1Kinetic adsorption of application of carbon nanotubes for Pb(Ⅱ) removal from aqueous solution显示文摘The capability of carbon nanotubes (CNTs) to adsorb lead (Pb) in aqueous solution was investigated. Batch mode adsorption experiment was conducted to determine the effects of pH, agitation speed, CNTs dosage and contact time. The removal of Pb(Ⅱ) reached maximum value 85% or 83% at pH 5 or 40 mg/L of CNTs, respectively. Higher correlation coeffcients from Langmuir isotherm model indicates the strong adsorptions of Pb(Ⅱ) on the surface of CNTs (adsorption capacity Xm = 102.04 mg/g). The results indicates that the highest percentage removal of Pb (96.03%) can be achieved at pH 5, 40 mg/L of CNTs, contact time 80 min, and agitation speed 50 r/min.Nassereldeen A Kabbashi Muataz A Atieh Abdullah Al-Mamun Mohamed E S Mirghami MD Z Alam Noorahayu Yahya 2009Journal of Environmental Sciences2009,21,4:15

3Viral hepatitis prevalence in patients with active and latent tuberculosis显示文摘AIM: To assess the prevalence of hepatitis B virus(HBV) and hepatitis C virus(HCV) infection and association with drug induced liver injury(DILI) in patients undergoing anti-tuberculosis(TB) therapy.METHODS: Four hundred and twenty nine patients with newly diagnosed TB- either active disease or latent infection- who were due to commence antiTB therapy between September 2008 and May 2011 were included. These patients were prospectively tested for serological markers of HBV, HCV and human immunodeficiency virus(HIV) infections- hepatitis B core antigen(HBc Ag), hepatitis B surface antigen(HBs Ag), hepatitis B e antigen, Ig G and Ig M antibody to HBc Ag(anti-HBc), HCV Ig G antibody and HIV antibody using a combination of enzyme-linked immunosorbent assay, Western blot assay and polymerase chain reaction techniques. Patients were reviewed at least monthly during the TB treatment initiation phase. Liver function tests were measured prior to commencement of antiTB therapy and 2-4 wk later. Liver function tests were also performed at any time the patient had significant nausea, vomiting, rash, or felt non-specifically unwell. Fisher's exact test was used to measure significance in comparisons of proportions between groups. A P value of less than 0.05 was considered statistically significant.RESULTS: Of the 429 patients, 270(62.9%) had active TB disease and 159(37.1%) had latent TB infection. 61(14.2%) patients had isolated anti-HBc positivity, 11(2.6%) were also HBs Ag positive and 7(1.6%) were HCV-antibody positive. 16/270 patients with active TB disease compared to 2/159 patients with latent TB infection had markers of chronic viral hepatitis(HBs Ag or HCV antibody positive; P = 0.023). Similarly the proportion of HBs Ag positive patients were significantly greater in the active vs latent TB infection group(10/43 vs 1/29, P = 0.04). The prevalence of chronic HBV or HCV was significantly higher than the estimated United Kingdom prevalence of 0.3% for each. We found no association between DILI and presence of serological markers of HBV or HCV. Three(5.3%) patients with serological markers of HBV or HCV infection had DILI compared to 25(9.5%) patients without; P = 0.04.CONCLUSION: Viral hepatitis screening should be considered in TB patients. DILI risk was not increased in patients with HBV/HCV.Hesam Ahmadi Nooredinvand David W Connell Mahmoud Asgheddi Mohammed Abdullah Marie O'Donoghue Louise Campbell Melissa I Wickremasinghe Ajit Lalvani Onn Min Kon Shahid A Khan 2015World Journal of Gastroenterology2015,21,29:7
