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.

With obesity reaching epidemic levels in some parts of the world, scientists have only begun to understand why it is such a persistent condition. A study in the Journal of Biological Chemistry adds substantially to the story by reporting the discovery of a molecular chain of events in the brains of obese rats that undermined their ability to suppress appetite and to increase calorie burning.

Research reveals vitamin C does not reduce urate levels in gout patients

Research reveals vitamin C does not reduce urate levels in gout patients

Despite previous studies touting its benefit in moderating gout risk, new research reveals that vitamin C, also known ascorbic acid, does not reduce uric acid (urate) levels to a clinically significant degree in patients with established gout. Vitamin C supplementation, alone or in combination with allopurinol, appears to have a weak effect on lowering uric acid levels in gout patients according to the results published in the American College of Rheumatology (ACR) journal, Arthritis & Rheumatism.

Statins, the most widely prescribed drugs worldwide, are often suggested to lower cholesterol and prevent heart disease in individuals with obesity, diabetes and metabolic syndrome, which is a combination of medical disorders including excess body fat and/or high levels of blood pressure, blood sugar and/or cholesterol.

Scientists identify 4 genes in baboons that influence levels of bad cholesterol

Scientists identify 4 genes in baboons that influence levels of bad cholesterol

Scientists at the Texas Biomedical Research Institute in San Antonio have identified four genes in baboons that influence levels of "bad" cholesterol. This discovery could lead to the development of new drugs to reduce the risk of heart disease. [More]
Researchers identify clue to explain the reversible memory loss caused by statins

Researchers identify clue to explain the reversible memory loss caused by statins

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. [More]
Study: Rb plays critical role in maintaining starvation-induced transcriptome

Study: Rb plays critical role in maintaining starvation-induced transcriptome

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. [More]

Most women alter bleeding cycles, find researchers

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.

Nicotine in peppers and tomatoes may provide protective effect against Parkinson's disease

Nicotine in peppers and tomatoes may provide protective effect against Parkinson's disease

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.

Study shows VATS-LCSD can help children with refractory cardiac arrhythmias

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.

ECMO can be used on neonates with severe respiratory failure until lung transplantation, say scientists

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. [More]

Complex network of molecules controls formation and activity of neuronal connections

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. [More]
New gene implicated in Parkinson can delay onset of aging, extend life span

New gene implicated in Parkinson can delay onset of aging, extend life span

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. [More]

Scientists halt tumour development through genetic manipulation of cytoskeleton in fly tissues

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. [More]

Aileron Therapeutics concludes first-in-human study of ALRN-5281 Stapled Peptide drug

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.

Patients with faulty heart valves can benefit from Valve-in-Valve technique

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. [More]

People who gain weight are more conscious of their decision-making, but still give in to temptations

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. [More]

High levels of collagen in breasts are associated with breast cancer metastasis

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. [More]

Exposure to violent video games affects teens' heart rate responses

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.
