Background: After cardiovascular diseases, cancer is the main cause of death in the United States, and its prevalence is continually increasing. Ovarian cancer is a fetal and common cancer among women and is the eighth common cancer in Iran. Colorectal cancer is known as the second and fourth common cancer in Iranian women and men, respectively. Arazyme is a metalloprotease with strong antitumor effects on tumor cells. Objectives: This study aimed at studying the effect of metalloprotease arazyme in vitro on the expression of MMP2 and MMP9 genes, causing metastasis in ovarian and colon cancer. Methods: Bacterial strains and cell lines, the construction of an expression vector, and preparation of recombinant protein were done. Then, they were evaluated by Western blot, cell culture, cell viability assay, and reverse transcriptase-polymerase chain reaction. Results: The effects of arazyme on ovarian and colon cell lines were assessed by the MTT assay showing that the viability of cancer cells treated with arazyme decreased significantly in comparison with control cells. Also, RT-PCR showed that the expression of MMP2 and MMP9 genes decreased after treatment with arazyme, which was significant when compared to the results of pre-treatment. Conclusions: In this study, the results showed that the use of arazyme protein as a bacterial anti-protease can play a significant role in reducing the expression of metastatic genes. According to numerous studies on the role of bacterial proteases in the process of metastasis in recent years, this method can be considered as a therapeutic approach in reducing the metastatic process.

Background: Having a proper sexual function is one of the most important factors in improving marital life quality and family relationships in married people. There are a few appropriate interventions for developing the quality of sexuality in the life of married women in Iran. Objectives: Thus, this study aimed to determine the effectiveness of sexual skills training with an eclectic approach in sexual function in Iranian women. Methods: This study was a randomized single-blinded clinical trial conducted from April to September 2015 on 30 women referring to counseling centers of Yazd selected with the purposeful sampling method. Participants were randomly assigned to experimental or control groups of 15. The experimental group received sexual skills training in nine sessions of 90 min (two sessions per week) but the control group remained on the waiting list. The data were collected before the intervention and five weeks afterward using a demographic form and Female Sexual Function index (FSFI-19). We used SPSS-21 to analyze data by Kolmogorov-Smirnov (K-S) test, chi-square test, t-test, and analysis of covariance (ANCOVA) at the P = 0.05 level. Results: The results showed that sexual skills training with an eclectic approach significantly increased sexual function and its subscales such as sexual desire and stimulation compared to the control group (P < 0.01). However, there was no significant difference between the two groups in lubrication and orgasm subscales. Conclusions: It can be deduced that sexual skills training has an effective role in promoting sexual function in married women. Thus, this cost-effective therapy can be used to increase the sexual quality of women.

Background: Alzheimer’s disease (AD) is a progressive cognitive disorder that is generally age-related. Although there has been great research focusing on this disease, there is still a lack of reliable therapeutic methods. Amyloid- β (A β ) peptide has a critical function in neuropathology of AD. Stem cell therapy provides treatment by improving the neuronal system in neurodegenerative disorders. Human adipose-derived stem cells (hADSCs) are the most appropriate sources of stem cells due to their safety, high pro-liferative potential, and easy isolation. Objectives: Thepresentstudywasdesignedtoevaluatethehistologicalandbehavioralalterationsafterintravenousadministration of hADSCs in the AD rat model. Methods: In this study, 32 male rats were used in four groups, as follows: control, sham, AD rat model, and hADSCs-treated group. We used Morris Water Maze (MWM) for evaluating behavioral changes and Nissl staining for determining the histological studies. Results: In this study, the AD model was confirmed by behavioral and histological analysis. Behavioral results showed that the spatial memory improved after hADSCs injection in the AD rat model while the time spent in the target quadrant was significantly higher in the hADSCs-treated group than in the AD rat model group. On the other hand, the number of dead cells significantly decreased in the hADSCs-treated group as analyzed by Nissl staining. Conclusions: Our findings revealed that hADSCs could transfer into the brain and improve memory and neuronal damage in the AD rat model.
背景:阿尔茨海默病(AD)是一种进行性认知障碍，通常与年龄有关。尽管对这种疾病已经有了大量的研究，但仍然缺乏可靠的治疗方法。淀粉样蛋白- β (A β)肽在阿尔茨海默病的神经病理中起重要作用。干细胞疗法通过改善神经退行性疾病的神经系统提供治疗。人脂肪源性干细胞(hADSCs)由于其安全性、高促增殖潜力和易于分离而成为最合适的干细胞来源。目的:本研究旨在评估静脉给药hascs对AD大鼠模型的组织学和行为学改变。方法:选用雄性大鼠32只，分为4组:对照组、假手术组、AD大鼠模型组和hadscs治疗组。我们使用Morris水迷宫(MWM)评估行为变化，尼氏染色测定组织学研究。结果:本研究通过行为学和组织学分析证实了AD模型。行为学结果显示，在AD大鼠模型中注射hADSCs后，空间记忆得到改善，而在目标象限中停留的时间明显高于AD大鼠模型组。另一方面，通过尼氏染色分析，hadscs处理组的死细胞数量明显减少。结论:我们的研究结果表明，hascs可以转移到大脑中，改善AD大鼠模型的记忆和神经元损伤。

