A one-pot conversion of tertiary thioamides to S-2-oxo thioesters is reported. Hence, tertiary thioamides were reacted with α-halo ketones or acids under solvent-free conditions to produce the corresponding oxo-thioesters in good to excellent yields.

Introduction: Design and implementation of screening programs in each country must be based on epidemiological data. Despite the relatively high incidence of CRC, there is no nationwide comprehensive program for screening in Iran. This study was designed to investigate national CRC data and help to determine guidelines for screening. Methods: Incidence data used in this study were obtained from Iranian annual of National Cancer Registration report. Age standardized rates (ASR)were calculated using world standard population and were categorized by age, sex, anatomic subsite and morphology of tumor. Data were analyzed using SPSS.V.13 and Open Source Epidemiologic Statistics for Public Health software (OpenEpi v.2.3.1). Results: A quarter of cases were less than 50 years of age. The majority of tumors were detected in the colon. The overall ASR in the four years period was 38.0 per 100000 and was higher for men compared women (P<0.05). Incidence rate of colorectal cancer increased with age. Conclusion: Results of present study indicated that incidence of colorectal cancer is relatively high in Iran. Incidence of CRC in people under 50 years and in rectum were reported higher than other countries that related etiologic factors should be investigate in further studies. According to the increasing of ASR after age 50 years, it seems that onset of screening at age 50 would be appropriate.
What Explains a Negotiated Outcome for Social Policy Shareholder Resolutions?
Miguel Rojas,Bouchra M’Zali,Marie-France Turcotte,Philip Merrigan KINFORMS 2012 Management Review Vol.7 No.1
This article analyzes the outcome of social policy shareholder resolutions. It does so by focusing on many types of resolution withdrawals sponsored by various types of filers. The paper shows that some characteristics of the resolutions themselves as well as those of the targeted firms play a role in the likelihood of a negotiated settlement between filer and management. Some issues, such as board diversity or equal employment, seem more conducive to a negotiated settlement of the resolutions filed. Others, such as energy and environment, against our expectations, do not seem to tilt the negotiation in favour of filers. The percentage of votes received by the resolution the year before also increases the probability of a favourable settlement for filers. Moreover, when introduced into the regressions, this variable overrides many other variables’ influence in the outcome.
Technical Efficiency Analysis of Container Terminals in Middle Eastern Region

Despite an increasing number of studies on the efficiency of container terminals, their focus has mostly been on advanced and emerging markets. There are limited studies on container terminals in developing countries such as those of the Middle Eastern region, which are located in a critical geographic position in the international maritime route between the East and the West. Information on their potential for development relative to other terminals worldwide is thus not readily available. This study aims to evaluate the technical efficiency of 19 container terminals in the Middle Eastern region. The DEA approach is used to measure technical efficiency, and slack variable analysis identifies potential areas of improvement for inefficient terminals. The results show that the Jebel Ali, Salalah and Beirut container terminals are the most efficient terminals in the region, and that the least efficient is the terminal in Aden. The results provide valuable information for terminal managers, helping to develop resource utilisation for steady development in operational efficiency.
Burden of Hepatocellular Carcinoma in Asia

Hepatocellular carcinoma (HCC), the sixth most prevalent cancer worldwide, continues to have high prevalence in many countries of Asia. The main challenge is the high prevalence of chronic hepatitis and aflatoxin, for example in China. HBV vaccination should be the major preventive tactic in Asian countries. The burden of HCC is low in Iran because most cases are due to HBV and this infection was less common. Although in Iran, a mass vaccination program started in 1993, its impact on decreasing the burden of HCC due to HBV can only be expected in future decades.

Dissection of genotype-by-environment interaction (GEI) effects has a key role in identifying stable high-yielding genotypes across various environments before commercial release. This study sought to assess the GEI effect and to identify superior barley genotypes using 32 parametric and non-parametric stability statistics. Eighteen new promising genotypes along with one improved cultivar (as check) were evaluated across ten environments during the 2019–2021 cropping seasons in the warm climate of Iran. The AMMI analysis of variance indicated that genotype, environment, and GEI effects were significant for grain yield. Furthermore, partitioning of the GEI effect showed that the first six interaction principal components (IPCA1–IPCA6) were highly significant. Multivariate analyses classified all measured statistics into five groups based on the dynamic and static concepts of stability. Among the stability statistics, HMGV, RPGV, HMRPGV, CV, NP(2), NP(3), NP(4), KR, S(3), and S(6) showed a dynamic concept of stability. Based on all methods, genotypes G2, G3, G9, G11, G14, and G17 were identified as stable high-yielding genotypes. In general, based on all of the used approaches, G9 and G11 were identified as the best genotypes for cultivation in the warm regions of Iran; hence, these genotypes can be considered for commercial release.

Previous studies suggest that 4-aryl-4H-chromenes are potent apoptosis-inducing agents in various cancer cell lines. In this study, anti-proliferative and apoptotic effects of the derivatives from 4-aryl-4H-chromene family were investigated in the human leukemia K562 cells using [3-(4,5)-dimethyl-2-thiazolyl]-2,5-diphenyl-2H-tetrazolium bromide (MTT) growth inhibition assay. 3-NC was more active among these compounds with IC50 of 65 nM and was selected for further studies. Apoptosis, as the mechanism of cell death, was investigated morphologically by Hoechst 33258 staining, cell surface expression assay of phosphatidylserine by Annexin V/PI technique,caspase-3 activation assay, as well as the formation of DNA ladder. The K562 cells underwent apoptosis upon a single dose (at IC50 value) of the compound, and also increased caspase-3 activity by more than 2.3-fold, following a 72 h treatment. Caspase-9 was also activated which could be detected 48 hours post-treatment. Furthermore, Western blot analysis revealed that the treatment with the compound down-regulated the expression of certain IAP protein, including survivin. These data further suggest that these derivatives from 4-aryl-4H-chromene may provide a novel therapeutic approach for the treatment of leukemia.

Cholangitis is relatively uncommon but associated mortality is high due to the predisposition in people with underlying disease. For this recognition of contributing risk factors is necessary. Therefore, the present descriptive-analytical cross-sectional survey was designed to determine contributing risk factors for post-ERCP cholangitis in patients with pancreatic cancer. From 2005 to 2010, 110 consecutive cases of pancreatic cancer attending to a tertiary referral centre (Taleghani Hospital), Tehran, Iran were recruited. The patients all underwent stenting via endoscopic retrograde cholangiopancreatography (ERCP). On univariate analysis, a metallic stent type (95% confidence interval (CI) 1.025-11.34, P=0.037), having no jaundice (1.44-2.22, P=0.009), having no pain (1.32-1.91, P=0.026), a history of prior ERCP (1.16-10.37, P=0.020), and having a proximal biliary stone (1.002-5.93, P=0.046) were related to cholangitis. However on multivariate analysis, none of these factors were found to be contributing risk factors. Cholangitis is avoidable with adequate biliary drainage. Because success rates are higher and complication rates lower for endoscopists performing large volumes of ERCP, performance of the procedure should be concentrated as much as possible in institutions with endoscopists having adequate experience. Patients with a high risk for complications may be best served by referral to an advanced center.
