Abstract
Background: Laryngeal carcinoma induce immune system suppression in tumour micro environments with unknown mechanism. Toll like receptors (TLRs) are important molecules which play a critical role in the management and induction of immune responses. In this regard, the importance and the role of TLR 2, 4 and 9 have not been studied together in laryngeal cancer. The present study aims to evaluate the expression level of TLR2, TLR4 and TLR9 in patients with laryngeal carcinoma.
Materials and Methods: 89 tumour samples and 35 tumour-free tissues were obtained from laryngeal carcinoma male patients and the expression level of TLR2, TLR4 and TLR9 was analysed using Real-time PCR method.
Results: The expression level of TLR2 was increased as the result of increasing lymph node involvement, pretumoral involvement and regional metastasis. Also, the TLR4 gene expression levels were increased 1.5 fold in patients with lymph node involvement. The expression Level of TLR9 was increased by increasing stage and primary tumour involvement. The expression pattern of TLR2 and TLR4 in tumour and tumour-free tissues was the same, while TLR9 gene expressions show higher level in tumour tissues than its normal tissue. None of our findings were statistical significant.
Conclusion: we have shown that the expression status of TLR2, TLR4 and TLR9 in patients with laryngeal cancer was correlated with their clinicopathologic features. Additionally, the expression level of TLRs in cancerous and non-cancerous tissues shows no significant changes.

Abstract
Background: The aim of this study was to investigate the effect of resistance training with different intensities on serum myostatin and follistatin levels in sedentary young women.
Materials and Methods: In this practical and semi experimental study, 24 sedentary young women with range of 20-30 years and BMI 22-25 kg/m2 were selected by convenience sampling. Then, the volunteers were randomly assigned into two groups, [resistance training group with low intensity (40-60% of one repetition maximum) and high intensity (70-90% of one repetition maximum)]. The training protocols included: 8 weeks, 3 times a week. Blood samples (5cc) were obtained at baseline and 48 hours after at the end of the study; Also Serum levels of myostatin and follistatin were measured by ELISA methods. Data were analyzed using analysis of variance of repeated measures test by SPSS at the significant level (p<0.05).
Results: There was a significant increase in the levels of follistatin and follistatin to myostatin ratio in high intensity group (p≤0.05). Also there was a significant decrease in the levels of myostatin in high intensity group (p≤0.05); however, there was no significant change in the levels of follistatin, myostatin and follistatin to myostatin ratio in low intensity group (p≥0.05). Also there was no significant change in these variables in high intensity group compared to low intensity group (p≥0.05).
Conclusion: It’s seems that the activation of important myogenic and myostatic factors in sedentary young women need to do high intensity resistance training.

Abstract
Background: Parvovirus 4 (PARV4) was first discovered in 2005, in a hepatitis B virus–infected injecting drug user (IDU). To date, the best evidence about PARV4 transmission is parenteral roots and comes from IDU individuals. It seems that the prevalence of the virus in the normal population is very low. In this study, we investigated the prevalence of PARV4 virus among patients with chronic HCV infection compared with healthy controls and related risk factors among these groups.
Materials and Methods: A total of 206 patients, including 103 patients with chronic HCV infection and 103 healthy controls, were studied by use of nested-PCR and also real-time PCR techniques.
Results: AST enzyme levels with a mean of 40.45+34.84 and 18.58+5.9 in patients and healthy group respectively and the amount of enzyme ALT among patients with a mean of 40.45+35.75 and 21.50+11.35 in patients and healthy group respectively, were reported. Finally, after screening all DNA samples from patients and controls, we discovered that none of these people are infected with the PARV4 virus.
Conclusion: This study is the first to investigate the occurrence of PARV4 among HCV patients in Iran. The results show that, the virus is not important in Iranian population, even in patients with blood born infections such as HCV and further studies in other areas and various groups are required.

