Retinal transplantation aims to prevent blindness and to restore eyesight, i.e., to rescue photoreceptors or to replace damaged photoreceptors with the hope of reestablishing neural circuitry. Retinal donor tissue has been transplanted as dissociated cells or intact sheets. A promising experimental paradigm is the subretinal transplantation of sheets of fetal retina with or without its attached...

We examined the modulation of intrinsic (i.e., spontaneous) detrusor contractions by the urothelium and the lamina propria through optical mapping approaches. Normal adult and spinal cord-transected (SCT) rat bladders were stained with Ca2+- and voltage-sensitive dyes, and optical activity generated from intrinsic contractions was mapped from the mucosal surface of whole bladder sheets. Both no...

in this work, laser bending of perforated sheets has been investigated numerically. laser bending of perforated sheets is more complicated than non-perforated sheets due to their complex geometries. in this paper, laser bending of perforated sheets is studied numerically in the form of thermo-mechanical analysis with abaqus/implicit code. for this purpose, the effects of process and sheet param...

Footpad dermatitis (FPD) is a type of skin inflammation that causes necrotic lesions on the plantar surface of the footpads in commercial poultry, with significant animal welfare, and economic implications. To identify biomarkers for FPD development and wound healing, a battery cage trial was conducted in which a paper sheet was put on the bottom of cages to hold feces to induce FPD of broilers...

A detailed questionnaire with instructions and examples was mailed to the presidents or designated delegates of the national societies of cardiology represented in the European Society of Cardiology. They distributed a copy of the questionnaire to all institutions performing diagnostic or interventional cardiac catheterizations in their respective countries. Upon completion the questionnaires w...

the outstanding feature of the life of mesozoic time is the rise to dominance of the reptiles and their radiation into almost all modes of existence on the lands, in the waters, and in the air . chief place among the invertebrates is occupied by the cephalopods which reached at this time the culmination of their career. this is indicated by their extraordinary specialization along many lines, m...

a modified electrode was prepared by modification of the carbon paste electrode (cpe) with graphene nano-sheets. the fabricated modified electrode exhibited an electrocatalytic activity toward gallic acid (ga) oxidation because of good conductivity, low electron transfer resistance and catalytic effect. the graphene modified cpe had a lower overvoltage and enhanced electrical current respect to...

* Institut national d’études démographiques (1) Each year, this independent organization provides summary data sheets using figures issued by different sources – mainly the United Nations Population Division [2], the United States Census Bureau, the Council of Europe and INED [3] – based on all demographic data published by national statistics agencies and international organizations. Every oth...

BACKGROUND Representations of chemical datasets in spreadsheet format are important for ready data assimilation and manipulation. In addition to the normal spreadsheet facilities, chemical spreadsheets need to have visualisable chemical structures and data searchable by chemical as well as textual queries. Many such chemical spreadsheet tools are available, some operating in the familiar Micros...
