开始衰老

One reason why primates have not been the subject of anti-ageing studies until now is that they live so long anyway.

直到最近才开始用灵长类作为抗衰老研究的对象，原因之一是，灵长类寿命相当长。

We believe that Dollagen is so fundamental to your bodys health, and well-being, that every beauty and anti-ageing strategy should begin with collagen.

咱们认为，胶原蛋白是你的身体美容健康的福祉，是每一个美容和抗衰老的策略应该从胶原蛋白开始。

As the growth of the age, be in after achieving autumn, all sorts of structures of human body and function begin constant change, the consenescence on this kind of physiology can happen in each place of the body.

随着年龄的增长，在达到成熟期以后，人体的各种结构和功能就开始不断的变化，这种生理上的衰老在身体的各个部位都会发生。

From 200 to 400 m of the river, the proportion of over-mature forests and effete forests with trees of crown density between 50% and 75% and lower vitality begins to increase.

在200-400m的范围内，疏失度为50%-75%的长势较差的过熟林和衰老林的比例开始增多。

The techniques of the midface rejuvenation develop with the understanding of the aging appearance and the development of the facial anatomy. The earliest form of rhytidectomy only removed a piece of redundant skin, but failed to achieve significant long-term benefit. To achieve a more durable benefit, numerous adaptations of face-lift techniques are devised, including SMAS face-lift, malar fat elevation and extended supraplastysmal plane face lift. The subperiosteal approach was firstly performed in 1980s. Youthful curve was detailed by Little William in 2000. To obtain the architectural ogee, the approach of volumetric sculpture, also named three-dimensional rejuvenation, was described.

随着整形美容外科医生对面部衰老变化的认识和面部解剖学的发展，中面部年轻化手术也随之发生着演变：最初的面部除皱术只是单纯去除松弛的皮肤，但术后远期效果不理想；为获得更加持久的效果，到20世纪70年代开始了一系列面部提升术，包括：各种SMAS提升术、颧脂肪垫提升术，扩大的颈阔肌上面部提升术；到20世纪80年代后期，学者提出为获得和谐的面部容貌应进行骨膜下面部除皱术；而到21世纪初Little William提出了"青春曲线"的概念，并实施了容量雕刻技术，即三维中面部年轻化手术。

As I've aged, I've become kinder to myself, and less critical of myself.

随着一天天的衰老，我开始学会对自己好一些，而对自己的挑剔少一些。

Results一. Culturing and identification of human conjunctiva cells1. morphous of conjunctiva cellsCells were harvested by tissue cultivation after digestion. Ponderosus cells adhered after 48 hours. Cells were shown in shape of round, ellipse and polygon. Cell body was loose and lucency with nucleus in center, cell membrane was also clearly seen. Cells were arranged in inlay and fuse in film after 12-14 days.2. Immunochemistry testNomogeneous immunochernical positive granules against CK13 were observed in endochylema of human conjunctiva cells.3. growth curve of conjunctival cellsSubcultured cells were aged and feeble after 5th passage.

结果一、正常人结膜细胞的培养与鉴定1、活体细胞的形态消化后组织块培养法：48小时后见大量上皮细胞贴壁，细胞不规则呈圆形、椭圆形、多边形，细胞体肥大透亮，细胞核位于中央，胞膜清楚，约12-14天后细胞呈镶嵌状排列，融合成膜状。2、免疫组化鉴定培养的人结膜上皮细胞CK13免疫组化染色见阳性颗粒均匀分布于胞浆中。3、培养结膜细胞生长曲线传代培养多数样本于P5代以后开始出现衰老征象。

METHODS: D-galactose (1 000 mg·k-1·d-1 ) was injected into mice hypodermically for 8 weeks to induce aging animal model, and Vit-E (100 mg·kg-1; 250 mg·kg-1) was administered for 6 weeks by ig at the 3rd week of making model. After Vit-E treatment for 8 weeks, water maze test was used to determine the ability of mice's learning and memory. The activities of glutathione peroxidase and succinate dehydrogenase, the content of nitric oxide and activity of nitric oxide synthase in the brain tissue were detected separately.

小鼠连续皮下注射D-半乳糖（1 000 mg·k-1·d-1）8周制备衰老模型，并于第3周开始给予维生素E（100 mg· kg-1；250 mg· kg-1）处理；8周后采用水迷宫测定小鼠学习记忆能力，并取脑组织测定谷胱甘肽过氧化物酶和琥珀酸脱氢酶活性，测定一氧化氮含量和一氧化氮合酶活性。

At more than 400 metres, the density of Populus euphratica begins to drop dramatically.

在离河道200~400 m，树冠疏失度为50%~75%长势较差的过熟林、衰老林比例开始增多。

As we age, our fat cells in that third layer of skin thin out and get a little bumpier.

在衰老的过程中，我们的皮肤下第三层的脂肪细胞开始变薄，并有点高低不平。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
