Abstract
OBJECTIVE The inhibition of M1 macrophages may be interesting for targeted therapy with mesenchymal stem cell-derived Exosomes (MSC-EXOs). This study aimed to investigate the stem cells of human exfoliated deciduous teeth-derived EXOs (SHED-MSC-EXOs) effect on regulating the pro- and anti-oxidant indexes and inhibiting M1 macrophage polarization. Besides, an in-silico analysis of SHED-MSC-EXO miRNAs as the highest frequency of small RNAs in the exosomes was performed to discover the possible mechanism. METHODS The flow cytometry analysis of CD80 and CD86 as M1-specific markers confirmed the polarization of macrophages derived from THP-1 cells. After exosome isolation, characterization, and internalization, THP-1-derived M1 macrophages were treated with SHED-MSC-EXOs. M1-specific markers and pro- and anti-oxidant indexes were evaluated. For in-silico analysis of SHED-MSC-EXOs miRNAs, initial miRNA array data of SHED-EXOs is collected from GEO, and the interaction of the miRNAs in M1 macrophage polarization (M1P), mitochondrial oxidative stress (MOS) and LPS-induced oxidative stress (LOS) were analyzed by miRWalk 3.0 server. Outcomes were filtered by 75th percentile signal intensity, score cut-off ≥0.95, minimum free energy (MEF)≤ -20 kcal/mol, and seed = 1. RESULTS It shows a decrease in the expression of CD80 and CD81, a reduction in pro-oxidant indicators, and an increase in the anti-oxidant indexes (P < 0.05). Computational analysis showed that eight microRNAs of SHED-MSC-EXO miRNAs can bind to and interfere with the expression of candidate genes in the M1P, MOS, and LOS pathways simultaneously. CONCLUSION SHED-MSCs-EXOs can be utilized to treat conditions related to M1 macrophage-induced diseases (M1IDs) due to their unique physical properties and ability to penetrate target cells easily.

Abstract
AIM To investigate the impact of niosome nanoparticles carrying umbelliprenin (UMB), an anti-angiogenic and anti-inflammatory plant compound, on the expression of vascular endothelial growth factor (VEGF-A) and connective tissue growth factor (CTGF) genes in a human retinal pigment epithelium (RPE)-like retina-derived cell line. METHODS UMB-containing niosomes were created, optimized, and characterized. RPE-like cells were treated with free UMB and UMB-containing niosomes. The IC50 values of the treatments were determined using an MTT assay. Gene expression of VEGF-A and CTGF was evaluated using real-time polymerase chain reaction after RNA extraction and cDNA synthesis. Niosomes' characteristics, including drug entrapment efficiency, size, dispersion index, and zeta potential were assessed. Free UMB had an IC50 of 96.2 µg/mL, while UMB-containing niosomes had an IC50 of 25 µg/mL. RESULTS Treatment with UMB-containing niosomes and free UMB resulted in a significant reduction in VEGF-A expression compared to control cells (P=0.001). Additionally, UMB-containing niosomes demonstrated a significant reduction in CTGF expression compared to control cells (P=0.05). However, there was no significant reduction in the expression of both genes in cells treated with free UMB. CONCLUSION Both free UMB and niosome-encapsulated UMB inhibits VEGF-A and CTGF genes expression. However, the latter demonstrates significantly greater efficacy, potentially due to the lower UMB dosage and gradual delivery. These findings have implications for anti-angiogenesis therapeutic approaches targeting age-related macular degeneration.

Abstract
BACKGROUND During the coronavirus disease 2019 (COVID-19) pandemic, the simultaneous detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and Influenza A, and Influenza B viruses is essential for rapid differential diagnosis in patients with similar symptoms, especially during "flu season" in the post-pandemic era. So far, several multiplex methods have been approved for the simultaneous detection of SARS-CoV-2, Influenza A, and Influenza B. However, due to the rapid mutation rate of the SARS-CoV-2 genome and the emergence of new variants, existing methods must be improved and updated. METHODS To identify a highly conserved region in the SARS-CoV-2 N-gene, a genomic survey was performed to increase the sensitivity and specificity of primer and probe sets targeting the SARS-CoV-2 genome. The 95% LLOD (95% lower limits of detection) were calculated by probit analysis. A total of 70 predetermined clinical samples using singleplex RT-qPCR assays, were included. The clinical performance of the multiplex RT-qPCR assay was determined and compared with a commercial multiplex kit. The Cohen's kappa coefficient, P-value (McNemar's test), Passing-Bablok regression, and Bland Altman agreement analysis were determined to monitor the agreement of the assays. RESULTS The novel SARS-CoV-2 primer and probe set designed in this assay was able to detect all variants of concern (VOCs) and variants of interest (VOIs) with high analytical and clinical performance. The 95% LLOD for the multiplex RT-qPCR was 20 copies per reaction for the N gene of SARS-CoV-2, 2 copies per reaction for M1 gene of Influenza A and NS1 gene of Influenza B. The diagnostic sensitivity of the multiplex RT-qPCR was 94.4%, 93.7%, and 100% for the detection of SARS-CoV-2, Influenza A, and Influenza B genomes, respectively. Moreover, the specificity was identical (100%) in both assays. According to the agreement analysis results, there was no statistical difference between our multiplex assay and the commercial kit. CONCLUSIONS In this study, we developed a novel in-house made multiplex RT-qPCR assay, with high sensitivity, specificity, and reliability for the diagnosis of SARS-CoV-2 infection in clinical samples. This is valuable during Influenza seasons when influenza co-circulates with SARS-CoV-2, as it saves costs, time, and thus specific and timely treatment of patients.

