Abstract
Today, the main goal of many researchers is the use of high-performance, economically and industrially justified materials, as well as recyclable materials in removing organic and dangerous pollutants. For this purpose, sol-gel derived carbon aerogel modified with nickel (SGCAN) was used to remove Cefixime from aqueous solutions. The influence of important parameters in the cefixime adsorption onto SGCAN was modeled and optimized using artificial neural network (ANN), response surface methodology (RSM), genetic algorithm (GA), and SOLVER methods. R software was applied for this purpose. The design range of the runs for a time was in the range of 5 min-70 min, concentration in the range of 5 mg L-1 to 40 mg L-1, amount of adsorbent in the range of 0.05 g L-1 to 0.15 g L-1, and pH in the range of 2.0-11. The results showed that the ANN model due to lower Mean Squared Error (MSE), Sum of Squared Errors (SSE), and Root Mean Squared Error (RMSE) values and also higher R2 is a superior model than RSM. Also, due to the superiority of ANN over the RSM model, the optimum results were calculated based on GA. Based on GA, the highest Cefixime adsorption onto SGCAN was obtained in pH, 5.98; reaction time, 58.15 min; initial Cefixime concentration, 15.26 mg L-1; and adsorbent dosage, 0.11 g L-1. The maximum adsorption capacity of Cefixime onto SGCAN was determined to be 52 mg g-1. It was found the pseudo-second-order model has a better fit with the presented data.

Abstract
BACKGROUND Nicotine, the main compound of smoking may exert its effects by changing the expression of microRNAs (miRNAs). This study was conducted to further investigate the molecular mechanisms of miRNA-dependent effects of nicotine in an animal model of liver fibrosis. METHODS The bile duct ligation (BDL) approach was used to create a model of liver fibrosis. Twenty-four male Wistar rats were used in the study. The effects of nicotine administration on miRNA-124 expression, as well as alpha-smooth muscle actin (liver fibrosis marker) and chemokine ligand 2 (an inflammatory chemokine), were investigated using RT-qPCR. In addition, the mRNA and protein expression of signal transducer and activator of transcription 3 (STAT-3; as a potential target for miRNA-124) were investigated by RT-qPCR and immunofluorescence, respectively. Liver enzyme activity levels were measured using a colorimetric assay. In addition, the effects of nicotine on the process of liver fibrosis were investigated with histological studies. RESULTS The development of liver fibrosis in BDL rats and nicotine administration led to a decrease in miRNA-124 expression. The decrease in the expression is accompanied by the increase in the expression of fibrotic and proinflammatory genes. Also, an increase in STAT-3 mRNA and protein expression was observed in the fibrotic rats that received nicotine. In addition, the significant increase in bilirubin and liver enzymes in fibrotic rats worsens with nicotine administration. The results of histological studies also confirm these results. CONCLUSION Considering that miRNA-124 is an anti-inflammatory miRNA, it can be concluded that the decrease in its expression due to nicotine exposure leads to an increase in inflammatory processes and subsequently to an increase in liver fibrosis.

Abstract
Alcoholic liver disease (ALD) and non-alcoholic fatty liver disease (NAFLD) are common causes of chronic liver disease that share the range of steatosis, steatohepatitis, fibrosis, cirrhosis, and finally, hepatocellular carcinoma. They are identified by the dysregulation of disease-specific signalling pathways and unique microRNAs. Capsaicin is an active ingredient of chilli pepper that acts as an agonist of transient receptor potential vanilloid subfamily 1. It seems that the protective role of capsaicin against NAFLD and ALD is linked to its anti-steatotic, antioxidant, anti-inflammatory, and anti-fibrotic effects. Capsaicin-induced inhibiting metabolic syndrome and gut dysbiosis and increasing bile acids production are also involved in its anti-NAFLD role. This review summarises the different molecular mechanisms underlying the protective role of capsaicin against NAFLD and ALD. More experimental studies are needed to clarify the effects of capsaicin on the expression of genes involved in hepatic lipid metabolism and hepatocytes apoptosis in NAFLD and ALD.

Abstract
Objectives Aging and stress synergistically induce behavioral dysfunctions associated with oxidative and endoplasmic reticulum (ER) stress in brain regions. Considering the rejuvenating effects of young plasma on aging brain function, in the current study, we examined the effects of young plasma administration on anxiety-like behavior, NADH oxidase, NADPH oxidase, and ER stress markers in the hippocampus of old male rats. Materials and Methods Young (3 months old) and aged (22 months old) rats were randomly assigned into five groups: young control (Y), aged control (A), aged rats subjected to chronic stress for four weeks (A+S), aged rats subjected to chronic stress and treated with old plasma (A+S+OP), and aged rats subjected to chronic stress and treated with young plasma (A+S+YP). Systemic injection of (1 ml) young and old plasma was performed for four weeks (3 times/week). Results Young plasma transfusion significantly improved anxiety-like behavior in aged rats and modulated oxidative stress in the hippocampus, evidenced by the increased NADH oxidase (NOX) activity and the reduced NADPH oxidase. In addition, the levels of C/EBP homologous protein (CHOP) and Glucose-Regulated Protein 78 (GRP-78), as ER stress markers, markedly reduced in the hippocampus following the administration of young plasma. Conclusion These findings suggest that young plasma transfusion could reverse anxiety-like behavior in stress-exposed aged rats by modulating the hippocampal oxidative and ER stress markers.

Abstract
Along with altering brain responses to stress, aging may also impair recovery from depression symptoms. In the present study, we investigated depressive-like behaviors in young and aged rats and assayed the levels of microRNA-101 (miR-101), Rac1/RhoA, PSD-95, and GluR1 in the prefrontal cortex (PFC) after stress cessation and after a recovery period. Young (3 months old) and aged (22 months old) male Wistar rats were divided into six groups; Young control (YNG), young rats received chronic stress for four weeks (YNG + CS), young rats received chronic stress for four weeks followed by a 6-week recovery period (YNG + CS + REC), Aged control (AGED), aged rats received chronic stress for four weeks (AGED + CS), and aged rats received chronic stress for four weeks followed by a 6-week recovery period (AGED + CS + REC). Stress-induced depression, evaluated by the sucrose preference test (SPT) and forced swimming test (FST), was yet observed after the recovery period in aged but not in young rats, which were accompanied by unchanged levels of miR-101, Rac1/RhoA, GluR1, and PSD-95 in the PFC of aged rats. These data suggested that impaired synaptic plasticity of glutamatergic synapses via the miR-101/Rac1/RhoA pathway may contribute to the delayed behavioral recovery after stress exposure observed in aging animals.

Abstract
Hypoxia, especially the chronic type, leads to disruptive results in the brain that may contribute to the pathogenesis of some neurodegenerative diseases such as Alzheimer's disease (AD). The ventrolateral medulla (VLM) contains clusters of interneurons, such as the pre-Bötzinger complex (preBötC), that generate the main respiratory rhythm drive. We hypothesized that exposing animals to chronic sustained hypoxia (CSH) might develop tauopathy in the brainstem, consequently changing the rhythmic manifestations of respiratory neurons. In this study, old (20-22 months) and young (2-3 months) male rats were subjected to CSH (10 ± 0.5% O2) for ten consecutive days. Western blotting and immunofluorescence (IF) staining were used to evaluate phosphorylated tau. Mitochondrial membrane potential (MMP or ∆ψm) and reactive oxygen species (ROS) production were measured to assess mitochondrial function. In vivo diaphragm's electromyography (dEMG) and local field potential (LFP) recordings from preBötC were employed to assess the respiratory factors and rhythmic representation of preBötC, respectively. Findings showed that ROS production increased significantly in hypoxic groups, associated with a significant decline in ∆ψm. In addition, tau phosphorylation elevated in the brainstem of hypoxic groups. On the other hand, the power of rhythms declined significantly in the preBötC of hypoxic rats, parallel with changes in the respiratory rate, total respiration time, and expiration time. Moreover, there was a positive and statistically significant correlation between LFP rhythm's power and inspiration time. Our data showed that besides CSH, aging also contributed to mitochondrial dysfunction, tau hyperphosphorylation, LFP rhythms' power decline, and changes in respiratory factors.

