Abstract
BACKGROUND AND OBJECTIVE Endometriosis (EM) involves the peripheral nervous system and causes chronic pain. Sensory nerves innervating endometriotic lesions contribute to chronic pain and influence the growth phenotype by releasing neurotrophic factors and interacting with nearby immune cells. Calcitonin gene-related peptide (CGRP), a pain-signaling neurotransmitter, has a significant role. This study examines the effect of Dienogest (DNG), a hormone therapy used for managing EM -related pain, on serum CGRP levels in EM patients. MATERIALS AND METHODS The Visual Analog Scale (VAS) assessed pain in diagnosed EM. INDIVIDUALS Serum samples were obtained to measure CGRP concentration. Participants received a 2 mg/day oral dose of DNG for six months as prescribed treatment. Additional serum samples were collected after this period to measure CGRP levels. RESULTS In the EM group, 6.7%, 33.3%, and 20% had ovarian EM, ovarian plus uterosacral, and ovarian plus bladder, respectively. The EM group showed higher CGRP serum levels than the control group (80.53 ± 16.13 vs. 58.55 ± 6.93, P < 0.0001). Still, after drug administration, CGRP serum levels significantly decreased compared to pre-treatment levels (69.66 ± 11.53 vs. 80.53 ± 16.13, P < 0.05). The EM group showed higher pain compared to the control group (7.93 ± 1.58 vs. 0.13 ± 0.35, P < 0.0001), but after drug administration, pain significantly decreased compared to pre-treatment levels (1.00 ± 2.00 vs. 7.93 ± 1.58, P < 0.05). CONCLUSION DNG administration reduces pain and serum CGRP levels in EM patients, offering the potential for innovative treatments and tailored options. Understanding neurotransmitter roles and drug effects can aid in discovering more effective modulators for these pathways.

Abstract
OBJECTIVE NOD-like receptor pyrin domain-containing 3 (NLRP3) is a cytosolic multi-protein complex that induces inflammation and is negatively regulated by progesterone. Previous researches have reported abnormal induction of reactive oxygen species (ROS) and progesterone resistance in endometriosis (EM). Since progesterone regulates ROS level and, consequently, inflammation, our objective is to investigate whether dienogest (DNG) regulates NLRP3 and whether the regulation of NLRP3 inflammasome by DNG in the blood plasma of patients with EM can affect oxidant and antioxidant markers. METHODS Plasma samples were obtained from control and EM patients experiencing pain symptoms to measure the level of NLRP3, oxidants, and antioxidants. Subsequently, these patients were given oral DNG 2 mg/day for six months for drug treatment. After six months, plasma samples were collected from the patients for re-examination. RESULTS The findings indicate that DNG reduced NLRP3 concentration and oxidant production while increasing antioxidant production in blood plasma. By reducing NLRP3, DNG was able to alleviate inflammation and pain caused by inflammation in EM patients. CONCLUSION In conclusion, the use of DNG in EM patients resulted in a decrease in NLRP3 concentration in the patient's plasma. Furthermore, this effect was enhanced by balancing oxidant/antioxidant levels, which may contribute to reducing inflammation associated with EM.

Abstract
BACKGROUND Frailty syndrome is a state of increased vulnerability to stressors, marked by lowered physical strength and increased dependence on others. The well-established changes in gut microbiota associated with old age suggest a probable relationship between gut microbiota and frailty. METHODS AND RESULTS This study was aimed at finding the relationship between gut microbiota and frailty syndrome, by comparing the sociodemographic data and the gut microbiota profiles of 23 non-frail and 14 frail elderly individuals. We used the quantitative polymerase chain reaction method (qPCR) to determine the bacterial loads of Bifidobacteria, Lactobacillus, Bacteroidetes, Prevotella, and Escherichia coli in stool samples from test subjects. We discovered a significant increase in the bacterial load of Prevotella in frail elderly individuals aged 70 or above. Other bacterial loads and ratios were not significantly different between the two groups. CONCLUSIONS More comprehensive studies with larger sample sizes and encompassing a wider range of inflammation-related bacteria need to be performed to discover the existence and exact nature of these relations.

Abstract
Innate immunity is the first line of the host immune system to fight against infections. Natural killer cells are the innate immunity lymphocytes responsible for fighting against virus-infected and cancerous cells. They have various mechanisms to suppress viral infections. On the other hand, viruses have evolved to utilize different ways to evade NK cell-mediated responses. Viruses can balance the response by regulating the cytokine release pattern and changing the proportion of activating and inhibitory receptors on the surface of NK cells. Exosomes are a subtype of extracellular vesicles that are involved in intercellular communication. Most cell populations can release these nano-sized vesicles, and it was shown that these vesicles produce identical outcomes to the originating cell from which they are released. In recent years, the role of NK cell-derived exosomes in various diseases including viral infections has been highlighted, drawing attention to utilizing the therapeutic potential of these nanoparticles. In this article, the role of NK cells in various viral infections and the mechanisms used by viruses to evade these important immune system cells are initially examined. Subsequently, the role of NK cell exosomes in controlling various viral infections is discussed. Finally, the current position of these cells in the treatment of viral infections and the therapeutic potential of their exosomes are reviewed. Video Abstract.

