衰退的

Further comparison of the vascular bundle sheath sclerenchyma cell deterioration in separate plants infected with an additional four CTV isolates, CTV-2, T-TX8, T-TX9 and T-TX24 showed that there were significant differences in scleranchyma cell deterioration in principal lateral vein, midvein, petiole, and healthy control with all four CTV isolates (P=0.000 1, F=80.60, df= 47). Healthy plants had no such sclerenchyma cell deterioration.

CTV-2、T-TX8、T-TX9 、T-TX24等另外4个柑橘速衰病毒株系分别侵染后，主支脉、中脉、叶柄维管束鞘厚壁细胞的衰退与对照差异显著(P=0.000 1， F=80.60， df= 4，7)，健康植株厚壁细胞没有退化。

A second factor is the global nature of the downturn.

To investigate this hypothesis, the researchers carried out a randomized, controlled trial in 563 patients with mild to moderate AD, comparing treatment with the growth hormone secretagogue MK-677, also known as ibutamoren mesylate, which is a potent inducer of IGF-1, with placebo.

作者写道，IGF-1与生长激素及生长激素相关荷尔蒙组成体促素轴，这三种都和年纪衰退有关；AD病患的IGF-1值比年龄相仿者低，他们指出，在老鼠研究中，血清IGF-1被发现可以藉由增加清除而调节乙型淀粉样蛋白。
