MSCs (cUCM-MSCs) were plastic adherent, spindle-shaped and fibroblast-like cells, maintaining expression of pluripotency markers such as Oct3/4, Nanog, Sox-2 and SSEA-4 as well as normal chromosomal number during a long-term proliferative culture. The cells expressed MSCs-specific surface markers, including CD44, CD90, CD105, and CD184, but did not CD29, CD33, CD34, and CD45. More importantly, cUCM-MSCs could differentiate into mesodermal (adipocyte, osteocyte and chondrocyte) and ectodermal (neuronal cell) cell lineages. These results imply that collagenase digestion would be a highly effective way to isolate multipotent MSCs in abundant amounts. (C) 2012 Elsevier Ltd. All GDC-0068 rights reserved.”
“The effect of the hybridization of short glass fibers (GFs) and talc mineral filler on the tensile mechanical performance of injection-molded propylene-ethylene copolymer composites (PP(cop)) with and without weld lines (WLs) was studied in this work. The fibrous Erastin mw reinforcement imparts high-tensile stiffness and strength to the molding but originates a highly
anisotropic composite. The negative effect of this anisotropy is even worse when WLs occur in the molding, as the high aspect ratio GFs tend to be oriented on the weak plane of the WL. Through hybridization of GF and talc, combined in different proportions, it is possible to obtain improved mechanical properties in comparison to the standard GF reinforced Pp, p composites. The combination of GF with talc was shown to be beneficial for the WL strength of PP(cop) composites, once a synergism effect was achieved with the expected optimization of the fibers/particles packing efficiency of the hybrid reinforcement. At a given constant total reinforcement concentration, the experimental data
of both tensile modulus and strength properties of the hybrid composites without WL were above the predictions derived from the estimated buy Repotrectinib rule of mixtures. (C) 2009 Wiley Periodicals, Inc. J Appl Polym Sci 114: 3592-3601, 2009″
“This paper demonstrates that rice bran hemicellulose A (RBHA), hemicellulose B (RBHB) and hemicellulose C (RBHC) have the potential for binding heavy metal ions. The quantity of metal ions bound varies from one rice bran fibre to another. As it can be inferred from the results of the study, RBHB was characterised by the highest capacity for metal ion (Pb, Cu and Cd) binding, followed by RBHC and RBHA. Binding of heavy metals to insoluble dietary fibre (RBDF) and cellulose from rice bran were found to be poor. Lignin from rice bran was the least active fraction for binding heavy metal ions.
