Abstract
The use of radiopharmaceuticals has gained a special place in the diagnosis and treatment of cancers and evaluation of the function of different organs of the body. In this study, the absorbed dose distribution of organs after injection of 188Re-Mu-9 has been investigated using MIRD method and MCNP-4C simulation code. The 188Re-Mu-9 labeled was injected the mouse body and the amount of 188Re-labeled accumulation was evaluated after 1, 4 and 2 4 h. Having a map of the distribution of radiopharmaceutical activity in the animal body, it is possible to convert it into a human model to obtain the internal dose received by 188Re-Mu-9 injection using the MIRD calculation method and the MCNP simulation code. According to the results of the study, the animal/human model can be acceptable method for dose estimation of antibody-based radiopharmaceuticals.

Abstract
Avian infectious bronchitis virus (IBV) and avian pathogenic Escherichia coli (APEC) are two important respiratory pathogens in the chicken. The co-infection can lead to chronic complications and considerable economic losses in the poultry industry worldwide. In the present study, we compared differential transcriptional profiles in the trachea tissue of three infected groups (IBV, APEC, and co-infection) with the control group to investigate transcriptome profile changes at the early stage of the infection. After the challenge of SPF chickens with IBV IS-1494 like (GI-23) and APEC, serotype O78: K80, or co-infection, the trachea tissue was used for RNA extraction, and changes in the transcriptome were investigated by Illumina RNA-seq technique. Up-regulated and down-regulated differentially expressed genes (DEGs) in the transcriptome of each group's trachea were identified. Gene ontology category, KEGG pathway, and gene interaction networks (STRING analysis) were analyzed to identify relationships among differentially expressed genes. In general, the numbers of up-regulated genes were higher than of down-regulated genes. In the co-infection group, a more severe immune response and macrophage infiltration occurred; an important cluster of pathway signaling in this group's up-regulated genes was an apoptotic cluster, cytokine-mediated signaling cluster, and the PAMPs recognizing cluster. This is the first study to provide a general overview of transcriptome changes in the trachea at the early stage of infection with these pathogens. Keywords: avian infectious bronchitis virus; avian pathogenic E. coli; transcriptome; RNA-Seq.

Abstract
INTRODUCTION Immune checkpoint inhibitors (ICI), such as anti-PD-1 agents, have become part of the standard of care treatment of advanced non-small cell lung cancer (NSCLC). Predictive biomarkers are needed to identify patients that benefit from anti-PD-1 treatments. Tumor infiltrating lymphocytes (TILs) and PD-L1 are major players in the ICI mechanism of action. In this study, we assess the impact of real-world clinicopathological variables, including TILs and PD-L1, on anti-PD-1 efficacy. METHODS We performed a monocenter retrospective study in advanced NSCLC treated with nivolumab or pembrolizumab between January 2015 and February 2019. The impact of baseline clinical and pathological variables was assessed by univariate and multivariate models. TILs, defined as CD8+T-cells, and PD-L1 were scored in tumor and stroma, and correlated with progression free survival (PFS) and overall survival (OS). RESULTS We included 366 patients of whom 141 were assessed for tumor and stromal TILs. The median follow-up time was 487 days. In the whole cohort, PFS was associated with high tumor PD-L1, high albumin and good performance. OS was associated with low LDH, high albumin, good performance and 'first-line treatment'. In the TILs subcohort, stromal TILs had the strongest impact on PFS and OS. Stromal TILs were a stronger marker for PFS and OS than tumoral TILs, tumoral PD-L1 or stromal PD-L1. Remaining factors for PFS and OS were albumin and albumin with LDH, respectively. CONCLUSIONS This real-world study on clinicopathological features shows that stromal CD8 + TILs were the strongest predictor for PFS and OS in patients with advanced NSCLC on anti-PD-1 therapy. Other predictors for PFS and OS included albumin and albumin together with LDH, respectively. This study highlights the pivotal role of the stromal compartment in the mechanisms of action of ICI, and the need for further studies aiming to overcome this stromal firewall.

