Abstract
The objective was to determine whether detectable levels of OP metabolites influence the relationship between BMI and cardiometabolic health. This cross-sectional study was conducted using 2227 adults from the 1999-2008 NHANES datasets. Urinary concentrations of six dialkyl phosphate metabolites were dichotomized to above and below the detection limit. Weighted multiple regression analysis was performed adjusting for confounding variables. Independent of BMI, individuals with detectable metabolites had higher diastolic blood pressure (for dimethylphosphate, diethylphosphate, and diethyldithiophosphate; P < 0.05), lower HDL (for diethyldithiophosphate; P = 0.02), and higher triglyceride (for dimethyldithiophosphate; P = 0.05) than those below detection. Contrarily, those with detectable dimethylthiophosphate had better LDL, HDL, and total cholesterol, independent of BMI. Individuals at a higher BMI range who had detectable diethylphosphate (interaction: P = 0.03) and diethylthiophosphate (interaction: P = 0.02) exhibited lower HDL, while little difference existed between OP metabolite detection statuses at lower BMIs. Similarly, individuals with high BMIs and detectable diethylphosphate had higher triglyceride than those without detectable levels, while minimal differences between diethylphosphate detection statuses were observed at lower BMIs (interaction: P = 0.02). Thus, cardiometabolic health outcome differs depending on the specific OP metabolite being examined, with higher BMIs amplifying health risk.

Abstract
Boophilus annulatus is an important one-host tick in the Mediterranean regions and Iran. It can transmit the Babesia bigemina, Babesia bovis and Anaplasma marginale to cattle. Nowadays, immunization programs by tick proteins is one of the potential methods for the control and prevention of tick infestations. Therefore, the characterization and identification of various tick proteins are necessary. Vitellogenin is a precursor of vitellin that is produced in mid gut cells and fat bodies in ticks. In this study, we characterized vitellogenin protein of B. annulatus unfed larvae using one- and two-dimensional electrophoresis and immunoblotting. In one-dimensional immunoblotting, 48, 70, 100, 130 and >250 kDa protein bands positively reacted with immune sera. In two-dimensional immunoblotting many protein spots positively reacted with immune sera. Six of them were analyzed by MALDI-TOF and MALDI-TOF- TOF mass spectrometry. The results showed that amino acid sequences of four immunogenic proteins with molecular weights of 38, 43, 85 and 97 kDa had identity to tick vitellogenin and its homologues (GP80), based on the Mascot search results. It seems that more knowledge on tick proteins including vitellogenin and their characterization could be useful for the development of anti-tick vaccines.

Abstract
Between 2002 and 2004, the standardized 28-day protocol recently developed by the World Health Organization was used to explore the efficacy of chloroquine, in the treatment of uncomplicated, Plasmodium falciparum malaria, in five sentinel sites in southern Iran. All but 14 of the 158 patients enrolled (128, 28 and two from the provinces of Sistan-Baluchestan, Hormozgan and Kerman, respectively) were successfully followed-up. The overall frequency of treatment failure by day 28 was 78.5%, with 17.4% of the patients being classed as early treatment failures, 34.7% as late clinical failures, and 26.4% as late parasitological failures. There appeared to be no significant change in the frequency of treatment failure between the 2002-2003 and 2003-2004 transmission seasons, nor any significant between-site variation in the efficacy of chloroquine. Given these observations, the replacement of chloroquine, as the first-line drug for the treatment of uncomplicated, P. falciparum malaria in Iran, was inevitable. Artesunate-sulfadoxine-pyrimethamine is now the recommended first-line treatment, with artemether-lumefantrine used for second-line treatment. The efficacies of these combination therapies are currently being evaluated and monitored.

Abstract
The Islamic Republic of Iran is in the pre-elimination phase of malaria control, but malaria epidemics are still a concern in the south of the country. This retrospective study presents the epidemiological characteristics and predisposing factors of 60 of the malaria epidemics reported in Sistan va Baluchestan province during 2005-09. A zero-truncated negative binomial model was used to investigate the relation between predictor variables and the total number of malaria cases. Malaria epidemics occurred mainly in the southern part of the province, mostly between July and October, peaking in August. Most malaria epidemics were small-scale (68.3% were < 100 cases) and short (51.7% lasted < 1 month). Plasmodium falciparum was present in 46.7% of the epidemics. An increase in the rainfall rate as well as population movements were the most significant predisposing factors. The results may help inform an epidemic investigation and reporting system as the country approaches the malaria elimination phase.

Abstract
The antimicrobial activity of thirty six novel dihydropyrimidine derivatives was evaluated against common pathogenic bacteria. Significant antimicrobial activity (MIC=32, 64 μg/ml) was observed. Escherichia coli and Pseudomonas aeruginosa as Gram-negative bacteria and Staphylococcus aureus as Gram-positive bacteria were determined to be the most susceptible pathogens in this study. The highest inhibitory activity was observed against Gram-negative microorganisms. The widest spectrum of antibacterial activity was exerted by C6 and C22. Most of the compounds had remarkable antifungal activity (MIC=32 μg/ml).

