زمینه و هدف: از آنجا که رابطه علت و معلولی آشکاری بین مصرف سیگار و ایجاد سرطان دهان وجود دارد؛ اخیرا سیتولوژی دهانی به عنوان روشی در غربالگری افراد high risk برای تشخیص زودرس تغییرات سلولی در مخاط دهان مطرح شده است و رنگ آمیزی نقره (تکنیک agnor) می تواند به عنوان روشی ارزشمند جهت کشف تغییرات اولیه سلولی محسوب گردد. مطالعه حاضر با هدف ارزیابی و مقایسه میانگین شمارش agnors در سلول های اسمیرهای ته...

This talk is focused on such systems in overload. We look at a single queue and consider the scenario where customers leave impatient as their waiting time grows too large. We propose a fluid (functional LLN) approximation of this system and investigate the fixed point of this approximation. This leads to several qualitative insights into the dynamics of PS models with impatience. We show that ...

Conrad Hal Waddington?s ?Experiments on Embryonic Induction III,? published in 1934 in the Journal of Experimental Biology, describes the discovery that the primitive streak [7] induces the mammalian embryo. Waddington?s hypothesis was that a transplanted primitive streak [7] could induce neural tissue in the ectoderm [8] of the rabbit [9] embryo. The primitive streak [7] defines the axis of an...

We describe the cloning, expression pattern and functional overexpression analysis of Xotx5b, a new member of the Otx gene family in Xenopus laevis. Early expression of Xotx5b resembles that of Xotx2, being detected in the organizer region at early gastrula stage, and, shortly after, also in anterior neuroectoderm. During neurula stages Xotx5b exhibits a changing and dynamic pattern of expressi...
