IN VITRO EVALUATION OF FORCE-EXPANSION CHARACTERISTICS IN A NEWLY DESIGNED ORTHODONTIC EXPANSION SCREW COMPARED TO CONVENTIONAL SCREWS

In vitro evaluation of force-expansion characteristics in a newly designed orthodontic expansion screw compared to conventional screws

Objective : Expansion screws like Hyrax, Haas and other types, produce heavy interrupted forces which are unfavorable for dental movement and could be harmful to the tooth DEODORANT SPORT and periodontium.The other disadvantage of these screws is the need for patient cooperation for their regular activation.The purpose of this study was to design a

Heteroduplex DNA position defines the roles of the Sgs1, Srs2, and Mph1 helicases in promoting distinct recombination outcomes.

The contributions of the Sgs1, Mph1, and Srs2 DNA helicases during mitotic double-strand break (DSB) repair in yeast were investigated using a gap-repair assay.A diverged chromosomal substrate was used as a repair template for the gapped plasmid, allowing mismatch-containing heteroduplex DNA (hDNA) formed during recombination to be monitored.Overal
