology from their grant applications, two researchers said, in a move that signaled the agency might abandon a promising field of medical research.

Breakthrough peptide inhibitor effective against multiple SARS-CoV-2 variants

SARS-CoV-2, the virus responsible for COVID-19, infects cells by binding its spike protein to angiotensin-converting enzyme 2 (ACE2) receptors.

Bioenergetic age could predict Alzheimer's disease risk

A person's "bioenergetic age"-or how youthfully their cells generate energy-might be a key indicator of whether they're at risk of developing Alzheimer's disease, new research from Weill Cornell Medicine shows.

New method enhances precision in monitoring brain activity during deep brain stimulation

Mayo Clinic researchers have found a new way to more precisely detect and monitor brain cell activity during deep brain stimulation, a common treatment for movement disorders such as Parkinson's disease and tremor.

Promising drug enhances motor recovery after spinal cord injury

Spinal cord injury (SCI)-a condition that leads to partial or complete paralysis-has a profound impact on millions of individuals globally.

Diterpenes show promise in regenerating neurons after brain injury

Researchers from the University of Seville and the University of Cadiz, coordinated by the professors of Physiology Pedro Núñez-Abades and Carmen Castro, have demonstrated that the use of diterpenes facilitates repopulation with new neurons in brain regions damaged by traumatic injuries.

3D imaging sheds light on how nerves and blood vessels in the skull decline with age

As the body ages, bones undergo changes that can hinder their ability to regenerate and heal. While previous studies have concentrated on the structural shifts in bone tissue itself, the role of nerves and blood vessels—critical players in bone health—has remained relatively unexplored.

Regulating cell acidity could transform autoimmune disease treatments

What if treating autoimmune diseases was as simple as regulating the acidity levels of parts of patients' cells? Genetic screening may have unlocked a path for treating the severe inflammation associated with many immune diseases by regulating one protein's role in helping another protein control cell acidity, according to new research published in Cell by a team from the Perelman School of Medicine at the University of Pennsylvania.

Gender gaps in peripheral vascular disease impact diagnosis and treatment

The disparities between men and women in prevalence, risk factors and symptoms of peripheral vascular disease (PVD) have a profound impact on prevention, diagnosis, treatment and outcomes for women, according to a new American Heart Association scientific statement published today in the Association's flagship, peer-reviewed journal Circulation.

Study highlights the role of ELF4 as a key transcription factor in development, immunity, and oncology

ELF4, a transcription factor belonging to the ETS family, has emerged as a pivotal regulator in cell differentiation, immune system function, and cancer progression. This newly published review underscores its molecular complexity and clinical significance, shedding light on its dual role in tumor suppression and oncogenesis.
