Studies that were designed pre and post anti-TNF drug treatment, were selected. After determining the search strategy for this study, the relevant data were extracted. • RESULTS: The initial search was performed in the target databases and a total of about 1458 articles were found. Fifteen articles were selected for systematic review and only 12 of them had inclusion criteria for Meta-analysis (with visual acuity data). The mean dose of prednisolone before and after biological treatments was reported in 5 studies (28.56 and 7.56 mg/kg, respectively). Also, the preliminary results indicate a significant reduction in visual acuity logMAR levels (MD=-1.5 IU/L, 95%CI:-2.1,-0.01). • CONCLUSION: Biological drugs significantly reduce the dose of prednisolone and affect visual acuity values.

In this study, we sought to investigate the mutation spectrum of the MEFV gene and any genotype–phenotype correlations.Methods and materials400 unrelated Azari‐Turkish FMF patients were analyzed in this study. Mutations in exons 2, 3, 5, and 10 of the MEFV gene were investigated using direct Sanger sequencing, and their correlations with the clinical features of the patients were analyzed.ResultsAt least one mutation was detected in 248 (62%) patients. The most common mutations were M694V (26.25%) and E148Q (24.75%), respectively. Abdominal pain (65.2%) and fever 204 (51%) were the most frequent clinical problems in all subjects. The analysis recognized a novel missense mutation in the coding region of the MEFV gene, named P313H, which is the first report of a new mutation in exon 2 of the MEFV gene in an Azari‐Turkish family.ConclusionGenotype–phenotype correlations obtained from this study would be helpful in the diagnosis and management of FMF patients in clinical situations. This novel missense mutation may provide useful evidence for further studies of FMF pathogenesis.

There are a few techniques available in the literature for the problem of goodnessof-fit for interval censored data. In this paper, we propose a new goodness-of-fit testing procedure for interval censored data and employ this for the failure time of the first permanent molar tooth (sixth tooth) data. Materials and Methods: Two methods of goodness-of-fit for interval censored data that are based on randomly generated data from each interval and averaging over the test statistics or over the p-values are employed for the failure time of the first permanent molar tooth data. Results: The mean of the failure time of the first permanent molar tooth is found to be at 95 months. The p-values of the two goodness-of-fit testing procedures for the Weibull, log-normal and gamma models are calculated. Conclusion: By comparing the p-values, the log-normal model is considered as the best model to describe the failure time of the first permanent molar tooth data.

Despite the increase in cases of this cancer, the current therapeutic strategy is not effective. This study aimed to investigate the effect of cisplatin (Cis) with alantolactone (ALT) and ZnO nanoparticles (ZnONPs) in inducing apoptosis in SKOV3 ovarian cancer cells line. Experimental approach: To evaluate the viability of SKOV3 cells and determine the IC50 of Cis, ALT, and ZnONPs, MTT assay was used. Real-time PCR and western blotting were used to evaluate the expression levels of genes (XIAP, cyclin D1, Bcl-2, Bax, and MDM2) and proteins (XIAP, cyclin D1, Bcl-2, Bax), respectively. Also, cellular ROS levels were assessed by fluorimetry. Findings / Results: Our results showed that ALT and ZnONPs significantly increased the response to Cis in SKOV3 cells compared to the control and this response is remarkably increased in the triple combination (ALT-Cis-ZnONPs). The expression of XIAP, cyclin D1, and Bcl-2 genes and proteins in the groups treated with ALT, Cis, and ZnONPs as a single agent, double and triple combination were significantly reduced compared to the control, while Bax was generally shown an increase. Also, the level of intracellular ROS is higher in the treatment groups than in the control group and the highest increase was observed in the triple combination. Conclusion and implications: Taken together, our data demonstrated the potential therapeutic approach of using ALT and ZnONPs that may enhance the apoptotic effects of Cis on the SKOV3 cells.

