Carbon (C), nitrogen (N) and phosphorus (P) concentrations and stoichiometry play important roles in biogeochemical cycles of the ecosystems, yet it is still unclear how the allocations of C, N and P concentrations and stoichiometry among plant organs and soils related to O stress and straw return. Here, a pot experiment was conducted in open top chambers to monitor the response of C, N and P concentrations and stoichiometry of leaves, stems, roots and soils during a growing season (branching, flowering and podding stages) of soybean (Glycine max; a species highly sensitive to O) to background O concentration (44.8 ± 5.

Unlabelled: Changing land use systems impact on local edaphic factors and microbial abundance and diversity, however, the information on it in central Myanmar's soils is still lacking. Therefore, soils with four different land uses were analyzed; WAP (soil from perennial tree orchard), PNON (soil from crop rotation of peanut and onion), SESA (soil from mono-crop of sesame) and CHON (soil from mono-crop of onion for 3 years consecutively). Soil organic carbon (SOC), total nitrogen (TN), dissolved organic carbon (DOC), ammonium nitrogen (NH -N) and pH showed the highest in PNON soil, which suggested crop rotation with high fertilizer input and irrigation had positive effect on the edaphic factors of soil.

Introduction: , a nitrogen-fixing bacterium, was isolated from rhizospheric soil in central Myanmar.

Methods & Materials: The nitrogen-fixing activity of this bacterium was detected by plate screening method using glucose nitrogen free mineral medium and ammonium test-kit Cellulolytic activity was screened by plat assay and detected by Dinitrosalicyclic acid method (DNS).

Results & Discussion: The isolated grew in media containing 3-12% of NaCl, although the growth became poor when NaCl concentrations increased.

The objective of the present study was to observe the changes of β-adrenergic receptor (βAR) protein expression in a canine model of heart failure (HF), and the function of cardiocytes after transfection with Adv-βAR. The canine model of chronic HF was induced by rapid right ventricular pacing and cardiocytes were isolated with collagenase II. Cardiocytes were transfected with Adv-βAR to observe contractile function with a motion edge-detection system of single cells.

CO assimilation by autotrophic microbes is an important process in soil carbon cycling, and our understanding of the community composition of autotrophs in natural soils and their role in carbon sequestration of these soils is still limited. Here, we investigated the autotrophic C incorporation in soils from three natural ecosystems, i.e.

Objective: To identify new tumor specific proteins of renal cell carcinoma (RCC) using proteomic analysis.

Methods: Nine renal cell carcinomas were resected and these surgical operations were carried out from June 2007 to September 2008 in the Urology Department of the Second Affiliated Hospital of Soochow University, Suzhou, Jiangsu Province, China. The cancer tissues and para-cancer normal tissues were preserved in liquid nitrogen.
