Abstract
BACKGROUND Non-muscle-invasive bladder cancer (NMIBC) has a high recurrence rate and muscle-invasive bladder cancer (MIBC) has unfavorable outcomes in urothelial bladder cancer (UBC) patients. Complex UBC-related protein biomarkers for outcome prediction may provide a more efficient management approach with an improved clinical outcome. The aim of this study is to recognize tumor-associated proteins, which are differentially expressed in different stages of UBC patients compared non-cancerous tissues. METHODS The proteome of tissue samples of 42 UBC patients (NMIBC n = 25 and MIBC n = 17) was subjected to two-dimensional electrophoresis (2-DE) combined with Liquid chromatography-mass spectrometry (LC-MS) system to identify differentially expressed proteins. The intensity of protein spots was quantified and compared with Prodigy SameSpots software. Functional, pathway, and interaction analyses of identified proteins were performed using geneontology (GO), PANTHER, Reactome, Gene MANIA, and STRING databases. RESULTS Twelve proteins identified by LC-MS showed differential expression (over 1.5-fold, p < 0.05) by LC-MS, including 9 up-regulated in NMIBC and 3 up-regulated in MIBC patients. Proteins involved in the detoxification of reactive oxygen species and cellular responses to oxidative stress showed the most significant changes in UBC patients. Additionally, the most potential functions related to these detected proteins were associated with peroxidase, oxidoreductase, and antioxidant activity. CONCLUSION We identified several alterations in protein expression involved in canonical pathways which were correlated with the clinical outcomes suggested might be useful as promising biomarkers for early detection, monitoring, and prognosis of UBC.

Abstract
Urothelial bladder cancer (UBC) is a heterogeneous multifactorial malignancy with a high recurrence rate. Current procedures for UBC diagnosis suffering from the lack of clinical sensitivity and specificity screening tests. Therefore, biomarkers have promising values to predict pathological conditions and can be considered as effective targets for early diagnosis, prognosis and antitumor immunotherapy. Recently, researchers have been interested for tumor proteins as biomarkers for different diseases. At present, proteomics methods have rapidly progressive that has potential identified biomarkers of UBC. Specifically, there has been several studies on the potential application of proteomics for the identification, quantification, and profiling of proteins for UBC in different sources. Based on these studies, using the panel of biomarkers as proteomic patterns may achieve higher sensitivity and specificity than single proteins in the diagnosis of UBC. In the present review, we evaluate recent literature related to the UBC proteome focusing especially on new proteomics techniques. Moreover, we classify UBC tumor biomarkers as diagnostic, prognostic, and therapeutic targets based on their sources (urine, serum/plasm, cell line, and tumor tissue) and we also discuss the advantages and limitations of each source. In this manner, this review article provides a critical assessment presentation of the advances in proteomics for all aspects of UBC diagnosis, prognosis, and treatment based on sources.

Abstract
A systematic review and meta-analysis were conducted to find out if there was association between Plasminogen Activator Inhibitor-1 (PAI-1) gene polymorphisms (- 844 G > A and - 675 4G > 5G) and susceptibility to coronary artery disease (CAD). Search of electronic databases was performed and the pooled odds ratio (OR) and 95% confidence interval (CI) were exerted to evaluate the pooled association between the single-nucleotide polymorphisms (SNPs) and risk of CAD. For - 675 4G > 5G SNP, dominant (OR = 0.90), recessive (OR = 0.90), allelic (OR = 0.91), homozygous (OR = 0.84), and heterozygous (OR = 0.96) models were significantly associated with decreased risk of CAD. Moreover, all five genetic models were associated significantly with decreased CAD risk in the Causation and Arab populations. The results in Asians were marginally significant in recessive, allelic, and homozygote models. The male gender was found to be a risk factor in individuals with PAI-1 4G > 5G SNP in the dominant model (OR = 0.89), recessive model (OR = 0.91), allelic model (OR = 0.92), homozygous model (OR = 0.86), and heterozygous model (OR = 0.91). The results of pooled ORs for overall populations and subgroup analysis by ethnicity reject any association between PAI-1 gene - 844 G > A polymorphism and CAD risk under all genetic comparisons. The results of this meta-analysis indicated that PAI-1 4G > 5G SNP was associated with decreased risk of CAD in the overall population as well as in the Asians, Caucasians, and Arab populations. However, the PAI-1 gene - 844 G > A polymorphism had no significant association with susceptibility to CAD.

Abstract
Epstein–Barr virus (EBV) associated with several diseases such as contagious mononucleosis chronic active EBV infection, and diverse sorts of malignant tumors. Therefore, using applicable vaccines could be advantageous for public health. Yet, the vaccine has been unavailable to protect from EBV so far. In the current study, to develop a multi-peptide vaccine for EBV and assess its expression in Pichia pastoris yeast system, three immunodominant sequences in glycoprotein (gp) 85, gp350 and latent membrane protein 1 (LMP1) were chosen. To construct fusion peptide, -GGGGS- liker was applied. After cloning the fusion peptide in the pPICZαA expression vector, this recombinant vector processed and transfected into Pichia pastoris host cells. The expression of high level of EBV fusion peptide was confirmed by dot blot and SDS-PAGE procedures. The Pichia pastoris is capable of supporting EBV fusion peptide expression. The application of this fusion peptide as a peptide vaccine to fight EBV is suggested.

