Abstract
OBJECTIVES MicroRNA expression disruptions play an important function in the expansion of gastric cancer. Previous investigation has indicated that miR-372-5p doing as an oncogene in several malignancies. CDX1 and CDX2, as target genes of miR-372-5p, play the role of tumor suppressors and oncogenes in gastric cancer cells, respectively. The current investigation explored the effects of miR-372-5p regulation on CDX2 and CDX1 in AGS cell lines and studied their molecular mechanism. METHODS hsa-miR-372-5p miRCURY LNA miRNA Inhibitors and Mimic were transfected into AGS cell line. The cell viability and cell cycle calculation were defined by MTT assay and flow cytometry, respectively. The Expression levels of miR-372-5p, CDX1, CDX2 and transfection efficiency were measured using Real-time PCR. Statistical investigation p values <0.05 were considered to be meaningful. RESULTS miR-372-5p particularly was upregulated in control cells and also after transfection by mimic. While its expression was reduced by the inhibitor. Upregulation of miR-372-5p remarkably increased cell growth and led to accumulation in the G2/M phase, although the inhibitor decreased cell growth and accumulation in the S phase. Accordingly, upregulation of miR-372-5p increased CDX2 and decreased CDX1 expression. By inhibition of miR-372-5p, expression of CDX2 was decreased and expression of CDX1 was increased. CONCLUSIONS Up and down-regulation of miR-372-5P has a potential effect on the expression levels of its target genes, CDX1 and CDX22. Accordingly, the downregulation of miR-372-5p may be assumed as a possible therapeutic target in treating gastric cancer.

Abstract
Epigenetic modifications, particularly DNA methylation, is commonplace and a remarkable factor in carcinogenesis transformation. Conspicuously, previous findings have presented a cluster of irregular promoter methylation alterations related with silencing of tumor suppressor genes, little is accepted regarding their sequential DNA methylation (hypo and hyper) modifications during the cancer progression. In this way, fluctuations of DNA methylation of many genes, especially MYC, SMAD2/3, and DNMT3A, have an impressive central key role in many different cancers, including colorectal cancer (CRC). CRC is distinguished by DNA methylation, which is related to tumorigenesis and also genomic instability. Importantly, molecular heterogeneity between multiple adenomas in different patients with CRC may show diverse developmental phenotypes for these kinds of tumors. Conclusively, studying factors that are involved in CRC carcinogenesis, especially the alterations in epigenetic elements, such as DNA methylation besides RNA remodeling, and histone modification, acetylation and phosphorylation, can be influential to find new therapeutic and diagnostic biomarkers in this type of malignancy. In this account, we discuss and address the potential significant methylated modifications of these genes and their importance during the development of CRC carcinogenesis.

Abstract
Introduction Various types of cancers threaten human life. The role of bacteria in causing cancer is controversial, but it has been determined that the Helicobacter pylori infection is one of the identified risk factors for gastric cancer. Helicobacter pylori infection is highly prevalent, and about half of the world,s population is infected with it. Objective The aim of this study was the role of Helicobacter pylori in the development of gastric cancer. Method We obtained information from previously published articles. Results and Conclusion The bacterium has various virulence factors, including cytotoxin- associated gene A, vacuolating cytotoxin A, and the different outer membrane proteins that cause cancer by different mechanisms. These virulence factors activate cell signaling pathways such as PI3-kinase/Akt, JAK/STAT and Ras, Raf, and ERK signaling that control cell proliferation. Uncontrolled proliferation can lead to cancer.

Abstract
INTRODUCTION Gastric cancer is one of the most serious and lethal kinds of cancer in the world. It is a multi-step, multi-factor, and elaborated process that is associated to gene abnormal expression. This study intended to investigate the WNT16 gene's expression in human gastric tumor and the margin tissues of the stomach (normal tissues). METHODS Correspondingly, 40 samples (20 tumoral tissues and 20 non tumoral or margins tissues) were investigated in Imam Khomeini Hospital in Sari City, Mazandaran Province, Iran. In this way, real-time PCR, Taqman assay was employed to evaluate the upregulation and downregulation of this gene in both tissues in triplicate form. The GAPDH gene was selected as housekeeping gene. RESULTS Conspicuously, the results have shown a remarkable modification in tumoral tissues, and the gene expression increased significantly in tumoral tissue. CONCLUSIONS Conclusively, the upregulation of WNTt16 gene expression in tumoral tissues was impressive and the P value was 0.005 and the SE range was 0.064-142.154.

