采用高脂饮食(high fat diet,HFD)诱导的肥胖大鼠模型,探究口服胡椒碱(1-piperoylpiperidine,PIP)对代谢紊乱引发生物钟异常的调控作用。结果表明,PIP减轻了HFD诱导的肝脏损伤,降低了血脂水平,缓解了肝脏生物钟和脂代谢基因的昼夜节律紊乱,恢复了与生物钟密切相关的脂质分子溶血磷脂酸(16:0_18:1)、双甲基磷脂酸(38:8e)、磷脂酰乙醇胺(16:0p_22:6)和甲基磷胆碱(32:4e)的表达水平变化。本研究结果可为PIP调节肝脏脂代谢昼夜节律提供一定的理论依据。

从中国种植的约800万公顷杂交水稻,从研究文献以及这从次学术讨论会上提交的论文,都充分地证明了水稻存在杂种优势。热带与温带地区异质的杂种F1产量每公顷约10吨。在有利条件下,产量表现出20—30％的杂种优势,但热带季节变化很大;在较低温度下,杂种具有较低的产量优势。杂种F1的产量优势主要地是由于增加了小穗数与较大的粒重。在相对低的氮水平下,杂种F1的产量潜力高于常规育种的半矮秆品种。有关基因作用与配合力的报导表明,水稻的一般配合力与特殊配合力两种效应都是重要的。一般配合力的效应往往大于特殊配合力的效应,但存在充分的例外,因此,应进一步利用杂种。
