Abstract
Bacterial blight and leaf spot of geraniums is a destructive disease of cultivated Pelargonium species around the world. During 2020-2021, surveys were conducted in seven geranium-growing provinces of Iran to monitor the status of bacterial blight and leaf spot disease. The disease was observed in six surveyed provinces varying in the extent of occurrence and severity. Twenty-two Gram-negative pale-yellow bacterial strains resembling members of Xanthomonas were isolated from symptomatic leaves and stems. Pathogenicity and host range assays showed that the bacterial strains were pathogenic on Pelargonium grandiflorum, P. graveolens, P. peltatum, and P. zonale. All strains were positive for PCR test using the primer pair XcpM1/XcpM2 which is specific for Xanthomonas hortorum pv. pelargonii. Phylogenetic analysis using the sequences of gyrB and lepA genes showed that the 22 strains clustered in a clade among the sequences of X. hortorum pv. pelargonii strains retrieved from the GenBank, while distinct from the other pathovars of X. hortorum. BOX-PCR-based fingerprinting using BOX-A1R primer revealed that the strains isolated in this study were grouped into two clusters while no distinct correlation was observed between the host/area of isolation and BOX-PCR fingerprinting. None of the strains obtained in this study nor reference strain of the pathogen did produce bacteriocin against each other. Results obtained in this study shed light on the geographic distribution, taxonomic status and host range of the bacterial blight and leaf spot pathogen of geraniums in Iran, paving the path of further research on disease management.

Abstract
Overexpression of HER2 in endometrial cancer is associated with poor prognosis, aggressive disease, and resistance to standard therapies. Recent studies have shown that HER2-targeted therapies, such as trastuzumab, can be effective in treating HER2-positive endometrial cancer in combination with chemotherapy. Currently, the management of advanced-stage HER2-positive uterine serous carcinoma (USC) consists of adjuvant platinum-based chemotherapy with concurrent trastuzumab followed by trastuzumab maintenance therapy until disease recurrence or prohibitive toxicity. In the setting of persistent pelvic disease following systemic therapy, consolidation with tumor-directed radiation therapy also offers an opportunity to eradicate residual disease. With the emergence of molecular tumor classifications and systemic therapies (chemotherapy, immunotherapy, and target therapies), the landscape of adjuvant multi-modality therapy is ever changing and increasingly individualized. Currently, there is no prospective evidence to guide pelvic radiotherapy with concurrent trastuzumab in endometrial cancer, and as a result, no reported toxicity in endometrial cancer patients. In this case report, we present two patients with HER2-positive USC who received multi-agent chemotherapy with trastuzumab followed by pelvic radiation therapy and concurrent trastuzumab. Both patients tolerated this multimodal treatment without significant or persistent moderate or severe adverse events. These two cases provide insight into the safety and feasibility of administering radiation therapy with trastuzumab in endometrial cancer in the maintenance phase. Our report suggests that trastuzumab-based therapy may be a promising treatment option for HER2-positive endometrial cancer patients who receive concurrent or adjuvant chemotherapy and radiation therapy.

Abstract
BACKGROUND Systemic lupus erythematosus (SLE) is an autoimmune disease in which the immune system abnormally reacts against cells and tissues leading to inflammation. Epigenetic alterations, including DNA methylation and histone modification, have critical effects on autoimmune disease and SLE pathogenesis via dysregulation of critical genes. AIMS The purpose of this study was to evaluate the epigenetic-related gene expression of DNA methyltransferase (DNMT) and histone deacetylase 1 (HDAC1) in Iranian patients with SLE. METHODS This matched case-control study included 16 people with SLE and 16 healthy people who were referred to the Rafsanjani rheumatology clinic, in southeast Iran. The expression of DNMT and HDAC1 genes was measured through a real-time PCR assay of blood samples. RESULTS DNMT gene expression did not differ significantly between SLE and healthy groups (P=0.21). In contrast, HDAC1 gene expression was enhanced in the SLE group, but this enhancement failed to reach statistical significance (P=0.94). CONCLUSION The results of this study suggest that overexpression of HDAC1 could serve as a diagnostic for SLE disease. Additional studies with larger sample sizes are required to confirm our findings. Evaluation of other genes related to SLE disease is essential and may help to make an accurate diagnosis of the disease.

Methods:
In this experimental study, HCT116 cells were treated with different treatments of encapsulation of ATX in β-LG, encapsulation 5-FU in β-LG, co-encapsulation of ATX and 5-FU in β-LG, free ATX, free 5-FU, free ATX and free 5-FU, or β-LG nanocapsules without drugs for 24, 48 and 72 hours. There is a control group in which HCT116 cells were not treated with any drug. Then, 50% inhibitory concentration (IC50) and cell viability were determined using an MTT assay. The antioxidant enzyme activity of SOD, CAT, and GPX was measured by a colorimetric method in HCT116 cells.

