Targeted ablation of ^-crystal I in-synthesizing cells produces lens-deficient eyes in transgenic mice
Genetic ablation techniques were used to study the role of the lens in mammalian eye development. Ablation was accomplished by microinjecting murine eggs with chimeric DNA constructs in which the aA-crystallin gene regulatory sequence (—366 to +46) was fused to the highly cvtotoxic diphtheria toxin gene coding sequence. For genetic ablation to be successful the promoter regulating expression sh...

متن کاملTemperature Tunability of Dielectric/ Liquid Crystal / Dielectric Photonic Crystal Structures
Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect ofte...
متن کاملEvolving eyes.
Despite the incredible diversity among extant eyes, laws of physics constrain how light can be collected resulting in only eight known optical systems in animal eyes. Surprisingly, all animal eyes share a common molecular strategy using opsin for catching photons, but there are a diverse collection of mechanisms with proteins unrelated to each other used to focus light for vision. However, opsi...
متن کاملEyes East
Last November I visited Japan for the first time and was lucky enough to visit individual labs at four different universities. As I talked with my hosts and their students I was struck by the differences between the scientific cultures of Japan and the United States. At its best, American science is all about the triumph of excellence in the land of opportunity, with 27-year-old assistant profe...
