Control of transcriptional elongation and cotranscriptional histone modification by the yeast bur kinase substrate spt5... Among these factors are the polymerase-associated factor (PAF) complex, which associates with RNAPII, and several cyclin-dependent kinases, including positive transcription elongation factor b (P-TEFb) in humans and BUR kinase (Bur1–Bur2) and C-terminal domain (CTD) kinase 1 (CTDK1) in Saccharomyces cerevisiae....
An improved cvdd bur used in ultrasonic dental system for enamel removal AbstractThe aim of this paper is to increase enamel removal rate of dental diamond bur used in ultrasonic system so as to realize and promote its clinical applications....
Effect of diamond bur cutting efficacy on dentin bond strengths of different bonding systems"nBackground and Aim: As composite-dentin bond strength is affected by cavity preparation and the bond strength of composite resin to new and used bur prepared dentin has not yet been evaluated, this study evaluated the effects of cutting dentin with different cutting efficacy (new and used) of burs on composite-dentin shear...
The chamfer finish line: preclinical student performance using different bur designsAbstract: The primary purposes of this investigation were to evaluate sophomore dental student performance in the production of a chamfer finish line using two diamond bur types—a round-ended bur and a torpedo-shaped bur—and to gain student feedback about their preferences for bur type....
