Taxol® (generic name – Paclitaxel), the most promising chemotherapeuticagent was isolated from bark of different Taxus sp. As species arethreatened with extinction (endangered in Himalaya), thus it is imperativeto develop alternate and sustainable method for commercialization scaleup production paclitaxel. In this respect, physical chemical parametersare effective important key points active co...

A simple, quick and efficient method for isolating total RNA from heavy browning cells was developed by adding polyvinylpyrrolidone, mercaptoethanol and 3 M NaAc during the process of the Trizol (a kind of a widely used RNA extraction buffer) method. High-quality total RNA was isolated and synthesized to cDNA. Transcript levels of four paclitaxel biosynthetic pathway genes: dxr, hmgr, ggpps and...

High-cycle fatigue (HCF) behaviors of medium-carbon bainitic steels with various inclusion sizes and microstructural features were studied using the rotating–bending test. Here, different melting processes treated by three heat treatment routes incorporating bainite formation, namely bainite-based quenching plus partitioning (BQ&P), austempering (BAT) “disturbed austempering, DBAT”. The int...

وراثت مقاومت سفیدبالک گلخانه، Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae)، به دو ترکیب ایمیداکلوپرید و کلرپایریفوس مورد مطالعه قرار گرفت. در این پژوهش، از جمعیت فیلستان ورامین (FL) عنوان والد مقاوم فردیس کرج (FR) حساس استفاده شد. مقدار ترتیب حدودا 62/13 91/14 برابر بود. عدم وجود اختلاف معنی‌دار LC50 روی تلاقی‌های F1 (R♂×S♀) Fʹ1 (R♀×S♂) نشان داد که T. نوع اتوزومی (غیرجنسی) است. ه...
