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.
The U.S. Food and Drug Administration and physicians continue to document that some patients experience fuzzy thinking and memory loss while taking statins, a class of global top-selling cholesterol-lowering drugs.
A particular tumor suppressor gene that fights cancer cells does more than clamp down on unabated cell division -- the hallmark of the disease -- it also can help make cells more fit by allowing them to fend off stress, says a University of Colorado Boulder study.
A surprisingly large number of women 18 or older choose to delay or skip monthly menstruation by deviating from the instructions of birth-control pills and other hormonal contraceptives, a team of University of Oregon researchers and others found in a study of female students at the university.
New research reveals that Solanaceae-a flowering plant family with some species producing foods that are edible sources of nicotine-may provide a protective effect against Parkinson's disease. The study appearing today in Annals of Neurology, a journal of the American Neurological Association and Child Neurology Society, suggests that eating foods that contain even a small amount of nicotine, such as peppers and tomatoes, may reduce risk of developing Parkinson's.
Inherited ventricular arrhythmias are an important cause of morbidity and sudden cardiac death in children who have structurally normal hearts. Despite conventional medical therapy, some of these children remain symptomatic with recurrent life-threatening arrhythmias, syncope, or frequent discharges from implantable cardioverter defibrillators.
Adults with end-stage respiratory failure and pulmonary hypertension requiring ECMO (extracorporeal membrane oxygenation) have been "bridged" toward lung transplantation with novel lung assist devices such as the Novalung.
Environment moulds behaviour - and not just that of people in society, but also at the microscopic level. This is because, for their function, neurons are dependent on the cell environment, the so-termed extracellular matrix.
UCLA life scientists have identified a gene previously implicated in Parkinson's disease that can delay the onset of aging and extend the healthy life span of fruit flies. The research, they say, could have important implications for aging and disease in humans.
Cancer is a complex disease, in which cells undergo a series of alterations, including changes in their architecture; an increase in their ability to divide, to survive and to invade new tissues or metastasis.
Aileron Therapeutics, Inc. today announced the completion of the first-in-human study of its lead Stapled Peptide drug, ALRN-5281, a proprietary, long-acting growth-hormone-releasing hormone (GHRH) agonist for treating orphan endocrine disorders, including adult growth hormone (GH) deficiency and human immunodeficiency virus (HIV) lipodystrophy, as well as broader patient populations involving a wide variety of metabolic/endocrine diseases.
When a biologic aortic valve prosthesis fails, the patient often faces a high risk valve replacement through repeat open heart surgery. A new technique, known as Valve-in-Valve, uses minimally invasive techniques to introduce a collapsible aortic heart valve into the damaged valve in order to restore function.
People who gain weight are more likely to give in to temptations but also are more thoughtful about their actions, according to a new study published in Psychological Science, a journal of the Association for Psychological Science.
Researchers at Washington University School of Medicine in St. Louis have discovered why breast cancer patients with dense breasts are more likely than others to develop aggressive tumors that spread.
Teenagers who are highly exposed to violent video games—three or more hours per day—show blunted physical and psychological responses to playing a violent game, reports a study in the May issue of Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society.
Teenagers with high blood pressure appear to have better psychological adjustment and enjoy higher quality of life than those with normal blood pressure, suggests a study in the May issue of Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society.
A major international study involving a Simon Fraser University scientist has found that sequence differences in a gene crucial to the maintenance of our chromosomes' integrity predispose us to certain cancers.
In a study using mice, researchers from the University of North Carolina at Chapel Hill found that a hormone, adrenomedullin, plays a crucial role in preventing the pregnancy complication preeclampsia.
A small survey of U.S. obstetrics and gynecology residents finds that fewer than one in five receives formal training in menopause medicine, and that seven in 10 would like to receive it.
Long after a hangover, a night of bad decisions might take a bigger toll on the body than previously understood. Described in the current issue of Alcoholism: Clinical & Experimental Research, a study at the University of Missouri has revealed a unique connection between binge drinking and the risk for developing alcoholic liver disease and a variety of other health problems.
Archimedes, Inc., a healthcare modeling and analytics company, announced today that it has begun collaborating with the United States Department of Health and Human Services and Centers for Medicare & Medicaid Services to provide unprecedented access to synthetic CMS claims data.