Abstract
SARS-CoV-2 put a heavy financial burden on the healthcare system, with millions of laboratory-confirmed cases and deaths worldwide in the last 2 years. During the seventh wave of this pandemic, the continuously evolving nature of SARS-CoV-2 resulted in the emergence of new variants that harbor different mutations. Mutations are associated with changes in the virus behavior, including increased transmissibility, increased virulence, and evasion of neutralizing antibodies. Currently, we need detailed and comprehensive genomic information on all SARS-CoV-2 variants. One of the key points in this study was the genome survey of mutation profiles across variants as a genomic data source, to determine the efficiency of RT-qPCR assays. We also used the source to calculate the binding affinity changes of neutralizing antibodies-mutant receptor binding domain (RBD) complexes and determine vaccine efficacy. Our result revealed that the number of nucleotide mismatches is variable in the WHO-recommended primer-probe sets. Mismatches located at the 3' ends of the oligonucleotide, may lead to false-negative results. Only the primer-probe sets designed by the Ministry of Public Health of Thailand were exclusive and cannot detect the omicron variant reliably. Binding affinity changes showed that E484K was more deleterious than other mutations and decreased stability between the mutant RBD protein and neutralizing antibodies. The Omicrons show the highest change in binding affinity which may lead to immune escape and increase transmissibility. Additionally, the 7D6 monoclonal antibody in the 7eam complex could neutralize all variants of SARS-CoV-2. We strongly recommend creating and improving a matrix accuracy by processing a large number of SARS-CoV-2 sequences to update RT-qPCR assays and identified immunogenic residues among conserved RBD. Also, a detail computational analysis is needed to investigate distinctive amino acid substitution patterns which may be foundational in the vaccines. Finally, designing in-vitro studies can help confirm the present study and manage COVID-19 patients.Communicated by Ramaswamy H. Sarma.

Abstract
INTRODUCTION Somatic cell fate transition is now gained great importance in tissue regeneration. Currently, research is focused on heart tissue regeneration by reprogramming diverse cells into cardiomyocyte-like cells. Here, we examined the possible effect of miRNAs on the transdifferentiation of fibroblasts into cardiomyocyte-like cells. METHODS First heart-specific miRNAs were identified by comparing the gene expression profiles of heart tissue to other body tissues using bioinformatic techniques. After identifying heart-specific miRNAs, their cellular and molecular functions were studied using the miRWalk and miRBase databases. Then the candidate miRNA was cloned into a lentiviral vector. Following, human dermal fibroblasts were cultured and treated with compounds forskolin, valproic acid, and CHIR99021. After 24 h, the lentivector harboring miRNA gene was transfected into the cells to initiate the transdifferentiation process. Finally, after a two-week treatment period, the efficiency of transdifferentiation was examined by inspecting the appearance of the cells and measuring the expression levels of cardiac genes and proteins using RT-qPCR and immunocytochemistry techniques. RESULTS Nine miRNAs were identified with higher expression in the heart. The miR-2392 was nominated as the candidate miRNA due to its function and specific expression in the heart. This miRNA has a direct connection with genes involved in cell growth and differentiation; e.g., MAPK and Wnt signaling pathways. According to in vitro results cardiac genes and proteins demonstrated an increase in expression in the fibroblasts that simultaneously received the three chemicals and miR-2392. CONCLUSION Considering the ability of miR-2392 to induce the expression of cardiac genes and proteins in fibroblast cells, it can induce fibroblasts to differentiate into cardiomyocyte-like cells. Therefore, miR-2392 could be further optimized for cardiomyocyte regeneration, tissue repair, and drug design studies.

Abstract
Recovery of valuable metals via leaching printed circuit boards (PCBs) has gained moment recently. This work studied the Microbial fuel cell (MFC) performances for recovery of Cu from a Cu2+ solution by examining key operating parameters. A dual-chamber MFC with 6 cm × 6 cm × 7 cm dimensions was constructed. Both anode and cathode electrodes were made of a carbon cloth sheet. The anodic and cathodic chambers were separated by a Nafion membrane. The highest Cu recovery efficiency was 99.7% after 240 h batch mode operation, yielding 102 mW/m2 MFC power density output using 1 g/L Cu2+ solution as the catholyte (initial pH 3) and an anolyte containing 1 g/L sodium acetate inoculated with a sludge from a wastewater treatment plant's anaerobic pond, with 2 cm distance between the electrodes made of polyacrylonitrile polymer. The highest open circuit voltage, current density (based on cross-section cathode area) and power density with an external load of 1 kΩ was 555 mV, 347 mA/m2 and 193 mW/m2, respectively. Additionally, recovery of Cu in the leachate of PCBs using sulfuric acid leaching after 48 h was performed and the highest Cu recovery was 50% in 48 h.

Abstract
Cartilage lesions are common conditions, affecting elderly and non-athletic populations. Despite recent advances, cartilage regeneration remains a major challenge today. The absence of an inflammatory response following damage and the inability of stem cells to penetrate into the healing site due to the absence of blood and lymph vessels are assumed to hinder joint repair. Stem cell-based regeneration and tissue engineering have opened new horizons for treatment. With advances in biological sciences, especially stem cell research, the function of various growth factors in the regulation of cell proliferation and differentiation has been established. Mesenchymal stem cells (MSCs) isolated from different tissues have been shown to increase into therapeutically relevant cell numbers and differentiate into mature chondrocytes. As MSCs can differentiate and become engrafted inside the host, they are considered suitable candidates for cartilage regeneration. Stem cells from human exfoliated deciduous teeth (SHED) provide a novel and non-invasive source of MSCs. Due to their simple isolation, chondrogenic differentiation potential, and minimal immunogenicity, they can be an interesting option for cartilage regeneration. Recent studies have reported that SHED-derived secretome contains biomolecules and compounds that efficiently promote regeneration in damaged tissues, including cartilage. Overall, this review highlighted the advances and challenges of cartilage regeneration using stem cell-based therapies by focusing on SHED.

