BACKGROUND There are no convincing data supporting the routine use of pre-emptive therapy against HBV reactivation in various loco-regional therapies for hepatocellular carcinoma (HCC). This study investigated the incidence, severity and risk factors of HBV reactivation during loco-regional therapies. METHODS A total of 205 prospectively enrolled patients were classified in order of increasin...

Drake, John W. (University of Illinois, Urbana). Multiplicity reactivation of Newcastle disease virus. J. Bacteriol. 84:352-356. 1962.-A very weak multiplicity reactivation occurs among Newcastle disease virus particles inactivated by ultraviolet irradiation. The preliminary steps in the infection of embryonic chicken fibroblasts are complex, and their relation to multiplicity reactivation is d...

Disrupting the reactivation of hippocampal neurons during sleep impairs memory consolidation in rats. However, the functional importance of reactivation during awake states is unknown. An experiment in which awake reactivation was disrupted suggests that this phenomenon could adaptively guide behavior by linking previous learning with the current state of the world.

Several studies have demonstrated that localized heating of tree stems induces localized cambial reactivation. We analyzed by light microscopy the effects of early spring increases in ambient temperature in 2005 and 2007 on the timing of cambial reactivation and xylem differentiation in stems of two trees of a cloned deciduous hardwood hybrid poplar (Populus sieboldii Miquel. x P. grandidentata...

Murine gammaherpesvirus 68 (gammaHV68) infection of mice results in the establishment of a chronic infection, which is largely maintained through latent infection of B lymphocytes. Acute virus replication is almost entirely cleared by 2 weeks postinfection. Spontaneous reactivation of gammaHV68 from latently infected splenocytes upon ex vivo culture can readily be detected at the early stages o...

Fluids are pervasive in the Earth’s crust and saturate fractures faults. The combination of fluids gouge layers developing along faults can generate different viscosities. Such viscous were found to influence reactivation, frictional stability faults, eventually dynamics propagating earthquake ruptures. We reproduced laboratory earthquakes on analog material (PMMA) study lubricant fault stabili...

The mechanisms supporting hippocampal memory reactivation are puzzling. Reactivation occurs during ripple oscillations, yet ripples are not coordinated across regions. In this issue of Neuron, Carr et al. (2012) report that another oscillation, slow gamma, coordinates memory reactivation across the hippocampal network.

STUDY OBJECTIVES To investigate how the effects of targeted memory reactivation (TMR) are influenced by memory accuracy prior to sleep and the presence or absence of direct cue-memory associations. METHODS 30 participants associated each of 50 pictures with an unrelated word and then with a screen location in two separate tasks. During picture-location training, each picture was also presente...

UNLABELLED Latent tuberculosis infection affects one third of the world's population and can reactivate (relapse) decades later. However, current technologies, dependent on postmortem analyses, cannot follow the temporal evolution of disease. METHODS C3HeB/FeJ mice, which develop necrotic and hypoxic tuberculosis lesions, were aerosol-infected with Mycobacterium tuberculosis. PET and CT were ...

Highly microporous bio-based activated carbon fibers (ACFs) were prepared through a simple reactivation method. Sawdust, as the starting material, was liquefied and melt-spun to produce the precursor fibers. Then, the precursor fibers were activated by KOH and reactivated by steam. By varying the conditions of the two activation processes, the formation mechanism of the pore structure was studi...
