“We designed a case-control study to determine the plasma homocysteine (Hey) level and evaluate the potential role of the met hylenetetrahydrofolate reductase (MTHFR) C677T gene polymorphism in colorectal cancer (CRC). Total Hcy was quantified using the fluorescence polarization immunoassay (FPIA) on the IMx analyzer. Genomic DNA was analyzed by the real-time polymerase chain reaction

(RT-PCR). The plasma levels of Hcy in the CRC group (12.63 +/- 3.11 mu mol/l) were significantly higher compared with those in the control group (10.87 +/- 2.42 mu mol/l; P<0.05). The frequency of the MTHFR 677TT genotype in CRC patients was markedly high. The MTHFR 677TT DMXAA genotype was significantly correlated with an increased risk of CRC (odds ratio, 1.671; 95% confidence interval, 1.094-2.553; P=0.018). This study suggests that the MTHFR C677T polymorphism selleck chemicals llc indicates susceptibility to CRC and is correlated with CRC pathogenesis, suggesting that the homozygous variant MTHFR C677T polymorphism is a candidate risk factor for CRC.”
“Pyrazinamide (PZA) plays the important role in shortening the tuberculosis treatment period and in treating MDR-TB. Phenotypic PZA susceptibility methods are limited because they require specialized acidified media, which

increases costs and complexity. In this study we developed a genotypic high resolution melt (HRM) analysis technique to detect pncA mutations associated with PZA resistant Mycobacterium buy JPH203 tuberculosis. Seven overlapping primer pairs were designed to cover the entire pncA gene and upstream regions. Each gene segment was individually amplified by real-time PCR followed by HRM analysis. The assay was evaluated on 98 clinical M. tuberculosis isolates (41 PZA susceptible by MGIT method, 55 PZA resistant, 2 undetermined). HRM was 94%

concordant to full-length sequencing results, with most discrepancies attributable to mixed populations per HRM or transversions. Sequencing and HRM yielded 82% and 84% concordance, respectively, to phenotypic PZA susceptibilities by MGIT, with most discrepancies attributable to isolates with wild-type pncA but phenotypic PZA resistance. This HRM technique is a simple and high-throughput method for screening clinical M. tuberculosis samples for PZA resistance. (C) 2013 Elsevier Ltd. All rights reserved.”
“BACKGROUND An expected side effect of external beam radiation therapy for retinoblastoma is cataract formation, which impairs a child’s visual development and an ophthalmologist’s ability to examine the eye. When surgery is indicated, the potential complications can be vision-or life-threatening. Here we report the results of cataract extraction with intraocular lens placement in young children with retinoblastoma.\n\nMETHODS A retrospective chart review of all patients at St.
