Despite much research the successes of insulin treatrhent in schizophrenia, convulsion therapy in depressive states and prolonged narcosis in emotional disturbance still remain unexplained even to the point, of their still being empirical....
This study developed a novel classification scheme to assign chemicals verifiable mechanism of (eco-)toxicological action allow for grouping, read-across, and in silico model generation. The new unifies extends existing schemes has, at its heart, direct reference molecular initiating events (MIEs) promoting adverse outcomes. is based on three broad domains toxic representing nonspecific toxicit...
We report a rare case of syndrome of inappropriate antidiuretic hormone secretion (SIADH) associated with amyotrophic lateral sclerosis (ALS). A 69-year-old man was admitted to our hospital with sustained hyponatremia. Hyposmolality with elevated urinary osmolality and sodium excretion was observed, which indicated SIADH. The treatment for SIADH was challenging; the patient developed carbon dio...
Human underwater activities rely on an adequate supply of breathable compressed gas, usually air, free from contaminants that could cause incapacitation underwater or post-dive or longer-term health effects. Potentially fatal but well-known hazards are hypoxia secondary to steel cylinder corrosion and carbon monoxide (CO) poisoning due to contaminated intake air. Another phenomenon may be behin...
We sought to determine whether hydrostatic pressure contributed to bradycardia and hypoventilation in hyperbaria. Eight men were studied during exercise at 50, 150, and 250 W while breathing 1) air at 1 bar, 2) helium-oxygen (He-O(2)) at 5.5 bar, 3) sulfur hexafluoride-oxygen (SF(6)-O(2)) at 1.3 bar, and 4) nitrogen-oxygen (N(2)-O(2)) at 5.5 bar. Gas densities were pairwise identical in 1) and ...