Abstract
Background: The aim of this study was to investigate the response of the most important angiogenic and angiostatic factors to a session activity before and after a period of L-Arginine supplementation in active men.
Materials and Methods: In this practical and semi experimental study, 22 active men were selected by convenience sampling method and they were randomly assigned into supplement (n=11) and placebo (n=11) groups. Baseline levels of VEGF and endostatin were measured, then subjects participated an exhaustive treadmill protocol in pre-test and post-test. Immediately and two hours after the protocol, 3 cc blood samples were prepared. The subjects used daily 0.1 g.kg-1 respectively taking l-arginine and placebo for 14 days. The results were analyzed at the significant level (p<0.05).
Results: Immediately after exercise, the levels of VEGF and VEGF to endostatin ratio were significantly decreased in both groups compared to baseline (p≤0.05), and two hours later this change were lower than the baseline value (p≤0.05). The levels of endostatin immediately after exercise were significantly increased in both groups compared to baseline (p≤0.05) and two hours later this change were lower than the baseline value (p≤0.05). Before and after L-Arginine supplementation, the levels, of VEGF and VEGF to endostatin ratio immediately after exercise were not significant(p≥0.05). while this change in the supplementation group were significantly increased two hours after exercise (p≤0.05). There was no significant change in the levels of endostatin between two groups immediately after exercise (p≥0.05); however, these changes were significantly decreased two hours after exercise (p≤0.05).
Conclusion: It seems that short-term L-arginine supplementation probably stimulate angiogenesis factors in response to exercise in active men.

Abstract
Background: Neuronal damage following seizures and epilepsy is one of the main causes of disabilities and mortality worldwide. In recent years, preconditioning has been introduced as a novel strategy for the prevention of brain damage. Preconditioning is a phenomenon in which a minor noxious stimulus protects from a subsequent more severe insult. The aim of present study was to examine the effect of ethanol (Eth) preconditioning on pentylenetetrazole (PTZ)-induced impairment memory in the inhibitory avoidance model.
Material and Methods: This study was carried out on 45 adult male Wistar rats (180-200 g). Animals were assigned into five groups: Control, Eth 0.25, Eth 0.5, PTZ and Eth (0.5) +PTZ (n=9, for all groups). Eth-preconditioning was induced 6 days before the injection of PTZ. The animals were tested in a single trial step-through inhibitory test in two sessions (train and test). Then locomotor activity of rats was recorded in the open-field apparatus and NR1 mRNA expression in the hippocampus was measured by real-time PCR technique.
Results: One-way ANOVA revealed that the Ethanol preconditioning did not impair inhibitory memory. Further, post-test analyses showed that Ethanol preconditioning significantly prevented from PTZ-induced memory impairment, and increased NR1 subunit mRNA expression in PTZ-induced memory impairment group. In addition, one-way ANOVA for the locomotor activity showed no significant difference between the groups.
Conclusion: Our results showed that a pre-conditioning treatment with Ethanol
(0.5g/kg/day), 6 days before PTZ-induced memory impairment may provide a kind of neuroprotection in rats.

Abstract
Background: The rhizome of Iris songarica Scherenk has been prescribed as anodyne in Persian traditional medicine system. However, its effects have never been investigated experimentally. Thus, the present study was designed to evaluate the antinociceptive and anti-inflammatory effects of alcoholic extract of Iris songarica Scherenk rhizome in mice.
Material and Methods: In this experimental study, adult male balb/c mice were used. 40 animals were allocated into five equal groups (control, morphine 5mg/kg, the extracts at doses of 100, 200 and 300 mg.kg) and tested for antinociceptive evaluation via using hot-plate in 30,60 and 120 minutes after the investigations. Also, the other 36 mice were divided into six equal groups (no-inflammation control, inflammation model, dexamethasone 4 mg/kg and the extracts at doses of 100, 200 and 300 mg.kg) and evaluated for anti-inflammatory activity in xylene induced inflammation model. All the investigations were done via intraperitoneal injection. Data were analyzed using one-way ANOVA or Kruskal-Wallis tests in SPSS.
Results: Compared to the control group, the extract at the all doses could increase latency time in hot plate test at 30, 60 and 120 minutes after investigation (p<0.05).This potential was comparable to morphine in the high doses or long time. In addition, the extracts at the all doses exhibited high anti-inflammatory activity which was comparable to dexamethasone (p<0.001).
Conclusion: The results of present study clearly showed that Iris songarica Scherenk rhizome has antinociceptive and anti-inflammatory activities in mice.