Abstract
Cigarette smoking is a harmful habit that is widespread around the world. It is among the well-known lifestyle-related risk factors for many diseases. Nicotine, as its principal constituent, has various detrimental, and beneficial functions. Nicotinic acetylcholine receptors (nAChRs), which are present in nearly all body cells, are how nicotine works. Numerous investigations have demonstrated that nicotine causes abnormal microRNA expression (miRNAs). These short sequences of RNAs are known to regulate gene expression post-transcriptionally. A wide range of miRNAs are modulated by nicotine, and nicotine-induced miRNA changes could subsequently mediate nicotine's effect on gene expression regulation. We will focus on the reciprocal interaction between nAChRs and miRNAs and describe the essential targets of these dysregulated miRNAs after nicotine exposure and activation of nAChRs. It appears that crucial subcellular mechanisms implicated in nicotine's effects are miRNA-related pathways. It is crucial to investigate the molecular mechanism underlying the effects of nicotine as well as the dysregulation of miRNA following nAChR activation. The finding about epigenetic mechanisms of nicotine-induced effects may shed light on the establishment of new treatment strategies to prevent the harmful effects of nicotine and perhaps may augment the beneficial effects in diverse smoking-related diseases.

Abstract
In the indoor environment of dental clinics, dental personnel and patients are exposed to a risk of infection because of the transmission of SARS-CoV-2 via particles or droplets. This study investigated the presence of SARS-CoV-2 RNA in indoor air of dental clinics in Tehran, Iran. Air sampling was done (n = 36) collecting particulate samples on PTFE filters at flow rates of 30 to 58 L/min. The samples were analyzed with novel coronavirus nucleic acid diagnostic real-time PCR kits. Only 13 out of 36 samples were positive for SARS-CoV-2 RNA. Logistic regression showed that sampling site's volume, PM2.5 concentration, number of people, and number of active patient treatment units were significantly positively related with the presence of SARS-CoV-2 RNA. Thus, strategies to control the spread of COVID-19 should include reducing the number of infected people in dental clinics, adding filtration systems, and/or improving ventilation conditions.

Abstract
Objective: Non-alcoholic fatty liver disease (NAFLD) is one of the main risk factors for cardiovascular mortality and morbidity. This study, for the first time, explored the effects of trans-chalcone on cardiac expressions of myocardial fibrosis-related genes, including transforming growth factor -β1 (TGF-β1), connective tissue growth factor (CTGF/CCN2), and collagen type I.Materials and methods: Twenty-eight rats were randomly divided into four groups: control, received 10% tween 80; chalcone, received trans-chalcone; HFD, received high-fat diet (HFD) and 10% tween 80; HFD + chalcone, received HFD and trans-chalcone, by once-daily gavage for 6 weeks. Finally, cardiac expression levels of TGF-β1, CTGF, and collagen type I were determined.Results: HFD feeding increased mRNA levels of collagen type I, TGF-β1, and CTGF in the heart of rats. However, trans-chalcone inhibited HFD-induced changes.Conclusions: trans-Chalcone can act as a cardioprotective compound by inhibiting TGF-β1 and CTGF-dependent stimulation of collagen type I synthesis in the heart of HFD-fed rats.

Abstract
Background Following Spinal Cord Injury (SCI), innumerable inflammatory and degenerative fluctuations appear in the injured site, and even remotely in manifold areas of the brain. Howbeit, inflammatory, degenerative, and oscillatory changes of motor cortices have been demonstrated to be due to SCI, according to recent studies confirming the involvement of cognitive areas of the brain, such as hippocampus and prefrontal cortex. Therefore, addressing SCI induced cognitive complications via different sights can be contributory in the treatment approaches. Results Herein, we used 16 male Wistar rats (Sham = 8, SCI = 8). Immunohistochemical results revealed that spinal cord contusion significantly increases the accumulation of alpha-synuclein and decreases the expression of Doublecortin (DCX) in the hippocampal regions like Cornu Ammonis1 (CA1) and Dentate Gyrus (DG). Theses degenerative manifestations were parallel with a low expression of Achaete-Scute Family BHLH Transcription Factor 1 (ASCL1), SRY (sex determining region Y)-box 2 (SOX2), and dopaminergic receptors (D1 and D5). Additionally, based on the TUNEL assay analysis, SCI significantly increased the number of apoptotic cells in the CA1 and DG regions. Cognitive function of the animals was assessed, using the O-X maze and Novel Object Recognition (NORT); the obtained findings indicted that after SCI, hippocampal neurodegeneration significantly coincides with the impairment of learning, memory and recognition capability of the injured animals. Conclusions Based on the obtained findings, herein SCI reduces neurogenesis, decreases the expression of D1 and D5, and increases apoptosis in the hippocampus, which are all associated with cognitive function deficits.

Abstract
Background Congenital cardiovascular malformation is the most common group of birth defects. Fetal echocardiography is highly sensitive and specific in the diagnosis of congenital heart disease in low- and high-risk populations. Objective This study aimed to assess abnormal findings in fetal echocardiography and maternal disease. Materials and Methods This cross-sectional study was performed on 114 pregnant women referred to Afshar hospital, Yazd, Iran from October 2016 to March 2017. All pregnant women underwent fetal echocardiography through fetal heart screening protocol, which is administered by the international society of ultrasound in obstetrics and gynecology guidelines. Data collected included referral cause, gestational age, maternal age, gravida, and final diagnosis after an accurate fetal echocardiography. Results The mean gestational age was 20 wk. The most common referral cause of pregnant women included diabetes (36.8%), fetal arrhythmia (14%), high maternal age (7%), and echogenic focus on ultrasound (6.1%). The most common postpartum findings were normal (68.4%), cardiac abnormalities (17.6%), and arrhythmias (14%). In postnatal echocardiography, the results were consistent with fetal echocardiography except in 2 women. Conclusion This study showed that fetal echocardiography can be used in the early diagnosis and treatment of congenital heart diseases.

Abstract
AIMS The association between asthma and obesity has been shown but its accurate mechanism is unknown. In the current study, we sought to investigate the gene expression levels of IL-17/TRAF6/MAPK/USP25 axis and pro-inflammatory cytokine level (IL-6, IL-1β, and TNF-α) in obese Ovalbumin (OVA)-sensitized female and male Wistar rats lung tissue. MAIN METHODS Animals in both males and females were divided into eight groups (four groups in each sex) based on diet and OVA-sensitization: normal diet, a normal diet with OVA-sensitization, high-fat diet (HFD), and OVA-sensitization with an HFD. KEY FINDINGS In both sexes, obese OVA-sensitized rats, the methacholine concentration-response curve shifted to the left and EC50 methacholine decreased. Increased pro-inflammatory cytokines as well as elevated IL-17/TRAF6/MAPK axis genes and decreased USP25 gene expression were identified in obese OVA-sensitized groups. SIGNIFICANCE The results indicate that in obese OVA-sensitized rats, the IL-17 axis were involved in the pathogenesis of the disease and can be considered as a therapeutic target in subjects with obesity-related asthma.

