Journal of Analytical Sciences, Methods and Instrumentation 2013年第3期3卷 173-178页

作者： Muniasamy Neerathilingam Sai Gandham Falguni Patel Mohammad nasiruddin Centre for Cellular Molecular Platforms (C-CAMP) NCBS-TIFR GKVK Campus Bangalore India Centre for Cellular Molecular Platforms (C-CAMP) NCBS-TIFR GKVK Campus Bangalore India&Institute of Molecular Medicine (IMM) University of Texas Health Science Center Houston USA. Institute of Molecular Medicine (IMM) University of Texas Health Science Center Houston USA.

NF-κB plays a crucial role in regulating various biological processes including innate and adaptive immunity, inflammation, stress responses, B-cell development, and lymphoid organogenesis. Currently, several assays like electrophoretic mobility shift assay (EMSA), enzyme-linked immunosorbent assay (ELISA), fluorescence resonance energy transfer (FRET) and time-resolved fluorescence resonance energy transfer (TR-FRET) are widely used for studying the NFκB intraction with β-IFN-κB binding oligo. Each of these techniques has varying utility with distinct strengths and weaknesses. We describe a method AlphaLISA to identify NFκB p50 protein and β-IFN-κB binding oligo sequence and interaction is efficient at a given concentration (10 nM) in the EMSA and Biacore’s SPR assays. The method has many advantages such as use of small volume, high throughput (HTP), convenience of sample preparation and data analysis.

Coal Chemistry and Morphology of Thar Reserves,Pakistan

引用

Journal of Minerals and Materials Characterization and Engineering 2012年第8期11卷 817-824页

作者： Anila Sarwar M. nasiruddin Khan Kaniz Fizza Azhar Department of Chemistry University of Karachi Karachi Pakistan Fuel Research Centre Pakistan Council of Scientific & Industrial Research Karachi Pakistan Scientific Information Centre Pakistan Council of Scientific & Industrial Research Karachi Pakistan

The surface of Thar coal has been characterized by spectroscopic, microscopic and chemical methods using atomic absorption spectroscopy, fourier transform infrared analysis, X-ray diffraction, scanned electron microscopy and pH titration. The samples contained high moisture, low volatile and low to moderate sulfur content and ranked as lignite (heating value 2541 - 4289 btu/lb on moist, mineral-matter-free basis). Scanned electron micrographs show porous matrix with calcium, potassium or sodium minerals. Fourier transform infrared analysis confirmed the presence of aluminum, silica and hydrate mineral constituents also. The spectra showed C=C aromatic groups at 1604 - 1609 cm-1. Phenolic ester and carboxylic acid are identified by C=O stretching vibration peaks at 1702 cm-1. The peaks of quartz and kaolinite were observed at 900 - 1100 cm-1. Point of zero charge of Thar coal has been estimated as 6.00 to 6.27 through adsorption of H+ and OH- ions by suspending coal particles in aqueous electrolyte solution. Oxygen containing functional groups, mineral matter, and metal oxides are found to have a remarkable impact on point of zero charge. The surface characterization study will be helpful in the separation of hydrophilic impurities during coal preparation processes considering pzc as the controlling

模块化多电平换流器(MMC)是电力电子技术当前研究的重要课题之一。尽管目前学术界已经提出了大量MMC的调制算法和控制策略的研究,但是对于它们的分类、分析和评估还缺少普遍共识。本文的主题是研究基于差模-共模分量分解的MMC控制策略。本文采用载波移相调制算法以减小无源器件(桥臂电感、电容等)的体积和成本,同时提出了控制目标以及对应的控制策略验证和分类方法。MMC的主要控制目标是控制其每个相单元的共模电流和差模电流。共模电流导致桥臂电流RMS值(均方根值)增大,从而增大系统的功率损耗,降低系统效率,因而必须进行充分抑制。MMC的共模电流是由于上、下桥臂模块电容电压的不同以及相单元的直流电压的波动所引起的。为控制共模电流,本文建立单相MMC仿真模型,采用基于比例-积分-谐振(PIR)的闭环控制策略。其作用是抑制共模电流中的二次谐波电流,该二次谐波电流增大了输出电流的RMS值和谐波。同时,输出电流采用基于比例-谐振(PR)控制器的闭环控制方法。该控制器主要用来消除共模电流引起的谐波。此外,为了保持电容电压均衡,电容电压经过陷波器以提取直流电压分量,从而实现电容电压平衡和消除基频电压波动。基于MATLAB/SIMULINK仿真软件的仿真结果验证了本文研究的控制策略的有效。

