The selected waterborne polyurethanes showed a high effectiveness in the protection of paper-based materials when they were submitted

to the enzymatic attack. Indeed, their presence delayed the destruction of the cellulose matrix and the release of both soluble sugars and paper additives. (C) 2009 Wiley Periodicals, Inc. J Appl Polym Sci 113: 2030-2040, 2009″
“Objective: The progression of diabetes is associated with profound endothelial dysfunction. SU5416 ic50 We tested the hypothesis that cellular stress would be detectable in ECs retrieved from arterial and venous vessels of diabetic mice.

Method: We describe a method for direct isolation of well-characterised aortic and venous ECs from mice in which cells are not subjected

to propagation in culture.

Results: Gene expression profiling, confirmed by real-time PCR, revealed a progressive increase in markers of injury within two main gene families, LEE011 EC activation and EC apoptosis, in aortic and venous ECs recovered from diabetic versus non-diabetic mice. In short-term diabetes, IIIb mRNA transcripts were higher in aortic and venous ECs of diabetic mice versus controls. In long-term diabetes, casp-I mRNA transcripts were higher in aortic and venous ECs of diabetic mice versus controls.

Conclusion: These data suggest that diabetes imparts diffuse endothelial perturbation in the arterial and venous endothelium.”
“High-performance liquid chromatography (HPLC) was employed in a fingerprint analysis of Radix astragali. A characteristic HPLC profile of known Radix astragali samples collected from five primary habitats in China was established by evaluating 15 samples with chemometric methods, including similarity evaluation, hierarchical cluster analysis (HCA), principal component analysis (PCA) and discriminant analysis (DA). The feasibility and advantages of employing chromatographic fingerprinting combined with chemometric methods were investigated and demonstrated in the evaluation

of Radix astragali for the first time. The results AZD3965 nmr showed that the chromatographic fingerprint combined with chemometric methods could efficiently distinguish Radix astragali from various areas and provide quality control in the quantitative analysis.”
“In this article, a novel solid-solid phase change heat storage material was synthesized via a two-step condensation reaction of high molecular weight poly (ethylene glycol) (PEG4000) with poly(vinyl alcohol) (PVA) and 4,4′-diphenylmethane diisocyanate (MDI). To characterize the resulting product in comparison with pristine PEG4000, Fourier transform infrared spectroscopy, differential scanning calorimetry, thermogravimetric analyses, and polarization optical microscopy measurements were employed to investigate functionality, thermal properties, and crystalline behavior.
