Comparison of gonadal hormone levels in turkey embryos incubated in long-term shell-less culture and in ovo.
Changes in concentrations of 17beta-estradiol (E2) and androgenic hormones were measured in turkey embryos incubated in long-term, shell-less culture (ex ovo) and in ovo. Blood samples were obtained from both sets of embryos on Days 14, 16, 18, 20, and 22 and from embryos incubated in ovo on Days 24, 26, and 28. Ex ovo and in ovo embryos showed no differences in either hormone within sexes, wit...
متن کاملFinancing Long-term Care: The Role of Culture and Social Norms; Comment on “Financing Long-term Care: Lessons From Japan”
Based on the experiences of Japan and Germany, Ikegami argues that middle-income countries should introduce public long-term care insurance (LTCi) at an early stage, before benefits have expanded as a result of ad hoc policy decisions to win popular support. The experience of the Netherlands, however, shows that an early introduction of public LTCi may not prevent, but ...

از گذشته تا کنون، تحقیقات بسیاری صورت گرفته است که همگی به گونه ای بر مثمر ثمر بودن استفاده از استراتژی های یادگیری لغت در یک زبان بیگانه اذعان داشته اند. این تحقیق به بررسی تاثیر دو روش مختلف آموزش واژگان انگلیسی (کلیدی و بافتی) بر تلفظ و دانش لغوی فراگیران ایرانی زیر متوسط زبان انگلیسی و بر ماندگاری آن در حافظه می پردازد. به این منظور، تعداد شصت نفر از زبان آموزان ایرانی هشت تا چهارده ساله با...
15 صفحه اولUltrastructural observations on the chorionic epithelium, parathyroid glands and bones from chick embryos developed in shell-less culture.
Three-day-old chick embryos were cultured in Petri dishes until they reached developmental stages 37 or 39 (Hamburger & Hamilton, 1951). The electron microscopical study of the chorio-allantoic membranes showed that, even in the absence of the shell and the corresponding calcium supply, 'capillary-covering' and 'villus-cavity' cells differentiated well. The parathyroid glands from the cultured ...
متن کاملCulture of preimplantation embryos and its long-term effects on gene expression and phenotype.
A growing number of medical, scientific and biotechnological procedures rely on culture of mammalian preimplantation embryos. This review presents currently available data on aberrant offspring development that sometimes arises from commonly applied in-vitro procedures in humans, ruminant species and mice. Comparison between mammalian species reveals similarities in the phenotypic abnormalities...
