郏县大尾寒羊产肉性能配套技术研究

在调查研究的基础上,对郏县大尾寒羊进行了配套技术研究。经数据处理和屠宰分析,初生重、断奶重、6月龄活重等群体平均数与对照组的3个群体平均数之间存在着极显著的差异,即初生重提高20.3％,断奶重提高11.32％,6月龄活重提高11.10％,同时屠宰率、净肉率也分别提高了1.48％和1.72％,出栏期由原来的270天缩短到18O天(习惯是9～11个月出栏)。出栏率郏县也有明显的提高。

Cognitive improvement following transvenous adipose-derived mesenchymal stem cell transplantation in a rat model of traumatic brain injury

The effects of adipose-derived mesenchymal stem cell (ADMSC) transplantation for the repair of traumatic brain injury remain poorly understood. The present study observed neurological functional changes in a rat model of traumatic brain injury following ADMSC transplantation via the tail vein. Cell transplants were observed in injured cerebral cortex, and expression of brain-derived nerve growth factor was significantly increased in the injured hippocampus following transplantation. Results demonstrated that transvenous ADMSC transplants migrated to the injured cerebral cortex and significantly improved cognitive function.
