Saber se tortura e terrorismo são crimes iguais provoca a divisão de opinião dos parlamentares. A Comissão de Sistematização coloca apenas a tortura como crime inafiançável, imprescritível e sem direito à anistia. O substituto do Centrão inclui neste parágrafo também o terrorismo. Este parágrafo deve ser resolvido pelo voto. A emenda que define o racismo como crime inafiançável e sem direito de anistia foi aprovada por 518 e 3 contra. O livre exercício de crença deverá ser votado ainda hoje. Enquanto se discute o primeiro capítulo, os constituintes buscam o acordo no capítulo seguinte, que trata dos direitos sociais dos brasileiros.

Teeth of 71 estuarine dolphins (Sotalia guianensis) incidentally caught on the coast of Paraná State, southern Brazil, were used to estimate age. The oldest male and female dolphins were 29 and 30 years, respectively. The mean distance from the neonatal line to the end of the first growth layer group (GLG) was 622.4 ±19.1 μm (n=48). One or two accessory layers were observed between the neonatal line and the end of the first GLG. One of the accessory layers, which was not always present, was located at a mean of 248.9 ±32.6 μm (n=25) from the neonatal line, and its interpretation remains uncertain.The other layer, located at a mean of 419.6 ±44.6 μm (n=54) from the neonatal line, was always present and was first observed between 6.7 and 10.3 months of age. This accessory layer could be a record of weaning in this dolphin. Although no differences in age estimates were observed between teeth sectioned in the anterior-posterior and buccal-lingual planes, we recommend sectioning the teeth in the buccal-lingual plane in order to obtain on-center sections more easily. We also recommend not using teeth from the most anterior part of the mandibles for age estimation. The number of GLGs counted in those teeth was 50% less than the number of GLGs counted in the teeth from the median part of the mandible of the same animal. Although no significant difference (P>0.05) was found between the total lengths of adult male and female estuarine dolphins, we observed that males exhibited a second growth spurt around five years of age. This growth spurt would require that separate growth curves be calculated for the sexes. The asymptotic length (TL∞), k, and t0 obtained by the von Bertalanffy growth model were 177.3 cm, 0.66, and –1.23, respectively, for females and 159.6 cm, 2.02, and –0.38, respectively, for males up to five years, and 186.4 cm, 0.53 and –1.40, respectively, for males older than five years. The total weight (TW)/total length (TL) equations obtained for male and female estuarine dolphins were TW = 3.156 × 10−6 × TL 3.2836 (r=0.96), and TW = 8.974 × 10−5 × TL 2.6182 (r=0.95), respectively.

对两种不同基因型小麦京411(北京地区高产小麦品种)和小偃54(在生产上已应用二十年的优良品种)幼苗及旗叶光抑制特性进行了比较研究,着重探讨了它们抗光氧化的差异及其机理,主要结果如下: 1. 强光条件下,同京411相比小偃54能保持较高的光合色素含量和放氧速率。其DCPIP光还原活性也较高。 2. 光谱特性分析表明,强光胁迫下小偃54在红区及蓝区的特征性吸收峰及F683荧光发射峰下降的幅度明显小于京411相应峰位的下降。 3. 色素蛋白复合物分析表明,强光条件下,京411色素蛋白复合物中LHCII聚合体大量的解聚,而小偃54在强光条件下仍能保持较高比例的LHCII聚合体。这可能在一定的程度上有利于小偃54在强光下维持较强的激发能耗散的能力。 4. 多肽SDS-PAGE分析表明,强光对不同基因型小麦中同PSII光抑制敏感性有关的两个外周蛋白23kD和17kD的影响不同。光抑制明显地降低了京411的23kD和17kD的含量,而对于小偃54中这两个外周蛋白23kD和17kD的影响不大。强光条件下小偃54旗叶PSII颗粒中捕光色素蛋白27kD含量提高,而京411捕光色素蛋白27kD含量明显的下降。 5. 上述结果表明,西北地区的优良小麦品种小偃54同北京地区的高产品种京411相比更耐强光的胁迫,其抗光氧化的能力较强。 6. 进一步分析表明,同京411相比,小偃54抗光氧化的主要原因是其不仅含有较大的叶黄素循环的色素库,而且在强光下能维持高的VDE酶活性及高水平的叶黄素循环的脱环化水平。 7. 叶黄素循环色素在两个小麦品种类囊体膜色素蛋白复合体中的分布存在差异,抗光氧化的小偃54大部分的VAZ分布在PSII上,其中绝大部分集中在LHCII聚合体上。LHCII上VAZ的集中分布可能有利于在强光下对过多光能的耗散,减少过多激发能对PSII的损伤。 8. 类囊体膜流动性分析表明,叶黄素循环参与了对类囊体膜流动性的调整,对维持强光下抗光氧化品种小偃54的类囊体膜相对稳定起重要作用。 9. 依赖于叶黄素循环的热耗散是抗光氧化品种小偃54的一个主要的光保护途径。
