| 1 | Exploring polyamines:Functions in embryo/fetal development显示文摘Polyamines such as putrescine, spermidine, spermine and agmatine are aliphatic polycationic compounds present in all living cells, and are derived from amino acids, intestinal bacteria, exfoliated enterocytes and supported from diet. Polyamines as the key compounds play essential role in cell proliferation, growth and differentiation. They also exert significant effects on embryonic development,implantation, embryonic diapause, placentation, angiogensis and fetal development. This review paper summarizes the functions of polyamines and embryo/fetus development and its regulatory mechanism which should help to provide some evidences for clinic. | Tarique Hussain Bi'e Tan Wenkai Ren Najma Rahu Dildar Hussain Kalhoro Yulong Yin | 2017 | Animal Nutrition2017，，1： | 6 |
| 2 | Spectroscopic studies of dye-surfactant interactions with the co-existence of heavy metal ions for foam fractionation显示文摘The interaction between a cationic dye Methylene Blue(MB) and an anionic surfactant sodium dodecyl sulfate(SDS) with the presence of Cd2+ was investigated spectrophotometrically in a certain concentration range.The spectrophotometric measurements of dye-metal ion-surfactant system were carried out.The results indicated that the SDS concentration had a significant influence on the dye spectrum,while the addition of Cd2+ hardly caused change of the maximum value of absorbance.According to this observation,we concluded that electrostatic and hydrophobic interaction between dye and surfactant occurred up to a certain level,and the homo-ions Cd2+ almost exerted no effect on the dye-surfactant complexation,establishing a theoretical foundation for simultaneous removal of organic dye and heavy metal using foam fractionation.Meanwhile,the effects of their interaction on foam performance were investigated.The results showed that the addition of Cd2+ favored the tendency to ameliorate foam properties just contrary to MB.The feasibility of foam separation for dye and heavy metal removal from simulated wastewater was also confirmed using a continuous foam fractionator.In the simultaneous removal process,with the initial SDS concentration ranging from 0.5 to 5.0mmol/L,the maximum removal efficiencies of MB and Cd2+ were obtained as 99.69% and 99.61%,respectively.The enrichment ratios were reduced from24.34 to 7.65 for MB and from22.01 to 3.35 for Cd2+. | Dongmei Zhang Guangming Zeng Jinhui Huang Wenkai Bi Gengxin Xie | 2012 | Journal of Environmental Sciences2012，24，12： | 2 |