Abstract
BACKGROUND Esophageal Squamous Cell Carcinoma (ESCC) is a highly aggressive tumor with increased metastatic potential. Recent evidence suggests that esophageal CSCs have a crucial role in tumor initiation, progression, and resistance to conventional anti-cancer therapies. The study aimed to develop mouse model to mimic the late steps of the metastasis process using a tail-vein injection of esophageal CSCs. METHODS AND RESULTS The sphere formation assay was used to enrich CSCs. For analysis of tumorigenicity, YM-1 adherent cells and enriched CSCs were injected subcutaneously into dorsal flank of nude mice. The expression of SLUG, E-cad, and CTHRC1 genes was examined by Real-Time qRT-PCR and immunohistochemistry (IHC) methods. To assess the metastatic potential of adherent YM-1 cells and their enriched CSCs, we injected the cells into the tail vein of nude mice. Our findings showed the up-regulation of SLUG and down-regulation of E-cad in the esophageal CSC-derived tumors (ECSCTs) compared to adherent cells-derived tumors. There was no statistically significant difference between CTHRC1 gene expressions in both groups of tumors. IHC staining confirmed the higher expression of SLUG protein in ECSCTs compared to adherent cell-derived tumors. Enriched CSCs were able to metastasize to the lungs and livers after three months, but, metastasis of adherent cells wasn't observed. CONCLUSION Our study showed esophageal CSCs injected through the tail-vein injection can migrate and metastasize to the lung and liver after three months. The developed metastatic mouse model can be a valuable and relevant model to investigate the molecular and cellular mechanisms of metastasis and develop successful targeted therapies against ESCC. The present study is one of the few studies that investigate the metastasis of esophageal cancer stem cells (ESCC type) through injection into the tail vein of nude mice.

Abstract
BACKGROUND SOX2OT is a novel cancer associated long non-coding RNA (LncRNA) with higher expression in variable tumor tissues, including esophageal squamous cell carcinoma (ESCC). It also plays an important function in embryonic neuronal development. Regarding its function in both stemness and carcinogenesis, here, we aimed to investigate its expression and function in tumorspheres of the esophagus using the RNAi method. MATERIAL & METHODS Two esophageal squamous cancer cells (ESCC): KYSE30 and YM1 cells were used for sphere enrichment. Cells were transfected with SOX2OT targeting and control siRNA. The size and the number of spheres were measured using light microscopy. Gene expression of the pluripotency genes was measured by qRT-PCR and docetaxel chemoresistance was assessed by MTS viability assay. RESULTS Our findings showed that ESCC tumorspheres overexpress SOX2OT gene along with other stemness genes (SOX2, OCT4A, and Nanog) compared to their original cancer cells. RNAi experiments indicated that SOX2OT knockdown can suppress the stemness-related gene expression, sphere formation ability (both size and number), and docetaxel resistance as three of the main cancer stem cell characteristics of tumorspheres. CONCLUSION Altogether our results showed the regulatory role of SOX2OT in pluripotency and stemness in ESCC tumorspheres. Our results suggest a potential application of SOX2OT inhibition in combination with docetaxel for ESCC inhibition in vitro.

Abstract
BACKGROUND AND AIMS Food processing changes the nature of foods, and it is growing globally due to its availability and affordability and its effects on the palatability of foods. Consumption of ultraprocessed foods (UPFs) may adversely affect weight gain. The purpose of the current study is to examine the association between UPFs consumption and adiposity among Iranian adults. METHODS AND RESULTS A cross-sectional study was conducted on 1459 Iranian adults (≥19 years). Dietary intakes were assessed using a validated 136-item food frequency questionnaire (FFQ), and foods were classified based on the NOVA system. Overweight, obesity, and abdominal obesity were defined as body mass index (BMI) ≥25 and < 30, ≥30, respectively, and waist circumference (WC) ≥91 for women and WC ≥ 89 for men. The odds of general and abdominal obesity across the quartiles of UPFs were assessed by binary logistic regression. UPFs consumption contributed to 20.17% of daily energy intake. After adjustment for potential confounders, UPFs consumption was not associated with general or abdominal obesity. However, in the fully adjusted model, men in the top quartile of UPFs were twice as likely to be overweight compared with those in the bottom quartile (OR = 2.06, 95% CI: 1.03, 4.10; P = 0.047). No association was found in women or stratified analysis by age. CONCLUSION The present findings suggest a sex-specific association between UPFs consumption and overweight. UPFs consumption might be associated with an increased risk of overweight in men, but no such association was found in women. Future cohort studies are required to confirm these results.

Abstract
Natural killer (NK) cells are innate lymphocytes that can kill tumor cells via different pathways, including the secretion of cytotoxic granules in immunological synapses and the binding of apoptosis-inducing ligands with cognate death receptors on tumor cells. These ligands are also soluble in NK cells conditioned medium (NK-CM). However, novel preclinical in vitro models are required for solid tumors such as colorectal cancer (CRC) to investigate apoptosis induction of activated NK-CM in a tissue-like structure. In the present study, we established a patient-derived CRC organoid culture system as a new tool for CRC research in the last decade. Tumor organoids were stained with hematoxylin and eosin (H&E) and compared with the original tumor taken from the patient. Goblet cell differentiation and mucus secretion were evaluated using periodic acid–Schiff and alcian blue histochemical staining. Moreover, tumor organoids were stained for CDX2 and Ki67 markers with immunohistochemistry (IHC) to investigate gastrointestinal origin and proliferation. Histopathological evaluations indicated tumor organoids represent patient tumor characteristics. Primary NK cells were isolated and characterized using CD56 marker expression and the lack of the CD3 marker. Flow cytometry results showed the purity of isolated CD3−and CD56 + NK cells about 93%. After further ex vivo expansion, IL-2-activated NK-CM was collected. Secretions of IFN-γ and TNF-α were measured to characterize activated NK-CM. Cytokines levels were significantly elevated in comparison to the control group. Soluble forms of apoptosis-inducing ligands, including TNF-related apoptosis-inducing ligand (TRAIL) and FasL, were detected by western blot assay. Colon cancer organoids were treated by IL-2-activated NK-CM. Apoptosis was assessed by Annexin V-FITC/PI staining and quantified by flow cytometry. In conclusion, despite the activated NK-CM containing apoptosis-inducing ligands, these ligands’ soluble forms failed to induce apoptosis in patient-derived colon cancer organoids. Nevertheless, we report a reliable in vitro assessment platform in a personalized setting.

