Abstract
BACKGROUND Although the importance of miRNA variants in female reproductive disorders has been frequently reported, the association between miRNA polymorphisms and recurrent pregnancy loss (RPL) has been poorly studied. In this study, we aimed to assess the correlation of four different miRNA variants to unexplained RPL. METHODS AND RESULTS The prevalence of four SNPs including miR-21 rs1292037, miR-155-5p rs767649, miR-218-2 rs11134527, and miR-605 rs2043556 in 280 cases with iRPL and 280 controls was performed. The DNA was extracted from all subjects and the SNPs were genotyped using RFLP-PCR methods. The data revealed that rs1292037 and rs767649 were significantly associated with higher rates of iRPL in patients compared with controls while rs11134527 and rs2043556 showed no association with increased rates of iRPL among patients. The haplotypes T-A-G-G and T-A-G-A were the most frequent in both cases and controls. Three haplotypes including T-T-G-A, C-T-G-G, and T-A-A-A showed significantly different frequencies in patients in comparison to healthy females. CONCLUSION This study suggests that rs1292037 and rs767649 could be risk factors for increased rates of iRPL.

Abstract
It is widely accepted that kisspeptin plays an integral role in the regulation of reproduction. Genetic variations in the KISS1 gene have been frequently reported to be linked to reproductive diseases, but there is still a lack of data on the association between KISS1 variations and female reproductive disorders. The present study aimed to examine the association of three missense SNPs in the KISS1 gene including rs12998, rs35431622, and rs4889 in association with idiopathic recurrent pregnancy loss (iRPL). A total of 720 individuals were recruited in this study. The DNA from the blood sample was extracted and genotyped using the PCR method. Haplotype and linkage disequilibrium (LD) have also been analyzed. The results of this study suggested that rs12998 G > A and rs4889 C > G had a significant association with iRPL (p < 0.05); while rs35431622 A > G didn't indicate any association with iRPL. A significant association was also found for three haplotypes including C-A-A, G-G-G, and G-G-A in this population. The analysis also showed a significant LD between rs12998 and rs35431622 (P < 0.0005). The rs12998 G > A and rs4889 C > G variants of KISS1 are linked to unexplained recurrent pregnancy loss and may be risk factors for this disease.

Abstract
We conducted a genome-wide association study in a large population of infertile men due to unexplained spermatogenic failure (SPGF). More than seven million genetic variants were analysed in 1,274 SPGF cases and 1,951 unaffected controls from two independent European cohorts. Two genomic regions were associated with the most severe histological pattern of SPGF, defined by Sertoli cell-only (SCO) phenotype, namely the MHC class II gene HLA-DRB1 (rs1136759, P = 1.32E-08, OR = 1.80) and an upstream locus of VRK1 (rs115054029, P = 4.24E-08, OR = 3.14), which encodes a protein kinase involved in the regulation of spermatogenesis. The SCO-associated rs1136759 allele (G) determines a serine in the position 13 of the HLA-DRβ1 molecule located in the antigen-binding pocket. Overall, our data support the notion of unexplained SPGF as a complex trait influenced by common variation in the genome, with the SCO phenotype likely representing an immune-mediated condition. A GWAS in a large case-control cohort of European ancestry identifies two genomic regions, the MHC class II gene HLA-DRB1 and an upstream locus of VRK1, that are associated with the most severe phenotype of spermatogenic failure.

Abstract
AIM Recurrent pregnancy loss (RPL) is a common reproductive disorder among women and a major cause of infertility among them; however, the underlying causes of RPL remain unknown which have led to great difficulties and complications in the treatment. MicroRNAs (miRNA) have been shown to be a potential diagnosis tools in different reproductive disorders. This study aimed to investigate the association of four different miRNA variants with the risk of idiopathic RPL (iRPL). METHODS A total of 450 women including 225 patients and 225 controls were recruited in this study. DNA was extracted, and genotyped by PCR method. Haplotype analysis, as well as linkage disequilibrium between SNPs, was performed. CONCLUSION This study suggested that rs4636297, rs41291957, and rs353292, but not rs531564 can play a risk factor role for iRLP.

