“Plastin 3 (PLS3), a protein involved in
the formation of filamentous actin (F-actin) bundles, appears to be important in human bone health, on the basis of pathogenic variants in PLS3 in five families with X-linked osteoporosis and osteoporotic fractures that we report here. The bone-regulatory properties of PLS3 were supported by in vivo analyses in zebrafish. Furthermore, in an additional five families (described in less detail) referred for diagnosis or ruling out of osteogenesis imperfecta type I, a rare variant (rs140121121) in PLS3 was found. This variant was also associated with a risk of fracture among elderly heterozygous women that was two times as high as that among noncarriers, which indicates that genetic variation in PLS3 is a novel etiologic factor involved in common, multi-factorial osteoporosis.”
“In this work the recombinant human
bone morphogenetic protein 2 (rhBMP-2) gene was cloned from MG-63 cells by RT-PCR and the protein was expressed in Escherichia cob expression system purified by Ni-NTA column under denaturing conditions and refolded at 4 degrees C by urea gradient dialysis We found that the www.selleckchem.com/products/azd2014.html protein refolding yield was increased with the increase of pH value from pH 6 0 to pH 90 The yield was 42% and 96% at pH 74 and pH 9 0 respectively while that at pH 60 was only 3 4% The cell culture results showed that the rhBMP-2 refolded at pH 74 urea gradient dialysis had higher biological activity for MG-63 cell proliferation and differentiation than that refolded at pH 9 0 since pH 7 4 is closer to the conditions PDK3 in vivo leading to the formation of Miners through the interchain disulfide bond Moreover the biological activity for MG-63 was promoted with the increase of rhBMP-2 concentration in the cell culture medium This
work may be important for the in vitro production and biomedical application of rhBMP-2 protein (C) 2010 Elsevier Inc All rights reserved”
“The analytical and clinical performance of a new rapid immunochromatography test, the SD Bioline Norovirus test, was evaluated for the detection of human norovirus in fecal specimens. The analytical performance studies were performed for detection limit, reproducibility, cross-reactivity, and interference. For comparison, 92 norovirus-positive stool samples and 126 norovirus-negative samples for which the results were confirmed by 2 different real-time PCR kits were used. The rapid immunochromatography test detected the equivalent of 4.48 x 10(6) copies/mL of the norovirus genome in stool samples. On performing the repeatability/reproducibility test, samples above this concentration all provided positive results (100%) and 97.8% of the samples slightly below this concentration (2.45 x 10(6) copies/mL) provided negative results. No cross-reactivity or interference was detected.
