The comparative measuring of the dust-seizure-efficiency of aspirators is being carried out by a practice-related treatment of 5 cylindrical-shaped specimen made of a commercial cobalt-chromium-alloy with aluminum-oxide-grinding instruments and silicone-rubber-polishers. A small-filter-apparatus
Rhabdomyolysis results from skeletal muscle injury and release of muscle cell contents into plasma. A number of etiologic factors have been reported for the condition, including strenuous exercise, weight lifting, trauma, seizure, sepsis, and alcohol and drug abuse. Hundreds of drugs also reportedly
Chromium nitride coating is now the norm for improving the wear resistance of high-performance mechanical components. Even so, to prevent the seizure issue between the contacting interfaces, the prerequisites are oil or solid lubricants which would however lose the lubricating functionality at
Carbon monoxide (CO) and the excitatory amino acid glutamate both dilate cerebral arterioles in newborn pigs. The key enzyme in CO synthesis is heme oxygenase, which is highly expressed in neurons with glutamatergic receptor activity as well as cerebral microvessels. During seizures the
Fifteen metallic species, silver (Ag), aluminum (Al), calcium (Ca), cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), potassium (K), magnesium (Mg), manganese (Mn), sodium (Na), nickel (Ni), lead (Pb), strontium (Sr) and zinc (Zn), were determined in 46 cocaine samples confiscated by the Spanish
Six metals (copper, magnesium, barium, nickel, chromium and lead) were determined in two separate batches of seized ecstasy tablets by graphite furnace atomic absorption spectroscopy (GFAAS) following digestion with nitric acid and hydrogen peroxide. Large intra-batch variations were found as
Brain abscesses frequently cause symptoms such as seizures, delirium, paresis and sensory deficits that could reflect brain edema, increased intracranial pressure, or tissue destruction. However, it is also possible that pus constituents could disturb neuronal function in the surrounding brain
A 29-year-old single woman had recurrent stroke-like episodes. She developed loss of consciousness, myoclonic seizures, and lactic acidosis. She died at the age of 30. A muscle biopsy study revealed mitochondrial myopathy, and the postmortem biochemical analysis demonstrated decreased cytochrome c
Psychopharmacologic treatment is playing a greater role in the management of patients with eating disorders. In this paper, we review randomized, placebo-controlled trials (RCTs) conducted in anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED), and other eating disorders over
