BACKGROUND In the fine needle aspiration cytology (FNAC) for tumors of the breast, evaluation is frequently difficult because of the thick-layered cell clusters and blood inclusion. Such problems may be resolved by the returned cell block method, but its use has not spread worldwide. Here, we examined the application of the returned cell block method to cases involving difficulty in the evaluat...

BACKGROUND Vitreoretinal lymphoma (VRL) is a life- and sight-threatening disorder. The aim of this study was to analyze the usefulness of the cell block method for diagnosis of VRL. METHODS Sixteen eyes in 12 patients with VRL, and 4 eyes in 4 patients with idiopathic uveitis presenting with vitreous opacity were enrolled in this study. Both undiluted vitreous and diluted fluids were isolated...

Antibacterial activity without cell cytotoxicity is conferred to common plastic materials by dispersion of amphiphilic cationic methacrylate-based block copolymers (0.5–2 wt%), while maintaining the mechanical properties materials.

OBJECTIVE Ultrasound-guided fine-needle aspiration (US-FNA) biopsy has proven to be an accurate and efficient tool in thyroid nodule evaluation. We evaluated whether cell block adds to the diagnostic accuracy of US-FNA. SUBJECTS AND METHODS Three hundred twenty-eight consecutive patients underwent US-FNA, cytology and cell block evaluation. Six slides were prepared for each patient and staine...

Of 39 monoclonal antibodies that bind the cell surface of aggregating Dictyostelium discoideum, 4 block 76-98% of cell-cell adhesion measured in an in vitro assay. The active antibodies all bind in the range of 10(6) antigenic sites/cell surface and react with more than one material on nitrocellulose blots prepared after polyacrylamide gel electrophoresis of whole aggregating cells in sodium do...

purpose: to evaluate the results of one 60-degree block conjunctival limbal autograft (clau) surgery in patients with unilateral total limbal stem cell deficiency (lscd). methods: five eyes of 5 patients were included. all patients had a history of chronic total unilateral lscd due to a chemical injury. two patients underwent one 60-degree block clau with amniotic membrane transplantation, two ...
