3Hepatoprotective and immunomodulatory properties of aqueous extract of Curcuma longa in carbon tetra chloride intoxicated Swiss albino mice显示文摘Objective:To evaluate the hepatoprotective and immunotherapeutic effects of aqueous extract of turmeric rhizome in CCl_4 intoxicated Swiss albino mice.Methods:first group of mice(n=5) received CCl_4 treatment at a dose of 0.5 mL/kg bw(i.p.) for 7 days.Second group was fed orally the aqueous extract of turmeric at a dose of 50 mg/kg bw for IS days.The third group was given both the turmeric extract(for 15 days,orally) and CCl_4(for last 7 days,i.p.).The fourth group was kept as a control.To study the liver function,the transaminase enzymes(SGOT and SGPT) and bilirubin level were measured in the serum of respective groups.For assaying the immunotherapeutic action of Curcuma longa(C.longa),non specific host response parameters like morphological alteration,phagocytosis,nitric oxide release,myeloperoxidase release and intracellular killing capacity of peritoneal macrophages were studied from the respective groups.Results:The result of present study suggested that CCl_4 administration increased the level of SCOT and SGPT and bilirubin level in serum.However,the aqueous extract of turmeric reduced the level of SGOT, SCFT and bilirubin in CCl_4 intoxicated mice.Apart from damaging the liver system,CCl_4 also reduced non specific host response parameters like morphological alteration,phagocytosis, nitric oxide release,myeloperoxidase release and intracellular killing capacity of peritoneal macrophages.Administration of aqueous extract of C.longa offered significant protection from these damaging actions of CCl_4 on the non specific host response in the peritoneal macrophages of CCl_4 intoxicated mice.Conclusions:In conclusion,the present study suggests that C.longa has immunotherapeutic properties along with its ability to ameliorate hepatotoxicity.Mahuya Sengupta Gauri Dutta Sharma Biswajit Chakraborty 2011Asian Pacific Journal of Tropical Biomedicine2011,1,3:11
4Performance of sand and shredded rubber tire mixture as a natural base isolator for earthquake protection显示文摘The performance of a well-designed layer of sand, and composites like layer of sand mixed with shredded rubber tire(RSM) as low cost base isolators, is studied in shake table tests in the laboratory. The building foundation is modeled by a 200 mm by 200 mm and 40 mm thick rigid plexi-glass block. The block is placed in the middle of a 1m by 1m tank filled with sand. The selected base isolator is placed between the block and the sand foundation. Accelerometers are placed on top of the footing and foundation sand layer. The displacement of the footing is also measured by LVDT. The whole setup is mounted on a shake table and subjected to sinusoidal motions with varying amplitude and frequency. Sand is found to be effective only at very high amplitude(> 0.65 g) of motions. The performance of a composite consisting of sand and 50% shredded rubber tire placed under the footing is found to be most promising as a low-cost effective base isolator.Srijit Bandyopadhyay Aniruddha Sengupta G.R.Reddy 2015Earthquake Engineering and Engineering Vibration2015,14,4:10
5RNAi-Mediated Silencing of ITPK Gene Reduces Phytic Acid Content,Alters Transcripts of Phytic Acid Biosynthetic Genes,and Modulates Mineral Distribution in Rice Seeds显示文摘Phytic acid is the principal storage form of phosphorus in plant seeds and an essential signalling molecule in several regulatory processes of plant development.However,it is known as an anti-nutrient compound owing to its potent chelating property.Thus,reducing the phytic acid content in crops is desirable.Studies involving regulation of MIPS and IPK1 genes to generate low phytate rice have been reported earlier.However,the functional significance of OsITPK and the effect of its down-regulation on phytic acid content and the associated pleiotropic effects on rice have not yet been investigated.In this study,tissue specific RNA interference(RNAi)-mediated down-regulation of a major ITPK homolog(OsITP5/6K-1)resulted in 46.2%decrease in phytic acid content of T2 transgenic seeds with a subsequent 3-fold enhancement in the inorganic phosphorus content.Silencing of OsITP5/6K-1 altered the transcript levels of essential phytic acid pathway genes,without significantly affecting the transcript levels of other OsITPK homologs.Furthermore,the mapping of elements through X-ray microfluorescence analysis revealed significant changes in the spatial distribution pattern and translocation of elements in low phytate seeds.Additionally,low phytate polished seeds exhibited 1.3-fold and 1.6-fold enhancement in iron and zinc content in the grain endosperm,respectively.Silencing of OsITP5/6K-1 also altered the amino acid and myo-inositol content of the transgenic seeds.Our results successfully established that RNAi-mediated silencing of OsITP5/6K-1 gene significantly reduced the phytate levels in seeds without hampering the germination potential of seeds and plant growth.The present study provided an insight into the mechanism of phytic acid biosynthesis pathway.Aritra KARMAKAR Sananda BHATTACHARYA Shinjini SENGUPTA Nusrat ALI Sailendra Nath SARKAR Karabi DATTA Swapan K.DATTA 2020Rice science2020,27,4:7