Abstract
Sweet sorghum is adapted to the hot and dry climatic conditions and its tolerance to slat is moderately. It can be used for different products such as food, feed, fiber and fuel. This study was carried out to evaluate the effects, three nitrogen treatments, and three harvesting stages on the aconitic acid, fiber and invert sugar of three sweet sorghum cultivars in the experimental station and the results showed that the effects were significant. Among nitrogen treatments, application of 100 kg ha(-1) urea at planting and 200 kg ha(-1) urea at 4 leaf stage had the highest aconitic acid (0.26%) and invert sugar (3.44%). Among sweet sorghum cultivars, IS2325 and Vespa had the highest aconitic acid (0.26%) and invert sugar (3.86%), respectively Plant harvested at 4 leaf stage had the highest aconitic acid (0.26%) and the highest invert sugar (3.85%). Rio had higher fiber content than Vespa and IS2325 and all cultivars had the highest fiber content before chilling harvesting stage. In general, since high invert sugar and high aconitic acid interfere crystallization of sugar so, it is suggested that to plant Vespa, apply urea 100 kg ha(-1) urea at planting, 100 kg ha' urea at 4 leaf stage and 100 kg ha(-1) urea at booting and harvested before chilling that had lowest aconitic acid and invert sugar. Thereby, it is recommended to plant Vespa, apply urea 100 kg ha(-1) urea at planting, 100 kg ha(-1) urea at 4 leaf stage and 100 kg ha(-1) urea at booting and harvested at 4 leaf stage that had the highest aconitic acid.

Abstract
Genetic factors, including cytokine gene polymorphisms, are potential contributors to the pathogenesis of the Graves' disease (GD). We attempted in this study to determine the association between GD and the following polymorphisms in the interleukin-1 (IL-1) family genes: IL-1alpha (-889C/T), IL-1ss (-511C/T), IL-1ss (+3962C/T), IL-1R (Pst-1 1970C/T) and IL-1RA (Mspa-I 11100C/T). We studied 107 patients with an established diagnosis of GD and 140 healthy controls. Cytokine typing was performed by the polymerase chain reaction with sequence-specific primers assay. Genotype distributions among patients were in Hardy-Weinberg equilibrium for all polymorphisms. The frequency of the IL-1alpha -889T allele was significantly higher in patients than in controls (51.9% vs. 31.6%, OR=2.33, 95% CI=1.61-3.38; p<0.0001). The IL-1RA Msp-I 11100C allele was significantly more frequent in patients than in controls (50.0% vs. 22.9%, OR=3.38, 95% CI=2.29-4.97, p<0.0001). No significant associations were found for other polymorphisms. Although the IL-1 family has well-known roles in GD pathogenesis, the contributions of their genetic variations to the disease are unclear. In this study, we documented a highly significant association between GD and polymorphism in IL-1alpha and IL-1RA genes. Further studies in other populations are necessary to confirm our results.

Abstract
We reviewed the clinical manifestations and outcome of 20 cases of neurobrocellosis out of 1375 patients with brucellosis admitted to the infectious diseases ward of a tertiary hospital in Hamedan, Islamic Republic of Iran. Of the 20 cases, 12 had meningitis (acute and subacute), 4 had meningoencephalitis, 2 had myelopathy, 1 had polyradiculopathy and 1 had meningovascular complications manifested by stroke. The most prevalent symptoms were headache (75%), vomiting and fever (50%) and unconsciousness (35%). Among 20 neurobrucellosis patients, 1 died and the other 19 recovered; 14 fully recovered and 5 patients had residual neurological deficits. In endemic areas, the disease should be ruled out in all patients who develop unexplained neurological symptoms.

Abstract
Counselling of patients with viral hepatitis is often limited to discussions about how the virus is transmitted. The aim of the present study was to document the principal concerns of patients suffering from chronic hepatitis B and C infection. The most common volunteered concerns were infecting family members (80.6%), infecting others (66.7%), side-effects of treatment (50.0%), disease progression to cirrhosis (44.4%), loss of employment (41.7%), liver transplantation (36.1%), social stigma (36.1%), change in lifestyle (33.3%), development of liver cancer (25%), costs and money (22.2%), fear of disease (5.6%) and psychological disease (5.6%). Health care providers who focus counselling efforts exclusively on viral transmission are unlikely to address other important concerns.

