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 identify crucial innate immunity role for gene linked to ARC syndrome in children

UT Southwestern Medical Center researchers have found an important innate immunity role for a gene linked to a rare, fatal syndrome in children. Their study has implications for a much more common disease: tuberculosis.

Research findings elucidate how neurons process, represent touch in rat and the human brain

When reaching into a pocket or purse, it is easy to use the sense of touch to distinguish keys from loose change. Our brains seamlessly integrate the tactile, sensory cues from our fingers with hand movements to perceive the different objects.

Scientists use animal model to gain better understanding of cocaine addiction

Scientists at Wake Forest Baptist Medical Center are one step closer to understanding what causes cocaine to be so addictive. The research findings are published in the current issue of the Journal of Neuroscience.

Paternal over-nutrition may lead to generational obesity and metabolic dysfunction

Paternal intake of a high-fat diet (HFD) can cause genetic changes that lead to generational obesity and metabolic dysfunction—including body weight and fat mass increases and changes in blood pressure, triglyceride levels and fat metabolism—in mice, according to Japanese researchers at Okayama University.

Overcoming gene silencing barriers to target neurological conditions: an interview with Dr Errol de Souza

Many gene mutations that cause neurological disorders have been identified. For example, in a rare neurological disorder such as Huntington’s disease, an autosomal dominant mutation through expansion of CAG (cytosine-adenine-guanine) triplet repeats in the gene coding for the Huntingtin protein results in abnormal protein production.

Researchers identify reason why antidepressants take so long to work

An episode of major depression can be crippling, impairing the ability to sleep, work, or eat. In severe cases, the mood disorder can lead to suicide. But the drugs available to treat depression, which can affect one in six Americans in their lifetime, can take weeks or even months to start working.

Changes in the brain's pleasure center may decrease physical activity in postmenopausal women

As women enter menopause, their levels of physical activity decrease; for years scientists were unable to determine why.

New research elucidates details about architecture of synaptic transmission

For more than a century, neuroscientists have known that nerve cells talk to one another across the small gaps between them, a process known as synaptic transmission.

Levels of peptide hormone adropin linked to carbohydrate intake

In research featured in the August edition of Obesity, Saint Louis University investigator Andrew Butler, Ph.D., and his team report that levels of the peptide hormone adropin vary based on carbohydrate consumption and appear to be linked to lipid metabolism.

World Scientific's new book captures novel view of human voice from perspective of voice production

Most recently, scientists dealing with the human voice have taken a novel view of the human voice from the perspective of voice production. The vitality of this new science is evidenced by five issued US patents.

Single drink of nutritional ketone can alter metabolism to improve performance of cyclists

A drink developed for soldiers to generate energy from ketones rather than carbs or fat allowed highly trained cyclists to add up to 400 meters of distance to their workouts, a UK-led study reports July 27 in Cell Metabolism.

Penn study sheds new light on biology of fatty liver disease

A new appreciation for the interplay between two cell nucleus proteins that lead both intertwined and separate lives is helping researchers better understand fatty liver disease, according to a new study by researchers at the Perelman School of Medicine at the University of Pennsylvania.

Large study of familial ALS finds new gene variant present in 3% of all patients with disease

Variations in a gene with multiple functions in neurons are present in approximately 3 percent of all cases of ALS in North American and European populations, both sporadic and familial, making it one of the most common genetic causes of the disease, according to a paper published in Nature Genetics.

Sleep researchers call for new diagnostic criteria to treat OSA in pregnant women

Recent studies reveal that approximately one quarter of pregnant women may suffer from Obstructive Sleep Apnea (OSA), the recurrent cessation or limitation of normal breathing during sleep.

Salmonella protein can reduce drug resistant molecule found in cancer cells

A surprising result in an experiment on Salmonella bacteria has led to a discovery that may make drug resistant cancer cells more treatable by conventional chemotherapies.

Rat study finds maternal intake of oxidised fish oil causes high newborn mortality

Nearly 30 percent of newborn pups born to pregnant rats fed highly oxidized ("off") fish oil died within two days after birth a new study by researchers at the Liggins Institute at the University of Auckland in New Zealand finds.

Long-term antibiotic treatment slows progression of Alzheimer's disease through changes in gut bacteria

Long-term treatment with broad spectrum antibiotics decreased levels of amyloid plaques, a hallmark of Alzheimer's disease, and activated inflammatory microglial cells in the brains of mice in a new study by neuroscientists from the University of Chicago.

Noninvasive brain stimulation may curb cravings for appetitive foods

Available research suggests that noninvasive stimulation of a specific brain area can reduce food cravings—particularly for high-calorie, "appetitive" foods, according to a review in the Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society. The journal is published by Wolters Kluwer.