Epigenetic modifications of the foxp3 gene at its regulatory regions control the chromatin accessibility for the transcription factors and other transcriptional regulators in order to control Foxp3 expression. In addition, the methylation status of CpG islands within the Foxp3 promoter and regulatory elements regulate the expression of Foxp3. This study was performed to assess the role of the foxp3 gene in patients with Behçet’s syndrome (BS). Venous blood samples were collected from all participants and peripheral blood mononuclear cells (PBMC) were extracted through Ficoll-Hypaque method. Genomic DNA was randomly sheared by sonication and immunoprecipitated with a monoclonal antibody. The status methylation of the foxp3 gene was estimated in 108 blood samples of active BS patients and healthy individuals (controls); using methylation D...

These genes, through the JAK/STAT signalling pathway, affect different cytokines on cell function and subsequently lead to the pathophysiology of diseases, especially autoimmune diseases. In addition, altering the methylation of genes can affect their expression. Since the aetiology and pathology of Behcet's disease is not fully understood, the aim of this study was to determine the methylation pattern of BCL2 and BAX genes in patients with Behcet's disease and compare it with those of control group. This was a case–control study on 51 patients with Behcet and 61 control subjects. Blood samples were received from all subjects. Subsequently, the peripheral blood mononuclear cells (PBMCs) were isolated by Ficoll method and the methylation of the sites was investigated using quantitative methylation specific PCR (qMS‐PCR) technique after extraction of DNA by salting out method and its examination with Nano drop. The results of methylation and expression of Bax gene suggest that the methylation level in the patient group significantly increased compared to the healthy individuals (p‐value < .05). Furthermore, the results related to Bax gene expression revealed that the mean of gene expression in the patient group has decreased compared to the healthy group, and this decrease was statistically significant (p‐value < .05). The rate of expression and methylation of Bcl2 did not indicate any change in the two patient and healthy groups. Given the results of this study, it can be guessed that perhaps DNA methylation is involved in certain conditions of the disease and it may result in regulation of the expression of the involved genes such as Bax gene, in the pathogenesis of the disease.

Hospitalization of this patient may impose additional costs and waste the time, early discharge may lead to miss the patients. The aim of this study was to determine volubility of Single Photon Emission Computed Tomography (SPECT) in management of patients admitted to emergency department with atypical manifestations of angina pain, un-diagnostic Electrocardiogram (ECG) and negative enzyme. Half of 100 patients admitted to emergency department with atypical chest pain and un-diagnostic ECG who were candidate for admission, underwent ECG gated resting SPECT. According to the results of SPECT, low risk patient discharged after negative stress SPECT. All discharged patients were followed up for major cardiac events (cardiac death, nonfatal myocardial infarction and repeat admission for congestive heart failure) for 12 months. According to rest SPECT Myocardial Perfusion Imaging (MPI), about 70% of patients in case group was low risk and 30% of them had moderate or high risk. Case group represented lower hospitalization rate and lower need for Coronary Artery Angiography (CAG) in comparison with control group. Mean cost in case group was significantly lower than control group (175.15$ vs. 391.33$, P < 0.001). In one year follow- up no cases of mortality or major cardiovascular events as cardiac infraction were found in discharged patients in case group. our study showed that rest SPECT fulfillment in admitted patients in emergency department was validated method for assessing patients’ risk which avoids unnecessary hospitalizations and additional costs.

Each retrograde material was mixed and carried into 30 sterile custom-made plastic cylinders. Half of the samples in each group were exposed to Osteon II. All cylinders were submerged in simulated tissue fluid and incubated at 37C and 100% relative humidity for 7 days. Surface microhardness values of each study group was attained using Vicker's microhardness test. The data were analyzed statistically using two-way ANOVA and independent test at a significance level of 0.05. In all the setting conditions, BD had significantly greater surface microhardness than MTA (<0.001). Surface microhardness of both materials was significantly reduced in the presence of osteon II (=0.006 for BD and <0.001 for MTA). Mineralized bone graft materials negatively affect surface microhardness of bo...

It is significantly down-regulated in many autoimmune diseases such as Behçet's disease; this is mostly associated with more aggressive complications. Nevertheless, the essential molecular process for its low expression has not been completely realized. The aim of this project was attempted to estimate the gene expression, promoter methylation, and protein levels to IL-10's down-regulated expression. In this study, blood samples from 51 (4 missed) patients and 63 (2 missed) healthy controls were taken, with the mononuclear cells isolated by the Ficoll Protocol. DNA and RNA were then subsequently extracted. Promoter methylation levels were evaluated by MeDIP-qPCR. Following this, the extracted RNA was converted to cDNA using the RT-PCR method, wi...

