[Response of Nitrification Potential and Ammonia Oxidation Microbial Community in Purple Soils to the Application of Biochar Combined with Chemical Fertilizer and Manure].

The effects of manure and chemical fertilizer combined with biochar on nitrification potential and ammonia oxidation microbial change characteristics of purple soils were studied to explore the effects of fertilization measures and soil environmental factors on nitrification potential and ammonia oxidation microbial change characteristics. In this study, purple soil was taken as the research object, and five treatments were set up:no fertilizer(CK), chemical fertilizer(F), manure(P), chemical fertilizer plus biochar(FP), and manure plus biochar(PP). PCR and T-RFLP methods were used to study the characteristics of soil AOA and AOB communities, and soil nitrification potential and environmental factors were measured at the same time to determine the effect of manure combined with biochar on the nitrification potential of purple soil.

[Effect of Adding Granular Activated Carbon (GAC)/Manganese Dioxide (MnO) for the Anaerobic Digestion of Waste Activated Sludge].

The addition of conductive materials or metal oxide nanoparticles to an anaerobic system is an attractive strategy to enhance anaerobic digestion. The effect of granular activated carbon (GAC) and/or manganese dioxide (MnO) on waste activated sludge (WAS) anaerobic digestion was investigated by batch experiments. The experiments were provided in control, GAC, MnO, and GAC/MnO groups, which were named R0, R1, R2, and R3, respectively.

sp. nov., isolated from biological soil crusts.

A pink-pigmented, Gram-negative, rod-shaped, obligate aerobic bacterial strain, MIMD6, was isolated from biological soil crusts in PR China. Cells grew at 20-37 °C (optimum, 30 °C), at pH 6-8 (optimum, pH 7) and with 0-1 % (w/v) NaCl (optimum, 0 %). Strain MIMD6 could use methanol or formate as a sole carbon source to grow, and carried methanol dehydrogenase genes and , supporting its methylotrophic metabolism.

The efficacy of postoperative radiotherapy in localized primary soft tissue sarcoma treated with conservative surgery.

Background: To evaluate the efficacy of postoperative radiotherapy (RT) on local failure-free survival (LFFS), distant metastasis-free survival (DMFS) and overall survival (OS) in patients with localized primary soft tissue sarcoma (STS) and to identify prognostic factors.

Methods And Materials: Between January 2000 and July 2010, 220 consecutive patients with localized primary STS, who received conservative surgery with or without postoperative RT, were enrolled in the study. Survival curves were constructed by the Kaplan-Meier method and log-rank test was used to assess statistical significance.

Avian leukosis virus subgroup J triggers caspase-1-mediated inflammatory response in chick livers.

Many pathogens trigger caspase-1-mediated innate immune responses. Avian leukosis virus subgroup J (ALV-J) causes serious immunosuppression and diverse tumors in chicks. The caspase-1 inflammasome mechanism of response to ALV-J invading remains unclear.

Effect of human interferon-λ1 recombinant adenovirus on a gastric cancer orthotopic transplantation model.

The aim of the present study was to investigate the effect of human interferon-λ1 recombinant adenovirus (r-Ad-hIFN-λ1) on gastric carcinoma. Human SGC-7901 cells were utilized to create an orthotopic implantation model of gastric cancer in nude mice through sterile surgery. The mice were randomly divided into three groups: Phosphate-buffered saline control (blank), adenovirus encoding bacterial β-galactosidase (Ad-Lac Z) empty vector and r-Ad-hIFN-λ1.

[Comparative study on effects of different acupuncture manipulation methods at neiguan (PC 6) on hand spasm in the patient of stroke].

Objective: To observe therapeutic effects of different needling methods at Neiguan (PC 6) on hand spasm in the patient of stroke.

Methods: One hundred and seventy-two cases were randomly divided into a simple acupuncture group (n=36), a slowly twirling needle group (n = 34), a rapidly twirling needle group (n = 30), a simple lifting-thrusting group (n = 35) and a lifting-thrusting-twirling needle group (n = 37). Acupuncture was given at Neiguan (PC 6), twice each day, 5 min each time, and in combination with rehabilitation exercise.
