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.
Understanding the effects of specific mutations in gene regulatory regions - the sections of DNA and RNA that turn genes on and off - is important to unraveling how the genome works, as well as normal development and disease.
University of Maryland School of Medicine (UMSOM) researchers have shown that psilocybin—the active chemical in “magic mushrooms”— still works its antidepressant-like actions, at least in mice, even when the psychedelic experience is blocked.
Using laboratory-grown roundworms as well as human and mouse eye tissue, University of Maryland School of Medicine (UMSOM) researchers have identified a new potential mechanism for age-related macular degeneration - the leading cause of blindness among older adults.
Liver disease, from metabolic and bacterial causes, is a growing concern. What connects these dots? The gut, or more specifically, bacteria in the gut.
The plasticizers contained in many everyday objects can impair important brain functions in humans. Biologists from the University of Bayreuth warn of this danger in an article in Communications Biology.
Smoking cannabis when you're young may increase your risk of developing heart disease later, according to a recent University of Guelph study.
The Sapien Labs' Human Brain Diversity Project today released an academic paper demonstrating key relationships between stimulus environment and human brain physiology.
Curing cancer has been the dream of countless doctors and researchers over the decades. Yet some types of cancer, whether because they affect relatively few people or lack influential advocates, receive less attention and funding than others.
Ion channels play an indispensable role in cellular physiology, and understanding the physical features that affect ion channel functions is a matter of considerable interest to biologists.
Scientists worldwide are conducting extensive research to understand the nature of the virus, its transmission kinetics, etc. They have found a strong correlation between the ABO blood group and SARS-CoV-2 regarding its morbidity and mortality.
A team led by scientists at the UNC School of Medicine identified a molecule called microRNA-29 as a powerful controller of brain maturation in mammals. Deleting microRNA-29 in mice caused problems very similar to those seen in autism, epilepsy, and other neurodevelopmental conditions.
To effectively perform any daily task, the human brain needs to process information from the outside world using various cognitive functions. This cognitive processing passes through a dense interconnected network of cells whose physiology is specialized.
Race associates with the risk of death from end-stage heart failure. So, identifying the molecular determinants of that risk may help the pursuit of the novel diagnosis and prognosis of heart failure, and its therapy.
Discovering how infections during pregnancy, such as COVID-19 and influenza, can lead to psychiatric illness and developmental disorders in offspring years later, and how to detect, prevent or treat these disorders, is the subject of a $15.7 million grant from the National Institute of Mental Health to the Conte Center at the University of California, Davis.

The National Institute of Arthritis and Musculoskeletal and Skin Diseases has awarded UCI a 5-year, $4.2 million grant to study sporadic inclusion body myositis (sIBM), which affects aging adults causing asymmetric muscle weakness and severe disability. The disease is currently untreatable and poorly understood.
A study at the University of Chicago Medicine found U.S. women experienced increased incidence of health-related socioeconomic risks (HRSRs), such as food insecurity and interpersonal violence, early in the COVID-19 pandemic.
Bacterial DNA methylation occurs at diverse sequence contexts and plays important functional roles in cellular defense and gene regulation. An increasing number of studies have reported that bacterial DNA methylation has important roles affecting clinically relevant phenotypes such as virulence, host colonization, sporulation, biofilm formation, among others.
A novel mechanism has been identified that might explain why a rare mutation is associated with familial Alzheimer's disease in a new study by investigators at the University of Chicago.
