CA II and AQP5 expression levels were determined by immunofluorescence and immunoblotting, while CA activity and Na, K-ATPase activity by a colorimetric assay. Anhidrotic mice treated by topiramate did not differ from controls in average secretory coil diameter, CA II expression, CA activity and Na, K-ATPase activity.

应用免疫荧光和western blot技术发现：小鼠在托吡酯处理后泌汗减少，碳酸酐酶同功酶II型(carbonic anhydraseII，CAII)蛋白表达未出现显著变化，但汗腺组织胞膜的水通道蛋白-5(aquaporin-5，AQP5)表达量下调。

As reported by some researchers, most of them enters the ER and is esterified by an ER enzyme ACAT2,then incorporated with apo B48 to produce de novo chylomicron which goes into the lymph and then to the circulation.

据文献报道，进入肠细胞的胆固醇能在酰基辅酶A：胆固醇酰基转移酶2(Acyl-Coenzyme A Cholesterol Acyltransferase，ACAT2)的作用下形成胆固醇酯，并与apoB48组装形成乳糜微粒，经淋巴进入血液。

Diglyceride is one kind of new and promising chemical product. In this paper, the preparation of DG in different conditions were studied.

本论文主要对双甘酯的酶促甘油醇解、水解以及超声波外力场辅助酶促水解制备进行了研究。

Using Novozym 435 as catalyst, transesterification of ethyl ferulate with triolein to form ferulyl oleins in solvent-free medium was investigated.

以Novozym435脂肪酶为催化剂，以阿魏酸乙酯和三油酸甘油酷为底物，合成阿魏酸双油酸甘油酯。

It was discovered that trimalonic acid C60、fullerol、dimalonic[60]fullerene hydrolysate、tetraethyl methano[60]fullerenediphosphonate、methano[60]fullerenediphosphonic acid and dimalonic acid C60 exhibited different inhibitory effects on Taq DNA polymerase.

实验发现，6种富勒烯衍生物三丙二酸富勒烯、富勒醇、富勒烯丙二酸水解物、亚甲基富勒烯二膦酸四乙酯、亚甲基富勒烯二膦酸四乙酯的完全水解物和二丙二酸富勒烯对Taq DNA聚合酶存在不同程度的抑制作用。

These triglyceride-enriched but cholesterol-depleted HDL particles are more prone to be catabolized by hepatic lipase which hydrolyzes phospholipids and triglycerides and reduces the size and density of HDL particles.

这些富含甘油三酯，但缺乏胆固醇的HDL 颗粒更易被肝脂酶分解，使磷脂和甘油三酯水解，HDL颗粒变小且密度降低。

Objective The effects of two pyrethroids,permethrin and deltamethrin,on metabolizing enzymes in rat brain and liver were investigated.

目的 实验研究溴氰菊酯和氯菊酯对大鼠脑组织及肝脏某些生物转化酶的影响。

Native tapioca starch granules were not treated with any alkaline and consequently there was no starch swelling Moreover, Huangllll reported that in preparing CLTS with low DC, except the formation of cross linking tarch molecules with POC13 there were also some esterification between starch molecule and POC13 due to a small amount of POC13 added The introduction of hydrophilic ester bond during the cross linking reaction could induce hydration of starch chains, resulting in easy absorption of enzyme onto starch granule

乡土木薯淀粉颗粒不处理与任何碱性因此没淀粉膨胀此外， huangllll报备clts低直流，除形成交叉连接tarch分子poc13还有一些酯化淀粉分子和poc13 由于少量poc13续引进亲水酯键的交联反应诱使水化的淀粉链，造成容易吸收的酶转入淀粉颗粒

The enzyme tannase, which is used in the present invention, is known to hydrolyse the galloyl ester linkages of polyphenolic substrates such as tannic acid, tea polyphenol gallates, and the like.

我们知道，这种在本发明中所使用的丹宁酶，可水解多酚酸类物质的棓酸酯键，如丹宁酸，茶叶的棓酸多酚酯及其类似物。

Then, the hapten LBc and LBs was conjugated to bovine serum albumin with CDI method to form immuno-antigen; the haptens LBc, LBs and LBy was conjugated to ovalbumin with mixed anhydride method to form the the coating antigens.The new zealand rabbits were immunized by conjugate of LBc-BSA and LBs-BSA, and titres of anti-bifenthrin serum (5.12×10~4, 3.2×10~5) were determined by non-competitive indirect enzyme-linked assay procedure.

通过碳二亚胺法将LBc和LBs交联于牛血清蛋白作为免疫抗原，通过活泼酯法将分别LBc、LBs和LBy交联于卵清蛋白作为包被抗原，LBc-BSA和LBs为免疫原制备了联苯菊酯的兔抗血清，非竞争间接酶联免疫吸附分析方法测得其效价达5.12×10~4和3.2×10~5。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
