Despite common incidence of GB virus C/Hepatitis G virus (GBV-C/HGV) and Torque Teno Virus (TTV) co-infections in subjects with Hepatitis C virus (HCV) infection, pathogenic role of these co-infections in HCV infected subjects has not been clear since studies have mostly been based on liver enzyme profile yielding variable results. Pro-inflammatory cytokines that participate in host immune response against viruses are generated as a consequence of triggering of related genes by Nuclear Factor Kappa B (NF-kB) that is a member of transcription family. Study of three pro-inflammatory cytokines e.g. interleukin 1 beta (IL-1β), Interleukin-6 (IL-6), interleukin-8 (IL-8) in a group of multi-transfused thalassemic subjects in relation to positivity for HCV, HGV and TTV infections showed elevated levels of these cytokines in serum as well as in supernatant of peripheral blood mononuclear cell (PBMCs) cultures in HCV-GBV-C/HGV co-infected subgroup compared to HCV mono-infected subgroup (p <0.05 for comparison of all three cytokines) while HCV-TTV co-infected subgroup showed lowering of these levels compared to HCV mono-infected subgroup (p <0.05 for comparison of all three cytokines). Levels of p65 component of NF-kB i.e.NF-kB p65 in nuclear extracts of lipopolysaccharide stimulated PBMCs correlated positively with the levels of pro-inflammatory cytokines in serum as well as that in supernatants of PBMC cultures in both HCV- GBV-C/HGV co-infected and HCV-TTV co-infected subgroups (p values ranging from <0.001 to 0.004). Levels of NF-kB p65 in nuclear extracts and levels of pro-inflammatory cytokines in serum as well as in supernatants of PBMC culture did not show any alteration compared to thalassemic subjects with HGV or TTV infections alone and healthy non-transfused subjects. Based on the inhibitory role of TTV on activation of NF-kB in TTV-HCV co-infected cases observed in the present study and the reported contribution of NF-kB towards development of hepatocellular carcinoma (HCC) due to establishment of chronicity, it may be worth evaluating if TTV or any component of TTV can be utilized as therapeutic vaccine against development of HCC in HCV infected subjects.
尽管GB病毒C/ G型肝炎病毒(GBV-C/HGV)和Torque Teno病毒(TTV)合并感染在丙型肝炎病毒(HCV)感染的受试者中发生率很高,但这些合并感染在HCV感染受试者中的致病作用尚不清楚,因为研究大多基于肝酶谱,结果不同。参与宿主对病毒免疫应答的促炎细胞因子是转录家族成员核因子κ B (NF-kB)触发相关基因的结果。三种促炎细胞因子如白细胞介素1β (IL-1β)、白细胞介素6 (IL-6)、白细胞介素8 (IL-8)与多次输血地中海贫血患者HCV阳性的关系研究在HCV- gbv - c /HGV共感染亚组中,与HCV单感染亚组相比,HCV- gbv - c /HGV共感染亚组的血清和外周血单核细胞培养上清中这些细胞因子的水平升高(三种细胞因子的比较p <0.05),而HCV-TTV共感染亚组与HCV单感染亚组相比,这些水平降低(三种细胞因子的比较p <0.05)。在HCV- GBV-C/ HCV- ttv共感染亚组和HCV- GBV-C/ HCV共感染亚组中,NF-kB p65成分即脂多糖刺激的PBMC核提取物中NF-kB p65的水平与血清中促炎细胞因子水平以及PBMC培养上清液中促炎细胞因子水平呈正相关(p值<0.001 ~ 0.004)。与单纯感染HGV或TTV的地中海贫血患者和未输血的健康受试者相比,核提取物中NF-kB p65水平和血清中促炎细胞因子水平以及PBMC培养上清液中未显示出任何变化。基于本研究中观察到的TTV对TTV-HCV共感染病例中NF-kB激活的抑制作用,以及NF-kB因慢性建立而对肝细胞癌(HCC)发展的贡献,TTV或TTV的任何成分是否可以用作抗HCV感染者HCC发展的治疗性疫苗,可能值得评估。

