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.
Repeatedly losing and regaining weight may lead to improved insulin levels and lower body fat percentages in the long term, even during weight regain phases.
Researchers from Graduate School of Medicine, Nagoya University, Hokkaido University Graduate School of Medicine and Gunma University Graduate School of Medicine have collaborated to uncover the role of GABA-ergic neurons or the inhibitory neurons in the functioning of the central circadian clock of the body.
When you experience severe pain, like breaking or shattering a bone, the pain isn't just felt at the sight of the injury.
Much research has pointed to how an unhealthy diet correlates to obesity, but has not explored how diet can bring about neurological changes in the brain.
A fundamental question in nerve biology brings to mind a race car at the starting line: The engine is revving, but the brake is on. The system is ready to go, but under tight control.
Biosero, Inc. has formed a strategic advisory board made up of four members who will contribute to Biosero’s mission to provide automation software solutions that enable people and technology to make complex decisions in less time, using more data.
The research team led by Dr. Daisuke Ono and Prof. Akihiro Yamanaka of the Graduate School of Medicine, Nagoya University, collaborating with Prof. Ken-ichi Honma and Prof. Sato Honma of Hokkaido University Graduate School of Medicine, and Prof. Yuchio Yanagawa of Gunma University Graduate School of Medicine revealed that inhibitory neurons (GABAergic neurons) of the central circadian clock in the suprachiasmatic nucleus (SCN) refine circadian output rhythms.
Beta cells in the pancreas produce insulin. Their death is a key feature of Type 1 diabetes, and that loss starts long before diagnosis. However, there has been no straightforward way to measure that early loss.
A new study in mice led by UCLA biologists strongly suggests that serotonin and drugs that target serotonin, such as anti-depressants, can have a major effect on the gut's microbiota -- the 100 trillion or so bacteria and other microbes that live in the human body's intestines.
Frostbite is an injury which usually affects the extremities, such as fingers and toes, and has the potential of causing irreversible tissue loss.
A research collaboration based in Japan has found a new pathological mediator of amyotrophic lateral sclerosis, which could have further implications for understanding the molecular breakdown that gives rise to the neurodegenerative disease that affects nearly half a million people around the world.
Hypertension or high blood pressure is a major killer worldwide, accounting for much death and disease burden due to cardiovascular disease. Multiple factors influence the risk for this condition, some acting in adulthood but some operating from birth or even earlier.
A study conducted by researchers from the University of Granada recommends spending more time standing to increase energy expenditure and combat the negative health effects of a sedentary lifestyle.
A new study has shown that exercise can restore key tissues and reduce the risk of metabolic disorders such as type 2 diabetes.
Adolescents exposed to higher levels of fine-particle air pollutants have heightened autonomic nervous system reactions to social stress, reports a study in Psychosomatic Medicine: Journal of Biobehavioral Medicine, the official journal of the American Psychosomatic Society.
New findings on the serious adverse outcomes associated with non-medical use (NMU) of prescription amphetamines for attention deficit hyperactivity disorder were recently published in the September 2019 issue of the Journal of Attention Disorders.
Longer NFL careers and certain playing positions appear to each spell greater long-term risk for serious cognitive problems such as confusion, memory deficits, depression and anxiety in former football players, according to a new report published Aug. 30 in The American Journal of Sports Medicine.
Research published in Cell on 29th August by the groups of Filipe Cabreiro from the MRC London Institute of Medical Sciences and Imperial College and Christoph Kaleta from Kiel University in Germany has demonstrated that diet can alter the effectiveness of a type-2 diabetes drug via its action on gut bacteria.
The dangers of ultraviolet radiation exposure, which most often comes from the sun, are well-known. Speaking at The Physiological Society's Extreme Environmental Physiology conference next week, W. Larry Kenney, Penn State University, will discuss how broad its effects can be, from premature aging to cancer, and how this can be influenced by different skin tones and the use of sunscreen.
Older people who have never taken part in sustained exercise programmes have the same ability to build muscle mass as highly trained master athletes of a similar age, according to new research at the University of Birmingham.
