introduction:guillain-barre syndrome(gbs) is the most common cause of acute flaccid paralysis. respiratory failure is the most serious short-term complication of gbs and invasive mechanical ventilation is required in 30% of patients.moreover,60% of those who are intubated develop major complications including pnemonia,sepsis,gi bleeding and pulmonary embolism. thus respiratory failure predictio...

Hepatocytes have a great replicative capacity and are capable of repopulating the liver. Previous studies have suggested that the autonomic nervous system regulates liver regeneration and apoptosis. Moreover, the central nervous system modulates them through the autonomic nervous system. The lateral hypothalamus (LH) area and the ventromedial hypothalamus (VMH) nucleus have been studied for the...

We developed a smart-phone based system to measure the activities of autonomic nervous system during everyday life. Using commonly marketed smart phones, by touching your fingertips on the phone’s camera over a short time of about 30 seconds, it will detect changes in the brightness of the blood flow and in turn analyze your heart rate variability. By using this system, about 100,000 cases were...

To elucidate the role of autonomic nervous system in functional dyspepsia patients, we examined 24-h heart rate variability: the basal levels, responses after lunch, cold pressor and mental arithmetic tests, and the efficacy of an autonomic drug (tofisopam). The high-frequency component (HF: 0.15-0.40 Hz) and the ratio of HF to the low-frequency component (LF: 0.04-0.15 Hz; LF/HF ratio) were us...

The polyvagal theory introduced a new perspective relating autonomic function to behavior, that included an appreciation of the autonomic nervous system as a "system," the identification of neural circuits involved in the regulation of autonomic state, and an interpretation of autonomic reactivity as adaptive within the context of the phylogeny of the vertebrate autonomic nervous system. The pa...

Congenital insensitivity to pain with anhidrosis is a rare disease of the nervous system which causes one to lose his/her feeling of pain. The disease is subtype four of hereditary sensory and autonomic neuropathy (HSAN IV) that results from NTRK1 gene defect. Direct sequencing was performed to screen NTRK1 for mutations. The result revealed a homozygous deletion of adenine on intron 14 that ma...

ANS (Autonomic Nervous System) is involved in energy metabolism and regulation of cardiovascular system. ANS of obese individuals is chronically altered. Various studies demonstrate important modifications in the autonomic control of obese adults and adolescents, there is scarce information on obese children, and the findings remain inconclusive. So work should be done to investigate the cardio...

BACKGROUND: Pregnancy with malfunction of the autonomic nervous system deteriorates by enhancing such clinical syndromes as respiratory, asthenic, hemorrhagic, aggravating peripheral vascular disorders. Cognitive disorder is frequent in pregnancy and it is coupled with a range of undesirable outcomes, including maternal death. AIM: To carry out the analysis of cognitive disorders in pregnant wo...

Almost all bodily functions are dependent on the functioning of the autonomic nervous system– from the cardiovascular system, the gastrointestinal tract, the evacuative and sexual organs, to the regulation of temperature, metabolism and tissue defense. Balanced functioning of this system is an important basis of our life and well-being. The Integrative Action of the Autonomic Nervous System: Ne...