Abstract
Mounting evidences support that vitamin D insufficiency or deficiency is a risk factor of breast cancer. Vitamin D receptor (VDR) is expressed in more than 36 cell types in different organs as in cancerous cells. Numerous allelic variants of VDR gene have been identified in human populations. Association of FokI (rs2228570) and BsmI (rs1544410) single nucleotide polymorphisms (SNPs) in VDR gene with the risk of breast cancer have been investigated in several studies, however, the published data are still inconsistent. Here, we investigated BsmI and FokI polymorphisms in Iranian young (≤ 35 years old) breast cancer patient with known BRCA1/2 germline mutations. VDR gene polymorphisms were detected by restriction fragment length polymorphism (RFLP) analysis in a cohort of 203 breast cancer patients and 214 controls from Iran. There was a significant association between the bb and Bb genotypes of the BsmI and the increased risk of breast cancer (OR 1.74, CI 1.06-2.87 and OR 2.08, CI 1.31-3.29, respectively). This association was maintained in the subgroup of BRCA1/2 mutation non carriers (OR 1.90, CI 1.15-3.20 and OR 1.75, CI 1.07-2.87 for bb and Bb genotypes respectively) and in the subgroup of BRCA1/2 mutation non-carriers with a family history of breast and/or ovarian cancer (OR 1.81, CI 1.08-3.05 and OR 1.65, CI 1.00-2.70 for bb and Bb genotypes respectively). None of the FokI homozygous or heterozygous genotypes were associated with the risk of breast cancer. In summary, the BsmI polymorphism of VDR gene may be associated with the risk of breast cancer in Iranian women.

Abstract
Although most traditional Muslim scholars condemn same-sex desires and acts, revisionist Muslim scholars have offered a more tolerant approach on this issue over the last two decades. Building on an essentialist approach to same-sex desires and acts, these scholars have argued that Islam accepts difference and diversity, including sexual diversity, as part of God's creation. Homosexuality, which in their view is an innate disposition to the same sex, is an alternative sexuality and, thus, accepted by the Qur'an and Islam. This article argues that an essentialist approach is not suitable to defend all manifestations of same-sex desires and acts, not only because it is narrow (as it excludes both bisexual Muslims and homosexual Muslims who believe that their sexual orientation is socially constructed), but also because it cannot even argue the case for the view of homosexuality as inborn. This article proposes to open up the debate beyond essentialism and constructivism, which both have their limitations, to accommodate a more inclusive and tolerant Islamic approach to same-sex desires and acts.

Abstract
Memory impairment is a common disorder in diabetes mellitus which is associated with hippocampal neuronal apoptosis. The present study was conducted to examine the effect of one-week intraperitoneal (ip), administration of aminoguanidine (AG) on passive avoidance learning (PAL) and Bcl-2 family gene expression in the hippocampus of rats. Sixty male rats were divided into ten groups: non-diabetic/diabetic animals with/without AG (50, 100, 200 and 400 mg/kg, ip) treatment for one week. PAL and Bcl-2 family genes were examined. AG (100 and 200 mg/kg) improved both memory and Bax, Bak, Bcl-2 and Bcl-xl deficiency significantly in diabetic rats. AG treatment also ameliorated the diabetes-induced changes in (Bcl-2+Bcl-xl)/(Bak+Bax) ratios considerably. These results propose that one-week ip administration of AG may recover the deficit cognition in diabetic rats via enhancing (Bcl-2+Bcl-xl)/(Bak+Bax) proportions (Tab. 2, Fig. 4, Ref. 55).