Abstract
Abstract
Background: High morbidity and limited therapies of hepatic fibro genesis are important factor for better understanding the molecular mechanisms of the disease. Advances in the understanding of the molecular behavior of hepatic stellate cells (HSC) allow the progress of a field dedicated to anti-fibrotic therapy. Melanoma differentiation associated gene-7 (IL-24/mda-7) as a gene induced during terminal differentiation in human melanoma cells, but the inflammatory response of cells to IL-24/mda-7 is not entirely cleared.
Materias and Methods: LX-2 cells (a human hepatic stellate cell) were treated by leptin (positive control), media (control negative), or were transfected by empty plasmid and pcDNA3.1/mda-7. The inflammatory state was evaluated through measuring the mRNA expression level of inflammatory molecule, IL-1β. The role of IL-24/mda-7 modulation on inflammatory response was assayed using SOCS1 and SOCS3 gene expressions.
Results: The expression levels of IL-1β, SOCS1 and SOCS3 were compared in LX-2 cell line groups. The expression of the IL-1β in the transfected cells was higher than the control cell, but it was not significant. The results indicated that the expressions of SOCS1 and SOCS3 were up-regulated following pcDNA 3.1/mda-7 transfection into LX-2 cells compared to control plasmids (p=0.0179, p=0.0428).
Conclusion: The endogenous IL-24/mda-7 exhibited a significant modulatory effect on stellate cells. Therefore, IL-24/mda-7 and relevant signaling pathways could be employed as a target for fibrosis treatment.

Abstract
Background and Aim: Ziehl Nelson staining, fluorescent and also culture are the standard methods for the diagnosis of tuberculosis. In this study, the performance of conventional cultivation methods was compared with Flash PCR.
Materials and Methods: A total of 56 sputum samples from patients with suspected tuberculosis in Tuberculosis Center of Arak city were collected and Ziehl–Neelsen and culture in Löwenstein–Jensen medium were accomplished. Moreover, DNA from all of the 56 sputum samples was extracted by Chelex100 method. Molecular evaluation was accomplished by Flash PCR kit containing probes and primers for gene amplification IS6110. Positive and negative controls together with samples were used in a MTC410 apparatus for amplification. FD-12 apparatus was used to evaluate the results. In addition, electrophoresis on agarose was used for confirmation of the results.
Findings: From 56 sputum samples of suspected TB patients, 20 samples were positive and 36 samples were negative on microscopic evaluation and culture methods. FLASH-PCR molecular analysis showed that all of 20 positive samples were positive in molecular methods, too. On the other hand, three of sputum samples that were negative by culture and staining were positive in FLASH-PCR method. One of these 3 patients, received Isoniazid, pyrazinamide and ethambutol antibiotic by responsible medicine. All results were confirmed using conventional electrophoresis.
Conclusion: In some negative samples, possibly because of the small number of bacteria in sample or a defect in the sampling, the Flash PCR may due good advantages. Therefore, due to the low cost, this method is recommended for routine use.