The antioxidant enzyme activity of SOD, CAT and GPX was measured by colorimetric methods in HCT116 cells.
Results:
Different treatments reduced the cell viability and increased apoptotic cells in a time-dependent manner, which was significant for beta-lactoglobulin nanocapsules treatment (P<0.05). It means receiving more 5-FU or ATX in the encapsulated form by HCT116 cells. The antioxidant enzyme activity of SOD, CAT, and GPX in HCT116 cells treated with beta-lactoglobulin nanocapsule treatment significantly increased compared to the control group (P<0.001). Moreover, the antioxidant activity of these enzymes in different treatments containing ATX (free or encapsulation) was significantly higher than in other treatments (P<0.05). The most increase in the activity of antioxidant enzymes is recorded in the treatment of nanocapsules containing ATX and 5-FU simultaneously.
result:
Different treatments reduced the cell viability and increased apoptotic cells in a time-dependent manner, which this reduction was significant for beta-lactoglobulin nanocapsules treatments (P&amp;amp;amp;lt;0.05). It means receiving more 5-FU or ATX in encapsulated form by HCT116 cells. The antioxidant enzymes activity of SOD, CAT and GPX in HCT116 cells treated with beta-lactoglobulin nanocapsules treatments significantly increased compared to the control group (P&amp;amp;amp;lt;0.001). Also, the antioxidant activity of these enzymes in different treatments containing ATX (free or encapsulation) was significantly higher than other treatments (P&amp;amp;amp;lt;0.05). The most increase in the activity of antioxidant enzymes is recorded in the treatment of nanocapsules containing ATX and 5-FU simultaneously.
Conclusion:
Increased activity of antioxidant enzymes in addition to the induction of apoptosis in colorectal cancer cells by various treatments of beta-lactoglobulin nanocapsules indicates more effective drug administration in encapsulated form as well as synergistic thera[peutic effects of ATX and 5-FU. Moreover, the main increase in antioxidant enzyme activity may be related to ATX.

Abstract
Xanthomonas arboricola comprises a number of economically important fruit tree pathogens classified within different pathovars. Dozens of nonpathogenic and taxonomically unvalidated strains are also designated as X. arboricola, leading to a complicated taxonomic status in the species. In this study, we have evaluated the whole-genome resources of all available Xanthomonas spp. strains designated as X. arboricola in the public databases to refine the members of the species based on DNA similarity indexes and core genome-based phylogeny. Our results show that, of the nine validly described pathovars within X. arboricola, pathotype strains of seven pathovars are taxonomically genuine, belonging to the core clade of the species regardless of their pathogenicity on the host of isolation (thus the validity of pathovar status). However, strains of X. arboricola pv. guizotiae and X. arboricola pv. populi do not belong to X. arboricola because of the low DNA similarities between the type strain of the species and the pathotype strains of these two pathovars. Thus, we propose to elevate the two pathovars to the rank of a species as X. guizotiae sp. nov. with the type strain CFBP 7408T and X. populina sp. nov. with the type strain CFBP 3123T. In addition, other mislabeled strains of X. arboricola were scattered within Xanthomonas spp. that belong to previously described species or represent novel species that await formal description.

Abstract
The genus
Xanthomonas
contains a set of diverse bacterial strains, most of which are known for their pathogenicity on annual crops and fruit trees causing economically important plant diseases. Recently, five
Xanthomonas
strains were isolated from
Agrobacterium
-induced crown gall tissues of amaranth (Amaranthus sp.) and weeping fig (Ficus benjamina) plants in Iran. Phenotypic characteristics (i.e. biochemical tests and pathogenicity features) and whole genome sequence-based core-genome phylogeny followed by average nucleotide identity and digital DNA–DNA hybridization calculations suggested that these gall-associated strains belong to two new species within the genus
Xanthomonas
. In this study, we provide a formal species description for these new species where Xanthomonas bonasiae sp. nov. is proposed for the strains isolated from weeping fig with FX4T (=CFBP 8703T=DSM 112530T) as type strain. The name Xanthomonas youngii sp. nov. is proposed for the strains isolated from amaranth with AmX2T (=CFBP 8902T=DSM 112529T) as type strain.

Abstract
Previous multiple-choice food-based food frequency questionnaires (FFQs) were not validated against weighed dietary records (WDRs) in Iran. This study investigated the validity and reproducibility of a multiple-choice semiquantitative food frequency questionnaire (SQ-FFQ) in adults living in central Iran. Patients with diabetes and their spouses were asked to complete 3 SQ-FFQs by interview, and nine 3-day WDRs, over 9 months. They provided 2 blood samples to assess serum calcium, magnesium, zinc, and vitamin C levels. The Pearson and intraclass correlation coefficients were calculated to assess reproducibility and validity. The degree of misclassification was explored using a contingency table of quartiles which compare the information between third FFQ and WDRs. The method of triads was incorporated to assess validity coefficients between estimated intakes using third FFQ, WDRs, and biochemical markers and assumed true intakes. A total of 180 participants aged 48.9 ± 8.4 years completed the study. Compared to WDRs, FFQs overestimated all nutrient intakes except for iron. The median intraclass correlation between FFQs was 0.56. The median de-attenuated, age, sex, and education adjusted partial correlation coefficients for validity were 0.17 and 0.26 for FFQ1-WDRs and FFQ3-WDRs, respectively. The FFQ3 validity coefficients for vitamin C, calcium, magnesium, and zinc were 0.13, 0.62, 0.89, and 0.66, respectively, using the triads method. The median exact agreement and complete disagreement between FFQ3 and WDRs were 33% and 6%, respectively. The SQ-FFQ seems to be an acceptable tool to assess the long-term dietary intake for future large-scale studies in this population.

