to compare three various methods in the diagnosis of dentinal cracks formed in the apical third after root resection.one hundred extracted human maxillary central incisors were selected. the root canals were prepared with step-back technique. then 3mm from the apical end of all roots was cut perpendicular to the long axis of the tooth. the apical end of each root was evaluated to make sure ther...
Tailoring the blue photoluminescence (PL) in Al-doped ZnO (AZO)/TiO 2 heterostructures is demonstrated by a controlled induction of shallow defect centers 50 keV Ar + -ions. This established combination temperature dependent PL and electron paramagnetic resonance spectroscopy. The dominant blue-violet an as-grown sample comprises near band-edge emission, along with peak associated radiative rec...
The gene for the Eco RV methylase has been cloned into a plasmid under control of the strong lambda PL promoter and overexpressed in E. coli. This plasmid, pVIC1, gives reliable overexpression of the methylase at levels of about 20% of total protein. Maximum yields of soluble protein are achieved after about 6 hours of induction. If the cells are harvested later than this much of the enzyme is ...
Hydride attack at a ferric heme-NO to give an Fe-HNO intermediate is a key step in the global N-cycle. We demonstrate differential reactivity when six- and five-coordinate ferric heme-NO models react with hydride. Although Fe-HNO formation is thermodynamically favored from this reaction, Fe-H formation is kinetically favored for the 5C case.
OBJECTIVE The roles of individual types of cerebral cells in contributing to brain edema are undefined. The objective of this study was to determine the role of cerebral cell-column chromatography in quantifying cell volumes of individual cerebral cell lines, under chemically-induced anoxia/re-oxygenation (A/R). METHODS Cerebral endothelial cells (4 experiments) or type II astrocytes (4 exper...