BackgroundStudies have shown that physical activity and the consumption of the medicinal herb saffron affect patients who have testicular problems and those who are prone to apoptosis. In this study, the effects of simultaneous eight-week exercise and crocin usage on the oxidation and anti-oxidation indices of male rats’ testicles subjected to apoptosis were investigated.MethodsIn this experimental study, 56 Wistar rats were randomly divided into 7 groups. The groups receiving supplement, exercise, and supplement received oral doses of 10 and 50 mg per kg of body weight for 8 weeks. The control group received only normal saline and the same amount of supplement as gavage. Fourty-eight hours after the last exercise session and after 10-12 hours of fasting overnight, blood samples were collected from animals after anesthesia and measured by dye-matase and catalase activity and the concentration of malondialdehyde in testicular tissue was measured. Statistical analysis was performed using SPSS software version 20 (P < 0.05).ResultsThe results showed that in all groups except the sick group through exercise and receiving a dose of 10 and 50 mg per kg crocin, dismutase and catalase indices increase, and the malondialdehyde index decreased and the T4 (doxorubicine + 10 mg crocin) group significantly increased in the antioxidant index and decreased in oxidative index (P < 0.05).ConclusionsThe findings of this study showed that endurance training and crocin dose-dependent injections by decreasing the toxicity of doxorubicin reduced the oxidative stress and free radicals and made good compatibility in the antioxidant system of testicular tissue in male rats.

BackgroundMaternal-fetal attachment (MFA) is the first relationship between a mother and her child, which generally begins during pregnancy. The maternal psychological state affects fetal growth and health. MFA is associated with the mental and psychological condition in pregnant women.ObjectivesThe aim of this study was the estimation of the variance of MFA, according to the personality traits in pregnancy.MethodsUsing a descriptive correlational study design, we studied pregnant women who were more than 24 weeks pregnant and were referring to the obstetric ward of the Kowsar Hospital, Shiraz, Iran, during May to June 2015. The sample size was estimated to be 200 women by Morgan’s table. A total of 29 participants were removed due to incomplete questionnaires, and 171 participants were selected. Data collection tools included demographic obstetric questionnaires, including obstetric information and demographic data, Cranly’s MFA scale, and NEO personality scale. Data were analyzed by the Pearson correlation coefficient and multiple regression, by using SPSS version 16.ResultsFindings from data analysis demonstrated a significant correlation between components of NEO personality with maternal-fetal attachment. Extroversion index (P < 0.001, R = -0.51) had the most significant relationship with MFA. Almost 33% of the variance in maternal-fetal attachment was predicted by personality trait. The extraversion (β = 0.48, P < 0.001) is the highest level of prediction. Neuroticism (β = 0.175), openness to experience (β = 0.131) and conscientiousness (β = 0.237), predicted the maternal-fetal attachment positively. Agreeableness (β = -0.026) was not predicted in the maternal-fetal attachment. In demographic variables, they were not predicted of MFA. There was a significant correlation between parity and maternal-fetal attachment (R = 0.190, P = 0.013).ConclusionsPersonality traits (except agreeableness) predict MFA for pregnant women. In addition, the psychological health of the mother and baby can be improved by identifying mothers based on personality traits, and therefore, by promoting behavioral attachment, health care providers should identify mothers who need additional psychological support during their pregnancy.
母胎依恋(MFA)是母亲和孩子之间的第一种关系，通常在怀孕期间开始。母亲的心理状态影响胎儿的生长和健康。MFA与孕妇的精神和心理状况有关。目的探讨妊娠期人格特征对MFA的影响。方法采用描述性相关研究设计，研究2015年5月至6月在伊朗设拉子(Shiraz) Kowsar医院产科病房转诊的怀孕24周以上的孕妇。摩根的表格估计样本量为200名女性。由于问卷不完整，共有29人被剔除，171人被选中。数据收集工具包括人口统计产科问卷，包括产科信息和人口统计数据，Cranly MFA量表和NEO人格量表。数据采用Pearson相关系数和多元回归分析，采用SPSS 16版。结果数据分析表明NEO人格的组成部分与母胎依恋之间存在显著的相关性。外向性指数与MFA的关系最显著(P < 0.001, R = -0.51)。近33%的母子依恋差异是由人格特质预测的。外向性(β = 0.48, P < 0.001)是预测的最高水平。神经质(β = 0.175)、经验开放性(β = 0.131)和责任心(β = 0.237)正预测母胎依恋。亲和性(β = -0.026)在母胎依恋中没有预测到。在人口统计变量中，它们不能预测MFA。胎次与母胎附着有显著相关性(R = 0.190, P = 0.013)。结论个性特征(随和性除外)对孕妇MFA有预测作用。此外，根据个性特征确定母亲可以改善母亲和婴儿的心理健康，因此，通过促进行为依恋，卫生保健提供者应该确定在怀孕期间需要额外心理支持的母亲。

