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.
Researchers discover that a specialized part of the chromosomes, essential for a correct cell division, is smaller and weaker in stem cells, when compared to the ones of differentiated cells.
In the nearly two centuries since German physician Carl Wunderlich established 98.6°F as the standard "normal" body temperature, it has been used by parents and doctors alike as the measure by which fevers -- and often the severity of illness -- have been assessed.
A new observational study by Swedish researchers shows a significant decline in death rates among hospitalized patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Their study titled, "Decline in mortality among hospitalized covid-19 patients in Sweden: a nationwide observational study," was released online as a preprint on the medRxiv* server.
Research at Washington State University sheds new light on one molecule that may be used to treat a heart condition that can lead to stroke, heart attack and other forms of heart disease.
A new study from Lawson Health Research Institute, Western University and University of Alberta suggests that COVID-19 affects the human body's blood concentration levels of specific metabolites - small molecules broken down in the human body through the process of metabolism.
A new study by researchers at UC Santa Cruz shows how a genetic mutation throws off the timing of the biological clock, causing a common sleep syndrome called delayed sleep phase disorder.
MicroRNAs (miRNAs) are evolutionarily conserved small noncoding RNAs - bits of genetic code that serve as critical gene regulators in many aspects of biological processes important for human health.
To identify new potential therapeutic targets for SARS-CoV-2, a team of scientists at the New York Genome Center, New York University, and the Icahn School of Medicine at Mount Sinai, performed a genome-scale, loss-of-function CRISPR screen to systematically knockout all genes in the human genome.
University of North Carolina School of Medicine scientists has made a curious discovery about a well-known human protein that helps the immune system fight viral infections.
Research from Saint Louis University finds that high fat or "ketogenic" diets could completely prevent, or even reverse heart failure caused by a metabolic process.
Exposure to higher air pollution levels and greater population density during the early months of life may be associated with an increase in children's body mass index (BMI).
"Wound healing is one of the most complex biological processes," writes Professor Kazumitsu Sugiura and Dr. Kenta Saito from Fujita Health University, Japan, in their article recently published in Nature's Scientific Reports.
Stubbornly, frustratingly, pancreatic cancer has remained resistant to immunotherapies that are revolutionizing the treatment of many types of cancer.
By using a diverse set of transcriptomic SARS-CoV-2 signatures, US researchers put to use their previously developed drug repositioning pipeline to pinpoint potential drug candidates for the treatment of coronavirus disease (COVID-19). The study is currently available on bioRxiv preprint server.
The findings, simultaneously published in the New England Journal of Medicine and presented at the American Society of Nephrology's Kidney Week 2020 conference, show the investigational drug finerenone had tangible renal and cardiovascular benefits for patients with chronic kidney disease and type 2 diabetes.
A new discovery about how the body transports dexamethasone, a drug that can increase the survival chances of patients with severe COVID-19, suggests diabetes and other factors may reduce its potentially lifesaving effectiveness.
The Alzheimer's Biomarkers Consortium - Down Syndrome, a multi-institution research team, co-led by members from the University of California, Irvine, has been awarded an unprecedented five-year, $109 million grant by the National Institutes of Health, to expand research on the biomarkers of Alzheimer's disease in adults with Down syndrome.
A team of medics from RUDN University conducted an experiment on rats and confirmed that surgeries in the nasal cavity can cause behavioral changes, namely, make the animals timider.
Brain cell dysfunction in low oxygen is, surprisingly, caused by the very same responder system that is intended to be protective, according to a new published study by a team of researchers at the Case Western Reserve University School of Medicine.
As researchers and medical professionals work to develop new treatments for cancer, they face a variety of challenges.