Abstract
The purpose of this study was to summarize the currently published cases of clear cell odontogenic carcinoma (CCOC). The PubMed and Springer databases were used to collect available reports, searching for 'clear cell odontogenic carcinoma', 'CCOC', or 'clear cell ameloblastoma'. The search resulted in 75 reports detailing 107 cases between 1985 and 2018. Clinically the tumor manifests as a swelling in the posterior mandible (n=46), anterior mandible (n=33), and maxilla (n=28). Radiological analysis of 85 cases typically showed a poorly defined expansive radiolucency (n=83). Of the 70 patients with symptoms reported, 44 specified a swelling, 11 tooth mobility, seven gingival/periodontal issues, five numbness, and three decreased jaw opening. One patient presented with a neck mass. The duration of symptoms prior to seeking care was specified for 52 patients: 2 months to 1 year for 34 patients, 1-2 years for seven, 2-4 years for two, 4-7 years for six, and 7-12 years for three. The incidence of recurrence appeared to be 38 of the 88 cases where recurrence was reported. CCOC can be distinguished from other oral cancers by its distinctive histology and immunohistochemical characteristics and less aggressive behavior. Currently, treatment should be early and aggressive resection with clear surgical margins and long-term follow-up. The overall goal is to collect a cohort of patients.

Abstract
Background: During decades, all improvements and developments in radiation therapy technologies have been focused on its main goal: maximize the dose in the tumor and minimize it in surrounding normal tissues. Recently, scientists have some approaches to nanoparticles, especially gold nanoparticles (GNPs), for dose localization. Purpose: Herein, the effect of GNPs in combination with electron brachytherapy in a model of eye tumor has been investigated. Materials and methods: Monte Carlo simulation was utilized and a complete anatomical model of the eye, a tumor with 5 mm thick, and a type of Ruthenium-106 beta emitter ophthalmic plaque were simulated. Simulation results have been validated by a Plexiglas eye phantom and film dosimetry, experimentally. Results: The results showed using GNPs causes the dose amplification in 2 mm from the plaque surface which the higher concentration has the higher enhancement. At more distances, Dose Enhancement Factors (DEFs) have the negative amounts, so that total delivered dose to the tumor has decreased with increasing of Au concentrations and the dose of organ at risk like sclera has increased. Conclusion: Therefore, using of GNPs along with a 106Ru/106Rh ocular plaque, as an electron emitter source, is a good choice only for superficial lesions, and it is not recommended for deeper tumors due to the parameters of radiation treatment and delivered dose to the tissues.

Abstract
NiO nanoparticles in high purity, 15 ± 0.5 nm in size, were prepared via solid-state microwave irradiation. The [Ni(NH3)6](NO3)2 complex as a novel source was decomposed in the presence of microwave irradiation for a short time (10 min). The present method is facile, safe, and low-cost. This method exhibits other advantages; there is no need of a solvent, fuel, surfactant, expensive material, or complex instrument. Synthesised NiO nanoparticles were determined by various analyses. Also, for the first time, NiO nanoparticle effects on biochemical factors in soybean were investigated. Seeds of soybean were grown in the Murashige and Skoog agar medium containing different concentrations of NiO nanoparticles (0, 200, and 400 mg/L) for 21 days under growth chamber conditions. Estimates of malondialdehyde, hydrogen peroxide contents, and antioxidant enzymes (catalase and ascorbate peroxidase) under treatment of NiO nanoparticles were assayed. The result showed that by significantly increasing the concentration of NiO nanoparticles, the activity of catalase and ascorbate peroxidase enzymes was enhanced. Malondialdehyde and hydrogen peroxide contents significantly increased in the presence of NiO nanoparticles. In this study, the increasing activity of catalase and ascorbate peroxidase was not enough for radical oxygen species detoxification.

