1Application of GIS to Estimate Soil Erosion Using RUSLE显示文摘This paper describes the use of the Arc/Info and ArcView GIS tools to estimate soil erosion with Universal Soil Loss Equation (USLE).Calculations are be done by using capabilities available.This study start with a digital elevation model (DEM) of Shaanxi,which was created by digitizing contour and spot heights from the topographic map on 1∶250 000 scale and grid themes for the USLE K and C factors.It is note worthy that USLE K can be obtained by adding the K factor as an attribute to a soil theme’s table.The C can be obtained from tables or using the information about land use and management given by USLE program.A land use theme can be used to add the C factors as an attribute field.The purpose of this study is to establish spatial information of soil erosion using USLE and GIS and discuss the analysis of the soil erosion and slope failures in GIS and formulate the possible framework.Mushtak Talib Jabbar 2003Geo-Spatial Information Science2003,6,1:7
2磷钨酸负载的非贵金属单原子催化剂:乙烯环氧化的理论研究显示文摘基于第一性原理,本文系统研究了过渡金属单原子(铁,钴,镍,钌,铑,钯,锇,铱,铂)负载在磷钨酸(PTA)催化剂上的几何和电子结构,并进一步研究了乙烯环氧化在铁单原子催化剂上的可能反应机理.我们发现PTA最可能结合过渡金属单原子的位置是四配位中空位.乙烯环氧化催化活性的理论计算表明,非贵金属Fe1-PTA具有可观的吸附能,这是引发此催化循环的关键物理量.我们进一步进行了铁单原子和PTA结合的成键分析,发现电荷从铁单原子转移到PTA团簇,并且强烈的Fe–O共价金属-载体相互作用(CMSI)是其高稳定性的基础.在催化剂Fe1-PTA上可能的乙烯环氧化催化机理共包括三步:1)氧气分子通过电荷转移吸附在Fe1-PTA上;2)第一个乙烯分子攻击吸附在Fe1-PTA上的氧气分子,随后形成C2H4O;3)表面吸附的氧原子和第二个乙烯分子生成C2H4O,完成催化循环.本研究发现,Fe1-PTA对于乙烯环氧化主要通过Eley-Rideal机理进行.本工作为发展高效多相非贵金属单原子乙烯环氧化催化剂提供了理论依据.Shamraiz Hussain Talib 于小虎 于琦 Sambath Baskaran 李隽 2020Science China Materials2020,63,6:5
3Hepatoprotective effect of Solatium xanthocarpum fruit extract against CCl_4 induced acute liver toxicity in experimental animals显示文摘Objective:To investigate the hepatoprotective potential of Solonum xanthocarpum(Solanaceae) (S.xanthocarpum) in experimental rats to validate its traditional claim.Methods:50%ethanolic fruit extract of S.xanthocarpum(SXE,100.200 or 400 mg/kg hods weight) was administered daily for 14davs in experimental animals.Liver injury was induced chemically,by CCl4 administration (1 mL/kg i.p.).The hepatoprotective activity was assessed using various biochemical parameters like aspartate aminotransferase(AST),alanine aminotransferase(ALT).Serum alkaline phosphatise (SALP) and total bilirubin.Meanwhile,in vivo antioxidant activities as lipid peroxidation(LPO), reduced glutathione(GSH).superoxide dismutase(SOD) and calalase(CAT) were screened along with histopathological studies.Results:Obtained results demonstrated that the treatment with SXE significantly(P<0.05- <0.001) and dose-dcpendcntly prevented chemically induced increase in serum levels of hepatic enzymes.Furthermore.SXE significantly(up to P<0.001) reduced the lipid peroxidation in the liver tissue and restored activities of defence antioxidant enzymes GSH,SOU and catalasc towards normal levels.Histopathology of the liver tissue showed that SXE attenuated the hepatocellular necrosis and led to reduction of inflammatory cells inflltration. Conclusions:The results of this study strongly indicate the protective effect of SXE against acute liver injun which may he attributed to its hepatoprotective activity,and there by scientifically support its traditional use.Ramesh K Gupta Talib Hussain G.Panigrahi Avik Das Gireesh Narayan Singh K Sweety Md Faiyazuddin Chandana Venkateswara Rao 2011Asian Pacific Journal of Tropical Medicine2011,4,12:4
4A case of enterolith small bowel obstruction and jejunal diverticulosis显示文摘We reported a case of 79-year old woman with known large bowel diverticulosis presenting with small bowel obstruction due to stone impaction - found on plain abdominal X-ray.Contrast studies demonstrated small bowel diverticulosis.At laparotomy, the gall bladder was normal with no stones and no abnormal communication with small bowel - excluding the possibility of a gallstone ileus. Analysis of the stone revealed a composition of bile pigments and calcium oxalate.This was a rare case of small bowel obstruction due to enterolith formation - made distinctive by calcification (previously unreported in the proximal small bowel).Buhussan Hayee Hamed Noor Khan Talib Al-Mishlab John F McPartlin 2003World Journal of Gastroenterology2003,9,4:4

