Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810041358
Abstract: The structure of the title compound, catena-poly[[[di-μ-aqua-μ-fumarato-μ-(boric acid)-disodium]-di-μ-aqua] boric acid monosolvate], contains two crystallographically independent Na+ cations, each being six-coordinated by one fumarate O atom, one boric acid O atom and four water O atoms in a distorted octahedral geometry. Adjacent [NaO2(OH2)4] units share edges and are linked into chains propagating parallel to [100]. The free boric acid molecules are connected to the chains through strong intermolecular O—H...O hydrogen bonds. Additional O—H...O hydrogen bonds between the water molecules, the free and coordinated boric acid molecules and the fumarate anion lead to the formation of a three-dimensional supramolecular structure. With the exception of the two water molecules, all other atoms lie on mirror planes.

Abstract: Denitrificationis the ability of bacteria to use nitro-gen oxides(NO3-and NO2-)as electron acceptorsto pro-duce gaseous nitrogen,mainly N2.The oxidation of or-ganic material coupled to reduction of oxygen leads to ahigher energy yield than reduction of nitrate.Oxygen iscommonly accepted to be the first choice as electron ac-ceptor1].Therefore,denitrifying is generally thought toonly occur under almost anaerobic conditions.Anefficientwastewater treatment toremove nitrogen components relieson successively ex...

Abstract: The purpose of this study is to promote elementary school student’s conception and interest of insect. In this study, we device a digital game, which possessed scientific and fun, base on the conception of insects (DGBI), then can use it to test elementary school student’s conception about insect.

The DGBI materials creating pattern use as the ADDIE model. First step is to analyze the DGBI materials. We analyze student’s alternative conceptions of insect and what the teaching staff needs to teach in the section of insect, and then we develop three teaching units, namely the ―Bugs Adventure‖, ―Legs and Wings \"and\" Mouthparts and feeding habits‖.

Second, design the DGBI. Making DGBI has a clear teaching aim, multi-learning strategy like conception puzzle, computer simulation and conception mapping etc, an artistic and convenient operating media interface and a learning content that is easy to understand by the words and video in the DGBI materials.

Third, develop the DGBI. Developing DGBI includes making animation component and composing animation component, these animation components makes 94.4% of students prefer to use DGBI materials to learn the conceptions of insect, especially the constructional detail magnify function and interactive game design in the teaching materials increase the student’s learning interest.

Forth, implement DGBI. We invite Two national college professors and four senior science teachers to use DGBI, and then we interview them to collect the testing amendments, and corrected it.Fifth, evaluate DGBI. We use quasi-experiment design and questionnaire survey to evaluate DGBI. In the quasi-experiment design, we select 111 students for four classes in an elementary school in New Taipei City and ask them to use DGBI, and then we tested them by the ―Insects Conceptions test‖. We found that after using the DGBI materials, the student's post-test scores (13.64) is higher than the pre-test scores (7.55), and there are significant differences (t = 16.47,p = .00)and helps the student to establish the correct concept of insect.. In the questionnaire survey, we ask 6 elementary school teachers to write down the ―digital materials quality certification evaluation form‖ after using DGBI. The teachers think that DGBI has an organizational integrity of the insect teaching material. When using DGBI, they can teach the insect unit as a game, and student can learn the insect unit on student's own initiative, which allows students to study the conceptions of insect step-by-step.

Abstract: The PI3K/Akt/mTOR and JAK/STAT3 signaling pathways are important for regulating apoptosis, and are frequently activated in cancers. In this study, we targeted STAT3 and mTOR in human hepatocellular carcinoma Bel-7402 cells and examined the subsequent alterations in cellular apoptosis. The expression of STAT3 was silenced with small interfering RNA (siRNA)-expressing plasmid. The activity of mTOR was inhibited using rapamycin. Following treatment, Annexin V/propidium iodide staining followed by flow cytometry and Hoechst33258 immunofluorescence staining was used to examine cellular apoptosis. JC-1 staining was used to monitor depolarization of mitochondrial membrane (ΔΨm). Furthermore, the expression of activated caspase 3 protein was analyzed by Western blotting. Compared to non-treated or control siRNA-transfected cells, significantly higher levels of apoptosis were detected in siSTAT3-transfected or rapamycin-treated cells (P < 0.05), which was further enhanced in cells targeted for both molecules (P < 0.05). The pro-apoptotic effects were accompanied with concomitant depolarization of mitochondrial membrane and up-regulation of activated caspase 3. Combined treatments using rapamycin and STAT3 gene silencing significantly increases apoptosis in Bel-7402 cells, displaying more dramatic effect than any single treatment. This study provides evidence for targeting multiple molecules in cancer therapy.

Abstract: Aims Our objectives were to reveal changes in plant functional groups and species diversity under three grassland using modes in typical steppe of Inner Mongolia, China. Methods Three plots in similar habitats were selected from the Hulunbeier steppe area of the Hui River National Nature Reserve: an meadow plot (controlled utilization), pasture plot (moderate utilization) and public pasture plot (severe utilization). Plots were 250 m × 250 m and consisted of three sample belts separated by 20 m. Each sample belt had eight 1 m × 1 m sample plots. Important findings There were differences in species composition and community characteristics of the functional groups. Shrubs and sub-shrubs combined were significantly different (p < 0.05) among the plots, with the highest value in meadow. Perennial grasses were significantly different (p < 0.05). Annual and biennial herbs combined had significant differences (p < 0.05), with the highest value in the public pasture. The public pasture also had the highest percentage of the xerophyte functional group (50%) and the lowest mesoxerophyte and mesophyte (19%), and differences were significant (p < 0.05) among the plots. The biomass of shrubs and sub-shrubs were lower in all plots. The combined biomass of perennial grasses and forbs decreased with the increase in grassland use intensity among meadow, pasture and public pasture, while the combined biomass of annual and biennial herbs increased. With the increase in use intensity, the community structure and composition tended to become simplified and susceptible to change. Richness and diversity were lowest in the pasture and highest in meadow. Differences in evenness were not significant. The use of meadow contributed to improving the health of the grassland, but pasture and public pasture exhibited over-grazing phenomena. The public pasture had degraded significantly because of the uncertainty about property responsibility and ineffective management.
