Background & objectives: Exercise, with beneficial effects on brain health and cognitive function reduces the destructive effects of some neurological diseases such as Alzheimer's. The aim of this study was to evaluate the effect of four weeks of aerobic exercise on cognitive function and expression of Sirt1, CREB and BDNF genes in the hippocampus of male Wistar rats with Alzheimer's disease. Methods: The statistical population included 18 male Wistar rats from the Pasteur Institute. Rats were randomly divided into three groups including Alzheimer's group, Alzheimer's disease-exercise group and a healthy control group. Alzheimer's disease group was induced by injecting Aβ42 into the hippocampus. Seven days after surgery, the rats performed the aerobic exercise for four weeks (five sessions per week at a speed of 10-15 m/min). They underwent behavioral tests 48 hours after the last training session. Twenty four hours later, rat hippocampal tissue was extracted. Sirt1, CREB and BDNF mRNAs were measured using Real time-PCR. Results: Learning and spatial memory performance decreased in rats of Alzheimer's disease group compared to a healthy control group (p˂0.001). Decreased mRNA expression of Sirt1, CREB and BDNF genes was observed in the hippocampal tissue of Alzheimer's disease group compared with the healthy control group (p˂0.001). Alzheimer's rats with intermittent aerobic exercise had improved learning function, spatial memory and increased mRNA expression levels of Sirt1, CREB and BDNF genes in comparison with Alzheimer's disease group (p˂0.001). Conclusions: Periodic aerobic exercise in rats with Alzheimer's disease can improve spatial learning and memory by positively regulating the Sirt1/ CREB/ BDNF signaling pathway in hippocampal tissue.
背景与目的:运动对大脑健康和认知功能有有益的影响,可以减少一些神经系统疾病(如阿尔茨海默病)的破坏性影响。本研究旨在评估4周有氧运动对老年痴呆症雄性Wistar大鼠海马认知功能及Sirt1、CREB和BDNF基因表达的影响。方法:统计种群为巴斯德研究所Wistar雄性大鼠18只。将大鼠随机分为阿尔茨海默病组、阿尔茨海默病-运动组和健康对照组。阿尔茨海默病组海马注射Aβ42诱导。术后7天,大鼠进行为期四周的有氧运动(每周5次,速度为10-15 m/min)。在最后一次训练后48小时,他们接受了行为测试。24小时后,提取大鼠海马组织。采用Real - time-PCR检测Sirt1、CREB和BDNF mrna。结果:与健康对照组相比,阿尔茨海默病组大鼠的学习和空间记忆能力下降(p小于0.001)。与健康对照组相比,阿尔茨海默病组海马组织中Sirt1、CREB和BDNF基因的mRNA表达降低(p小于0.001)。与阿尔茨海默病组相比,间歇性有氧运动的阿尔茨海默病大鼠的学习功能、空间记忆得到改善,Sirt1、CREB和BDNF基因mRNA表达水平升高(p小于0.001)。结论:周期性有氧运动可通过正向调节海马组织Sirt1/ CREB/ BDNF信号通路改善老年痴呆症大鼠的空间学习记忆。

Background & objectives: The deposition of amyloid beta (Aβ) peptide in the brain is one of the most important features of Alzheimer's disease. In addition to memory loss, Aβ can lead to depression behavior. Alpha-pinene is a type of monoterpene that has antioxidant, antiinflammatory, and neuroprotective effects. Here, by using an animal model for Alzheimer's disease, we investigated the effect of alpha-pinene on neuronal cell death in the hippocampus and depression induced by Aβ1-42. Methods: Male Wistar rats weighing 240-260 g were divided into four groups including control, alpha-pinene, Aβ, and Aβ-alpha-pinene. Rats were placed in stereotaxic surgery apparatus and Aβ1-42 was injected into the hippocampus (4 μg per side) and alpha-pinene was treated intraperitoneally (50 mg/kg) for 14 consecutive days. At the end of the course, the level of depression was assessed using the forced swimming test. The animals' hippocampus was also examined microscopically after Nissl staining. Results: Intra-hippocampal injection of Aβ1-42 increased the total immobility time in the forced swimming test (p<0.01), decreased the number of pyramidal neurons in the CA1 area (p<0.001), and reduced the thickness of the neuronal layer in this region of the hippocampus. Treatment with alpha-pinene largely prevented these changes. Conclusion: It can be concluded that alpha-pinene decreased the beta-amyloid-induced depressive behavior in rats and inhibited the neuronal loss, suggesting that this neuroprotective compound may have a critical role in depression. Alpha-pinene is probably a suitable therapeutic strategy for repressing Aβ-induced neurodegeneration.
