标题:通过迈克尔加成聚合反应改善血清耐受性的低分子量pei基聚阳离子基因载体
摘要:通过迈克尔加成反应,从低分子量pei合成一系列聚阳离子基因传递载体,并将化合物与各种杂原子组成连接.琼脂糖凝胶电泳结果表明,这些聚合物可以很好地凝聚质粒dna,并可以保护dna不受核酸酶降解.所形成的对血清稳定的多链体具有均匀的球形纳米颗粒,其适当大小约为200-350 Nm,ζ电位约为+40 Mv.体外实验表明,与25 Kda Pei相比,这些聚合物具有更低的细胞毒性和更高的转染效率.此外,标题材料表现出优异的血清耐受性.在存在10%血清的情况下,获得的转染效率是pei的19倍,即使血清浓度增加到40%以上,也没有观测到te的明显降低.流式细胞术和共聚焦显微镜研究也证明了该材料具有非常好的血清耐受性.

标 题 :Sorbents and method for synthesis of sorbents intended for removal of radionuclides and toxic trace elements from water
发明人：KLAVINS MARIS; ABRAMENKOVS ANDRIS; ANSONE LINDA
权利人:UNIV LATVIJAS
摘要:The invention relates to synthesis of sorbents for removal of radionuclides and toxic trace elements (e.g. heavy metals, no-metallic elements and metalloids) from waters. The offered method for synthesis of sorbents provides covering natural biomaterial structure acting as sorbent matrix with a layer of synthetic polymer containing functional groups by graft polymerization. The sorbent matrix is derived from peat, sawdust or straw.

标题:Ring-expansion of cyclic olefins metathesis reactions with an acyclic diene

权利人:CALIFORNIA INST OF TECHN
摘要:This invention relates generally to synthetic procedures that include the step of ring-opening metathesis of cyclic olefins and reaction with an acyclic diene co-reactant to produce olefin macrocycles by ring expansion, or alternatively. The ring expansion of the cyclic olefin is provided by three types of sequential olefin metathesis (ring-opening, cross, and ring-closing olefin metathesis). More particularly, the invention pertains to synthesis of olefin macrocycles via olefin metathesis reactions using a Group 8 transition metal complex as the metathesis catalyst. Macrocycles provided herein have a variety of uses in the pharmaceutical, biomedical, organic synthesis and chemical industries, such as the production of crown ethers that are useful as metal complexing species.

标 题 :Nanoliter-scale synthesis of arrayed biomaterials and screening thereof
发明人：ANDERSON DANIEL G; LEVENBERG SHULAMIT; LANGER ROBERT S
摘要:A method of screening cell-polymer interactions. The method includes depositing monomers as a plurality of discrete elements on a substrate, causing the deposited monomers to polymerize, thereby creating an array of discrete polymer elements on the substrate, incubating the substrate in a cell-containing culture medium, and characterizing a predetermined cell behavior on each polymer element.

标 题:Removal of acrylonitrile from latex with saturated heterocyclic amines
发明人：SENYEK MICHAEL L
权利人:GOODYEAR TIRE & RUBBER
摘要:Acrylonitrile is a monomer that is widely used in the synthesis of a vast variety of polymers. Undesirable quantities of unpolymerized residual acrylonitrile are often present in these acrylonitrile polymers. This residual or free acrylonitrile dissolved in an acrylonitrile polymer and/or its emulsifier system and the water phase used in its polymerization can be reduced significantly in concentration by treatment with saturated 6 to 7 membered ring heterocyclic amines. These amines react with acrylonitrile by a nitrogen-cyanoethylation reaction which results in the formation of a tertiary amino linkage.

标题 :Synthesis of Degradable Polymers Downhole for Oilfield Applications
发明人：KHLESTKIN VADIM KAMIL EVICH
权利人:KHLESTKIN VADIM KAMIL EVICH
摘要:A method is given for polymerizing monomers downhole to create well treatment polymers. The monomers each contain two polymerizable groups and a degradable group or groups which allow the polymer to degrade under downhole conditions, for example by hydrolysis. Polymerization downhole allows easier, more precise, placement of polymer. Polymer obtained from monomers pumped downhole may be used, for example, for fluid diversion plugs, isolation plugs, formation consolidation, flowback control, and fluid loss control. Synthesized polymer may form gels, films, solids or other structure in treated wellbores, fractures, and/or formations. After the desired effect is achieved, the deposited polymer degrades and the polymer degradation products dissolve, leaving the wellbore, fracture and/or formation clean, with no damage that might have decreased fluid flow.