Abstract
Background and Aim: Background and Aim: Photodynamic therapy is a minimally invasive approach to cancer, which is used to combine non-toxic photosensitizer and visible light to produce reactive oxygen species and destroy tumors. This study aimed to investigate the cytotoxicity effect of Graphene Oxide (GO)as an organic matter with many oxygen groups on photodynamic on destroying cancer cells.
Materials and Methods: This study was performed on breast cancer cells (MCF-7) in vitro. The study groups included the first group of drug with different concentrations of graphene oxide (333.3, 285.7, 230.7, 166.6, 90.9,
47.6 µg/ml), the second group co-drug and laser light irradiation and the control group consisted of cells treated only with laser irradiation and the control group was treated with no treatment. Cells were exposed to visible laser irradiation (405 nm) at 0.1 W / cm2. Cell viability was determined by MTT assay.
Ethical Considerations: This study with research ethics code SBU/S.1397.46A has been approved by research ethics committee at Shahid Behesht University of Tehran, Iran.
Findings: The results of in vitro experiments showed that the dark toxicity of graphene oxide at concentrations of less than the 90.9 μg / ml concentration had no significant effect on cancer cells. Also, laser light alone don’t has toxic effect on cells. But graphene oxide-mediated dynamic light therapy has reduced the bioavailability of cancer cells on average by 21% over dark toxicity. Results are presented as mean of three independent replications, standard error, and p< 0.05 was considered significant.
Conclusion: In this study, graphene oxide is fully biodegradable at concentrations below a certain value, but with increasing concentration, the toxicity effect increases. With exposure to light and graphene oxide, viability decreses that it is more effective for in vivio studies.

Abstract
Introduction: Depression is an injury to the central nervous system that is caused by several factors that affect a large number of people around the world. Emotion regulation refers to the processes by which we influence what emotions we experience, when we experience them, and how we express them. The aim of this study was to investigate the role of emotion regulation in predicting depressive symptoms in students of Kermanshah University of Medical Sciences.
Methods: The present study is a descriptive correlational study. Participants were all students of the School of Nursing and Midwifery of Kermanshah University of Medical Sciences during 2020-2021. Three hundred and five participants were selected by available sampling method and randomly. Informed consent forms got from the participants, then they completed the Beck Depression Inventory - Second Edition (BDI-II) and the Cognitive Emotion Regulation Scale (CERQ-18). This research was reviewed in the ethics committee of Kermanshah University of Medical Sciences and approved with the ID IR.KUMS.REC.1400.623.
Results: In this study, the study population was 305 people, 9 of whom were excluded from statistical analysis due to incomplete answers. Total mean age was 50.08 ± 191.30 Of these, 198 (66.9%) were female and 98 (33.1%) were male. Self-blame strategies (β = 0.31, P≤0.001), positive reassessment (β = -0.26, P≤0.001), catastrophic (β = 0.26, P≤0.001), numerical importance (β = -0.12, P≤ 0.001) and positive refocus (β = -0.10, P≤0.001) in five steps predict 40% of the variance of depression. Inconsistent strategies such as self-blame and catastrophe directly and positive reassessment, insignificance and positive refocus inversely predict depression. Mahalanobis distance was used to investigate multivariate throw values. Statistical assumptions were tested by performing an initial regression analysis and evaluating the scatter plot of residues. After confirming the regression assumptions, the data were analyzed using Pearson correlation and stepwise regression. The findings of our study showed that there is a significant direct relationship between self-blame and catastrophic thinking as maladaptive strategies of cognitive emotion regulation with depression. Also in our study among adaptive emotion regulation strategies; Positive refocusing, positive reassessment, and a small number had a significant negative correlation with depression.
Conclusions: The results of our study showed that emotion regulation strategies play an important role in predicting the occurrence of depression. Therefore, it is necessary for health policy makers to strengthen adaptive emotion regulation strategies in designing and modifying interventions related to depression.