6Silymarin-laden PVP-PEG polymeric composite for enhanced aqueous solubility and dissolution rate: Preparation and in vitro characterization显示文摘The aim of this work was to develop, optimize and characterize a silymarin-laden polyvinylpyrrolidone(PVP)-polyethylene glycol(PEG) polymeric composite to resolve low aqueous solubility and dissolution rate problem of the drug. A number of silymarin-laden polymeric formulations were fabricated with different quantities of PVP K-30 and PEG 6000 by the solvent-evaporation method. The effect of PVP K-30 and PEG 6000 on the aqueous solubility and dissolution rate was investigated. The optimized formulation and its constituents were characterized using powder X-ray diffraction(PXRD), differential scanning calorimetry(DSC), scanning electron microscopy(SEM) and Fourier transform infrared spectroscopy(FTIR) techniques. Both the PEG 6000 and PVP K-30 positively affected the aqueous solubility and dissolution rate of the drug. In particular, a formulation consisting of silymarin, PVP K-30 and PEG 6000(0.25/1.5/1.5, w/w/w) furnished the highest solubility(24.3972.95 mg/mL) and an excellent dissolution profile( $100% in 40 min). The solubility enhancement with this formulation was $ 1150-fold as compared to plain silymarin powder. Moreover, all the constituents existed in the amorphous state in this silymarin-laden PVP-PEG polymeric composite. Accordingly, this formulation might be a promising tool to administer silymarin with an enhanced effect via the oral route.Abid Mehmood Yousaf Usman Rashid Malik Yasser Shahzad Tariq Mahmood Talib Hussain 2019Journal of Pharmaceutical Analysis2019,9,1:3

8Evaluation of chemopreventive effect of Fumaria indica against N-nitrosodiethylamine and CCl_4-induced hepatocellular carcinoma in Wistar rats显示文摘Objective:To investigation the chemopreventive potential of Fumaria indica(F.indica) extract(FIE) on N-nitrosodiethylamine and CCl4-induced hepatocarcinogenesis in Wislar rats.Methods:The experimental animals were divided into six groups(n=6).Hepatocellular carcinoma was induced by single intraperitoneal injection of N-nitrosodiethylamine(NDEA) in normal saline at a dose of 200 mg/kg body weight followed by weekly subcutaneous injections of CCl4(3 mL/kg/week) for 6 weeks,as the promoter of carcinogenic effect.After administration of the carcinogen,200 and 400 mg/kg of FIE were administered orally once a day throughout the study.At the end of 20 weeks,the body weight,liver weight and relative liver weight were measured.The percentage of nodule incidence and liver cancer markers such as aspartate transaminase(AST),alanine transaminase(ALT),alkaline phosphatase(ALP),γ-glutamyl transferase(γ-GT),total bilirubin level(TBL),α-feto protein(AFP) and carcinoembryonic antigen were estimated along with histopathological investigation in experimental groups of rats. Results:Obtained results demonstrated that the cotreatment with FIE significantly prevented the decrease of the body weight and also increased in relative liver weight caused by NDEA. The treatment with FIE significantly reduced the nodule incidence and nodule multiplicity in the rats after NDEA administration.The levels of liver cancer markers such as AST,ALT,ALP,γ-glutamyl transferase,TBL,AFP and carcinoembryonic antigen were substantially increased by NDEA treatment.However,FIE treatment significantly reduced the liver injury and restored the entire liver cancer markers.Histological observations of liver tissues too correlated with the biochemical observations.Conclusions:These finding powerfully supports that F.indica exert chemopreventive effect by suppressing the tumor burden and restoring the activities of hepatic cancer marker enzymes on NDEA and CCl4-induced hepatocarcinogenesis in Wistar rats.Talib Hussain Hefazat H Siddiqui Sheeba Fareed M Vijayakumar Chandana V Rao 2012Asian Pacific Journal of Tropical Medicine2012,5,8:3

The biochemical observations were supplemented by histopathological examination.Results:The results demonstrated that treatment withS.xanthocarpumsignificantly(P<0.05-P<0.001) and dose-dependently prevented drug induced increase in serum levels of hepatic enzymes. Furthermore,S. xanthocarpumsignificantly(up toP<0.001) reduced the LPO in the liver tissue and restored activities of defence antioxidant enzymes GSH, SOD and CAT towards normal levels. Histopathology of the liver tissue showed that S. xanthocarpumattenuated the hepatocellular necrosis and led to reduction in inflammatory cells infiltration.Conclusions:The results of this study strongly indicate the protective effect of S. xanthocarpumagainst liver injury which may be attributed to its hepatoprotective activity, and thereby scientifically support its traditional use.Talib Hussain Ramesh K Gupta Sweety K Mohd Sajid Khan Md Sarfaraj Hussain Md Arif Arshad Hussain Md Faiyazuddin Chandana Venkateswara Rao 2012Asian Pacific Journal of Tropical Biomedicine2012,2,6:2
