Direct diagnosis of Leishmania species on serosity materials punctured from cutaneous leishmaniasis patients using PCR-RFLP

This study was aimed at identifying the Leishmania species using serosity materials punctured from skin lesions of cutaneous leishmaniasis (CL) patients by using internal transcribed spacer1 (ITS1) polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP). We used the PCR-RFLP on 60 parasitological confirmed CL patients who referred to leishmaniasis laboratory from the School of Public Health, Tehran University of Medical Sciences. The PCR-RFLP could correctly detect 51 Leishmania species of the 60 confirmed positive specimens, where all the other 10 parasitological (microscopy and culture) negative samples that were prepared from other bacterial- and fungal-infected lesions had negative results. The results also revealed that Leishmania major was the dominant species (53.3%). This study suggests that the PCR-RFLP assay with serosity materials punctured from CL patients using Hae III enzyme is useful for the rapid identification of Leishmania species.

Readability and information density in biomedical research

OBJECTIVE: This study was performed in order to compare the lexicosyntactic readability, and the information density in the informed consent forms used in biomedical research, in comparison with standard scientific texts dedicated to the general population. In addition, we studied whether there is a correlation between information readability and density. METHODS: Fifteen informed consent forms, 6 articles from "Sciences et Avenir" and 6 articles from "Sciences et Vie Junior" were analyzed. The lexicosyntactic readability was calculated using the Flesh score, and the information density using the number of information bits related to the number of words. RESULTS: The lexicosyntactic readability was lower in the informed consent forms (25, 17-32) compared with "Sciences et Avenir" (32, 29-38), but even higher in "Sciences et Vie Junior" (42, 38-57). Conversely, the information density was similar in "Sciences et Vie Junior" (0.24, [0.21-0.27]) and the informed consent forms (0.24, [0.22-0.26]), but higher in "Sciences et Avenir" (0.32, [0.26-0.38]). CONCLUSION: Informed consent forms are less readable, but paradoxically less dense than scientific papers dedicated to the general population. There is no correlation between density and readability.

在多孔胶原支架上构建三维工程的心肌组织

背景目前已有转化的SV40细胞系、C2C12成肌细胞、心肌细胞、骨骼肌细胞以及胚胎干细胞用于修复哺乳动物心脏的细胞移植治疗,然而细胞移植治疗对严重缺失或损伤心肌结构的治疗的作用却不大.组织工程技术为此类心肌疾病的研究及治疗提供了新的可能性,目前已有可替代和改善骨、软骨、肾、肝、神经及皮肤等组织和器官的生物合成结构物.目的探索多孔胶原作为构建三维工程心肌组织支架材料的可行性.设计非随机、对照的实验研究.地点和对象实验地点军事医学科学院生物工程研究所.动物清洁级1日龄Wistar大鼠400～500只,雌雄不限,体质量8～10 g;成年Wistar大鼠五六只,雌雄不限,体质量250 g,由军事医学科学院实验动物中心提供,饲养温度22～26℃,湿度40%～60%.干预在无菌条件下,将经胰蛋白酶消化获得的新生鼠心肌细胞分别接种于三维多孔胶原支架和培养板上,比较心肌细胞在两种培养模式的代谢差异.主要观察指标检测葡萄糖比消耗率、乳酸比产率、乳酸转化率、肌酸激酶及乳酸脱氢酶活力变化.结果培养于多孔胶原支架上的心肌细胞的代谢特性近似于心肌细胞在培养板上培养的二维生长模式.结论心肌细胞与多孔胶原支架形成了具有自律性同步收缩的三维工程心肌组织,多孔胶原作为心肌组织工程的支架材料有良好的应用前景.