Abstract
Background: Coronary heart disease (CHD) is a chronic inflammatory disease, which is still regarded as a major cause of morbidity and mortality worldwide. Several studies have suggested that polymorphisms in cytokine genes are associated with the pathogenesis of CHD. The genotype distribution of Tumor necrosis factor alpha (TNF-α) and interferon gamma (IFN-γ) genes polymorphisms have been shown to be different in various ethnic populations. This study was aimed to investigate the association of TNF-α-308 G/A and IFN-γ + 874T/A polymorphisms with risk of CHD in an Iranian population. Methods: A total of 187 unrelated subjects comprised 96 CHD patients and 91 healthy controls were enrolled in this cross-sectional study. The TNF-α-308 G/A and IFN-γ + 874T/A polymorphisms were genotyped using amplification refractory mutation system-PCR (ARMS-PCR). The chi-square and logistic regression tests were used to calculate the odds ratios (ORs) as a measure of differences in genotype frequencies. Results: A significant differences in the allelic and genotypic distribution of TNF-α-308 G/A and IFN-γ + 874T/A polymorphisms was found between CHD patients and healthy controls (P = 0.017, P = 0.011, P = 0.006 and P = 0.002, respectively). Logistic regression analyses were also revealed statistically significant risk for CHD with respect to TNF-α-308 A and IFN-γ + 874 T carriers either in crude or after adjustment for potential confounders (P = 0.003 and P = 0.006, respectively). Conclusion: This study provides strong evidence supporting the association of TNF-α-308G/A and IFN-γ + 874T/A polymorphisms with the increased risk of CHD. Therefore, these two cytokine polymorphisms may play a role in predisposition to coronary heart disease.

Abstract
Opium is considered as the second most abused addictive compound in worldwide. It seems that one of the causes for common consumption of opium in many countries is a traditional belief, even among medical personnel, through which opium might have advantageous influences on cardiovascular events and be beneficial in controlling hypertension, dyslipidemia, and diabetes. According to several investigations, it is thought that opium not only has no beneficial effects on cardiovascular events, but it might have deleterious influences on these settings. As a result, people need to be trained with regard to the adverse effects of opium on cardiovascular events. In this review, we try to go through the understanding of the effects of opium cardiovascular disorders and related complications such as blood pressure, blood sugar, lipid circumstances, and finally atherosclerosis.

Abstract
Objective(s): Juvenile idiopathic arthritis (JIA) is one of the most common chronic rheumatic diseases in children. The complex nature of this immune-mediated disease owes itself to several predisposing genes and environmental factors affecting its pathogenesis. Conducted in Iran, this study was originally intended to investigate every possible association between HLA DRB1 alleles and a susceptibility to JIA. Materials and Methods: In this case-control study, 45 patients with a definite diagnosis of JIA based on International League against Rheumatism (ILAR) criteria were compared against 46 healthy controls. DNA samples taken from both groups were analyzed using PCR-sequence specific primers (PCR-SSP) method. Data analysis including parametric and nonparametric test and multivariate analysis was undertaken using the SPSS 11.5 software. A P-value< 0.05 was regarded as statistically significant. Results: Mean ages in case group and healthy controls were 14.64±6.21 and 13.73±6.39, respectively with no significant difference between the two groups (P=0.515). Sex difference between JIA group and healthy controls was also not significant (P=0.068). The frequency of HLA-DRB1*01 was found the most frequent HLA-RB1 in our patients (33.3%). No significant statistical correlation between various HLA-DRB1 alleles and clinical subtypes of the disease could be established from the data. HLA-DRB1*11 was shown to raise protection to JIA (P=0.035, OR=2.755, 95% CI=0.963-8.055) in northeastern Iran. In addition, we found that HLA-RB1*09 is nominally associated with an increased risk of JIA (P=0.56, OR=2, 05, 95% CI=0.18-23.63). Conclusion: HLA-DRB1*11 was shown to raise protection to JIA in northeastern Iran. The disparity of findings in other ethnicities prompts further investigations with larger sample sizes.

Abstract
Several studies have estimated breast cancer risk in patients with systemic lupus erythematosus (SLE) relative to the general population. However, the results have been inconclusive. Therefore, we conducted a meta-analysis to ascertain a more comprehensive conclusion. A systematic literature search of electronic databases including PubMed, Web of Science, Embase, Cochrane Library, and Scopus was conducted to identify eligible studies using multiple search strategies. Based on the degree of heterogeneity, a random-effect model was chosen to calculate the pooled standardized incidence rate (SIR) with 95% confidence interval (CI), to estimate the strength of association between SLE and breast cancer incidence risk. A total of 18 eligible studies including 110,720 patients with SLE were enrolled in this meta-analysis. The combined results showed no significant association between SLE and breast cancer incidence (SIRs = 1.012 (95% CI, 0.797-1.284)). Subgroup analysis by study type, ethnicity, follow-up years, sample size, and SLE diagnostic criteria also showed no altered risk for breast cancer incidence (the summary risk estimate of each subgroup ranged from 0.82 to 1.40 with no statistical significance). This meta-analysis suggests no direct association between SLE and risk of breast cancer incidence.
