BACKGROUND To calculate a pooled estimate of relative risk (RR) of lung cancer associated with exposure to passive smoking in never smoking women exposed to smoking spouses. This study is an updated meta-analysis that also assesses the differences between estimated risks according to continent and study type using meta-regression. METHODS From a total of(More)
OBJECTIVES To find whether polymorphisms of methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C are risk factors for diabetic nephropathy (DN) among type 2 diabetes mellitus (T2DM) patients from Western Iran. DESIGN AND METHODS The MTHFR polymorphisms were detected in 72 microalbuminuric, 68 macroalbuminuric and 72 normoalbuinuric T2DM patients(More)
BACKGROUND AND OBJECTIVE Acinetobacter baumannii is an aerobic non-motile Gram-negative bacterial pathogen that is resistant to most antibiotics. Carbapenems are the most common antibiotics for the treatment of infections caused by this pathogen. Mechanisms of antibiotic-resistance in A. baumannii are mainly mediated by efflux pumps-lactamases. The aim of(More)
Among numerous artificial intelligence approaches, k-Nearest Neighbor algorithms, genetic algorithms, and artificial neural networks are considered as the most common and effective methods in classification problems in numerous studies. In the present study, the results of the implementation of a novel hybrid feature selection-classification model using the(More)
Intentional self-poisoning that is widely used all over the world is one of the most common methods of suicide. This study aim was to determine the rate of attempted intentional self-poisoning and to identify high risk persons in the west of Iran (Kermanshah). A total of 3138 people (1279 M and 1859 F) studied. The average annual rate of suicide in(More)
BACKGROUND Basal and squamous cell carcinoma (BCC and SCC) are the most common skin cancers worldwide and distinction between the two may sometimes be very difficult in routine histopathology. The present study was aimed to evaluate a reliable diagnostic method for these cancers based on immunohistochemistry (IHC). MATERIALS AND METHODS IHC was used with(More)
BACKGROUND Selective serotonin reuptake inhibitors (SSRIs) are common treatments for patients with major depressive disorder (MDD). However, adverse effects of SSRIs on sexual function are common in the treatment of patients with MDD. There is a discrepancy in the reported frequency of SSRI-induced sexual dysfunction. On the other hand, there is also less(More)
AIM To assess trends in admissions of patients with heart failure (HF) to all hospitals in Australia between 1996-1997 and 2003-2004. METHODS AND RESULTS We carried out a retrospective analysis of the official population-based National Hospital Morbidity Data in Australia. Although the absolute number of separations with a principal diagnosis of HF(More)
Periodontitis is an infectious disease involving specific bacteria and viruses. Herpesviruses believed to play roles in it. The present study examines the presence of Epstein-Barr virus (EBV) and cytomegalovirus (CMV) in subgingival and supragingival plaque of 61 patients with chronic periodontitis and 40 healthy controls. A nested polymerase chain reaction(More)
In this paper, the effect of pneumatic circuit design on the input-output behavior of PWM-driven servo-pneumatic systems is investigated and their control performances are improved using linear controllers instead of complex and costly nonlinear ones. Generally, servo-pneumatic systems are well known for their nonlinear behavior. However, PWM-driven(More)
