This contribution addresses the relationships between the structure and gas transport properties of nanoporous thermostable cyanate ester resins (CERs) derived from polycyclotrimerization of 1,1'-bis(4-cyanatophenyl)ethane in the presence of 30 or 50 wt% of inert high-boiling temperature porogens (i.e., dimethyl- or dibutyl phthalates), followed by their quantitative removal. The nanopores in t...

  Objective(s): Renal ischemia reperfusion (IR) contributes to the development of acute renal failure (ARF). Oxygen free radicals are considered to be principal components involved in the pathophysiological tissue alterations observed during renal IR. The purpose of this study was to investigate the effect of co-administration of melatonin (MEL) and erythropoietin (EPO), potent antioxidant and ...

The aim of the present study was to investigate the effects of the surface characteristics of nanoporous titanium oxide films, formed by anodization on Ti-24Nb-4Zr-8Sn (Ti2448) alloy, on the early adhesion of osteoblast-like MG-63 cells. Nanoporous titanium oxide films with two different pore sizes (30 and 90 nm) were formed by anodization in NH4F solution on Ti2448 alloy. The surface roughness...

Melamine (Mel) was used as host matrix for liquid nitroglycerin (NG), to prepare Mel/NG solid powdered compounds containing up 45 wt% of this explosive. The two preparation processes purpose consisted in evaporating a solution both components, either ambient conditions or under reduced pressure by the Spray Flash-Evaporation (SFE) process. In materials, amorphous is distributed crystallized mel...

To search for a possible role for peripheral-type benzodiazepine receptors (PBR) during erythroid differentiation, we cloned the PBR isoquinoline carboxamide-binding protein (PBR/IBP), an 18-kDa protein on PBR, from a mouse erythroleukemia (MEL) cell cDNA library. Sequence analysis revealed that PBR/IBP comprises 169 amino acid residues (M(r) 18,828), and has a high homology with PBR/IBP from o...