Background and Aim: The present study investigated the antimicrobial effect of Berberine as an endodontic irrigant on the microorganisms involved in persistent endodontic infections. In this experimental in vitro trial, organisms Enterococcus Faecalis, Staphylococcus Aureus, and Staphylococcus Epidermidis were assessed in a multi-species biofilm tooth model. Methods: Seventy-five single-rooted anterior teeth were collected and standardized to a length of 10mm. The teeth were randomly assigned into 5 groups. The teeth were then autoclaved to confirm being sterile. Afterwards, a biofilm consisting of the three selected bacteria was inoculated into the teeth and they were incubated for 21 days. Results: The comparison of the amount of reduction in viable bacterial counts after irrigation by different solutions among the groups was done by Kruskal-wallis test while the changes of viable bacterial counts before and after irrigation with each solution was done by Wilocoxon Signed Ranks test. No significant difference existed among the studied irrigation solutions regarding the mean reduction of total viable bacterial counts, neither did it exist regarding the viable staphylococcus aureus, staphylococcus epidermidis or Enterococcus faecalis counts after irrigation. MIC of berberine against staphylococcus aureus, staphylococcus epidermidis and Enterococcus faecalis species were 0.5ug/ml, 0.03ug/ml and 1ug/ml, respectively. These values were found to be 0.39ug/ml, 0.09ug/ml and 0.78ug/ml for NaOCl and 0.04ug/ml, 0.04ug/ml and 0.09ug/ml for chlorhexidine, respectively. Conclusion: it is concluded that Berberine can be used as a natural alternative instead of conventional root canal irrigants. However, more studies are required in order to confirm that characteristics of this substance are appropriate from other aspects.
背景与目的:本研究探讨了小檗碱作为牙髓冲洗剂对牙髓持续性感染微生物的抗菌作用。在这项体外实验中,我们在多物种生物膜牙齿模型中对粪肠球菌、金黄色葡萄球菌和表皮葡萄球菌进行了评估。方法:收集75颗单根前牙,标准化为10mm长。牙齿随机分为5组。然后用高压灭菌法确认牙齿是无菌的。然后,将选定的三种细菌组成的生物膜接种到牙齿中,培养21天。结果:采用Kruskal-wallis检验比较各组不同溶液灌后活菌数量的减少量,采用Wilocoxon sign Ranks检验比较各溶液灌前后活菌数量的变化。不同灌洗液对总活菌数量的平均降幅无显著差异,灌洗液对金黄色葡萄球菌、表皮葡萄球菌和粪肠球菌的活菌数量也无显著差异。小檗碱对金黄色葡萄球菌、表皮葡萄球菌和粪肠球菌的MIC分别为0.5ug/ml、0.03ug/ml和1ug/ml。NaOCl分别为0.39ug/ml、0.09ug/ml和0.78ug/ml,氯己定分别为0.04ug/ml、0.04ug/ml和0.09ug/ml。结论:小檗碱可作为传统根管冲洗剂的天然替代品。然而,为了从其他方面证实该物质的特性是合适的,还需要更多的研究。

The evolutionarily conserved Wnt signaling pathway plays essential roles during embryonic development, tissue homeostasis and differentiation. This pathway is deregulated in many cancers especially colorectal cancer. MiRNAs are a class of small noncoding RNAs that may play a major role in post transcriptional regulation of many genes and signaling pathway such as WNT signaling pathway. Here, we intended to investigate if miR-186-5p is capable of regulating WNT signaling pathway wia suppression TCF4 gene expression. miR-186-5p was bioinformatically predicted as a candidate regulator of TCF4 gene expression and then, in this experimental study, miR-186-5p was overexpressed in SW480 cell line and its increased expression was detected through quantitative reverse transcription polymerase chain reaction (RT-qPCR). The effect of miR-186-5p on WNT pathway was analysied with TOP/FOP flash assay in SW480 cell line. Finally, flow cytometery was used to inves tigate the effect of miR-186-5p overexpression on cell cycle progression in SW480 cell line. miR-186-5p was overexpressed in the SW480 cell line and its overexpression resulted in significant reduction of the TCF4 mRNA level. TOP/FOP flash assay, confirmed the negative effect of miR-186-5p on the Wnt pathway in SW480 cells. Finally, Overexpression of miR186-5p in SW480 cells resulted in cell cycle arrest in subG1 phase, detected by flow cytometry. Overall, accumulative results indi-cated that miR-186-5p by targeting TCF4 is potentially one of the regulators of the WNT signaling pathway.
