[Effect of Water Components on Aggregation and Sedimentation of Polystyrene Nanoplastics].

The aggregation and sedimentation of micro/nano-plastics significantly affect their migration and distribution in the environment. This study investigated the effects of Na and natural organic matter （NOM） on the aggregation and sedimentation of polystyrene nano-plastics （PS-NPs） in the aqueous phase. Six types of water， such as seawater， lake water， and domestic sewage， were used to evaluate the above effects and other potential influencing factors.

Alleviation of palmitic acid-induced endoplasmic reticulum stress by augmenter of liver regeneration through IP3R-controlled Ca release.

The aberrant release of Ca from the endoplasmic reticulum (ER) contributes to the onset of ER stress, which is closely related to the pathogenesis of non-alcoholic fatty liver disease. We previously reported that augmenter of liver regeneration (ALR) alleviates ER stress and protects hepatocytes from lipotoxicity. However, the link between ALR protection and the suppression of ER stress remains unclear.

Molecular characterization of a novel gene from Synechocystis sp. PCC 6803.

A novel gene slr2049 was identified in Synechococcus sp. PCC7002 by homologous alignment. The features and possible functions of slr2049 gene were predicted by bioinformatics analysis.

[GC-MS analysis on the chemical constituents of essential oil from bark of Horsfieldia hainanensis].

Objective: To analyze the constituents of the essential oil from the bark of Horsfieldia hainanensis.

Methods: The volatile oil was obtained by steam distillation. The chemical constituents were separated and identified by gas chromatography-mass spectrometry (GC-MS).

[Supercritical CO2 fluid extraction of Rosmarinus officinalis and capability of extracts eliminate OH radical].

Objective: Supercritical CO2 fluid extraction process of antioxidation active components from Rosmarinus officinalis was studied.

Method: A new extraction process of components extracted from R. officinalis by supercritical CO2 fluid extraction (SFE-CO2 ) was studied in detail.

[Transformer genes and sex determination of C. elegans and D.melanogaster].

Sex determination of Drosophila melanogaster and Caeborhabditis elegans has been known in detail. Great progress, is achieved in recent years, is the research of transformer genes, which are those of most important genes in sex determination in both species. In this paper, molecular character, genetic function and the relative genes of transformer genes are particularly described.