Abstract
OBJECTIVE Hypoxia is the main stimulus for angiogenesis. Hypoxia-inducible factor (HIF)-1α, vascular endothelial growth factor (VEGF), and miR-210 are involved in the hypoxia-induced angiogenesis. This study examined the effects of hypoxia and/or ghrelin on miR-210, HIF-1α, and VEGF levels in the heart of rats. METHODS Wistar rats were randomly divided into 4 groups (n = 6): control; ghrelin, received daily intraperitoneal injections of ghrelin; hypoxia, was exposed to hypoxic condition; hypoxia + ghrelin, was exposed to hypoxic condition and received intraperitoneal injections of ghrelin, for 2 weeks. Myocardial angiogenesis, the expression level of miR-210, and protein levels of HIF-1α and VEGF were assayed in the heart samples. RESULTS Hypoxia increased myocardial angiogenesis and cardiac levels of miR-210, HIF-1α, and VEGF. However, ghrelin inhibited these hypoxia-induced changes. Interestingly, ghrelin had no significant effect on miR-210, HIF-1α, and VEGF levels in normoxic condition. CONCLUSION Ghrelin may be useful as an anti-angiogenic factor.

Abstract
INTRODUCTION Kawasaki disease(KD) is a vasculitis of childhood that tends to influence the coronary arteries. There is no national data about the prevalence of KD in Iran. This study aimed to perform a national registry in Iran for 13 years. METHODS In this retrospective study, the data for KD extracted from medical records of <19 year-old patients admitted to tertiary hospitals in Iran between 2007 and 2019 were recorded in the national KD registry system. Age, admission date, gender, location, and presence of KD criteria, laboratory and echocardiography findings, and treatment modalities were evaluated. Complete KD was considered if ≥4 clinical criteria of the KD existed and otherwise, incomplete KD was considered. RESULTS Data from 1,682 KD patients including 999(59.39%) boys and 683(40.61%) girls and male/female ratio of 1.46 were evaluated. The mean age was 3.08 ± 2.49 years and 1465(87%) were living in urban regions. The yearly incidence of the disease was between 2.62 to 3.03 from 2015 to 2019. The highest age-specific incidence was observed in children <1-year-old. Incomplete and resistant KD included 1,321(78.54%) and 9(0.54%) patients, respectively. Abnormal echocardiography was detected in 619(36.80%) patients. Leukocytosis, with dominancy of neutrophils, anemia, thrombocytosis and increased ESR and CRP were the most noticeable laboratory findings. No death due to KD disease was reported. CONCLUSION Based on this study, most of the KD cases are presented with atypical presentation in Iran. So, increasing awareness of primary healthcare workers by educating and updating their data is very important in timely diagnosis and management of the disease.

Abstract
Pathophysiology of depression in elderlies is linked to aging-associated increase in indoleamine 2,3-dioxygenase (IDO) levels and activity and kynurenine (Kyn) metabolites. Moreover, these aging-induced changes may alter the brain's responses to stress. Growing evidence suggested that young plasma can positively affect brain dysfunctions in old age. The present study aimed to investigate whether the antidepressant effects of young plasma administration in aged rats subjected to chronic unpredictable mild stress (CUMS) and underlying mechanisms, focusing on the prefrontal cortex (PFC). Young (3 months old) and aged (22 months old) male rats were divided into five groups; young control, aged control, aged rats subjected to CUMS (A + CUMS), aged rats subjected to CUMS and treated with young plasma (A + CUMS + YP), and aged rats subjected to CUMS and treated with old plasma (A + CUMS + OP). Plasma was injected (1 ml, intravenously) three times per week for four weeks. Young plasma significantly improved CUMS-induced depressive-like behaviors, evidenced by the increased sucrose consumption ratio in the sucrose preference test and the reduced immobility time in the forced swimming test. Furthermore, young plasma markedly reduced the levels of interferon-gamma (IFN-γ), IDO, Kyn, and Kyn to tryptophan (Kyn/Trp) ratio in PFC tissue. Expression levels of the serotonin transporter and growth-associated protein (GAP)-43 were also significantly increased after chronic administration of young plasma. These findings provide evidence for the antidepressant effect of young plasma in old age; however, whether it improves depressive behaviors or faster recovery from stress-induced deficits is required to be elucidated.

Abstract
NEW FINDINGS What is the central question of this study? Young plasma contains several rejuvenating factors that exert beneficial effects in ageing and neurodegenerative diseases: can repeated transfusion of young plasma improve depressive behaviour in aged rats? What is the main finding and its importance? Following chronic transfusion of young plasma, depressive behaviour was improved in the depression model of aged rats, which was associated with reduced apoptosis process in the prefrontal cortex. ABSTRACT Brain ageing alters brain responses to stress, playing an essential role in the pathophysiology of late-life depression. Moreover, apoptotic activity is up-regulated in the prefrontal cortex in ageing and stress-related mood disorders. Considerable evidence suggests that factors in young blood could reverse age-related dysfunctions in organs, especially in the brain. Therefore, this study investigated the effect of young plasma administration on depressive behaviours in aged rats exposed to chronic unpredictable mild stress (CUMS), with a focus on the apoptosis process. Young (3 months old) and aged (22 months old) male rats were randomly assigned into four groups: young control (YC), aged control (AC), aged rats subjected to CUMS (A+CUMS) and aged rats subjected to CUMS and treated with young plasma (A+CUMS+YP). In the A+CUMS and A+CUMS+YP groups, CUMS was used to generate the depression rat model. Moreover, the A+CUMS+YP group received pooled plasma (1 ml, intravenously), collected from young rats, three times per week for 4 weeks. Young plasma administration significantly improved CUMS-induced depression-like behaviours, including decreased sucrose consumption ratio, reduced locomotor activity and prolonged immobility time. Importantly, young plasma reduced neuronal apoptosis in the prefrontal cortex that was associated with reduced TUNEL-positive cells and cleaved caspase-3 protein levels in the A+CUMS+YP compared with the A+CUMS group. Young plasma can partially improve the neuropathology of late-life depression through the apoptotic signalling pathways.

Abstract
Purpose: Non-alcoholic steatohepatitis (NASH) is an inflammatory disorder and an aggressive form of fatty liver disease. Certain microRNAs, including miR-122, 21, 34a, and 451, are involved in the transition from steatosis to NASH. This study examined how trans-chalcone (the core of chalcone derivatives) affects NAFLD progression by regulating miRNAs. Methods: Male rats were divided into three groups (n = 7/group) as follows: control, rats were gavaged with 10% tween 80 (for two weeks); NASH, rats were gavaged with a high-fat liquid diet (HFD; for six weeks) and 10% tween 80 (for two weeks); NASH + Chal, rats were gavaged with the HFD (for six weeks) and trans-chalcone (for two weeks). Hepatic expression levels of miR-122, 21, 34a, and 451 were determined. Results: trans-Chalcone reversed histological abnormalities, reduced liver injury markers, and attenuated insulin resistance in HFD-fed rats. In the liver, HFD-induced NASH increased the expression level of miR-34a and decreased expression levels of miR-122, 21, and 451. However, trans-chalcone inhibited HFD-induced changes in expression levels of these miRNAs.
Conclusion: trans-Chalcone could inhibit the transition from steatosis to NASH through the modulation of miR-122, 21, 34a, and 451 expression levels in the liver.

