Synaptic Plasticity in Mouse Models of Autism Spectrum Disorders

Analysis of synaptic plasticity together with behavioral and molecular studies have become a popular approach to model autism spectrum disorders in order to gain insight into the pathosphysiological mechanisms and to find therapeutic targets. Abnormalities of specific types of synaptic plasticity have been revealed in numerous genetically modified mice that have molecular construct validity to human autism spectrum disorders. Constrained by the feasibility of technique, the common regions analyzed in most studies are hippocampus and visual cortex. The relevance of the synaptic defects in these regions to the behavioral abnormalities of autistic like behaviors is still a subject of debate. Because the exact regions or circuits responsible for the core features of autistic behaviors in humans are still poorly understood, investigation using region-specific conditional mutant mice may help to provide the insight into the neuroanatomical basis of autism in the future.     

四种牙本质粘结剂粘结强度的比较研究

目的 比较四种牙本质粘结剂(I-Bond、G-Bond、Xeno V和Clearfil S3 Bond)的粘接强度,为临床上正确选择、合理使用粘接剂提供实验依据.方法 60颗离体前磨牙,随机分为4组,每组15颗.将四种粘结剂分别用于暴露的牙本质表面,修复树脂“冠”,光照固化.用CMT7104型万能材料测试仪测试试件微拉伸和剪切粘结强度,比较四种牙本质粘结剂的粘结强度.结果 四种粘结剂的粘结强度均值依次为Xeno V＞Clearfil S3 Bond＞G-Bond＞I-Bond.其中,I-Bond与G-Bond的粘结强度差异无显著性(P＞0.05);Xeno V和Clearfil S3 Bond的粘结强度差异亦无显著性(P＞0.05);而I-Bond和G-Bond的粘结强度明显低于XenoV和Clearfil S3 Bond (P＜0.05).结论 四种牙本质粘结剂中,Xeno V和Clearfil S3 Bond的粘结强度明显高于I-Bond和G-Bond的粘结强度.     

Highlights from the 8th World Congress on Peritoneal Surface Malignancies

The 8th World Congress on Peritoneal Surface Malignancies was held in Berlin,Germany from October 31,2012 to November 2,2012,in which more than 571 delegates from 56 countries attended.This conference covered a variety of topics on peritoneal carcinomatosis(PC) from gastric, colorectal,and ovarian cancers,as well as pseudomyxoma peritonei,malignant peritoneal mesothelioma,and abdominal sarcoma.PC experts across the world presented the most upto -date results of their basic and translational studies as well as clinical trials.In particular,the following research interests were highlighted.