Abstract
Crown gall disease caused by diverse Agrobacterium species is one of the main biotic constraints in the ornamental plants industry in Iran (Mafakheri et al. 2017). In August 2019, Japanese spindle (Euonymus japonicus var. Green Rocket) plants showing crown gall symptoms were observed in a commercial greenhouse in Tehran, Iran. Infected plants were characterized by a visible overgrowth on their stems and crown. Bacterial isolation from the gall tissues was performed on nutrient agar (NA) and 1A media as described by Moore et al. (2001). The six resulted bacterial strains (A.E1 to A.E6) were evaluated using PCR primer pair F8360/F8361 amplifying a 453 bp DNA fragment in recA gene and confirmed as Agrobacterium sp. (Shams et al. 2013). Pathogenicity of the strains was evaluated in two independent assays on Japanese spindle plantlets as well as 10-15 day old tomato (Solanum lycopersicum cv. Sunseed 6189) and sunflower (Helianthus annuus cv. Armavirski) plants in greenhouse conditions using the needle prick method as described previously (Mafakheri et al. 2019). The reference strain A. radiobacter ICMP 5856 and sterile distilled water were used as positive and negative controls, respectively. Crown gall symptoms appeared 20-25 days post inoculation on the Japanese spindle plantlets as well as tomato and sunflower plants inoculated with the strains isolated in this study, while the negative control plants remained asymptomatic. Koch's postulates were accomplished by re-isolating on NA medium and PCR-based identification of the inoculated strains from the symptomatic plants. The representative strain A.E1 was subjected to multilocus sequence analysis (MLSA) using the sequences of four housekeeping genes (i.e. atpD, gyrB, recA, and rpoB) as described previously (Mafakheri et al. 2019). MLSA results revealed that the strain A.E1 is phylogenetically closely related to A. rosae. The sequences were deposited into GenBank under the accession numbers MT007962 to MT007965 for atpD, gyrB, recA, and rpoB, respectively. Further, the strain A.E1 was subjected to whole genome sequencing using Illumina HiSeq X platform. DNA extraction was performed using NucleoSpin Microbial DNA kit (Macherey-Nagel, Germany), DNA libraries were obtained with Nextera XT DNA Library Prep Kit (Illumina, USA), and de novo sequence assembly was performed using SPAdes genome assembler. The resulting whole genome sequence was deposited into the GenBank database under the accession number JAFJZW000000000. Average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values were calculated among all the type strains of Agrobacterium species/genomospecies using standard criteria as detailed previously (Osdaghi et al. 2020; Chen et al. 2021). The strain A.E1 had 97% ANI and 72% dDDH values with A. rosae strain NCPPB 1650, suggesting that the bacterial strains isolated from Japanese spindle in Iran belong to A. rosae. This is the first report of A. rosae causing crown gall disease on Japanese spindle in Iran. The new crown gall disease could negatively affect the ornamental shrub production industry in central Iran unless strict sanitary measures are taken into the account in the nurseries in these areas. Further nationwide surveys and samplings are warranted to elucidate the economic impact of the pathogen on ornamental plant industry in the country.

Abstract
BACKGROUND This study aimed to compare the effects of sesame (SO), canola (CO), and sesame-canola (SCO: a blend) oils on glycaemic control markers and liver function enzymes in adults with type 2 diabetes. METHODS In this randomized, triple-blind, three-way, cross-over clinical trial, participants replaced their usual oil with the intervention oils for 9 weeks. Serum fasting blood sugar, fasting serum insulin (FSI), insulin resistance (HOMA2-IR), beta-cell function (HOMA2-%B), insulin sensitivity (HOMA2-%S), quantitative insulin sensitivity check index (QUICKI), as well as serum liver function enzymes were measured at baseline and end of intervention periods. RESULTS Ninety-two participants completed all treatment periods. After adjusting for confounders, all treatment oils resulted in significant improvements in FSI and HOMA2-%S (p < 0.05). SO and SCO led to favourable changes in HOMA2-IR and QUICKI (p < 0.05). Following CO and SCO, there was a significant decrease in HOMA2-%B (p < 0.05). The sex-stratified analysis revealed that FSI and HOMA2-IR were decreased after SO compared to CO in males (p = 0.024). Serum gamma-glutamyltransferase (GGT) was significantly lower following SO compared to CO in females (p = 0.02), however, the difference in change values was not significant (p = 0.058). CONCLUSIONS SO consumption appears to improve glycaemic control markers in males and serum GGT in females compared with CO in patients with type 2 diabetes (registration code: IRCT2016091312571N6).