Abstract
Introduction Menopause increases the risk of cardiovascular disease in women. The aims of the present study were to evaluate the effects of swimming training on cardiac histology and expression of miR-29 and IGF-1 in the ovariectomized rats. Materials and methods Thirty female Wistar rats were divided into sham and ovariectomized groups: sedentary control (OVX) and trained with 8 weeks exercise (OVX.E). On 57th day, blood was collected and used for lipid profile measurement. In addition, heart tissue was analyzed by reverse transcription-polymerase chain reaction for IGF-1 mRNA and miR-29, and studied for histopathological changes. Results Ovariectomy significantly decreased miR-29 and IGF-1 expression in the heart compared to sham animals group (p<0.05). Exercise training increased miR-29 and IGF-1 expression in the trained rats and improved histology and lipid profile compared with OVX group (p<0.05). Conclusion Estrogen deficiency could lead to cardiac fibrosis through deregulation miR-29 and IGF-1 expression. The findings of the current study suggests a protective effect of exercise on heart against fibrotic changes in ovariectomized rats and support a potential preventive value of exercise in improving cardiac function after menopause.

Abstract
CONTEXT Achillea wilhelmsii C. Koch (Asteraceae) is widely used in Iranian traditional medicine. OBJECTIVE This in vivo study evaluates the hepatoprotective role of Iranian A. wilhelmsii oils against acetaminophen-induced oxidative damages in rats. MATERIALS AND METHODS The animals were divided into five groups: in negative control and control groups, the DMSO and 500 mg/kg acetaminophen were i.p. injected, respectively. In treatment groups, 100 and 200 mg/kg oils and 10 mg/kg BHT were given i.p. immediately after acetaminophen administration. Then, the hepatic oxidative/antioxidant parameters such as lipid peroxidation (LP), glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), and ferric reducing ability of plasma (FRAP) were measured in time intervals (2, 4, 8, 16, and 24 h) after administrations confirmed by histophatological consideration at 24 h. RESULTS The results indicated that acetaminophen caused a significant elevation in SOD activity (8-24 h) and LP and FRAP levels (4 h) paralleled with significant decline in GSH level (4 and 8 h). The apparent oxidative injury was associated with evident hepatic necrosis confirmed in histological examination. The presences of A. wilhelmsii oils (100 and 200 mg/kg) with acetaminophen mitigated significantly the rise in SOD, LP, and FRAP levels and restored the GSH compared with the group treated with acetaminophen. These were confirmed by histological examination indicating the hepatic necrosis reversal by the oils. DISCUSSION AND CONCLUSION It can be concluded that concomitant administration of A. wilhelmsii oils with acetaminophen may be useful in reversing the drug hepatotoxicity.

Abstract
Abstract
Diet can play a vital role in cancer prevention. Studies have shown that a diet high in fruits and vegetables is associated with a reduced risk of cancer. Apigenin is a non-toxic and non-mutagenic natural flavonoid. Our previous studies demonstrated the effects of apigenin on angiogenesis in CAM model is by two distintic parallel PI3K/AKT and jak/STAT pathways. Vascular endothelial growth factor (VEGF) is one of the most important of all known inducers of angiogenesis and in many cancers this protein is over-expressed. Studies confirm Apigenin efficient on reduction VEGF expression. In this study, as first time, effect of Apigenin is evaluated by oral administration on angiogenesis decreasing and VEGF expression levels were measured in creatures. After infection of mice's ovarian by A2780 cancer cell line, Apigenin (75/mg/kg/day) were fed once a day for 30 days to the animals and angiogenesis measured in vivo. Histological methods were used for counting blood vessels, ELISA analysis was used to measurement of VEGF protein in infected tissues. to confirm the effect of oral administration of Apigenin on VEGF expression, A2780 cells were infected by VEGF promoter reporter vectors then injected to the mice. Studies have shown that taking these orally, Apigenin reduced VEGF expression and ultimately leads to reduced angiogenesis.