Abstract
The interaction between nanoparticles and plants is inevitable. In this study, the effect of different concentrations of ZnO nanoparticles synthesised using olive extract on the soybean was studied. The soybean seeds were cultured in a Hoagland medium containing agar which was treated different concentrations (0, 200 and 400 ppm) of ZnO nanoparticles. After 21 days, the plants were harvested and the parameters of proline, anthocyanin, malondialdehyde (MDA), hydrogen peroxide (H2O2), chlorophyll and carotenoid contents and phenylalanine ammonia-lyase (PAL) and catalase (CAT) activity in soybeans (Glycine max) were measured. The results showed that the levels of chlorophyll a and b and carotenoid at concentrations of 200 and 400 ppm in comparison with control decreased, while carotenoid content at 200 ppm concentration at a concentration of 400 ppm was not significant. The level of anthocyanin and PAL activity increased with increasing concentration of nanoparticles, while proline content decreased. By increasing the concentration of ZnO nanoparticles, the content of MDA and hydrogen peroxide increased compared to control but CAT activity did not change significantly. This research suggests that ZnO nanoparticles synthesised using olive extract in soybean plants may be toxic by reactive oxygen species production.

Abstract
SummaryEndothelial cells (ECs) synthesize and release von Willebrand factor (vWf) either constitutively or from Weibel-Palade bodies by a regulated pathway. Although stimulated release of vWf from ECs occurs following exposure to thrombin, histamine, interleukin, tissue necrosis factor and fibrin in vitro, these agents are unlikely to be present in physiologically relevant concentrations during the initial stages of primary hemostasis. Alternatively, agents known to be released from the dense granules of activated platelets at the sites of vascular injury may provide the initial physiological stimuli for vWf release from ECs in vivo. We have examined the effects of the platelet secretagogues ADP, AMP, ATP and serotonin on the release of vWf from ECs and demonstrated enhanced release in all cases. The extent and time at which optimum vWf release was observed depended on the agonist and its concentration. At 3 nM, optimum release occurred after 4 hours with ADP (330 %/ml) or 1 h with AMP (153%/ml) or ATP (450%/ml). At 30 nM, optimum release was seen after 1 hour with ADP (315 %/ml) or AMP (595%/ml) and after 15 min with ATP (938%/ml). With serotonin, optimal release was seen by 30 min at 0.3 μM (1034%/ml) and after 1 h at 1 pM (745%/ml) although the response after 15 min was nearly equivalent (667%/ml). The doses giving 50% of maximal response (ED50) after 1 h were 6.5 nM (ADP), 15.2 nM (AMP) and 2.4 nM (ATP) and 20 nM for ATP or 75 nM for serotonin after 15 or 30 min respectively. ADP also enhanced PGI2 release from ECs in a dose- and time-dependent manner. These observations support a mechanism whereby activated platelets, which interact with and bind to ECs or subendothelium and release adenine nucleotides or serotonin from platelet dense granules, could stimulate the release of vWf from adjacent ECs thereby enhancing EC-platelet interactions and facilitating primary hemostasis.

Abstract
Green synthesis of nanoparticles is superior to physical and chemical methods as it is environment-friendly and cost-effective. The present study was carried out for inducing nanoparticles synthesis by zinc nitrate in the leaves extracts of olive. Further leaves extracts were evaluated for antiradical scavenging activity by 1, 1-diphenyl-2-picryl-hydrazyl assay. Morphological and structural properties of the synthesised ZnO nanoparticles have been characterised using UV-Vis spectrophotometer, FTIR, TEM, XRD and dynamic light scattering (DLS) analysis. Further, zinc oxide nanoparticles were evaluated for antiradical scavenging activity by capacity of total antioxidant assay. Synthesised ZnO nanoparticles were confirmed by the absorption maxima at the wavelength of 370 nm. TEM image revealed that ZnO nanoparticles were spherical with average size 41 nm. FTIR investigation suggested that the flavonoids, glycosides, proteins and phenols molecules can play an important role in the stabilisation of ZnO nanoparticles.

