Purpose We report the outcomes of patients treated with palliative radiotherapy (pRT) to the primarytumour in the context of well-controlled metastatic disease after initial chemotherapy. Materials and MethodsClinical records of 132 patients with metastatic esophago-gastric (OG) cancer treated withpalliative chemotherapy (pCT) between January 2009 and June 2013 were reviewed. Ninetysevenpatients had responding or stable disease after 3 months of chemotherapy, of whom53 patients received pRT to the primary tumour after initial chemotherapy in the presenceof well-controlled metastatic disease (group A, pCT-RT). The remaining 44 patients weretreated with pCT alone (group B, pCT). Treatment-related outcomes were assessed in abovegroups including time to local progression (TTLP), progression-free and overall survival. ResultsThe median overall survival for patients treated with pRT after initial chemotherapy (groupA) was 23.3 months (95% confidence interval [CI], 17.70 to 28.89 months) and significantlyhigher than the 14 months (95% CI, 10.91 to 17.08 months) in patients treated with pCTalone (group B) (p < 0.001). The use of pCT-RT was an independent predictor of OS in multivariateanalysis. Local recurrence was observed in 12/53 of patients (23%) in group Acompared to 16/44 (36%) in group B. The median TTLP was significantly higher in patientsafter pCT-RT at 17.3 months (5.23 months to 44.50 months) compared to 8.3 months(range, 4.10 to 25.23 months) in patients treated with pCT alone (p=0.006). ConclusionThe possibility of pRT influencing systemic disease in advanced OG cancer has not beenreported, and results from the present study present strong arguments for investigation ofthis therapeutic strategy in a randomized trial.
Multiparameter Flow Cytometry: Advances in High Resolution Analysis
O'Donnell, Erika A.,Ernst, David N.,Hingorani, Ravi The Korean Association of Immunobiologists 2013 Immune Network Vol.13 No.2
Over the past 40 years, flow cytometry has emerged as a leading, application-rich technology that supports high-resolution characterization of individual cells which function in complex cellular networks such as the immune system. This brief overview highlights advances in multiparameter flow cytometric technologies and reagent applications for characterization and functional analysis of cells modulating the immune network. These advances significantly support highthroughput and high-content analyses and enable an integrated understanding of the cellular and molecular interactions that underlie complex biological systems.

A systematic isolation and characterization study for Cassia auriculata (CA) seeds resulted in identifying antidiabetic compounds 1,3,8-trihydroxyanthraquinone and quercetin, quercetin-3-O-rutinoside, gallic acid, caffeic acid, ferulic acid, and ellagic acid. The ultra-high-performance liquid chromatography based triple quadrupole mass spectrometry methodology was developed and validated for simultaneous identification and confirmation of these compounds from CA seeds. Multiple reaction monitoring (MRM) based quantification method was developed with MRM optimizer software for MS<sub>1</sub> and MS<sub>2</sub> mass analysis. The method was optimized on precursor ions and product ions with the ion ratio of each compound. The calibration curves of seven bioactive analytes showed excellent linearity (r<sup>2</sup> ≥ 0.99). The quantitation results found precise (RSD, < 10 %) with good recoveries (84.58 to 101.42%). The matrix effect and extraction recoveries were found within the range (91.66 to 102.11%) for the CA seeds. This is the first MS/MS-based methodology applied to quantifying seven antidiabetic compounds in CA seeds and its extract for quality control purposes.
