Ab initio study of subsurface diffusion of Cu on the H-passivated Si(001) surface
(American Physical Society, 2009-10-12)
In this paper we use density-functional theory calculations to analyze both the stability and diffusion of Cu adatoms near and on the H-passivated Si 001 surface. Two different Cu sources are considered: depositing Cu ...
Cloning, purification and characterization of two components of phenol hydroxylase from Rhodococcus erythropolis UPV-1
(Springer, 2009-09-29)
Phenol hydroxylase that catalyzes the conversion of phenol to catechol in Rhodococcus erythropolis UPV-1 was identified as a two-component flavin-dependent monooxygenase. The two proteins are encoded by the genes pheA1 and ...

High Mitochondrial DNA Stability in B-Cell Chronic Lymphocytic Leukemia
(Public Library Science, 2009-11-18)
Background: Chronic Lymphocytic Leukemia (CLL) leads to progressive accumulation of lymphocytes in the blood, bone marrow, and lymphatic tissues. Previous findings have suggested that the mtDNA could play an important role ...
