Heat treatment of nanoparticles could induce the surface rearrangement for more stable facet exposure induced by thermodynamics. By changing the heat treatment environment, we confirmed the correlation between the oxygen reduction activity and the effect of surface oxide and the degree of surface rearrangement of Pt nanoparticles. Native surface oxide was not a critical factor for oxygen reduct...

Note taking is a fundamental activity for learning, and many software tools which enable students to take digitized notes have been proposed. Digitized notes are advantageous because they can be easily edited, rearranged, and shared. Although many note-taking tools have been proposed, there has been little research to examine the effect of note annotation and rearrangement with a digitized tool...

AS ALK and ROS1 rearrangements define relatively small subsets of patients with NSCLC. ALK rearrangement is identified in 3% to 5% of patients, whereas ROS1 rearrangement is identified in approximately 1% of patients. Although the percentages are small, the total number of patients diagnosed each year with advanced NSCLC is very large, so small percentages still translate into a sizable number ...

To determine if circulating Sezary cells can be classified as reactive or neoplastic based on the ability to detect the presence or absence of clonal T-cell receptor beta chain (TCR-beta) gene rearrangements by Southern blot analysis, we evaluated the peripheral blood of 25 patients: 11 patients with Sezary syndrome (SS), 11 with benign inflammatory dermatoses (BID), and three normal controls. ...

We have shown previously that a mutation of the KI-KII site immediately 5' to J(kappa)1 on the mouse immunoglobulin light chain kappa locus reduces the rearrangement level in cis, although it does not affect transcription. Here we deleted by homologous recombination in mouse embryonic stem cells a 4-kb DNA fragment, located immediately upstream of the KI-KII element, which contains the promoter...

The t(11;14)(q13;q32) translocation and its molecular counterpart bcl-1 rearrangement are frequently associated with mantle cell lymphomas (MCLs) and only occasionally with other variants of B-cell lymphoid malignancies. This translocation seems to activate the expression of PRAD-1/cyclin D1 gene located downstream from the major breakpoint cluster region of this rearrangement. However, the pos...

The cell behaviour and motility underlying cell rearrangement during gastrulation in amphibian and sea-urchin embryos are discussed. In particular, the cell behaviour of deep (non-epithelial) and epithelial cell populations that undergo cell rearrangement is compared and contrasted. Deep cell rearrangement in Xenopus laevis involves both convergence of cells towards the future dorsal midline an...

The Ag receptor of the T lymphocyte is composed of an alphabeta heterodimer. Both alpha- and beta-chains are products of the somatic rearrangement of V(D)J segments encoded on the respective loci. During T cell development, beta-chain rearrangement precedes alpha-chain rearrangement. The mechanism of allelic exclusion ensures the expression of a single beta-chain in each T cell, whereas a large...