4Numerical Analysis of Structural Progressive Collapse to Blast Loads显示文摘After the progressive collapse of Ronan Point apartment in UK in 1968, intensive research effort had been spent on developing guidelines for design of new or strengthening the existing structures to prevent progressive collapse. However, only very few building design codes provide some rather general guidance, no detailed design requirement is given. Progressive collapse of the Alfred P. Murrah Federal building in Oklahoma City and the World Trade Centre (WTC) sparked again tremendous research interest on progressive collapse of structures. Recently, US Department of Defence (DoD) and US General Service Administration (GSA) issued guidelines for structure progressive collapse analysis. These two guidelines are most commonly used, but their accuracy is not known. This paper presents numerical analysis of progressive collapse of an example frame structure to blast loads. The DoD and GSA procedures are also used to analyse the same example structure. Numerical results are compared and discussed. The accuracy and the applicability of the two design guidelines are evaluated.HAO Hong WU Chengqing LI Zhongxian ABDULLAH A K 2006Transactions of Tianjin University2006,12,B09:6
5Effect of low molecular weight heparin (enoxaparin) on congenital cataract surgery显示文摘AIM: To assess the efficacy of intracameral enoxaparin (a low-molecular-weight heparin) infusion, in variable doses on postoperative inflammatory response in congenital cataract surgery.METHODS: It is a prospective, randomized controlled trial. Eighty eyes of 53 children with congenital cataract were enrolled in this study. Every eye had primary posterior capsulorrhexis and intraocular lens (IOL) implantation after lens aspiration. The eyes were divided into 4 equal groups. In group 1 balanced salt solution (BSS) without enoxaparin was used as an irrigation solution. Whereas in group 2, 3 and 4, 40mg, 20mg and 10mg enoxaparin in 500mL BSS was used respectively. The inflammatory response in the anterior chamber was compared among the groups with slit-lamp biomicroscopy.RESULTS: The mean follow-up period was (17.75±3.95) months in group 1, (18.00±5.15) months in group 2, (19.20±5.47) months in group 3 and (18.65±5.16) months in group 4. Mean number of inflammatory cells in the anterior chamber in group 1 was significantly higher than that of group 2, 3, 4 (P<0.001). There was fibrin formation in the anterior chambers of 3 eyes in group 1 and one eye in group 4. There was synechiae formation in 3 eyes of group 1 and one eye of group 4. There was no significant difference among the groups by means of fibrin or synechiae formation (P>0.05). There were IOL precipitates in 4 eyes of group 1 and 2 eyes of group 4. IOL precipitate formation was significantly higher in group 1 than that of group 2 and 3 in which there was no IOL precipitate (P=0.048). There was IOL subluxation in only one eye of group 1, 3 and 4 while no subluxation was observed in group 2 (P>0.05). There was no statistically significant difference detected about IOL subluxation occurance in all 4 groups (P>0.05). CONCLUSION: Complications of cataract surgery in congenital cataract patients associated with postoperative inflammatory response found to be decreased with the use of enoxaparin in intraocular infusion solutions. Furthermore according to our results the anti-inflammatory effect of enoxaparin was dose dependant.Ihsan aa Alparslan Sahin Abdullah Kürsat Cingü Seyhmus Ari Fuat Alakus Yasin inar 2012International Journal of Ophthalmology(English edition)2012,5,5:3

7An assessment of antioxidant status in patients with carbon monoxide poisoning显示文摘BACKGROUND: Carbon monoxide poisoning(COP) is an important cause of mortality and morbidity worldwide. This study was to investigate the levels of serum paraoxonase(PON), arylesterase(ARYL), ceruloplasmin(Cp), and sulfhydryl(-SH) in the treatment of COP, and to further understand the pathophysiology of COP.METHODS: This prospective study comprised 107 individuals with COP(group 1) and 50 healthy volunteers(group 2). Serum, plasma, and erythrocyte samples were taken on admission from all participants with COP. This process was repeated in the 90 th and 180 th minutes of treatment. Samples were taken from the control group only once. The levels of plasma PON, ARYL, Cp activity and-SH were measured in both groups.RESULTS: Age, gender, and carboxyhemoglobin level were not correlated with PON, ARYL, Cp, and-SH levels. PON, ARYL, and-SH levels were signifi cantly decreased in group 1 compared with group 2. Conversely, Cp was signifi cantly elevated in group 1 in contrast to group 2. Although ARYL was lower on admission in patients with COP than that was observed in the 90 th and 180 th minutes(P<0.001), Cp was higher on admission than at the other time points(P<0.001).CONCLUSIONS: Participants with COP had decreased levels of antioxidants(PON, ARLY, and-SH). COP represses the antioxidant system.Suat Zengin Behcet A Sahin Karta Basri Can Mustafa Orkmez Abdullah Taskin Ugur Lok Bediha Gulen Cuma Yildirim Seyithan Taysi 2014World Journal of Emergency Medicine2014,5,2:2

