Under imitated daily field microclimatic conditions for heat stress, the rice cultivar "Jinyou63"(which is a hybrid rice combination) was treated with a consecutive 3-day heat stress during meiosis in phytotron. Anther and pollen tissues at different development stages after subjected to heat stress were sampled and analyzed for transverse abnormalities.

本研究模拟田间典型灾害天气条件，在人工气候箱内对杂交水稻&金优63&花粉母细胞减数分裂期进行连续3 d的热害胁迫处理，对处理后不同发育时期的花药组织取样切片观察，从组织、细胞水平探讨水稻受高温胁迫后花药可能出现的早期异常特征。

We discuss a series of 11 patients seen at the Cole Eye Institute with the condition of myelinated retinal nerve fibers, myopia, and amblyopia and describe the clinical characteristics.

我们讨论了 Cole 眼科中心11例视网膜有髓神经纤维，近视和弱视的病人的临床特征。3名病人已经有视神经发育异常，并对相关文献进行了综述。

Lipid peroxidation would cause the deficiency of myelinogenesis, Dysfunction of synaptic conduction and developmental anomaly of nerve cell if the deficiency of completely.

当硒缺乏时，硒蛋白活性降低，清除H2O2能力减弱，脂质过氧化导致髓鞘形成不良，突触传导障碍，神经元发育异常，造成严重的脑功能紊乱。

Recently, the gene responsible for nevoid basal cell carcinoma syndrome, an autosomal dominant disorder characterized by multiple malformations and susceptibility to a variety of tumors and, particularly, to BCC, has recently been identified as PTCH.

痣样基底细胞癌症候群是一种体染色体显性遗传疾病，其主要表现有基底细胞癌、成齿的角质囊肿和其他多种骨骼发育异常，这个疾病被认为和PTCH基因突变有关。

In conclusion, these results suggested that (1) the ageing-associated decline in fertility of female KM mouse was due to a decrease in both quantity and quality of oocytes;(2) the ooplasm from young mice did not correct the meiotic errors of aged mice, and the ooplasm from aged mice did not induce abnormal segregation of meiotic chromosome of young mice, indicating that meiotic anomalies found in the oocytes of aged mice might be related to nucleus or chromosomes and relevant factors;(3) a critical nucleocytoplasmic ratio was essential for normal maturation and segregation of meiotic chromosomes of oocytes and development to 2-cell embryos.

本研究结果表明：（1）昆明白小鼠与衰老相关的生育力下降是其卵母细胞数量减少和质量下降的综合结果；（2）年轻小鼠卵母细胞细胞质不能纠正老龄小鼠GV的减数分裂错误，老龄小鼠卵母细胞细胞质也不诱导年轻小鼠的GV发生减数分裂错误，老龄小鼠卵母细胞减数分裂异常很可能与细胞核或染色体及其相关因素有关；（3）关键的核质比对卵母细胞正常的成熟、减数分裂染色体分离及2-细胞期胚的发育是绝对必需的。

Individuals with one X and no Y chromosome are phenotypically females but have a group of physical abnormalities including dwarfism and failure of ovarian development known as Turner's syndrome.

含有一个X而无Y染色体的患者表型为女性，但有一组机体异常表现，包括侏儒郑和卵巢不发育，称为Turner综合症。

Stone fruit trees can not set fruits when abnormal germ development occurs; while pomaceous fruit trees can set fruits without seeds, but the pulp cells grow very slow.

核果类果树在胚芽发育异常时不能坐果。仁果类果树在没有种子时可以坐果，但果肉细胞生长缓慢。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