Abstract
OBJECTIVES This study aimed to summarise the effect of community-based intervention programmes on the prevention of cardiovascular disease (CVD) by reducing cardiometabolic risk factors. STUDY DESIGN This was a systematic review and meta-analysis. METHODS A systematic search in the PubMed database and screening of reference lists aimed to identify community-based CVD prevention programmes from inception up to April 2020. The mean differences and standard deviations for CVD risk factors, including blood pressure, lipid profile, blood glucose and body weight indices, were extracted and pooled using a random effects model. RESULTS Screening of 11,889 titles/abstracts and full texts resulted in 48 studies being included in this review. The meta-analysis showed that community-based programmes have led to considerable decreases in systolic blood pressure (weighted mean difference [WMD] = -2.90 mm Hg, 95% confidence interval [95% CI]: -3.63, -2.16), diastolic blood pressure (WMD = -2.21 mm Hg, 95% CI: -3.12, -1.29), serum levels of low-density lipoprotein cholesterol (LDL-C; WMD = -8.88 mg/dl, 95% CI: -12.84, -4.92), triglycerides (WMD = -8.40 mg/dl, 95% CI: -12.10, -4.70), total cholesterol (WMD = -2.96 mg/dl, 95% CI: -3.10, -2.81) and fasting blood glucose (WMD = -2.06 mg/dl, 95% CI: -3.02, -1.10). A moderate decrease in body weight was also found with community-based CVD prevention programmes. However, community-based CVD prevention programmes were not associated with any significant changes in serum levels of high-density lipoprotein. CONCLUSIONS The present study indicates that community-based strategies have successfully led to an improvement in CVD risk factors, particularly by reducing blood pressure, serum levels of LDL-C and triglycerides, obesity indices and blood glucose. The impact of these programmes on CVD is modified by the type of intervention and by different cultural and physical environments.

Abstract
Background Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is currently the most important etiological agent of acute respiratory distress syndrome (ARDS) with millions of infections and deaths in the last 2 years worldwide. Several reasons and parameters are responsible for the difficult management of coronavirus disease-2019 (COVID-19) patients; the first is virus behavioral factors such as high transmission rate, and the different molecular and cellular mechanisms of pathogenesis remain a matter of controversy, which is another factor. Summary In the present review, we attempted to explain about features of SARS-COV-2, particularly focusing on the various aspects of pathogenesis and treatment strategies. Key Messages We note evidence for the understanding of the precise molecular and cellular mechanisms of SARS-CoV-2 pathogenesis, which can help design the appropriate drug or vaccine. Additionally, and importantly, we reported the updated issues associated with the history and development of treatment strategies such as, drugs, vaccines, and other medications that have been approved or under consideration in clinics and markets worldwide.

Abstract
Purpose: Esophageal squamous cell carcinoma (ESCC) is a highly aggressive cancer. The main cause of death in ESCC is related to relapse, metastasis, and resistance to cancer therapy. Recent studies have shown that a minor subset of cancer cells, known as cancer stem cells (CSCs), are responsible for tumor formation initiation and cancer progression. Understanding the genes associated with CSCs and metastasis can help in targeted cancer therapy. The aim of this study was to assess the expression of LAMB3 and TOP2A metastasis-associated genes in CSCs and adherent cells in the xenograft mouse model. Methods: Esophageal CSCs were enriched by the sphere formation method. The expression level of LAMB3 and TOP2A genes were evaluated in spheres and adherent cells in vitro by qRT-PCR. A xenograft mouse model was established to investigate the tumorigenesis and metastasis potential by subcutaneous and tail vein injection of CSCs and adherent YM-1 cells. Consequently, LAMB3 and TOP2A expression at the mRNA level was assessed in tumors. Immunohistochemistry was also used to evaluate the LAMB3 expression at the protein level in tumors. Results: CSCs-derived tumor was developed more quickly than the adherent cells-derived tumor. LAMB3 at mRNA and protein level was significantly down-regulated in sphere-derived tumor compared with adherent cells-derived tumor (p-value <0.05). TOP2A expression was almost similar in both sphere cells and adherent cells and there was no significant difference. Conclusion: we concluded that YM-1 spheres have CSCs characteristics in vitro with high capability of tumorigenicity in vivo. Our results were also shown that the LAMB3 expression was decreased in YM-1 spheres suggesting LAMB3 association with sphere formation.

