Background: Intestinal atresia is a life-threatening problem requiring early active intervention. The aim of the study was to compare management outcomes between Duodenal-Atresia (DA) and Jejunoileal-Atresias (JIA). The secondary objective was to analyse tapering enteroplasty versus end-to-end anastomosis in JIA. Materials and Methods: Retrospective descriptive analysis of patients operated be...
DNA double-strand breaks (DSBs), which arise following exposure to a number of endogenous and exogenous agents, can be repaired by either the homologous recombination (HR) or non-homologous end-joining (NHEJ) pathways in eukaryotic cells. A vital step in HR repair is DNA end resection, which generates a long 3' single-stranded DNA (ssDNA) tail that can invade the homologous DNA strand. The gene...
Evaluation for cracks associated with ultrasonic root-end preparation of gutta-percha filled canals.
Many clinicians use ultrasonics for root-end preparations. The purpose of this study was to evaluate resected root-end surfaces of bilaterally matched human teeth for cracks before and after ultrasonic root-end preparation. Twenty matched pairs of extracted single rooted teeth were divided into two experimental groups. In group 1, root-end resection was performed on uninstrumented teeth. In gro...
DNA double-strand breaks (DSBs) are highly hazardous for genome integrity, because failure to repair these lesions can lead to genomic instability. DSBs can arise accidentally at unpredictable locations into the genome, but they are also normal intermediates in meiotic recombination. Moreover, the natural ends of linear chromosomes resemble DSBs. Although intrachromosomal DNA breaks are potent ...