6Thioredoxin and glutaredoxin-mediated redox regulation of ribonucleotide reductase显示文摘Ribonucleotide reductase(RNR), the rate-limitingenzyme in DNA synthesis, catalyzes reduction of thedifferent ribonucleotides to their corresponding deoxyri-bonucleotides. The crucial role of RNR in DNA synthesishas made it an important target for the development ofantiviral and anticancer drugs. Taking account of the re-cent developments in this field of research, this reviewfocuses on the role of thioredoxin and glutaredoxin sys-tems in the redox reactions of the RNR catalysis.Rajib Sengupta Arne Holmgren 2014World Journal of Biological Chemistry2014,5,1:6
7Anti-viral role of toll like receptor 4 in hepatitis B virus infection: An in vitro study显示文摘AIM Toll like receptors plays a significant anti-viral role in different infections. The aim of this study was to look into the role of toll like receptor 4(TLR4) in hepatitis B virus(HBV) infection.METHODS Real time PCR was used to analyze the transcription of TLR4 signaling molecules, cell cycle regulators and HBV DNA viral load after triggering the Hep G2.2.15 cells with TLR4 specific ligand. Nuclear factor(NF)-κB translocation on TLR4 activation was analyzed using microscopic techniques. Protein and cell cycle analysis was done using Western Blot and FACS respectively.RESULTS The present study shows that TLR4 activation represses HBV infection. As a result of HBV suppression, there are several changes in host factors which include partial release in G1/S cell cycle arrest and changes in host epigenetic marks. Finally, it was observed that anti-viral action of TLR4 takes place through the NF-κB pathway.CONCLUSION The study shows that TLR4 activation in HBV infection brings about changes in hepatocyte microenvironment and can be used for developing a promising therapeutic target in future.Dipanwita Das Neelakshi Sarkar Isha Sengupta Ananya Pal Debraj Saha Manikankana Bandopadhyay Chandrima Das Jimmy Narayan Shivram Prasad Singh Runu Chakravarty 2016World Journal of Gastroenterology2016,22,47:4
8印度Ganga-Meghna-Brahmaputra平原及周围地区与孟加拉国地下水砷污染及其对健康影响的19年研究显示文摘基于近19年对印度Ganga—Meghna—Brahmaputra(简称GMB)平原(面积569749km^2,人口超过5亿)地下水砷污染的调查,可以确定印度Ganga—Brahmaputra平原(包括北方邦、比哈尔邦、恰尔康得邦、西孟加拉邦、阿萨姆邦)和孟加拉国普遍受到砷的污染。近期的调查研究也表明,除米佐拉姆邦外,其他各邦的地下水也受到不同程度的砷污染。至今为止.已对印度各邦和孟加拧国的175000份和50808份压把井水样进行了含砷量检测。并组织了一支包括皮肤科、神经科和妇产科医生在内的有经验的专家组,对上述地区125000人进行了临床检查,其中9%患有砷导致的皮肤病损症状。至今共采集分析了60000份生物样品。包括发样、指甲、尿样及皮肤鳞屑,其中80%的样品含砷量超过允许值,很多人由此受到砷的亚临床损害。在上述砷暴露地区.19000名儿童经过检查,近1100人患有砷导致的皮肤病损。该调查结果表明.儿童比成人更容易受到砷的毒性损害。在这种状况下.应着力解决饮水安全问题来减轻砷的苊害.Ahamed S Hossain MA Mukharjee A Sengupta MK Das B Nayak B Pal A Mukherjee SC Pati S Dutta RN Saha KC Quamruzzaman Q Chakraborti D 付松波(译) 孙殿军(审校) 2007中国地方病学杂志2007,26,1:3
9Golgi localization and dynamics of hyaluronan binding protein 1 (HABP1/p32/C1QBP) during the cell cycle显示文摘Hyaluronan binding protein 1 (HABP1) is a negatively charged multifunctional mammalian protein with a unique structural fold. Despite the fact that HABP1 possesses mitochondrial localization signal, it has also been localized to other cellular compartments. Using indirect immunofluorescence, we examined the sub-cellular localization of HABP1 and its dynamics during mitosis. We wanted to determine whether it distributes in any distinctive manner after mitotic nuclear envelope disassembly or is dispersed randomly throughout the cell. Our results reveal the golgi localization of HABP1 and demonstrate its complete dispersion throughout the cell during mitosis. This distinctive distribution pattern of HABP1 during mitosis resembles its ligand hyaluronan, suggesting that in concert with each other the two molecules play critical roles in this dynamic process.Aniruddha SENGUPTA Bhaswati BANERJEE Rakesh K.

14Impact of inflammatory bowel disease activity and thiopurine therapy on birth weight: A meta-analysis显示文摘AIM To investigate the effect of disease activity or thiopurine use on low birth weight and small for gestational age in women with inflammatory bowel disease(IBD).METHODS Selection criteria included all relevant articles on the effect of disease activity or thiopurine use on the risk of low birth weight(LBW) or small for gestational age(SGA) among pregnant women with IBD. Sixtynine abstracts were identified,35 papers were full text reviewed and,only 14 of them met inclusion criteria. Raw data were extracted to generate the relative risk of LBW or SGA. Quality was assessed using the Newcastle Ottawa Scale.RESULTS This meta-analysis is reported according to PRISMA guidelines. Fourteen studies met inclusion criteria,and nine reported raw data suitable for meta-analysis. We found an increased risk ratio of both SGA and LBW in women with active IBD,when compared with women in remission: 1.3 for SGA(4 studies,95%CI: 1.0-1.6,P = 0.04) and 2.0 for LBW(4 studies,95%CI: 1.5-2.7,P < 0.0001). Women on thiopurines during pregnancy had a higher risk of LBW(RR 1.4,95%CI: 1.1-1.9,P = 0.007) compared with non-treated women,but when adjusted for disease activity there was no significant effect on LBW(RR 1.2,95%CI: 0.6-2.2,P = 0.6). No differences were observed regarding SGA(2 studies; RR 0.9,95%CI: 0.7-1.2,P = 0.5). CONCLUSION Women with active IBD during pregnancy have a higher risk of LBW and SGA in their neonates. This should be considered in treatment decisions during pregnancy.Begona Gonzalez-Suarez Shreyashee Sengupta Alan C Moss 2017World Journal of Gastroenterology2017,23,45:3
