“A melamine-formaldehyde-urea (MFU) resin was used as adsorbent to clean wastewater containing a basic dye (methylene blue) used to simulate leather and textile processing dyes. Dye removal was followed by measuring the initial and final dye concentration in solution by UV-Vis spectroscopy using the analytical wavelength of lambda = 665 nm and the molar absorptivity of epsilon = (8.43 +/- 0.05) x 10(4) L mol(-1) cm(-1). The concentration range of methylene blue in solution for adsorption experiments
was between 10(-7) and 10(-5) M so as to avoid dye polymerization reactions in solution that would give rise to LCL161 purchase apparent deviations from Beer’s law. Batch and column methods were used for investigating Selleckchem Cilengitide adsorptive removal of dye. Parameters such as pH and contact time were optimized. The capacity of the sorbent for the dye was found by classical adsorption modeling (15.0 mg g(-1)) with the aid of a Langmuir isotherm. The optimal pH for adsorption was 7-8. Adsorption is thought to proceed mainly through cation exchange of methylene blue (MB(+)) with the R-COO (-) exchange groups of the sorbent. Adsorption was fast, and reached an equilibrium within 30 min. Color removal of simulated leather dyeing wastewater was shown to be feasible under optimal conditions. (C) 2009 Wiley Periodicals, Inc.

“We report a case of typhoid rhabdomyolysis with acute renal failure and acute pancreatitis in a 23-year-old Vietnamese male who was admitted to the intensive care unit with a 15-day history of fever followed by severe abdominal pain. On examination, the patient was febrile and his abdomen was diffusely Salubrinal chemical structure tender. Serum creatinine was 533 mu mol/L, pancreatic amylase 1800 U/L and lipase 900 U/L; the myoglobin blood level was high, which is associated
with significant myoglobinuria. Blood, urine and stool culture yielded Salmonella enterica serovar typhi, which was sensitive to ceftriaxon, ampicillin and ciprofloxacin. Ceftriaxon was initiated for a total of 14 days. Subsequently, the patient maintained a good urine output with improved renal parameters and accordingly was discharged. In this report, we review the literature and discuss the pathogenesis of the disease thoroughly. (C) 2008 International Society for Infectious Diseases. Published by Elsevier Ltd.

“A 79-year-old male was treated for 6 months with linezolid for prosthetic knee joint osteomyelitis. At the end of this 6-month period, quantitative stool cultures revealed partial loss of the normal gut flora and concomitant colonization by opportunistic pathogens such as Pseudomonas aeruginosa and other Gram-negatives. Follow-up cultures at 6 weeks after antibiotic discontinuation revealed restoration of the normal flora. Prolonged linezolid administration may lead to replacement of normal gut flora by pathogenic microorganisms, which under certain conditions might cause systemic infections.
