By comprehensive and detailed measurement of the time course of withdrawal signs in rats, Joyce et al. (J. Theo. Biol. 240:531-537, 2006) recently provided a creative quantitative model of the onset of drug dependence based on the requirement of protein synthesis. Because the initial model fit the data imperfectly over the full time course, those authors postulated that additional features would be needed. We report excellent fit of the data (R(2)=0.96) by adding: (1) a transient early phase, and (2) a delay in the buildup of protein.
通过对大鼠戒断症状时间进程进行全面而详细的测量,乔伊斯等人(《理论生物学杂志》240:531 - 537,2006年)最近基于蛋白质合成的需求,提供了一个关于药物依赖发作的创新性定量模型。由于最初的模型在整个时间进程中对数据的拟合并不完美,这些作者推测还需要其他特征。我们通过增加以下内容报告了对数据的出色拟合(R² = 0.96):(1)一个短暂的早期阶段,以及(2)蛋白质积累的延迟。