Abstract
High-fat diet (HFD) intake is linked to chronic kidney disease. Farnesoid X receptor (FXR) controls the renal lipid metabolism and fibrosis. The purpose of the current study was to evaluate the possible impacts of trans-chalcone on HFD-induced changes in renal lipid metabolism and Smad-3 expression through the regulation of FXR expression. To this aim, 28 rats were randomly divided into control, chalcone, HFD, and HFD + chalcone groups. At the end of treatments, renal FXR, sterol regulatory element-binding protein (SREBP)-1c, fatty acid synthase (FAS), Smad-3, and neutrophil gelatinase-associated lipocalin (NGAL) expression levels were assayed. Moreover, insulin sensitivity check index (QUICKI) was calculated. trans-Chalcone significantly inhibited HFD-induced reduction of insulin sensitivity. Moreover, HFD decreased the FXR expression, and trans-chalcone reversed this change. trans-Chalcone also inhibited HFD-induced increases in expression levels of SREBP-1c, FAS, Smad-3, and NGAL. Therefore, trans-chalcone, as a renoprotective agent, inhibits HFD-induced disturbances in FXR/SREBP-1c/FAS and FXR/Smad-3 pathways. PRACTICAL APPLICATIONS: Non-alcoholic fatty liver disease and metabolic syndrome, two health concerns with increasing prevalence, are known as important risk factors for chronic kidney disease. The current study indicated the preventive effect of trans-chalcone administration on HFD-induced disturbances in renal FXR/SREBP-1c/FAS and FXR/Smad-3 pathways. According to these results, trans-chalcone can be regarded as a renoprotective functional food component that can protect individuals with metabolic syndrome against chronic renal disease.

Abstract
BACKGROUND AND OBJECTIVE Overweight and obesity are thought to be associated with increased risk of chronic disease in the Middle East. The present study aimed to determine the association between dietary habits and the incidence of overweight and obesity in urban adult population in the central part of Iran after a 10-year follow-up. METHODS This cohort study was initiated with 2000 participation aged 20-74 years from Yazd city in Iran based on Yazd Healthy Heart Project (YHHP). The participants without overweight and obesity at the baseline of the study were followed up to 10 years. Demographic data, anthropometric measurements, behavioral and metabolic risk factors of cardiovascular diseases and dietary habits were assessed at baseline and phase II. RESULTS After a 10-year follow up, 516 non-overweight and 1068 non-obese participants were included for the final analysis. Once adjustments were made for all potential confounders including age, sex, smoking, economic status, physical activity and education, it was identified that lack of weight control increased the risk of obesity (hazard ratio; 95% CI) in total population (1.9; 1.06, 3.4), as well as the risk of overweight (2.39; 1.07, 5.27) and obesity (2.65; 1.13, 6.25) in men. Moreover, consumption of mayonnaise increased the 10-year risk of overweight in women (6.09; 1.2, 30.99). CONCLUSIONS As revealed by the present study, unhealthy dietary habits can increase the incidence of overweight and obesity in central part of Iran. Therefore, changing the lifestyle appears to be urgent in reducing the risk of overweight and obesity.

Abstract
Objective: Hormones consumption in women who conceive through in vitro fertilization (IVF) as well as embryonic manipulations have raised concerns regarding the neonates’ health, including the possibility of pulmonary hypertension. This study, therefore, aimed to assess the pulmonary arterial pressure in at-term IVF neonates. Materials and Methods: This prospective cross-sectional study was conducted between March 2013 and October 2017 and compares 160 IVF neonates (group 1) with 160 naturally conceived neonates (group 2). The neonates in both groups were cesarean newborns, matched in terms of gestational and neonatal age. The neonates were three-seven days old, had a full-term gestational age of 37-39 weeks and 6 days, and a normal birth weight of 2500-4000 gr. The systolic pulmonary artery pressure (SPAP) was estimated using real-time echocardiography on the basis of peak flow velocity of tricuspid regurgitation jet. Results: A significant difference was observed in the mean SPAPs between the two groups (p<0.001). Although, the effect of gestational age on reducing SPAP was greater and statistically significant in group 1, the gradual decrease in the PAP after birth appeared to be slower in this group. Moreover, in both groups, the effect of gestational age on reducing SPAP was more convincing than that of the neonatal age. Further, in both groups, a significant reverse correlation was observed between the SPAP and the neonatal weight; however, it appeared to be markedly higher in group 1. Conclusion: Our study renders IVF as being culpable in the incidence of pulmonary hypertension among neonates. Hence, to detect the likelihood of pulmonary arterial hypertension in IVF neonates, it is recommended to monitor their PAP during the neonatal period, and thereby facilitate them with the required treatment.

Abstract
High-fat diet (HFD) increases the risk of non-communicable inflammatory diseases including pulmonary disorders. Trans-chalcone is a chalcone with antioxidant and anti-inflammatory effects. This study aimed to explore the effect of this natural compound and molecular mechanism of its effect on HFD-induced pulmonary inflammation. Twenty-eight male Wistar rats were randomly divided into four main groups (n = 7 per each group): control, receiving 10% tween 80; Chal, receiving trans-chalcone, HFD, receiving a high-fat emulsion and 10% tween 80; HFD + Chal, receiving a high-fat emulsion and trans-chalcone. After 6 weeks, the lungs were dissected, and the expression levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6), and miR-146a were determined using real-time PCR. Moreover, histological analysis was done by hematoxylin and eosin staining. Significant elevations in TNF-α, IL-1β, IL-6, and miR-146a expression levels (P < 0.001) were observed within the lungs of HFD-fed rats compared with the control. However, oral administration of trans-chalcone reduced TNF-α, IL-1β, IL-6 (P < 0.001), and miR-146a (P < 0.05) expression levels and also improved HFD-induced histological abnormalities. These findings indicate that trans-chalcone ameliorates lung inflammatory response and structural alterations. It seems that this beneficial effect is associated with the down-regulation of pro-inflammatory cytokines and miR-146a.

Abstract
The aim of this study was to evaluate the effect of prolonged dietary nitrate supplementation on the gonadotropin level, testicular histology and morphometry, expression of miR-34b and p53 mRNA, and spermatogenesis in streptozotocin-induced diabetic male rats. METHODS Fifty male Wistar rats were divided into 5 groups: Control (C), control + nitrate (CN), diabetes (D), diabetes + insulin (DI), and diabetes + nitrate (DN). Diabetes was induced using 45 mg kg-1 of streptozotocin intraperitoneally. Rats in the CN and DN groups were administered sodium nitrate in drinking water (100 mg L-1). NPH insulin (2-4 U d-1) was injected subcutaneously in the DI group for 2 months. Nitrate and insulin supplementation was started one month after confirmation of diabetes. RESULTS Nitrate supplementation in the DN group significantly increased the body weight (p < 0.05), sperm parameters (p < 0.001), indices of spermatogenesis (p < 0.001), and testis histopathology as well as decreased the blood glucose level (p < 0.001) compared to the untreated diabetic group, although it had no significant effect on testicular parameters, LH and FSH levels. Nitrate administration in the DN group also decreased miR-34b (p < 0.001) and p53 mRNA (p < 0.001) expression, and increased serum insulin and NOx levels compared to the untreated diabetic rats. CONCLUSIONS Chronic nitrate supplementation in streptozotocin-induced diabetic rats improved fertility parameters, which may be associated with increased miR-34b and decreased p53 mRNA.