Abstract
Background and Aim Timely detection of outbreaks is one of the main purposes of the health surveillance system. The presence of appropriate methods in the detection of outbreaks can have an important role in the timely detection of outbreaks. Because of the importance of this issue, this study aimed to assess the performance of discrete wavelet transform (DWT) based methods in detecting influenza outbreaks in Iran from January 2010 to January 2020. Methods All registered influenza-positive virus cases in Iran from January 2010 to January 2010 were obtained from the FluNet web base tool, the World Health Organization website. The combination method that includes DWT and Shewhart control chart was used in this study. All analyses were performed using MATLAB software version 2018a Stata software version 15. Results The Mean ± SD and median of reported influenza cases from January 2010 to January 2020 was 36 ± 108 and four cases per week. The combination of the DWT and Shewhart control chart with K = 0.25 had the most sensitivity. The most specificity in the detection of nonoutbreak days was seen in the combination of DWT and Shewhart control chart with K = 1.5, K = 1.75, and K = 2, respectively. The combination of DWT and Shewhart control chart with K = 0.5 had the best performance in the detection of outbreaks (sensitivity = 0.64, specificity: 0.90, Youden index: 0.54, and area under the curve [AUC]: 0.77). Conclusion The DWT-based method in detecting influenza outbreaks has acceptable performance, but it is recommended that this method's performance be assessed in detecting outbreaks of other infectious diseases.

Abstract
Since the PLAGL1 (ZAC1) gene is expressed in the human endometrium. It may be involved in the etiology of endometrial disorders by its abnormal regulation and expression. This study aimed to investigate the Zac1 gene and related microRNA and LncRNA and its alterations in patients with endometriosis. Blood plasma, ectopic (EC) and eutopic (EU) endometrial samples were gathered from 30 patients with endometriosis and 30 healthy fertile women, and the Q-PCR technique was used to determine the expression level of Zac1 mRNA and microRNAs (miR-1271-5p, hsa-miR-490-3pin) and LncRNAs (TONSL-AS1 TONSL, KCNQ1OT1 KCNQ1). According to the results, the Zac1 gene and KCNQ1OT1 KCNQ1, TONSL-AS1 TONSL LncRNA expression were significantly decreased in the endometriosis group versus the control group (P < 0.05). MiR-1271-5p and hsa-miR-490-3pin microRNA expression were significantly raised in the endometriosis group as opposed to the control group (P < 0.05). In summary, this research for the first time revealed that identifying Zac1 expression provides us with new indicators for evaluating endometriosis.

Abstract
The present study was conducted to monitor the genotypes of circulating species A rotavirus (RVA) in Iran and investigate genetic linkages between specific RVA VP7, VP4, VP6, and NSP4 segments. For this purpose, 48 RVA strains were detected during the 2021-2022 seasons. The two combinations of G9P[4] and G9P[8] RVA strains were predominant. However, several other combinations of RVA also were detected. Based on the distribution of I and E genotypes (46 strains) with respect to G and P, the most common strains were G9P[4]-I2-E2 (19.5%), G9P[4]-I2-E1 (6.5%), G9P[4]-I1-E1 (4.3%), G9P[8]-I1-E1 (19.5%), and G9P[8]-I2-E2 (10.9%), which were followed by several other combinations of G and P RVA strains with different pattern of I-E genotypes and also emerging, rare and uncommon strains. The present study described the continued circulation of G9 strains with the emergence of uncommon G9P[4] and G9P[8] reassortants with three and two different I-E genotypes, respectively, which have not been reported previously in Iran. Our findings indicated that these uncommon strains exhibited a unique genotype pattern comprising a mixture of genogroup 1 and 2 genes and suggest the need for further analysis of rare, uncommon, and emerging strains of RVA at all 11 gene segments to determine intergenogroup and intragenotype reassortments.

Abstract
BACKGROUND Rotaviruses are the cause of acute gastroenteritis and severe diarrheal diseases in children worldwide. Children under the age of five are more susceptible to rotavirus infections. Due to such as the lack of effective drugs and supportive therapy only, the development of new antiviral agents against rotaviruses is required. Multi-drug-resistant Acinetobacter baumannii is also one of the most challenging Gram-negative bacteria to control and treat due to its antibiotic resistance, particularly in intensive care units. OBJECTIVE This study aimed to investigate the activity of zinc oxide nanoparticles against human rotavirus and multi-drug resistant Acinetobacter baumannii. METHODS The standard 50% tissue culture infectious dose method and the real-time polymerase chain reaction assay were used to investigate the effects of zinc oxide nanoparticles on rotaviruses. The well diffusion and the minimum inhibitory concentration method were used to assess the antibacterial activity of zinc oxide nanoparticles against Acinetobacter baumannii. RESULTS 300 μg/ml of zinc oxide nanoparticles demonstrated the highest anti-rotavirus effects, resulting in a 3.16 logarithmic decrease in virus infectious titer, and a four-unit increase in the cycle threshold value of the real-time polymerase chain reaction assay compared to the untreated control (P value <0.001 and P value = 0.005, respectively). The diameter of the inhibition zone of zinc oxide nanoparticles solution against Acinetobacter baumannii was 17 mm. The minimum inhibitory concentration results of the zinc oxide nanoparticles solution against Acinetobacter baumannii was 1.56 mg/ml. CONCLUSION Our findings showed that zinc oxide nanoparticles could be considered a promising antimicrobial compound.