Nevertheless, the essential molecular process for its high expression has not been completely realized. The aim of this study was undertaken to estimate the gene copy number variation and promoter methylation to IL-6's high expression. This study was performed on 51 patients and 61 healthy controls. Initially, DNA and RNA were extracted from all specimens. Promoter methylation levels of IL-6 were evaluated by MeDIP-qPCR technique. Also, IL-6 gene expression was measured by Real-time PCR. After that, we evaluated the relationship between gene expression and methylation, as well as their relationship with clinical specification. As we expected, the expression level of IL-6 gene increased significantly in the patient group compared to the healthy subjects. Also, the relative promoter methylation level of the IL-6 mRNA was signif...

Although several chemotherapeutics have been developed to treat this type of cancer, issues remain such as low survival rates and high reoccurrence after chemotherapy and radiotherapy. To explore a chemopreventive approach to enhancing breast cancer treatment efficacy, the antiproliferative effects of a combination of chrysin and silibinin, two herbal substances, in T47D breast cancer cells were assessed. Materials and Methods: Cytotoxicity of the agents singly and in combination was evaluated by MTT assay. Also, qRT-PCR was used to measure the expression levels of hTERT and cyclin D1 genes after 48 h treatment. Results: Cell viability assays revealed that chrysin or silibinin alone inhibited proliferation in a dose and time-dependent manner, and combining the drugs synergistically induced growth inhibition in the breast cancer cell line. The precise nature of this interaction was furthe...

Surface microhardness values of each study group was attained using Vicker's microhardness test. The data were analyzed statistically using two-way ANOVA and independent test at a significance level of 0.05. In all the setting conditions, BD had significantly greater surface microhardness than MTA (<0.001). Surface microhardness of both materials was significantly reduced in the presence of osteon II (=0.006 for BD and <0.001 for MTA). Mineralized bone graft materials negatively affect surface microhardness of bo...

It is significantly down-regulated in many autoimmune diseases such as Behçet's disease; this is mostly associated with more aggressive complications. Nevertheless, the essential molecular process for its low expression has not been completely realized. The aim of this project was attempted to estimate the gene expression, promoter methylation, and protein levels to IL-10's down-regulated expression. In this study, blood samples from 51 (4 missed) patients and 63 (2 missed) healthy controls were taken, with the mononuclear cells isolated by the Ficoll Protocol. DNA and RNA were then subsequently extracted. Promoter methylation levels were evaluated by MeDIP-qPCR. Following this, the extracted RNA was converted to cDNA using the RT-PCR method, wi...

Nevertheless, the essential molecular process for its high expression has not been completely realized. The aim of this study was undertaken to estimate the gene copy number variation and promoter methylation to IL-6's high expression. This study was performed on 51 patients and 61 healthy controls. Initially, DNA and RNA were extracted from all specimens. Promoter methylation levels of IL-6 were evaluated by MeDIP-qPCR technique. Also, IL-6 gene expression was measured by Real-time PCR. After that, we evaluated the relationship between gene expression and methylation, as well as their relationship with clinical specification. As we expected, the expression level of IL-6 gene increased significantly in the patient group compared to the healthy subjects. Also, the relative promoter methylation level of the IL-6 mRNA was signif...

Although several chemotherapeutics have been developed to treat this type of cancer, issues remain such as low survival rates and high reoccurrence after chemotherapy and radiotherapy. To explore a chemopreventive approach to enhancing breast cancer treatment efficacy, the antiproliferative effects of a combination of chrysin and silibinin, two herbal substances, in T47D breast cancer cells were assessed. Materials and Methods: Cytotoxicity of the agents singly and in combination was evaluated by MTT assay. Also, qRT-PCR was used to measure the expression levels of hTERT and cyclin D1 genes after 48 h treatment. Results: Cell viability assays revealed that chrysin or silibinin alone inhibited proliferation in a dose and time-dependent manner, and combining the drugs synergistically induced growth inhibition in the breast cancer cell line. The precise nature of this interaction was furthe...
