1Photosynthesis, Growth and Antioxidant Metabolism in Mustard (Brassica juncea L.) Cultivars Differing in Cadmium Tolerance显示文摘Two mustard (Brassica juncea L. Czern and Coss.) cultivars, Pusa Jai Kisan and SS2 differing in cadmium (Cd) tolerance were treated with 0, 25 and 50 μmol L-1 Cd to study the physiological basis of difference in Cd tolerance. Cultivar SS2 (Cd sensitive) accumulated greater Cd in leaves than Pusa Jai Kisan (Cd tolerant). Further, SS2 also exhibited higher contents of thiobarbituric acid reactive substances (TBARS) and H2O2 and electrolyte leakage. However, the activities of antioxidant enzymes, catalase (CAT), ascorbate peroxidase (APX), dehydroascorbate reductase (DHAR), and glutathione reductase (GR) were higher in Pusa Jai Kisan than those in SS2. Contrarily, the activity of superoxide dismutase (SOD) was higher in SS2 than that in Pusa Jai Kisan and was the greatest at 25 μmol L-1 Cd. Treatment of 25 μmol L-1 Cd induced the maximum activity of enzymes. However, the activity of GR increased up to 50 μmol L-1 Cd in both the cultivars. The non-enzymatic antioxidants ascorbate (AsA) and glutathione (GSH) were higher in Pusa Jai Kisan than that in SS2, whereas dehydroascorbate (DHA) and oxidized glutathione (GSSG) were higher in SS2. Photosynthesis and growth were adversely and maximally decreased by 50 μmol L-1 Cd treatment in both the cultivars, but SS2 exhibited greater reductions. The protection of photosynthesis and growth and lesser reduction in Pusa Jai Kisan were associated with its capacity to restrict accumulation of Cd in leaves resulting in lower level of TBARS and H2O2 and electrolyte leakage. Moreover, Pusa Jai Kisan exhibited efficient antioxidant metabolism for removal of Cd-induced reactive oxygen species.Noushina Iqbal Asim Masood Rahat Nazar Shabina Syeed Nafees A Khan 2010Agricultural Sciences in China2010,9,4:8

3e-antigen-negative chronic hepatitis B in Bangladesh显示文摘BACKGROUND:Bangladesh is a densely populated country where about 10 million people are chronically infected with hepatitis B virus(HBV).The aim of the present study was to evaluate the biochemical,virological and histological characteristics of HBeAg-negative chronic hepatitis B(CHB). METHODS:Patients were included in this study if they were chronically infected with HBV with detectable DNA.The patients who were co-infected with human immunodeficiency virus,hepatitis delta virus or hepatitis C virus,and previously subjected to antiviral treatment,and those with hepatocellular carcinoma were excluded.The study was conducted during the period of January 2001 to December 2007.During this period 2617 patients with CHB were studied.HBeAg-positive cases were included to compare the characteristics.Among them,237 cases underwent liver biopsy. RESULTS:2296 patients(87.7%)were male,with a mean age of 28.9±13.7 years.2375 patients(90.8%)had CHB,and 242(9.2%)were cirrhotic.HBV DNA levels were 7.6±1.5 copies/ml,ALT was 111.3±212.5 U/L,and AST was 91.5± 148.9 U/L.The number of HBeAg-negative CHB cases was 1039(39.7%).HBeAg-negative patients with a lower DNA load were older,and they had more fibrotic changes in the liver than HBeAg-positive patients.The two groups did not differ in necroinflammatory activity,but the former had lower ALT and AST values.Cirrhosis was more common in e-antigen-negative patients.CONCLUSIONS:e-antigen-negative CHB patients are older and have more hepatic fibrosis patients than HBeAg-positive patients,although they have similar necroinflammatory activity.Nooruddin Ahmad Shahinul Alam Golam Mustafa Abul Barkat Muhammad Adnan Rahat Hasan Baig Mobin Khan 2008Hepatobiliary & Pancreatic Diseases International2008,7,4:6

5层状双氢氧化物(LDHs)的合成及应用(英文)显示文摘Layered double hydroxides, a class of anionic clays possessing sandwich like structure in which negative anions are sandwiched into positively charged metal layers in a repeating manner, have been studied extensively. Layered double hydroxides could be fabricated with combination of different divalent(Cd^(2+), Mn^(2+), Fe^(2+), Pb^(2+)) and trivalent(Al^(3+), Cr^(3+), Fe^(3+)) metals and layered arrangement imparts unique properties such as adsorption properties and catalytic properties in these compounds. Exciting feature of these compounds is the memory effect. There are a number of methods to synthesize these layered compounds, such as co-precipitation, hydrothermal, sol-gel, urea hydrolysis,?etc. The synthesized LDHs can be characterized morphologically and compositionally i.e. scanning electron microscopy, transmission electron microscopy, powder X-Ray diffraction, Mossbauer spectroscopy, thermogravimetric analysis, XPS, etc. The wonderful feature of layered double hydroxides is the pliancy of interlayer space enabling them to accommodate various anionic species, and high surface area making them efficient in numerous applications such as adsorbents, anion exchange, catalysts, and biological compatible.Saba Jamil Afaaf Rahat Alvi Shanza Rauf Khan Muhammad Ramzan Saeed Ashraf Janjua 2019化学进展2019,31,2:3
6第三次工业革命:经济综述显示文摘新的工业革命也许可以定义为:在最先进的工业社会中,信息技术的提高与广泛的应用,及其对第三世界的渗透.所谓信息技术,是指计算机和通信的相互混合,以及电子学在生产过程和商业上——从工厂车间的计算机程序化机器人到工业客户衣袋里'精巧的'信用卡——日益增加的应用.在发展中国家的公共和私人部门中,当其工业、通信系统及管理工作适应现代化需要时,这些国家的革命就有可能取得进展.Rahat Nabi Khan 徐慈 1988科学与社会1988,,2:2

14Role of microRNA in regulation of myeloma-related angiogenesis and survival显示文摘Multiple myeloma(MM)is a malignant disease causedby clonal proliferation of plasma cells that result in monoclonal gammopathy and severe end organ damage.Despite the uniform clinical signs,the disease is very diverse in terms of the nature and sequence of the underlying molecular events.Multiple cellular processes are involved in helping the malignant cells to remain viable and maintain proliferative properties in the hypoxic microenvironment of the bone marrow.Specifically,the process of angiogenesis,triggered by the interactions between the malignant MM cells and the stroma cells around them,was found to be critical for MM progression.In this review we highlight the current understanding about the epigenetic regulation of the proliferation and apoptosis of MM cells and its dependency on angiogenesis in the bone marrow that is carried out by different micro RNAs.Michal A Rahat Meir Preis 2016World Journal of Hematology2016,5,2:1
