5-fluorouracil (5-FU) is one of the major components of many standard regimens for chemotherapy of colorectal cancer (CRC) and some other malignancies. Given the known relationship between thymidylate synthase (TS) and methylenetetrahydrofolate reductase (MTHFR) activity and 5-FU metabolism, this study investigated the impact of selected functional polymorphisms of the TS and MTHFR genes on chemotherapy resistance in 5 human CRC cell lines. HCT116, SW1116, HT29/219, LS180, and Caco-2 CRC cells were cultured as monolayer and their chemosensitivity to 5-FU, oxaliplatin, and irinotecan was determined by MTT assay...

Breast cancer imposes a considerable amount of cancer-related mortality and morbidity among women worldwide. Many efforts are in progress to reduce the disease burden and amongst the bacterial-based products received considerable attention as potential anti-cancer drugs. In the present study, the effect of recombinant pro-inflammatory outer membrane protein (HopH) of Helicobacter pylori on the angiogenic factor and tumor development in metastatic breast cancer model was evaluated. The HopH gene was cloned into Pet28a vector, induced by IPTG and expressed and purified by Ni-NTA affinity chromatography...

Hepatotoxicity is one of the clinically adverse effects of ecstasy (3, 4-methylenedioxymethamphetamine; MDMA) consumption. The detoxification tissue, liver, plays a central role in maintaining circulating levels of glucose and lipid. Hypoglycemia and hypotriglyceridemia have been reported due to ecstasy abuse. Ghrelin is a 28-amino-acid peptide secreted predominantly from the stomach. It has been demonstrated that ghrelin has hepatoprotective effects and is able to increase blood glucose concentration. In the current study, we explored the effect of hepatotoxic dose of MDMA and therapeutic use of exogenous ghrelin on the serum levels of glucose and lipids in four groups of rats...

Complications of hiatal hernia are potentially lethal, and surgical intervention is necessary. This matter is more important in cases that have ambiguous symptoms and are diagnosed with a delay. Such patients may experience life-threatening course and events. Accordingly, in this report, a 23-year-old male patient with unusual findings is presented. A 23-year-old male patient with acute dyspnea and fever was admitted in infectious disease ward with diagnosis of empyema according to chest radiography and CT-scan findings (Figures 1 and 2)...

Hydatid cysts in humans usually located in the liver or lungs primarily and some case in the other organs. Sometimes, because the trauma or medical manipulating, the cyst may be rupture and protoscoleces spillage resulted in secondary hydatid cyst. Primary dissemination of cyst to multiple organs is a rare phenomenon. Herein, we reported a 14-year-old teenage female patient with symptoms of abdominal pain with an unusual ultrasonographic and computed tomographic presentation mimicking polycystic ovarian syndrome PCOS...

Hepatocellular carcinoma (HCC) is not uncommon neoplasm, and its occurrences with coronary artery disease (CAD) is more confronted by cardiac surgeon today. In most cases, when the HCC is detected, it has invaded to regional or distant sites. The most frequent location of HCC metastasis includes pulmonary system, musculoskeletal, lymphatic system, and central nervous system. Indeed, intra-atrial metastasis is a rare phenomenon and associated with poor outcome. We report a case of CAD with known HCC that referred for CABG before scheduling for hepatic tumor management...

Bilateral occlusion of internal carotid arteries is a rare condition usually associated with severe neurological symptoms. It is very uncommon finding among patients with ischemic stroke. In this article, we report a rare case of bilateral occlusion of internal carotid artery who presented with mild reversible neurological symptoms. Angiographic evaluation of her cerebral vasculature revealed no flow across the both cervical internal carotid arteries, but a run off through both posterior communicating arteries from the vertebrobasilar system...

To determine the prevalence of allergic rhinitis (AR) among adult residents and investigate whether second-hand tobacco smoke (SHS) is correlated with AR as one of the global health problems and one of the most common respiratory disorders reducing the quality of life. A telephone interview survey was conducted by calling 16500 randomly selected telephone numbers from 22 regional telecommunications of Tehran (capital city of Iran) in 2010. A modified European Community Respiratory Health Survey (ECRHS) questionnaire was completed for adults aged between 20 to 44-year-old...

Published studies on dermatological emergencies are limited in the literature. To our knowledge, no study has previously explored this subject in Iran. Our aim was to ascertain the characteristics of patients visiting the dermatologic emergency (DE) unit of a university skin hospital in Tehran, Iran. We studied the files of all the patients seen in the DE unit over a 3-month period, collecting data on age, sex, referral mode, duration of consultation, status (true emergency or non-emergency), and diagnosis...

Accurate measurement of Mitral Valve Area (MVA) is essential to determining the Mitral Stenosis (MS) severity and to achieving the best management strategies for this disease. The goal of the present study is to compare mitral valve area (MVA) measurement by Continuity Equation (CE) and Pressure Half-Time (PHT) methods with that of 2D-Planimetry (PL) in patients with moderate to severe mitral stenosis (MS). This comparison also was performed in subgroups of patients with significant Aortic Insufficiency (AI), Mitral Regurgitation (MR) and Atrial Fibrillation (AF)...

One of the important reasons for accidents is sleepiness.With this description, the sleep disorders are associated with health and mortality, and not only affect the person but also the family and the whole society. Aim of this study was assessing of relationship between Sleep Quality, Obstructive sleep Apnea and Sleepiness during day with related factors in professional drivers. This was a cross-sectional study measuring correlation between sleep quality questionnaire (Pittsburgh Sleep Quality Index or PSQI), Epworth Sleepiness Scale (ESS) and Stop Bang questionnaire (STOP BANG)...

The purpose of this study was to determine the effect of vestibular rehabilitation therapy program on the sensory organization of deaf children with bilateral vestibular dysfunction. This cross-sectional and analytic study was conducted on 24 students between the age of 7 and 12 years (6 girls and 18 boys) with the profound sensorineural hearing loss (PTA>90 dB). They were assessed through the balance subtest in Bruininks-Oseretsky test of motor proficiency (BOTMP). For children which the total score of the balance subtest was 3 standard deviation lower than their peers with typical development, vestibular function testing was completed pre-intervention...

Juvenile idiopathic arthritis (JIA) is a clinically heterogeneous cluster of complex diseases, in which both the genetic and environmental factors seem to play a role in the development of the disease. The current study aims to assess the association of programmed cell death 1 (PDCD1, also called PD-1) gene variants with JIA vulnerability in Iranian population. In this case-control association study, we investigated a group of 50 Iranian patients with JIA in comparison with 202 healthy controls and evaluated the frequency of alleles, genotypes, and haplotypes of PDCD1 single-nucleotide polymorphisms (SNPs), comprising PD-1...

This study has been conducted to evaluate the allele, genotype and haplotype frequencies of the polymorphic gene coding TGF-β in recurrent aphthous stomatitis (RAS). TGF-β gene typing was done by polymerase chain reaction with sequence-specific primers (PCR-SSP) assay. Allele frequencies were estimated by direct gene counting. C allele at codon 25 was significantly increased, while G allele at this position was significantly decreased in patients compared to the controls. A significantly higher frequency of CG genotype at codon 25 was found in control group...
