| 1 | Nitrogen Release from Slow-Release Fertilizers in Soils with Different Microbial Activities显示文摘Soil microbial activity is recognized as an important factor affecting nitrogen (N) release from slow-release fertilizers. However,studies on the effect of size and activity of soil microflora on fertilizer degradation have provided contrasting results. To date, no clear relationships exist between soil microbial activity and the release of N from slow-release fertilizers. Hence, the aim of this study was to better understand such relationships by determining the release of N from three slow-release fertilizers in soils with different microbial activities. Soils were amended with urea-formaldehyde (UF), isobutylidene diurea (IBDU), and crotonylidene diurea (CDU). Urea, a soluble fertilizer, was used as the control. Fertilized soil samples were placed in a leaching system, and the release of N was determined by measuring ammonium-N and nitrate-N concentrations in leachates during 90 d of incubation. Non-linear regression was used to fit N leaching rate to a first-order model. In all the treated soils, N was released in the order: urea (89%–100%) > IBDU (59%–94%) >UF (46%–73%) > CDU (44%–56%). At the end of incubation, N released from CDU did not differ (P > 0.05) among soils. On the contrary, UF and IBDU released significantly lower (P < 0.05) amounts of N in the soil with higher microbial activity and lower pH.The rate constant (K_0) for UF was lower (P < 0.05) in the soil with lower pH. Taken together, our results indicated that soil microbial size and microbial activity had a marginal effect on fertilizer mineralization. | Pierfrancesco NARDI Ulderico NERI Giovanni DI MATTEO Alessandra TRINCHERA Rosario NAPOLI Roberta FARINA Guntur V.

| 2 | Standardized bioactive fraction of Phaleria macrocarpa(Proliverenol) prevents ethanol-induced hepatotoxicity via down-regulation of NF-kB-TNFα-caspase-8 pathway显示文摘Objective: To verify that Proliverenol has a potential ability in protecting cells from ethanol-induced hepatotoxicity.Methods: Activity of Proliverenol against ethanol-induced apoptosis was evaluated at m RNA and protein levels in Hep G2 cell exposed to Proliverenol for 1 and 3 h.Results: Proliverenol conferred hepatoprotective activity through increasing cell survival up to 53%–69% via up-regulation of APEX1 DNA repair enzyme for 3.0–4.7 fold and down-regulating of nuclear factor-kB, tumor necrosis factora and caspase-8 expression,allowing them to prevent 4.5–6.9 fold of alanine aminotransferase(ALT) leakage in Hep G2 cells. Our finding revealed that Proliverenol repressed expression of ALT, which is significantly important as possible alternative mechanism for increased blood transaminase activities. In addition, the result also showed that caspase-8 pathway seemed to be involved in the molecular pathway rather than directly inducing mitochondrial damage.Conclusions: The data support our hypothesis that Proliverenol has a potential ability in protecting cells from ethanol-induced hepatotoxicity. We propose that Proliverenol provides hepatoprotective activity through up-regulating expression of APEX1 that repress DNA fragmentation, and down-regulating expression of nuclear factor-kB, tumor necrosis factora and caspase-8, which therefore repress ALT leakage and its expression. | Guntur Berlian Olivia Mayasari Tandrasasmita Raymond Rubianto Tjandrawinata | 2016 | Asian Pacific Journal of Tropical Biomedicine2016，6，8： | 2 |