Abstract
The objectives of this study were to investigate the occurrence of Vibrio parahaemolyticus in the seawater and its sediment by molecular techniques and conventional microbiological methods. Of 300 samples analyzed, 20.3 % was recorded positive for V. parahaemolyticus. Of the 62 strains isolated, 26 (8.3 %) were obtained from the seawater samples, and 36 (12 %); from sediments. Only three strains (4.83 %) showed hemolytic activity in Wagatsuma agar. The results of this study demonstrated the presence of V. parahaemolyticus in the southern coast of the Caspian Sea (Northern Iran). Furthermore, the PCR approach proved useful for reliable confirmation of species identification. V. parahaemolyticus is an important human pathogen responsible for food-borne gastroenteritis worldwide. These findings indicated the potential sanitary risk associated with the presence of pathogenic V. parahaemolyticus in the Caspian Sea.

Abstract
The gene coding for ferric enterobactin binding protein from E. coli O157:H7 was amplifi ed. This gene was cloned and expressed as C-terminal His (6)-tagged protein. The SDS-PAGE analysis of the total protein revealed only two distinct bands, with molecular masses of 31kDa and 34kDa. The Ni-NTA chromatography purifi ed FepB and the osmotically shocked periplasmic fraction of IPTG induced cells showed only a single band of 31 kDa. Polyclonal mouse antibody was raised against the recombinant protein during 4 weeks after immunization. Western blot analysis of the recombinant FepB with mouse antiserum revealeda single band of 31 kDa. Identification and purification of FepB helped reveal its appropriate molecular mass. Polyclonal antibody raised against the recombinant protein reacted with bacterial FepB. The recombinant protein FepB could have a protective effect against E. coli O157:H7 and might be useful as an effective vaccine.

Abstract
OBJECTIVES The aim of this study was to enhance the antimicrobial efficacy of a liposomal gentamicin formulation with gallium metal (Lipo-Ga-GEN) against clinical isolates of Pseudomonas aeruginosa. METHODS Sputum isolates of P. aeruginosa from cystic fibrosis patients were used to determine the MIC and MBC of Lipo-Ga-GEN. P. aeruginosa biofilms were formed and used to compare the minimum biofilm eradication concentration of the conventional drugs with that of Lipo-Ga-GEN. Quorum sensing (QS) molecule reduction of P. aeruginosa was determined by monitoring N-acyl homoserine lactone production using Agrobacterium tumefaciens reporter strain (A136). Viability of the cultured human lung epithelial cells (A549) was determined by Trypan Blue assay in order to assess Ga toxicity. RESULTS MIC and MBC values indicated that gentamicin was more effective against a highly resistant strain of P. aeruginosa (PA-48913) when delivered as a Lipo-Ga-GEN formulation (256 mg/L free gentamicin versus 2 mg/L Lipo-Ga-GEN). Lipo-Ga-GEN was the only formulation that completely eradicated biofilms and blocked QS molecules at a very low concentration (0.94 mg/L gentamicin). The decrease in cell viability was less in A549 cells exposed to Lipo-Ga, suggesting that encapsulated Ga is safer. CONCLUSIONS The results clearly indicate that the Lipo-Ga-GEN formulation is more effective than gentamicin alone in eradicating antibiotic-resistant P. aeruginosa isolates growing in a planktonic or biofilm community.

Abstract
Chronically administered insulin returns enhanced maximal glucose transport capacity induced by diabetes to its normal state. In this study, the direct and acute effects of insulin on glucose transport in different parts of isolated small intestine were investigated. Mucosal Fluid Transport (MFT), Mucosal Glucose Transport (MGT) and Serosal Glucose Transport (SGT) were measured in the presence and absence of insulin in averted sacs, prepared from female Wistar rats. This study shows that the presence of insulin in vitro (40 and 80 microU/mL) can reduce MGT and SGT in different segments of the small intestine (duodenum, jejunum and ileum) after 30 min whereas it had no effect on MFT. Mucosal glucose transfer rates in the duodenum, jejunum and ileum of the controls were 6.07+/-0.4, 6.34+/-0.62 and 6.43+/-0.47 mg/g tissue respectively which were significantly reduced to 3.82+/-0.93, 3.60+/-0.50 and 1.17+/-0.45 in the presence of 80 microU/mL of insulin. Serosal glucose transfer too was decreased significantly from 0.3+/-0.05, 0.57+/-0.07 and 0.43+/-.07 in the duodenum, jejunum and ileum to 0.16+/-0.03, 0.16+/-0.04 and .07+/-.02 respectively. Mucosal fluid transfer was not affected by insulin. Insulin was as effective whether it was added on the mucosal or the serosal side. The results of this study show that insulin can directly affect glucose transport in the small intestine; its physiological role must be examined. Direct effect of insulin deficiency on glucose absorption in diabetic patients may play a role in the pathophysiology of the disease.

