查询词典 osmotic pressure

To determine whether F3, similar to other large DNA iruses, encoded proteins that lock or delay apoptosis, mock- and F3-infected FHM cells were osmotically shocked and assayed for DNA fragmentation 3 hours later. NA fragmentation was clearly seen whether or not shocked cells were preiously infected with F3, indicating that infection with F3 did not block apoptosis induced by osmotic shock in FHM cells.

为了证明F3是否象其大DNA病毒一样编码能阻止或延迟凋亡的蛋白，在模拟感染和正常感染的FHM细胞被渗透压休克后3小时检测DNA片段化；结果显示无论是否休克F3感染都能诱导FHM细胞的DNA片段化，渗透压休克并不能阻止细胞凋亡。

This conclusion is based on three groups of experiments with detached root tips of wheat seedlings: By following the time course changes of NO synthase , superoxide synthase and ABA accumulation under dehydration stress, we found that ABA accumulation was preceeded by the changes of NOS and superoxide synthase. ABA accumulation induced by dehydtrion stress and osmotic stress can be blocked by NO scanvegers and NOS inhibitors, while only dehydration stress-induced ABA accumulation can be blocked by ROS scanvegers. Exogenous applied NO or ROS induced ABA accumulation in root tips of wheat seedlings, and synergistic effects were found between NO and NO. The in planta expereiments also proved that ROS and NO are involved in water stress-induced ABA accumulation.Ⅱ.

证据主要来自以离体根尖为材料的实验：(1)通过检测干旱胁迫下小麦根尖NOS活性、O〓合成酶活性和ABA积累的时间变化进程，发现ABA积累滞后于ROS和NO的变化；(2)抑制剂实验表明，NO清除剂和NOS抑制剂可以抑制自然干旱胁迫及渗透胁迫诱导的小麦根尖ABA积累，ROS清除剂抑制自然干旱胁迫诱导的ABA积累而不抑制渗透胁迫诱导的小麦根尖ABA积累；(3)在非胁迫条件下施加外源的ROS或NO可以诱导小麦根尖积累ABA，ROS和NO之间具有协同作用。

The tested parameters included: the effect of preculture duration for explants, the type of microcarriers, density of microcarrier particles used for DNA preparation, the effects of osmotic treatments, and plasmids with various constructions. Parameters of biolistic device including the flight distance of microcarriers (6 and 9 cm) and macrocarriers (4, 8, and 12 mm) were investigated.

评估之因子包括：培植体预培养天数、微载体种类及用量、高渗透压处理及转殖质体对转殖之影响；基因鎗测试之条件有：微载体至射击目標之飞行距离(6、9 cm)，大载片至挡片之距离（4、8及12 mm）。

The results showed that 7-day-precultured embryogenic calli had the best responses for bombardment among 2-7 day' preculture duration. Enhanced transformation efficiency was found in the explants treated with high osmotic medium 4h prior to till 24 h after bombardment. Particles of gold and tungsten were both found suitable for rice transformation and there was no adverse effect when tungsten particles were reduced to 1/3 standard amount for DNA precipitation on transient GUS gene expression. However, it was found that gold particle had higher GUS expression at 120 h post-bombardment. A preliminary microprojectile transformation system with an average of 15-20 blue spots/explant GUS expression was routinely obtained for 'Tainung 67' by using the particle gun with 1,100 psi rupture disk, 6 or 9 cm microcarrier flight distance and 4 mm of macrocarrier flight distance setting.

初步结果显示，以预培养2~7日之胚性癒合组织逐日测试转殖率，以预培养7日之培植体表现最佳；培植体於转殖前4小时至转殖后24小时以高渗透压培养基处理，有助於转殖效率之提高；比较金、钨粒子对转殖率在转殖后48h並无不同，但转殖后120 h取样，则金粒子组有较高之蓝点数；钨粒子用量可减少至1/3標准用量对转殖率並无影响；利用基因鎗在使用1， 100 psi裂碟片、大载片至挡片之距离为4 mm、微载髁至射击目標之飞行距离6或9 cm之设定，GUS基因表现之平均蓝点数均可达15~20个／培植体。

By using an empirical potential of free energy on dsDNA which was obtained experimentally by Strey, a relation between total energy of chip and some factors, such as nanogeometric, physical. chemical characteristics of DNA, geometric dimension, macroscopical mechanical properties of chip, etc was formulated under the consideration of mechanical energy of microcantilever beam, electrostatic energy, configuration entropy, and osmotic energy of gene-layer.

首先，在考虑微悬臂梁机械能和基因层静电能、构型熵、渗透能的情况下，借助Strey通过实验得到的双链DNA自由能的经验势，建立了DNA纳观几何、物理、化学特征以及芯片几何尺寸、宏观力学性能等因素与基因芯片总能量之间的关系。
