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.
Scientists from the School of Medicine at The University of Texas Health Science Center at San Antonio have found a clue as to why muscles weaken with age. In a study published Feb. 5 in The Journal of Neuroscience, they report the first evidence that "set points" in the nervous system are not inalterably determined during development but instead can be reset with age. They observed a change in set point that resulted in significantly diminished motor function in aging fruit flies.
New research shows that children with febrile status epilepticus (FSE) who receive earlier treatment with antiepileptic drugs (AEDs) experience a reduction in the duration of the seizure.
How is living in space like playing in the Super Bowl? Both involve circumstances that cause the body to involuntarily lose water. Astronauts and athletes with low body water can suffer physical performance impairments and can develop symptoms such as headaches, fatigue, muscle cramps, light headedness, disorientation and, in severe cases, loss of consciousness.
Opening up a can of worms is a good way to start hunting for new drugs, recommend researchers from Children's Hospital of Pittsburgh of UPMC and the University of Pittsburgh School of Medicine.
Vitamin C and E supplements may blunt the improvement of muscular endurance - by disrupting cellular adaptions in exercised muscles - suggests a new study published today [3 February] in The Journal of Physiology.
New reseach reveals that women who have a child after experiencing fertility problems are more likely to remain with their partner following infertility evaluations.
A University of Arizona doctoral candidate has shown for the first time that genetic mutations in the titin gene can cause skeletal muscle myopathy, a disease in which muscle fibers do not function properly, resulting in muscle weakness.
Gene related to the proliferation of cancerous cells blocked through molecular technology. A group of researchers from Mexico's General Hospital, Health Secretariat, Medicine Faculty and the Institute of Cellular Physiology of the National Autonomous University of Mexico (UNAM) identified a therapeutic target for cervix cancer: gene CDKN3.
The UNC School of Medicine has awarded the 14th Perl-UNC Neuroscience Prize to Marcus Raichle, MD, a neurologist from Washington University in St. Louis who has made remarkable research findings about the persistent brain activity of our at-rest minds.
NanoLogix Inc. (NNLX), an innovator in the rapid detection, identification and determination of antibiotic resistance and sensitivity of live bacteria, announces that the State of Ohio Department of Economic Development's International Trade Assistance Center (ITAC) based at Youngstown State University (YSU) is providing support to Hubbard Ohio-based NanoLogix Inc. for international distribution of NanoLogix products by Nasaem Al-Jazira, a Saudi Arabian Trading and Distribution Company.
Researchers from New Zealand report that morbidity following liver transplant is highest among obese patients with diabetes, but these risk factors do not influence post-transplant survival.
PerkinElmer Inc., a global leader focused on the health and safety of people and the environment, has announced the launch of the Opera Phenix™, a next-generation, confocal, high-content screening system that will enable scientists to perform the most challenging applications with greater speed and sensitivity, accelerating the understanding of disease and discovery of new and more effective treatments.
High-protein diets, like the popular Dr. Dukan diet, increase the long-term risk of developing kidney disease and have a negative effect on renal urinary and morphological markers. What's more, they may promote serious pathologies like nephrolithiasis (calcium kidney stones) because they drastically reduce urinary citrate (an inhibitor of calcium salt crystallization) and urinary pH, and increase urinary calcium (to compensate for the metabolic acidity caused by excess protein).
Dr. Beth Levine, a Howard Hughes Medical Institute Investigator and Director of the Center for Autophagy Research at UT Southwestern Medical Center, has received the 2014 Stanley J. Korsmeyer Award from the American Society for Clinical Investigation.
Scientists have identified a channel present in many pain detecting sensory neurons that acts as a 'brake', limiting spontaneous pain. It is hoped that the new research, published today [22 January] in the Journal of Neuroscience, will ultimately contribute to new pain relief treatments.
An experiment by scientists at the University of Granada, Spain, shows a high-protein diet increases the chance of developing kidney stones and other renal diseases.
Acute myeloid leukemia is a blood cancer, but for many patients the cancer may originate from an unusual source: a mutation in their bone cells.
The human body is daily exposed to external assaults such as bacteria, ultraviolet light or chemical agents. Skin, the largest organ of the body, is the first line of defense against these agents.
UV-B radiation in sunlight is the most important factor for the production of vitamin D, and that is why many people suffer from low levels of vitamin D during the winter months.
Many women are encouraged to quit smoking when they become pregnant using nicotine replacement therapy (NRT) whether as gum, transdermal patches, nasal spray or lozenges.