进化上保守的Wnt信号通路在胚胎发育、组织稳态和分化过程中发挥着重要作用。这种途径在许多癌症中被解除调节,尤其是在癌症中。miRNA是一类小型非编码RNA,可能在许多基因和信号通路(如WNT信号通路)的转录后调控中发挥重要作用。在这里,我们打算研究miR-186-5p是否能够通过抑制TCF4基因表达来调节WNT信号通路。miR-186-5p被生物信息学预测为TCF4基因表达的候选调节因子,然后,在本实验研究中,miR-186-5p在SW480细胞系中过表达,并通过定量逆转录聚合酶链反应(RT-qPCR)检测其表达增加。在SW480细胞系中用TOP/FOP闪烁分析法分析了miR-186-5p对WNT通路的影响。最后,用流式细胞仪研究了miR-186-5p过表达对SW480细胞系细胞周期进程的影响。miR-186-5p在SW480细胞系中过表达,其过表达导致TCF4 mRNA水平显著降低。TOP/FOP快速测定证实了miR-186-5p对SW480细胞中Wnt途径的负面影响。最后,通过流式细胞术检测,miR186-5p在SW480细胞中的过表达导致细胞周期停滞在亚G1期。总之,累积结果表明,靶向TCF4的miR-186-5p可能是WNT信号通路的调节因子之一。

An assessment of the genetic diversity of the microsatellite locus mrjp3 in honeybee of European Apis mellifera subspecies was conducted. Differences in the frequency of alleles for the mrjp3 locus were found in honeybees of different evolutionary branches. Allele "529" was found to be specific for the Apis mellifera mellifera, evolutionary branch M, while alleles "406", "518", and "485" were characteristic of the southern subspecies of bees (A. m. carnica, A. m. carpatica (some researchers consider this breed as a derivative of A. m. carnica), and A. m. caucasica; evolutionary branches C and O, respectively). A high correspondence of the studied nucleotide sequences (>=99% identity) with the reference sequences (Genbank) was established indicating a high conservation of the repetitive region of the mrjp3 gene in A. mellifera subspecies inhabiting different geographic regions of Europe and Siberia. Locus mrjp3 is of considerable interest for further study as a candidate marker for differentiation of bee subspecies.
对欧洲蜜蜂亚种微卫星位点mrjp3的遗传多样性进行了评价。在不同进化分支的蜜蜂中发现mrjp3位点的等位基因频率存在差异。等位基因“529”是蜜蜂进化分支“蜜蜂蜜蜂”所特有的,而等位基因“406”、“518”和“485”是南方亚种蜜蜂(a . M . carnica)、a . M . carpatica(一些研究者认为该品种是a . M . carnica的衍生物)和a . M . caucasica)所特有的;进化分支C和O分别)。所研究的核苷酸序列与参考序列(Genbank)高度对应(>=99%),表明在生活在欧洲和西伯利亚不同地理区域的A. mellifera亚种中mrjp3基因的重复区域具有高度保守性。mrjp3基因座作为蜜蜂亚种分化的候选标记,值得进一步研究。

Introduction: The International Diabetes Federation (IDF) Announces 415 million people around the world are suffering from diabetes. There is a high proportion of UDM (undiagnosed diabetes) at the level of the world and particularly in developing countries. The number of people with UDM in Iran in 2015 are 2197.96 per 1000. Vitamin D3 deficiency is associated with increased risk of type 2 diabetes and for a long time, been recognized as a risk factor for glucose intolerance. Salivary composition, as the mirror of oral health, its use as a diagnostic tool is increasing and diabetes is also can be effective on the flow rate of saliva and its compounds. Analysis of saliva can be used as part of the evaluation of endocrine function. Material and Methods: In this case-control study in 2016 in Hamadan, we selected 57 newly diagnosed patients with type 2 diabetes mellitus with mean aged 47.73 years and 57 healthy controls with mean aged 45.36 years. By using Spitting method, 5ml of completely unstimulated saliva samples were collected from diabetic patients and control subjects. The serum and saliva 25(OH)Vit.Dconcentrations were measured by ELISA. The results are analyzed by SPSS 16.Results: Significant difference was found in serum concentrations between the two groups (p<0.001). But in unstimulated whole salivary 1, 25(OH) 2D3 concentrations between the two groups, difference was not significant and the relationship, was reversed. There was a significant correlation (P=0.013) between serum and saliva 1, 25(OH) 2D3concentrations in the control group. In other words, the correlation was approximately 0.33. Correlation between serum and saliva 1, 25(OH) 2D3 concentrations in case