OBJECTIVE To report the outcome of mushroom keratoplasty for the treatment of full thickness corneal disease in pediatric patients with healthy endothelium. METHODS A retrospective analysis of pediatric patients who underwent mushroom keratoplasty. The medical records of pediatric patients suffering from full thickness corneal stromal disease with normal endothelium who underwent mushroom ker...

a r t i c l e i n f o Lamellae are thin, often discontinuous layers of clay-enriched material that are associated with iron oxides and may occur in Alfisols, Ultisols, Mollisols, Entisols, Inceptisols, or Spodosols. Our analysis of the SSURGO database revealed that there are 118 soil series with lamellae that represent six orders, 14 suborders, and 25 great groups, and 25 subgroups. In Soil Tax...

Abstract Directionally solidified B4C–NbB2-SiC ternary composites were prepared by a floating zone method based on crucible-free melting of compacted powders. The eutectic composition B4C–15NbB2–35SiC (mol.%) was characterized boron carbide matrix, directionally reinforced lamella-type NbB2 and SiC phases. inclusions about 1−2 μm in thickness uniformly dispersed B4C matrix B4C–NbB2–SiC composit...

In interference-reflection microscopy, used for investigating cell-substratum separation, it is commonly believed that cytoplasmic thickness can be ignored, provided a high illuminating numerical aperture (INA) is used. It is shown here that even when a maximal INA is used, cytoplasmic lamellae of I micrometer or less can be major determinants of the image. The leading lamella of spreading tiss...

Wild-type potato (Solanum tuberosum L.) plants and their transformants harboring agrobacterial rolB or rolC genes under control of the patatin class I promoter were cultured in vitro. These plants were used as a source of single-node stem cuttings. The structure of native starch in tubers formed on cuttings was determined using methods of X-ray scattering and differential scanning microcalorime...

Skin in the tadpole of anuran larvae prior to metamorphosis is composed of two layers of epidermal cells (Leeson and Threadgold, 1961; Chapman and Dawson, 1961; Edds and Sweeny, 1960, 1962), a laminated basement lamella, and a layer of dermal mesenchyme cells apposed to the underside of the basement lamella. An adepidermal space and membrane (Salpeter and Singer, 1959, 1960) separate epidermis ...

We describe a modified technique for loading donor corneal endothelial lamella onto a Busin glide(®) without causing wrinkles, as part of the procedure of Descemet-stripping automated endothelial keratoplasty. Briefly, after punching out a composite of the donor-endothelial lamella and a microkeratome-dissected cap, several drops of dispersive ophthalmic viscosurgical device are placed onto the...

PURPOSE To present a technique that creates a neofenestration in the dissecting lamella of chronic aortic dissections using standard or intravenous ultrasound (IVUS)-guided reentry devices. TECHNIQUE To create a neofenestration, a standard or IVUS-guided reentry device is deployed in either the true or false aortic lumen while a balloon is simultaneously inflated in the opposite lumen to stab...

BACKGROUND The transport of labeled G-actin from the mid-lamella region to the leading edge in a highly motile malignant rat fibroblast line has been studied using fluorescence localization after photobleaching or FLAP, and the transit times recorded in these experiments were so fast that simple diffusion was deemed an insufficient explanation (see Zicha et al., Science, v. 300, pp. 142-145 [1]...