9Breaking wheat yield barriers requires integrated efforts in developing countries显示文摘Most yield progress obtained through the so called 'Green Revolution', particularly in the irrigated areas of Asia, has reached a limit, and major resistance genes are quickly overcome by the appearance of new strains of disease causing organisms.New plant stresses due to a changing environment are difficult to breed for as quickly as the changes occur.There is consequently a continual need for new research programs and breeding strategies aimed at improving yield potential, abiotic stress tolerance and resistance to new, major pests and diseases.Recent advances in plant breeding encompass novel methods of expanding genetic variability and selecting for recombinants, including the development of synthetic hexaploid, hybrid and transgenic wheats.In addition, the use of molecular approaches such as quantitative trait locus(QTL) and association mapping may increase the possibility of directly selecting positive chromosomal regions linked with natural variation for grain yield and stress resistance.The present article reviews the potential contribution of these new approaches and tools to the improvement of wheat yield in farmer's fields, with a special emphasis on the Asian countries, which are major wheat producers, and contain the highest concentration of resource-poor wheat farmers.Saeed Rauf Maria Zaharieva Marilyn L Warburton ZHANG Ping-zhi Abdullah M AL-Sadi Farghama Khalil Marcin Kozak Sultan A Tariq 2015Journal of Integrative Agriculture2015,14,8:2
10Anticoagulation and antiplatelets as prophylaxis for hepatic artery thrombosis after liver transplantation显示文摘Hepatic artery thrombosis(HAT) is the most serious vascular complication after liver transplantation. Multiple risk factors have been identified to impact its development. Changes in haemostasis associated with end stage liver disease and the disturbance of the coagulation and anticoagulation cascades play an important role in development of this lethal complication. Early recognition and therapeutic intervention is mandatory to avoid its consequences. Pharmacological prophylaxis, by the use of antiplatelet or anticoagulant agents, is an important tool to reduce its incidence and prevent graft loss. Only a few studies have shown a clear benefit of antiplatelet agents in reducing HAT occurrence, however, these studies are limited by being retrospective and by inhomogeneous populations. The use of anticoagulants such as heparin is associated with an improvement in the outcomes mainly when used for a high-risk patients like living related liver recipients. The major concern when using these agents is the tendency to increase bleeding complications in a setting of already unstable haemostasis. Hence, monitoring of their administration and careful selection of patients to be treated are of great importance. Well-designed clinical studies are still needed to further explore their effects and to formulate proper protocols that can be implemented safely.Abdullah A Algarni Moustafa M Mourad Simon R Bramhall 2015World Journal of Hepatology2015,7,9:2
