Goniothalamusflagellistylus Tagane & V. S. Dang (Annonaceae), a new species from Mt. Hon Ba, Vietnam.

A new species, Goniothalamusflagellistylus Tagane & V. S. Dang, sp.

Simultaneous silencing of VEGF and KSP by siRNA cocktail inhibits proliferation and induces apoptosis of hepatocellular carcinoma Hep3B cells.

Background: Vascular endothelial growth factor (VEGF) is involved in the growth of new blood vessels that feed tumors and kinesin spindle protein (KSP) plays a critical role in mitosis involving in cell proliferation. Simultaneous silencing of VEGF and KSP, an attractive and viable approach in cancer, leads on restricting cancer progression. The purpose of this study is to examine the therapeutic potential of dual gene targeted siRNA cocktail on human hepatocellular carcinoma Hep3B cells.

Gekko aaronbaueri, a new gecko (Squamata: Gekkonidae) from central Laos.

A new species of the genus Gekko Laurenti is described from central Laos. The species is distinguished from its congeners by its moderate size, i.e.

Microcystin uptake and biochemical responses in the freshwater clam P. exposed to toxic and non-toxic : Evidence of tolerance to cyanotoxins.

We investigated the accumulation and adverse effects of toxic and non-toxic in the edible clam . Treated clams were exposed to toxic at 100 μg of MC (microcystin)-LR L for 10 days. The experimental organism was then placed in toxin-free water and fed on non-toxic for the following 10 days for depuration.

A new species of Hemiphyllodactylus Bleeker, 1860 (Squamata: Gekkonidae) from Ba Na-Nui Chua Nature Reserve, Central Vietnam.

A new species of the gekkonid Hemiphyllodactylus banaensis sp. nov. is described from Ba Na-Nui Chua Nature Reserve in central Vietnam.

Differentiation of umbilical cord lining membrane-derived mesenchymal stem cells into endothelial-like cells.

Background: Stem cell therapy for the treatment of vascular-related diseases through functional revascularization is one of the most important research areas in tissue engineering. The aim of this study was to investigate the in vitro differentiation of umbilical CL-MSC into endothelial lineage cells.

Methods: In this study, isolated cells were characterized for expression of MSC-specific markers and osteogenic and adipogenic differentiation.

Phylogeny of the Cyrtodactylus irregularis species complex (Squamata: Gekkonidae) from Vietnam with the description of two new species.

The number of described species of bent-toed geckos of the Cyrtodactylus irregularis species complex in Vietnam has increased from one to eight in the last six years. We combined morphological and molecular analyses to explore phylogenetic relationships among all described species in the group. The phylogeny required the description of two new species, Cyrtodactylus phuocbinhensis sp.

Effects of Environmental Factors on Growth and Artemisinin Content of Artemisia annua L.

Seeds of two selected clones of Artemisia annua L., TC1 and TC2, were germinated in a greenhouse. Four-week-old seedlings from both clones were grown in the Thù Đúc province of Ho Chi Minh City on 2(nd) January 2009 and Đà Lat on 20(th) January 2009.

A new species of Gekko (Squamata: Gekkonidae) from Tà Kóu Nature Reserve, Binh Thuan Province, Southern Vietnam.

A new species of Gekko Laurenti is described from Ta Kou Mountain, an isolated granitic peak in Ta Kou Nature Reserve, Ham Thuan Nam district, Binh Thuan province, southern Vietnam. The species is distinguished from its congeners by its moderate size, with snout to vent length (SVL) reaching a maximum 107.0 mm; dorsal pattern of 5-8 white vertebral blotches between the nape and sacrum and 6-8 pairs of short white bars on the flanks; 11-14 precloacal pores in males; 14-17 longitudinal rows of smooth dorsal tubercles; and 18-20 broad lamellae beneath the fourth toe.

[Analysis of the antigenicity of the expression product of fusion antigen epitope genes of FMDV].

Aim: From the different recombinants of FMDV antigen epitope, the highest antigenicity one was selected, and that provided research foundation for making researches on FMD plant-based vaccines which could effectively induce cell immune response and be characterized by high eurytopicity.

Methods: The single-chain DNA of 5 T-cell epitope genes and 2 B-cell epitope genes were synthesized. By gene splicing by overlap extension technique, 5 T-cell epitope genes were fused together into T and 2 B-cell epitope genes were fused together into B.

Streptomyces vietnamensis sp. nov., a streptomycete with violet blue diffusible pigment isolated from soil in Vietnam.

An actinomycete, designated strain GIMV4.0001(T), was isolated from a forest soil sample in Vietnam. It produced white aerial mycelium and violet-blue diffusible pigment on Gause's synthetic agar.

[The effect of the substance exin on development of microbial infections and isolation of ethylene in plants].

Effects of Exin on infection of tomato, potato, and cabbage plants with Pseudomonas solanacearum and Erwinia carotovora and a fungus Sclerotium rolfsii were studied. The treatment of infected plants with Exin caused no significant effect on the development of the disease. Treatment with streptomycin as a standard for comparison completely inhibited the growth of these microorganisms.