Abstract
BACKGROUND Obesity-induced chronic inflammation is a key component in the pathogenesis of insulin resistance and type-2 diabetes Objective: This study aimed to evaluate the effect of swimming exercise on pancreatic expression levels of inflammatory cytokines, miR-146a and NF-кB in type-2 diabetic male rats. METHODS Twenty- eight male Wistar rats were divided into four groups: control (Con), exercise, diabetes and diabetic exercise (n = 7). Diabetes induction performed by the combination of high-fat diet (HFD, 4 weeks) and streptozotocin (35 mg/kg. ip). After induction of diabetes, the rats swam in the exercise groups for 12 weeks. Then, blood and tissue samples were collected. RESULTS Our results indicated a significant increase in expression levels of miR-146, NF-κB and inflammatory cytokines (IL-6, TNF-α, and IL-1β) while a significant decrease in pancreatic expression levels of TRAF6 and IRAK1 in diabetic group as compared to the control group. In contrast, swimming exercise resulted in a significant decrease in expression levels of miR-146a, NF-кB and inflammatory cytokines and a significant increase in expression levels of TRAF6 and IRAK1 in the exercise-diabetic group compared to the diabetic group. CONCLUSION Our results indicated a significant increase in expression levels of miR-146, NF-κB and inflammatory cytokines (IL-6, TNF-α, and IL-1β) while a significant decrease in pancreatic expression levels of TRAF6 and IRAK1 in diabetic group as compared to the control group. In contrast, swimming exercise resulted in a significant decrease in expression levels of miR-146a, NF-кB and inflammatory cytokines and a significant increase in expression levels of TRAF6 and IRAK1 in the exercise-diabetic group compared to the diabetic group.

Abstract
Objective: Susceptibility to diabetes-induced bone complication has been linked to Wnt signaling, which plays an important role in bone development and remodeling. In this study, the effect of swim training on Wnt pathway in T2DM was investigated. Materials and methods: Forty male rats were assigned to groups: control (C), diabetic (D), exercised control (E) and diabetic exercised (DE). One week after the induction of diabetes, animals were subjected to swim. At the end of training, bone gene and protein levels of SOST, RUNX2 and RANKL/OPG ratio were measured. Results: Diabetes could significantly increase bone sclerostin expression levels, while decreased RUNX2 mRNA and protein. Bone RANKL/OPG ratio was significantly lower in diabetic rats compared to control group. Swim training significantly increased this ratio in DE compared to D group. Conclusion: Swim training could partially compensate the diabetes-associated changes of Wnt pathway possibly by moderating sclerostin or blood sugar.

Abstract
OBJECTIVE The importance of swimming in bone metabolism during type 2 diabetes (T2DM) is not well known. Receptor activator of nuclear factor-kB ligand (RANKL)/ osteoprotegerin (OPG) system as a critical pathway in bone remodeling may play a role in pathogenesis of T2DM. Hence, we tested this pathway and the possible beneficial effects of swim training on T2DM. MATERIALS AND METHODS Forty male rats were assigned to groups (n = 10): control(C), diabetic (D), exercised control (E), and diabetic exercised (DE). One week after the induction of diabetes, animals were subjected to swim. At the end of training, fasting blood sugar, insulin, bone and serum OPG and RANKL levels were measured. RESULTS Diabetes significantly increased OPG and decreased RANKL mRNAs and proteins in bone and serum and swim training could reverse these changes to control. CONCLUSION Swim training could partially compensate T2DM associated changes of bone and serum OPG/RANKL in rats.

Abstract
Epidemiological and clinical studies have demonstrated a close association between obesity and asthma. The current study investigated the effect of high-fat diet on tracheal responsiveness to methacholine and insulin resistance in ovalbumin (OVA) sensitized male and female rats.
The rats were divided into eight groups (n=6 per group): female with the normal diet (F+ND), male with the normal diet (M+ND), female OVA-sensitized with the normal diet (F+SND), male OVA-sensitized with the normal diet (M+SND), female with high-fat diet (F+HFD), male with high-fat diet (M+HFD), female OVA-sensitized with high-fat diet (F+SHFD), and male OVA-sensitized with high-fat diet (M+SHFD). All rats were fed for 8 weeks with high-fat diet or standard pelts, and for another 4 weeks, they were sensitized with OVA or saline. At the end of the study, the tracheal responsiveness to methacholine, serum insulin, and blood glucose levels was measured. Also, insulin resistance indexes were determined.
OVA-sensitization and diet-induced obesity caused the curve of methacholine concentration response to shifting to the left. In addition, results indicated that the EC50 (the effective concentration of methacholine generating 50% of peak response) in F+SHFD rats was statistically lower than M+SHFD group (p<0.05). Moreover, insulin resistance was higher in the F+SHFD than the M+SHFD group (p<0.001).
These results suggest that insulin resistance and metabolic syndrome may be involved in the pathogenesis of obesity associated with OVA-sensitized rats condition, especially in female animals.

Abstract
The present study aimed to investigate the role of microRNA-146a and its adapter proteins [interleukin-1 receptor-associated kinase 1 (IRAK1) and tumor necrosis factor (TNF) receptor-associated factor 6 (TRAF6)] in the pathogenesis of ovalbumin (OVA)-sensitized rats in association with the diet-induced obesity condition. Twenty male Wistar rats were divided into four groups: control with normal diet (ND), OVA-sensitized with normal diet (S + ND), high-fat diet (HFD), and OVA-sensitized with high-fat diet (S + HFD). All the animals were fed for 8 weeks with standard pelts or high-fat diet, and were then sensitized and challenged with OVA or saline for another 4 weeks. The tracheal responsiveness to methacholine, serum protein levels, and lipid profile levels was measured by the ELISA method. Moreover, the gene expression level of microRNA-146a (miR-146a) was measured in the lung tissue of the rats using the real-time PCR method. Maximum response to methacholin increased in the S + HFD group in compared with ND, S + ND, and HFD groups (P < 0.05 to P < 0.001). Moreover, in the S + HFD group the mRNA expression levels of miRNA-146a increased in the lung tissue (P < 0.001). In addition, the protein analysis results showed that IRAK1, TRAF6, NF-kB, and IL-1β protein levels were high in the S + HFD group compared to the ND and HFD groups; however, in compared with the S + ND group, only the IL-1β protein level was higher in the S + HFD group (P < 0.05). These results suggest that a defect in the NF-kB-miR-146a negative feedback loop may be involved in the pathogenesis of obesity associated with OVA-sensitized condition. © 2018 BioFactors, 45(1):75-84, 2019.

