Changes in mechanical properties of seven light-cured composite resins after thermal cycling.

Objective: To examine the changes of the mechanical properties of 7 different light-cured composite resins after thermal cycling and the correlations between these properties.

Methods: Seven different light-cured composite resins, including 2 microfilled composites (A110:AH and ESTELITE :ET), 3 microhybrid composites (AELITE:AT, Z250:ZS, and CharmFil plus:CP), and 2 nanohybrid composites (Z350:ZH and Grandio:GD), were prepared into test specimens with a diameter of 12 mm and a thickness of 1.0 mm.

Development of strain-specific PCR primers based on a DNA probe Fu12 for the identification of fusobacterium nucleatum subsp. nucleatum ATCC 25586T.

The objective of this study was to assess the strain-specificity of a DNA probe, Fu12, for Fusobacterium nucleatum subsp. nucleatum ATCC 25586T (F. nucleatum ATCC 25586T), and to develop sets of strain-specific polymerase chain reaction (PCR) primers.

Karyotype analysis of a Korean cucumber cultivar (Cucumis sativus L. cv. Winter Long) using C-banding and bicolor fluorescence in situ hybridization.

An intensive karyotype analysis of a Korean cucumber cultivar (Cucumis sativus L. cv. Winter Long) was carried out with three different methods.