Abstract
Introduction: Today, with the increase in population, the per capita production of waste materials and the subsequent threat and destruction of the environment is an increasing process, and waste management by the people of a society can play an essential role in reducing this problem. Therefore, the aim of this study was determine of predicting the waste management behaviors of households in Arak city in 2022.
Methods: This is a cross-sectional and analytical study that was carried out on 600 mothers of households in Arak city, who were selected by multi-stage sampling. The data collection tool was a valid and reliable researcher-made questionnaire that included demographic characteristics, knowledge, attitude and behavior of households in the field of waste management. Data were analyzed using SPSS software and t-test, chi-square and regression tests. This study was approved by the research ethics committee of Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1401.040).
Results: The average age of the studied was 39±11 years and the number of family members was 3.6. In terms of type of housing, most of them lived in apartments (44%) and a smaller number lived in complexes (14%). 65 percent of the people had not received the training on the waste separation plan from the source, and among the effective training methods, the majority (38 percent) of the people had overestimated the effectiveness of the training through the Internet. The mean and standard deviation of knowledge was 66±19, attitude was 84±11 and performance was 73±18. The majority of the people studied had a good level of awareness and attitude. The regression analysis model showed that the greatest impact on the waste management behavior of the samples was the age of the people, their knowledge and attitude, which predicted a total of 33% of the waste management behavior.
Conclusions: Considering the favorable state of awareness and attitude of households in Arak city, it seems that for better waste management, other environmental factors should be emphasized, including sources of waste production at the source. Also, based on the prediction model, it is still important to inform and change the attitude of households in Arak city for better performance at younger ages.

Abstract
Introduction: Nowadays, the use of artificial intelligence and machine learning has impacted all fields of study. Utilizing these methods for identifying individuals' emotions through integrating audio, text, and image data has shown higher accuracy than conventional methods, presenting various applications for psychologists and human-machine interaction. Identifying human emotions and individuals' reactions is crucial in psychology and psychotherapy. Emotional identification has traditionally been conducted individually and by analyzing facial expressions, speech patterns, or handwritten responses to stimuli and events. However, depending on the subject's conditions or the analyst's circumstances, this approach may lack the required accuracy. This paper aimed to achieve high-precision emotional recognition from audio, text, and image data using artificial intelligence and machine learning methods.
Methods: This research employs a correlation-based approach between emotions and input data, utilizing machine learning methods and regression analysis to predict a criterion variable based on multiple predictor variables (the emotional category as the criterion variable and the features, audio, image, and text variables as predictors). The statistical population of this study is the IEMOCAP dataset, and the data type of this research is a mixed quantitative-qualitative approach.
Results: The results indicated that combining audio, image, and text data for multi-modal emotional recognition significantly outperformed the recognition of emotions from each data alone, exhibiting a precision of 82.9% in the baseline dataset.
Conclusions: The results demonstrate a considerably acceptable precision in identifying human emotions through audio integration, text, and image data compared to individual data when using machine learning and artificial intelligence methods.

Abstract
Introduction: The study discusses the impact of thiamine on the kidney tissue of rats that have been exposed to copper oxide nanoparticles. The research examined how thiamine correlates with the level of kidney damage caused by the intrusion of nanoparticles.
Methods: In this experimental study, forty male Wistar rats were randomly divided into four groups (10 rats per group). Two groups of rats were used as the control group (I) and the thiamine group (II). Rats of group III were administered an intraperitoneal injection of 25 mg/kg body weight of copper oxide nanoparticles for 14 days. Rats in group IV received the same dose of copper oxide nanoparticles along with thiamine (30 mg/kg body weight).
Results: The histopathological findings showed disruption of the arrangement of convoluted tubules and their disintegration and widening of the tubular lumen, cell separation and tubular necrosis in the majority of the renal tubules in-group III. In the group treated with copper oxide nanoparticles along with thiamine (IV), the pathological changes were slight and the majority of the tubules had retained normal structure. Statistically significant differences in the levels of some serum biochemical parameters (catalase, superoxide dismutase, TBARS, and TAC) were observed in groups III and IV on day 14 when compared to the control group.
Conclusions: This study demonstrated that thiamine can be utilized as an effective compound to reduce the damage caused by nanoparticles to kidney tissue and may lead to significant improvement in the health of kidney tissue in individuals suffering from damage caused by these nanoparticles.
