Background and Objectives: One of the predisposing factors for postural sway changes in patients with knee osteoarthritis is the severity of knee pain. Therefore, the purpose of this study was to evaluate the relationship between pain severity and static and dynamic balance indices in patients with knee osteoarthritis.Materials and Methods: 15 patients with knee osteoarthritis were selected through simple non-probability sampling. Static and dynamic balance indices were also measured by Biodex system, the pain severity by the Visual Analogue Scale (VAS) in two pre and post time intervals. The treatment was performed for the balance trainings group for 3 weeks and 5 times per week. Paired statistical t-test and Pearson test were used to analyze the data.Results: The results showed that balance trainings resulted in significant improvement in pain severity and dynamic and static balance indices. There was a significant direct correlation between pain severity and anterior-posterior stability index and medial-lateral stability index on two feet with the closed eyes with exercise, respectively (rho = 0.52, p = 0.04) and (rho = 0.53, p = 0.03). There was also a significant indirect correlation between pain severity and anterior-posterior stability index on the affected leg with the closed eyes (rho = 0.60, p = 0.01).Conclusion: The results of the study confirm the direct and indirect relationship between dynamic balance indices and pain intensity; in the future studies the effect of pain on neuromuscular factors should be considered.
背景和目的:膝关节骨性关节炎患者姿势摆动变化的诱发因素之一是膝关节疼痛的严重程度。因此,本研究的目的是评估膝骨关节炎患者的疼痛严重程度与静态和动态平衡指数之间的关系。材料与方法:采用简单的非概率抽样方法,选取15例膝骨关节炎患者。还通过Biodex系统测量静态和动态平衡指数,通过视觉模拟量表(VAS)在两个前后时间间隔内测量疼痛严重程度。平衡训练组治疗3周,每周5次。采用配对统计t检验和Pearson检验对数据进行分析。结果:平衡训练能显著改善患者的疼痛程度和动静态平衡指标。双足运动闭眼后疼痛程度和前后稳定性指数、内外侧稳定性指数有显著的正相关,分别为(rho=0.52,p=0.04)和(rho=0.053,p=0.03)。闭着眼睛受影响的腿的疼痛严重程度与前后稳定指数之间也存在显著的间接相关性(rho0.60,p=0.01)。结论:研究结果证实了动态平衡指数与疼痛强度之间的直接和间接关系;在未来的研究中,应考虑疼痛对神经肌肉因素的影响。

Background and aim: Spirituality is considered as one of the dimensions of health, along with physical, psychological and social health which includes an element of excellence and transcendence. However, it is unclear whether contemporary medical professors in Iran still considering this concept in their training program. This study assesses the professors' attitude toward considering spirituality and spiritual counseling and training during medical education among medical students.Materials and methods: This is a qualitative study with conventional content analysis method. 43 participants, who were main stakeholders in medical education were selected by convenience sampling. Data were collected using structured interviews from September to October 2017, which continued until data saturation.Ethical consideration: the principles of ethics and integrity in the research, citation and literature analysis were taken into consideration.Finding: Three main themes and their categories were extracted from analysis of data. The themes are (1) helping to solve the students' spiritual problems and challenges (2), Psycho-spiritual characteristics of medical student (3), training spiritual concepts.Conclusion: A majority of professors acknowledged the use of spirituality concepts in medical education. It seems that implementation of such programs requires attention to facilitating factors and challenges proposed by those involved.

Mycoplasma agalactiae pathogen is the main cause of agalactia in small ruminants and as such, results in some economic losses in Iran. Contagious agalactia disease should be regarded as a syndrome, caused by various Mycoplasmas which infect several organs. In the present study, 30 suspected samples from 11 provinces of Iran were isolated from mammary gland, joint and eyes of sheep and goats and subjected to genus and species detection via PCR technique for 2 genes. These Mycoplasma strains and three Iranian vaccinal strains of Mycoplasma agalactiae were submitted to sequence analysis of a surface lipoprotein called p40 protein. Based on a comparative study between Iranian strains and PG2 Spanish strain of Mycoplasma agalactiae, most Iranian strains presented 97% homology, whereas some strains showed 80-88% and three vaccinal strains were associated with 99% homology. According to PCR and bioinformatics analysis outcomes, 6 provinces of Iran were recognized as infection areas with different expressions of this effecter protein, suggesting that finding the individual characteristics of a particular effecter may require empirical testing for vaccination. Finally, the selected sequence of p40 gene was cloned into pGEMB1cloning vector and subsequently expressed in Escherichia coli by pET-22b+ expression plasmid under the control of the T7 promoter. The expression of this fusion protein was absorbed and confirmed by SDS-PAGE. The recombinant P40 protein was expressed with a molecular mass of 37 kDa on SDS-PAGE. The sera taken from rabbits infected with Mycoplasma agalactiae produced polyclonal antibody which was then used for westernblotting. The rabbits were bled 10 days after the booster immunization using cardiac puncture. Significantly, the use of recombinant specific antigens instead of other tools for diagnosis of a disease could improve the discrimination and separation of positive and negative animals in the area under investigation and therefore, it can be applied to control infected animals and reduce economic losses.
无乳支原体病原体是导致小反刍动物无乳的主要原因,因此在伊朗造成了一些经济损失。传染性无乳病是一种由多种支原体感染多个脏器引起的综合征。本研究从伊朗11个省的绵羊和山羊的乳腺、关节和眼睛中分离到30份疑似标本,采用PCR技术对2个基因进行属和种检测。这些支原体菌株和三个伊朗无乳支原体疫苗株被提交进行表面脂蛋白p40蛋白的序列分析。对伊朗株与无乳支原体PG2西班牙株的同源性进行比较,伊朗株的同源性大部分为97%,部分为80 ~ 88%,3株疫苗株的同源性为99%。根据PCR和生物信息学分析结果,伊朗6个省被确认为该效应蛋白表达不同的感染区,这表明发现特定效应蛋白的个体特征可能需要对疫苗接种进行经验检测。最后将选定的p40基因序列克隆到pgemb1克隆载体上,在T7启动子控制下,通过pET-22b+表达质粒在大肠杆菌中表达。该融合蛋白的表达被SDS-PAGE吸收并证实。重组P40蛋白在SDS-PAGE上的分子量为37 kDa。无乳支原体感染家兔血清产生多克隆抗体,进行免疫印迹。兔经心脏穿刺强化免疫后10 d出血。值得注意的是,使用重组特异性抗原代替其他工具进行疾病诊断可以改善调查地区阳性和阴性动物的区分和分离,因此可用于控制感染动物并减少经济损失。