15Using Remote Sensing and GIS Techniques to Study Soil Degradation Processes in North Shaanxi Province,China显示文摘Satellite image data and thematic map data were used to provide comprehensive views of surface-bound conditions such as soil and vegetation degradation. The current work applies a computerized parametric methodology, developed by FAO, UNEP and UNESCO to assess and evaluate soil degradation at 1∶250 000 mapping scale. The study area is located in the arid and semi-arid zone of the northern part of Shaanxi Province in China, a region with considerable agricultural potential; Landsat TM images were utilized to provide recent data on land cover and use of the area. ARC/INFO and ArcView softwares were used to manage and manipulate thematic data, to process satellite images, and tabular data source. ER mapper software is utilized to derive the normalized difference vegetation index (ND VI) values while field data to estimate soil erodibility ( SE ) factor. A system is established for rating soil parameters, slope, climate factor and human factor activity. The rating values serve as inputs into a modified universal soil loss equation (USLE) to calculate the present state and risk for soil degradation processes, namely soil wind erosion. The produced maps and tabular data show the risk and the present status of different soil degradation processes. The study area, in general, is exposed to high risk of wind erosion and high hazards of water erosion. Several desertification maps were produced, which reflect the desertification types persisting in the study area. Wind erosion, water erosion, vegetation degradation, physical degradation and salinization are the basic desertification maps, and others are combinations of these basic maps. In terms of statistic analysis, 33.75 % of the total land area (120.330 0 ha) is considered as sand or sand dune, and not included in our analysis of desertification. About 29.41 % of the total land area has slight or moderate desertification and 37.465 % is facing severe desertification.Mushtak Talib Jabbar 2003Journal of China University of Geosciences2003,14,4:2
16Platelet biomarkers in Alzheimer's disease显示文摘The search for diagnostic and prognostic markers in Alzheimer's disease(AD) has been an area of active research in the last decades. Biochemical markers are correlates of intracerebral changes that can be identified in biological fluids, namely: peripheral blood(total blood, red and white blood cells, platelets, plasma and serum), saliva, urine and cerebrospinal fluid. An important feature of a biomarker is that it can be measured objectively and evaluated as(1) an indicator of disease mechanisms(markers of core pathogenic processes or the expression of downstream effects of these processes), or(2) biochemical responses to pharmacological or therapeutic intervention, which can be indicative of disease modification. Platelets have been used in neuropharmacological models since the mid-fifties, as they share several homeostatic functions with neurons, such as accumulation and release of neurotransmitters, responsiveness to variations in calcium concentration, and expression of membrane-bound compounds. Recent studies have shown that platelets also express several components related to the pathogenesis of AD,in particular to the amyloid cascade and the regulation of oxidative stress: thus they can be used in the search for biomarkers of the disease process. For instance, platelets are the most important source of circulating forms of the amyloid precursor protein and other important proteins such as Tau and glycogen synthase kinase-3B. Moreover, platelets express enzymes involved in membrane homeostasis(e.g., phospholipase A2), and markers of the inflammatory process and oxidative stress. In this review we summarize the available literature and discuss evidence concerning the potential use of platelet markers in AD.Leda L Talib Helena PG Joaquim Orestes V Forlenza 2012World Journal of Psychiatry2012,2,6:2

20Composition and source apportionment of dust fall around a natural lake显示文摘The aim of this study was to determine the source apportionment of dust fall around Lake Chini, Malaysia. Samples were collected monthly between December 2012 and March2013 at seven sampling stations located around Lake Chini. The samples were filtered to separate the dissolved and undissolved solids. The ionic compositions(NO-3, SO2-4, Cl-and NH+4) were determined using ion chromatography(IC) while major elements(K, Na, Ca and Mg) and trace metals(Zn, Fe, Al, Ni, Mn, Cr, Pb and Cd) were determined using inductively coupled plasma mass spectrometry(ICP-MS). The results showed that the average concentration of total solids around Lake Chini was 93.49 ± 16.16 mg/(m2·day). SO2-4, Na and Zn dominated the dissolved portion of the dust fall. The enrichment factors(EF) revealed that the source of the trace metals and major elements in the rain water was anthropogenic, except for Fe. Hierarchical agglomerative cluster analysis(HACA) classified the seven monitoring stations and 16 variables into five groups and three groups respectively. A coupled receptor model, principal component analysis multiple linear regression(PCA-MLR), revealed that the sources of dust fall in Lake Chini were dominated by agricultural and biomass burning(42%),followed by the earth's crust(28%), sea spray(16%) and a mixture of soil dust and vehicle emissions(14%).Mohd Talib Latif Sofia Aida Ngah Doreena Dominick Intan Suraya Razak Xinxin Guo Thunwadee Srithawirat Idris Mushrifah 2015Journal of Environmental Sciences2015,27,7:1
