GABA Transporter-1 Activity Modulates Hippocampal Theta Oscillation and Theta Burst Stimulation-Induced Long-Term Potentiation

The network oscillation and synaptic plasticity are known to be regulated by GABAergic inhibition, but how they are affected by changes in the GABA transporter activity remains unclear. Here we show that in the CA1 region of mouse hippocampus, pharmacolog

粪便收集时间和饲料中肉骨粉含量对异育银鲫(Carassius auratus gibelio)消化率的影响(英文)

本研究探讨了通过收集器不同粪便收集时间和饲料中肉骨粉( MBM)含量对异育银鲫干物质、蛋白、能量、磷的表观消化率(ADC)影响。不同梯度(0 ,20 ,40 ,60 ,80 ,100 %)的肉骨粉替代鱼粉(FM)蛋白配制成六种等氮(粗蛋白:410 g/kg)等能(总能:18 kJ/g)的饲料,通过11周的饲养实验,实验开始后2周开始收集粪便,收集时间分别是:排粪后1 min,投喂后4h和16h。结果表明,干物质、蛋白、能量、磷的消化率明显随粪便收集时间增加而升高(p<0 .05) ,但在高肉骨粉替代饲料中
