| 1 | Extraction and characterization of alumina nanopowders from aluminum dross by acid dissolution process显示文摘A significant amount of aluminum dross is available as a waste in foundry industries in Bangladesh. In this study, alumina was extracted from aluminum dross collected from two foundry industries situated in Dhamrai and Manikgang, near the capital city, Dhaka. Aluminum dross samples were found to approximately contain 75wt% Al2O3 and 12wt% SiO2. An acid dissolution process was used to recover the alumina value from the dross. The effects of various parameters, e.g., temperature, acid concentration, and leaching time, on the extraction of alumina were studied to optimize the dissolution process. First, Al(OH)3 was produced in the form of a gel. Calcination of the Al(OH)3 gel at 1000°C, 1200°C, and 1400°C for 2 h produced θ-Al2O3,(α+θ)-Al2O3, and α-alumina powder, respectively. Thermal characterization of the Al(OH)3 gel was performed by thermogravimetric/differential thermal analysis(TG/DTA) and differential scanning calorimetry(DSC). The phases and crystallite size of the alumina were determined by X-ray diffraction analysis. The dimensions of the alumina were found to be on the nano level. The chemical compositions of the aluminum dross and alumina were determined by X-ray fluorescence(XRF) spectroscopy. The microstructure and morphology of the alumina were studied with scanning electron microscopy. The purity of the alumina extracted in this study was found to be 99.0%. Thus, it is expected that the obtained alumina powders can be potentially utilized as biomaterials. | Saifur Rahman Sarker Zahangir Alam Rakibul Qadir M A Gafur Mohammad Moniruzzaman | 2015 | International Journal of Minerals,Metallurgy and Materials2015，22，4： | 20 |
| 2 | Liver diseases in pregnancy: Diseases not unique to pregnancy显示文摘Pregnancy is a special clinical state with several normal physiological changes that influence body organs including the liver.Liver disease can cause significant morbidity and mortality in both pregnant women and their infants.Few challenges arise in reaching an accurate diagnosis in light of such physiological changes.Laboratory test results should be carefully interpreted and the knowledge of what normal changes to expect is prudent to avoid clinical misjudgment.Other challenges entail the methods of treatment and their safety for both the mother and the baby.This review summarizes liver diseases that are not unique to pregnancy.We focus on viral hepatitis and its mode of transmission,diagnosis,effect on the pregnancy,the mother,the infant,treatment,and breast-feeding.Autoimmune hepatitis,primary biliary cirrhosis,primary sclerosing cholangitis,Wilson’s disease,Budd Chiari and portal vein thrombosis in pregnancy are also discussed.Pregnancy is rare in patients with cirrhosis because of the metabolic and hormonal changes associated with cirrhosis.Variceal bleeding can happen in up to 38%of cirrhotic pregnant women.Management of portal hypertension during pregnancy is discussed.Pregnancy increases the pathogenicity leading to an increase in the rate of gallstones.We discuss some of the interventions for gallstones in pregnancy if symptoms arise.Finally,we provide an overview of some of the options in managing hepatic adenomas and hepatocellular carcinoma during pregnancy. | Ashraf A Almashhrawi Khulood T Ahmed Rubayat N Rahman Ghassan M Hammoud Jamal A Ibdah | 2013 | World Journal of Gastroenterology2013，19，43： | 17 |

| 4 | Liver diseases in pregnancy: Diseases unique to pregnancy显示文摘Pregnancy is a special clinical state with several normal physiological changes that influence body organs including the liver.Liver disease can cause significant morbidity and mortality in both pregnant women and their infants.This review summarizes liver diseases that are unique to pregnancy.We discuss clinical conditions that are seen only in pregnant women and involve the liver;from Hyperemesis Gravidarum that happens in 1out of 200 pregnancies and Intrahepatic Cholestasis of Pregnancy(0.5%-1.5%prevalence),to the more frequent condition of preeclampsia(10%prevalence)and its severe form;hemolysis,elevated liver enzymes,and a low platelet count syndrome(12%of pregnancies with preeclampsia),to the rare entity of Acute Fatty Liver of Pregnancy(incidence of 1 per 7270 to 13000deliveries).Although pathogeneses behind the development of these aliments are not fully understood,theories have been proposed.Some propose the special physiological changes that accompany pregnancy as a precipitant.Others suggest a constellation of factors including both the mother and her fetus that come together to trigger those unique conditions.Reaching a timely and accurate diagnosis of such conditions can be challenging.The timing of the condition in relation toward which trimester it starts at is a key.Accurate diagnosis can be made using specific clinical findings and blood tests.Some entities have well-defined criteria that help not only in making the diagnosis,but also in classifying the disease according to its severity.Management of these conditions range from simple medical remedies to measures such as immediate termination of the pregnancy.In specific conditions,it is prudent to have expert obstetric and medical specialists teaming up to help improve the outcomes. | Khulood T Ahmed Ashraf A Almashhrawi Rubayat N Rahman Ghassan M Hammoud Jamal A Ibdah | 2013 | World Journal of Gastroenterology2013，19，43： | 10 |