Abstract
Background The emergence of multidrug resistance among nosocomial pathogens has prompted researchers to look for new antibacterial sources. Metal nanoparticles and probiotic products have attracted the attention of researchers. However, combination therapy is an attractive alternative in this field. Objectives This study evaluated the antibacterial activity and toxicity of Zinc Oxide nanoparticles (ZnO-NPs) combined with cell-free supernatant (CFS) of Lactobacillus plantarum and Lactobacillus acidophilus alone and in a novel mixture. Methods Antibacterial effects and cytotoxic properties of ZnO-NPs, CFS of L. plantarum (SLP), and CFS of L. acidophilus (SLA) were determined alone and in a mixture against ESKAPE strains. In addition, the viability percentage of the cells was evaluated after exposure to these agents. Results Antibacterial mixtures (ZnO-NPs with SLP or ZnO-NPs with SLA) demonstrated synergistic and additive effects against Pseudomonas aeruginosa (FIC≤0.75), Acinetobacter baumannii (FIC = 1), and Escherichia coli (FIC≤0.75). The viability percentage of the cells after 24 h of exposure to a mixture of ZnO-NPs and SLA (about 50%) was more than when the cells were exposed to ZnO-NPs alone (about 30%) at the same concentration. Conclusions A mixture of ZnO-NPs and CFS of probiotics can be an alternative to antibiotics, with more effectiveness and fewer side effects.

Abstract
OBJECTIVE One of the challenges in gene therapy is the transfer of the gene to the target cell. MicroRNAs (miRNAs) regulate gene expression after transcription by binding directly to the messenger and play a vital role in cell behaviors and the pathogenesis of some diseases. This study was aimed at developing poly (lactic-co-glycolic acid) (PLGA)- based nanoparticles (NPs) for gene delivery to endometriotic cyst stromal cells (ECSCs). MATERIALS AND METHODS In this experimental study, endometriosis cells were isolated from women with severe endometriosis (DIE) and digested by the enzymatic method (40 μg/ml DNAase I and 300 μg/ml collagenase type 3). PLGA-based NPs were synthesized and characterized. The size of sole PLGA NPs and PLGA/miRNA were 60 ± 4 nm and 70 ± 5.1 nm respectively. Poly lactic-co-glycolic-based NPs were used as vector carriers for miRNA 503 transfection in endometriosis cells. The cells were divided into the five groups of control and four doses (25, 50, 75, and 100 μm) of miRNA 503/PLGA at 12, 24, 48, and 72 hours. Viability and apoptosis were evaluated by the MTT assay and Annexin Kits. Data were analyzed by one-way analysis of variance. RESULTS The results show that the size of PLGA/miRNA complex with dynamic light scattering (DLS) was 70 ± 5.1 nm and zeta potential values of the PLGA/PEI/miRNA complexes were 27.9 mV. Based on the MTT assay results, the optimal dose of miRNA 503/PLGA was 75 μm, at which the viability of ECSCs was 52.6% ± 1.2 (P≤0.001), and the optimal time was 48 hours. The apoptotic rates of ECSCs treated with PLGA/miRNA503 (34.75 ± 4.9%) were significantly higher than those of ECSCs treated with PLGA alone (3.35 ± 2.58%, P≤0.01). CONCLUSION Cell death increased with increasing the concentration of miRNA; thus, it can be suggested as a treatment for endometriosis.

Abstract
Trichomonas vaginalis is a protozoan parasite that causes trichomoniasis with worldwide distribution. This study evaluated actin genotypes of T. vaginalis isolates using PCR-RFLP and sequence analysis in Tehran, Iran. Overall, 850 vaginal samples were collected from women admitted to hospitals affiliated with the Iran University of Medical Sciences in Tehran from 2020-to 2021. The samples were examined by wet mount and cultured. The parasites were harvested, and PCR-RFLP was performed using three endonuclease enzymes of HindII, MseI, and RsaI on all T. vaginalis isolates. Digestion patterns were then compared, and the genotype of these isolates was defined. The PCR products were sequenced. Overall, 12 (1.4%) isolates of T. vaginalis were identified from 850 vaginal samples collected. The most common genotypes were genotype E, seven (58.3%) and genotype G, three (25%), followed by genotype I, two (%16.7), using PCR-RFLP patterns and sequencing. No pattern indicative of mixed infection was found. PCR-RFLP is a proper technique to detect different T. vaginalis isolates, and noticeable polymorphism was found between isolates. Genotype E was the most common genotype in the studied group. The phylogenetic analysis indicated the T. vaginalis genotype E isolates in a distinct group compared to the genotypes G and I that evolved from a common ancestor.