Background: Zirconia ceramics have recently been widely used in dentistry because these materials are very favorable for chemical, dimensional stability, mechanical strength and hardness, Zolid FX (Ceramill Zolid FX, Amann Girrbach AG) is a type of zirconia. In this study, we have tried to measure the effects of different methods of surface preparation of full-contour restoration on the degree of material release and cellular response, so that we can recommend a method with lower tissue damage.Methods: In this study, Twenty blocks were prepared by CAD / CAM with dimensions of 5.5 mm in diameter and 3 mm in thickness and randomly divided into four groups. The laser used in this study is a co2 laser (Ultra-dream pluse, guro-gu seul, Korea). Comparison of the groups with the intact group was carried out two by two. The control group was compared by ANOVA and the groups with significant differences (with a significant percentage of 0.05) were compared by TUKEY statistical test.Conclusion and Results: Delivering one-stage, non-glazed-polished zirconium restorations can result in incompatible cellular response and is detrimental to the health of the periodontal tissue surrounding the restoration. It is also recommended that if the restoration due to the adjusting of clinician lose the glazed layer should not be delivered intact, at least prepare by polishing method, also if the laser is available in the clinic, then the surface restoration will be prepare using it, although it has not been routinely used due to lesser access to lasers in clinics.
背景:氧化锆陶瓷最近在牙科中得到了广泛的应用,因为这些材料在化学、尺寸稳定性、机械强度和硬度方面都非常有利,Zolid FX(Ceramill Zolid-FX,Amann Girrbach AG)是一种氧化锆。在这项研究中,我们试图测量不同的全轮廓修复表面处理方法对材料释放程度和细胞反应的影响,以便我们可以推荐一种组织损伤较低的方法。方法:本研究采用CAD/CAM技术制备了20个直径为5.5mm、厚度为3mm的试块,并将其随机分为四组。本研究中使用的激光器是一种二氧化碳激光器(Ultra dream pluse,guro gu-seul,韩国)。两组与完整组的比较是逐组进行的。对照组通过ANOVA进行比较,具有显著差异(显著百分比为0.05)的组通过TUKEY统计检验进行比较。结论和结果:提供一期、无釉抛光锆修复体会导致不相容的细胞反应,并对修复体周围牙周组织的健康有害。还建议,如果修复体由于临床医生的调整而丢失了釉层,则不应完好无损地交付,至少应通过抛光方法进行准备,如果诊所中有激光,则表面修复体将使用激光进行准备,尽管由于诊所中使用激光的机会较少,因此尚未常规使用激光。

Streptococcus sanguinis is a commensal and early colonizer of oral cavity as well as an opportunistic pathogen of infectious endocarditis. Extracting the soluble proteome of this bacterium provides deep insights about the physiological dynamic changes under different growth and stress conditions, thus defining "proteomic signatures" as targets for therapeutic intervention. In this protocol, we describe an experimentally verified approach to extract maximal cytoplasmic proteins from Streptococcus sanguinis SK36 strain. A combination of procedures was adopted that broke the thick cell wall barrier and minimized denaturation of the intracellular proteome, using optimized buffers and a sonication step. Extracted proteome was quantitated using Pierce BCA Protein Quantitation assay and protein bands were macroscopically assessed by Coomassie Blue staining. Finally, a high resolution detection of the extracted proteins was conducted through Synapt G2Si mass spectrometer, followed by label-free relative quantification via Progenesis QI. In conclusion, this pipeline for proteomic extraction and analysis of soluble proteins provides a fundamental tool in deciphering the biological complexity of Streptococcus sanguinis.

血链球菌是口腔的共栖和早期定植者,也是感染性心内膜炎的机会致病菌。提取这种细菌的可溶性蛋白质组可以深入了解不同生长和胁迫条件下的生理动态变化,从而确定“蛋白质组特征”作为治疗干预的靶点。在本方案中,我们描述了一种实验验证的方法,从血链球菌SK36菌株中提取最大的细胞质蛋白。使用优化的缓冲液和超声步骤,采用了打破厚细胞壁屏障和最小化细胞内蛋白质组变性的组合程序。提取的蛋白质组采用Pierce BCA蛋白定量法进行定量,蛋白条带采用考马斯蓝染色进行宏观评价。最后,通过Synapt G2Si质谱仪对提取的蛋白质进行高分辨率检测,然后通过Progenesis QI进行无标记相对定量。总之,这个蛋白质组学提取和可溶性蛋白分析的管道为破译血链球菌的生物学复杂性提供了一个基本的工具。
