摘要：
Objective: To investigate the theoretical model of the three-dimensional structure of mosquitocidal Cry30Ca2 and its molecular docking with N-acetylgalactosamine. Methods: The theoretical model of Cry30Ca2 was predicted by homology modeling on the structure of the Cry4Ba. Docking studies were performed to investigate the interaction of Cry30Ca2 with N-acetylgalactosamine on the putative receptor. Results: Cry30Ca2 toxin is a rather compact molecule composed of three distinct domains and has approximate overall dimensions of 95 by 75 by 60Å. Domain II is a helix bundle, Domain II consists of three antiparallel β-sheets, Domain III is composed of two β-sheets that adopt a β-sandwich fold. Residue 321Ile in loop1, residues 342Gln 343Thr and 345Gln in loop2, residue 393Tyr in loop3 of Cry30Ca2 are responsible for the interactions with GalNAc via 7 hydrogen bonds, 6 of them were related to the oxygen atoms of hydroxyls of the ligand, and one to the nitrogen of the ligand. Conclusion: The 3D structure of Cry30Ca2 resembles the previously reported Cry toxin structures but shows still some distinctions. Several residues in the loops of the apex of domain II are responsible for the interactions with N-acetylgalactosamine. © 2012 The Editorial Board of Biomedical and Environmental Sciences.

摘要：
The objective of this work was to study the comparison of the adsorption performances of phenol in aqueous solution onto H103 resin and XAD-4 resin. Experimental results showed that the molecular form of phenol is favorable for the adsorption. The adsorption capacity of phenol onto H103 was much larger than that of XAD-4 due to its average pore diameter. The pseudo-first-order rate equation can characterize the adsorption of phenol onto H103 and XAD-4. The rate constant k<inf>1</inf> for XAD-4 is greater than the one of H103 at the same condition, consistent with the shorter required time for XAD-4. ©(2012) Trans Tech Publications, Switzerland.

摘要：
A novel hyper-cross-linked polymeric adsorbent modified with acetylaniline as the cross-linked bridge (denoted GQ-02) was synthesized for the enhanced removal of bisphenol A (BPA) from aqueous solution. Its chemical structure and pore structure were characterized by infrared spectroscopy and surface area analysis. Results showed that the adsorption capacity of BPA onto GQ-02 was larger than that of the commercial resins NDA-150, H103, NDA-88, NDA-99, and XAD-4 due to the cross-linked bridge of acetylaniline uploaded on GQ-02 resin. The solution pH had no significant effect on the adsorption capacity until it was higher than 6.39. The adsorption rate of GQ-02 was greater than that of H103 because of the longer cross-linked bridge between two benzene rings. The adsorption isotherms could be correlated to the Langmuir equation. More favorable adsorption of BPA onto GQ-02 than H103 was further demonstrated by thermodynamic analysis. Nearly 100% regeneration efficiency for GQ-02 was achieved by 80% ethanol and 0.5. mol/L NaOH. © 2012.

摘要：
A series of novel bis-Schiff base were synthesized from 1-aryl-3-methyl-4-benzoyl-5-pyrazolones and diethylenetriamine (or triethylenetetramine) as the starting materials. All of these bis-Schiff bases were characterized by means of NMR, IR, and MS. The UV-vis absorption spectra and fluorescent spectra of these bis-Schiff bases were also measured. Moreover, the B3LYP/6-31G(d) method was used to optimize the ground state geometry of the bis-Schiff bases; and the UV-vis spectroscopic properties of the products were computed and compared with corresponding experimental data based on cc-pVDZ basis set of TD-B3LYP method. It has been found that all of these bis-Schiff bases show a remarkable absorption peak in a wavelength range of 270-340 nm; and their maximum emission peaks are around 348 nm.

摘要：
The 20 kb DNAs are associated with crystals in many subspecies of Bacillus thuringiensis. We isolated 20 kb DNAs from crystals of B. thuringiensis strain 4.0718, then constructed a gene library using DNA fragments of Sau3AI partial digestion and pbluescriptIISK(+) vector. We screened out 440 recombinants, yielding a genomic coverage of ten and including 99% sequence of DNA which achieved the required theoretical value to construct the gene library. Through NCBI Blast and homology analysis, the sequencing results proved that the DNA came from the chromosome of B. thuringiensis. Moreover, we have completed the multiple alignment of homologous ropB protein sequences and phylogenetic analysis using bioinformatic software. For further investigation of the interactions between 20 kb DNAs and protoxins, molecular docking has also been done.