Abstract
The purpose of this research was to investigate the gene expression levels of inflammatory cytokines interferon (IFN)γ, tumor necrosis factor (TNF)α, interleukin (IL)1β, IL2, IL6, IL8, and IL17, and anti-inflammatory cytokines IL4, IL10, IFNα, and IFNβ, as well as relevant key transcription factors (TFs), including GATA3, PU1, NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells), IRF3 (interferon regulatory factor 3), BCL6 (B cell lymphoma 6 protein), FOXP3 (forkhead box P3), RORγt, and T-bet (T-box expressed in T cell) in Iranian patients with moderate and severe coronavirus disease 2019 (COVID-19). Fifty-six patients with COVID-19, and 25 healthy controls (HCs) age and sex matched were investigated. Based on the interim guidance of COVID-19 from the World Health Organization, the patients were classified into 33 moderate and 23 severe patients with COVID-19. The gene expression levels of cytokines and relevant TFs were quantified in peripheral blood mononuclear cells by quantitative real-time polymerase chain reaction (qRT-PCR). The gene expression levels of TFs RoRγ (RAR-related orphan nuclear receptor γ), NF-κB, and T-bet were significantly higher in patients with COVID-19 compared with HCs. Furthermore, the gene expression levels of cytokines, including IL2, IFNγ, IL6, TNFα, IL1β, IL8, and IL17, were significantly higher in patients with COVID-19 than HCs. However, there was a significant increase for IL6, TNFα, and IL17 in severe compared with moderate patients with COVID-19. Finally, The Spearman correlation analysis revealed a significantly positive correlation for IL6 and TNFα, IL6 and IL2, IL6, IFNγ, and IL2 and IFNγ. These data suggest that expression of IL6, TNFα, and IL17 as well as the synergic effect of elevated values of IL2 and IFNγ should be considered in the treatment and management of patients with severe COVID-19.

Abstract
BACKGROUND: Human parvovirus B19 (B19V) is one of the blood-borne viruses. The virus can be transmitted to susceptible individuals by blood or blood products. The virus is not associated with significant disease in general population, while people with underlying problems such as immunodeficiency can cause anemia and arthritis. The current systematic review and meta-analysis aimed to estimate the overall prevalence of B19V DNA, anti-B19V IgG, and anti-B19V IgM antibodies in blood donors worldwide. METHODS: A systematic search was carried out in online databases for relevant studies from inception until March 30, 2019. Study selection was performed based on predesigned eligibility criteria. The proportion of B19V DNA, anti-B19V IgG, and anti-B19V IgM antibodies were pooled using the inverse variance method. All statistical analyses were performed using the R version 3.5.3, package “meta.” RESULTS: According to the random-effects model, the pool prevalence of B19V DNA, anti-B19V IgM, and anti-B19V IgG among blood donors was calculated to be 0.4% (95% confidence interval [CI] =0.3%–0.6%), 2.2% (95% CI = 1.3%–3.7%), and 50.1% (95% CI = 43.1%–57.1%), respectively. CONCLUSION: For the transmission of B19V through blood, the presence of the virus genome is required, and the present study showed that the prevalence of the virus genome in blood donors is <1%. Therefore, there is no need to screen donated blood for B19V infection.

Abstract
The purpose of this study was to compare the effectiveness of Atazanavir/Ritonavir/Dolutegravir/Hydroxychloroquine and Lopinavir/Ritonavir/Hydroxychloroquine treatment regimens in COVID‐19 patients based on clinical and laboratory parameters. We prospectively evaluated the clinical and laboratory outcomes of 62 moderate to severe COVID‐19 patients during a 10‐day treatment plan. Patients were randomly assigned to either KH (receiving Lopinavir/Ritonavir [Kaletra] plus Hydroxychloroquine) or ADH (receiving Atazanavir/Ritonavir, Dolutegravir, and Hydroxychloroquine) groups. During this period, clinical and laboratory parameters and outcomes such as intensive care unit (ICU) admission or mortality rate were recorded. Compared to the KH group, after the treatment period, patients in the ADH group had higher activated partial thromboplastin time (aPTT) (12, [95% confidence interval [CI]: 6.97, 17.06), p = <0.01), international normalized ratio (INR) (0.17, [95% CI: 0.07, 0.27), p = <0.01) and lower C‐reactive protein (CRP) (−14.29, (95% CI: −26.87, −1.71), p = 0.03) and potassium (−0.53, (95% CI: −1.03, −0.03), p = 0.04) values. Moreover, a higher number of patients in the KH group needed invasive ventilation (6 (20%) vs. 1 (3.1%), p = 0.05) and antibiotic administration (27 (90%) vs. 21(65.6), p = 0.02) during hospitalization while patients in the ADH group needed more corticosteroid administration (9 (28.1%) vs. 2 (6.7%), p = 0.03). There was no difference in mortality rate, ICU admission rate, and hospitalization period between the study groups. Our results suggest that the Atazanavir/Dolutegravir treatment regimen may result in a less severe disease course compared to the Lopinavir/Ritonavir treatment regimen and can be considered as an alternative treatment option beside standard care. However, to confirm our results, larger‐scale studies are recommended. Despite the use of many drugs and efforts in controlling the COVID‐19 pandemic, no definitive cure has been found yet. We compared the effectiveness of Atazanavir/Ritonavir/Dolutegravir/Hydroxychloroquine and Lopinavir/Ritonavir/Hydroxychloroquine treatment regimens in hospitalized COVID‐19 patients. Clinical and laboratory results show that Atazanavir/Dolutegravir regimen is more effective in ameliorating the severity of COVID‐19 and may be a useful addition to treatment options for COVID‐19 alongside standard care.

