Chromobodies are intracellular nanoprobes that combine the specificity of antibodies with the convenience of live fluorescence imaging in a flexible, DNA-encoded reagent. Here, we present the first application of this technique to an intact living vertebrate organism. We generated zebrafish lines expressing chromobodies that trace the major cytoskeletal component actin and the cell cycle marker...

During morphogenesis, organs grow to stereotyped sizes, but growth control mechanisms are poorly understood. Here, we measured the signaling dynamics of the morphogen Dpp, one of several Drosophila factors controlling morphogenetic growth, in the developing eye. In this tissue, the Dpp expression domain advances from the posterior to the anterior tissue edge. In front of this moving morphogen s...

از سده نوزدهم به بعد کشور عمان به دلیل موقعیت ژئواستراتژیک همواره در سیاستهای منطقهای به ویژه برای بریتانیا مهم و با اهمیت بوده است. در دهه شصت میلادی جنبش در منطقه ظفار شکل گرفت که برای ثبات منطقه خطرناک میشد در فضای جنگ سرد این مساله اهمیت پیدا کرد و رفته رفته به موضوع رقابت قدرتهای بزرگ تبدیل شد. در منطقه ایران و عربستان در آن وارد شدند و در سالهای 75 – 1972 م ایران در این زمینه مداخله نظامی...

And this is particularly apparent in regard to the paper of Hartley Rogers [1967a] based on his talk to the 1965 Tenth Logic Colloquium in Leicester, England. As Rogers states in his introduction to the paper “I shall be more concerned with presenting certain open prob...
