miRNA在儿童持续性脑震荡后综合征唾液中的表达(摘译)

在美国,每年有高达两百万的儿童受脑震荡影响,约1/3会发展为持续性脑震荡后综合征(persistent post-concussion syndrome,PPCS),影响时长达数月。相较于未发生PPCS的儿童,该群体更有可能缺课、情绪低落、缺乏社交以及拥有低生活质量。目前预测PPCS风险主要依赖于患者报告的症状和临床体征。

Responses of Drought-Resistant Mutant vem1 to Stress and Cloning of VEM1 Gene in Arabidopsis

[ Objective] This study aimed to investigate the responses of drought-resistant mutant veml to stress and clone VEM1 gene in Arabidopsis. [ Method] A drought-resistant mutant veml was isolated from the Arabidops/s mutant pool. The germination rates of wild-type （WT） and mutant veml were detected to investigate the responses of mutant veml to mannitol, NaCl and ABA stress. [ Result] The mutant veml was resistant to mannitol and NaC1 stress but sensitive to ABA stress. VEM1 gene was cloned by Tail-PCR technology and sequenced. The sequencing result was submitted to NCBI for sequence alignment and gene mapping using BLAST. Database analysis suggested that VEM1 gene was a transposable clement gene. [ Conclusion] This study laid the foundation for functional analysis of drought-resistant gene VEM1.
