胸腺嘧啶

"Our study indicates that switching a thymidine analog to tenofovir represents a new treatment option for people with lipoatrophy which is as effective at allowing fat recovery as the established standard of switch to abacavir," Dr. Moyle said after the presentation."In addition, tenofovir had improved tolerability and leads to significantly better lipid outcomes than the switch to abacavir."

Moyle医师表示，根据本研究，从类胸腺嘧啶药物改为tenoforvir，这代表了一项新的治疗法，对於脂肪萎缩的患者，改用tenoforvir对於恢复脂肪的效果和改用abacavir是一样的；再则，Tenoforvir有著更好的耐受度，这使得其在脂肪的恢复上，效果比abacavir还要显著。

Their structures were identified by chemical and spectral analysis. RESULTS Five compounds were isolated and identified as stigmasterol 3-O-β-D-glucopyranoside, 20β-hydroxy-ecdysone,β-L-thymidine, pennogenin 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside and pennogenin 3-O-α-L-rhamnopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→4)-[α-L-rhamnopyranosyl-(1→2)-]-β-D-glucopyranoiside.

结果 分离并鉴定了5个化合物，分别是Δ5，22-豆甾醇3-O-β-D-葡萄吡喃糖苷，20β-羟基蜕皮激素，β-L-脱氧胸腺嘧啶苷，偏诺皂苷元3-O-α-L-鼠李吡喃糖基－(1→2)-β-D-葡萄吡喃糖苷和偏诺皂苷元3-O-α-L-鼠李吡喃糖基－(1→4)-α-L-鼠李吡喃糖基－(1→4)-［α-L-鼠李吡喃糖基－(1→2)-］-β-D-葡萄吡喃糖苷。

Three thymine radicals were observed in our experiment.

实验观察到三种胸腺嘧啶自由基。

Either two thymine bases are lined up in just the right way to bond when the UV hits, or they're not.

当受到紫外线伤害的时候，胸腺嘧啶或者线性排列以正确的方式形成键或者不产生键。

The free radicals formed from gamma-irradiated aqueous solutions of thymine have been investigated by the spin-trapping method.

本文用自旋陷阱法研究了γ射线照射胸腺嘧啶水溶液生成的自由基。

The important damage type of DNA in cell, the thymine photodimerization, was studied.

本论文中我们欲探讨生物细胞中重要遗传信息携带分子- DNA -受紫外线照射时导致之常见损坏结构-胸腺嘧啶二聚体-的可能形成过程。

Progesterone increased the formation of the CDK2-p21 and CDK2-p27 complexes, but not the CDK4-p21 and CDK4-p27 complexes. Moreover, the assayable CDK2, but not CDK4, activity was concentration-dependently decreased by progesterone treatment.

藉由同时给予p21与p27反义寡核苷酸造成p21与p27的表现被抑制，会回复助孕酮所产生之胸腺嘧啶核甘标记嵌合([3H]thymidine incorporation)的抑制。

In the dehydrogenating process,the anionic A-T fragmentgradually changes its electronic configuration fromπ~* toσ~* state,like the singlebases adenine and thymine.

在脱氢过程中，阴离子A-T的碎片会逐渐改变它的低能电子组态，从π~*态转变到σ~*态，这种变化跟在单个碱基腺嘌呤和胸腺嘧啶的情况相似。

In one model, the DNA cooperatively unwinds, while base pairing remains intact.

这组科学家指出，拉伸最初可能始于腺嘌呤和胸腺嘧啶丰富的区域，而且双链DNA需要一个最低程度的力量才能开始分解。

With the silver colloid, the bands at 732, 960 and 1333 cm-1 for adenine, 1466 cm-1 for deoxyribose, and 1652 cm-1 for the C=O group of thymine are observably enhanced.

实验结果表明，在银胶作为基底的SERS光谱中，归属于腺嘌呤组分的732cm-1、960cm-1、1333cm-1以及归属于胸腺嘧啶C=O基团的1652cm-1的拉曼信号得到明显的增强。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
