半衰期

This method could increase molecular weight of the medicamentous protein and decrease the immunogenicity of the heterogenesis protein, thereby it could diminish glomerular filtration rate and clearance rate in vivo.

该方法增大了蛋白药物的分子量，降低了异源蛋白的免疫原性，从而可以减少肾小球滤过率和体内清除率，有效提高IL-2在体内的半衰期，具有非常广阔的生产以及临床应用前景。

Function, and so on, hirudin has been fused with some other functional proteins in recent years.

From the half life of the hydantoin racemization, could be seen increase the temperature and pH are both good for the racemization, but if the pH value is too high the alkaline hydrolysis will happen and make some loss.

由海因消旋的半衰期可看出提高温度和pH对海因的消旋均有利，但pH过高的情况下海因则会发生碱解反应从而造成损失。

Through a lot of tests,we brought forward a flood water quality control method,analysed the changes of flood well hygroscope ability caused by the changes of water quality control,Predicted flood well's harmful radii and the half life of hygroscope ability changes.

通过大量的试验研究提出了注水水质调控方法，通过以采油二厂七中东八道湾组油藏为主，分析了水质控制指标的变化带来的注水井吸水能力的变化，预测了注水井的伤害半径以及吸水能力变化的半衰期。

Amiodarone seems to have a similar effect as lidocaine on the hyperalgesia seen in the rat model of neuropathic pain.

考虑到其在人体的半衰期很长，胺碘酮有望长时间缓解神经性疼痛。

The maximum absorption peak was at long wavelength (＞650nm), extinction coefficient achieves 10〓 degree, which was one degree higher than HpD. The study has revealed that CPD photosensitizer appeared blue movement under the relevant body environment. The spectra parameters provided basis for selecting light source of PDT. Measurement system which measured singlet oxygen and its quantum yields within the infare range had been set up and the quantum yields of singlet oxygen for CPD were reported: the quantum yields of singlet oxygen for CPD〓 was the highest (φ=0.83) while he quantum yields of singlet oxygen for CPD〓 was the lowest (φ=0.83). Photobleaching's half life time was studied.

给出了此类光敏剂的光谱指认和光谱参数：其吸收光谱峰值位于长波红光区(＞650nm)，摩尔消光系数达10〓LmoL〓cm〓量级，比血卟啉衍生物高出一个数量级；研究揭示了此类光敏剂在近似体内环境下光吸收的蓝移现象，为光动力治疗光源的选择提供了依据；建立了在近红外光谱区中测定敏化单态氧的光谱和量子产率测量系统，报导了该类光敏剂敏化单态氧的量子产率，其中CPD〓的单态氧量子产率最高(φ＝0.83)，CPD〓的单态氧量子产率最低(φ＝0.51)；测定了二氢卟吩类光敏剂的光漂白半衰期。

Mcl-1 is a labile Bcl-2 family member that plays an apical role in many cell survival and death programs.