group was not significant. Serum levels of 1, 25(OH) 2D3 in 21.1% of control group, showed the inadequate level (Vit.D3= 20-29ng/ml) and in the case group, showed the critical situation and overall 91.2% of the newly diagnosed diabetics, suffered from lack of vitamin D3. According to the salivary levels of 1, 25(OH) 2D3, in general, a total of 58% of the case group, have deficiency of vitamin D3.Conclusion: The results was confirmed vitamin D3 deficiency in participating in the study population (both case and control). The findings showed that there is lower concentration of 1, 25(OH) 2D3 in serum and after that in saliva in diabetic patients that newly diagnosed. Saliva would play a helpful diagnostic role in the early detection, the monitoring and progression of diabetes, but still serum is the better method for detecting vit.D3 levels and more research needs to be done on saliva for detecting Vit.D3 concentrations.
简介:国际糖尿病联合会(IDF)宣布,全世界有4.15亿人患有糖尿病。在世界水平上,特别是在发展中国家,UDM(未确诊糖尿病)的比例很高。2015年,伊朗患有UDM的人数为2197.96/1000。维生素D3缺乏与2型糖尿病的风险增加有关,长期以来,维生素D3缺乏被认为是葡萄糖不耐受的风险因素。唾液成分作为口腔健康的镜子,其作为诊断工具的用途正在增加,糖尿病也可能对唾液及其化合物的流速产生影响。唾液分析可以作为内分泌功能评估的一部分。材料和方法:在2016年哈马丹的病例对照研究中,我们选择了57名新诊断的2型糖尿病患者,平均年龄47.73岁,以及57名健康对照,平均年龄45.36岁。采用Spitting法,从糖尿病患者和对照组中采集5ml完全未刺激的唾液样本。通过ELISA测定血清和唾液中25(OH)维生素D的浓度。结果:两组血清浓度差异有显著性(p<0.001),但在未刺激的全唾液1,25(OH)2D3浓度下,两组间差异无显著性,二者的关系相反。对照组血清和唾液1,25(OH)2D3浓度之间存在显著相关性(P=0.013)。换句话说,相关性大约为0.33。病例组血清和唾液1,25(OH)2D3浓度相关性不显著。21.1%的对照组的血清1,25(OH)2D3水平显示不足(维生素D3=20-29ng/ml),病例组的情况危急,总的来说,91.2%的新诊断糖尿病患者缺乏维生素D3。根据唾液中1,25(OH)2D3的水平,一般情况下,共有58%的病例组存在维生素D3缺乏症。结果表明,在新诊断的糖尿病患者中,血清和唾液中的1,25(OH)2D3浓度较低。唾液在糖尿病的早期检测、监测和进展中有助于诊断,但血清仍是检测vit的更好方法。D3水平,需要对唾液进行更多的研究来检测维生素D3的浓度。

Introduction: Vitamin D deficiency is a major public health problem. Low vitamin D levels associated with adverse health consequences such as musculoskeletal health, cognitive decline and progression of cancer and death. The lack of vitamin D associated with major risk factors for cardiovascular disease (CVD) includes hypertension is considered. The ability to assess the general health, disease and treatment outcomes through saliva as a non-invasive, inexpensive and simple method of interest is located. The aim of this study was a comparative study of salivary and serum levels of vitamin D3 in patients with a history of developing high blood pressure and a healthy person.Methods: This study was a case - control survey, in which 40 patients with high blood pressure were examined. The control group including 40 healthy subjects. Both groups were matched in terms of age and gender. After collecting samples of serum and saliva, the amount of vitamin D level samples were measured using ELISA method by electrochemiluminescence (ELC), and then analyzed the results using software SPSS 16 and statistical test including Chi Square Test, Independent-Samples, linear regression model, the Mann-Whitney Test and Spearman correlation coefficient.Results: There was no significant difference in the mean serum levels of vitamin D among patients and healthy subjects (p= 0.588). In addition, there was no significant difference in the mean salivary levels of vitamin D between patients and healthy subjects (p= 0.833). There was no significant relationship between salivary and serum level of vitamin D in healthy individuals (p= 0.095). As well as there was no significant correlation between salivary and serum level of vitamin D in patients (p= 0.5).Conclusions: This study showed that vitamin D is a measurable marker in saliva, but its analysis in saliva, may not be a reliable tool for determining the vitamin D levels.