Abstract
Objective(s): Soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) complex proteins are involved in membrane trafficking. The expression of isoforms of SNAP-23, syntaxin-4, and VAMP-2 is significantly done in skeletal muscles; they control GLUT4 trafficking. It is believed that type 2 diabetes could be caused by the modifications in the expression of SNARE complex proteins. The purpose of this study was to evaluate the effect of resveratrol on the expression of these proteins in type 2 diabetes. Materials and Methods: Forty male Wistar rats were selected. Streptozotocin and nicotinamide were applied for the induction of type 2 diabetes. The animals were divided into five groups. Healthy and diabetic groups were set as control; resveratrol (1, 5, and 10 mg/kg body weight) was applied to treat the three groups of diabetic rats for 30 days. Real-time qRT-PCR was applied to evaluate the expression of SNARE complex proteins. Results: There is a link between diabetes and insulin resistance and up-regulation of SNARE proteins expression. Resveratrol improved hyperglycemia and insulin resistance along with a non-significant reduction in the expression of SNARE proteins. Conclusion: Increased expression of SNARE proteins was possibly a compensatory mechanism in response to insulin resistance in the skeletal muscles of diabetic rats. Resveratrol non-significantly reduced the expression of SNARE proteins by enhancing insulin sensitivity, where this effect was dose-dependent. Thus, higher doses of resveratrol and longer intervention periods could probably be more effective. Another molecular mechanism of the anti-diabetic properties of resveratrol was identified with an effect on the expression of SNARE proteins.

Abstract
AIMS To the best of our knowledge, no study has tried to quantitatively summarize the published evidence regarding the effect of hesperidin supplementation on blood glucose control. The present systematic review and meta-analysis of randomized controlled trials aimed to determine the effectiveness of hesperidin supplementation in improving blood glucose control in adults. METHODS Electronic databases including PubMed, ISI Web of Science, Scopus, and Google Scholar were searched up to February 2019. The risk of bias in individual studies was assessed using the Cochrane collaboration's tool. The overall estimates and their 95% confidence intervals (CIs) were calculated using a random-effects model. RESULTS Six trials with 318 participants were reviewed in the present systematic review. The results showed that hesperidin had no significant effect on serum fasting blood glucose (weighted mean difference [WMD] = -1.10 mg/dL, 95% CI: -3.79, 1.57), plasma insulin (WMD = -0.01 μU/mL, 95% CI: -1.20, 1.19), glycated haemoglobin A1c (WMD = -0.04%, 95% CI: -0.14, 0.04), homeostasis model assessment for insulin resistance (WMD = 0.117, 95% CI: -0.06, 0.29) and quantitative insulin sensitivity check index (WMD = 0.135; 95% CI: -0.13, 0.39), with no significant between-study heterogeneity. Subgroup analyses also indicated that the effects were not different based on the studies' design and duration, or the health status of the participants. CONCLUSION Although several animal studies have proposed that hesperidin supplementation might improve blood glucose control, the present study could not confirm this benefit in humans.

Abstract
In this study, we provide a polyphasic characterization of 18 Pseudomonas spp. strains associated with alfalfa leaf spot symptoms in Iran. All of the strains were pathogenic on alfalfa, although the aggressiveness and symptomology varied among the strains. All strains but one were pathogenic on broad bean, cucumber, honeydew, and zucchini, whereas only a fraction of the strains were pathogenic on sugar beet, tomato, and wheat. Syringomycin biosynthesis genes (syrB1 and syrP) were detected using the corresponding PCR primers in all of the strains isolated from alfalfa. Phylogenetic analyses using the sequences of four housekeeping genes (gapA, gltA, gyrB, and rpoD) revealed that all of the strains except one (Als34) belong to phylogroup 2b of P. syringae sensu lato, whereas strain Als34 placed within phylogroup 1 close to the type strain of P. syringae pv. apii. Among the phylogroup 2b strains, nine strains were phylogenetically close to the P. syringae pv. aptata clade, whereas the remainder were scattered among P. syringae pv. atrofaciens and P. syringae pv. syringae strains. Pathogenicity and host range assays of the bacterial strains evaluated in this study on a set of taxonomically diverse plant species did not allow us to assign a "pathovar" status to the alfalfa strains. However, these results provide novel insight into the host range and phylogenetic position of the alfalfa-pathogenic members of P. syringae sensu lato, and they reveal that phenotypically and genotypically heterogeneous strains of the pathogen cause bacterial leaf spot of alfalfa.

