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.
Postpartum women in bad romantic relationships are not only more likely to suffer symptoms of depression, they are also at greater long-term risk of illness or death, according to new research from Rice University, Ohio State University and the University of California, Irvine.
Researchers at the 23andMe COVID-19 Team, who help search for genetic links associated with the severity of COVID-19, found that the genes UGT2A1 and UGT2A2 may be associated with the loss of smell in those infected with SARS-CoV-2.
Simulators have long been used for training surgeons and surgical teams, but traditional simulator platforms typically have a built-in limitation: they often simulate one or a limited number of conditions that require performance of isolated tasks, such as placing an intravenous catheter, instead of simulating and providing opportunities for feedback on the performance of multiple interventions that a trauma victim may require at the same time.
A new study analyzing the association between an individual's genetics (genotype) and their observable characteristics resulting from the interaction of genetics and the environment (phenotype), contributes new knowledge to the understanding of human complex traits and diseases.
The brain is often likened to a computer: its hardware - neurons organized in complex circuits, its software - a plethora of codes that govern the neurons' behavior.
An interesting new study by researchers at the University of Portsmouth, UK, describes the use of a mathematical method to sequence genomes based on information theory. The method offers an alternative to clinical techniques, allowing mutations to be detected and possibly even predicted. In this way, it opens new research opportunities in bioinformatics and genetics.
Waking up just one hour earlier could reduce a person's risk of major depression by 23%, suggests a sweeping new genetic study published May 26 in the journal JAMA Psychiatry.
Researchers at the University of Illinois Chicago are a step closer to discovering why it is so difficult for people to withdraw from some antidepressant medications.
About 12,000 bacteria and viruses collected in a sampling from public transit systems and hospitals around the world from 2015 to 2017 had never before been identified, according to a study by the International MetaSUB Consortium, a global effort at tracking microbes that is led by Weill Cornell Medicine investigators.
In a new study published online in spring 2021 and in the July issue of the journal Contraception, University of Chicago Medicine investigators and colleagues interviewed primary care providers in Illinois about their interest in providing medication abortion care and found that lifting FDA restrictions on mifepristone to allow pharmacy dispensing could normalize medication abortion, facilitate its use in primary care facilities, and address disparities in reproductive health access.
Skeletal muscle is the largest organ in the body that accounts for 30 to 40% of body weight and is responsible for multiple functions such as energy metabolism and heat production.
The biological clock is present in almost all cells of an organism. As more and more evidence emerges that clocks in certain organs could be out of sync, there is a need to investigate and reset these clocks locally.
A team of scientists from Loyola University Chicago's Stritch School of Medicine have discovered a critical component for renewing the heart's molecular motor, which breaks down in heart failure.
A new multi-institution study led by a team of researchers at the David Geffen School of Medicine demonstrated that blocking a protein called ABCB10 in liver cells protects against high blood sugar and fatty liver disease in obese mice.
In the study published in the journal EClinical Medicine, a dose of 1000 mg of DHA may reduce early preterm births significantly compared to 200 mg as found in some prenatal supplements.
Scientists have successfully treated flies displaying behavioral problems linked to newly discovered schizophrenia-associated genes in humans, using common anti-psychotics.
Protein intake is more important than protein source if the goal is to gain muscle strength and mass.
A new analysis of the effects of SARS-CoV-2, the virus causing the current pandemic, on the human body has provided novel insights into the nature of resilience and how we deal with stressful situations.
Dozens of commonly used drugs, including antibiotics, antinausea and anticancer medications, have a potential side effect of lengthening the electrical event that triggers contraction, creating an irregular heartbeat, or cardiac arrhythmia called acquired Long QT syndrome.
Scientists are rapidly gathering evidence that variants of gut microbiomes, the collections of bacteria and other microbes in our digestive systems, may play harmful roles in diabetes and other diseases.
