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.
Tuberous Sclerosis Complex (TSC) affects between one and two of every 10,000 new-born babies. This genetic disease leads to the formation of benign tumors which can massively impair the proper functioning of vital organs such as the kidneys, the liver and the brain.
Lysophospholipids are phospholipids that have just one fatty acid chain, and in recent years, the role of lysophospholipids in physiology and pathophysiology has attracted attention.
Admit it: Daily commutes - those stops, the starts, all that stress - gets on your last nerve.
Thus, the need to stratify the risk of severe or critical disease in patients presenting with SARS-CoV-2 infection remains a crying necessity. A new preprint research paper posted to the medRxiv server discusses the relationship between severe disease and pre-existing susceptibility to clots and other diseases of the cardiovascular system.
Gero has developed and validated GeroSense AI to track biological age and resilience via smartphone sensor data. The performance of the new health and aging markers have been recently reported in a paper in Aging US.
Many have assumed that the rates of major abdominal surgeries in adults over 65 is increasing over time as the U.S. population ages and as new technology renders surgical procedures safer for older adults.
A neurologic pathway by which non-damaging but high frequency brain impact blunts normal brain function and causes long-term problems with learning and memory has been identified.
Spurred by unproven assumptions that vaping is safer than smoking cigarettes, a team at West Virginia University is conducting a three-year study on the effects of vaping during pregnancy.
A gene called GAS2 plays a key role in normal hearing, and its absence causes severe hearing loss, according to a study led by researchers in the Perelman School of Medicine at the University of Pennsylvania.
New research published in Experimental Physiology highlight the possible long term health impacts of COVID-19 on young, relatively healthy adults who were not hospitalized and who only had minor symptoms due to the virus.
It turns out that not all build-ups of tau protein are bad, and a team of researchers from the Perelman School of Medicine at the University of Pennsylvania developed a method to show that.
Magnetic Resonance Imaging (MRI) images are usually meant to be static. But now, researchers from Mātai Medical Research Institute (Mātai), Stevens Institute of Technology, Stanford University, the University of Auckland and other institutions, report on an imaging technique that captures the brain in motion in real time, in 3D and in stunning detail, providing a potential diagnostic tool for detecting difficult-to-spot conditions such as obstructive brain disorders and aneurysms - before they become life threatening.
By discovering a potential new cellular mechanism for migraines, researchers may have also found a new way to treat chronic migraine.
In a recent study, researchers demonstrated a human organ-on-a-chip (Organ Chip) microfluidic model of the lung alveolus (Alveolus Chip) - that recapitulates the human alveolar-capillary interface with an air-liquid interface (ALI) and vascular fluid flow to understand the local triggers in the lung in vitro.
Our kidneys are charged with the extraordinary task of filtering about 53 gallons of fluid a day, a process that depends on podocytes, tiny, highly specialized cells in the cluster of blood vessels in the kidney where waste is filtered that are highly vulnerable to damage.
A new study, published in JCI Insight, looks at how Brd4, a regulator of the innate immune response, influences diet-induced obesity.
Blood may seem like a simple fluid, but its chemistry is complex. When too much potassium, for instance, accumulates in the bloodstream, patients may experience deadly irregular heart rhythms.
Thanks to the so-called deep learning, a subset of artificial intelligence (AI) algorithms inspired by the brain, machines can match human performance in perception and language recognition and even outperform humans in certain tasks. But do these synthetic biologically inspired systems learn in the same way that we do?
A new gene-editing technique can be used to correct mutations in muscle stem cells, paving the way for the first potential cell therapy for genetic muscle disorders.
For many of us, adding salt to a meal is a perfectly normal thing to do. We don't really think about it. But actually, we should. As well as raising our blood pressure, too much salt can severely disrupt the energy balance in immune cells and stop them from working properly.