背景与目的:淀粉样蛋白β(Aβ)肽在大脑中的沉积是阿尔茨海默病最重要的特征之一。除了记忆力丧失外,Aβ还会导致抑郁行为。α-蒎烯是一种单萜,具有抗氧化、抗炎和神经保护作用。在这里,通过使用阿尔茨海默病的动物模型,我们研究了α-蒎烯对海马神经元细胞死亡和Aβ1-42诱导的抑郁症的影响。方法:雄性Wistar大鼠体重240-260g,分为四组,包括对照组、α-蒎烯组、Aβ组和Aβ-α-松果烯组。将大鼠置于立体定向手术装置中,将Aβ1-42注射至海马(每侧4μg),并连续14天腹膜内注射α-蒎烯(50mg/kg)。课程结束时,使用强迫游泳测试来评估抑郁程度。Nissl染色后,还对动物的海马进行了显微镜检查。结果:在强迫游泳试验中,海马内注射Aβ1-42增加了总不动时间(p<0.01),减少了CA1区锥体神经元的数量(p<0.001),并减少了海马该区神经元层的厚度。α-蒎烯治疗在很大程度上阻止了这些变化。结论:α-蒎烯降低了β-淀粉样蛋白诱导的大鼠抑郁行为,抑制了神经元的丢失,提示该神经保护化合物可能在抑郁症中发挥关键作用。α-蒎烯可能是抑制aβ诱导的神经退行性变的合适治疗策略。

Background & objectives: Obesity and osteoporosis are major problem that their prevalence is increasing. Physical activity can be effective in the prevention of osteoporosis by some mechanisms such as changes in anthropometrics variables. Body mass index (BMI) in men and women is closely related to bone mineral density (BMD). However, the relationship varies between BMI and BMD according to the different studies. Therefore, the aim of this study was to investigate the relationship between body mass index and lumbar bone mineral density in active and inactive middle-aged women. Methods: Sixty active, middle-aged women and 60 inactive women in the age range of 50 to 65 years, with medical records and clinical trials were selected in Milad Hospital in Tehran. Body mass index was calculated and bone mineral density was measured by DEXA scan in the lumbar spine (L1 to L4). Independent t-test and Pearson correlation coefficient were used to evaluate the data. SPSS software version 26 was used for data analysis. Results: The results of this study showed that in the active group in L1, L3 and L4 lumbar vertebrae (p=0.034, p=0.017, p=0.019, respectively), and in the inactive group in L3 and L4 vertebrae (p=0.034, p=0.022, respectively), there was a positive and significant relationship between body mass index and bone mineral density. No significant relationship was found in other lumbar vertebrae of both groups. Conclusion: The results of the present study showed that weight gain and consequently BMI among active women reduce the risk of osteoporosis. Physical activity in women seems to lead to more muscle mass, which in turn leads to an increase in bone mineral density. Considering this issue, it can be said that one of the applications of the results of the present study is the use of this index in predicting the bone density of individuals.