Abstract
An analytical cross-sectional study determined the serogroups and serotypes of Vibrio cholerae, and their antibiotic resistance rates, in the 2005 cholera epidemic in Hamadan. All 190 patients with positive stool cultures had V. cholerae serogroup O1, biotype El Tor and serotype Inaba positive. Of 60 cases selected randomly for antibiogram testing, sensitivity to norfloxacin, ciprofloxacin, kanamycin, amikacin, tetracycline and doxycycline was 97%, 92%, 88%, 85%, 77% and 67% respectively. Resistance to furazolidone, trimethoprim-sulfamethoxazole and erythromycin was 100%, 98% and 62% respectively. Comparison with the results of the 1998 epidemic suggests a worrying increase in the resistance of V. cholerae to erythromycin, doxycycline and ciprofloxacin.

Abstract
Principal component and cluster analyses were used to evaluate the pattern of morphological variation in 122 accessions of Aegilops crassa for 14 quantitative characters. With the principal component analysis, the first five principal components with eigenvalues more than 1 contributed 69.5% of the variability amongst accessions, whereas PC6 to PC14 were less than unity. Plant height, stem diameter, spike length and number of spikelets per spike were the most important characters in the first principal component. The germplasm was grouped into five clusters using cluster analysis. Although each cluster had some specific characteristics of its own, but clusters were not clearly separated when plotted by the first two principal components. Mahalanobis distances (D2) determined that plant height, stem diameter, spike length, number of spikelets per spike, node width, seed length, seed width and flowering date characters as the most important characters in differentiating the accessions. The morphological variation of Aegilops crassa accessions obtained in this study provides useful information for the future collection and makes these genetic resources more accessible to breeders.

Abstract
We determined the seroprevalence of hepatitis B in Nahavand in a sample of 1824 subjects > 5 years in 2002. Face-to-face interviews were conducted and blood samples taken. The association between risk factor and hepatitis B was assessed using logistic regression. The prevalence of HBsAg positive cases was 2.3%, and HBcAb and HBsAb were isolated in 7.8% and 11.6% of the participants respectively; 11.9% were positive for both HBcAb and HBsAb. History of surgery and imprisonment were the major risk factors for infection with odds ratios of 2.14 (95% CI: 1.22-3.05) and 3.57 (95% CI: 1.68-5.4) respectively.

Abstract
We examined the therapeutic effects of albendazole compared to metronidazole in 120 patients with giardiasis in Hamdan. Patients were randomized to receive albendazole (400 mg, once daily for 5 days) or metronidazole (250 mg, 3 times a day for 5 days). Demographic data of the patients, results of stool examination for Giardia trophozoites before and after treatment, and drug side-effects were recorded. After treatment 6 (10.0%) of the albendazole group had trophozoites compared with 14 (23.3%) of metronidazole group (P < 0.05). Patients in the albendazole group had fewer side-effects while 43.3% of the metronidazole group experienced a metallic taste and 35.0% experienced loss of appetite. Albendazole is an easy, safe and effective treatment for giardiasis.

Abstract
OBJECTIVE Brucellosis is a zoonosis of both public health and economic significance in most developing countries. Polymorphisms in Toll-like receptor-4 (TLR4) have been reported to be associated with a blunted immune response to microbial pathogens. Information regarding any association between genetic variation of TLR4 and susceptibility to brucellosis is not available in the literatures. The main purpose of this research is to evaluate the role of polymorphic alleles of TLR4 gene in susceptibility to brucellosis. MATERIALS AND METHODS In this case-control study, 198 patients with brucellosis and 111 healthy volunteers matched for sex, age and geographic area were evaluated by genotyping for polymorphism in TLR4 gene (Asp299Gly) using amplification refractory mutation system (ARMS)-PCR method. RESULTS Allele 896G was more prevalent in patients with brucellosis compared to healthy controls (33.6% vs. 20.7%, P=0.000003). Also the frequency of G allele of TLR4 gene was significantly higher in male patients with brucellosis compared to the same sex in control group (36% vs. 21.7%, P=0.00005). Multiple logistic regression analysis demonstrated that male patients heterozygous at allele G gene had a significantly higher risk for brucellosis with an odds ratio of OR 2.89, 95% CI: 1.79-4.69, P<0.0001). CONCLUSION This study is the first to show an association between genetic polymorphism in TLR4 gene and susceptibility to brucellosis.

Abstract
A study was carried out to determine the association between unintended pregnancy and pre- and postpartum depression in 163 women in Kermanshah city, Islamic Republic of Iran. Using the self-administered Beck Depression Inventory for educated women and a special interview for illiterate women, 105 intended and 58 unintended pregnancies were studied. Of the 58 women with unintended pregnancy, 43% reported attempting to abort the fetus. Depression at 37 weeks' gestation was slightly higher in the unintended than the intended pregnancy group (53.4% versus 41.0%; relative risk = 1.3) and depression 10 days postpartum was much higher in the unintended group (48.7% versus 25.6%; relative risk = 1.9). Screening for depression is recommended for pregnant women with unintended pregnancy.
