Survey of the genus Bursaphelenchus Fuchs, 1937 (Nematoda: Aphelenchoididae) in...
Calin, M; Vieira, Paulo; Costache, C; Braasch, H; Gu, J; Wang, J; Mota, ManuelAn overview of the occurrence of species of the genus Bursaphelenchus in Romania is presented. The data is based on recent surveys conducted for the first time throughout the country, to monitor and evaluate the potential entry of the pine wood nematode, Bursaphelenchus xylophilus. Wood samples were collected from declining trees, woodprocessing companies and imported wood packaging material. Of the 895 wood sa...
The effect of down-regulation of Smad3 by RNAi on hepatic stellate cells and a ...
Wang,Z.R.; Wang,J.H.; Hu,C.L.; Cao,W.G.; Shen,X.J.; Wu,M.Y.; Shen,L.; Wu,S.L.Searching for effective Smad3 gene-based gene therapies for hepatic fibrosis, we constructed siRNA expression plasmids targeting the rat Smad3 gene and then delivered these plasmids into hepatic stellate cells (HSCs). The effect of siRNAs on the mRNA levels of Smad2, Smad3, Smad4, and collagens I-α1, III-α1 and IV-α1 (Colα1, Col3α1, Col4α1, respectively) was determined by RT-PCR. E...
Primary mechanism of apoptosis induction in a leukemia cell line by fraction FA...
Gao,L.; Sun,Y.; Chen,C.; Xi,Y.; Wang,J.; Wang,Z.Agaricus blazei Murill is a native Brazilian mushroom which functions primarily as an anticancer substance in transplanted mouse tumors. However, the mechanism underlying this function of A. blazei Murill remains obscure. The present study was carried out to investigate the effect of fraction FA-2-b-ß, an RNA-protein complex isolated from A. blazei Murill, on human leukemia HL-60 cells in vitro. Typical apoptot...
Near-band-edge slow luminescence in nominally undoped bulk ZnO
Monteiro, T.; Neves, A.J.; Carmo, M.C.; Soares, M.J.; Peres, M.; Wang, J.; Alves, E.; Rita, E.; Wahl, U.We report the observation of slow emission bands overlapped with the near-band-edge steady-state luminescence of nominally undoped ZnO crystals. At low temperatures the time-resolved spectra are dominated by the emission of several high-energy bound exciton lines and the two-electron satellite spectral region. Furthermore, two donor-acceptor pair transitions at 3.22 and 3.238 eV are clearly identified in temper...
Thalidomide protects mice against LPS-induced shock
Moreira,A.L.; Wang,J.; Sarno,E.N.; Kaplan,G.Thalidomide has been shown to selectively inhibit TNF-<!-- $MVD$:face("Symbol") --><FONT FACE="Symbol">a</font> production in vitro by lipopolysaccharide (LPS)-stimulated monocytes. TNF-<!-- $MVD$:face("Symbol") --><FONT FACE="Symbol">a</font> has been shown to play a pivotal role in the pathophysiology of endotoxic shock. Using a mouse model of LPS-induced shock, we investigated the effects of thalidomide on t...
