Twenty-four urine specimens were collected from randomly selected members of the crew of the U.S. Navy Submarine NATHAN HALE, SSBN623, while at sea on a routine patrol mission. Specimens were collected three days after submergence, and again a few days before return to port. Twenty-one men received daily dosages of 310 mg of magnesium oxide orally, while nineteen served as controls. Urine speci...

This study examined the effects of widely used antacids (aluminum hydroxide, magnesium oxide, and calcium carbonate), ferrous sulfate, and ranitidine on the absorption of a fluorinated quinolone, (-)-(S)-9-fluoro-3-methyl-10-(4-methyl-1-piperazinyl)-7-oxo-2,3-dihydro- 7H- pyrido-[1,2,3,-de][1,4]benzoxazine-6-carboxylic acid hemihydrate (DR-3355), in healthy male volunteers enrolled in three sep...

Nanometal oxides were extracted from cement factories wastes and employed to proliferate skin cancer cells using MTT (Methyl Thiazolyl Tetraolium) assay. assay results for cell line A375,for CaO NPs the best concentration was 200 μg/mL,The viability reduced 57.28% while IC50 (69.66) g/mL A375 normal WRL68 significantly higher (231.2 g/mL). The cytotoxicity of CaO: MgO: Fe2O3 NPs, at concentrati...

Oxygen Evolution Reaction In article number 2207695, Byung-Hyun Kim, HyukSu Han, and co-workers develop an iridium doped calcium copper titanate exhibiting ultrahigh mass activity for acidic oxygen evolution reaction (OER). This work reposts the design of electrocatalysts OER using colossal dielectric perovskite oxide.
