Due to the deficiency of cyclin B1 and 〓, spermatogonia and pachytene/diplotene primary spermatocytes in contralateral cryptorchid testis were unable to form MPF, and therefore, they could not accomplish their nuclear division, and became arrested at the transition stage from mitosis to meiosis (G2/M phase). We also found that testosterone could regulate the cyclin B1 expression in spermatogenic cells.

由于cyclin B1和〓的缺失，粗线期/双线期初级精母细胞中的MPF无望形成，从而导致生精细胞分裂停滞在由有丝分裂向减数分裂过渡的G2/M相；（5）睾酮可在翻译水平上调控阴囊内睾丸生精细胞cyclin B1蛋白的表达。

Results: The incidence of cryptorchidism of male offsprings in group C and D was 10.8% and 63.5% respectively. The organ/weight of cryptorchid testis and epididymis significantly decreased compared with the control. Abnormal pathological and micro-structural alternations of seminiferous epithelium and sertoli cells were also observed.

结果：C、D组雄仔鼠隐睾发生率为10.8%和63.5%；隐睾睾丸、附睾的脏器系数显著减轻；睾丸生精上皮萎缩，生精细胞层减少甚至消失，曲精小管体积减小；同时附睾管腔中精子缺如。

It was a new mousegene in GenBank and named as SRG-L(spermatogenesis related gene expressed in the latestages of spermatogenic cells). The sequence of this cDNA has been deposited in GenBankwith the Accession No. AY352586. 2. Analyses of expression characteristics of SRG-L during mouse spermatogenesis.The results of RT-PCR and Northern Blotting indicated that no expression signal of thisgene could be observed in primitive type A spermatogonia and type B spermatogonia. Asignal first appeared in diplotene/pachytene spermatocytes, and was significantlyintensified in round spermatids and elongating spermatids, findly went down to beundetectable in mature spermatozoa.

RT-PCR和Northern Blotting分析表明：该基因在早期A型和B型精原细胞中不表达，从双线期初级精母细胞阶段开始表达并逐渐上调，在粗线期初级精母细胞、圆形精子细胞及长形精子细胞中均检测到高水平的mRNA，但在成熟精子中消失，具有明显的阶段特异性表达特征，并且组织特异性表达分析显示该基因在睾丸组织中的呈高表达。

Citrus essential oil also can be stored 1-2 years, with a dripper bottle packaging with the product is generally between 3%-10% dilution of essential oils, not pure essential oils.

柑橘类精油也可保存1-2年，用配有滴头的瓶子包装的产品一般是3%-10%之间的稀释精油，不是纯精油。

To create your own salt scrub, mix two cups of sea salt or Epsom salt with one teaspoon each of essential oil of lavender, spearmint and eucalyptus and six tablespoons of almond oil.

去制造你自己的盐洗剂，用两杯海盐或者 Epsom 盐，与各一茶匙的薰衣草精油、薄荷精油和按树精油，及六茶匙杏仁油混合。

Face detergent and softening milk with pure sweet almond vegetable oil, equisetum plant extract, pure essential oils of ylang-ylang, geranium and lavender*, green clay gel and pure spring water.

We presents an accurate F method based on corresponding point adjustment.The method adjusts coresponding points according to the fixedness of projective transformed cross ratio,then calculates F matrix accurately through linear and non-linear methods. When computing intrinsic parameter,A matrix,we simplify the step,and stress on the two important parameters of A.The result will be getten through solving Kruppa equation based on SVD decomposition.In order to compute extrinsic parameters,we use linear method to get initial R and t,then apply non-linear method to accurate them.

提出了基于匹配点调整的F求精方法，先根据摄影交比不见性对手工选择的匹配点进行调整，再用线性、非线性结合的方法求精F矩阵；在计算内部参数A中，进行了一定的简化，把重心放在A中重要的两个参数上，用SVD分解法计算Kruppa方程；在计算外部参数时，首先用线性法求解R、t，然后再用非线性法迭代求精。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