背景与目的:肥胖和骨质疏松症是目前我国骨质疏松症发病率不断上升的主要问题。体育活动可以通过一些机制,如人体测量变量的变化,有效预防骨质疏松症。男性和女性的体重指数(BMI)与骨密度(BMD)密切相关。然而,根据不同的研究,BMI和BMD之间的关系各不相同。因此,本研究的目的是调查活跃和不活跃的中年妇女的体重指数与腰椎骨密度之间的关系。方法:选择德黑兰米拉德医院有病历和临床试验的60名活跃的中年妇女和60名不活跃的妇女,年龄在50至65岁之间。通过DEXA扫描计算腰椎(L1至L4)的体重指数并测量骨密度。采用独立t检验和Pearson相关系数对数据进行评价。数据分析采用SPSS软件26版。结果:本研究结果表明,活动组L1、L3和L4腰椎(分别为p=0.034、p=0.017、p=0.019)和非活动组L3、L4椎骨(分别为0.034、p=0.022)的体重指数与骨密度呈正相关。在两组的其他腰椎中均未发现明显的相关性。结论:本研究的结果表明,运动女性的体重增加和BMI降低了患骨质疏松症的风险。女性的体育活动似乎会导致更多的肌肉,进而导致骨密度的增加。考虑到这个问题,可以说,本研究结果的应用之一是使用该指数来预测个体的骨密度。

Background & objectives: Considering the high prevalence of body image dissatisfaction and its consequences, it is necessary to consider effective interventions to reduce it. The aim of this study was to investigate the effect of a balanced low calorie diet (BLCD) and slight weight loss on the body image score and its subscales. Methods: In this clinical trial, 74 apparently healthy, non-pregnant, non-lactating and nonmenopausal women (age range: 18-49 years with body mass index range: 27.5-40 kg/m) were selected using random sampling method from a nutrition clinic in their first visit in Ardabil city between November 2019 and February 2020. Data collection was done by Anthropometric measurements and multidimensional body self-relations questionnaire. The paired T-test was used to compare the changes during 4 week balanced low calorie diet intervention. BLCD was an individualized diet with an energy deficit of 500 calories of daily energy intake that was calculated from 3-day food records for every person. Results: After 4 weeks, BLCD resulted in a significant decrease in body weight (p=0.001), body mass index (p=0.001), waist circumference (p=0.002), waist to height ratio (p=0.012), abdominal volume index (p=0.009) and conicity index (p=0.045) and a significant increase in the subscale scores of fitness evaluation (p=0.01), health orientation (p=0.03), body area satisfaction (p=0.01) and overweight preoccupation (p=0.001). Conclusion: According to the results, it seems that even slight weight loss with a balanced low-calorie diet can be effective in improving anthropometric indices and some subscales of body image in 4 weeks. These results support the effectiveness of short-term interventions.
背景与目的:考虑到身体形象不满意的高患病率及其后果,有必要考虑有效的干预措施来减少这种不满意。本研究的目的是调查均衡低热量饮食(BLCD)和轻度减肥对身体形象评分及其分量表的影响。方法:在这项临床试验中,使用随机抽样方法从2019年11月至2020年2月期间首次访问阿达比尔市的营养诊所中选择了74名明显健康、未怀孕、未哺乳和未绝经的女性(年龄范围:18-49岁,体重指数范围:27.5-40 kg/m)。数据收集采用人体测量法和多维身体-自我关系问卷。配对T检验用于比较4周均衡低热量饮食干预期间的变化。BLCD是一种个性化饮食,根据每个人的3天食物记录计算出的每日能量摄入不足500卡路里。结果:4周后,BLCD使体重(p=0.001)、体重指数(p=0.001,结论:根据研究结果,即使是轻微的减肥和均衡的低热量饮食也能在4周内有效地改善人体测量指标和一些身体形象分量表。这些结果支持短期干预措施的有效性。

Background & objectives: Vincristine (VIN) is a broad-spectrum anticancer drug has been used to treat various cancers. Resveratrol (Res) is a natural polyphenol found in many plant sources. Many studies have reported anti-inflammatory and antioxidative effects of resveratrol. We have explored the protective effect of resveratrol on vincristine-induced oxidative stress in mouse ovarian tissue. Methods: In this study, 32 female mice weighing 25-30 grams were randomly divided into four groups (each group n=8): 1control group, 2Vingroup, 3Vin-Res group and 4Res group. The mice received a single IP injection of vincristine (3 mg/kg) weekly for 4 weeks. Res treatment was done 28 days by gastric gavage (daily 30 mg/kg).At the end of the study, Malondialdehyde (MDA) and total antioxidant capacity (TAC) and the antioxidant activity of superoxide dismutase (SOD) and glutathione peroxidase (GPx) enzymes were measured in ovarian tissue and uterus of the studied animals. Also, ovarian follicles were counted. Results: The results indicated that the MDA level was elevated and TAC, GPx as well as SOD activities were decreased in Vingroup significantly. Resveratrol reduced MDA level and increased GPx and SOD activities in Vin-Res group significantly. Also histological findings showed that Res increased primordial and primary follicles and reduced atretic follicles in Vin-Res group significantly. Conclusions: These results indicate the protective effect of resveratrol on ovarian and uterine tissue against oxidative damage of vincristine in mice.
