Among the isolates, several oligostilbenoids, including (-)-hopeaphenol (3) and (+)-isohopeaphenol (4), showed inhibitory effects on plasma triglyceride elevation at a dose of 200 mg/kg p.o. and pancreatic lipase inhibitory activity (IC50 = 32.9 and 26.5 mu M, respectively).”
“Post-transplant lymphoproliferative disorder (PTLD) is a spectrum of major, life-threatening lymphoproliferative diseases occurring JNK-IN-8 in the post-transplant setting. The majority of PTLD

is of B-cell origin and is associated with several risk factors, the most significant being Epstein-Barr virus (EBV) infection. EBV’s in vitro transforming abilities, distinctive latency, clonality within the malignant cells and response to targeted therapies 4SC-202 in vivo implicate a critical role in the biology of PTLD. This minireview focuses on EBV-related PTLD pathogenesis, in particular the interplay between aspects of the EBV life cycle and latency with nonviral

factors resulting in the wide spectrum of histology and clinical presentations encountered in PTLD. With the increased prevalence of transplantation a rise in the incidence of PTLD may be expected. Therefore the importance of laboratory and animal models in the understanding of PTLD and the development of novel therapeutic approaches is discussed.”
“Anisotropic magnetoresistance (AMR) and Hall effect have been studied for the (110)-oriented Nd0.48Sr0.52MnO3 film. The most remarkable results are the significant enhancement of the AMR accompanying the orbital ordering and the appearance of four-fold symmetry of the AMR along the [1-10] direction. Analysis of the Hall data indicates the absence of any visible increase in spin-orbit coupling corresponding to

the AMR growth. This suggests a different mechanism for the AMR Poziotinib mouse of Nd0.48Sr0.52MnO3 from that of the conventional ferromagnetic metals/alloys. (C) 2011 American Institute of Physics. [doi:10.1063/1.3657845]“
“Enzymatic fingerprinting of polysaccharides from Dendrobium officinale was studied and applied to authenticate Dendrobium species. Results showed that Dendrobium officinale species from Anhui province, Fujian province, Yunnan province, Guangdong province and Guangxi province of China, could be identified by polysaccharide analysis using carbohydrate gel electrophoresis (PACE). However, the fingerprints of Dendrobium officinale from Jiangxi province, Hu’nan province and Wenzhou, Yandangshan and Fuyang in Zhejiang province were very similar. As far as the fingerprints of different Dendrobium species were concerned, the differences between Dendrobium officinale, Dendrobium huoshanense, Dendrobium moniliforme, Dendrobium devonianum, Dendrobium aphyllum, Dendrobium wilsonii and Dendrobium crystallinum were obvious.
