Five ballistoconidiogenous yeast strains, isolated from plant leaves at Cuc Phuong National Forest of Ninh Binh, Vietnam, were assigned to the genus Kockovaella based on morphological and chemotaxonomical characteristics. They represent four new species based on analyses of 18S rDNA sequence, sequences of internal transcribed spacer regions, and DNA-DNA reassociation experiments. Four new speci...

Sawflies are important pests of various plant species. Diprion pini (L.) and Neodiprion sertifer (Geoffroy) (Hymenoptera: Diprionidae) are two of the most important sawfly pests in Italy, and both species are parasitized by the hymenopteran parasitoid Dahlbominus fuscipennis (Zetterstedt). Bacterial endosymbionts are currently studied for their high potential in strategies of biocontrol in a nu...

We herein report the design of a dumbbell-shaped DNA probe that integrates target-binding, amplification and signaling within one multifunctional design. The dumbbell probe can initiate rolling circle amplification (D-RCA) in the presence of specific microRNA (miRNA) targets. This D-RCA-based miRNA strategy allows quantification of miRNA with very low quantity of RNA samples. The femtomolar sen...

Five genera and 26 species belonging to two subfamilies Arteminae Simon, 1893 (one genus and one species) and Pholcinae C.L. Koch, 1850 (four genera and 25 species) are reported from northern Vietnam, including 19 new species of three genera: Belisana babensis sp. nov. (male, female; Bac Kan), B. cheni sp. nov. (male, female; Bac Kan), B. clavata sp. nov. (male; Ha Giang), B. curva sp. nov. (ma...

Background: Geographical Information System is a new tool in environmental epidemiology that makes the opportunity of visualization and analysis of spatial data. The aim of this study was to determine the geographic variation of low birth weight using geographic information system in order to evaluate the efficacy of primary health care and health information system. Methods: Low birth weight r...
