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.
George Washington University (GW) researcher David Mendelowitz, Ph.D., was recently published in the Journal of Neuroscience for his research on how heart rate increases in response to alertness in the brain.
Researchers from The Netherlands found that snacking on high-fat and high-sugar foods was independently associated with abdominal fat and fatty liver (hepatic steatosis).
Researchers find link between phosphate rich foods and an enzyme linked to cardiovascular disease. The findings also link phosphates to renal disease.
The latest organ-on-a-chip from Harvard's Wyss Institute for Biologically Inspired Engineering reproduces the structure, functions and cellular make-up of bone marrow, a complex tissue that until now could only be studied intact in living animals, Institute researchers report in the May 4, 2014, online issue of Nature Methods.
The American Gastroenterological Association (AGA) has announced the recipients of its annual recognition awards, given in honor of outstanding contributions and achievements in gastroenterology.
Nikki Posnack, Ph.D., a post-doctoral pharmacology and physiology researcher at the George Washington University School of Medicine and Health Sciences (SMHS), received a $209,926 grant from the National Institute of Environmental Health Sciences to study plastics and their potential human health risks, particularly in the cardiovascular system.
Environmental factors are more important than previously thought in understanding the causes of autism, and equally as important as genes, according to the largest study to date to look at how autism runs in families.
An oral capsule that vibrates as it moves through the digestive tract has shown notable promise as a non-pharmacological treatment for constipation, according to new research presented today at Digestive Disease Week- (DDW).
A team of researchers from Sanford-Burnham Medical Research Institute (Sanford-Burnham) and SUNY Downstate Medical Center (SUNY Downstate) has found that deficiencies in hyaluronan, also known as hyaluronic acid or HA, can lead to spontaneous epileptic seizures.
Quality of life (QOL) is rarely reported in surgical publications, yet it can be an important metric that can be of use to physicians and patients when making treatment decisions.
Researchers at the University of Louisville School of Medicine are using breath analysis to detect the presence of lung cancer. Preliminary data indicate that this promising noninvasive tool offers the sensitivity of PET scanning, and has almost twice the specificity of PET for distinguishing patients with benign lung disease from those with early stage cancer.
A new study has found that children and adolescents with attention deficit hyperactivity disorder (ADHD) have disrupted connections between different areas of the brain that are evident on resting-state functional magnetic resonance imaging (rfMRI).
In healthy individuals, the amount of glucose, or sugar, in the blood increases after eating. When glucose increases, levels of insulin increase to carry the glucose to the rest of the body. Previous research has shown that extreme increases in glucose and insulin in the blood can lead to poor glucose control and increase an individual's risk of developing diabetes over time. Now, a University of Missouri researcher has found that when women consumed high-protein breakfasts, they maintained better glucose and insulin control than they did with lower-protein or no-protein meals.
A new study out of Western University (London, Canada) illustrates the need for a lot more education around pharmacogenetics (PGx) -the study of how a patient's genes can affect drug reaction and dosage.
Monarch Medical Technologies, the pioneer and leader in mitigating risk associated with drugs and processes of concern in hospitalized patients, today announced the U.S. Food and Drug Administration clearance of its new glucose management solution, EndoTool IV.
Biologists have discovered how an outer shield over T-type channels change the electrochemical signaling of heart and brain cells. Understanding how these shields work will help researchers eventually develop a new class of drugs for treating epilepsy, cardiovascular disease and cancer.
Large sections of the genome that were once referred to as "junk" DNA have been linked to human heart failure, according to research from Washington University School of Medicine in St. Louis.
A new study published online in the Journal of Applied Physiology shows additional benefits of consuming a blend of soy and dairy proteins after resistance exercise for building muscle mass.
Reactive oxygen species are important intracellular signaling molecules, but their mode of action is complex: In low concentrations they regulate key aspects of cellular function and behavior, while at high concentrations they can cause "oxidative stress", which damages organelles, membranes and DNA.
The greater prevalence of asthma, allergies and other chronic inflammatory disorders among people of lower socioeconomic status might be due in part to their reduced exposure to the microbes that thrive in rural environments, according to a new scientific paper.
