Moreover, the A-B-A triblock copolymer solution in a selective solvent, which is good for the block B, was explored. It was observed that the flowerlike micelles were formed, in which the central block B took on a loop conformation and the two end A blocks became a part of the micellar core. It was found that some of the soluble middle B blocks served as extended bridges between the small clusters by the poorly solvated end A blocks.

在A-B-A三嵌段共聚物溶液体系中,溶剂是链段B的良溶剂,是链段A的不良溶剂,此时我们得到了花型结构的胶束,其中花心是由链段A聚集而成,花瓣是由链段B形成的,而且在体系中也发现了有些胶束间存在着桥,并且在浓度很高时,体系出现了凝胶现象。

The growth of H. fusiformis was determined by weighting the fresh algae every two days and the photosynthetic oxygen evolution was assayed by a Clark-type oxygen electrode. To determine the contents of chlorophyll a and UV-absorbing compounds, methanol extracts from H. fusiformis were scanned from 250 to 750 nm. The concentration of chlorophyll a was calculated using the equation of Porra and the contents of UVAC per fresh mass were estimated by determining the ratio of UVAC to chlorophyll a according to Dunlap et al and multiplying the ratio of chlorophyll a content to fresh weight of the sample used.

羊栖菜的生长是通过每两天测量一次藻体的湿重来测定的,光合放氧是用Clark型氧电极测定的,为了测定藻体叶绿素a和紫外吸收物质的含量,从250 nm到750 nm对羊栖菜的甲醇提取液进行扫描,叶绿素a的浓度用Porra的公式计算,紫外吸收物质的计算是根据Dunlap的方法先计算紫外吸收物质和叶绿素a的比率,然后乘以每单位藻体叶绿素a的含量。

CaN Aβ gene silencing can reduce myocardial hypertrophy in cultured cells, si1280 (21bp) of CaN Aβ gene is the most effective target site for siRNA. The method of intrapericardial injection of plasmid, microbubbles and erzymes can improve transfection efficiency of non-viral plasmid with satisfying targeted transfection. But the scope of transfected myocytes is still limited. CaN Aβ shRNA expressing plasmid transfection in vivo by pericardial injection results in decreased CaN Aβ protein expression of small part of myocytes, and CaN Aβ mRNA only shows decreased trend. The dosage of non-viral vector and the parameters of ultrasound energy should be optimized in further study.

In Wistar rats, latent period of a-wave in scotopic rod response after 1-week transplantation was shorten (P.05); and latent period of a-wave in scotopic rod response after 2-week transplantation was prolonged (P.05); while latent period of b-wave in scotopic maximum response after 1-week transplantation was shorten (P.05). In RCS rats, amplitude of a-wave in scotopic rod response and photopic response after 4-week transplantation was increased (PO.05); while latent period of a-wave in scotopic rod response after 4-week transplantation was shorten (PO.05).Conclusion 1. At the age of 3 months, photoreceptors of the RCS rat degenerated completely, which leaded to the reduction of amplitudes of a-wave and b-wave.

利用英国PP-SYSTEM公司生产的TPS-1便携式光合作用测定系统,对3个树莓品种的光合特性进行了比较研究,结果表明树莓叶片光合速率日变化呈双峰曲线,A品种&日中低落&现象明显,B、C品种不甚明显;B、C品种的蒸腾速率日变化曲线基本上为双峰型,日变化过程中的&午休&现象非常明显,而A品种为单峰型,日变化过程中的&午休&现象不甚明显;此外,叶片气孔导度与叶片光合速率的日变化趋势基本一致,呈平行变化趋势,说明气孔导度是影响光合速率的直接因子;较B、C品种而言,A品种具有较高的水分利用效率,说明其更能节约并有效地利用土壤水分。

In a word, mass! Recently undeliberated NB was popular, like old saying of making all clear without mention a word, using Beijing dialect it's much easier --"B-Pretending", represented by part small star blogs and strange name blogs, more over the writing is, the better it can up to people's demands, just like Taiwan entertainment programs, but it cannot be formal, as it's not necessary to collect and publish a book. Talk about Taiwan entertainment programs I had to mention Jacky Wu, this man who was characterized by A use his own power saved many programs, and it's really funny. Recently I always view "People in the Pan", it stands for another Taiwan entertainment character -- imitation, it makes me laughing a lot, and I can refer a sentence from Dong Lu's blog "If Li Yong comes to Taiwan he must lose his job." Fortunately ordinary family cannot see these Taiwan TV Stations, or CCTV cannot defend its market share, in fact it's forced by a loose competitive atmosphere, the fact that Hunan TV is so hot now in China reminds me what an ancester said: a kid became famous only because of there is no hero in world.

