<h3>Objective:</h3> We evaluated patterns of tumor progression in patients with recurrent glioblastoma who were treated bevacizumab (BEV) alone or combination irinotecan (CPT-11) while participating the BRAIN study. <h3>Methods:</h3> An independent neuroradiologist reviewed MRI scans at baseline and received BEV (n = 85) BEV+CPT-11 82) on BRAIN. Tumor scored as local, distant, diffuse, multifocal. Median progression-free survival (PFS) overall (OS) estimated using Kaplan-Meier methods....
To assess whether nutritional deficiency increases susceptibility to arsenic-related health effects.Assessment of nutrition was based on a 24 h recall method all dietary constituents.Epidemiological cross-sectional study conducted in an arsenic endemic area West Bengal with groundwater contamination.The composed two groups – Group 1 (cases, n 108) exhibiting skin lesions and 2 (exposed controls, 100) not age- sex-matched having similar exposure through drinking water levels urine hair.Both...
Various systemic manifestations are reported to be caused by chronic arsenic exposure in the population living Indo-Bangladesh subcontinent. This study from West Bengal assesses likelihood of occurrence hypertension (HTN) individuals resident an area high groundwater contamination with (Nadia district) compared those a non-contaminated (Hoogly Bengal, India. Two hundred and eight participants (Group 1) were recruited cross-sectional six villages Nadia district 100 controls 2) village Hoogly...
2008 Background: Patients (pts) with relapsed glioblastoma (GBM) suffer considerable morbidity and mortality. We analyzed updated safety survival data from the BRAIN trial of bevacizumab (BV) alone or in combination irinotecan (IR). Methods: Results BRAIN, a phase II, open-label, multicenter, randomized, noncomparative GBM at first second relapse, during planned treatment period (PTP) BV (n=85) BV+IR (nn=8582), have been reported (J Clin Oncol 27:4733-4740, 2009). BV-arm pts progression who...
The authors investigated association of arsenic intake through water and diet level in urine people living endemic region West Bengal supplied with arsenic-safe (<50 μg L−1). Out 94 (Group-1A) study participants using <50 L−1, 72 (Group-1B) were taking <10 L−1. Multiple regressions analysis conducted on the Group-1A showed that daily dose from found to be significantly positively associated urinary level. However, was Group-1B only, but no significant this group. In a separate analysis, out...
Determination of chromium by electrothermal atomization atomic absorption spectrometry with normal electrographite tube has been investigated after microwave-assisted digestion sediment and botanical samples. Microwave oven-assisted procedures involve aqua regia, HF (for sediments) H2O2 in a poly (tetrafluoroethylene)(PTFE) reactor followed treatment saturated H3BO3(where is used the earlier step). Comparative studies on determination using three previously reported chemical modifiers,...
An indirect method is described for the determination of free cyanide in industrial waste effluent samples by atomic absorption spectrometry (AAS). In an alkaline medium, forms a stable complex species [Cu(BPTC)(CN)](BPTC = 2-benzoylpyridine thiosemicarbazone), which can be extracted into mixture isobutyl methyl ketone–isopentyl alcohol (7 + 1) with efficiency greater than 98.5%. The extract analysed directly copper (and hence indirectly cyanide) flame AAS. calibration graph linear up to 5.7...
The removal of arsenic from drinking water by filtration through modified fly-ash bed is discussed. preparation and characteristics the material effects different parameters like pH presence other constituents are described. Various compounds in synthetic mixtures as well samples containing have been investigated. effectiveness for control has demonstrated taking quantities arsenic(III) arsenic(V) salts. results filtering were found to be satisfactory which makes it a low cost treatment...
