Prevalence of Induced Abortion in Iran: A Comparison of Two Indirect Estimation Techniques.

Context: Surveys that use direct questions to ascertain women's history of induced abortion tend to underestimate abortion prevalence, especially in such contexts as Iran where the procedure is legally restricted and highly stigmatized. No previous study has compared two indirect techniques for estimating abortion prevalence.

Methods: A sample of 708 married women were recruited from one public hospital in Tehran between August and December 2013.

Evaluation of Mental Workload among ICU Ward's Nurses.

Background: High level of workload has been identified among stressors of nurses in intensive care units (ICUs). The present study investigated nursing workload and identified its influencing perfor-mance obstacles in ICUs.

Methods: This cross-sectional study was conducted, in 2013, on 81 nurses working in ICUs in Imam Khomeini Hospital in Tehran, Iran.

RNA-mediated gene silencing in Candida albicans: inhibition of hyphae formation by use of RNAi technology.

The introduction of RNA silencing machinery in fungi has led to the promising application of RNAi methodology to knock down essential vital factor or virulence factor genes in the microorganisms. Efg1p is required for development of a true hyphal growth form which is known to be essential for interactions with human host cells and for the yeast's pathogenesis. In this paper, we describe the development of a system for presenting and studying the RNAi function on the EFG1 gene in C.

The positive association between number of children and obesity in Iranian women and men: results from the National Health Survey.

Background: To date, few studies have assessed the association between the number of children and obesity in couples. We aimed to investigate this association in men and women aged 20-75 years.

Methods: Data from the National Health Survey were considered in this investigation.

dupA as a risk determinant in Helicobacter pylori infection.

The Helicobacter pylori duodenal ulcer promoting (dupA) gene has been previously described as a risk marker for duodenal ulcer (DU) development and a protective factor against gastric cancer (GC). Recent studies which have assessed the application of dupA in the prediction of clinical outcomes have been controversial. In the current study, the association of dupA with the clinical outcomes and histopathological changes following H.

Sociodemographic and smoking associated with obesity in adult women in Iran: results from the National Health Survey.

Background: There is no study that had a sample size sufficient to study the association between sociodemographic and smoking with obesity in Iran. The goal was to investigate these associations in the Iranian women.

Methods: Multivariate statistical techniques included 14 176 women between 20 and 69 years of age.

Determination of gelatinase A using a modified indirect hemagglutination assay in human prostate cancer screening and assessment of its correlation with prostate-specific antigen parameters.

Background: Prostate cancer is the most common malignancy affecting men and is a major cause of cancer death. There are increasing data on novel tumor markers, such as gelatinase A, which play a key role in tissue invasion and metastasis.

Objectives: We designed a study to evaluate total gelatinase A content using a simple and applicable Indirect hemagglutination (IHA) test in harmony with gelatinase A activity in serum samples as compared with prostate-specifc antigen (PSA) parameters.
