Effect of Inoculation with Arbuscular Mycorrhizal Fungus on Nitrogen and Phosphorus Utilization in Upland Rice-Mungbean Intercropping System

引用

Agricultural Sciences in China 2010年第4期9卷 528-535页

作者： XIAO Tong-jian YANG qing-song ran Wei XU Guo-hua SHEN Qi-rong Department of Plant Nutrition College of Resoures and Environmental Sciences Nanjing Agricultural University Nanjing 210095 P.R.China

The effect of arbuscular mycorrhiza fungi （AMF） on plant growth and nutrition utilization in upland rice and mungbean intercropping system was studied. A pot experiment was conducted in the greenhouse and AMF colonization rates of rice and mungbean roots, plant nutrient contents, the ability of nitrogen fixation, and nutrient contents changed in the soil were analyzed. The results were obtained as follows： the rates of AMF colonization of rice and mungbean roots were reached to 14.47 and 92.2% in intercopping system, and increased by 4.11 and 11.95% compared with that of in monocropping; the nirtrogen contents of mungbean and rice were increased by 83.72 and 64.83% in shoots, and 53.76 and 41.29% in roots, respectively, while the contents of iron in shoot and root of mungbean were increased by 223.08 and 60.19%, respectively. In the intercropping system with inoculation of AMF, the biomass of mungbean increased by 288.8%. However, the biomass of rice was not significantly changed among all treatments with or without inoculation of AMF recorded. The number and dry weight of nodules were significantly increased either when mungbean was intercropped with rice or inoculated with AMF. When compared with that of monocropping without AMF inoculation, the contents of nitrogen, phosphorus and iron in nodules of intercropping mungbean with inoculation increased by 80.14, 69.54 and 39.62%, respectively. Additionally, intercropping with AMF inoculation significantly increased soil nitrogen content, but reduced soil phosphorus content. We concluded that upland rice-mungbean intercropping system and inoculation with AMF improved the nutrient uptake, the ability of nitrogen fixation and the growth of mungbean.

Quantitative and Qualitative Body Traits of Longling Yellow Goats in China

引用

Agricultural Sciences in China 2010年第3期9卷 408-415页

作者： LENG Jing ZHU Ren-jun ZHAO Guo-rong YANG qing-ran MAO Hua-ming Yunnan Provincial Key Laboratory of Animal and Feed Science Yunnan Agricultural University Kunming 650201 P.R.China Faculty of Food Science and Technology Yunnan Agricultural University Kunming 650201 P.R.China Animal Husbandry Bureau of Longling County Longling 678300 P.R.China

Quantitative, qualitative and phenotypic body measurements were determined on Longling Yellow goats in Longling of Yunnan Province in China. Body weight was determined at birth and then at 3, 6, 9, 12, 18, 24, 36, and 48 mon of age. Body measurements traits including height at wither （HW）, body length （BL）, heart girth （HG）, chest depth （CD）, and circumference of cannon bone （CCB） were determined at 3, 6, 9, 12, 18, 24, 36, and 48 mon of age. Phenotypic traits including coat colour, horns type, tip horn torsion, nose type, hair on forehead, wattles, ear lobes, black back line, hair on legs, and black hair on belly were determined at 12, 18, 24, 36, and 48 mon of age. Males were heavier （P〈0.01 or P〈0.05） than females; and except for chest depth at 24 mon of age （P 〉 0.05）, all other body measurements were also higher （P 〈 0.01 or P 〈 0.05） in males. HW, BL, CD, HG, and BW increased （P 〈 0.01） with age, except for 48 mon of females （P 〉 0.05）; while CCB did not always increase with age. HG had the highest correlation （P〈0.01） with body weights of both sexes. No differences were observed between the two sexes in the colour of the coat, horn type, tip horn torsion, nose type, ear lobes, black back line, and black hair on belly. However, differences exist between the two sexes in the presence of hair on forehead, wattles and long hair on legs. The female goats absence of tip horn torsion had positive effect on all variables measured at 36 and 48 mort of age （P〈0.01 or P〈0.05）. The presence of wattles was associated with heavier body weights from 18 mort （P〈0.01） of age onward, and also with longer HW, BL and CD （P〈0.01 or P〈0.05） in female goats. Female goats with ear lobes had heavier body weights at 12, 36 and 48 mon （P〈0.01） and longer CCB at 12 and 24 mon of ages （P〈0.05）. Hair on legs and black hair on belly only had partly effect body measurements on 12 mon of Longling Yellow female goats. Results of this study provide valuable information that will assist breeder