Abstract
Non-alcoholic steatohepatitis (NASH) is an inflammatory and progressive form of non-alcoholic fatty liver disease. However, there are no FDA-approved drugs for this condition. Lipids accumulated in NASH have a direct role in the progression of this disease. Therefore, this study for the first time explored the preventive effect of trans-chalcone on NASH through the modulation of sterol regulatory element binding protein (SREBP)-1c, SREBP-2, hepatic fatty acid synthesis (FAS) enzyme, proliferator-activated receptor (PPAR)-α, and PPAR-γ2 levels, which are involved in hepatic lipid metabolism. In this study, male rats were randomly divided into three groups (n = 7): Control, received 10% tween 80; NASH, received 10% tween 80 and 10 ml/kg high-fat emulsion (high-fat diet, HFD); and NASH + TC, received 20 mg/kg trans-chalcone and 10 ml/kg HFD. All treatments were performed by once-daily oral gavage for 6 weeks. Liver and blood samples were collected and serum levels of alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), triglyceride, total cholesterol, low-density lipoprotein (LDL)-cholesterol, and high-density lipoprotein (HDL)-cholesterol, as well as hepatic levels of SREBP-1c, SREBP-2, FAS, PPAR-α, and PPAR-γ2, were measured. Moreover, hematoxylin and eosin stained tissues were used for histological analysis. In this study, treatment of HFD-fed rats with trans-chalcone significantly reduced abnormalities in liver histology, serum levels of liver injury markers, liver index, and hepatic levels of SREBP-1c, SREBP-2, FAS, and PPAR-γ2. Furthermore, trans-chalcone significantly increased hepatic PPARα levels in these rats. Therefore, it seems that trans-chalcone protects the liver of HFD-fed rats against NASH development through reduction of SREBP-1c/ FAS- and PPAR-γ2-related lipogenesis, attenuation of SREBP-2-related cholesterol synthesis, and elevation of PPARα-related fatty acid oxidation.

Abstract
AIMS As nitric oxide (NO) production is essential for insulin signaling, glucose uptake, endothelial function, and regulation of apoptosis, the loss of bioavailable NO may be a mechanism underlying the development of diabetes complication. Dietary nitrate acts as a substrate for NO generation, thus serving as a physiological source of NO. This study evaluated the therapeutic effects of nitrate supplementation on the apoptosis-induced testicular disorders in diabetic rats. MAIN METHODS Fifty male Wistar rats were divided into five groups; control, control with 100 mg/L nitrate in distilled drinking water, diabetes, diabetes treated with 2-4 U/day NPH insulin, diabetes treated with 100 mg/L nitrate in distilled drinking water. After 8 weeks, blood samples, testis, and epididymis were collected to assess the apoptosis process and the stereology of testis tissue, sperm motility, morphology and DNA fragmentation, and also mRNA expression of miR-449a, p53, Pdcd4, and Pacs2 mRNA, as well as serum glucose, insulin, and NOx levels were investigated. KEY FINDINGS The results of this study indicated that nitrate treatment ameliorated the sperm parameters, testicular morphometrical and stereological alterations, reduced blood glucose, the number of TUNEL positive cells and tubules, and testicular expressions of p53, Pdcd4, and Pacs2 mRNA as well as increased body weight, serum insulin and NOx levels, and testicular expression of miR-449a in streptozotocin-induced diabetic rats. SIGNIFICANCE Our in vivo evidence revealed that nitrate treatment may has a favorable effect as an exogenous NO donor on experimental diabetic testicular damages in which NO bioavailability is impaired.

Abstract
Insulin resistance and inflammation are strongly linked to non-alcoholic fatty liver disease (NAFLD) as a feature of the metabolic syndrome. Furthermore, the role of dysregulation of miR-34a, miR-451, and miR-33a in pathogenesis and progression of NAFLD has been identified. trans-Chalcone is a simple chalcone with anti-diabetic and anti-inflammatory activities. However, to the best of our knowledge, miRNA-dependent mechanisms of these protective effects under pathologic conditions are not understood. Thus, this study, for the first time, aimed to evaluate the effects of trans-Chalcone on miR-34a, miR-451, and miR-33a signaling pathways in the liver of high-fat (HF) emulsion-fed rats. To this aim, twenty-one rats were randomly and equally divided into three groups: control, which was gavaged with 10% tween 80; HF, which was gavaged with HF emulsion and 10% tween 80; and HF + trans-Chalcone (HF + TC), which was gavaged with HF emulsion and trans-Chalcone. Then, circulating levels of glucose and insulin were measured and used for the calculation of HOMA-IR. Hepatic expression levels of miR-34a, miR-451, miR-33a, SIRT1, and ABCA1 and also protein levels of ABCA1 and IL-8 were assayed. In this study, trans-chalcone increased hepatic cholesterol efflux and prevented insulin resistance and liver inflammation in HF emulsion-fed rats. These protective effects were modulated through the down-regulation of miR-34a and its associated elevation of SIRT1, the up-regulation of miR-451 which was associated with a reduction in IL-8, and the inhibition of miR-33a which was related to the elevation of ABCA1 in the liver of HF emulsion-fed rats. Therefore, trans-Chalcone exerts its beneficial effects by targeting hepatic miR-34a-, miR-451-, and miR-33a-related pathways.

Abstract
OBJECTIVE Diabetes is associated with vascular complications and impaired angiogenesis. Since angiogenesis plays a crucial role in vascular homeostasis in ischemic heart diseases, in this study, the effect of IMOD™ on miR-503 and CDC25 expression level which are altered in impaired angiogenesis were investigated in heart tissue of diabetic rats. MATERIALS AND METHODS Forty male Wistar rats (200-250 g) were randomly classified into 4 groups: control (C), IMOD™ (I), diabetes (D), and diabetes+IMOD™ (D+I). For induction of experimental diabetes in animals, a single dose of streptozotocin (STZ; 60mg/kg) was injected intraperitoneally. After 8 weeks of treatment with IMOD™ (20 mg/kg/day), heart tissue samples were removed and used for measurement of miR-503 and CDC25 expression level as well as histological studies. RESULTS Results of this study showed that diabetes decreased heart tissue angiogenesis which was associated with increased miR-503 and reduced CDC25 expression levels (p<0.05) and IMOD™ could reduce the expression of miR-503 and increase the expression of CDC25 (p<0.05). Moreover, IMOD™ extensively induced angiogenesis in the heart tissue of diabetic group. However, IMOD™ had no significant effect on expressions of miR-503 and CDC25, or angiogenesis in healthy rats. CONCLUSION This study showed that IMOD™ is able to increase angiogenesis in the heart tissue of diabetic rats. The angiogenic effect of IMOD™ is associated with reduction of miR-503 expression and increased expression of CDC25.

Abstract
Hypoxia can lead to changes in the blood flow, nutrition and oxygenation of male germ cells and results in fertility reduction through the increase in oxidative stress. This study aims to evaluate the effect of ghrelin on testicular damage induced by hypoxia in rats. In this experimental study, 24 male rats were randomly divided into four groups: control, hypoxia, hypoxia + ghrelin and ghrelin. Animals in the control and ghrelin groups were kept in room air with 21% oxygen. The animals in the groups of hypoxia and hypoxia + ghrelin were subjected to 11% oxygen for 14 consecutive days in the hypoxia chamber. At the end of the study, the testes were removed and histological changes, as well as the apoptotic index, were investigated. Morphometrical analysis showed that hypoxia caused a significant decrease in the seminiferous tubules diameter, the germinal epithelium thickness and main Johnson's score compared to the control group (p < .05). In addition, statistical comparisons revealed a significant increase in the apoptotic index in the hypoxia group (p < .05). Administration of ghrelin + hypoxia improved the parameters mentioned above (p < .05). The results of this study indicated that ghrelin decreases the testicular damages caused by hypoxia in the rats by antioxidative activity.