Abstract
BACKGROUND Targeting Cancer Stem-Like Cells (CSLCs) can provide promising new therapeutic strategies to inhibit cancer progression, metastasis and recurrence. Salinomycin (Sal), an antibacterial ionophore, has been shown to inhibit CSCs specifically. Recently, it has been reported that Sal can destabilize TAZ, the hypo pathway transducer in CSLCs. OBJECTIVES Here, in the current study, we aimed to assess the differential toxicity of Sal in esophageal CSLCs and its relation to TAZ gene expression. METHODS The esophageal cancer cell line, KYSE-30, was used for the enrichment of CSLCs. The expression of TAZ was knocked down using specific siRNA transfection and then the cytotoxicity of Sal was measured using XTT assay. The qRT-PCR method was used for gene expression assessment and the sphere formation ability was monitored using light microscopy. RESULTS Our findings showed that esophageal CSLCs over-express stemness-associated genes, including SOX2, OCT4 as well as TAZ (~14 fold, P value=0.02) transcription coactivator. We found Sal can selectively inhibit KYSE-30 CSLCs viability and sphere formation ability; however, TAZ knockdown does not change its differential toxicity. CONCLUSION Overall, our results indicated that Sal can selectively decrease the viability of esophageal CSLCs in a TAZ-independent manner.

Abstract
Glioblastoma is a very invasive and prevalent brain tumor that affects 15 in 100,000 persons over the age of 70 years. Studies have shown that the expression of the WD repeat domain 81 (WDR81) gene, which is effective in vesicular transport and inhibition of autophagy, is increased in glioblastoma. The decreased autophagy was found to be related to the increased production of exosomes, which is a major factor in the pathogenesis of glioblastoma. The PI-3kinase complex is a pre-autophagic complex that is highly active in the absence of WDR81. The WDR81 gene, as a negative regulator of PI3K activity, prevents autophagy and increases exosome secretion by preventing the formation of the class III PI3K complex. Therefore, targeted reduction of exosomes can be considered an effective strategy for reducing the pathogenesis of glioblastoma. This study aimed to assess the effect of WDR81 gene silencing with siRNA on exosome levels in a U87-MG cell line. Culturing of U87-MG cells was carried out in Dulbecco's modified Eagle medium (DMEM) containing 5% FBS and 1% penicillin/streptomycin. Thereafter, silencing of WDR81 was performed using WDR81 siRNA, whose gene expression level was determined via real-time qRT-PCR. Cell viability was evaluated using the MTT assay. The exosomes were extracted from a cell culture using the Exocib kit. The size accuracy of the exosomes was confirmed by dynamic light scattering (DLS). Finally, the protein content and RNA of the exosomes were assessed. WDR81 gene expression of siRNA-transfected cells was decreased to 82% after 24 h compared to the non-transfected control cells. The analysis of the exosomes showed that the concentration of exosomes and their RNA and protein content in the siRNA-transfected cells decreased significantly compared to the non-transfected control cells. No considerable difference was observed in cell viability after transfection with either WDR81-specific siRNAs or scrambled control siRNAs. Our findings showed that silencing the WDR81 gene could reduce the level of exosomes in human U87-MG glioblastoma cells. Therefore, the reduced exosome content may be suggested as a new gene therapy strategy for targeted therapy of glioblastoma by increasing autophagy via activation of PI3KIII. However, more studies are needed in this regard.

Abstract
Cancer stem cells are a rare population in tumors with high metastatic potential and resistance to treatment. Recent strategies in cancer treatment have focused on targeting important signaling pathways that have an important role in maintaining CSC populations. TAZ (transcriptional co-activator with PDZ-binding motif) is a key downstream of the Hippo pathway which plays a fundamental role in the survival of CSCs from different origins, however, no data on the role of TAZ in esophageal cancer are available. Our findings showed that esophageal CSCs enriched from the YM-1 cell line have stemness properties. We found that TAZ was strongly expressed in esophageal CSCs and knockdown of TAZ in esophageal CSCs results in reduced colony formation and cell migration. Moreover, this data indicated that TAZ knockdown reduces the expression of SOX-2, OCT-4, and Nanong in esophageal CSCs. Taken together, the results of the current study suggested that TAZ has a crucial role in the biology of esophageal CSCs.

Abstract
BACKGROUND Self-harm-related death is one of the most unfortunate, tragic, and regrettable types of death owing to injuries with a variety of socio-economic and cultural causes. The study aimed to determine the trend in the mortality of self-harm by sex and age at national and provincial levels in Iran over a period of 26 years. METHODS The Iran Death Registration System (DRS), cemetery databanks in Tehran and Esfahan, and the national population and housing censuses of Iran were used for this study. Using a growth model, the population was estimated in the age groups. Incompleteness, misalignment, and misclassification in the DRS were all considered and addressed accordingly. We used a spatio-temporal and Gaussian process regression model to estimate mortality rates in children and adults. RESULTS Over the study period, 67,670 deaths were estimated owing to self-harm across the country. The overall age-standardized mortality rate decreased from 4.32 per 100,000 (95% unit interface (UI): 3.25-5.75) to 2.78 (2.15-3.59) per 100,000 between 1990 and 2015, a reduction of approximately 35.65%. The M/F ratio was 2.03:1 with an annual percent change of -2.38% and -1.37% for women and men, respectively. The annual self-harm mortality rate was higher among individuals aged 15-24 years, as well as it was more in men during the study period. CONCLUSION Mortality from self-harm has declined over the study period in Iran. Higher rates in men and in population aged 15-24 years, with considerable variation by province, were the distinguishing features of self-harm. Iran needs to improve monitoring through a comprehensive multisectoral strategy; and most importantly, provide timely, effective and low-cost preventive interventions.

