Cathepsin L-like Cysteine Proteinase Genes Are Associated with the Development and Pathogenicity of Pine Wood Nematode, .

The pine wood nematode (PWN), , is the pathogen of pine wilt disease (PWD), resulting in huge losses in pine forests. However, its pathogenic mechanism remains unclear. The cathepsin L-like cysteine proteinase (CPL) genes are multifunctional genes related to the parasitic abilities of plant-parasitic nematodes, but their functions in PWN remain unclear.

Expression Profiling of Autophagy Genes BxATG1 and BxATG8 under Biotic and Abiotic Stresses in Pine Wood Nematode Bursaphelenchus xylophilus.

The pine wood nematode (PWN), , is the pathogen of pine wilt disease (PWD) and causes huge economic losses in pine forests and shows a remarkable ability to survive under unfavorable and changing environmental conditions. This ability may be related to autophagy, which is still poorly understood in . Our previous studies showed that autophagy exists in PWN.

[A new napthalenone from roots of Rumex nepalensis].

A new napthalenone, rumexone A (1), was isolated from the roots of Rumex nepalensis. The structure of 1 was elucidated by extensive spectroscopic analyses, including 1D and 2D NMR spectra and MS data. Its cytotoxic effect was evaluated using four clinically relevant human cancer cell lines, gastric carcinoma SGC7901, breast carcinoma MDA-MB-231, lung carcinoma A549, and hepatocellular carcinoma HepG2.

Rhobupcyanoside B, A new cyanoside from Rhodiola bupleuroides.

One new cyanoside, rhobupcyanoside B (1), together with 7 known ones, was isolated from the 70% ethanol extract of the roots and rhizomes of Rhodiola bupleuroides. Their structures were determined by spectroscopic methods, including 2D NMR techniques. Compound 1 was evaluated for its inhibitory activity against α-glucosidase with IC50 value of 278.

Identification of Autophagy in the Pine Wood Nematode Bursaphelenchus xylophilus and the Molecular Characterization and Functional Analysis of Two Novel Autophagy-Related Genes, BxATG1 and BxATG8.

The pine wood nematode, Bursaphelenchus xylophilus, causes huge economic losses in pine forests, has a complex life cycle, and shows the remarkable ability to survive under unfavorable and changing environmental conditions. This ability may be related to autophagy, which is still poorly understood in B. xylophilus and no autophagy-related genes have been previously characterized.

Nutritional status of children during and post-global economic crisis in China.

Objective: To describe the impact of the global economic crisis on the nutritional status of children in China during and after the crisis.

Methods: Data from 1990 to 2010 were sourced from the National Food and Nutrition Surveillance System. Approximately 16 000 children under 5 years old were selected using a stratified random cluster method from 40 surveillance sites.

[Gender analysis on prenatal care in rural areas of Xinjiang and Anhui province].

Objective: To introduce the gender-specific view to the prenatal care and analysing the health behavior and its influencing factors.

Methods: Random sampling in cluster was used to select those study population and face to face interview was carried out at their residence in Xinjiang and Anhui province.

Results: The overall socioeconomic status of women in rural areas of Xinjiang and Anhui province was low and 93.

[The application of decision tree in the research of anemia among rural children under 3-year-old].

Objective: To study the application of decision tree in the research of anemia among rural children.

Methods: In the Enterprise Miner module of software SAS 8.2, 3000 observations were sampled from database and the decision tree model was built.
