Adv Appl Bioinform Chem. 2008;1:85-98. doi: 10.2147/aabc.s4133. Epub 2008 Oct 30.

There is a need to identify the regulatory gene interaction of anticancer drugs on target cancer cells. Whole genome expression profiling offers promise in this regard, but can be complicated by the challenge of identifying the genes affected by...

Weakening density dependence from climate change and agricultural intensification triggers pest outbreaks: a 37-year observation of cotton bollworms.

Ecology and evolution

Ouyang F, Hui C, Ge S, Men XY, Zhao ZH, Shi PJ, Zhang YS, Li BL.
PMID: 25535553
Ecol Evol. 2014 Sep;4(17):3362-74. doi: 10.1002/ece3.1190. Epub 2014 Aug 12.

Understanding drivers of population fluctuation, especially for agricultural pests, is central to the provision of agro-ecosystem services. Here, we examine the role of endogenous density dependence and exogenous factors of climate and human activity in regulating the 37-year population...

Free-radical cascade alkylarylation of alkenes with simple alkanes: highly efficient access to oxindoles via selective (sp3)C-H and (sp2)C-H bond functionalization.

Organic letters

PMID: 24354601
Org Lett. 2014 Jan 17;16(2):382-5. doi: 10.1021/ol4032478. Epub 2013 Dec 19.

A copper-catalyzed alkylarylation of alkenes with simple alkanes was achieved, which not only provided an efficient method to prepare various alkyl-substituted oxindoles, but also represented a novel strategy for selective sp(3) C-H functionalization/C-C bond formation via a free-radical cascade...

Synthesis of dibenzo[c,e]oxepin-5(7H)-ones from benzyl thioethers and carboxylic acids: rhodium-catalyzed double C-H activation controlled by different directing groups.

Angewandte Chemie (International ed. in English)
