BACKGROUND An increase in surface roughness of ceramics may decrease strength and affect the clinical success of ceramic restorations. However, little is known about the effect of acidic agents on ceramic restorations. The aim of this study was to evaluate the surface roughness of dental ceramics after being immersed in acidic agents. METHODS Eighty-three ceramic disk specimens (12.0 mm in di...

BACKGROUND Significant portion of alphaA-crystallin in human lenses exists as C-terminal residues cleaved at residues 172, 168, and 162. Chaperone activity, determined with alcohol dehydrogenase (ADH) and betaL-crystallin as target proteins, was increased in alphaA(1-172) and decreased in alphaA(1-168) and alphaA(1-162). The purpose of this study was to show whether the absence of the C-termina...

Secretion of xylanase activities by Bacillus subtilis 168 supports the development of this well-defined genetic system for conversion of methylglucuronoxylan (MeGAXn [where n represents the number of xylose residues]) in the hemicellulose component of lignocellulosics to biobased products. In addition to the characterized glycosyl hydrolase family 11 (GH 11) endoxylanase designated XynA, B. sub...

The ubiquitous polyamines fulfil a variety of functions in all three kingdoms of life. However, little is known about the biosynthesis of these compounds in Gram-positive bacteria. We show that, in Bacillus subtilis, there is a single pathway to polyamines, starting from arginine, with agmatine as an intermediate. We first identified the structural gene of arginine decarboxylase, speA (formerly...

OBJECTIVE To describe the demographics, presentation, and outcome in patients with erythromelalgia--a rare and poorly understood clinical syndrome defined by the triad of red, hot, painful extremities. DESIGN Retrospective medical record review with follow-up by survey questionnaire. SETTING Large tertiary care medical center. SUBJECTS Patients with erythromelalgia examined at the Mayo Cl...

The primary sequence was established for two lysine tRNA isoacceptors which differ in abundance during development in Bacillus subtilis. Both tRNAs shared the same primary sequence but differed in the degree of post-transcriptional modification in the anticodon loop. The earlier eluting species, tRNA lys 1, had an unmodified C in position 32 and a mixture of N-[9-beta-ribofuranosyl) purin-6-ylc...