In addition, the psychological health of the mother and baby can be improved by identifying mothers based on personality traits, and therefore, by promoting behavioral attachment, health care providers should identify mothers who need additional psychological support during their pregnancy.","PeriodicalId":23167,"journal":{"name":"Thrita","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76841851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Curcumin is a plant derivative with biological effects, including potential for the treatment of Parkinson’s disease (PD). It is known that monoamine oxidase B (MAO-B) is involved in PD due to its role in the degradation of various neurotransmitters like dopamine, the main declined factor in PD. Since MAO-B inhibitors (e.g. safinamide) are used as the support for the treatment of PD, we planned to evaluate the in silico interaction of curcumin with one subunit of the MAO-B enzyme in comparison with safinamide. The crystal structure of human MAO-B (PDB entry code 3PO7) was selected from the Protein Data Bank (https://www.rcsb.org). The molecular structures of curcumin (CID: 969516) and safinamide (CID: 131682) were obtained from PubChem (https://pubchem.ncbi.nlm.nih.gov). Chimera 1.8, AutoDock Tools-1.5.6 software and AutoDock4 software were used for this in silico study. The results revealed that the binding energies (ΔG)s of the conformations of curcumin and safinamide, showing the best down ΔG, were -11.15 kcal/mol and -11.09 kcal/mol, respectively. Moreover, the inhibition constants (Ki)s of both ligands were near quantities. Hence, it may suggest that curcumin and safinamide form nearly similar stability with the subunit of the MAO-B enzyme. More experimental studies may reveal the similarity of curcumin with safinamide about the inhibitory effect on MAO-B.

Background: Prefrontal cortex (PFC) is believed to manipulate cognitive control and mnemonic process to overcome interference. The interaction among memory, cognitive control, and language learning is still under debate. Objectives: This study investigated how episodic, semantic, and working memory (WM) as linguistically dependent retrieval cues can entail the interference process among EFL (English as a foreign language ) individuals. Methods: Combining the samples from five testing sectors in Shiraz, Iran, yielded data from 78 adult participants (33 males; 52 EFL independent users; 26 basic users; mean age 34.63). The participants took the test package of selection mechanism measures in resolving interference (SMMRI), including selection in semantic/episodic memory and WM/priming (backward printed reading comprehension). Both descriptive statistics (mean scores, standard deviations) and inferential statistics (Correlations, t-tests, interface resolution (IR)) were performed using SPSS software version 25.0. Results: There was a downward trend in the order of magnitude from episodic (OLD-NEW) toward semantic (high-selection) toward WM/priming. Also, there was a moderate/high correlation among the aforementioned memories. There was a significant difference in IR-scores between basic and independent users. Conclusions: Hierarchical process of compromises between L2 (Second language) memories indicated that the interactions of different cognitive sub-components played a central executive role. The difference between IR-scores revealed that training on WM tasks, which demanded higher activations in the PFC, could enhance the ability in resolving interference. Retrieval cues have limited concomitant memory capacity that integrate morphological, semantic, and syntactic features. However, men outperformed females in semantic selection, no significant gender difference was seen in episodic selection.

The application of traditional and industrial addictive drugs is expanding in the developed societies. Carvacrol is widely used in traditional medicine, and methamphetamine, directly and indirectly, affects all organs. According to the mechanism of methamphetamine, the therapeutic effects of antioxidants were recently considered in order to reduce methamphetamine abuse outcomes. The current study aimed at evaluating the anti-apoptotic effect of carvacrol on spermatogenesis of rats treated with methamphetamine. Thus, 32 adult male rats were randomly divided into four groups: positive control, negative control, sham, and experimental. Spermatogenic cells and testis tissue were evaluated using hematoxylin and eosin staining technique and the expression of P53 was assessed by Western blotting as a factor to induced apoptosis. The current study data showed that methamphetamine significantly reduced spermatogenic cells in the positive control group, while carvacrol increased these cells in the experimental group. Also, carvacrol decreased P53 expression in the experimental group compared with the positive control group (P < 0.05). Therefore, carvacrol had an anti-apoptotic effect by suppressing P53 protein expression. Altogether, carvacrol can reduce some of the common symptoms related to methamphetamine abuse including infertility and induction of apoptosis.