Abstract
BACKGROUND To our knowledge, data on the effects of vitamin D supplementation on clinical symptoms and metabolic profiles in patients with endometriosis are limited. This study was conducted to determine the effects of vitamin D supplementation on clinical symptoms and metabolic profiles in patients with endometriosis. METHODS The current randomized, double-blind, placebo-controlled trial was conducted among 60 patients (aged 18-40 years old) with endometriosis. Participants were randomly allocated into two groups (30 participants each group) to receive either 50,000 IU vitamin D or placebo each 2 weeks for 12 weeks. RESULTS Vitamin D supplementation significantly decreased pelvic pain (β - 1.12; 95% CI, -2.1, -0.09; p=.03) and total-/HDL-cholesterol ratio (β - 0.29; 95% CI, -0.57, -0.008; p=.04) compared with the placebo. Moreover, vitamin D intake led to a significant reduction in high-sensitivity C-reactive protein (hs-CRP) (β - 0.64 mg/L; 95% CI, -0.97, -0.30; p<.001) and a significant increase in total antioxidant capacity (TAC) (β 47.54 mmol/L; 95% CI, 19.98, 75.11; p=.001) compared with the placebo. CONCLUSIONS Overall, our study demonstrated that vitamin D intake in patients with endometriosis resulted in a significant improvement of pelvic pain, total-/HDL-cholesterol ratio, hs-CRP and TAC levels, but did not affect other clinical symptoms and metabolic profiles.

Abstract
BACKGROUND Toxoplasmic chorioretinitis may occur as a result of acquired toxoplasmosis or reactivated congenital toxoplasmosis. In this study, Toxoplasma gondii bradyzoite genes along with the B1 gene were evaluated to detect T. gondii DNA in serum and peripheral blood mononuclear cells (PBMCs) of patients with toxoplasmic chorioretinitis. METHODS Blood samples were collected from 10 patients (7 cases of active chorioretinal lesions and 3 cases of old chorioretinal scars). The genomic DNA was extracted from the patients' serum and PBMCs and a polymerase chain reaction (PCR) assay was performed using bradyzoite genes along with B1. The subjects were also evaluated in terms of the T. gondii antibodies. RESULTS The PCR results were positive in four of seven patients (57.1%) with active ocular toxoplasmosis lesions. In three patients (42.8%), the PCR results were positive for MAG-1 and SAG-4 and in one patient (14.3%) the PCR results were only positive for the B1 gene. The PCR results were positive only in the PBMCs, whereas they were negative in the serum samples. Two patients with positive PCR results showed high Toxoplasma immunoglobulin G (IgG) antibody titres. However, none of the patients showed positive Toxoplasma IgM antibodies. CONCLUSIONS The PBMCs are suitable for evaluating toxoplasmic chorioretinitis. The present results showed that PCR with bradyzoite genes is useful in the diagnosis of toxoplasmic chorioretinitis in PBMCs.

Abstract
In the post rotavirus vaccine era, norovirus (NoV) plays an increasingly important role in epidemic and sporadic gastroenteritis among children. This study was designed to provide an updated meta-analytic review of the prevalence of NoV among paediatric patients with gastroenteritis and to clarify the relationship between NoV infection and gastroenteritis. Systematic searches of the literature for potentially relevant studies were carried out from 1 January 2015 to 29 May 2020. The inverse variance method was chosen for weighting of the studies, and the random-effects model was used to analyse data. To determine the association between NoV infection and gastroenteritis in children, pooled odds ratio (OR) and its 95% confidence interval (CI) were computed for case-control studies. The pooled prevalence of NoV infection among 12,0531 children with gastroenteritis from 45 countries across the world was 17.7% (95% CI: 16.3%-19.2%). There were 28 studies with a case-control design, and the pooled prevalence of NoV infection among 11,954 control subjects was 6.7% (95% CI: 5.1%-8.8%). The pooled OR of the association of NoV infection and gastroenteritis was 2.7 (95% CI: 2.2-3.4). The most common NoV genotypes were GII.4 (59.3%) and GII.3 (14.9%). The highest frequency of NoV was found in the age group below 1 year. Our findings indicated a substantial burden of gastroenteritis caused by NoV globally, with GII.4 and GII.3 the major genotypes responsible for the majority of NoV-associated gastroenteritis cases among children. Younger age and male sex can be considered risk factors for NoV-associated gastroenteritis among children.

