Oxide heterointerfaces often trigger unusual electronic properties that are absent in respective bulks. Here, direct evidence is offered for spontaneously assembled local structural distortions in a single-phase bulk, which confine electrons to within an atomic layer with notable orbital reconstruction and coupling, close the forbidden band, induce a ferromagnetic ordering, ...

Two experiments investigated category inference when categories were composed of correlated or uncorrelated dimensions and the categories overlapped minimally or moderately. When the categories minimally overlapped, the dimensions were strongly correlated with the category label. Following a classification learning phase, subsequent transfer required the selection of either a category label ...

To the Editor: Olesen et al. (Aug. 16 issue)(1) report that in their study, warfarin treatment was associated with a decreased risk of thromboembolic events among patients requiring renal-replacement therapy. In contrast, three large registry studies concluded that in patients with atrial fibrillation who were undergoing hemodialysis, warfarin was associated ...

KEY MESSAGE : We showed that rice prolamin polypeptides formed ER-derived PBs in transgenic rice calli, and that this heterologous transgene expression system is suitable for studying the mechanism of rice PB-I formation. Rice prolamins, alcohol-soluble seed storage proteins, accumulate directly within the rough endoplasmic reticulum (ER) lumen, leading to ...

We report two cases of lymphomatoid papulosis (LyP) occurring in conjunction with B-cell lymphoproliferative malignancies where the LyP was exacerbated during rituximab (anti-CD20 antibody)-based therapy. We postulate that the altered B-cell cytokine milieu acted to allow an exacerbation of the patient's concomitant T-cell disease and discuss the possible mechanisms by ...

3-Hydroxypropionic acid (3-HP) is a commercially important platform chemical from which a panel of chemicals can be generated. Klebsiella pneumoniae has been regarded as a promising host strain in glycerol-based 3-HP production for its exceptional ability to metabolize glycerol. Since the glycerol dissimilation mechanism governs the carbon flux distribution from ...

The brain and meningeal spaces are protected from bacterial invasion by the blood brain barrier, formed by specialized endothelial cells and tight intercellular junctional complexes. However, once in the bloodstream, N. meningitidis crosses this barrier in about 60% of the cases. This highlights the particular efficacy with which N. meningitidis ...

The periosteum, a thin, fibrous tissue layer covering most bones, resides in a dynamically loaded environment. The periosteum also provides a niche for mesenchymal stem cells. The mechanics of periosteum vary greatly between species and anatomical locations, indicating the specialized role of periosteum as bone's bounding membrane. Furthermore, periosteum exhibits ...

Although chloroplast transcriptional and translational mechanisms were derived originally from prokaryote endosymbionts, chloroplasts retain comparatively few genes as a consequence of the overall transfer to the nucleus of functions associated formerly with prokaryotic genomes. Various modifications reflect other evolutionary shifts toward eukaryotic regulation such as posttranscriptional transcript cleavage with individually ...
