We present a seventy-three year-old female diagnosed with lens coloboma when she was going to be operated on for cataracts.The incidence of congenital coloboma of the eye is estimated to be 0.5 per 10000 newborns in Spain, 1.4 in France, 2.6 in United States, and 7.5 in China. The diagnosis is clinical by observing the defect.

Despite more than a century of organolead chemistry, all isolable organolead compounds have thus far been confined to Pb-C single bonds. Here we disclose the synthesis, structural authentication, and reactivity of room-temperature-stable plumbynes ([(CH2)(NDipp)]2PCPbAr; Ar = C6H3-2,6-Mes2 or C6H3-2,6-Trip2; Mes = mesityl; Trip = C6H2-2,4,6-iPr3)─the ...

Advanced Drug Delivery Reviews, 2001
Many drugs exist in the crystalline solid state due to reasons of stability and ease of handling during the various stages of drug development. Crystalline solids can exist in the form of polymorphs, solvates or hydrates. Phase transitions such as polymorph interconversion, desolvation of solvate, formation of hydrate and conversion of crystalline to ...

Crystallins and Their Complexes
2019The crystallins (α, β and γ), major constituent proteins of eye lens fiber cells play their critical role in maintaining the transparency and refractive index of the lens. Under different stress factors and with aging, β- and γ-crystallins start to unfold partially leading to their aggregation.

A 34-year-old woman had crystalline dystrophy of the retina associated with atrophy of the choriocapillaris and pigment epithelium, and pigment clumping in the fundus periphery. Consanguinity of her parents suggested an autosomal recessive inheritance pattern for this type of crystalline retinal dystrophy. The patient did not have corneal crystals. Her

Alpha A and alpha B-crystallins are a major protein component of the mammalian eye lens. Being a member of the small heat-shock protein family they possess chaperone-like function. The alpha-crystallins and especially alpha B is also found outside the lens having an extensive tissue distribution. Alpha B-crystallin is found to be over-expressed in many

Matter interacting classically with gravity in 3+1 dimensions usually gives rise to a continuum of degrees of freedom, so that, in any attempt to quantize the theory, ultraviolet divergences are nearly inevitable. Here, we investigate a theory that only displays a finite number of degrees of freedom in compact sections of space-time. In finite domains,
