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.

Treatment for IBS proves difficult, survey reveals

A new national survey by Health Union of more than 1,000 individuals with Irritable Bowel Syndrome (IBS) reveals that the condition is difficult to diagnose and often even more difficult to treat.

New electric mesh device wraps around the heart to deliver electrical impulses

A research team led by investigators at Beth Israel Deaconess Medical Center and Seoul National University has developed a new electric mesh device that can be wrapped around the heart to deliver electrical impulses and thereby improve cardiac function in experimental models of heart failure, a major public health concern and leading cause of mortality and disability.

Why does appetite loss occur during illness? An interview with Prof. Conti and Prof. Francesconi

Appetite, as a word, come from the Latin appetitus, meaning "desire for.” Therefore, appetite can be defined as a pleasurable sensation or the desire to eat. This sensation is coordinated by several brain areas associated with reward processing such amygdala, hippocampus, ventral pallidum, nucleus accumbens and striatum, and others.

Researchers investigate why N14Y, N14K mutations have distinct effects in KID syndrome patients

A team of New York-based researchers has compared the effects of two disease-causing mutations, potentially explaining why patients with the rare genetic disorder keratitis-ichthyosis-deafness (KID) syndrome can experience different sets of symptoms.

New computer model shows how spleen filters misshapen red blood cells

Researchers, led by Carnegie Mellon University President Subra Suresh and MIT Principal Research Scientist Ming Dao, have created a new computer model that shows how tiny slits in the spleen prevent old, diseased or misshapen red blood cells from re-entering the bloodstream.

Anti-anxiety medication dampens helping behavior in rats

Rats given midazolam, an anti-anxiety medication, were less likely to free trapped companions because the drug lessened their empathy, according to a new study by University of Chicago neuroscientists.

Women more afraid of childbirth than previously thought

Every woman who has ever had a baby shower has had to sit through the gruesome war stories about labor and childbirth.

Study reveals distribution of toxic arsenic in cell nuclei of plants

Toxic arsenic initially accumulates in the nuclei of plants' cells. This has been revealed by an X-ray examination of the aquatic plant rigid hornwort (Ceratophyllum demersum) using DESY's X-ray source PETRA III.

Photodynamic therapy effective in treating porphyrias but can be severely painful, cause inflammation

Severe paleness and photosensitivity are two symptoms of a rare group of hereditary diseases that affect haem, a substance in the blood. While these metabolic disorders - known as the porphyrias - are extremely rare, a similar effect is often deliberately triggered by dermatologists in localised areas during the treatment of pre-cancerous skin lesions and skin cancers.

The future of simulated teaching methods

In healthcare, we have physicians, nurses and paramedics who know the textbook by heart and know exactly what they need to do, but have never experienced the procedure first-hand, or they have no experience responding to adverse events that may occur.

Simple method may help predict type 2 diabetes risk in women with gestational diabetes

An international team of researchers has discovered a simple, accurate new way to predict which women with gestational diabetes will develop type 2 diabetes after delivery.

Long-term suppression of neurotransmitter acetylcholine may lead to dementia-like changes in the brain

A new study from Western University is helping to explain why the long-term use of common anticholinergic drugs used to treat conditions like allergies and overactive bladder lead to an increased risk of developing dementia later in life.

First CRISPR/Cas9 screen helps identify human proteins required for Zika virus replication

Scientists at the University of Massachusetts Medical School have performed the first CRISPR/Cas9 screen to discover human proteins that Zika virus needs for replication.

Composition of microbiota plays significant role in body's ability to accept transplanted tissue

Researchers from the University of Chicago have shown that microbiota—the bacteria, viruses and other microbes living on the skin and in the digestive system—play an important role in the body's ability to accept transplanted skin and other organs.

Researchers identify new myosin kinase that could optimize heart contractions

The heart is the only muscle that contracts and relaxes continuously over a lifetime to pump oxygen-rich blood to the body's organs. Researchers at UT Southwestern Medical Center now have identified a previously unrecognized enzyme that could optimize contraction and lead to new strategies to treat heart failure.

Long-term opioid therapy may not be effective to manage pain in sickle cell disease patients

In a small study looking at pain assessments in adults with sickle cell disease, researchers at Johns Hopkins says overall, those treated long-term with opioids often fared worse in measures of pain, fatigue and curtailed daily activities than those not on long-term opioids.