Impact of MGMT Promoter Methylation as a Prognostic Marker in Patients with High Grade Glioma: A Single-Center Observational Study

引用

Journal of Cancer Therapy 2019年第10期10卷 806-814页

作者： Vinu Sarathy Srinivasa Belagutty Jayappa Bhanu Lalkota Kiran Pura Krishnamurthy Vishal Kulkarni Samuel Luke Koramati nasiruddin Mohammad Radheshyam Naik Department of Medical Oncology Health Care Global Enterprises Ltd. Bangalore India

Objectives: 1) To correlate the methylation status of the O-6-methylguanine-DNA-methyltransferase (MGMT promoter gene) and response to alkylating agent-based treatment in high-grade gliomas. Background: The MGMT gene is epigenetically silenced by promoter hypermethylation in gliomas and this modification has emerged as a relevant predictor of therapeutic response. Methods: 20 cases of high-grade glioma were analyzed for MGMT promoter methylation by methylation-specific PCR. Response to treatment and overall survival data were recorded and data analysed. Results: MGMT promoter methylation was found in 60% of gliomas by methylation-specific PCR. The mean survival time of glioblastoma patients submitted to adjuvant therapy was significantly higher among patients with MGMT promoter methylation (P = 0.035) and methylation status was an independent predictive factor that was associated with improved prognosis. Discussion and Conclusion: MGMT promoter methylation status was a more reliable predictor of response to adjuvant therapy and prognosis of high-grade gliomas. A subset of patients received irinotecan and bevacizumab in the second line setting and patients with unmethylated MGMT seemed to do better than the MGMT promoter methylated group.

Journal of Cancer Therapy 2017年第9期8卷 838-844页

Background: Lung cancer is the leading cause of cancer-related death worldwide with an estimated 1.6 million new cases diagnosed each year. According to standard guidelines in NSCLC, the effectiveness of combined chemotherapy regimen comprises of pemetrexed and platinum, and very few reports are available in Indian population. This study shows the experience with pemetrexed and platinum combination chemotherapy in metastatic NSCLC in first line setting. Methods: Total 61 patients with following inclusion criteria were recruited such as: 1) PS of 1 and 2;2) NSCLC of non-squamous histology;3) locally advanced or metastatic disease at diagnosis;4) should have received minimum 3 cycles of pemetrexed and platinum as first line treatment and or continued for 6 cycles;5) EGFR/ALK mutated or EGFR/ALK unknown patients but must have received upfront chemo. Primary endpoint of the present study is to assess Disease Control Rate (DCR) (CR + PR + SD). Progression Free Survival, OS and Toxicity assessment were secondary endpoints. Results: The mean number of average chemotherapy cycles was found to be 4.38. The range of chemotherapy was 2 - 6 cycles. Disease control rate, defined as (CR + PR + SD), was seen in 44 (72.1%) patients. (PR in 26 (42.62%), SD 18 (29.5%)), Progressive disease (PD) was observed in 17 (27.9%) patients. Overall study showed that patients had PFS of 9.414 months (95% CI 6.709 - 12.120) and OS of 13.437 months (95% CI 10.721 - 16.153). Conclusion: Pemetrexed and platinum combination is effective and well-tolerated chemotherapy regimen in patients with metastatic adenocarcinoma lung cancer patients. Pemetrexed and cisplatin may be more effective in particular. Early switch over to TKIs is preferred immediately after obtaining molecular subtype result.
