生物学的

Among the scientific community, the Big Bang, abiogenesis, and biological evolution are generally considered to be the correct de script ion of the origins of the universe and life on Earth.

在科学界中，宇宙大爆炸、自然发生和生物学进化通常被认为是宇宙和地球生命正确的描述。

The study showed the recombinant wt/mCREG protein depressed the VSMC proliferation depending on dose and the optimal concentration was 400nM;2biologic function of CREG protein and the membrance receptor mechanism:①effect on VSMC migration: the wound healing experiment showed the OB2 cells migration was slower significantly after added wt/mCREG(400Nm) in supernatant. The HITASY cells migration were very slowly and no remarkable change. The gelatinase digestion and Western blot analysis showed the matrix metalloproteinase was decreased and TIMPs was increased;②effect on differentiation: after added wt/mCREG(400nM), the expression of myocardin, SMα-actin, MHC and caldesmin were increased and that of LM-1 and FN were decreased in OB2 cells. These effects were more significant when adding wtCREG.;③effect on VSMC proliferation: Cell cycle assay and BrDU stain showed: after added the wtCREG and mCREG protein, the ratio of cell in G0/G1 phase increased to 0.5773 and 0.5572 from 0.5308 respectively in OB2 group, which increased to 0.7369 and 0.7034 respectively from 0.6297 in HITASY group;3Role of M6P/IGF2R in CREG biologic function:①ELISA and co-immunoprecipitation showed the wt/mCREG binding to M6P/IGF2R directly.②antibody blocking test: when the anti-IGF2R was added to medium at the same time with wt/mCREG at different concentration(2μg/mL、4μg/mL、8μg/mL),the effects of CREG protein which depressing proliferation, migration, secretion and promoting differentiation were blocked, which had the positive correlation to the concentration of added anti body. The studies showed two combinant CREG promoted VSMC switch to differentiation phaenotype, at the same time, depress VSMC proliferation, migration and secreting extracellular matrix.

上述实验结果证实：两种重组CREG蛋白对VSMC增殖均有剂量依赖性的抑制作用，并且相同浓度的糖基化的CREG蛋白对细胞增殖的抑制效应更为显著，最佳效应浓度为400nM；2两种重组CREG蛋白添加后对HITASY和OB2细胞生物学行为的影响：①CREG蛋白对VSMC迁移的影响：刮伤实验发现，加入最佳效应浓度的wtCREG和mCREG蛋白24h后，OB2组迁移能力下降，HITASY组无明显变化；细胞外基质金属蛋白酶-2，9(Matrix metallo-proteinase 2，9，MMP2 ，9)明胶酶电泳检测和Western blot检测结果证实，两种CREG蛋白均可以使OB2细胞合成细胞外基质MMP2，9减少，而组织金属蛋白酶抑制物(Tissue Inhibitors of Metalloproteinases，TIMPs)增加；②CREG蛋白对VSMC分化的影响：加入400nM的wtCREG和mCREG蛋白12h后，OB2细胞myocardin、SMα-actin、MHC、caldesmin表达增加，LM-1、FN表达减少；③流式细胞仪分析细胞周期和BrDU染色分析证实，加入400nM的wtCREG和mCREG蛋白后，OB2组G0/G1期细胞由0.5308分别增加至0.5773和0.5572，HITASY组G0/G1期细胞由0.6297分别增加至0.7369和0.7034；3M6P/IGF2R在重组CREG蛋白的生物学功能中的调控作用：①免疫共沉淀和免疫荧光双染色分析结果显示，CREG蛋白与M6P/IGF2R存在直接结合；②应用抗体阻断实验：将不同浓度的anti- M6P/IGF2R(2、4、8μg /mL)与两种CREG蛋白同时加入培养液中，CREG蛋白抑制VSMC增值、迁移和合成细胞外基质、促进分化的效应减弱，而且与加入anti- M6P/IGF2R浓度正相关。

ANALOGIES are often drawn between the fields of computer science and biology. The information-processing abilities of DNA are a form of natural molecular computing, and computer viruses leap from machine to machine in ways reminiscent of their disease-causing namesakes. At the International Solid-State Circuits Conference in San Francisco this week, a trio of mighty information-technology firms—Sony, Toshiba and IBM—pushed the analogy a little further. They unveiled a much anticipated new computer chip, four years in the making, the very name of which is a biological metaphor: the Cell.

人们经常把计算机科学和生物学进行类比，DNA的信息处理能力是一种自然分子的计算形式，而计算机病毒则让人想起致病性生物病毒，从一台机子感染另一台机子，而这个星期，信息技术的三巨头——索尼、东芝和IBM在旧金山召开的国际晶体管集成电路会议上，把两者间的这种类比作了进一步的推进，他们披露了一种已经研制了四年的、非常有希望的新型计算机芯片，这种芯片的名字来自生物学：细胞。

Which play a major role in the pathological changes of restenosis after angioplasty But AT2 receptor is only expressed abundantly in the fetal vasculature with rapid decline after birth and the level of re-expression in the adult vasculature after injury is very low So there are little understanding about the actions of AT2 receptor in vascular diseases, especially in the restenosis after injury.

Biological characteristics of the pathogen and the resistance of 13 cultivars of tea plant to tea brown blight were studied by means of natural infection in the field and artificial inoculation in vitro. Resistant cultivars and susceptible cultivars of tea plant were divided. And the resistance mechanism was researched tentatively. The findings are as follows: 1 Some biological characteristics of the pathogenic fungus The experiment result showed: the optimum temperature for the growth of fungus mycelium was from 24 to 27℃, the optimum temperature for sporulation ranged 22 to 30℃. Treated at 54℃ in 10 minutes, the spores didn't germinate. The optimum pH for the growth of the mycelium was 5.1～5.9, the optimum pH for sporulation ranged 5.0～6.0. Light had no much effect on the growth of fungus mycelium, but had much effect on the reproduction of the spore.