| 5 | Primary hepatocellular carcinoma and metabolic syndrome:An update显示文摘Hepatocellular carcinoma(HCC) is the most common primary liver malignancy. The incidence of hepatocellular carcinoma has increased dramatically by 80% over the past two decades in the United States. Numerous basic science and clinical studies have documented a strong association between hepatocellular carcinoma and the metabolic syndrome. These studies have documented that, in most patients, non-alcoholic fatty liver disease is the hepatic manifestation of the metabolic syndrome, which may progress to hepatocellular carcinoma through the cirrhotic process. However, minority of patients with non-alcoholic fatty liver disease may progress to hepatocellular carcinoma without cirrhosis.This review summarizes the current literature of the link between hepatocellular carcinoma and metabolic syndrome with special emphasis on various components of the metabolic syndrome including risk of association with obesity, diabetes mellitus, hyperlipidemia,and hypertension. Current understanding of pathophysiology, clinical features, treatments, outcomes,and surveillance of hepatocellular carcinoma in the background of metabolic syndrome and non-alcoholic fatty liver disease is reviewed. With the current epidemic of metabolic syndrome, the number of patients with non-alcoholic fatty liver disease is increasing.Subsequently, it is expected that the incidence and prevalence of HCC will also increase. It is very important for the scientific community to shed more light on the pathogenesis of HCC with metabolic syndrome,both with and without cirrhosis. At the same time it is also important to quantify the risk of hepatocellular carcinoma associated with the metabolic syndrome in a prospective setting and develop surveillance recommendations for detection of hepatocellular carcinoma in patients with metabolic syndrome. | Rubayat Rahman Ghassan M Hammoud Ashraf A Al-mashhrawi Khulood T Ahmed Jamal A Ibdah | 2013 | World Journal of Gastrointestinal Oncology2013，5，9： | 8 |
| 6 | Efficient Algorithm for Prolonging Network Lifetime of Wireless Sensor Networks显示文摘One of the fundamental design challenges in designing a Wireless Sensor Network (WSN) is to maximize the network lifetime,as each sensor node of the network is equipped with a limited power battery.To overcome this challenge,different methods were developed in the last few years using such techniques as network protocols,data fusion algorithms using low power,energy efficient routing,and locating optimal sink position.This paper focuses on finding the optimal sink position.Relay nodes are introduced in conjunction with the sensor nodes to mitigate network geometric deficiencies since in most other approaches the sensor nodes close to the sink become heavily involved in data forwarding and,thus,their batteries are quickly depleted.A Particle Swarm Optimization (PSO) based algorithm is used to locate the optimal sink position with respect to those relay nodes to make the network more energy efficient.The relay nodes communicate with the sink instead of the sensor nodes.Tests show that this approach can save at least 40% of the energy and prolong the network lifetime. | Md Nafees Rahman M A Matin | 2011 | Tsinghua Science and Technology2011，16，6： | 6 |
| 7 | Drainage vs. non-drainage after cholecystectomy for acute cholecystitis:a retrospective study显示文摘Many surgeons practice prophylactic drainage after cholecystectomy without reliable evidence,this study was conducted to answer the question whether to drain or not to drain after cholecystectomy for acute calculous cholecystitis.A retrospective review of all patients who had cholecystectomy for acute cholecystitis in Aseer Central Hospital,Abha,Saudi Arabia,was conducted from April 2010 to April 2012.Data were extracted from hospital case files.Preoperative data included clinical presentation,routine investigations and liver function tests.Operative data included excessive adhesions,bleeding,bile leak,and drain insertion.Complicated cases such as pericholecystic collections,mucocele and empyema were also reported.Patients who needed therapeutic drainage were excluded.Postoperative data included hospital stay,volume of drained fluid,time of drain removal,and drain site problems.The study included 103 patients allocated into two groups;group A(n = 38) for patients with operative drain insertion and group B(n = 65) for patients without drain insertion.The number of patients with preoperative diagnosis of acute non-complicated cholecystitis was significantly greater in group B(80%) than group A(36.8%)(P < 0.001).Operative time was significantly longer in group A.All patients who were converted from laparoscopic to open cholecystectomy were in group A.Multivariate analysis revealed that hospital stay was significantly(P < 0.001) longer in patients with preoperative complications.There was no added benefit for prophylactic drain insertion after cholecystectomy for acute calculous cholecystitis in non-complicated or in complicated cases. | Mohammed A Bawahab Walid M Abd El Maksoud Saeed A Alsareii Fahad S Al Amri Hala F Ali Abdul Rahman Nimeri Abdul Rahman M Al Amri Adel A Assiri Mohammed I Abdul Aziz | 2014 | The Journal of Biomedical Research2014，28，3： | 3 |
| 8 | Liver diseases in pregnancy: Liver transplantation in pregnancy显示文摘Pregnancy in patients with advanced liver disease is uncommon as most women with decompensated cirrhosis are infertile and have high rate of anovulation.However,if gestation ensued;it is very challenging and carries high risks for both the mother and the baby such as higher rates of spontaneous abortion,prematurity,pulmonary hypertension,splenic artery aneurysm rupture,postpartum hemorrhage,and a potential for life-threatening variceal hemorrhage and hepatic decompensation.In contrary,with orthotopic liver transplantation,menstruation resumes and most women of childbearing age are able to conceive,give birth and lead a better quality of life.Women with orthotopic liver transplantation seeking pregnancy should be managed carefully by a team consultation with transplant hepatologist,maternal-fetal medicine specialist and other specialists.Pregnant liver transplant recipients need to stay on immunosuppression medication to prevent allograft rejection.Furthermore,these medications need to be monitored carefully and continued throughout pregnancy to avoid potential adverse effects to mother and baby.Thus delaying pregnancy 1 to 2 years after transplantation minimizes fetal exposure to high doses of immunosuppressants.Pregnant female liver transplant patients have a high rate of cesarean delivery likely due to the high rate of prematurity in this population.Recent reports suggest that with close monitoring and multidisciplinary team approach,most female liver transplant recipient of childbearing age will lead a successful pregnancy. | Ghassan M Hammoud Ashraf A Almashhrawi Khulood T Ahmed Rubayat Rahman Jamal A Ibdah | 2013 | World Journal of Gastroenterology2013，19，43： | 3 |
