We have directly isolated clonogenic human central nervous system stem cells (hCNS-SC) from fresh human fetal brain tissue, using antibodies to cell surface markers and fluorescence-activated cell sorting. These hCNS-SC are phenotypically 5F3 (CD133) ؉ , 5E12 ؉ , CD34 ؊ , CD45 ؊ , and CD24 ؊/lo . Single CD133 ؉ CD34 ؊ CD45 ؊ sorted cells initiated neurosphere cultures, and the progeny of clonogenic cells could differentiate into both neurons and glial cells. Single cells from neurosphere cultures initiated from CD133 ؉ CD34 ؊ CD45 ؊ cells were again replated as single cells and were able to reestablish neurosphere cultures, demonstrating the self-renewal potential of this highly enriched population. Upon transplantation into brains of immunodeficient neonatal mice, the sorted͞expanded hCNS-SC showed potent en-

Research paper thumbnail of The effect of inbreeding on early growth of Acacia mangium in Vietnam

Seedlings were raised and planted out in a field trial at Ba Vi in northern Vietnam. The inbreeding status (self-fertilized or outcrossed) of most of the seedlings was determined by DNA analysis. Heights were measured at 12 and 18 months, and diameter at breast height (dbh) at 18 months. There were significant differences in growth between the six orchard sources at 18 months. Progeny from two orchards based primarily on Papua New Guinea (PNG) provenances with high levels of outcrossing displayed the best growth, with mean heights of 3.1 m at 18 months, while an orchard also based primarily on PNG provenances but with predominantly selfed progeny, and another orchard based on Queensland provenances with 51% selfed progeny, displayed the poorest growth (mean heights of 2.0 m and 2.2 m respectively). Analysis of variance established that within the 32 families that included both selfed and outcrossed individuals, self-fertilized individuals were significantly (P < 0.001) slowergrowing than were outcrossed individuals, with selfs on average 15 % smaller in mean height and 16 % smaller in mean dbh at age 18 months, relative to outcrosses. The results demonstrate the need to minimise selfing in operational seed production for A. mangium plantations.

In this paper we investigated: (i) the synthesis and kinetics of finely dispersed AgNPs in a biocompatible chitosanderived polysaccharide solution; (ii) the antibacterial activities toward both gram-(Escherichia coli and Pseudomonas aeruginosa) and gram+ bacteria (Lactobacillus fermentum, Staphylococcus aureus and Baciilus subtilis) and yeast (Candida albicans) of the obtained AgNPs; and (iii) in vitro cytotoxicity against