这两 年流行的网络文字是不经意间的NB,就像古话说得&不着一字尽得风流&,拿北京话说就简单多了叫&装B&,以部分小明星的博和名字怪异的为代表,文字越潇洒或者越俗越能迎合大家的需求,就像台湾的娱乐节目,不过上不了台面,如果硬要出个书什么的我看大可不必,说起台湾娱乐节目,不能不提吴宗宪,这个活跃舞台几十年的以A为特点的全才中年男子以一己之力养活了很多节目,而且确实很好笑,最近我看的比较多的是全民大闷锅,代表台湾娱乐的又一大特点--模仿,常常能让我前仰后合,不由想到董路 BLOG上的一句话,&如果让李咏去台湾肯定会失业&,还好现在台湾的这些台普通家庭还看不到,不然CCTV一定招架不住,其实说白了都是一个宽松的竞争环境逼的,湖南卫视现在在大陆这么火,让我想到一句话:世无英雄,遂使竖子成名。

By comparing with known compound A2'P 5'A,it was shown that two ribose rings of a and b adopt predominantly S conformation at 18℃, but with elevation of temperature, the N conformation of some ribose ring increaed: the torsional angles e' and β of the phosphate backbone were estimated to have a change of +2° and ±12°respectively; two ribose rings of both A2'P(CH3)5'A and were partially overlapped and the degree of overlapping of was smaller than that of the : with increasing of temperature, the adenine moiety of A2'P(CH3)5'A showed a stronger tendency to unstack than A2'P(CH3)5'A .

它们与A2′P5′A相比发现:(1)在18℃时两个核糖环是S型构象占主要成分,但随温度升高有的核糖环趋向于转化成N型构象;(2)磷酸骨架的扭角ε′和β分别改变±2°及±12°;(3)A2′P(CH_3)5′A和的两个核糖环均属部分重叠,并且前者的重叠程度小于后者;(4)随着温度升高,A2′P(CH_3)5′A比A2′P(CH_3)5′A有着更强的去堆积效应。

There was a good correlation between Ptw,AVCtw,MVOtw,PTV,PUV,UntwR and age.2.Assessment of left ventricular twisting and untwisting of DCM patients19 DCM patients(range 18-80 yr,mean age 50.52±17.52 yr,2 females) and 21 age- and sex-matched normal controls(range18-80 yr,mean age 49.05±16.94 yr,5 females) were enrolled into this study.Then DCM patients were divided into two groups:E/A<2 group and E/A>2 group.The routine echo showed the left ventricle dilated and EF decreased.The results show that LV rotation degree, rotation velocity at baseline and apex were irregular changeable with the cardiac cycle;the rotation direction was clockwise at the base and counterclockwise at the apex,and are combined to yield a systolic counterclockwise twisting as seen from the apex,but the rotation at the basal and apex were the same direction in some patients.

扩心病患者左室扭转及解旋特征的研究选择扩张型心肌病(Dilated Cardiomyopathy,DCM)组患者19例(男性17例,女性2例,年龄18~82岁,平均50.52±17.52岁),健康体检者21例(男性16例,女性5例,年龄18~80岁,平均49.05±16.94岁)作为对照组,扩心病患者按照E/A分为E/A<2、E/A>2两个亚组,结果显示:常规超声显示DCM组LVDd值增大,EF值减小;DCM患者左室心底部与心尖部心肌旋转角度、旋转速度随心动周期变化曲线明显紊乱;与正常组比较,DCM患者左室整体扭转角度和速度分别为(6.49±1.82)°、(67.84±15.60)°/s,较正常人显著减低P<0.01左室舒张末及收缩末扭转角度DCM患者较正常人显著减低(P<0.01,左室舒张末及收缩末时间在DCM-E/A>2组较正常人及DCM-E/A<2组显著缩短P<0.01DCM患者左室解旋速度较正常人亦显著减低(P<0.01,左室功能轻中度减低(DCM-E/A<2)患者解旋率[(0.29±0.07)%]较正常人[(0.42±0.11)%]明显减低,但当左室功能重度减低(DCM-E/A>2)时左室解旋率[(0.63±0.35)%]较正常人反而增加;左室整体扭转角度、舒张末扭转角度、收缩末扭转角度、解旋与左室射血分数未见明显相关性。3。
