In this study, the transcriptomes of 6-month-old moderate drought stressed and control G. uralensis root (the relative water content in soil was 40%-45% and 70%-75%, respectively) were sequenced using Illumina HiSeq 2000.

[Effects of storage time on quality of Desmodium styracifolium seeds].

The dynamic changes of germination percentage, germination potential, thousand-seed weight, antioxidase activity in Desmodium styracifolium seeds with different storage time were tested, and electrical conductivity, contents of soluble sugar, soluble protein, starch in seed leach liquor were also determined in order to reveal the mechanism of seed deterioration. The results as the following. (1) The germination percentage, germination potential and thousand-seed weight of D.

Insulin upregulates the expression of epithelial sodium channel in vitro and in a mouse model of acute lung injury: role of mTORC2/SGK1 pathway.

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are characterized by proteinaceous pulmonary edema and severe arterial hypoxemia with a mortality of approximately 40%. Stimulation of epithelial sodium channel (ENaC) promotes Na(+) transport, a rate-limiting step for pulmonary edema reabsorption. Insulin is known to participate in the ion transport; however, its role in pulmonary edema clearance and the regulatory mechanism involved have not been fully elucidated.

[Health risk assessment of heavy metals in atmospheric dust of Qingdao City].

Based on the 89 atmospheric dust samples and soil samples that were collected around Qingdao, we tested and analyzed the contents of Cd, Cr, Cu, Hg, Ni, Pb, Zn. Based on these analysis results, the risk of heavy metals in atmospheric dusts to human health were assessed by using the US EPA Health Risk Assessment Model. Analysis showed that the average contents of Cd, Cr, Cu, Hg, Pb, Zn in the atmospheric dust of Shinan, Shibei and Laoshan districts were the highest.

[Analysis of quality variation and genetic diversity of Desmodium styracifolium from different provenances].

Objective: To explore the quality variation and genetic diversity of Desmodium styracifolium from different provenances, and lay a foundation for rational exploitation on germplasm resources and fine variety breeding of D. styracifolium.

Method: Amplified fragment length polymorphism (AFLP) markers were developed to analyze genetic diversity in D.

[Cloning and expression regulation of 1-deoxy-D-xylulose-5-phosphate reductoisomerase cDNA from Alpinia officinarum].

The rhizome of Alpinia officinarum is a widely used Chinese herbal medicine. The essential oil in A. officinarum rhizome is mainly composed of 1, 8-cineole and other monoterpenes, as the major bioactive ingredients.

[Roles of glucosinolates in the interrelationships between Brassicaceae plants and insects: a review].

Glucosinolates (GS) are the important secondary metabolites of Brassicaceae plants, playing an important role in regulating the interrelationships between Brassicaceae plants and insects. GS can protect Brassicaceae plants against euryphagous herbivorous pests because of the toxicity of GS and their breakdown products. However, oligophagous pests which have evolved manifold metabolic pathways to cope with the defensive compounds depended fully on GS and their volatile breakdown products for host-plant recognition and orientation.

Cloning and expression of 1-aminocyclopropane-1-carboxylate oxidase cDNA induced by thidiazuron during somatic embryogenesis of alfalfa (Medicago sativa).

Embryogenic callus (EC) induced from petioles of alfalfa (Medicago sativa L. cv. Jinnan) on B5h medium turned green, compact and non-embryogenic when the kinetin (KN) in the medium was replaced partially or completely by thidiazuron (TDZ).

QTL mapping for test weight by using F(2:3) population in maize.

Test weight is an important trait in maize breeding. Understanding the genetic mechanism of test weight is important for effective selection of maize test weight improvement. In this study, quantitative trait loci (QTL) for maize test weight were identified.

Mobilization of Peripheral Blood Stem Cells Using Regimen Combining Docetaxel with Granulocyte Colony-stimulating Factor in Breast Cancer Patients.

Objective: To evaluate the effectiveness and safety of the mobilization of peripheral blood hematopoietic stem cells by combining docetaxel with granulocyte colony-stimulating factor (G-CSF) in breast cancer patients.

Methods: A total of 57 breast cancer patients were treated with docetaxel 120 mg/m(2). When the white blood cell (WBC) count decreased to 1.

[Community structure and time-space distribution characteristic of airborne fungi in a municipal landfill site].

In order to determine the community structure and time-space distribution characteristics of airborne fungi in waste landfill sites, supervisory points were set in sanitary landfill area, leachate treatment area and living area in a Waste Sanitary Landfill Site in Beijing. Airborne fungi were collected by Andersen six stages sampler, and the study on the community structure and distribution of airborne fungi was carried out systematically. The results show that fifteen genera of culturable fungi are identified (exclusion Non-sporing), Cladosporium, Aspergillus, Penicillium and Non-sporing are the dominant genera.

The resonance light scattering (RLS) technique and UV-Vis absorption spectra were applied to the investigation of the interaction between atrazine and bovine serum albumin(BSA). Under acidic conditions, the formation of atrazine-BSA supermolecule by Van der Waals force and N/O--H..

[Study on the resonance scattering light spectra of atrazine-RNA and its analytical application].

The Resonance Light Scattering (RLS) spectra of atrazine with yeast ribonucleic acid (yRNA) had been studied. At pH 1.50, the enhanced RLS of atrazine-yRNA system is characterized by the maximum scattering peaks at 320 nm and the RLS intensity is proportional to the concentration of yRNA.

Influence of CaNa2 EDTA on topical 5-aminolaevulinic acid photodynamic therapy.

Background: We assessed whether the CaNa2 EDTA could improve the accumulation of protoporphyrin IX (PpIX) and photosensitisation in HEp-2 cells as well as the depth of treatment of skin cancers on the topical 5-Aminolaevulinic acid (5-ALA) PDT.

Methods: HEp-2 cells were incubated with 5-ALA (0-1 mmol/L) and CaNa2EDTA (0-1 mmol/L) for 4 hours, intracellular protoporphyrin IX content was quantified by extraction, and cell viability was assessed by use of the methyl-tetrazolium (MTT) assay four hours after exposure to light. In comparison with the pictures before and after treatment, depth of treatment could be determined using a Acuson Sequioa 512 phase-array system in paired experiments.