摘要：
A new effective fluorescent sensor based on rhodamine was synthesized, which was induced by Cu<sup>2</sup> in aqueous media to produce turn-on fluorescence. The new sensor 1 exhibited good selectivity for Cu<sup>2</sup> over other heavy and transition metal (HTM) ions in H<inf>2</inf>O/CH <inf>3</inf>CN(7:3, v/v). Upon addition of Cu<sup>2</sup>, a remarkable color change from colorless to pink was easily observed by the naked eye, and the dramatic fluorescence turn-on was corroborated. Furthermore, kinetic assay indicates that sensor 1 could be used for real-time tracking of Cu<sup>2</sup> in cells and organisms. In addition, the turn-on fluorescent change upon the addition of Cu<sup>2</sup> was also applied in bioimaging. ©2012 Elsevier B.V. All rights reserved.

摘要：
A novel water-compatible microporous and mesoporous hyper-cross-linked resin modified with phenolic hydroxyl group (named as GQ-03) was synthesized to remove aniline in aqueous solution as compared with XAD-4. The maximum adsorption capacity of GQ-03 emerged at the molecular state for both aniline and p-cresol while the pH dependency trend of aniline adsorbed onto XAD-4 was accordant with the dissociation curve of aniline. The ionic strength influenced the adsorption obviously. The pseudo-first-order rate equation could describe the adsorption process of aniline onto GQ-03 in two stages while this equation could characterize the entire adsorption process of XAD-4. The adsorption isotherms could be correlated to the Freundlich model, higher K F and n values for GQ-03 than XAD-4. The breakthrough capacity and the total adsorption capacity of GQ-03 and XAD-4 was up to 47.2 mg mL -1 and 28.3 mg mL -1 , 271.7 mg mL -1 and 115.6 mg mL -1 , respectively. The size matching between the pore diameter of GQ-03 and the molecular size of aniline, and hydrogen bonding between GQ-03 and aniline resulted in the larger adsorption capacity. © 2012 Elsevier B.V.

摘要：
以洞庭湖湿地新发现的Cd高富集植物——蒌蒿(Artemisia selengensis)为试验材料,采用盆栽方式,系统研究了蒌蒿在生长期内对Cd的性状反应及富集特征.结果表明,大于40mg.kg~(-1)的Cd胁迫对蒌蒿叶片伤害明显,且导致生物量下降,但植株在100mg.kg~(-1)胁迫下可完成生活史,对Cd有较强的耐受能力;土壤中有效态Cd的含量仅占土壤全Cd含量的15.3%~37.1%;相同胁迫浓度下,各生长阶段的植株体内Cd含量差别不大,但由于生物量的原因,幼苗期对Cd的提取量显著小于其他时期,其中40~60mg.kg~(-1)的Cd处理可使蒌蒿地上部分Cd含量达492~588mg.kg~(-1)(成株期),且植株对该浓度范围的Cd污染去除效果最好;蒌蒿可作为对湿地土壤Cd污染较理想的修复植物加以研究和利用.

The co-doped TiO<inf>2</inf> nanoparticles were characterized by X-ray diffraction and transmission electro microscopy. The photodegradation of glyphosate has been investigated in aqueous suspensions of doped TiO<inf>2</inf> under visible irradiation. The results exhibit a higher thermal stability of anatase than pure TiO<inf>2</inf>. The uniform test results show the optimal conditions: n<inf>Ce</inf>/n<inf>Ti</inf> n<inf>N</inf>/n<inf>Ti</inf> and calcining temperature was 0.08, 0.01 and 800°C. The highest degradation rate for co-doped TiO<inf>2</inf> show five times photocatalytic activity of Degussa P25. ©(2012) Trans Tech Publications.

摘要：
Industrial waste water with high levels of lead has serious threat to human health and other organisms. Power generation methods were used for recycling of lead. Some factors such as temperature, power generation time, the anode material, type and concentration of anode area solution on the power generation process were studied to find the optimal process parameters. The experimental results show that: in the optimum conditions, the recovery rate of lead was more than 90% and the lead concentration in waste water has reached the discharge standard. This method does not produce by-products of environmental pollution in the power generation process and needn't external supply of energy but produce certain energy. So it is a green chemistry technology. ©(2012) Trans Tech Publications.

摘要：
A novel p-acetaminophen resin (named as GQ-1) was synthesized with chloromethylated polystyrene and p-acetaminophen. It can be used without any wetting process. The objective of this work was to study the adsorption performances for vanillin onto GQ-1 with two kinds of the hydrogen bond site of acetamino group and hydroxyl group. The results showed that the adsorption property of vanillin onto GQ-1 was superior to XAD-4, H103, NDA150, and NDA88. The adsorption capacity of vanillin onto GQ-1 is not greatly discrepant until the solution pH is higher than 5.31. The saturated adsorption quantity of vanillin was up to 141.32 mg/mL (wet resin) according to the dynamic adsorption and desorption experiments at 293 K. The resin could be regenerated by 7 BV ethanol. © 2011 Gu Qing Xiao.
