انگور شاهانی vitis vinifera l.(shahani grape) به خانواده vitaceae تعلق دارد. این میوه به دلیل داشتن ترکیبات فنولی در پیشگیری از بسیاری بیماری ها مثل انواع سرطان و عفونت ها مصرف می شود. این پژوهش با هدف بررسی ساختارهای تشریحی-تکوینی خواص ضد میکروبی، ضد جهشی و آنتی اکسیدانی گیاه انگور شاهانی انجام شد. در این تحقیق از روش های متداول سلول-بافت شناسی، تهیه برش های دستی، میکروتومی، رنگ آمیزی های لازم...
colorado potato beetle, leptinotarsa decemlineata is one of the major insect pests of potato. toxicity of spinosad, as a bio-rational insecticide, was investigated against various developmental stages of this pest. bioassays were conducted by using the eggs, neonates, first, second, third and fourth instar larvae and adults. the potato leaves were impregnated with different concentrations of sp...
Background Progress in medical science and success in increasing the survival rate of vulnerable infants have raised the issue of future development in these children. This study aimed to investigate the relationship between small for gestational age (SGA) status at birth and developmental delay in children aged 4 to 60 months. Materials and Methods This study was a correlation descriptive thro...
Populations of Arboridia kermanshah Dlabola is increasing in Isfahan vineyards. In this study, some morphological characteristics of the immature stages, over wintering sites, number of generations per year, and seasonal population fluctuations of this pest were studied in vineyards in Isfahan Province. Eggs showed apparently four distinct embryonic developmental stages. At 25.8 ±2˚C, developme...

To describe the morphological and histological changes during the annual reproductive cycle of the gonads of Cyprinion tenuiradius, a total of 341 specimens (102 female and 235 male specimens) were collected monthly from the Rudbal River (in the Qarah Aghaj sub-basin, the Persian Gulf basin), Firuzabad, Fars Province, southern Iran. The randomly sampling was adequate to collect males and female...
PURPOSE This study investigated the developmental stages of third molars in relation to chronological age and compared third molar development according to location and gender. MATERIALS AND METHODS A retrospective analysis of panoramic radiographs of 2490 patients aged between 6 and 24 years was conducted, and the developmental stages of the third molars were evaluated using the modified Dem...
We investigate a developmental tree-adjoining grammar guided genetic programming system (DTAG3P), in which genetic operator application rates are adapted during evolution. We previously showed developmental evaluation could promote structured solutions and improve performance in symbolic regression problems. However testing on parity problems revealed an unanticipated problem, that good buildin...
This case study of adaptation in Arabidopsis thaliana shows that natural selection on early life stages can be intense and can influence the evolution of subsequent traits. Two mechanisms contribute to this influence: pleiotropy across developmental stages and developmental niche construction. Examples are given of pleiotropy of environmentally cued development across life stages, and potential...
