[Effects of Apelin-13 on barrier injury of human umbilical vein endothelial cells induced by LPS].

To investigate the effects of Apelin-13 on barrier function injury of human umbilical vein endothelial cells (HUVECs) induced by LPS. The HUVECs cultured were divided into 4 groups: Control group, LPS group, Apelin-13+LPS group, Apelin-13 group. HUVECs were treated by 5 μg/ml LPS for 24 h to replicate the model with endothelial barrier impaired.

[Development of resources, technologies and services at the China Zebrafish Resource Center].

With the rapid growth of the Chinese zebrafish community, there is an increasing demand for various types of zebrafish-related resources and technologies. The China Zebrafish Resource Center (CZRC, web: http://zfish.cn) was established at the Institute of Hydrobiology (IHB), Chinese Academy of Sciences (CAS) in 2012.

Ptilagrostis contracta (Stipeae, Poaceae), a New Species Endemic to Qinghai-Tibet Plateau.

A new species, Ptilagrostis contracta, endemic to Qinghai-Tibet Plateau is described and illustrated. It is distinguished from other species in Ptilagrostis by having contracted panicles, 1-geniculate awns with hairy columns and scabrous bristles and evenly pubescent lemmas. Evidence from lemma epidermal pattern, cytology and molecular phylogenetic analyses based on the nuclear ITS sequence data confirm its systematic position in Ptilagrostis.

Preparation of a new-style composite containing a key bioflocculant produced by Pseudomonas aeruginosa ZJU1 and its flocculating effect on harmful algal blooms.

A novel composite consisting of clay, bioflocculant, and inorganic flocculant was designed, and its flocculating effect on harmful algal blooms (HABs) was studied in this study. The extracellular polymeric substances (EPS), produced with a yield of 3.58±0.