Abstract
Cancer therapies using defects in homologous recombination (HR) DNA repair pathway of tumor cells are not yet approved to be applicable in patients with malignancies other than BRCA1/2-mutated tumors. This study was designed to determine the efficacy of combination therapy of a histone deacetylase inhibitor, valproic acid (VPA) and a novel PARP inhibitor AZD2461 in both PC-3 (PTEN-mutated) and DU145 (PTEN-unmutated) prostate cancer cell lines. The Trypan blue dye exclusion assay and the tetrazolium-based colorimetric (MTT) assay were performed to measure the cytotoxicity while combination effects were assessed based on Chou-Talalay's principles. Flow-cytometric assay determined the type of cell death. The real-time PCR analysis was used to evaluate the alterations in mRNA levels of HR-related genes while their protein levels were measured using the ELISA method. γ-H2AX levels were determined as a marker of DNA damage. We observed a synergistic relationship between VPA and AZD2461 in all affected fractions of PC-3 cells (CI<0.9), but not in DU145 cells (CI>1.1). Annexin-V staining analysis revealed a significant induction of apoptosis when PC-3 cells were treated with VPA+AZD2461 (p<0.05). Both mRNA and protein levels of Rad51 and Mre11 were significantly decreased in PC-3 cells co-treated with VPA+AZD2461 while enhanced H2AX phosphorylation was found in PC-3 cells after 12 and 24 hours of co-treatment (p<0.05). Our findings established a preclinical rationale for selective targeting of HR repair pathways by a combination of VPA and AZD2461 as a mechanism for reducing the HR pathway sufficiency in PTEN-mutated prostate cancer cells.

Abstract
Background: Molybden, as a vital and essential micronutrient is directly involved in the metabolism of other elements including carbon, sulfur, and nitrogen. Molybdenum alone is not biologically active unless it binds to specific cofactors. Except for the bacterial nitrogenase, which contains molybdenum-Iron complex, molybdenum cofactor (Moco) is considered as the bioactive component placed in active site regions of molybdenum-containing enzymes. This review aimed to discuss the biological mechanisms involved in molybdenum metabolism highlighting Molybdenum cofactor deficiencies. Methods: Articles indexed in Pubmed, Google Scholar, and Scopus databases were used to extract the required information. Results: Moco, as the cofactor of sulfite oxidase, xanthine dehydrogenase, aldehyde oxidase, and nitrite reductase plays a substantial role in maintaining normal body homeostasis and reactive oxygen species (ROS) production. Lack of Moco is found to be associated with many inborn genetic disorders, such as mental retardation, brain immaturity, nervous shocks, and neurodegenerative diseases. Conclusion: Moco insufficiency compromises normal human body metabolism since it is reported to regulate the metabolic pathways of other elements. Although in recent years, substitution- and gene-therapies have been introduced to restore the metabolic pathways of patients with MoCD type A and B, the definitive treatment for this type of inborn disease has still remained ill-defined. More investigations are needed to completely understand the underlying pathophysiology of molybdenum-related diseases.

Abstract
BACKGROUND Previous studies on the efficacy of platinum-based drugs and selective inhibitors of proteasome have revealed promising outcomes. This study is aimed to evaluate the effects of the combination of cisplatin and carfilzomib on the cell death induction and drug efflux transporters expression in cisplatin-sensitive (A2780s) and cisplatin-resistant (A2780cp) ovarian cancer cells lines. METHODS MTT cytotoxic assay was conducted to determine the cytotoxicity. Drug interactions were analyzed based on Chou-Talalay's principles and real-time PCR analysis was performed to determine possible alterations in mRNA levels of MRP1 and BCRP. RESULTS A2780s cells were more susceptible to both cisplatin and carfilzomib while analyses of drug interactions between the two agents showed synergistic effects in all affected fractions of drug-treated A2780s and A2780cp cells (CI<0.9) with the combination indices being significantly lower in A2780cp cells (p < 0.01). We also found that although mRNA levels of BCRP and MRP1 were significantly altered in both cells exposed to each drug alone, only the combination regimen was able to significantly reduce the mRNA levels of these genes in A2780cp cells (p<0.001). CONCLUSION This combination might be a potential strategy for suppressing cell growth via downregulating the drug efflux transporters expression, especially in cisplatin-resistant ovarian cancer cells (Fig. 3, Ref. 45).

Abstract
BACKGROUND Rapid advances in technology, especially in the field of telecommunication, have led to extraordinary levels of mothers' exposures to radiofrequency electromagnetic fields (RF-EMFs) prior to or during pregnancy. OBJECTIVE The main goal of this study was to answer this question whether exposure of women to common sources of RF-EMFs either prior to or during pregnancy is related to speech problems in the offspring. MATERIALS AND METHODS In this study, mothers of 110 three-to-seven-year-old children with speech problems and 75 healthy children (control group) were interviewed. These mothers were asked whether they had exposure to different sources of EMFs such as mobile phones, mobile base stations, Wi-Fi, cordless phones, laptops and power lines. Chi square test was used to analyze the differences observed between the control and exposed groups. RESULTS Statistically significant associations were found between the use of cordless phone and offspring speech problems for both before pregnancy and during pregnancy maternal exposures (P=0.005 and P=0.014, respectively). However, due to high rate of mobile phone use in both groups, this study failed to show any link between mobile phone use and speech problems in offspring. Furthermore, significant associations were observed between living in the vicinity of power lines and speech problems again for both before pregnancy and during pregnancy maternal exposures (P=0.003 and P=0.002, respectively). However, exposure to other sources of non-ionizing radiation was not linked to speech problems. Moreover, exposure to ionizing radiation (e.g. radiography before and during pregnancy) was not associated with the occurrence of speech problems. CONCLUSION Although this study has some limitations, it leads us to this conclusion that higher-than-ever levels of maternal exposure to electromagnetic fields could be linked to offspring speech problems.

