Human albumin(HA)is a very important blood product which requires strict quality *** precipitation is a key step which has a great effect on the quality of final ***,a new method based on quality by design(QbD)was proposed to investigate thefeasibility of realizing online quality control with the help of near infrared spectroscopy(NIRS)and *** pH value is the critical process parameter(CPP)in acid precipitationprocess,which is used as the end-point *** batches,a total of 74 samples of acidprecipitation process,were simulated in our *** batches were selected randomly as cali-bration set and remaining two batches as validation ***,the analysis based on materialinformation and three dfferent variable selection methods,including interval partial least squaresregression(iPLS),competitive adaptive reweighted sampling(CARS)and correlation coeficient(CC)were compared for eliminating irrelevant variables,Fimally,iPLS was used for *** quantitative model was built up by partial least squares regression(PLSR).Thevalues of determination coeficients(R^(2)_(C) and R^(2)_(P)),root mean squares error of prediction(RMSEP),root mean squares error of calibration(RMSEC)and root mean squared error of crossvalidation(RMSECV)were 0.969,0.953,0.0496,0.0695 and 0.0826,*** paired t test and repeatability test showed that the model had good prediction ability and *** results indicated that PLSR model could give accurate measurement of the pH value.

With the continuous in-depth study of the interaction mechanism between viruses and hosts,the virus has become a promising tool in cancer *** fact,many oncolytic viruses with selectivity and effectiveness have been used in cancer *** enterovirus is one of the most convenient sources to generate oncolytic viruses,however,the high seroprevalence of some enteroviruses limits its application which urges to exploit more oncolytic enteroviruses.