Abstract
The anterograde projections of the motorcortical tongue area to the hypoglossal nucleus and neighbouring structures were studied in the rhesus monkey, squirrel monkey, saddle-back tamarin and tree shrew. Biotin dextranamine served as tracer. Direct projections into the hypoglossal nucleus were only found in the rhesus monkey and squirrel monkey. All four species, however, showed a direct projection into the dorsal and parvocellular reticular formation which in turn projects into the hypoglossal nucleus. The findings suggest a phylogenetic trend in the projections of the motorcortical tongue area from non-primate mammals via non-human primates to man in the sense that the cortico-motoneuronal connection is strengthened towards man. This might be one reason for the superior role the tongue plays in human vocal behaviour in contrast to non-human vocalization.

Abstract
In altogether seven tree shrews, Tupaia belangeri, the anterograde projections of the motorcortical tongue area were investigated as part of a larger comparative study. Identification of the tongue area was carried out by electrical brain stimulation. Three different tracers were used: biotin-conjugated dextranamine (BDA), Phaseolus vulgaris leucoagglutinin (PHA-L) and 3H-leucine. Intracortical projections were found to the motor cortex around the injection site, the premotor cortex, supplementary motor area, the homologues of the primate frontoparietal operculum and insula, the anterior cingulate and agrannular retrosplenial cortex, the somatosensory and bordering inferior parietal cortex as well as to the perirhinal cortex. Except the very weak projections into the retrosplenial, posterior parietal and perirhinal region which were ipsilateral, all other projections were bilateral. Subcortically, there was a projection into the ventral putamen, rostrodorsal claustrum and, very sparsely, into the caudate nucleus. In the thalamus, terminal labeling was found in the nuclei reticularis, anteroventralis, anteromedialis, ventralis lateralis, ventralis posterior medialis, ventralis posterior inferior, medialis dorsalis, in the intralaminar nuclei paracentralis, centralis lateralis, centrum medianum and parafascicularis, in the midline thalamus and in the nuclei posterior and pulvinaris. Further diencephalic projections, however all of them wak, could be traced into the zona incerta, dorsolateral subthalamus, dorsomedial, lateral and supraoptic hypothalamus. In the midbrain, labeling was found in the deep layers of the lateral superior colliculus, in the bordering reticular formation and, very sparsely, in the periaqueductal grey. In the lower brain-stem, fibres ended in the griseum pontis, dorsolateral reticular formation, principal and spinal trigeminal nucleus and, sparsely, in the lateral parabrachial region, solitary tract nucleus, inferior olive and magnocellular reticular formation. No terminals were found in the hypoglossal nucleus. The projection system revealed with PHA-L was less extensive than that demonstrated with BDA and 3H-leucine, both of which were similar.

Abstract
OBJECTIVES Increasing interest in environmental health issues has created a demand for improved methods for the assessment of pollutant effects on humans. Our laboratory has developed an in vitro assay for the quantification of genotoxicity, monitored as DNA single strand breaks (SSB), in the HepG2 human hepatoma cell line. DESIGN AND METHODS This assay procedure, which is based upon alkaline unwinding and hydroxylapatite DNA chromatography, is both rapid and simple to perform. RESULTS HepG2 cells responded to the standard mutagen, 4-nitroquinoline N-oxide, demonstrating SSB formation at concentrations above 0.1 mumol/L. Phenanthrene-9,10-quinone, a component of diesel exhaust, mediated SSB formation at concentrations above 250 nmol/L. Finally, an extract of contaminated sediment from the Great Lakes Basin mediated SSB formation in a dose-dependent manner. CONCLUSIONS These results illustrate the utility of this human genotoxicity assay for future use in screening of environmental pollutants.