Abstract
Since the early days of human life on the Earth, our skin has been exposed to different levels of light. Recently, due to inevitable consequences of modern life, humans are not exposed to adequate levels of natural light during the day but they are overexposed to relatively high levels of artificial light at night. Skin is a major target of oxidative stress and the link between aging and oxidative stress is well documented. Especially, extrinsic skin aging can be caused by oxidative stress. The widespread use of light emitting diodes (LEDs) and the rapidly increasing use of smartphones, tablets, laptops and desktop computers have led to a significant rise in the exposure of human eyes to short-wavelength visible light. Recent studies show that exposure of human skin cells to light emitted from electronic devices, even for exposures as short as 1 hour, may cause reactive oxygen species (ROS) generation, apoptosis, and necrosis. The biological effects of exposure to short-wavelength visible light in blue region in humans and other living organisms were among our research priorities at the Ionizing and Non-ionizing Radiation Protection Research Center (INIRPRC). Today, there is a growing concern over the safety of the light sources such as LEDs with peak emissions in the blue light range (400-490 nm). Recent studies aimed at investigating the effect of exposure to light emitted from electronic device on human skin cells, shows that even short exposures can increase the generation of reactive oxygen species. However, the biological effects of either long-term or repeated exposures are not fully known, yet. Furthermore, there are reports indicating that frequent exposure to visible light spectrum of the selfie flashes may cause skin damage and accelerated skin ageing. In this paper we have addressed the different aspects of potential effects of exposure to the light emitted from smartphones' digital screens as well as smartphones' photoflashes on premature aging of the human skin. Specifically, the effects of blue light on eyes and skin are discussed. Based on current knowledge, it can be suggested that changing the spectral output of LED-based smartphones' flashes can be introduced as an effective method to reduce the adverse health effects associated with exposure to blue light.

AIM N-3 PUFAs can potentially influence levels of inflammatory and non-inflammatory adipokines. Given the contradictory effects of n-3 PUFAs on serum levels of adipokines in type 2 diabetes, we conducted a systematic review and meta-analysis study of randomized placebo-controlled clinical trials that examined the effects of n-3 PUFAs on serum levels of leptin and adiponectin in patients with type 2 diabetes. METHODS The electronic databases, without regard to language restrictions including PubMed/Medline, Google Scholar, SCOPUS and ISI Web of Science until August 2017, were used to identify randomized controlled trials that assessed the effect of n-3 PUFAs on serum leptin and adiponectin concentrations in type 2 diabetes. Outcomes were extracted based on the mean ± SD as effect size at baseline and end of the intervention. Between-study heterogeneity was evaluated by the I2 estimates and their 95% CIs. Funnel plot asymmetry was used to investigate the existence of publication bias. Stata software and Review Manager were used for statistical data analysis. RESULTS Data from 10 eligible articles involved 494 subjects with type 2 diabetes mellitus (intervention groups = 254 and control groups = 240), with age between 44 and 70 years, treated with doses of 0.52-7.4 g/day n-3 PUFAs. Adiponectin concentration nonsignificantly increased by a MD = 0.17 µg/mL (95% CI - 0.11, 0.44). Also, leptin concentration nonsignificantly reduced by a MD = - 0.31 ng/mL (95% CI - 0.69, 0.07). CONCLUSION Plant and marine sources of n-3 PUFAs can modify serum leptin and adiponectin levels by increasing adiponectin and decreasing leptin levels in patients with type 2 diabetes. Due to some limitations in this study, further studies are needed to reach a definitive conclusion about the effect of n-3 PUFAs on the levels of leptin and adiponectin in T2DM.

Abstract
Diazinon is an organophosphate toxicant that has been identified to induce oxidative stress within biological systems through altering biochemical and hematological indices, by generating free radicals while deteriorating the cellular antioxidant defense system. The present study was designed to evaluate the effectiveness of tert-butylhydroquinone (TBHQ), a synthetic food additive, in serving as an antioxidant against sub-lethal diazinon-induced oxidative stress in male Wistar rats. Animals were randomly divided into 4 groups: Control (treated with corn oil as a vehicle), diazinon (10 mg/kg/day), TBHQ (0.028 g/kg of diet) and a combination group of TBHQ (0.028 g/kg of diet) plus diazinon (10 mg/kg/day). All animals were treated orally once a day by gastric tube and treatments were continued for 7 weeks. Hematological indices, including red blood cell (RBC) indices and white blood cell (WBC) and platelet counts, were measured at the end of the treatment schedule. On comparison of the treatment groups with the untreated control group, RBC count, hemoglobin (Hb), hematocrit (Hct), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) were significantly decreased in the diazinon and TBHQ+diazinon groups, while MCHC in the TBHQ group and MCV in the diazinon and TBHQ+diazinon groups were significantly increased. When the diazinon and TBHQ+diazinon groups were compared with the TBHQ group, RBC, Hb, Hct, and MCHC were significantly decreased whereas MCV was increased in both groups. Additionally, when comparing the TBHQ+diazinon group with the diazinon group, MCHC was determined to be significantly decreased. The results of the current experiments suggested that TBHQ could not efficiently protect blood cells against diazinon toxicity.

