ZnO nano-particles were synthesized via an ammonical ammonium carbonate solution by precipitation method in presence of some additives such as urea, oleic and stearic acid. The morphology and crystallinity of the obtained zinc oxide particles depend critically on the type of additive which was used. Additives also affected the crystal orientation of precipitate nano-particles. SEM, XRD, BET and UV-visible were used to characterize morphology, microstructure, specific surface area and optical properties of the ***-catalysis properties of the as-prepared ZnO powders were evaluated by degradation of methyl red(acid red) in aqueous solution exposed to UV-light. Results suggested a close relationship among the morphology,size and surface area on photo-catalysis and optical properties of the particles. The widest Egvalue(3.56 e V),highest degradation and decolorization efficiency(99%) were obtained from a sample with the smallest grain size(largest surface area) which were used urea as an additive.

Heavy metals, such as Cu（Ⅱ） and Cd（Ⅱ） are among the hazardous pollutants that lead to severe ecological problems and have a toxic effect on living organisms. This study was carried out on adsorption of Cu（Ⅱ） and Cd（Ⅱ） from single-and multi-component aqueous solutions with Iranian scoria. Two- and three-parameter isotherm models, such as Langmuir, Freundlich, Temkin, Dubinin-Radushkevich, Khan and Toth have been studied for single and bi- nary adsorption of Cu（Ⅱ） and Cd（Ⅱ） onto scoria. The best result was attained from Langmuir model for Cu（Ⅱ） and Cd（Ⅱ） ions in single and binary solution. Therefore, homogenous adsorption is dominated, which was emphasized by three-parameter isotherm models. Based on the value of the free energy of adsorption for Cu（Ⅱ） and Cd（Ⅱ）, the inte-raction between these ions and scoria is a physical adsorption. In order to investigate competitive adsorption behavior, modified and extended Langmuir and Freundlich models have been studied, which indicated that adsorption of Cu（Ⅱ） and Cd（Ⅱ） on scoria has synergistic behavior. Extended Freundlich model and modified Langmuir model described Cu（Ⅱ） and Cd（Ⅱ） adsorption onto scoria, respectively.

The human leucocyte antigen （HLA） complex on chromosome 6p21.3 is the most extensively studied genetic region in Inflammatory bowel disease （IBD）. Consistent evidence of linkage to IBD3 （6p21.1-23）, an area which encompasses the HLA complex, has been demonstrated for both Crohn＇s disease and ulcerative colitis, and a number of replicated associations with disease susceptibility and phenotype have recently emerged. However, despite these efforts the HLA susceptibility gene （s） for IBD remain elusive, a consequence of strong linkage disequilibrium, extensive polymorphism and high gene density across this region. This article reviews current knowledge of the role of HLA complex genes in IBD susceptibility and phenotype, and discusses the factors currently limiting the translation of this knowledge to clinical practice.

We collected acorns from selected Quercus robur and Quercus petraea mother trees growing at sta- tions with different depths to the water table. We produced pairs of micro-cuttings from these single acorns. The obtained pairs of cuttings represented phenotypes of high similarity according to photosynthetic parameters. These pairs of cuttings were used to test the plasticity of response to contrasting water regimes. For each pair, one cutting was submitted to drought and the other was submitted to waterlogging. Drought response was recorded according to gas exchange traits （stomatal closure and water use effi- ciency）. The response to waterlogging was recorded according to the capacity to form hypertrophied lenticels and to maintain the CO2 assimilation rate. Intermediary phenotypes presenting both high water use efficiency and the capacity to develop hypertrophied lenticels were expected.
