In order to develop efficient lures for soybean pod borer Leguminivora glycinivorella (Matsumura) in China, (E,E)-8,10-dodecadienyl acetate (EE-8,10-12:Ac), the main component of the pheromone of L. glycinivorella, and 12 structurally-related compounds were synthesised in good overall yields, regiospecificities, and stereo-selectivities via coupling reactions catalysed by Li₂CuCl₄. The effect o...

هدف از پژوهش حاضر، سنتز، ترکیب متوکسی آمیدو زانتات MAX و نشان‌دارسازی آن با رادیونوکلیید mTc99 به عنوان یک عامل تشخیصی نوین جهت تصویربرداری توموگرافی رایانه‌ای تک فوتونی (SPECT) می­‌باشد. لیگاند فوق واکنش بین دو ماده‌ی کلرواستامید (Chloroacetamide) مشتقات (Xanthate) نسبت‌های مولی معین سنتز شد. سپس فرایند طریق دوشیدن ژنراتور (mTc99Mo/99) روش مستقیم انجام گرفت. این ترتیب که قلع کلرید کاهنده مورد ...

Suppressor of zeste 12, a Polycomb group gene in Drosophila melanogaster; one piece in the epigenetic puzzle Anna Birve, Department of Molecular Biology, Umeå University, Sweden In multicellular organisms all cells in one individual have an identical genotype, and yet their bodies consist of many and very different tissues and thus many different cell types. Somehow there must be a difference i...

While many Plusiinae species commonly secrete (Z)-7-dodecenyl acetate (Z7-12:OAc) as a key pheromone component, female moths of the rice looper (Plusia festucae) exceptionally utilize (Z)-5-dodecenyl acetate (Z5-12:OAc) to communicate with their partners. GC-MS analysis of methyl esters derived from fatty acids included in the pheromone gland of P. festucae showed a series of esters monounsatur...
