It is a matter of considerable clinical interest whether removal of the lens causes regression of pseudoexfoliation of the lens capsule. Before the paper by Dvorak-Theobald (I954), pseudoexfoliation of the lens capsule was often confused with true exfoliation, and it was suggested that lens extraction caused the condition to disappear (Irvine, I940; Gradle and Sugar, I947). After this paper app...
We present our work on information extraction from multiple, multi-lingual sources for the Multimedia Indexing and Searching Environment (MUMIS), a project aiming at developing technology to produce formal annotations about essential events in multimedia programme material. The novelty of our approach consists on the use of a merging or cross-document coreference algorithm that aims at combinin...
We describe the histopathological findings of an enucleation specimen from a clinically undiagnosed case of phacoanaphylaxis which occurred after extracapsular cataract extraction with intraocular lens implantation. Phacoanaphylaxis, a granulomatous inflammatory response to liberated lens protein, is potentially curable by prompt removal of residual lens material. This case emphasises that the ...
background: alveolar ridge preservation could be performed immediately following tooth extraction to limit dimensional changes of alveolar process due to bone resorption. the aim of this study was to compare the clinical and histologic outcomes of socket preservation using two different graft materials; deproteinized bovine bone mineral (dbbm) and demineralized freeze‑dried bone allograft (dfdb...
in this work, the template, monomer and cross-linker with the ratio of 1:8:40 were used to synthesize molecularly imprinted polymers (mips) for extraction of the bioactive chemical compounds from some traditional herbs as a sorbent material. quercetin, methacrylic acid (maa), trimethylolpropanetrimethacrylate (trim) and tetrahydrofuran (thf) were used as a template, functional monomer, cross-li...
Congenital amusia is a lifelong disorder of music processing that has been ascribed to impaired pitch perception and memory. The present study tested a large group of amusics (n=17) and provided evidence that their pitch deficit affects pitch processing in speech to a lesser extent: Fine-grained pitch discrimination was better in spoken syllables than in acoustically matched tones. Unlike amusi...
Abstract Background and objectives: Paraffin-embedded tissues and clinical samples are a valuable resource for molecular genetic studies, but the extraction of high-quality genomic DNA from this tissues is still a problematic issue. In the Present study, the efficiency of two DNA extraction protocols, a commercial kit and a traditional method based on heating and K Proteinase was compared. Mate...
INTRODUCTION The objective of this study was to compare three capsaicin extraction methods: Shoxlet, Ultrasound-assisted Extraction (UAE), and Shaker-assisted Extraction (SAE) from Habanero pepper, CNPH 15.192. MATERIALS AND METHODS The different parameters evaluated were alcohol degree, time extraction, and solid-solvent ratio using response surface methodology (RSM). RESULTS The three par...
The aim of this study was to evaluate the clinical relevance of autogenous fresh demineralized tooth (Auto-FDT) prepared at chairside immediately after extraction for socket preservation. Teeth were processed to graft materials in block, chip, or powder types immediately after extraction. Extraction sockets were filled with these materials and dental implants were installed immediately or after...
PCBs are persistent organic pollutants which, due to high environmental hazards, must be traced, determined, and decomposed to reduce their risks. . To detect this material in the soil, the method of extraction and appropriate measuring conditions should be investigated. Two soil samples with two kg weight were selected with two different soil textures and the solutions of soil were made with t...
