Malaria is a parasitic disease with limited chemotherapy options. Chemotherapy options are limited; moreover, drug resistant frequently occurs. The speed of drug development should be faster to overcome the emerging drug resistance. In the current study, a series of quinolone derivatives were subjected to quantitative structure activity relationship to identify the ideal physicochemical charact...

خوردگی فولاد یک مشکل بزرگ اقتصادی است بنابراین استفاده از بازدارنده ها یکی از عملی ترین روش ها برای محافظت از خوردگی فلزات به خصوص در محیط های خورنده و مهاجم است. بیشتر این بازدارنده ها ترکیبات آلی دارای اتمهای نیتروژن، اکسیژن و سولفور هستند. در این کار پژوهشی اثر بازدارندگی 8 نمونه از شیف-بازهای هیدرازونی بر روی خوردگی فولاد نرم بررسی شده است. یکی از مزایای این شیف بازها، تهیه ی راحت این ترکیب...

Objective(s): The structure- activity relationship of a series of 36 molecules, showing L-type calcium channel blocking was studied using a QSAR (quantitative structure–activity relationship) method. Materials and Methods: Structures were optimized by the semi-empirical AM1 quantum-chemical method which was also used to find structure-calcium channel blocking activity trends. Several types of ...

Quantitative genetics (QG) analyses variation in traits of humans, other animals, or plants in ways that take account of the genealogical relatedness of the individuals whose traits are observed. This article focuses on "classical" QG where the analysis of variation does not involve data on measurable genetic or environmental entities or factors. Classical QG analysis employs models of genes wi...
