TUNED MECHANICAL PROPERTIES ACHIEVED BY VARYING POLYMER STRUCTURE-KNOWLEDGE THAT GENERATES NEW MATERIALS FOR TISSUE ENGINEERING

引用

Chinese Journal of Polymer Science 2007年第2期25卷 113-118页

作者： anna Finne Wistrand ann-Christine Albertsson Department of Fiber and Polymer Technology Royal Institute of TechnologyStockholmSweden

By changing both the monomer composition and the polymer structure, we have varied the mechanical properties of resorbable polymers. The polymers were synthesized by ring-opening polymerization using L-lactide （LLA）, ε-caprolactone （εCL）, trimethylene carbonate （TMC） and 1,5-dioxepan-2-one （DXO） as monomers. Well-defined triblock copolymers, microblock copolymers and networks have been evaluated, and comparisons between them show that it is possible to tune the mechanical properties. Triblock copolymers with an amorphous middle block of poly（1,5-dioxepan-2- one）（PDXO） and semi-crystalline end-blocks of poly（ε-caprolactone）（PCL） were stronger and had a higher strain at break than triblock copolymers with poly（L-lactide）（PLLA） as end-blocks. Polymers with both DXO and TMC in the amorphous middle-block and PLLA as end-blocks showed a lower stress at break, but the material gained elasticity, a property which is very valuable in tissue engineering. Mechanical properties of networks, synthesized by a novel method, containing PDXO and PCL are also presented. Although it is difficult to compare them with the uncross-linked polymers, this is an additional way to modify and widen the properties.

Transcriptome analysis of sugar beet root maggot （Tetanops myopaeformis） genes modulated by the Beta vulgaris host

引用

Insect Science 2018年第2期25卷 222-234页

作者： Haiyan Li ann C. Smigocki USDA-ARS Molecular Plant Pathology Laboratory Beltsville Maryland US

Sugar beet root maggot （SBRM, Tetanops myopaeformis von R6der） is a major but poorly understood insect pest of sugar beet （Beta vulgaris L.）. The molecular mecha- nisms underlying plant defense responses are well documented, however, little information is available about complementary mechanisms for insect adaptive responses to overcome host resistance. To date, no studies have been published on SBRM gene expression pro- filing. Suppressive subtractive hybridization （SSH） generated more than 300 SBRM ESTs differentially expressed in the interaction of the pest with a moderately resistant （F1016） and a susceptible （F1010） sugar beet line. Blast2GO v. 3.2 search indicated that over 40% of the differentially expressed genes had known functions, primarily driven by fruit fly D. melanogaster genes. Expression patterns of 18 selected EST clones were confirmed by RT-PCR analysis. Gene Ontology （GO） analysis predicted a dominance of metabolic and catalytic genes involved in the interaction of SBRM with its host. SBRM genes function- ing during development, regulation, cellular process, signaling and under stress conditions were annotated. SBRM genes that were common or unique in response to resistant or susceptible interactions with the host were identified and their possible roles in insect responses to the host are discussed.

Q1你的作品非常活泼可爱、童心未泯。能讲讲你的童年生活吗?你小时候是个什么样的孩子,每天都爱做些什么?我像其他所有的孩子一样,充满想象力,而且有使不完的劲儿。不上课的时候我会花大量时间呆在户外。骑单车是我最喜欢的运动,因为我很享受独自起程并且放肆想象的过程。直到现在,我走路时都仍旧习惯去幻想。我认为艺术家们都始终保持着儿时想象的能力,这也是艺术家区别于普通人的重要一点。

The effects of temperature and resource availability on denitrification and relative N_(2)O production in boreal lake sediments

引用

Journal of Environmental Sciences 2016年第9期28卷 82-90页

作者： Maria Myrstener Anders Jonsson ann-Kristin Bergstrom Department of Ecology and Environmental Science Umea University90187 UmeaSweden

Anthropogenic environmental stressors（like atmospheric deposition,land use change,and climate warming） are predicted to increase inorganic nitrogen and organic carbon loading to northern boreal lakes,with potential consequences for denitrification in ***,our ability to predict effects of these changes is currently limited as northern boreal lakes have been largely neglected in denitrification *** aim of this study was therefore to assess how maximum potential denitrification and N_2O production rates,and the relationship between the two（relative N_2O production）,is controlled by availability of nitrate（NO_3^-）,carbon（C）,phosphorus（P）,and *** were performed using the acetylene inhibition technique on sediments from a small,nutrient poor boreal lake in northern Sweden in *** potential denitrification and N_2O production rates at 4°C were reached already at NO_3^-additions of 106–120 μg NO_3^-–N/L,and remained unchanged with higher NO_3 *** incubation temperatures increased maximum potential denitrification and N_2O production rates,and Q10 was somewhat higher for N_2O production（1.77） than for denitrification（1.69）.The relative N_2O production ranged between 13% and 64%,and was not related to NO_3^-concentration,but the ratio increased when incubations were amended with C and P（from a median of 16% to 27%）.Combined,our results suggests that unproductive northern boreal lakes currently have low potential for denitrification but are susceptible to small changes in NO_3 loading especially if these are accompanied by enhanced C and P availability,likely promoting higher N_2O production relative to N_2.
