Background and Aim: Preparation of tooth structure by laser systems produces a surface with different characteristics. Therefore, selecting an appropriate bonding system is necessary to achieve the maximum bond strength. The aim of this study was to compare the bond strength of Adper Single Bond 2 adhesive and Single Bond Univer-sal to dentin prepared by bur or laser. Materials and Methods: ...

in this study the uptake and metabolism of adenosine by mitochondria has been investigated. incubation of cem cells mitochondria preparation with [3h] -adenosine showed substantial uptake and metabolism of adenosine. adenosine was both anabolized to amp, adp and atp, and also catabolized to inosine. the highest concentration of metabolites in extracted mitochondria was due to amp. the mitochond...

BACKGROUND The diagnostic yield of capsule endoscopy depends on the quality of visualization of the small-bowel wall and complete passage through the small bowel. This study examined the effect of bowel preparation on the volume of intestinal content and on small-bowel transit. METHODS Sixty-one consecutive patients (34 men, 27 women; mean age 56 years, range 17-88 years) were enrolled in the...

This article presents a brief state of the art in the Swedish metal working industry regarding the production preparation process for the machine centre. The article is based on a relationship model from which a questionnaire was developed. The model incorporates the perceived preparation process efficiency, the amount of systematic preparation work, in relation to the companies’ premises as po...
