Cocoa confers life span extension in Drosophila melanogaster.
Cocoa is thought to be an excellent source of antioxidants. Here, we investigated the effects of cocoa supplementation on Drosophila melanogaster life span under different oxidative stress conditions. Our results illustrate that a moderate supplementation of cocoa under normoxia increases the average life span, whereas, at higher concentrations, average life span is normal. Under hyperoxia or i...

Article history: Received on: 31/07/2015 Revised on: 11/08/2015 Accepted on: 20/08/2015 Available online: 24/08/2015 Free radicals and oxidative stress are recognized as important factors in the biology of aging as well as in many age-related diseases. Dietary antioxidant plays a potential role in the reduction of age-related diseases. Many medicinal plants are rich source of antioxidants and p...
متن کاملQuantitative trait loci affecting life span in replicated populations of Drosophila melanogaster. II. Response to selection.
Three selection experiments were used to identify chromosome regions that contain QTL affecting late-life and early-life fitness in Drosophila melanogaster. The selection experiments were initiated by crossing pairs of inbred lines that had been derived from outbred laboratory populations that had different mean life spans. QTL regions were located by association with microsatellite markers tha...

انتخاب نامساعد یکی از مشکلات اساسی در صنعت بیمه است. که ابتدا در سال 1960، توسط روتشیلد واستیگلیتز مورد بحث ومطالعه قرار گرفت ازآن موقع تاکنون بسیاری از پژوهشگران مدل های مختلفی را برای تجزیه و تحلیل تقاضا برای صنعت بیمه عمر که تماما ناشی از عدم قطعیت در این صنعت میباشد انجام داده اند .وهدف از آن پیدا کردن شرایطی است که تحت آن شرایط انتخاب یا کنار گذاشتن یک بیمه گزار به نفع و یا زیان شرکت بیمه ...
15 صفحه اولQuantitative trait loci for life span in Drosophila melanogaster: interactions with genetic background and larval density.
The genetic architecture of variation in adult life span was examined for a population of recombinant inbred lines, each of which had been crossed to both inbred parental strains from which the lines were derived, after emergence from both high and low larval density. QTL affecting life span were mapped within each sex and larval density treatment by linkage to highly polymorphic roo-transposab...
