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 risk factors for unplanned readmissions following esophageal resection

Researchers identify risk factors for unplanned readmissions following esophageal resection

Esophagectomy is a major surgical procedure associated with significant complications with up to 1 in 5 patients readmitted following hospital discharge. These unplanned readmissions are an important problem as they negatively impact patient care and, in the future, may have implications for reimbursement through the Hospital Readmissions Reduction program.

Exercise may help reduce toxicity caused by glutamate build-up in the brain

Exercise may help reduce toxicity caused by glutamate build-up in the brain

In a new study published today in Applied Physiology, Nutrition, and Metabolism, scientists from the University of Guelph have found that exercise has the potential to decrease toxic build-up in the brain, reducing the severity of brain disorders such as Huntington's disease. [More]
RDAVR system improves survival of patients with severe aortic stenosis

RDAVR system improves survival of patients with severe aortic stenosis

When replacing a defective aortic valve with a new one, restoring function is the first priority. However, variables such as durability, length of surgery, duration of heart stoppage, size of the surgical incision, postoperative pain, and complications are other important considerations. [More]
Exercise plays significant role in combating obesity

Exercise plays significant role in combating obesity

Two factors—metabolism and gut microbes - have been credited by researchers as key players in the fight against obesity. [More]
Single breath-hold for more than five minutes could make targeted radiotherapy feasible

Single breath-hold for more than five minutes could make targeted radiotherapy feasible

Researchers at the University of Birmingham working with clinical teams at University Hospitals Birmingham NHS Foundation Trust have successfully shown for the first time that breast cancer patients can be trained to achieve single prolonged breath holds of over five minutes, opening the door for targeted radiotherapy to be administered with just one dose in each daily session.

Chronic alcohol exposure could negatively impact pancreas' ability to absorb vitamin C

Chronic alcohol exposure could negatively impact pancreas' ability to absorb vitamin C

Chronic exposure to alcohol interferes with the pancreas' ability to absorb vitamin C, potentially predisposing the body to pancreatitis and other pancreatic diseases, a new study in the American Journal of Physiology—Cell Physiology reports. [More]
Could oral supplements affect teenage behavior? An interview with Prof. Stein and Dr Tammam

Could oral supplements affect teenage behavior? An interview with Prof. Stein and Dr Tammam

We wanted to see whether supplementing the diet of disadvantaged adolescents with the omega 3 polyunsaturated acids, EPA & DHA, vitamins and minerals over a school term might improve their antisocial behaviour, which usually gets worse during a term. [More]
Human gut model HuMiX represents actual conditions, processes that occur within intestines

Human gut model HuMiX represents actual conditions, processes that occur within intestines

One of the most complex human organs is the digestive tract: Here, the body comes into contact with all manner of diet-derived compounds and with countless bacteria. [More]
New portable device with hand-held probe could help reduce unnecessary thyroid cancer surgery

New portable device with hand-held probe could help reduce unnecessary thyroid cancer surgery

A team of experts from around Europe has come together to develop a portable device with a hand-held probe that will dramatically reduce invasive diagnostic and therapeutic procedures in the treatment of thyroid nodules, saving approximately €450 million Euros every year. [More]
Simultaneous DNA, RNA and protein analysis to enhance cancer immunology studies: an interview with Dr Joseph Beechem

Simultaneous DNA, RNA and protein analysis to enhance cancer immunology studies: an interview with Dr Joseph Beechem

Cancer immunology is all about how your immune cells are going to fight and kill your tumor cells. If you look at the pure genetic code of a T-cell that's going to kill your tumor compared to the same cell that has been “put-to-sleep” (by the tumor), the pure genetic DNA content of those two cells are identical.

LaVision BioTec, developers of advanced microscopy solutions for the life sciences, will demonstrate their latest light sheet microscope, the UltraMicroscope II at the forthcoming analytica 2016 meeting in Munich. [More]
Researchers identify new molecular targets for recovering motor function in men afflicted with SBMA

Researchers identify new molecular targets for recovering motor function in men afflicted with SBMA

Michigan State University researchers used an old-fashioned neurobiology technique to explore new avenues for treatments to reverse a late-onset neurodegenerative disease that robs men of the capacity to walk, run, chew and swallow. [More]
High levels of exercise from young age can benefit patients with cerebral palsy

High levels of exercise from young age can benefit patients with cerebral palsy

For highly trained Paralympic athletes with cerebral palsy (CP), bone mineral density and other measures of body composition are similar to those of able-bodied adults of similar age, reports a study in the American Journal of Physical Medicine & Rehabilitation, the official journal of the Association of Academic Physiatrists.

Key protein involved in mitosis helps prevent abnormal distribution of chromosomes

Key protein involved in mitosis helps prevent abnormal distribution of chromosomes

A tension-sensitive "fail safe" protein helps make sure that when our cells divide the two resulting cells inherit the normal number of chromosomes, researchers from the University of Washington and the Fred Hutchinson Cancer Research Center report today, May 5, in the journal Cell. [More]
Cancerous lung tumors can alter metabolism by hijacking circadian mechanisms

Cancerous lung tumors can alter metabolism by hijacking circadian mechanisms

University of California, Irvine scientists who study how circadian rhythms - our own body clocks - control liver function have discovered that cancerous lung tumors can hijack this process and profoundly alter metabolism. [More]
Drinking tart Montmorency cherry juice can reduce early signs of hypertension

Drinking tart Montmorency cherry juice can reduce early signs of hypertension

Drinking tart Montmorency cherry juice significantly reduces high blood pressure at a level comparable to that achieved by medication, according to new research from Northumbria University, Newcastle. [More]
Development of atherosclerosis can increase osteoporosis risk

Development of atherosclerosis can increase osteoporosis risk

Patients with atherosclerosis—the buildup of cholesterol and fat in arteries—are at a higher risk of osteoporosis. A new study published in the American Journal of Physiology—Endocrinology and Metabolism shows how the development of atherosclerosis encourages the loss of bone density. [More]
Depressed moms not physiologically 'in sync' with their children

Depressed moms not physiologically 'in sync' with their children

Mothers with a history of depression are not physiologically "in sync" with their kids, according to a new study from Binghamton University. While researchers have known for a while that depression is associated with interpersonal problems with others, this is the first study to examine whether this is also evident physiologically. [More]