Abstract
Aim: To investigate the association between different viral infections and the development of Kawasaki disease (KD) in children. Materials & methods: Electronic databases were searched for relevant studies published from inception to May 2020. The pooled odds ratios (ORs) of the association of different viral pathogens with KD were estimated using a random-effects model weighted by the inverse variance method. Results: The strongest associations were found between KD and human parvovirus B19 viremia (OR = 41.05; 95% CI: 5.13–328.28; I-square = 0%), EBV IgM seropositivity (OR = 7.18; 95% CI: 3.65–14.12, I-square = 0%) and human herpesvirus-6 IgG seropositivity (OR = 5.83; 95% CI: 1.06–32.01). Conclusion: Human parvovirus B19, EBV and human herpesvirus-6 are highly suspected to be key contributors to the development of KD.

Abstract
INTRODUCTION MicroRNAs (miRNAs), as a family of non-coding RNAs, have opened a new window in cancer biology and transcriptome. It has been revealed that miRNAs post-transcriptionally regulate the gene expression and involve in colorectal cancer (CRC) development and progression. Our aim was to examine the differential expression of miRNAs in a CRC and to correlate their expression levels with mRNA levels of CRC-related genes (K-ras, APC, p53). MATERIALS AND METHODS Seventy-two colorectal tumor tissues from patients with newly diagnosed CRC and 72 matched normal adjacent tissues were analyzed. Relative expression of seven CRC-related miRNAs (miR-21, miR-31, miR-20a, miR-133b, and miR-145, miR-135b and let-7g) and three CRC-related genes (K-ras, APC, p53) was detected using the SYBR Green quantitative real-time PCR technique. The correlation between gene expression levels and clinicopathological features was evaluated. RESULTS Our results showed a significant difference between the two groups for the expression level of miR-21, miR-31, miR-145, and miR-20a (P < 0.001). Also, a significant difference between the two groups for the expression level of K-ras was found (P < 0.001). Further analysis revealed an inverse significant correlation between miR-145 and K-ras (R2 = 0.662, P < 0.001), while a positive correlation was observed between miR-21 and K-ras (R2 = 0.732, P < 0.001). CONCLUSION Dysregulation of miRNAs and correlation with molecular signaling pathways designated a biological role for miRNAs in various cellular mechanisms underlying CRC. On the other hand, the pattern of miRNAs expression and its correlation with transcriptional status are helpful to discovery biomarkers and design therapeutics for CRC.

Abstract
BACKGROUND AND OBJECTIVES Cytomegalovirus (CMV) constitutes the most common viral cause of congenital infections in newborns worldwide. There are a significant number of asymptomatic newborns with congenital CMV infection in Iran, which may develop long-term sequelae of infection. Unfortunately, limited data exsists from Iran on the rate of congenital CMV infection among neonates. The current study was aimed to investigate the prevalence of congenital CMV infection among Iranian neonates by testing Guthrie cards. MATERIALS AND METHODS Guthrie cards were collected from infants within 2 weeks of life, and total DNA was extracted from samples by thermal shock and evaluated for CMV DNA using nested-PCR assay. CMV infection in newborns was confirmed through a commercial CMV PCR kit. Infected infants underwent further evaluation at the hospital. RESULTS CMV infection was identified in four of 1174 infants (0.34%) which is approximately 3 cases per 1000 live births. Infected infants were asymptomatic at birth and had a normal hearing status similar to other children. There were no factors in relation with CMV infection among newborns. CONCLUSION According to the results of this study, infected infants with congenital CMV infection could identify at early stage by testing Guthrie cards (within 21 days of life). Furthermore, since there is a lack of CMV knowledge in our population, educating and effective counseling by obstetricians/ gynecologists to the pregnant women are recommended.

Abstract
OBJECTIVE Glioblastoma (GBM) is the most common primary malignant neoplasm of the central nervous system (CNS). Despite the progress in therapeutic strategies such as surgical techniques, radiotherapy, chemotherapy, and targeted therapy, prognosis and therapeutically convenient monitoring tools in patients with GBM has not improved significantly up to now.Therefore, exosomal miRNAs as novel non-invasive biomarkers having high sensitivity and specificity are required to improve diagnosis and to develop new targeted therapy strategies for GBM patients. The aim of the present study was to investigate a novel miRNA signature as a predictive biomarker for diagnosis and measurement of response to therapeutic interventions in plasma of GBM patients versus traumatic brain injury and diffuse low-grade astrocytoma (LGA) patients. PATIENTS AND METHODS Plasma exosomal-microRNAs were isolated from GBM (n = 25), LGA (n = 25), and head trauma patients (n = 15) as non-glioma control from March 2017 to June 2018 in Department of Neurosurgery at Rasoul-e-Akram Hospital. Through a bioinformatics analysis, we used Miranda, TargetScan, mirBase, DIANA-microT-CDS, and KEGG database as well as microarray data analysis from GEO for microRNA candidates. Finally, miR-210, miR-185, miR-5194, and miR-449 were selected among those miRNAs because they were recorded to target the maximum number of genes in EGFR and c-MET signaling pathways. Then, exosomal microRNAs were extracted from plasma of patients and quantitated by locked nucleic acid real-time PCR in GBM, LGA, and trauma patients. RESULTS This result is the first report on the role of circulating miR-185, miR-449, and miR-5194 in GBM compared to LGA and trauma. The plasma expression of miR-210 as an oncogenic miR was upregulated in GBM and LGA groups (P < 0.0001). Otherwise, miR-185, miR-5194, and miR-449 were significantly downregulated (P ≤ 0.05) in GBM and LGA compared to trauma patients. There was no significant downregulation in the expression of miR-185 between GBM and LGA, while the expression of miR-5194 (P ≤ 0.05) and miR-449 (P ≤ 0.05) was significantly decreased in GBM patients compared with LGA. CONCLUSIONS These results indicate that the levels of miR-210, miR-449, and miR-5194 are a promising diagnostic and prognostic biomarker positively correlated with histopathological grade and invasiveness of GBM. These findings imply that circulating microRNA can be potentially used as novel biomarkers for glioma that might be beneficial in clinical management of glioma patients.

