The present study analyzed the action of sodium trimetaphosphate (TMP) and/or fluoride on hydroxyapatite. Hydroxyapatite powder was suspended in different solutions: deionized water, 500 µg F/mL, 1,100 µg F/mL, 1%TMP, 3%TMP, 500 µg F/mL plus 1%TMP and 500 µg F/mL plus 3%TMP. The pH value of the solutions was reduced to 4.0 and after 30 min, raised to 7.0 (three times). After pH-cycling, the sam...

A Monte Carlo simulation demonstrated that 1 g of meropenem (MEM) every 8 h (q8h) (3-h infusion) has a higher target attainment rate against Pseudomonas aeruginosa than either 500 mg of MEM q8h (3-h infusion) or 0.5 g of imipenem-cilastatin (I-C) q6h (1-h infusion). For other pathogens, 500 mg of MEM q8h was equivalent or superior to I-C.

500 cases of Esophago-Gastroscopy were evaluated at the Shahid Moddares teaching and research medical center. Endoscopic diagnosis were:  38% Gastritis, 24% Duodenal Ulcer, 8% Esophageal Carcinoma, 6% Gastric Carcinoma, 6% Gastric Ulcer, 6% Hiatal Hernia, 3% Esophageal Varises.  In 68% of these cases Gastroscopy findings were in Agreement with Radiology reports. 

In the title compound, 0.75C12H14ClNO2·0.25C12H14ClNO, which is an adduct comprising 0.75 4-hy-droxy-piperidin-1-yl or 0.25 4-piperidin-1-yl substituents on a common (4-chloro-phen-yl)methanone component; the dihedral angles between the benzene ring and the two piperidine rings are 51.6 (3) and 89.5 (7)°, respectively. The hy-droxy-piperidine ring is in a bis-ectional oriention (bi) with the ph...

This study investigated the effect of silane and surfactant treatments of graphene nanoplatelets (GnPs) on the mechanical and thermal properties of silicone rubber (SR) composites. GnPs were modified with aminopropyltriethoxysilane (APTES), vinyltrimethoxysilane (VTMS), and Triton X-100, and then the pristine GnPs and functionalized GnPs were individually incorporated into the SR. Compared with...
