11-P002 Left–right asymmetry of ascidian larvae is determined by rotation of the whole embryos within the vitelline membrane
Specification of the mammalian left–right (L–R) axis is controlled by fluid flows in the embryonic node, a ciliated pit like structure located at the distal tip of the mouse embryo. Nodal cilia rotate so as to cause a leftward fluid flow-this has been experimentally demonstrated to control embryonic sidedness. How the embryo interprets this flow remains the subject of debate. The two cilia hypo...

control of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولNeurula rotation determines left-right asymmetry in ascidian tadpole larvae.
Tadpole larvae of the ascidian Halocynthia roretzi show morphological left-right asymmetry. The tail invariably bends towards the left side within the vitelline membrane. The structure of the larval brain is remarkably asymmetric. nodal, a conserved gene that shows left-sided expression, is also expressed on the left side in H. roretzi but in the epidermis unlike in vertebrates. We show that no...