Abstract
INTRODUCTION Non-coding RNAs have opened a new window in cancer biology. MicroRNAs (miRNAs), as a family of non-coding RNAs, play an important role in the gene regulation. The aberrant expression of these small molecules has been documented to involve in colorectal cancer (CRC) pathogenesis. This study aimed to examine the expression of miRNAs in CRC and to correlate their expression levels with histological markers (Ki-67 and CD34). MATERIALS AND METHODS Tumor tissues and matched normal adjacent tissues were collected from 36 patients with newly diagnosed CRC. Immunohistochemical (IHC) staining of tumor tissues was performed for Ki-67 (proliferation) and CD34 (angiogenesis) markers, and the immunoexpression staining scores were obtained. A polyadenylation SYBER Green quantitative real-time PCR technique was used to quantify the expression of a panel of five CRC-related miRNAs (hsa-miR-21, 31, 20a, 133b, and 145). Histopathological (H) scores and miRNA expression levels were correlated with clinicopathological features including the degree of differentiation, staging, and lymphovascular invasion. RESULTS Our results showed the significant difference between the two groups for the expression level of hsa-miR-21, hsa-miR-31, hsa-miR-145, and miR-20a (P < 0.001), but not for hsa-miR-133b (P = 0.57). Further analysis revealed an inverse significant correlation between hsa-miR-145 and Ki-67 (r = - 0.942, P < 0.001). While a positive correlation was observed between hsa-miR-21 and Ki-67 (r = 0.920, P < 0.001), and hsa-miR-21 and CD34 (r = 0.981, P < 0.001). Also, a positive correlation between hsa-miR-31 and Ki-67 (r = 0.913, P < 0.001), hsa-miR-31 and CD34 (r = 0.798, P < 0.05), hsa-miR-20a and Ki-67 (r = 0.871, P < 0.001), and hsa-miR-20a and CD34 (r = 0.890, P < 0.001) was found. CONCLUSION Dysregulation of miRNAs and correlation with molecular histopathology indicate a biological role for miRNAs in various cellular processes including cell proliferation and angiogenesis in CRC development. On the other hand, the pattern of miRNA expression and its correlation with histological markers are potentially valuable to apply as diagnostic biomarkers for CRC.

Abstract
Background: It has been widely acknowledged that change and constant modification is the key to survive for any organization among their rivals. Since success in implementing changes in the organization strongly depends on the organizational culture, this study aims to assess the organizational culture in Iran University of Medical Sciences. The results of this study can be beneficial in initiating a movement towards the third – and fourth generation of universities.
Methods: This study is descriptive-correlational. The Organizational Culture Assessment Instrument (OCAI) was employed to collect data. A questionnaire was sent to the faculty members via email, and the responses were collected and analyzed.
Results: Out of the 982 faculty members, 189 participated (20.7%) in this study. Analysis showed that the organizational culture of the university is congruent and harmonious and in the current state, it is primarily hierarchical (31%) and market-oriented (28%) with emphasis on stability and control in the organization. Whereas, faculty members tend to move the organizational culture of the university towards adhocracy (30%) and clan culture (29%).
Conclusion: University administrators must strengthen the culture of innovation and creativity based on the needs of the market. This only can be achieved by supporting teamwork in their move towards desired change.

Abstract
BACKGROUND Human papilloma virus (HPV) is one of the major public health problems and the main causes of cervical cancer. The prevalence HPV infection in developing countries with low financial resources is high. OBJECTIVE This study aimed to determine the relative frequency of HPV genotypes and its sociodemographic characteristics in women referred to a general hospital in Tehran, Iran from 2014-2015. MATERIALS AND METHODS This cross-sectional study was performed in 400 women with Pap smear samples, referring to to a general hospital in Tehran, Iran from 2014-2015. The detection of 28 HPV genotypes was performed by using the Multiplex PCR technique. The sociodemographic survey was conducted for each HPV positive woman. RESULTS HPV-positive infection was detected in 155 (38.75%) women aged 17-85 years. HPV 16 (19.1%) was the most prevalent type, followed by HPV 39 (12.5%) and HPV 18 (8.9%). The highest rate of HPV infection was observed at the age of 36 years (7.7%). The level of education and economic situation of each woman were showed most of HPV-positive women had a high school diploma (34.6%) and average economic situation (67,9%). 60.9% of these women were a housewife, and 67.3% lived in the capital . CONCLUSION Determination of HPV genotype and risk factor related to HPV infection in each geographical region can lead to the production of effective vaccines against the HPV virus. It can also be useful for disease management and high sensitivity diagnosis of cervical intraepithelial neoplasia.