Abstract
STUDY QUESTION Is polycystic ovary morphology (PCOM) associated with metabolic syndrome (MS), insulin resistance (IR) and dyslipidemia? SUMMARY ANSWER No associations between PCOM and metabolic disorders were found. WHAT IS KNOWN ALREADY Polycystic ovary morphology has a prevalence of 21-63% in healthy women of reproductive age. Results of studies focusing on metabolic abnormalities among females with PCOM, are insufficient and controversial. STUDY DESIGN, SIZE, DURATION This was a cross-sectional population-based study from five provinces in Iran. A standard questionnaire was filled out during face-to-face interviews and clinical examinations were done. All study subjects were invited to undergo blood sampling and ultrasonographic assessment. PARTICIPANTS/MATERIALS, SETTING, METHODS From a total of 1772 women, 809 participants met the inclusion criteria of this study, i.e. non-pregnant, reproductive-age, ovulatory, normo-androgenic, without hyperprolactinemia/thyroid dysfunction. Participants were divided into two groups; 126 women with PCOM on ultrasound assessment, as the case and 683 women with normal ovarian morphology, as the control groups. The association of PCOM with MS, IR and dyslipidemia were analyzed using logistic regression models, adjusted for confounding variables. MAIN RESULTS AND THE ROLE OF CHANCE Mean systolic blood pressure (SBP), high density lipoprotein (HDL) and androstenedione (A4) serum levels of women with PCOM were significantly higher than in the normal group (P = 0.04, 0.05 and 0.008, respectively). Comparison between groups revealed dyslipidemia to be higher among controls. However the results of logistic regression models, after adjustment for possible confounding variables showed that there were no significant association between prevalence of MS, IR and dyslipidemia with PCOM. LIMITATIONS, REASONS FOR CAUTION Due to the study being cross-sectional, blood samples were collected only once thus we did not measure serum concentrations of progesterone in the luteal phase, which determines subclinical anovulation. Moreover, due to budget limitations, enzyme immunoassay was used for androgenic measurements while mass spectrometry-based assays have been known as the gold standard method. However we defined our groups very strictly to overcome these limitations. WIDER IMPLICATIONS OF THE FINDINGS It seems that biochemical and metabolic characteristics of women with PCOM do not differ significantly to those of normal women. To clarify the association between PCOM and metabolic characteristics, longitudinal studies investigating long-term metabolic disorders among women with PCOM are highly recommended. STUDY FUNDING/COMPETING INTEREST No external funding was used for this study. No conflicts of interest are declared.

Abstract
PURPOSE There is much controversy regarding the use of oral contraceptive pills (OCPs) on cardiometabolic parameters, which is why this longitudinal population-based study was conducted to assess the impact of OCP use and its duration on cardiometabolic factors. METHODS Of 5532 reproductive-aged participants of the Tehran lipid and glucose study, 3160 women who met our inclusion criteria were subdivided according to the duration of OCPs consumption into four sub-groups: (1) Non-users; (2) <11 month users; (3) 12-35 month users, and (4) ≥36 month users, and their cardiometabolic parameters were compared. RESULTS No statistical significant differences were observed between the cardiometabolic parameters of these sub-groups, after further adjustment for confounding factors including age, parity, and education, except for mean low-density lipoprotein-cholesterol which was significantly higher in women who used OCPs for >36 months in comparison to non-OCP users. The odds ratio of hypercholesterolemia was significantly higher in women who used OCPs for >36 months in comparison to non-OCP users; being 1.5 times higher than non-users (95 % CI 1.01-2.2). CONCLUSION Results showed that if used for less than 3 years, OCPs have no cardiometabolic effects.

