Changing the frequency and spectra of chromosomal aberrations in Korean patients with acute leukemia in a tertiary care hospital.

Background: Chromosomal analysis is essential for the diagnosis and risk stratification of all leukemia patients. Not surprisingly, racial differences in chromosomal aberrations (CA) in hematological malignancies could be found, and CA incidence in leukemia might change over time, possibly due to environmental and lifestyle changes. Thus, we compared the frequency and range of CA in patients with acute leukemia (AL) during two time periods (2006‒2009 vs.

Identification of oligopeptide permease (opp) gene cluster in Vibrio fluvialis and characterization of biofilm production by oppA knockout mutation.

Oligopeptides play important roles in bacterial nutrition and signaling. The oligopeptide permease (opp) gene cluster was cloned from Vibrio fluvialis. The V.