Abstract
Background Fluoroquinolone resistance in Pseudomonas aeruginosa may be due to efflux pump overexpression and/or target mutations. We designed this study to investigate the efflux pump mediated fluoroquinolone resistance and check the increasing effectiveness of fluoroquinolones in combination with an efflux pumps inhibitor among P. aeruginosa isolates from burn wounds infections. Materials and Methods A total of 154 consecutive strains of P. aeruginosa were recovered from separate patients hospitalized in a burn hospital, Tehran, Iran. The isolates first were studied by disk diffusion antibiogram for 11 antibiotics and then minimum inhibitory concentration (MIC) experiments were performed to detect synergy between ciprofloxacin and the efflux pump inhibitor, carbonyl cyanide-m-chlorophenyl hydrazone (CCCP). Then to elucidate the inducing of multi drug resistance due to different efflux pumps activation in Fluoroquinolone resistant isolates, synergy experiments were also performed in random ciprofloxacin resistant isolates which have overexpressed efflux pumps phenotypically, using CCCP and selected antibiotics as markers for Beta-lactams and Aminoglycosides. The isolates were also tested by polymerase chain reaction (PCR) for the presence of the MexA, MexC and MexE, which encode the efflux pumps MexAB-OprM, MexCD-OprJ and MexEF-OprN. Results Most of the isolates were resistant to 3 or more antibiotics tested. More than half of the ciprofloxacin resistant isolates exhibited synergy between ciprofloxacin and CCCP, indicating the efflux pump activity contributed to the ciprofloxacin resistance. Also increased susceptibility of random ciprofloxacin resistant isolates of P. aeruginosa to other selected antibiotics, in presence of CCCP, implied multidrug extrusion by different active efflux pump in fluoroquinolones resistant strains. All of Ciprofloxacin resistant isolates were positive for MexA, MexC and MexE genes simultaneously. Conclusion In this burn hospital, where multidrug resistant P. aeruginosa isolates were prevalent, ciprofloxacin resistance and multidrug resistance due to the overexpression of fluoroquinolones mediated efflux pumps has also now emerged. Early recognition of this resistance mechanism should allow the use of alternative antibiotics and use an efflux pumps inhibitor in combination with antibiotic therapy.

Abstract
Persistent infection of the human papillomaviruses (HPV) has been shown to result in cervical cancer and intraepithelial neoplasia. Early detection and screening programs are essential strategies against cervical cancer. A nanobody is the smallest antigen-binding fragment known and is derived from a camelid heavy-chain antibody. This tiny protein shows high solubility and stability. It can be produced cost-effectively with high yield production. In this study, we enriched a nanobody library against the L1 protein of HPV. Several colons were selected from this enriched library using monoclonal phage-enzyme linked immunosorbent assay (phage-ELISA) and analyzed for identification of nanobody genes. The expression of nanobody fragments was performed in Rosetta gami2. The C74 nanobody that showed strong binding to the L1 protein of HPV16 was selected, purified, and characterized by Western blotting and ELISA. The selected nanobody was tested for sensitivity, specificity, and affinity. A nanobody conjugated to horseradish peroxidase (HRP) was selected and used for detection of L1 protein of HPV16. This study demonstrates that the C74-HRP, due to its specificity and good binding affinity for a specific viral antigen, is a potential diagnostic tool that can be used as a promising reagent for the new generation of HPV diagnosis approaches.

Abstract
The human papillomavirus (HPV) is the main cause of cervical cancer in developing countries. Rapid diagnosis and initiation of treatment of the HPV infection are critical. Various methods have been employed to reduce the immunogenicity of antibodies targeting HPV serotypes. Nanobodies are the smallest fragments of naturally occurring single-domain antibodies with their antigenbinding site compromised into a single domain. Nanobodies have remarkable properties such as high stability, solubility, and high homology to the human VH3 domain. In this study, a phagemid library was employed to enrich for nanobodies against the L1 protein of the human papilloma virus. Binding reactivity of the selected clones was evaluated using phage enzyme-linked immunosorbent assay (phage-ELISA). Finally, two nanobodies (sm5 and sm8) with the best reactivity against the Gardasil vaccine and the purified HPV-16 L1 protein were expressed and purified using a Ni(+)-NTA column. The accuracy of expression and purification of the nanobodies was confirmed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and immunoblotting assays. In vitro studies demonstrated that neutralization was achieved by the selected nanobodies. The ease of generation and unique features of these molecules make nanobodies promising molecules for the new generation of HPV diagnosis and therapy.