Abstract
OBJECTIVE Trans-chalcone is a chalcone with hepatoprotective and anti-inflammatory effects. However, the mechanism of these positive effects, especially on miR-451 as an inflammatory regulator, is poorly understood. In this regard, this microRNA (miRNA) acts by inhibition of hepatic interleukin-8 (IL-8) production in the liver which is one of the main proinflammatory cytokines. Th is study for the first time examined the effect of trans-chalcone on miR-451/IL-8 pathway. METHODS In present study, 21 male rats were randomly divided into 3 groups (n=7 per each group): control which received solvent (NS), groups 2 (N2T) and 3 (N6T), which received transchalcone for 2 and 6 weeks, respectively. Hepatic level of miR-451 was measured by qRT-PCR. Serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) as well as hepatic level of IL-8 protein were measured. RESULTS Trans-chalcone decreased hepatic level of IL-8 protein and serum level of ALT aft er 2 weeks of treatment without significant change in hepatic miR-451. Moreover, it increased hepatic level of miR-451 and reduced hepatic IL-8 as well as AST and ALT aft er 6 weeks. CONCLUSION Based on the results of present study, miR-451/IL-8 pathway is a possible mechanism for hepatoprotective action of trans-chalcone in long-term.

Abstract
Thyroid hormone deficiency during fetal life (fetal hypothyroidism) causes intrauterine growth restriction (IUGR). Fetal hypothyroidism (FH) could attenuate normal cardiac functions in the later life of the offspring rats. The aim of this study was to evaluate the contribution of myomiR network and its target gene expression in cardiac dysfunction in fetal hypothyroid rats. Six Pregnant female rats were divided into two groups: Control consumed tap water, and the hypothyroid group received water containing 0.025% 6-propyl-2-thiouracil during gestation. Hearts from male offspring rats in adulthood (month 3) were tested with Langendorff apparatus for measuring hemodynamic parameters. Expressions of miR-208a, -208b, and -499 and its target genes including thyroid hormone receptor 1 (Thrap1), sex-determining region Y-box 6 (Sox6), and purine-rich element-binding protein β (Purβ) were measured by qPCR. FH rats had lower LVDP (%20), +dp/dt (%26), -dp/dt (%20), and heart rate (%21) than controls. FH rats at month 3 had a higher expression of β-MHC (190%), Myh7b (298%), and lower expression of α-MHC (36%) genes in comparison with controls. FH rats at month 3 had a higher expression of miR-499 (520%) and miR-208b (439%) and had lower expression of miR-208a (74%), Thrap1 (47%), Sox6 (49%), and Purβ (45%) compared with controls. Our results showed that thyroid hormone deficiency during fetal life changes the pattern of gene expression of myomiR network and its target genes in fetal heart, which, in turn, resulted in increased β-MHC expression and associated cardiac dysfunction in adulthood.

Abstract
Objectives: Inflammation plays a critical role in the progression of diabetic complications such as neurological disorders. Previous reports have indicated the memory-improving effect of troxerutin, in rat hippocampus, but the underlying mechanisms are unclear. Hence, we have investigated the effect of troxerutin pretreatment on gene expressions of inflammation-related microRNAs (miRs), miR-146a and miR-155, and nuclear factor-kappa B (NF-κB) signaling pathway in the hippocampus of healthy and diabetic rats. Materials and Methods: Wistar rats were randomly divided into four groups (control, control + troxerutin, diabetic, and diabetic + troxerutin). Diabetes was induced by a single i.p. injection of streptozotocin (50 mg/kg). Troxerutin (150 mg/kg) was orally administered in animals for 1 month. After 10 weeks of diabetes, animals were anesthetized and decapitated for the isolation of hippocampus. The expression of miR-146a and miR-155 and the messenger RNA (mRNA) expressions of NF-κB, interleukin-1 receptor-associated kinase-1 (IRAK-1), and tumor necrosis factor receptor-associated factor-6 (TRAF-6) were analyzed by real-time polymerase chain reaction. Results: Diabetes significantly increased hippocampal mRNA levels of NF-κB, IRAK-1, and TRAF-6 compared with nondiabetic rats (P < 0.05); however, pretreatment with troxerutin decreased them in both diabetic and nondiabetic animals, independent of its glycemic effect (P < 0.05). The expression levels of miR-146a and miR-155 were decreased in diabetic group as compared to the control (P < 0.01). Conclusion: These findings showed that troxerutin could inhibit the inflammatory NF-κB pathway in the hippocampus of diabetic rats, which may be due to the negative feedback loop regulated by miR-146a.

Abstract
Peripheral nerve injuries with a poor prognosis are common. Evening primrose oil (EPO) has beneficial biological effects and immunomodulatory properties. Since electrical activity plays a major role in neural regeneration, the present study investigated the effects of electrical stimulation (ES), combined with evening primrose oil (EPO), on sciatic nerve function after a crush injury in rats. In anesthetized rats, the sciatic nerve was crushed using small haemostatic forceps followed by ES and/or EPO treatment for 4 weeks. Functional recovery of the sciatic nerve was assessed using the sciatic functional index. Histopathological changes of gastrocnemius muscle atrophy were investigated by light microscopy. Electrophysiological changes were assessed by the nerve conduction velocity of sciatic nerves. Immunohistochemistry was used to determine the remyelination of the sciatic nerve following the interventions. EPO + ES, EPO, and ES obviously improved sciatic nerve function assessed by the sciatic functional index and nerve conduction velocity of the sciatic nerve at 28 days after operation. Expression of the peripheral nerve remyelination marker, protein zero (P0), was increased in the treatment groups at 28 days after operation. Muscle atrophy severity was decreased significantly while the nerve conduction velocity was increased significantly in rats with sciatic nerve injury in the injury + EPO + ES group than in the EPO or ES group. Totally speaking, the combined use of EPO and ES may produce an improving effect on the function of sciatic nerves injured by a crush. The increased expression of P0 may have contributed to improving the functional effects of combination therapy with EPO and ES as well as the electrophysiological and histopathological features of the injured peripheral nerve.

Abstract
OBJECTIVE To investigate the effects of diet-induced obesity on the expression of nuclear factor-κB (NF-κB) and visfatin messenger RNA in male Wistar rats' tracheae after sensitization with ovalbumin (OVA). MATERIALS AND METHODS Twenty male Wistar rats were divided into 4 groups (n = 5 for each group), which included a control group fed a normal diet (ND) and groups fed normal diet, OVA-sensitized (S+ND); high-fat diet (HFD) only (diet-induced obesity); and high-fat diet, OVA-sensitized (S+HFD). All animals were fed for 8 weeks with standard chow or a high-fat diet, and then were sensitized and challenged with OVA or saline for another 4 weeks as per the above groups. The rats were anesthetized, after which the necks were exposed and the tracheae isolated and examined for expression levels of NF-κB and visfatin mRNA with the real-time polymerase chain reaction method. Data were compared between the different groups using one-way analysis of variance. RESULTS The expression level of NF-κB mRNA in the S+HFD group was 2.67, which was statistically higher than the levels in the ND (0.96; p = 0.001), S+ND (1.86; p = 0.05), and HFD (1.26; p = 0.001) groups. Also, the visfatin mRNA expression level in the S+HFD group was 4.21, which was higher than the levels in the ND (0.92), S+ND (1.79), and HFD (2.20) (p = 0.001) groups. CONCLUSION In this study, the expression levels of NF-κB and visfatin were markedly higher in the S+HFD group in comparison to the other groups. These findings indicate that alternative signaling pathways might be activated in diet-induced obesity associated with the OVA-sensitized animal model and could be responsible for possible altered sensitization phenotype.