背景与目的:长春新碱(VIN)是一种广谱抗癌药物,已被用于治疗各种癌症。白藜芦醇是一种天然多酚,存在于多种植物中。许多研究报道了白藜芦醇的抗炎和抗氧化作用。我们已经探索了白藜芦醇对长春新碱诱导的小鼠卵巢组织氧化应激的保护作用。方法:将32只体重25-30克的雌性小鼠随机分为4组(每组n=8):1对照组、2对照组、3Vin-Res组和4Res组。小鼠每周接受长春新碱(3mg/kg)的单次IP注射,持续4周。Res灌胃处理28天(每天30mg/kg),研究结束时,测定研究动物卵巢组织和子宫中丙二醛(MDA)、总抗氧化能力(TAC)以及超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GPx)的抗氧化活性。同时,对卵泡进行计数。结果:Vin组大鼠血清MDA含量升高,TAC、GPx及SOD活性降低。白藜芦醇显著降低Vin-Res组MDA水平,提高GPx和SOD活性。组织学结果还显示,在Vin-Res组中,Res显著增加了原始卵泡和初级卵泡,减少了闭锁卵泡。结论:白藜芦醇对长春新碱氧化损伤小鼠卵巢和子宫组织具有保护作用。

After the first phase of blood sampling, both groups were performed one session of acute circular strength training, then, the second phase blood sampling was performed. 48 hours later, the experimental group performed 8 weeks of circular resistance training, three sessions per week as in the acute strength training and were immersed immediately after exercise, 20minutes at 5-10°C in cold water and used 150mg curcumin supplementation. Forty eight hours after the last training session and last using curcumin, blood sampling was performed in both groups. Then, both experimental and control groups performed the second acute circular strength training and the fourth stage blood sampling was performed. The differences of variables at different time intervals were compared with 2×4 two-way ANOVA and differences between the two groups were investigated with Independent-Samples T-Test at significance level of p<0.05. Results: Creatine kinase and white blood cells significantly increased in both groups after the first acute strength activity (p=0.049). Performing 8 weeks of resistance training-cold water immersion and curcumin supplementation, significantly decreased creatine kinase and white blood cell counts (p=0.024). Also, 8 weeks of resistance training-cold water immersion and curcumin supplementation, significantly reduced creatine kinase and white blood cells following acute second strength activity (p=0.021). Conclusion: Appears to, 8-week resistance training-cold water immersion and curcumin supplementation following a session of acute strength training reduce muscle injury and inflammation in futsal players men.

Background & objectives: Due to the increasing prevalence of bacterial resistance, there is a growing attention to application of auxiliary treatment of pharyngitis. The aim of this study was to investigate the effect of honey throat spray in the auxiliary treatment of patients with a diagnosis of pharyngitis. Methods: At the start, different physicochemical quality parameters of the honey sample were evaluated. Then, the bottles of honey and the placebo throat spray were prepared. The numbers of 70 patients with the diagnosis of pharyngitis were included in a one-step and double-blinded study. In addition to standard treatment, each patient received either one of the honey or placebo throat spray. The clinical symptoms of the patients were compared between the two groups at baseline and then at 24 hours, 48 hours, 5 days and 10 days after the starting the treatment procedure. Results: As per results, the quality of honey sample was met to the standard honey criteria. The treatment and placebo groups were statistically similar in terms of demographic specifications or clinical symptoms at the time to enter the study. Pharyngitis recovery was better in treatment group than in the placebo group; this positive effect was statistically significant for symptoms of morning phlegm and painful swallowing, 24 hours after the starting treatment. In treatment group, after 48 hours, symptoms of fever and painful swallowing were resolved, while this indicator was 23% in placebo group. Also, throat pain of 85.71% of patients in treatment group and 17.14% of patients in placebo group was relieved. Overall, the mean recovery time in treatment group was shorter than placebo group. Conclusion: The findings of this study showed that the use of honey throat spray as auxiliary treatment of pharyngitis can improve the clinical symptoms of pharyngitis and reduce recovery time.

