A new species of the Asian leaf litter toad genus Smith, 1925 (Anura, Megophryidae) from northwest Guizhou Province, China.

A new species of the Asian leaf litter toad genus is described from Guizhou Province, China. Molecular phylogenetic analyses support the new species as an independent lineage deeply nested in the clade. The new species is distinguished from its congeners by a combination of the following morphological characters: body size medium (SVL 29.

A new species of the Music frog (Anura, Ranidae) from Guizhou Province, China.

The Music frog genus is widely distributed in East and South Asia. Here, a new species of the genus is described from southwestern China. Phylogenetic analyses based on the mitochondrial 16S rRNA and COI gene sequences supported the new species as a clade closely related to , , , , and .

Diversity and antimicrobial activity of culturable endophytic fungi isolated from moso bamboo seeds.

Bamboos, regarded as therapeutic agents in ethnomedicine, have been used to inhibit inflammation and enhance natural immunity for a long time in Asia, and there are many bamboo associated fungi with medical and edible value. In the present study, a total of 350 fungal strains were isolated from the uncommon moso bamboo (Phyllostachys edulis) seeds for the first time. The molecular diversity of these endophytic fungi was investigated and bioactive compound producers were screened for the first time.

Colorimetric sensing of silver(I) and mercury(II) ions based on an assembly of Tween 20-stabilized gold nanoparticles.

We have developed a rapid and homogeneous method for the highly selective detection of Hg(2+) and Ag(+) using Tween 20-modified gold nanoparticles (AuNPs). Citrate ions were found to still be adsorbed on the Au surface when citrate-capped AuNPs were modified with Tween 20, which stabilizes the citrate-capped AuNPs against conditions of high ionic strength. When citrate ions had reduced Hg(2+) and Ag(+) to form Hg-Au alloys and Ag on the surface of the AuNPs, Tween 20 was removed from the NP surface.

[Application of in situ cryogenic Raman spectroscopy to analysis of fluid inclusions in reservoirs].

Identification of salts is a principal problem for analysis of fluid inclusions in reservoirs. The fluid inclusions from deep natural gas reservoirs in Minfeng sub-sag were analyzed by in situ cryogenic Raman spectroscopy. The type of fluid inclusions was identified by Raman spectroscopy at room temperature.