Abstract
The aim of this study was to estimate the basic reproduction number (R0) of COVID-19 in the early stage of the epidemic and predict the expected number of new cases in Shahroud in Northeastern Iran. The R0 of COVID-19 was estimated using the serial interval distribution and the number of incidence cases. The 30-day probable incidence and cumulative incidence were predicted using the assumption that daily incidence follows a Poisson distribution determined by daily infectiousness. Data analysis was done using 'earlyR' and 'projections' packages in R software. The maximum-likelihood value of R0 was 2.7 (95% confidence interval (CI): 2.1-3.4) for the COVID-19 epidemic in the early 14 days and decreased to 1.13 (95% CI 1.03-1.25) by the end of day 42. The expected average number of new cases in Shahroud was 9.0 ± 3.8 cases/day, which means an estimated total of 271 (95% CI: 178-383) new cases for the period between 02 April to 03 May 2020. By day 67 (27 April), the effective reproduction number (Rt), which had a descending trend and was around 1, reduced to 0.70. Based on the Rt for the last 21 days (days 46-67 of the epidemic), the prediction for 27 April to 26 May is a mean daily cases of 2.9 ± 2.0 with 87 (48-136) new cases. In order to maintain R below 1, we strongly recommend enforcing and continuing the current preventive measures, restricting travel and providing screening tests for a larger proportion of the population.

Abstract
Recently, studies have shown that Fucosylation plays an important role in the invasion and metastatic process of CSLCs. Understanding the expression pattern of fucosyltransferase (FUT) genes may help to suggest better-targeted therapy strategies for esophageal squamous cell carcinoma (ESCC). The study aimed to address the expression pattern of FUT gene variants in esophageal CSLCs and parental adherent cells. Sphere formation method was used to enrich CSLCs. Expression of FUT genes was examined in tumor sphere and parental adherent cells using the RT-PCR method and then relative expression of detected variants was performed by the Real-Time PCR method in both groups. The detected FUTs, also, were assessed in fresh ESCC tumors and the matched healthy controls. Analysis of The cell surface carbohydrate Lewis x (LeX, CD15) was performed by flow cytometry. Molecular analysis showed that the expression of FUT 3, 8 and POFUT1, 2 genes in tumorsphere were significantly higher than parental adherent cells. Analysis of fresh ESCC tumor tissues and the matched healthy controls showed that FUT8 and POFUT1, 2 genes in contrast to FUT 3 have higher expression in tumor tissues than controls. Flow cytometric analyses revealed that tumorsphere and their parent cells do not differ significantly in Lewis x surface marker. The present study showed that FUT 3, 8 and POFUT1, 2 genes upregulated in esophageal CSLCs in comparison to adherent cells. Understanding the expression pattern of FUT gene variants may help to suggest better-targeted therapy strategies for ESCC.

Abstract
BACKGROUND chemotherapy drugs are the common therapy for cancer cells with side effects. Recent studies reported that natural products may contribute to decreasing the side effects of chemotherapy drugs. Here, we aimed to investigate the effects of orange peel extract (OPE) and its main compound; naringin (NR) to protect the side effects of doxorubicin (Dox) in esophageal cancer stem cells (CSCs) derived tumors in vivo. METHODS for this purpose, Esophageal cancer cell (YM1) derived spheres were treated in vitro with OPE, NR, Dox, Dox in combination with OPE or NR. The cell viability was assessed by XTT and the apoptosis was measured using Annexin/7-AAD and the cell cycle was also quantified by using PI staining method. The pluripotency related genes expression was carried out using qRT-PCR The protective effects of OPE and NR were evaluated by body weight evaluation and oxidative stress factors: malondialdehyde (MDA), total antioxidant capacity (TAC) and superoxide dismutase (SOD) measurement in xenograft mice tumor model injected with Dox. RESULTS ESCC CSCs overexpress SOX2 and OCT4 pluripotency genes. OPE or NR can protect the cellular toxicity of Dox in vitro mainly by decreasing cellular apoptosis of ESCC CSCs however S-phase cell cycle arrest has not been affected significantly. In vivo experiments revealed that the use of Dox simultaneously with OPE or NR not only can reduce the tumor size but also the body weight of the treated nude mice were maintained in comparison to Dox alone. In contrast to Dox alone, Dox in combination with OPE or NR showed less systemic toxicity and decreased oxidative stress fraction circulation, however, OPE seemed as more protective. CONCLUSION The results suggest that these natural compounds can be used as adjuvant therapy to lower systemic toxicity of chemotherapeutic agents like DOX in ESCC cancer stem cells treatment.

Abstract
Dysregulation of helper T (Th) cell subsets has been contributed to the initiation and propagation of esophageal squamous cell carcinoma (ESCC). Different microRNAs (miRNAs) have been reported to control the development and functions of tumor-associated immune cells in ESCC. Here, we aimed to assess the IL-10, TGF-β, IFN-γ, and IL-17a-producing CD3+CD8- T cells in association whit miR-21, miR-29b, miR-106a, and miR-155 expression in ESCC patients. A total of 34 ESCC patients including 12 newly diagnosed (ND) and 22 under-treatment (UT) cases and also 34 age-matched healthy donors were enrolled. Flow cytometric characterization of stimulated T cells was performed by staining of the cells with fluorescent conjugated specific anti-human CD3 and CD8 cell surface markers as well as IL-17a, IFN-γ, IL-10, and TGF-β intracytoplasmic cytokines. Circulating RNA was extracted from the plasma, and qRT-PCR was used to evaluate the expression of microRNAs. TGF-β plasma levels were also assessed by ELISA. Results showed that the frequency of Th cells was significantly reduced in patients. A significant increase in Treg as well as Th17 cells population in both patient subgroups was observed. ND patients showed elevated level of Th1 cells and IL-10. However the mean expression of IFN-γ was significantly decreased in Th cells. We also detected higher level of miR-21 in the ESCC patients which was significantly correlated with different subsets of Th cells. Our findings revealed that immune response related to the Th cells is highly impaired in ESCC patients. Association between miR-21 and Th subsets could be correlated with the impairment of anti-tumor immunity and ESCC pathogenesis, which could be potentially used as an important target for immunotherapeutic approaches.