NAMPT inhibition synergizes with NQO1-targeting agents in inducing apoptotic cell death in non-small cell lung cancer cells

引用

Chinese Journal of Natural Medicines 2016年第8期14卷 582-589页

作者： LIU Hui-Ying LI qing-ran CHENG Xue-Fang WANG Guang-Ji HAO Hai-Ping State Key Laboratory of Natural Medicines Key Lab of Drug Metabolism and Pharmacokinetics China Pharmaceutical University Department of Physiology and Pathophysiology School of Basic Medical Sciences Peking University

Nicotinamide phosphoribosyltransferase(NAMPT) catalyzes the first rate-limiting step in converting nicotinamide to NAD^+, essential for a number of enzymes and regulatory proteins involved in a variety of cellular processes, including deacetylation enzyme SIRT1 which modulates several tumor suppressors such as p53 and FOXO. Herein we report that NQO1 substrates Tanshione IIA(TSA) and β-lapachone(β-lap) induced a rapid depletion of NAD^+ pool but adaptively a significant upregulation of NAMPT. NAMPT inhibition by FK866 at a nontoxic dose significantly enhanced NQO1-targeting agent-induced apoptotic cell death. Compared with TSA or β-lap treatment alone, co-treatment with FK866 induced a more dramatic depletion of NAD^+, repression of SIRT1 activity, and thereby the increased accumulation of acetylated FOXO1 and the activation of apoptotic pathway. In conclusion, the results from the present study support that NAMPT inhibition can synergize with NQO1 activation to induce apoptotic cell death, thereby providing a new rationale for the development of combinative therapeutic drugs in combating non-small lung cancer.

A New Series of Mo-free 21.5Cr-3.5Ni-xW-0.2N Economical Duplex Stainless Steels

引用

Journal of Iron and Steel Research International 2014年第1期21卷 69-75页

作者： Zi-xing ZHANG qing-xuan ran Yu-lai XU Xiao-jiang YU Da-wei JIANG Xue-shan XIAO Laboratory for Microstructures Institute of MaterialsShanghai University

A new series of economical Mo-free duplex stainless steels 21.5Cr-3.5Ni-xW-0. 2N （x = 1.8 -- 3. 0, mass%） have been developed. The effects of W on mechanical properties and corrosion resistance were investigated, and the microstructures were analyzed by optical microscopy, X-ray diffraction, transmission electron microscopy and electron backscatter diffraction. The designed steels have a balanced ferrite-austenite relation and are free of sigma phase after solution treatment at 750--1 300 ~C for 30 min followed by water-quenching, whereas a small number of Cr23 C~ precipitates were found after solution treatment at 750 ~C. After solution treatment at 1050 ℃, the steel with 1.8~ （mass percent） W exhibits the highest room temperature tensile strength due to the strongest work hardening effect, while the steel with 3.0% （mass percent） W exhibits the highest fracture elongation owing to the transformation-in- duced plasticity （TRIP） effect. The ductile-brittle transition （DBT） and martensite transformation are respectively found in the ferrite and austenite, which deteriorates the impact properties of the steels with the increase of W con- tent. The corrosion resistance of the designed steels is improved with the increase of W content. The pitting resistance of austenite is obviously better than that of ferrite for the designed alloys. Among the designed steels, the steel with 1.8% （mass percent） W is found to be an optimum steel with excellent comprehensive properties and lowest production cost.
