BackgroundThere are little data on the prevalence of serological markers of hepatitis B and hepatitis C viruses in pregnant women in Iran.ObjectivesThis study was designed to determine the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection among pregnant women in Lorestan, west of Iran.Patients and MethodsSerum samples of 827 pregnant women who lived in rural (36.8%) and urban areas (63.2%) of Lorestan were collected during 2007-2008. Data were obtained through questionnaires. Samples were first screened for anti-HCV and anti-HBc by ELISA. Those who were positive for anti-HBc were tested for HBsAg.ResultsAnti-HBc was found in 28 of 827 pregnant women (overall prevalence, 3.4%; 14 of 523 in urban areas, 2.7%; 14 of 304 in rural areas, 4.6%). Of the 28 positive samples, 6(0.7%) were positive for HBs-Ag. Only 2 samples (0.2%) were anti-HCV-positive.ConclusionsThese results underscore the need for prenatal screening for HBV infection in pregnant women and treatment of newborns from HBsAg-positive mothers.More studies are needed to identify risk factors of HCV infection and highlight the importance of HCV screening and treatment programs.

Parasite strain characterization is essential for the establishment of a prevention and control strategy in any endemic area. The aim of this study was to characterize different Echinococcus granulosus isolates from Iran by using DNA sequences of the mitochondrial 12S rRNA gene. Thirty livers and lungs of cattle, sheep and goats naturally infected with E. granulosus were collected from abattoirs in northern and western Iran between June and October 2007. These samples yielded 18 fertile cysts which we used for the genetic work. We designed and tested two new primer pairs which specifically amplify portions of the mitochondrial 12S rRNA gene of the two strains (G1 and G6) of E. granulosus known to occur in Iran. One primer pair amplified a fragment of 259 base pairs (bp) from only the G1 strain. The second pair amplified a fragment of 676 bp from the G6 strain. The G1 genotype was identified in all fertile cyst samples, in agreement with previous studies in Iran. Ten of our samples and a single reference sample of the G6 strain were sequenced and compared with the G1 and G6 sequences deposited in GenBank.

: Curcumin is one of the important natural compounds that is extracted from turmeric. This compound and its derivatives have numerous biological properties, including antioxidant, anticancer, anti-inflammatory, antimicrobial and healing effects. Extensive research in various fields has been conducted on turmeric as it is widely used as a food additive. The significant antifungal activity is one of the major effects of curcumin. In this paper, recent studies on the effects of different forms of curcumin drug on the candidiasis were systematically examined and discussed. The data in this study were extracted from the articles and reports published in the Web of Science, Google Scholar, PubMed, and Scopus databases. After the preliminary investigation, relevant reports were selected and classified based on the incorporated formulation and purpose of the study. After a systematic discussion of the data, it was found that the use of medicinal forms based on nanoparticles can increase the absorption and target the controlled release of curcumin with a more effective role compared to other formulations. Consequently, it can be concluded that new methods of modern medicine can be employed to increase the efficacy of natural pharmaceutical compounds used in the past. In this regard, the present study analyzed the effect of curcumin against various Candida infections using the recent data. It was found that applying a combination of drug formulation or the formulation of curcumin and its derivatives can be an effective strategy to overcome the medicine resistance in fungal infections, especially candidiasis.