维生素D缺乏是一个重大的公共卫生问题。维生素D水平低与肌肉骨骼健康、认知能力下降、癌症进展和死亡等不良健康后果有关。缺乏维生素D与心血管疾病(CVD)的主要危险因素相关,包括高血压。通过唾液评估一般健康、疾病和治疗结果的能力是一种无创、廉价和简单的方法。本研究的目的是对有高血压病史的患者和健康人的唾液和血清维生素D3水平进行比较研究。方法:对40例高血压患者进行病例对照调查。对照组为40名健康受试者。两组在年龄和性别上都是一致的。采集血清和唾液样品后,采用ELISA法电化学发光(ELC)测定样品中维生素D含量,并采用SPSS 16软件进行χ 2检验、独立样本检验、线性回归模型、Mann-Whitney检验和Spearman相关系数等统计检验。结果:两组患者血清维生素D水平差异无统计学意义(p= 0.588)。此外,患者与健康者的平均唾液维生素D水平无显著差异(p= 0.833)。健康人群唾液与血清维生素D水平无显著相关性(p= 0.095)。患者唾液与血清维生素D水平无显著相关性(p= 0.5)。结论:本研究表明,维生素D是唾液中可测量的标记物,但唾液中维生素D的分析可能不是确定维生素D水平的可靠工具。

Background: Mycobacterium tuberculosis is an infectious agent responsible for major health problems and a large number of mortalities. The prevalence of Mycobacterium tuberculosis infection varies across countries. Knowing the infection prevalence can aid in improving public health and reduce the associated costs. The aim of this study was to determine the prevalence of tuberculosis (TB) infection in suspected cases in Mashhad, Iran.Methods: All the clinical specimens suspected of TB infection were sent to a laboratory for diagnosis during -March 2017 to March 2018. The samples were analyzed microscopically using Ziehl–Neelsen staining, by polymerase chain reaction (PCR) to identify the Mycobacterium tuberculosis species using IS6110 primers, and the samples were also grown on Lowenstein–Jensen medium.Results: Of 2,755 clinical samples analyzed, 153 (5.55%) were identified as Mycobacterium tuberculosis-positive, of which 54.9% originated from females and 45.1% from males. The highest rate of infection was observed in spring, especially in May (15%). Most TB cases were found in patients in VIP (43.1%), thorax (17%), and internal (15%) wards. TB infection was mostly detected in bronchial tube (70%) and sputum (23.5%) samples. The most common positive smear was 1+ (36%). Of the 153 cases, (147) 96.1% were culture –positive and 2% were PCR-negative also 84.3% were smear –positive.Conclusion: The highest rate of infection occurred in spring, when the number of religious tourists entering the city was at its peak. Considering the sensitive location of this city, awareness regarding TB status can lead to improved health in the community and development of basic strategies to control and eliminate the transmission of this infection from Mashhad to other areas.
