In situ formation and the performance of ionically crosslinked thermosensitive chitosan-based hydrogels are presented. Experimental analyses, together with mechanistic descriptions of the events during hydrolysis, are employed to uncover the role of urea and isobutanol as chemical modifiers by comparing ...
J., Kim, S. J. & Martinson, H. G. The poly(A) signal, without the assistance of any downstream element, directs RNA polymerase II to pause in vivo and then to release stochastically from the template. J. Biol. Chem. 277, 42899–42911 (2002). Article CAS PubMed Google Scholar ...
In the series tri-methylvinylsilane, dimethyldivinylsilane, methyltrivinylsilane, and tetravinylsilane, trimethylvinylsilane was shifted bathochromically from the rest of the vinylsilanes, which were grouped together. Allyldimethylvinylsilane showed two independent absorptions.doi:10.1080/10601326908051916...
In contrast, the continuity of the array of excitonically coupled BChls is interrupted at the monomer–monomer interface in the Class-2 dimer, resulting in a ~23-Å gap between adjacent BChls from the two monomers (Figs. S10, S11). Location of PufX and its interactions within the RC–...
Coronal mass ejections (CMEs) are the largest-scale eruptive phenomenon in the solar system, expanding from active region-sized nonpotential magnetic struc
Besides visual observations of behaviour of malefemale encounters at the reproductive sites, we analysed their flight cinematographically by measuring velocity, wing beat frequency, phase relationships of fore- and hind wings, and described the flight paths of different flight manoeuvres. Wing clapping ...
Carried out experiments showed important benefits in terms of reduction in the number of generic rules extracted. We present also a new framework for generating and vi- sually exploring the minimal generic basis MGB. 展开 收藏 引用 批量引用 报错 分享 ...
(mean depth = 13.92X, see Methods). We hypothesized that the presence of contrasting ancestry proportions between sex chromosomes and autosomes could reveal the direction of gene flow in hybridizing populations54. We bioinformatically inferred sex by calculating Z chromosome to autosome depth ...
Physiolgically, NMDA receptors mediate synaptic plasticity by acting as a coincidence detector. Only those synapses that show temporally and spatially discrete... Koch,J Horst,Szecsey,... - 《Current Pharmaceutical Design》 被引量: 43发表: 2004年 加载更多来源...
