| 1 | Ag recovery from copper anode slime by acid leaching at atmospheric pressure to synthesize silver nanoparticles显示文摘In this paper, recovery of silver from anode slime of Sarcheshmeh copper complex in Iran and subsequent synthesis of silver nanoparticles from leaching solution is investigated. Sarcheshmeh anode slime is mainly consisted of Cu, Ag, Pb and Se. Amount of Ag in the considered anode slime was 5.4%(by weight).The goal was to recover as much as possible Ag from anode slime at atmospheric pressure to synthesize Ag nanoparticles. Therefore, acid leaching was used for this purpose. The anode slime was leached with sulfuric and nitric acid from room to 90 °C at different acid concentrations and the run which yielded the most recovery of Ag was selected for Ag nanoparticles synthesis. At this condition, Cu, Pb and Se are leached as well as Ag. To separate Ag from leach solution HCl was added and silver was precipitated as AgCl which were then dissolved by ammonia solution. The Ag nanoparticles are synthesized from this solution by chemical reduction method by aid of sodium borohydride in the presence of PVP and PEG as stabilizers. The synthesized Ag nanoparticles showed a peak of 394 nm in UV–vis spectrum and TEM images showed a rather uniform Ag nanoparticles of 12 nm. | Atefeh Khaleghi Sattar Ghader Dariush Afzali | 2014 | International Journal of Mining Science and Technology2014，24，2： | 7 |
| 2 | Endoscopic retrograde cholangiopancreatography outcome from a single referral center in Iran显示文摘BACKGROUND: Endoscopic retrograde cholangiopancreato- graphy (ERCP) is the first choice for diagnostic evaluation of the pancreatic and biliary tree and can be accompanied by a high diagnostic sensitivity and a poor therapeutic outcome. In the current study, we described our experiences in the indications, findings, and technical success of ERCP in a sample of the Iranian population admitted to a referral center in Iran. METHODS: In a retrospective review database-based study, 780 patients (393 males and 387 females; mean age 57.5 years) who had undergone diagnostic and therapeutic ERCP with the primary diagnosis of hepatobiliary disorder between 2006 and 2008 at Taleghani Hospital in Tehran were reviewed. The key data were demographic characteristics, clinical information, laboratory parameters, as well as post-ERCP complications. RESULTS: A history of cholecystectomy was found in about one-third (36.3%) of participants and 80 (10.3%) out of 780 patients had a previous history of biliary stone. A minority (1.4%) of the patients suffered from hepatobiliary carcinomas, and 11 patients had cirrhosis. The most common clinical manifestations in the patients undergoing diagnostic ERCP were icterus (47.3%), weight loss (31.2%), and dark urine (26.9%). Selective biliary cannulation was technically successful in 87.0% of the patients; however, cannulation failed in 13.0%. The most frequent final diagnosis of ERCP was common bile duct stone that was detected in 40.1% of the patients. The ERCP results in 11.0% of the patients were normal. Regarding appropriate treatment, successful stenting was performed in 43 patients (15.2%). Among post-ERCP complications, pancreatitis was the most adverse event withan incidence rate of 3.3%. Other complications including local bleeding, cholangitis and gastrointestinal perforation, rarely occurred. Post-ERCP pancreatitis was reported in 1.8% of men and 3.6% of women (P=0.120). Pancreatitis was more common in women below 70 years than in those who were older than 70 years (3.6% versus 0.5%; OR: 8.216, P=0.015). This might be due to the more functionally active pancreas in younger women than in the older ones. However, other complications were similar in the two age groups. CONCLUSIONS: Based on our experience, ERCP indications, final diagnosis and related complications are comparatively consistent with those reported in other countries. The most common post-ERCP complication is pancreatitis that is more often observed in younger patients. | Amir H Mohammad Alizadeh Esmaeil S Afzali Mirhadi Mousavi Yaghoub Moaddab Mohammad R Zali | 2010 | Hepatobiliary & Pancreatic Diseases International2010，9，4： | 3 |
| 3 | Transition of pediatric to adult care in inflammatory bowel disease: Is it as easy as 1, 2, 3?显示文摘Inflammatory bowel disease(IBD)is a heterogeneous group of chronic diseases with a rising prevalence in the pediatric population,and up to 25%of IBD patients are diagnosed before 18 years of age.Adolescents with IBD tend to have more severe and extensive disease and eventually require graduation from pediatric care toadult services.The transition of patients from pediatric to adult gastroenterologists requires careful preparation and coordination,with involvement of all key players to ensure proper collaboration of care and avoid interruption in care.This can be challenging and associated with gaps in delivery of care.The pediatric and adult health paradigms have inherent differences between health care models,as well as health care priorities in IBD.The readiness of the young adult also influences this transition of care,with often times other overlaps in life events,such as school,financial independence and moving away from home.These patients are therefore at higher risk for poorer clinical disease outcomes.The aim of this paper is to review concepts pertinent to transition of care of young adults with IBD to adult care,and provides resources appropriate for an IBD pediatric to adult transition of care model. | Anita Afzali Ghassan Wahbeh | 2017 | World Journal of Gastroenterology2017，23，20： | 2 |