Abstract
BACKGROUND
The association between X-ray repair cross-complementing group 1 (XRCC1) Arg399Gln
gene polymorphism and hepatocellular carcinoma (HCC) has been investigated in several populations.
However, the findings are controversial. The aim of this study was to address the association
between XRCC1 Arg399Gln polymorphism and HCC in an Iranian population.
METHODS
We have evaluated the association between XRCC1 Arg399Gln gene polymorphism and HCC
in 151 Iranian individuals (50 patients with HCC and 101 healthy matched controls) using polymerase
chain reaction-restriction fragment length polymorphisms (PCR-RFLP) method.
RESULTS
Significant association was found for the XRCC1 A allele and HCC [OR = 1.93, 95% CI (1.16
- 3.25), P = 0.0099]. Also, genotype analysis by SNPStats online software showed a significant
association between XRCC1 gene polymorphisms and HCC under co-dominant, dominant, and
recessive genetic models.
CONCLUSION
Our study provides evidence that the XRCC1 Arg399Gln polymorphism may be associated
with the risk of HCC development in Iranian population.

Abstract
AIM The aim of this study was to address the association of the EGF gene +61A/G polymorphisms and HCC susceptibility in an Iranian population. BACKGROUND The association of epidermal growth factor (EGF) gene +61A/G polymorphism (rs4444903) and hepatocellular carcinoma (HCC) has been investigated in several populations. However, the findings are controversial. METHODS A total of 40 unrelated HCC patients and 106 healthy individuals were enrolled in this study. Genomic DNA of HCC patients was extracted from formalin-fixed, paraffin-embedded samples using CinnaPure DNA kit according to manufacturer's instructions. Genomic DNA of healthy individuals, also, was extracted from peripheral blood cells using the boiling method. The rs4444903 (A/G) polymorphism was genotyped using the polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) method. RESULTS Significant association was found for the EGF +61A allele and HCC risk [OR = 1.72, 95% CI (1.02 - 2.90), P value = 0.04]. Also, significant association was observed for the EGF +61A/G genotypes and HCC risk under codominant and dominant models by SNPStats software analysis. CONCLUSION Our findings suggest that the EGF gene +61A/G polymorphism (rs4444903) might be a risk factor for susceptibility to HCC in Iranian population. However, further studies using more samples are needed.

Abstract
OBJECTIVE The potentiality to switch between yeast and hyphal morphologies plays an important role in the virulence of Candida albicans (C. albicans). The objective of the present study was to evaluate the chemical composition, antifungal activity and influence of propolis upon germ tube formation of C. albicans clinical isolates. METHODS The major compounds of propolis ethanolic extract (PEE) was revealed by gas chromatography-mass spectrometry (GC/MS) analysis. Broth microdilution method was used for determination of minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) of this extract. C. albicans isolates were exposed to sub-MIC concentrations of propolis and germ tube reduction percent (GRP) and morphological transition from yeast to filamentous form were monitored microscopically. RESULTS Phenolic compounds, aromatic acids, aliphatic acids, sugars and polycyclic aromatic hydrocarbons were the major compound classes in PEE. Mean of MIC and MFC values of PEE against C. albicans isolates were 360.6μg·mL-1 and 1250.1μg·mL-1, respectively. The increase in concentration led to a significant reduction in germ tube formation, so mean of GRP was 36.7±11.1 and 22±10.1 at concentration of ½ MIC and ¼ MIC of PEE, respectively. CONCLUSIONS In conclusion, the present study indicated that PEE has interesting potential as a therapeutic agent that targets germ tube formation by C. albicans as a critical virulence factor.

Abstract
The CC chemokine receptor 5 (CCR5) delta 32 allele results in a nonfunctional form of the chemokine receptor and has been implicated in a variety of immune-mediated diseases. CCR5Δ32 may also predispose one to chronic liver disease or be linked with resistance to HBV infection. This study was undertaken to investigate any association between CCR5 polymorphism with resistance to hepatitis B or susceptibility to HBV infection. A total of 812 Iranian individuals were enrolled into two groups: HBV infected cases (n=357), who were HBsAg-positive, and healthy controls (n=455). We assessed polymorphisms in the CCR5 gene using specific CCR5 oligonucleotide primers surrounding the breakpoint deletion. Genotype distributions of the HBV infected cases and healthy controls were determined and compared. The CCR5/CCR5 (WW) and CCR5/CCR5Δ32 (W/D) genotypes were found in (98%) and (2%) of HBV infected cases, respectively. The CCR5 Δ32/Δ32genotype was not found in HBV infected cases. Genotype distributions of CCR5 in healthy controls were W/W genotype in (87.3%), W/D genotype in (11.2%) and D/D genotype in (1.5%). Heterozygosity for CCR5/CCR5Δ32 (W/D) in healthy controls was greater than in HBV infected cases (11.2% vs 2%, p < 0.001). W/D and D/D genotypes were more prominent in healthy controls than in HBV infected cases. This study provides evidence that the CCR5Δ32 polymorphism may have a protective effect in resistance to HBV infection at least in the Iranian population.

