American Journal of Plant Sciences 2022年第4期13卷 494-505页

The presence and distribution of Citrus tristeza virus (CTV) strains on plants of four citrus species required analysis of plants showing small fruits, yellowing, and twig dieback. Typical citrus tristeza symptoms showed in citrus plantations in Veracruz, Mexico, and caused gradual deterioration, low yield, and death of the plants. Seven citrus-growing municipalities in Central and northern Veracruz presented the severe VT strain: the incidence in seven of the eight sampled municipalities ranged from 7% in Alamo to 50% in Tihuatlan. As for the T30 strain, its presence and distribution ranged from 17% in Tihuatlan to 83% in Cuitlahuac. Values for the T3 strain went from 20% in Castillo de Teayo to 50% in Papantla. In Tihuatlan, two samples were positive for the T36 strain. Only Citrus sinensis has historical recording infections by severe strains of CTV, unlike other important citrus species. The incidence of orchards quickly declining increases rapidly in Veracruz, the largest citrus producer in Mexico. It becomes critical as the predominant and sensitive rootstock is sour orange (Citrus aurantium). It is important to note that the specific primers used could not be identified in 29% of the samples, suggesting that they could be other than T30, T3, VT, and T36 strains.

本论文试图探讨个人的体格如何深刻影响生活的各个方面,以至于作为绘画的基本条件。绘画的物理条件如何成为画家身体状况的延伸,反之亦然。身体的姿势主导绘画的过程;眼、头、脊、手的姿势产生改变,握笔姿势也随之变化,而这将得到完全不一样的绘画结果。论文的核心在于探讨,绘画者如何通过其身体运动,作为一种修行的训练。绘画,同时也是描绘人的内在情绪和心境。

在神经变性疾病患者的脑内神经元内包含体中，神经原纤维缠结（nFTs）是最常见的，它可能介导了神经元的死亡和认知障碍。本研究作者发现表达可抑制的人tau变异型的小鼠产生了进行性年龄相关的神经原纤维缠结（nFTs）、神经元丧失以及行为缺陷。抑制转基因tau后，记忆功能恢复，神经元数目稳定。但令人吃惊的是，这时神经原纤维缠结（nFTs）依然累积。这样来看，神经原纤维缠结（nFTs）不足于导致此种病理模型的认知衰减或神经元死亡。