Abstract
β1-Adrenergic receptor (β1-AR) stimulation increases apoptosis in cardiomyocytes through activation of cAMP/protein kinase A (PKA) signaling. The myocyte enhancer factor 2 (MEF2) proteins function as important regulators of myocardial gene expression. Previously, we reported that PKA signaling directly represses MEF2 activity. We determined whether (a) MEF2 has a pro-survival function in cardiomyocytes, and (b) whether β-adrenergic/PKA signaling modulates MEF2 function in cardiomyocytes. Initially, we observed that siRNA-mediated gene silencing of MEF2 induces cardiomyocyte apoptosis as indicated by flow cytometry. β1-AR activation by isoproterenol represses MEF2 activity and promotes apoptosis in cultured neonatal cardiomyocytes. Importantly, β1-AR mediated apoptosis was abrogated in cardiomyocytes expressing a PKA-resistant form of MEF2D (S121/190A). We also observed that a β1-blocker, Atenolol, antagonizes isoproterenol-induced apoptosis while concomitantly enhancing MEF2 transcriptional activity. β-AR stimulation modulated MEF2 cellular localization in cardiomyocytes and this effect was reversed by β-blocker treatment. Furthermore, Kruppel-like factor 6, a MEF2 target gene in the heart, functions as a downstream pro-survival factor in cardiomyocytes. Collectively, these data indicate that (a) MEF2 has an important pro-survival role in cardiomyocytes, and (b) β-adrenergic signaling antagonizes the pro-survival function of MEF2 in cardiomyocytes and β-blockers promote it. These observations have important clinical implications that may contribute to novel strategies for preventing cardiomyocyte apoptosis associated with heart pathology.

Abstract
BACKGROUND Exposure to organic solvents is common among workers. OBJECTIVE To assess neurobehavioral effects of long-term exposure to organic solvents among rubber workers in Tehran, Iran. METHODS Across-sectional study was conducted on 223 employees of a rubber industry. The participants completed a data collection sheet on their occupational and medical history, and demographic characteristics including age, work experience, education level; they performed 6 psychiatric tests on the neurobehavioral core test battery (NCTB) that measure simple reaction time, short-term memory (digit span, Benton), eye-hand coordination (Purdue pegboard, pursuit aiming), and perceptual speed (digit symbol). RESULTS Workers exposed and not exposed to organic solvents had similar age and education distribution. The mean work experience of the exposed and non-exposed workers was 5.9 and 4.4 years, respectively. The exposed workers had a lower performance compared to non-exposed workers in all psychomotor tests. After controlling for the confounders by logistic regression analysis, it was found that exposure to organic solvents had a significant effect on the results of digit symbols, digit span, Benton, aiming, and simple reaction time tests. No significant effect was observed in pegboard test. CONCLUSION Occupational exposure to organic solvent can induce subtle neurobehavioral changes among workers exposed to organic solvents; therefore, periodical evaluation of the central nervous system by objective psychomotor tests is recommended among those who are chronically exposed to organic solvents.

Abstract
Characterizing the signaling network that controls MEF2 transcription factors is crucial for understanding skeletal and cardiac muscle gene expression. Glycogen synthase kinase 3β (GSK3β) regulates MEF2 activity indirectly through reciprocal regulation of p38MAPK. Cross-talk between GSK3β and p38MAPK regulates MEF2 activity in skeletal and cardiac muscle. Understanding cross-talk in the signaling network converging at MEF2 control has therapeutic implications in cardiac and skeletal muscle pathology. Glycogen synthase kinase 3β (GSK3β) is a known regulator of striated muscle gene expression suppressing both myogenesis and cardiomyocyte hypertrophy. Since myocyte enhancer factor 2 (MEF2) proteins are key transcriptional regulators in both systems, we assessed whether MEF2 is a target for GSK3β. Pharmacological inhibition of GSK3β resulted in enhanced MEF2A/D expression and transcriptional activity in skeletal myoblasts and cardiac myocytes. Even though in silico analysis revealed GSK3β consensus (S/T)XXX(S/T) sites on MEF2A, a subsequent in vitro kinase assay revealed that MEF2A is only a weak substrate. However, we did observe a posttranslational modification in MEF2A in skeletal myoblasts treated with a GSK3β inhibitor which coincided with increased p38MAPK phosphorylation, a potent MEF2A activator, indicating that GSK3β inhibition may de-repress p38MAPK. Heart specific excision of GSK3β in mice also resulted in up-regulation of p38MAPK activity. Interestingly, upon pharmacological p38MAPK inhibition (SB203580), GSK3β inhibition loses its effect on MEF2 transcriptional activity suggesting potent cross-talk between the two pathways. Thus we have documented that cross-talk between p38MAPK and GSK3β signaling converges on MEF2 activity having potential consequences for therapeutic modulation of cardiac and skeletal muscle gene expression.