Abstract
Introduction: Alterations in certain microRNAs (miRNAs) and their target genes have reported in polycystic ovary syndrome (PCOS) and other disease of the female reproductive system, and so may be potential biomarkers. We hypothesised alterations in the prevalence of four miRNAs single nucleotide polymorphism (SNP) variants miR-126 rs4636297, miR-146a rs2910164, miR-196a2 rs11614913, and miR-499 rs3746444 in women with PCOS in comparison to healthy controls. Methods: SNPs in the four miRNAs were determined in 385 patients and 385 controls by standard RT-PCR techniques. Results: SNPs in miR-126 and miR-246a were significant linked with PCOS under the allelic, dominant, co-dominant, and recessive models (all p ≤ 0.01). The SNP in miR-499 was linked to PCOS in allelic (T, p = 0.002), dominant (p = 0.035) and recessive (p = 0.003) models. The SNPs -196a was significant linked to PCOS only in the recessive model (p = 0.037). Combining these SNPs in miR-499, mi146a, miR-196a and miR-126 respectively into allele haplotypes found highly significant odds ratios (95% CI) of 0.40 (0.29–0.54) (p < 0.001) for the C-G-C-G haplotype, and 0.46 (0.30–0.70) (p = 0.002) for the C-C-C-A haplotype (p = 0.002) for PCOS. Conclusion: Single SNPs and haplotype combinations in certain SNPs in miR-126, miR-146a, miR-196a2 and miR-499 are strongly linked to PCOS, and so may be useful predictors of this condition.

Abstract
Background: While different studies have investigated the association of SNPs with female reproductive disorders, a limited number of studies have investigated the effect of microRNAs variants in endometriosis. In this study, we evaluated the prevalence and the association of three different miRNAs variants including, miR-27a rs895819, miR-124-1 rs531564, and miR-423 rs6505162 with endometriosis to help further elucidate the importance of these variants in female reproductive disorders. Methods: A total number of 440 women (220 cases and 220 controls) were included. DNA was extracted and genotyping of the SNPs was carried out by PCR. Results: The results showed that rs895819 and rs6505162 had a significant association with endometriosis under the dominant, recessive, co-dominant, and allelic model, but rs531564 was not linked to endometriosis. Our results also imply a protective effect on endometriosis severity for AG genotype and G allele in rs895819 (p < 0.001), and also for AA and AC genotypes in rs6505162 with severity in endometriosis (p < 0.001). Moreover, Hardy–Weinberg equilibrium, haplotype frequency, and linkage disequilibrium between SNPs were performed. Conclusion: miR-27a rs895819 and miR-423 rs6505162, but not miR-124-1 rs531564, are linked to endometriosis.

Abstract
BACKGROUND Hepatitis B virus (HBV) has been considered a significant cause of human reproductive failure in different studies; however, there is a considerable disagreement on the true impacts of HBV on female reproduction. This study has evaluated the impact of HBV infection on pregnancy complications in natural pregnancy and also on pregnancy outcomes in women undergoing in vitro fertilization (IVF) treatment. METHOD We searched Embase, Web of Science, PubMed and Google Scholar databases to identify the potentially relevant studies. Summary odds ratio (OR) or standardized mean difference (SMD) with 95% confidence interval (CI) was applied to assess the relationship. Heterogeneity testing, sensitivity analysis and publication bias testing were also performed. RESULTS A total of 42 studies concerning the effect of HBV infection on the natural and IVF pregnancy were included in this study. Our meta-analysis results revealed that HBV infection had a positive correlation to gestational diabetes mellitus (GDM) [OR = 1.32 (1.17-1.48) (p < 0.01)] and preterm birth [OR = 1.26 (1.14-1.40) (p < 0.01)] in natural pregnancy; however, HBV infection was not significantly associated with decreased fertility rates among the patients who underwent IVF. CONCLUSION This study revealed a strong association of GDM and preterm birth with higher rates of HBV infection in pregnant women. Also, our results suggested that HBV infection in patients undergoing IVF may not negatively influence the pregnancy outcome. It may be rational to conclude that IVF might be rather a safe and effective method for HBV+ females who desire to have children.