背景:结核分枝杆菌是造成重大健康问题和大量死亡的传染源。结核分枝杆菌感染的流行率因国家而异。了解感染流行率有助于改善公共卫生并降低相关成本。本研究的目的是确定伊朗马什哈德疑似病例中结核病(TB)感染的流行率。方法:在2017年3月至2018年3月期间,将所有疑似结核病感染的临床标本送往实验室进行诊断。使用Ziehl–Neelsen染色和聚合酶链式反应(PCR)对样本进行显微镜分析,以使用IS6110引物鉴定结核分枝杆菌物种,样本也在Lowenstein–Jensen培养基上生长。结果:在分析的2755份临床样本中,153份(5.55%)被鉴定为结核分枝杆菌阳性,其中54.9%来自女性,45.1%来自男性。感染率最高的是春季,尤其是5月份(15%)。大多数结核病病例发生在VIP(43.1%)、胸部(17%)和内部(15%)病房的患者中。结核感染主要在支气管(70%)和痰液(23.5%)样本中发现。最常见的阳性涂片为1+(36%)。在153例病例中,(147)96.1%为培养阳性,2%为PCR阴性,84.3%为涂片阳性。结论:春季感染率最高,进入该市的宗教游客数量达到峰值。考虑到这个城市的敏感位置,对结核病状况的认识可以改善社区的健康状况,并制定基本战略来控制和消除这种感染从马什哈德向其他地区的传播。

Introduction: Performing dental practices in the oral environment leads to the transmission of microorganisms in saliva and blood to working surfaces and dental devices and their infection. Preventing transmission of infection through these devices is an important task of a dentist. Hence, this research was conducted to evaluate the disinfection quality of the dental faculty units of Ahvaz Jundishapur University of Medical Sciences (AJUMS) in Iran.Materials and Methods: In order to evaluate the quality of disinfection of the units, sampling was performed from all glasses spittoon surfaces of 90 units of the clinical unit of the AJUMS dental faculty before and after disinfection by personnel. Then, the bacteria were cultured in a medium and examined.Results: The mean (and standard deviation) of the total infection of units of the dental faculty was 46534.4 (583380.4) colonies per 1 ml before disinfection and 40265.6 (52131.1) colonies per 1 ml after disinfection, reflecting significant decrease in number of bacterial colonies after disinfection (P <0.001). In addition, a significant decrease was seen in the number of bacterial colonies in the restoration, pediatric, orthodontic and diagnosis units (p <0.05), but the difference before and after disinfection was not significant in the prosthetic, endodontic, surgical and periodontal units. In addition, the most common types of microorganisms in the whole units of the dental faculty were pseudomonas aeruginosa, Staphylococcus aureus and Streptococcus, respectively, and after disinfection, the most common types of microorganisms were Pseudomonas aeruginosa, Staphylococcus aureus and Enterococcus, respectively.Conclusion: In general, this study showed that the disinfection method of units in dental faculty can not reduce the severity of infection of the units. Given what was stated, it is recommended that the method and the substances used to disinfect the unit to be changed.
引言:在口腔环境中进行牙科实践会导致唾液和血液中的微生物传播到工作表面和牙科设备并感染。预防感染通过这些设备传播是牙医的一项重要任务。因此,本研究旨在评估伊朗阿赫瓦兹·琼迪沙普尔医学科学大学(AJUMS)牙科教员单位的消毒质量,在人员消毒前后,从AJUMS牙科学院临床单元的90个单元的所有眼镜痰盂表面进行采样。然后,将细菌在培养基中培养并进行检查。结果:口腔科各单位总感染的平均值(和标准差)为消毒前每1ml 4653.4个菌落(583380.4),消毒后每1ml 40265.6个菌落(52131.1),反映出消毒后菌落数显著减少(P<0.001),修复单位、儿童单位、正畸单位和诊断单位的菌落数显著减少(p<0.05),但修复单位、牙髓单位、外科单位和牙周单位消毒前后的差异不显著。此外,口腔科全科最常见的微生物类型分别为铜绿假单胞菌、金黄色葡萄球菌和链球菌,消毒后最常见的细菌类型分别为绿脓杆菌、金黄色葡球菌和肠球菌。结论:总的来说,本研究表明,口腔科病房的消毒方法并不能降低病房感染的严重程度。鉴于所述内容,建议更改用于消毒装置的方法和物质。