Abstract
BACKGROUND AND OBJECTIVES In December 2010 four, lions and one tiger died at the Tehran zoo. Out of all samples, Burkholderia mallei (causative agent of Glanders) was isolated just from ulcer sample of the tiger which was imported to Iran from Russia. MATERIALS AND METHODS One nasal swab from a tiger and fifteen blood samples with anticoagulant belonging to one tiger and fourteen lions (four dead lions and eleven live lions) were collected and were inoculated directly onto the selective media. The isolate was identified by morphological and biochemical and API BBL tests and PCR using specific primers (Bma- IS407-flip). The standard (Razi Type Culture Collection RTCC: 2375) and tiger isolates were inoculated into 2 guinea pigs. All residue solipeds and carnivores were checked by Malleination test and Complement Fixation (CF) Test respectively. RESULTS One isolate of B. mallei was isolated from tiger's nasal swab. Both of B.mallei strains were recovered from inoculated animals. All of solipeds were negative by malleination test, however, 11 lions including 4 dead and 7 live lions out of 14 lions were positive in CF test for Glanders and all were put down by the authorities. CONCLUSION Active surveillance of Glanders is essential for solipeds, especially it's more important while being used to feed valuable carnivores like lions and tigers. Therefore, a reliable test like malleination must be carried out twice (first before transferring and one month after quarantine). Both test results should be negative for use for feeding.

Abstract
The preconception period is an ideal opportunity to optimize women's health. This study of women attending premarital clinics in the Islamic Republic of Iran aimed to evaluate the impact of a health education workshop on their health locus of control and self-efficacy in physical activity. The design was a randomized controlled trial with a questionnaire before and after the intervention. At post-intervention, there were significant increases in scores of internal health locus of control and self-efficacy in the experimental group (n = 109) compared to the control group (n = 101). It was concluded that a short-term health education may empower women to adopt healthy lifestyles.

7075 Background: AML is a disease of old age, but unfortunately due to several factors standard treatment can not be delivered to these patients. Here we tried to achieve to bet possible response to these patients. Methods: Eleven old age patients selected for this trial. Patients couldn't tolerate standard treatment of AML due to old age or comorbid disorders. Treatment consist of best supportive care plus administration of low dose ARA-C (20mg/day as SQ) for 10 days each months and arsenic trioxide 10 mg/day as 2 hour iv infusion each month. Patients followed by CBC and BMA/B when peripheral blood normalized or every other month. Results: This cohort consist of 8 men and 3 women. Median age was 75 y/o (55–80). Median WBC count Hb level and platelet count at presentation were 42,860μl, 8.3g/dl and 30,500/μl, respectively. Complete remission observed in 6 and partial remission in one patient (RR = 63.6%), but remission was short live, after 6 months one patient was in CR and one in PR. After 12 months, only one patient was in PR. Median survival was 6 months and 6 patients survive more than 6 months. Two patients are alive after 12 months. Conclusions: Although prognosis of old age AML remain poor, but with this type of treatment RR is acceptable. In this very high-risk group of very old AML, combination of ATO and ARA-C possibly could improve survival. No significant financial relationships to disclose.

Abstract
In a 2-year retrospective study, the database of the microbiology laboratory of the Imam Khomeini Hospital was reviewed to identify patients who had nosocomial bacteraemia between 1 May 1999 and 31 May 2001 and identify the pathogen responsible and its resisitance to antibiotics. Of 6492 patients in various wards, 593 (9.1%) had positive blood cultures; 85 of those (14.3%) had signs of potential skin contamination. Gram-positive cocci, including coagulase-negative staphylococci, Staphylococcus aureus, Streptococcus pneumoniae and other Gram-positive cocci, accounted for 42.3% of isolates. Gram-negative bacilli were responsible for another 42.3% of isolates; Pseudomonas aeruginosa was the predominant isolate. Patterns of drug resistance varied according to species of bacteria but were generally quite high.
