OBJECTIVES/HYPOTHESIS Scaffold-free cartilage has been used to engineer biocompatible and mechanically stable neotracheas in vivo. The purpose of this animal study was to determine if neotracheal constructs, implanted paratracheally, could successfully be used for segmental tracheal reconstruction. STUDY DESIGN Animal study. METHODS Culture-expanded auricular rabbit chondrocytes were used t...

Quantification of the permeability of connective tissue linings isolated from implanted capsules was achieved by two types of experiments. The objective of the first type was to determine the restriction offered by the lining to diffusion of 'I-labeled human serum albumin. The restricted diffusion coefficient of albumin with respect to the connective tissue lining the luminal capsule surface (i...

background and aim: steroid-resistant nephrotic syndrome (srns) accounts for 10%-20% of all cases of idiopathic nephrotic syndrome. these patients are at risk of developing end-stage renal disease. the aim of this study was to determine the demographic characteristics, renal biopsy findings, response to immunosuppressive treatment, and prognosis in pediatric patients with srns.materials and met...

The extracellular lining of the pulmonary peripheral airways is of vital importance to the lung. In this report, some aspects of the pulmonary extracellular lining and the epithelial cells believed to be responsible for its formation and secretion have been briefly reviewed. The influence of a number of toxic agents on the extracellular lining either directly or via those cells involved in its ...

The cytotoxicity of nine soft and hard lining materials (Mollosil Plus, Ufi Gel SC, Visco-gel, Molloplast-B, GC Tissue Conditioner, Vertex Rapid Simplified, GC Reline Hard, Vertex Self-Curing, Ufi Gel hard C) was evaluated using human gingival fibroblasts (HGFs). Twelve disk samples per lining material were prepared and incubated for 24, 48, 72, and 96 h. Cytotoxicity of each lining material's ...

Quantification of the permeability of connective tissue linings isolated from implanted capsules was achieved by two types of experiments. The objective of the first type was to determine the restriction offered by the lining to diffusion of 125I-labeled human serum albumin. The restricted diffusion coefficient of albumin with respect to the connective tissue lining the luminal capsule surface ...

The present study investigated the effect of using PRAAT as a free computer software package for the scientific analysis of speech in phonetics on pre-intermediate Iranian English as foreign language (EFL) learners’ supra segmental features (i.e., intonation and stress). The design of the study was a Quasi-experimental research design with a pre and post-test. In doing so...

The antigenic phenotype of human synovial lining cells in normal and hyperplastic synovium intima was determined with a panel of monoclonal antibodies directed against a large number of well defined myeloid (macrophage/granulocyte associated) antigens. Synovial lining cells express numerous macrophage associated antigens, including CD11b (CR3), CD13, CD14, CD16 (FcRIII), CD18, CD32 (FcRII), CD4...

background: primary focal segmental glomerulosclerosis (fsgs) is defined by the presence of proteinuria, often in nephrotic range and pathologically by segmental scars (ss). the aim of this study is to identify the possible predictors of complete remission or progression to chronic kidney disease in iranian adults with primary focal segmental glomerulosclerosis. methods: in this historical coho...