Abstract
As a tendency to use new technologies, gadgets such as laptop computers are becoming more popular among students, teachers, businessmen and office workers. Today laptops are a great tool for education and learning, work and personal multimedia. Millions of men, especially those in the reproductive age, are frequently using their laptop computers on the lap (thigh). Over the past several years, our lab has focused on the health effects of exposure to different sources of electromagnetic fields such as cellular phones, mobile base stations, mobile phone jammers, laptop computers, radars, dentistry cavitrons and Magnetic Resonance Imaging (MRI). Our own studies as well as the studies performed by other researchers indicate that using laptop computers on the lap adversely affects the male reproductive health. When it is placed on the lap, not only the heat from a laptop computer can warm men's scrotums, the electromagnetic fields generated by laptop's internal electronic circuits as well as the Wi-Fi Radiofrequency radiation hazards (in a Wi-Fi connected laptop) may decrease sperm quality. Furthermore, due to poor working posture, laptops should not be used on the lap for long hours.

Abstract
According to the World Health Organization (WHO), factors such as growing electricity demand, ever-advancing technologies and changes in social behaviour have led to steadily increasing exposure to man-made electromagnetic fields. Dental amalgam fillings are among the major sources of exposure to elemental mercury vapour in the general population. Although it was previously believed that low levels are mercury (i.g. release of mercury from dental amalgam) is not hazardous, now numerous data indicate that even very low doses of mercury cause toxicity. There are some evidence indicating that perinatal exposure to mercury is significantly associated with an increased risk of developmental disorders such as autism spectrum disorders (ASD) and attention-deficit hyperactivity disorder (ADHD). Furthermore, mercury can decrease the levels of neurotransmitters dopamine, serotonin, noreprenephrine, and acetylcholine in the brain and cause neurological problems. On the other hand, a strong positive correlation between maternal and cord blood mercury levels is found in some studies. We have previously shown that exposure to MRI or microwave radiation emitted by common mobile phones can lead to increased release of mercury from dental amalgam fillings. Moreover, when we investigated the effects of MRI machines with stronger magnetic fields, our previous findings were confirmed. As a strong association between exposure to electromagnetic fields and mercury level has been found in our previous studies, our findings can lead us to this conclusion that maternal exposure to electromagnetic fields in mothers with dental amalgam fillings may cause elevated levels of mercury and trigger the increase in autism rates. Further studies are needed to have a better understanding of the possible role of the increased mercury level after exposure to electromagnetic fields and the rate of autism spectrum disorders in the offspring.

Abstract
BACKGROUND Nowadays, mothers are continuously exposed to different sources of electromagnetic fields before and even during pregnancy. It has recently been shown that exposure to mobile phone radiation during pregnancy may lead to adverse effects on the brain development in offspring and cause hyperactivity. Researchers have shown that behavioral problems in laboratory animals which have a similar appearance to ADHD are caused by intrauterine exposure to mobile phones. OBJECTIVE The purpose of this study was to investigate whether the maternal exposure to different sources of electromagnetic fields affect on the rate and severity of speech problems in their offspring. METHODS In this study, mothers of 35 healthy 3-5 year old children (control group) and 77 children and diagnosed with speech problems who had been referred to a speech treatment center in Shiraz, Iran were interviewed. These mothers were asked whether they had exposure to different sources of electromagnetic fields such as mobile phones, mobile base stations, Wi-Fi, cordless phones, laptops and power lines. RESULTS We found a significant association between either the call time (P=0.002) or history of mobile phone use (months used) and speech problems in the offspring (P=0.003). However, other exposures had no effect on the occurrence of speech problems. To the best of our knowledge, this is the first study to investigate a possible association between maternal exposure to electromagnetic field and speech problems in the offspring. Although a major limitation in our study is the relatively small sample size, this study indicates that the maternal exposure to common sources of electromagnetic fields such as mobile phones can affect the occurrence of speech problems in the offspring.

Abstract
BACKGROUND Millions of people in the world have diabetes mellitus and its prevalence is growing. Oxidative stress, advanced glycation end-products (AGEs) and receptor for advanced glycation end-products (RAGE) play key role in the pathogenesis of diabetes. New and safe strategies of remedy are needed for this disease. OBJECTIVES We hypothesized that resveratrol may exert a renal protective effect on diabetic rats. MATERIALS AND METHODS Male rats with diabetes were treated with or without resveratrol as 1, 5, 10 mg/kg of body weight for 30 days. The total AGEs and malondialdehyde levels in kidney tissues were determined by spectrofluorimetric method and the insulin level was assayed using ELISA. The total antioxidant capacity contents in kidney and the glucose in plasma were measured by a colorimetric assay. The expression of RAGE was assayed in kidneys of all animals using quantitative PCR. RESULTS In resveratrol-treated rats with diabetes, malondialdehyde levels, plasma glucose and expression of RAGE were significantly reduced compared with the untreated group. Moreover, the total antioxidant and insulin levels significantly increased in treated rats. There was no significant difference in the AGEs contents among all the groups. CONCLUSIONS These results revealed that resveratrol has beneficial effects on kidney by extenuating the oxidative stress and down-regulation of RAGE expression.

