White titanium dioxide pigment has been produced by two main processes. The sulfate and the chloride processes. Each of these two routes requires different feedstocks. However, economic and environmental pressures are shifting the world balance of titanium dioxide production away from sulphate based manufacture towards the more cost effective and cleaner chloride route. According to usage of titanium dioxide, the nano sized TiO 2 was produced by the sulfuric acid and hydrocholoric acid leaching by using Sonochemical technique during the leaching process. No adding extra materials and no milling after precipitate, no vaporization during the leaching are advantages of this work which reduced the processes of leaching. All of determination techniques of particle size (Zeta Sizer, XRD, SEM, and TEM) prove this matter. The p...

One of the most important factors that put the safety of various communities at risk is the threats caused by crime occurrence. This paper is aimed to spatially analyze crime occurrence in various regions of Iran with an emphasis on safety. The research method is descriptive-analytical and a documentary and library data collection method is used. In this paper, the Similarity, COPRAS, mean rank method, and cluster analysis method are applied. The final results of the cluster analysis based on the mean rank method indicate a wide gap between the provinces of the country in terms of survey indicators, so that the final coefficient obtained for the provinces in the sixth cluster (the most unsafe group) is about 45 times of the final coefficient of the provinces in the first cluster (the safest group).

MATERIALS AND METHODS We retrospectively analyzed 806 adult liver transplant recipients from Shiraz, Iran, to determine those with intraoperative-detected portal vein thrombosis. Patients with this complication were compared with age- and sex-matched patients without this complication. Background diseases, surgery parameters, hospital admission, reoperation, rethrombosis, acute rejection, and use of antico-agulants were assessed. Cox proportional hazards, logistic regression, and random classification forest and random survival forest plots were used for data analyses. RESULTS Mean age of patients was 44.7 ± 13.2 years. Patients with intraoperative-detected portal vein thrombosis (n = 91; 11.3%) had mortality ratio of 2.9 (range, 1.0-8.6) and 2-year survival of 78% versus 2-year survival rate of 92% in patients without this disease. Median time of survival in patients with this complication who died was 2 weeks versus 10 months in patients who died and did not have this complication. Random classification forest plots showed that high fasting blood sugar, autoimmune hepatitis, low prothrombin time, and cryptogenic cirrhosis were (in order) the main predictors of this complication. Random survival forest plots revealed that low prothrombin time, having intraoperative-detected portal vein thrombosis, Model for End Stage Liver Disease score, primary sclerosing cholangitis, diabetes mellitus, and hepatocellular carcinoma were (in order) the main predictors of death in liver transplant recipients. Low body mass index was associated with mortality in patients with intraoperative-detected portal vein thrombosis (by Cox proportional hazards). CONCLUSIONS One of every 9 liver transplant patients had intraoperative-detected portal vein thrombosis. Hazard of death was 2.9, and death occurred far earlier in patients with this complication. Improvements in diabetes mellitus care, prothrombin time, Model for End-Stage Liver Disease score, and body mass index may improve outcomes of these patients.

This study aimed at investigating the development and timing of CMV infection after liver transplantation and its relation to post-transplantation HHV-6 activation. Methods: Patients undergoing liver transplantation were enrolled, regardless of their age, place of residence, or their liver failure etiology. Blood samples were collected at baseline and every week for a period of 12 weeks and were tested for anti-CMV IgG and anti-HHV-6 IgG, CMV pp65 antigenemia, as well as CMV and HHV-6 DNA using the Polymerase Chain Reaction (PCR) method. Results: Among 46 liver transplant recipients, 17 (36.9%) developed CMV infection within 3 months after transplantation. Before transplantation, 42 (91.3%) and 41 (89.1%) recipients were seropositive for CMV and HHV-6, respectively. Fifty percent of patients were positive for CMV antigenemia, among which 73.9% became symptomatic for CMV infection. Half of the patients had positive test results for CMV PCR with a significant relationship between the CMV viral load and the development of symptomatic CMV infection (P = 0.001). Twenty-five (54.3%) patients had positive test results for HHV-6 PCR with a significant relationship between HHV-6 positivity and the development of clinical presentation (P = 0.002). The average post-transplantation time to HHV-6 and CMV activation was 19.4 ± 86.5 and 28.4 ± 60.5 days, respectively, with a linear relationship in the regression analysis. Conclusions: The HHV-6 infection, either as primary infection or reactivation, leads to an increased risk of CMV infection and symptomatic disease after liver transplantation. Activation of HHV-6 precedes the CMV activation in time.

Methods: Patients undergoing liver transplantation were enrolled, regardless of their age, place of residence, or their liver failure etiology. Blood samples were collected at baseline and every week for a period of 12 weeks and were tested for anti-CMV IgG and anti-HHV-6 IgG, CMV pp65 antigenemia, as well as CMV and HHV-6 DNA using the Polymerase Chain Reaction (PCR) method. Results: Among 46 liver transplant recipients, 17 (36.9%) developed CMV infection within 3 months after transplantation. Before transplantation, 42 (91.3%) and 41 (89.1%) recipients were seropositive for CMV and HHV-6, respectively. Fifty percent of patients were positive for CMV antigenemia, among which 73.9% became symptomatic for CMV infection. Half of the patients had positive test results for CMV PCR with a significant relationship between the CMV viral load and the development of symptomatic CMV infection (P = 0.001). Twenty-five (54.3%) patients had positive test results for HHV-6 PCR with a significant relationship between HHV-6 positivity and the development of clinical presentation (P = 0.002). The average post-transplantation time to HHV-6 and CMV activation was 19.4 ± 86.5 and 28.4 ± 60.5 days, respectively, with a linear relationship in the regression analysis. Conclusions: The HHV-6 infection, either as primary infection or reactivation, leads to an increased risk of CMV infection and symptomatic disease after liver transplantation. Activation of HHV-6 precedes the CMV activation in time.