Abstract
INTRODUCTION Diabetes mellitus is an important public health challenge worldwide. The prevalence of type 2 diabetes varies across countries. The aim of this study is to estimate the prevalence of type 2 diabetes and to determine related factors including socioeconomic factors in a large random sample of Tehran population in 2011. METHODS In this cross-sectional study, 91,814 individuals aged over 20 years were selected randomly based on a multistage, cluster sampling. All participants were interviewed by trained personnel using standard questionnaires. Prevalence and Townsend deprivation indexes were calculated. Principal component analysis (PCA) was used to construct wealth index. Logistic regression model was used in multivariate analysis. RESULTS The estimated prevalence of self-reported diabetes was 4.98 % overall, 4.76 %in men and 5.19 % in women (P < 0.003). In multivariate analysis, age, marital status (married and divorced/widow) and BMI were positively associated with the prevalence of self-reported diabetes. Of the socioeconomic variables, educational level and wealth status were negatively and Townsend Index was positively associated with diabetes. CONCLUSION Our study findings highlight low reported prevalence of diabetes among adults in Tehran. Subjects with low socioeconomic status (SES) had a higher prevalence of type 2 diabetes. Weight gain and obesity were the most important risk factors associated with type 2 diabetes. Wealth index and educational level were better socioeconomic indicators for presenting the inequality in diabetes prevalence in relation to Townsend deprivation index.

Abstract
BACKGROUND Lung cancer is one of the most common causes of death that is rising in many countries including Iran. This study aimed to determine the impact of factors on survival of lung cancer patients at a referral center of lung diseases in Tehran, Iran. MATERIALS AND METHODS A retrospective study was conducted on adult lung cancer cases admitted to a referral center for lung diseases from 2011 to 2015. Multivariate analysis was performed to determine the risk factors for all-cause mortality. RESULTS Of a total 933 patients with lung cancer, 53.4% died, 49.3% of them at the hospital. Overall median follow-up time was 7 months. The most common histological type of cancer was adenocarcinoma with a 13 month median survival time. Age ≥55 and smoking remained significant for all-cause mortality on Cox analysis, whereas gender was not. CONCLUSIONS The survival of lung cancer patients is poor and the patients with history of smoking and age ≥55 are at increased risk of death. Having a large hospital-based registry provides a good measurement of prognostic statistics for lung cancer. Further investigations are necessary to establish reasons for mortality.

Abstract
A total of 72 laying hens were used to investigate the effect of probiotic and lactose on body weight loss, tibia ash, antibody production against sheep red blood cell (SRBC), heterophile-to-lymphocyte (H/L) ratio and gut microbiota in a common moulting method for 14 d. Hens were randomly allocated to 6 experimental groups consisting of (i) full feed (FF), (ii) feed withdrawal (FW), (iii) FW with calcium (Ca), (iv) FW with Ca and offering 7 g/lit lactose in drinking water (CaL), (v) FW with Ca and offering 1 g/lit probiotic in drinking water (CaP), and (vi) FW with Ca and offering a mixture of lactose and probiotic in drinking water (CaLP). The results showed body weight loss in all FW groups were more than 25% that was significantly higher than FF group (p < 0.05). The relative organ weights of hens in FW groups were lower than FF group; especially, it was significant for liver and ovary (p < 0.05). No significant difference was observed between all groups for tibia ash. The highest H/L ratio was related to FW group and offering Ca and lactose numerically and probiotic alone significantly resulted in decrease of this ratio (p < 0.05). The results also showed no significant difference for antibody production against SRBC among experimental groups. The highest coliform bacteria numeration observed in FW group and lactose could significantly reduce this population (p < 0.05). Lactic acid bacteria (LAB) numeration demonstrated a significant difference among treatments, so that FF hens had higher LAB than others (p < 0.05). In addition, FW moulted hens had significantly lower LAB compared to other moulted hens (p < 0.05), except for Ca group. In conclusion, probiotic and lactose was effective in maintaining caecal microbiota balance and improving immunity in hens exposed to moulting.

Abstract
Computational simulations have the potential to aid understanding of cardiovascular hemodynamics under physiological conditions, including exercise. Therefore, blood hemodynamic parameters during different heart rates, rest and exercise have been investigated, using a numerical method. A model was developed for a healthy subject. Using geometrical data acquired by echo-Doppler, a two-dimensional model of the chamber of aortic sinus valsalva and aortic root was created. Systolic ventricular and aortic pressures were applied as boundary conditions computationally. These pressures were the initial physical conditions applied to the model to predict valve deformation and changes in hemodynamics. They were the clinically measured brachial pressures plus differences between brachial, central and left ventricular pressures. Echocardiographic imaging was also used to acquire different ejection times, necessary for pressure waveform equations of blood flow during exercise. A fluid-structure interaction simulation was performed, using an arbitrary Lagrangian-Eulerian mesh. During exercise, peak vorticity increased by 14.8%, peak shear rate by 15.8%, peak cell Reynolds number by 20%, peak leaflet tip velocity increased by 47% and the blood velocity increased by 3% through the leaflets, whereas full opening time decreased by 11%. Our results show that numerical methods can be combined with clinical measurements to provide good estimates of patient-specific hemodynamics at different heart rates.

Abstract
The Islamic Republic of Iran, in her 20 year vision by the year 2025, is a developed country with the first economic, scientific and technological status in the region, with revolutionary and Islamic identity, inspiring Islamic world, as well as effective and constructive interaction in international relations. Enjoying health, welfare, food security, social security, equal opportunities, fair income distribution, strong family structure; to be away from poverty, corruption, and discrimination; and benefiting desirable living environment are also considered out of characteristics of Iranian society in that year. Strategic leadership towards perceived vision in each setting requires restrictive, complete and timely information. According to constitution of National Institute for Health Researches, law of the Fifth Development Plan of the country and characteristics of health policy making, necessity of designing a Health Observatory System (HOS) was felt. Some Principles for designing such system were formulated by taking following steps: reviewing experience in other countries, having local history of the HOS in mind, superior documents, analysis of current production and management of health information, taking the possibilities to run a HOS into account. Based on these principles, the protocol of HOS was outlined in 3 different stages of opinion poll of informed experts responsible for production on management of information, by using questionnaires and Focus Group Discussions. The protocol includes executive regulations, the list of health indicators, vocabulary and a calendar for periodic studies of the community health situation.
