The templated CuPc films were found to grow on both the (110) and (102) plane of the alpha-PTCDA layer, indicating the intermolecular pi-pi interaction is strong enough to induce templating even on the underlying layer which is tilted at an angle of 25 degrees from the substrate surface as well as on the surface-parallel SBE-β-CD layer. In contrast to

the large growth exponent (beta) values for other single layer molecular thin films, a significantly small beta value of 0.17 +/- 60.06 was obtained on the PTCDA/CuPc heterolayer thin film system. The XRD and scaling behavior studies suggest that this relatively slow surface roughening can be rationalized by the lack of surface parallel crystalline ordering at the initial stage of CuPc film growth on the

PTCDA layer. (C) 2011 American Institute of Physics. [doi:10.1063/1.3553884]“
“The authors report an 8-year-old girl with refractory status epilepticus due to hypertensive encephalopathy, secondary to end-stage renal disease. Brain magnetic resonance imaging (MRI) in the acute phase showed striking hyperintensities in the brain stem and medial thalamus along with subtle cortical lesions. After successful control of hypertensive crisis and status epilepticus, the patient recovered to her baseline. Near total resolution of the SNX-5422 cost lesions was noted on follow-up imaging performed 9 days later. Predominant brainstem involvement as a feature of posterior reversible encephalopathy syndrome

due to hypertensive crisis is extremely rare in children and has not been well documented.”
“Purpose: Ionising radiation (IR) can evoke a series of biochemical events inside the cell. However, whether IR can directly induce endoplasmic reticulum (ER) stress is not clear. In our previous study, we found that there might be a causative link DZNeP mw between IR and ER stress. In this study, we further characterised the type of ER stress induced by IR.

Materials and methods: Rat intestinal epithelial cells IEC-6 were irradiated at a dose of 10 Gy, and total RNA and proteins were harvested at indicated time points. The mRNA and protein expression of immunoglobulin heavy chain binding protein (BiP) and glucose regulated protein 94 (GRP94) was detected along with proteins associated with ER stress signal pathways.

Results: Our results indicated that IR induced up-regulation of ER stress marker including BiP and GRP94 at protein and mRNA levels in IEC-6 cells.
