Multidrug resistance (MDR) is a primary hindrance to curative cancer chemotherapy. In this respect, lysosomes were suggested to play a role in intrinsic MDR by sequestering protonated hydrophobic weak base chemotherapeutics away from their intracellular target sites. Here we show that intrinsic resistance to sunitinib, a hydrophobic weak base tyrosine kinase inhibitor known to accumulate in lys...
در قسمت اول این تحقیق، کمپلکس [fe-schiff base] با روش اشباع سازی در نانوراکتورsba-15 تثبیت شده است. این نانو کاتالیزور به وسیله تکنیک هایxrd ،tem ، bet (جذب – واجذب نیتروژن(، ir، uv و tga شناسایی شده اند. الگوی xrd و تصویر tem مربوط به [fe-schiff base/sba-15] ساختار هگزاگونال منظم را در مزوحفره های سیلیکا نشان دادند. ایزوترم جذب – واجذب نیتروژن [fe-schiff base/sba-15] بر طبق دسته بندی آیوپاک بر...
If one has a multiclass classification problem and wants to boost a multiclass base classifier AdaBoost.M1 is a well known and widely applicated boosting algorithm. However AdaBoost.M1 does not work, if the base classifier is too weak. We show, that with a modification of only one line of AdaBoost.M1 one can make it usable for weak base classifiers, too. The resulting classifier AdaBoost.M1W is...
In this article, we analyzed the efficiency of food and beverage companies that were accepted in stock market, using a nonlinear model. This model eliminates the weak points of base Data Envelopment Models in high computing, lack of integration and too many numbers of zero weights. Taking into account that in this study we developed the base Data Envelopment Analysis model, the research method...
