AIM The purpose of this in vitro study was to examine the effect of two different finishing systems on the surface roughness of different types of composite restorative materials. METHODS AND MATERIALS Thirty specimens, 8 mm in diameter and 3 mm in depth, were prepared using a microfill composite (Clearfil ST, Kuraray Co. Ltd., Osaka, Japan), a hybrid composite (Clearfil AP-X, Kuraray Co. Ltd...

This paper develops a constant amortized time algorithm to produce the cyclic cool-lex Gray code for fixed-density binary necklaces, Lyndon words, and pseudo-necklaces. It is the first Gray code for these objects that achieves this time bound. In addition to Gray code order, the algorithms can be easily modified to output the strings in co-lex order.

We prove that any full subcategory of a locally finitely presentable (l.f.p.) category having small limits and filtered colimits preserved by the inclusion functor is itself l.f.p. Here "full" may be weakened to "full with respect to isomorphisms." Further, we characterize those left exact functors T. C —» D between small categories with finite limits for which the functor /*: LEX(D,Set) —> LEX...

The effects of a similar exercise training stimulus on maximal insulin-stimulated (MIS) plasma membrane glucose transporter number and glucose transport were determined in lean and obese SHHF/Mcc-facp rats. Six-week-old lean and obese male rats were randomly divided into four groups: lean sedentary (LSed), obese sedentary (OSed), lean exercise (LEx), and obese exercise (OEx). An 8- to 12-wk tre...

The Quasi-Zenith Satellite System (QZSS) is a regional navigation satellite system transmitting navigation signals that are compatible and interoperable with GPS, as well as transmitting augmentation signals that carry bias correction messages. The L-band Experimental (LEX) signal on the E6b frequency delivers correction messages – such as orbits and clock information, which enable Precise Poin...

Pharmacokinetic and biodistribution studies were conducted in rats on a novel serine protease inhibitor, LEX 032, that was radiolabeled with 131I by the Bolton-Hunter reagent. LEX 032, a genetically engineered recombinant human nonglycosylated serpin, has been shown to have antiinflammatory properties in a number of animal models of inflammation and reperfusion injury. When 131I-LEX 032 was inj...

Monoclonal antibodies (MAbs) specific for Lewis X (Lex) reacted with whole cells of Helicobacter pylori NCTC11637, UA799, UA802, UA825, UA861, UA1182, and UA1206 in immunoelectron microscopy and enzyme-linked immunosorbent assay (ELISA) experiments. These MAbs have documented specificity to Lex, whereas MAbs for Lea and Leb were negative in both immunoelectron microscopy and ELISA. H. pylori co...