Abstract
Background Impaired angiogenesis in cardiac tissue is a major complication of diabetes.
Protein kinase B (AKT) and extracellular signal regulated kinase (ERK)
signaling pathways play important role during capillary-like network
formation in angiogenesis process. Objectives To determine the effects of testosterone and voluntary exercise on levels of
vascularity, phosphorylated Akt (P- AKT) and phosphorylated ERK (P-ERK) in
heart tissue of diabetic and castrated diabetic rats. Methods Type I diabetes was induced by i.p injection of 50 mg/kg of streptozotocin in
animals. After 42 days of treatment with testosterone (2mg/kg/day) or
voluntary exercise alone or in combination, heart tissue samples were
collected and used for histological evaluation and determination of P-AKT
and P-ERK levels by ELISA method. Results Our results showed that either testosterone or exercise increased
capillarity, P-AKT, and P-ERK levels in the heart of diabetic rats.
Treatment of diabetic rats with testosterone and exercise had a synergistic
effect on capillarity, P-AKT, and P-ERK levels in heart. Furthermore, in the
castrated diabetes group, capillarity, P-AKT, and P-ERK levels significantly
decreased in the heart, whereas either testosterone treatment or exercise
training reversed these effects. Also, simultaneous treatment of castrated
diabetic rats with testosterone and exercise had an additive effect on P-AKT
and P-ERK levels. Conclusion Our findings suggest that testosterone and exercise alone or together can
increase angiogenesis in the heart of diabetic and castrated diabetic rats.
The proangiogenesis effects of testosterone and exercise are associated with
the enhanced activation of AKT and ERK1/2 in heart tissue.

Abstract
Background The arterial ductus is a major communicative pathway which is naturally patent in the fetus, connecting the body of the major pulmonary artery to the descending aorta. Although usually closing on its own, the patent ductus arteriosus (PDA) may remain open in the second postnatal week due to a lack of prompt diagnosis in the initial days of life or an absence of prompt treatment. Objectives To prevent the untoward sequelae of patency of the ductus arteriosus, and to avoid invasive surgery at higher ages, the researchers in the present study embarked on determining the effects of oral ibuprofen during the second postnatal week on newborns with patent ductus arteriosus. Patients and Methods In this study, 70 neonates aged eight to 14 days, presenting at Khatam-al-Anbia clinic and the NICU ward of Shahid Sadoughi hospital in Yazd, Iran, who were diagnosed with PDA through auscultation of heart murmurs and echocardiography, were randomly assigned to two groups. The experimental group received oral ibuprofen of 10 mg/kg in day 1, 5 mg/kg in day 2, and 5 mg/kg in day 3 administered by their parents. The control group did not receive any drug. Parents were informed of the potential drug complications and side effects and asked to report them to the researchers if any occurred. Results After intervention, the patent ductus arteriosus was closed in 62.9% of the neonates in the experimental group (35 newborns) who received oral ibuprofen, while it was closed in 54.3% of the control neonates (35 newborns) who did not receive any drug (P = 0.628). No complications were observed in either of the neonatal groups. Conclusions Our findings showed that administration of oral ibuprofen had no significant effect on the medicinal closure of PDA in full-term neonates during the second postnatal week.

Abstract
BACKGROUND Thyroid hormone deficiency during fetal life could affect the cardiac function in later life. The mechanism underlying this action in fetal hypothyroidism (FH) in rats has not been elucidated thus far. OBJECTIVE The aim of this study is to evaluation the effect of FH on cardiac function in male rats and to determine the contribution of α-myosin heavy chain (MHC) and β-MHC isoforms. METHODS Six pregnant female rats were randomly divided into two groups: The hypothyroid group received water containing 6-propyl-2-thiouracil during gestation and the controls consumed tap water. The offspring of the rats were tested in adulthood. Hearts from the FH and control rats were isolated and perfused with langendroff setup for measuring hemodynamic parameters; also, the heart mRNA expressions of α- MHC and β-MHC were measured by qPCR. RESULTS Baseline LVDP (74.0 ± 3.1 vs. 92.5 ± 3.2 mmHg, p < 0.05) and heart rate (217 ± 11 vs. 273 ± 6 beat/min, p < 0.05) were lower in the FH rats than controls. Also, these results showed the same significance in ±dp/dt. In the FH rats, β-MHC expression was higher (201%) and α- MHC expression was lower (47%) than control. CONCLUSION Thyroid hormone deficiency during fetal life could attenuate normal cardiac functions in adult rats, an effect at least in part due to the increased expression of β-MHC to α- MHC ratio in the heart.

Abstract
Epidemiological and clinical studies indicate a close relationship between obesity and asthma. Here, we determined the impact of diet-induced obesity on the expression levels of IL-1β, IRAK-1 and TRAF-6 mRNA as well as IL-1β protein level and pathological changes in male Wistar rat's lung after sensitization with ovalbumin (OVA). Twenty male Wistar rats divided into four groups, control with normal diet (C+ND), OVA-sensitized with normal diet (S+ND), control with high-fat diet (C+HFD), and OVA-sensitized with high-fat diet (S+HFD). All rats fed for 12 weeks with standard pellets or high-fat diet while sensitization and challenging with OVA or saline were done for groups in the last month. In the end of intervention, lung was isolated and tested for the expression levels of IL-1β, IRAK-1 and TRAF-6 mRNA with real time-PCR method, and pathological changes were determined. Diet-induced obesity groups showed increased weight, obesity indexes and lipid profiles The expression levels of IL-1β mRNA in OVA-sensitization groups (S+ND and S+HFD) showed a significant increase compared with other groups. Also in S+HFD group, expression level of IRAK-1 and TRAF-6 mRNA were markedly higher than other groups (p<0.001). The pathological changes were marked in sensitized groups compared to non-sensitized groups; with marked increase in obese sensitized rat. The results showed that high fat diet caused overexpression of IL-1β, IRAK-1 and TRAF-6 mRNA as well as IL-1β protein in an experimental model of asthma. Our results suggest that obese-asthmatic conditions may lead to the local production and activation of pro-inflammatory agents.

Abstract
OBJECTIVES Human and animal studies have shown a close relationship between obesity and asthma severity. Here, we examined the effects of diet-induced obesity (DIO) on the expression levels of IL-1β, IRAK-1 and TRAF-6 mRNA in male Wistar rats tracheal after sensitization with ovalbumin (OVA). MATERIALS AND METHODS Twenty male Wistar rats divided to four groups, included, control group with normal diet (C+ND), OVA-sensitized group with normal diet (S+ND), control group with high-fat diet (C+HFD), and OVA-sensitized group with high-fat diet (S+HFD). All animals fed for 8 weeks with standard pelts or high-fat diet, and then were sensitized and challenged with OVA or saline for another 4 weeks with designed regimens. At the end of study, trachea isolated and examined for expression levels of IL-1β, IRAK-1 and TRAF-6 mRNA with RT-PCR method. RESULTS Diet-induced obesity groups developed increased weight, obesity indexes and lipid profiles (P<0.05 to P<0.001). The expression levels of IL-1β mRNA in OVA-sensitization groups (S+ND and S+HFD) showed a significantly increased when compared with control group. Also in S+HFD group, expression level of TRAF-6 mRNA was higher than other groups (P<0.001). IRAK-1 expression level was high in S+HFD compared with control group.IL-1β and TRAF-6 mRNA correlated positively with obesity indexes. CONCLUSION The results showed that DIO causes overexpression of IL-1β, IRAK-1 and TRAF-6 mRNA in an experimental model of asthma. Our results suggested that in obese-asthmatic conditions locally production and activation of pro-inflammatory agents can be increased. These findings showed that possible mechanism for obesity-asthma relationships.