Background & objectives: Physical training and some supplements through different mechanisms could be effective in reducing apoptosis; the aim of this study was to investigate the effect of endurance training and supplementation of Persia Rosa extract on mitochondrial apoptosis of myocardium. Methods: In this experimental study, 52 male rats were randomly assigned into five homogeneous groups, three-month control, six months control, Persia Rosa supplement, endurance training and endurance training+Persia Rosa. Training groups participated in endurance training protocol for 12 weeks. The Persia Rosa and endurance training+Persia Rosa groups received 1 gram Persia Rosa extract per kg body weight. After the implementation of the training protocol and consumption of the extract, the surgical and cardiac tissue extraction procedures were performed. The data were analyzed by ANOVA test and Bonferroni post hoc tests at the significant level of less than 5% using SPSS-22 software. Results: The results showed that Bax/Bcl-2 ratio and Caspase-3 gene expression were significantly decreased in endurance training and endurance training+Persia Rosa groups to the control group (p˂0.05). Bax/Bcl-2 showed a significant decrease in the Persia Rosa supplement group (p˂0.05), but Caspase-3 was not significant in the Persia Rosa supplement group. Conclusion: It is expected that the effect of endurance training with consumption of Persia Rosa extract on Bax/Bcl-2 ratio and Caspase-3 will provide a good platform for caspase mechanisms and apoptosis processes in the myocardium of rats.

Background & objectives: Drug-repurposing is the study on application of existing drugs for treatment or control of other diseases. Major advantage of the technique relies on a nominated drug molecule that is applied for pharmacodynamics optimization due to lack of serious pharmacokinetics challenges. According to the importance of the subject, a present contribution has been dedicated to the in-silico analysis of a few drug classes with the aim of achieving potential anti-leishmanial pharmacophores. Methods: 3D structure of protein targets within leishmania parasite were retrieved from Brookhaven Protein Data Bank (PDB) on the basis of literature reports to evaluate the related complexes with drugs via molecular docking. Qualitative and quantitative analysis of drugtarget interaction patterns in docked complexes offered drugs with higher binding affinities toward targets and finally structural patterns or hypothetical anti-leishmanial pharmacophores were proposed with regard to the top-ranked pharmaceutical compounds. Results: Highest free binding energy could be estimated for Nateglinide in binding to farnesyl diphosphate synthase (ΔGb -13.30 kcal/mol). Among steroids, Norgestrel synthase (ΔGb -9.48 kcal/mol) and Testosterone synthase (ΔGb -8.05 kcal/mol) exhibited higher enzyme binding affinities and Arg82 was a key residue in making hydrogen bonds. Within fused tricyclic structural patterns, mirtazapine exhibited highest binding affinity to deoxy uridine triphosphate (ΔGb -8.64 kcal/mol). In Carbamazepine, amide substituent of the central ring facilitated the formation of two effective hydrogen bonds with Gln21 and Asn25 in deoxy uridine triphosphate. Conclusion: On the basis of obtained results for steroids and fused tricyclic scaffolds, it will be possible to design molecules that can inhibit several pathogenic targets simultaneously.
背景与目的:药物再利用是对现有药物用于治疗或控制其他疾病的研究。该技术的主要优势依赖于指定的药物分子,由于缺乏严重的药代动力学挑战,该分子被应用于药效学优化。根据该主题的重要性,目前致力于对一些药物类别进行计算机分析,目的是实现潜在的抗利什曼原虫药效团。方法:在文献报道的基础上,从Brookhaven蛋白质数据库(PDB)中检索利什曼原虫体内蛋白质靶标的三维结构,通过分子对接评估与药物的相关复合物。对接复合物中药物-靶标相互作用模式的定性和定量分析提供了对靶标具有更高结合亲和力的药物,最后针对排名靠前的药物化合物提出了结构模式或假设的抗利什曼原虫药效团。结果:在与法尼二磷酸合成酶结合时,可以估计出那格列奈的最高自由结合能(ΔGb-13.30kcal/mol)。在类固醇中,Norgestrel合成酶(ΔGb-9.48 kcal/mol)和睾酮合成酶(ΔGb-8.05 kcal/mol。在稠合三环结构模式中,米氮平对脱氧尿苷三磷酸表现出最高的结合亲和力(ΔGb-8.64 kcal/mol)。在卡马西平中,中心环的酰胺取代基促进了脱氧尿苷三磷酸中与Gln21和Asn25形成两个有效氢键。结论:在获得类固醇和融合三环支架的结果的基础上,将有可能设计出能够同时抑制多种致病靶标的分子。