Abstract
Background: MicroRNAs (miRNAs) are naturally occurring posttranscriptional regulatory molecules that potentially play a role in endometriotic lesion development.Method: We evaluated the prevalence of miRNAs variants miR-146a rs2910164, miR-149 rs2292832, miR-196a2 rs11614913, and miR-499 rs3746444 in endometriosis in 260 cases and 260 controls. DNA was extracted and genotyping of the SNPs was carried out by PCR.Results: There was a significant association of rs2910164 and rs2292832 with increased rates of endometriosis under the dominant (p < 0.001), recessive (p < 0.05), co-dominant (p < 0.001), and allelic model (p < 0.001). Also, rs3746444 showed a borderline association with endometriosis under the recessive model (p = 0.05); however, rs11614913 was not linked to endometriosis. Further analysis indicated the significant association of miR-146a rs2910164 polymorphism genotypes (GG, GC, and CC) and miR-149 rs2292832 genotypes (CC and CT) with endometriosis severity in patients (p < 0.001). Additionally, haplotype frequency in cases compared to controls and Linkage disequilibrium (LD) between the mentioned SNPs was appraised.Conclusion: MiR-146a, miR-149 and miR-499 may have a role in the pathogenesis of endometriosis.

Abstract
INTRODUCTION KISS1 play an essential role in human reproductive functions by regulating the hypothalamic-pituitary-gonadal axis. Loss-of-function mutations in this gene have been frequently identified in patients with different reproductive disorders. We hypothesised links between KISS1 polymorphisms and polycystic ovary syndrome (PCOS). MATERIALS AND METHODS In order to find links between KISS1 polymorphisms rs4889 C > G, rs12998 G > A, and rs35431622 A > G with PCOS, 770 blood samples were obtained from 385 control and 385 PCOS women. DNA was extracted, and genotyped for KISS1 variants by PCR. RESULTS rs12998 G > A was linked to PCOS in dominant (p < 0.001), recessive (p < 0.001), co-dominant (p < 0.001), and allelic models (p < 0.001). In addition, rs4889 C > G was linked in recessive, dominant, co-dominant, and allelic models (p < 0.001). rs35431622 A > G was not linked to PCOS. Further analysis indicated that C-G-G haplotype was more common and G-A-G haplotype was less prevalent in cases compared with controls. CONCLUSION KISS1 variants rs12998 G > A and rs4889 C > G may be linked to the pathophysiology of PCOS.

Abstract
The importance of new effective treatment methodologies for human immunodeficiency virus (HIV) is undeniable for the medical society. Viral protein U (Vpu), one of the disparaged accessory proteins of HIV, is responsible for the dissemination of viral particles, and HIV mutants lacking Vpu protein have remarkably reduced pathogenicity. Here, we explored the marine natural products to find the leading structures which can potentially inhibit the activity of Vpu in silico. To fulfill this goal, we set up a virtual screening based on molecular docking to evaluate the binding capacity of different marine products to Vpu. For validation, we used molecular dynamics simulation and monitored the root mean square deviation value and binding interactions. The results were intriguing when we realized that the hit compounds (phlorotannins) had previously been identified as reverse transcriptase and HIV protease inhibitors. This research inaugurates a new road to combat HIV by multifaceted mode of action of these marine natural products without putting the normal cells in jeopardy (with their safe toxicological profile).

Abstract
The development of drug resistance is one of the most significant challenges of the current century in the pharmaceutical industry. Superinfections, cancer chemoresistance, and resistance observed in many non-infectious diseases are nullifying the efforts and monetary supplies, put in the advent of new drug molecules. Millions of people die because of this drug resistance developed gradually through extensive use of the drugs. Inherently, some drugs are less prone to become ineffective by drug resistance than others. Covalent inhibitors bind to their targets via a biologically permanent bound with their cognate receptor and therefore display more potent inhibiting characteristics. Suicide inhibitors or mechanism-based inhibitors are one of the covalent inhibitors, which require a pre-activation step by their targeting enzyme. This step accrues their selectivity and specificity with respect to other covalent inhibitors. After that pre-activation step, they produce an analogue of the transition state of the catalytic enzyme, which is practically incapable of dissociating from the enzyme. Suicide inhibitors, due to their high intrinsic affinity toward the related enzyme, are resistant to many mechanisms involved in the development of drug resistance and can be regarded as one of the enemies of this scientific hurdle. These inhibitors compete even with monoclonal antibodies in terms of their cost-effectiveness and efficacy.