11Outcomes of staged hepatectomies for liver malignancy显示文摘Liver malignancies are the fifth most common cause of death worldwide.Surgical intervention with curative intent is the treatment of choice for liver tumors as it provides long-term survival.However,only 20%of patients with metastatic liver lesions can be managed by curative liver resection.In most of the cases,hepatectomy is not feasible because of insufficient future liver remnant(FLR).Two-stage hepatectomy is advocated to achieve liver resection in a patient who is considered to not be a candidate for resection.Procedures of staged hepatectomy include conventional two-stage hepatectomy,portal vein embolization,and associating liver partition and portal vein ligation for a staged hepatectomy.Technical success is high for each of these procedures but variable between them.All the procedures have been reported as being effective in achieving a satisfactory FLR and completing the second-stage resection.Moreover,the overall survival and disease-free survival rates have improved significantly for patients who were otherwise considered nonresectable;yet,an increase in the morbidity and mortality rates has been observed.We suggest that this type of procedure should be carried out in high-flow centers and through a multidisciplinary approach.An experienced surgeon is key to the success of those interventions.Naif A Albati Ali A Korairi Ibrahim Al Hasan Helayel K Almodhaiberi Abdullah A Algarni 2019World Journal of Hepatology2019,11,6:2
12Helicobacter pylori infection and gastropathy:A comparison between Indonesian and Japanese patients显示文摘AIM:To compare the effects of Helicobacter pylori(H pylori) infection on gastropathy between Indonesian and Japanese patients.METHODS:Biopsy specimens were obtained during upper gastrointestinal endoscopy from 167 subjects(125 Indonesians and 42 Japanese) with uninvestigated symptoms of dyspepsia.The specimens were analyzed for the presence of H pylori using urease analysis,histopathology,and cell culture.The grade and activity of gastritis was assessed using the updated Sydney system.RESULTS:The percentages of Indonesian and Japanese patients who were H pylori-positive at the antrum or body of the stomach were similar(68% and 59.5%,respectively;P=0.316).Of those who were H pylori-positive,more Japanese patients than Indonesian patients had high levels of polymorphonuclear cells(P=0.001),mononuclear cells(P=0.013),glandular atrophy(P=0.000),and intestinal metaplasia(P=0.011) in both the antrum and body of the stomach.CONCLUSION:The grade of gastritis and prevalence of mucosal atrophy and intestinal metaplasia were higher in Japanese patients.The difference between Indonesian and Japanese patients was signifi cant.Murdani Abdullah Hiroyuki Ohtsuka Abdul Aziz Rani Tadashi Sato Ari F Syam Masayuki A Fujino 2009World Journal of Gastroenterology2009,15,39:2
13Outcomes of revision external dacryocystorhinostomy and nasal intubation by bicanalicular silicone tubing under endonasal endoscopic guidance显示文摘AIM: To evaluate the long-term treatment outcomes in patients who underwent revision of external dacryocysto- rhinostomy (DCR) and nasal intubation by bicanalicular silicone tubing (BSTI) under endonasal endoscopic guidance. · METHODS: Data from 28 patients with recurrent dacryocystitis were retrospectively reviewed. Revision external DCR and bicanalicular nasal intubation by silicone tubing under endonasal endoscopic guidance was performed in 28 eyes of 28 patients. The patients were evaluated with respect to the reason of recurrence, time to recurrence, time to revision, duration of follow-up and surgical success. · RESULTS: Endoscopic endonasal examination detected an osteotomy-side obstruction by the excessive granulation tissue in 24 patients (86%), nasal septal deviation in three patients (10%) and nasal polyp in one patient (4%). Recurrence occurred after a mean duration of 5.3±3.7 months following the first operation. The mean time between the first DCR operation and the revision DCR was 11.5 ± 9.3 months. After a mean follow-up of 14.9±7.8 months, the rate of anatomic success alone was 85% (24/28); the rate of subjective success was 78% (22/28). · CONCLUSION: Revision external DCR and bicanalicular nasal intubation by silicone tubing under endonasal endoscopic guidance can be recommended in patients with recurrent dacryocystitis as a surgical approach that achieves satisfactory objective and subjective success rates.Seyhmus Ari Abdullah Kürsat Cingü Alparslan Sahin Ramazan Gün Vefa Kinis ihsan aa 2012International Journal of Ophthalmology(English edition)2012,5,2:2