Abstract
OBJECTIVE Cognitive factors and anticipation are known to influence food intake. The current study examined the effect of anticipation and actual consumption of food on hormone (ghrelin, cortisol, and insulin) and glucose levels, appetite and ad libitum intake, to assess whether changes in hormone levels might explain the predicted differences in subsequent food intake. DESIGN AND METHODS During four breakfast sessions, participants consumed a yogurt preload that was either low caloric (LC: 180 kcal/300 g) or high caloric (HC: 530 kcal/300 g) and was provided with either consistent or inconsistent calorie information (i.e., stating the caloric content of the preload was low or high). Appetite ratings and hormone and glucose levels were measured at baseline (t = 0), after providing the calorie information about the preload (t = 20), after consumption of the preload (t = 40), and just before ad libitum intake (t = 60). RESULTS Ad libitum intake was lower after HC preloads (as compared to LC preloads; P < 0.01). Intake after LC preloads was higher when provided with (consistent) LC information (467±254 kcal) as compared to (inconsistent) HC information (346±210 kcal), but intake after the HC preloads did not depend on the information provided (LC information: 290±178 kcal, HC information: 333±179 kcal; caloric load*information P = 0.03). Hormone levels did not respond in an anticipatory manner, and the post-prandial responses depended on actual calories consumed. CONCLUSIONS These results suggest that both cognitive and physiological information determine food intake. When actual caloric intake was sufficient to produce physiological satiety, cognitive factors played no role; however, when physiological satiety was limited, cognitively induced satiety reduced intake to comparable levels.

Abstract
Granulocyte-macrophage colony-stimulating factor (GM-CSF) as an adjuvant in autologous cell-based anti-tumor immunotherapy has recently been approved for clinical application. To avoid the need for individualized processing of autologous cells, we developed a novel strategy based on the encapsulation of GM-CSF-secreting human allogeneic cells. GM-CSF-producing K562 cells showed high, stable and reproducible cytokine secretion when enclosed into macrocapsules. For clinical development, the cryopreservation of these devices is critical. Thawing of capsules frozen at different time points displayed differences in GM-CSF release shortly after thawing. However, similar secretion values to those of non-frozen control capsules were obtained 8 days after thawing at a rate of >1000 ng GM-CSF per capsule every 24 h. For future human application, longer and reinforced capsules were designed. After irradiation and cryopreservation, these capsules produced >300 ng GM-CSF per capsule every 24 h 1 week after thawing. The in vivo implantation of encapsulated K562 cells was evaluated in mice and showed preserved cell survival. Finally, as a proof of principle of biological activity, capsules containing B16-GM-CSF allogeneic cells implanted in mice induced a prompt inflammatory reaction. The ability to reliably achieve high adjuvant release using a standardized procedure may lead to a new clinical application of GM-CSF in cell-based cancer immunization.

Abstract
OBJECTIVE von Willebrand factor (VWF) is acutely released from endothelial cells in response to numerous calcium-raising agents (e.g. thrombin, histamine) and cAMP-raising agents (e.g. epinephrine, adenosine, vasopressin). In contrast, very few inhibitors of endothelial VWF secretion have been described. The neurotransmitter dopamine is a modulator of exocytosis in several endocrine cells, and is possibly involved in the regulation of several endothelial cell functions. We therefore investigated the effect of dopamine on endothelial VWF secretion. RESULTS Dopamine, D2/D3- and D4-specific agonists inhibited histamine- but not thrombin-induced VWF secretion. Expression of dopamine D2, D3 and D4 receptors was demonstrated by reverse transcription polymerase chain reaction (RT-PCR) in both human aortic (HAEC) and umbilical vein (HUVEC) endothelial cells. D2-D4 agonists did not inhibit histamine-induced rise in [Ca(2+)](i): they inhibited histamine-induced secretion even in the absence of extracellular calcium. Thus, the dopamine effects are not mediated by [Ca(2+)](i)-dependent signalling. D2/D3- and D4-specific agonists inhibited neither the rise in cAMP nor VWF secretion in response to epinephrine and adenosine, arguing against an effect on cAMP-mediated signalling. D1 and D5 receptors were not detected in HAEC or HUVEC by RT-PCR, and the D1/D5-specific agonist SKF 38 393 failed to modulate VWF secretion, arguing against a role for these receptors in endothelial exocytosis. CONCLUSIONS Dopamine inhibits histamine-induced endothelial exocytosis by activating D2-D4 receptor, via a mechanism distinct from [Ca(2+)](i)-or cAMP-mediated signaling. In contrast, D1 and D5 receptors are not functionally expressed in cultured endothelial cells. Dopamine agonists may be useful as inhibitors of endothelial activation in inflammation and cardiovascular disease.
