In vitro antioxidant activities of methanolic extract of tuberous root of coleous vettiveroides (jacob.) was investigated. The free radical scavenging activity to evaluate by DPPH (2,2 -diphenyl -1picryl hydrazyl) method, Nitric oxide method, Total antioxidant activity. DPPH radical scavenging activity of Methanolic extract and reference standard Rutin IC50 values was found to be 250 μg/ml and ...

synthesis and characterization of 6-(hydroxymethyl)-14, 16-dimethyl-13, 14, 16, 17-tetrahydro-6h-13, 17-epiminodibenzo [e, l] [1, 4] dioxacyclotridecin-15 (7h)-oneabstractnew 6-(hydroxymethyl)-14, 16-dimethyl-13, 14, 16, 17-tetrahydro-6h-13, 17-epiminodibenzo [e, l] [1, 4] dioxacyclotridecin-15 (7h)-one (2a) was synthesized in good yield by the petrenko–kritchenko reaction of 2, 2'-((3-hydroxyp...

The aim of the present study was to compare the effect of patient choice on completion rates and adverse drug reactions for patients treated for latent tuberculosis infection (LTBI) using 3-month rifampicin and isoniazid treatment (3RH) or 6-month isoniazid treatment (6H). Data for all patients treated using 3RH or 6H for LTBI between 1998 and 2004 were analysed. In total, 675 patients attended...

We use results of a 3-D photochemistry/transport model for ozone formation in Mexico City during events in 1997 to investigate ambient concentrations of reactive nitrogen in relation to ozone-precursor sensitivity. Previous results from other locations suggest that ratios such as O3/NOy and H2O2/HNO3 might provide measurement-based indicators for NOx-sensitive or VOC-sensitive conditions. Mexic...

The in vitro activity of R 51,211 (itraconazole, accepted generic name; Janssen Pharmaceutica, Beerse, Belgium), a new orally active triazole, was compared with those of two existing orally active azoles, ketoconazole and BAY n 7133, and a topical agent, Ro 14-4767/002. An agar dilution procedure (Kimmig agar) was performed with 148 isolates of pathogenic fungi. Incubation was at 30 degrees C f...

OBJECTIVE To compare the adverse effects and treatment adherence between 2 months of rifampin plus pyrazinamide (2RZ) and 6 months of isoniazid (6H). BACKGROUND Patients with silicosis in Hong Kong are at high risk of acquiring tuberculosis. A previous study showed that treatment with 6H reduced the risk of silico-tuberculosis by one half. METHOD Patients with silicosis and a Mantoux skin t...

BACKGROUND AND OBJECTIVES The intent of this retrospective study was to assess the operative outcomes of morbidly obese endometrial cancer patients who were treated with either open surgery (OS) or a minimally invasive procedure. METHODS Morbidly obese (body mass index [BMI] > 40 kg/m(2)) patients with endometrial cancer who underwent OS, robotic-assisted laparoscopic surgery (RS), or convent...

Organic compounds released from resins that are commonly employed for trace element separations are known to have a detrimental impact on the quality of isotopic analyses by MC-ICP-MS. A recent study highlighted that such effects can be particularly problematic for Cd stable isotope measurements (M. Gault-Ringold and C. H. Stirling, J. Anal. At. Spectrom., 2012, 27, 449-459). In this case, the ...
