In an era of energy crisis, biomass-based bioenergy research has attracted the attention of R&D managers and policy makers around the world. This study explores the structural and dynamic patterns of biomass-based bioenergy research. We measure the profile of biomass research on both macro scales (nations) and meso level (institutions) in an international(More)
Steroid receptor co-activator-3 (SRC-3/AIB1) is an oncogene that is amplified and overexpressed in many human cancers. However, the molecular mechanisms that regulate 'activated SRC-3 oncoprotein' turnover during tumorigenesis remain to be elucidated. Here, we report that speckle-type POZ protein (SPOP), a cullin 3 (CUL3)-based ubiquitin ligase, is(More)
BACKGROUND There is a continuous demanding for tightly regulated prokaryotic expression systems, which allow functional synthesis of toxic proteins in Escherichia coli for bioscience or biotechnology application. However, most of the current promoter options either are tightly repressed only with low protein production levels, or produce substantial protein(More)
The relationship between economic growth, expansion of urban land area and the broader issue of cultivated land conversion in China has been closely examined for the late 1980s and 1990s. Much less is known about recent urban expansion and if the effects of economic growth on this expansion have changed over time. This paper updates estimates of urban(More)
Diffuse astrocytoma of (WHO grade II) has a tendency to progress spontaneously to anaplastic astrocytoma (WHO grade III) and/or glioblastoma (WHO grade IV). However, the molecular basis of astrocytoma progression is still poorly understood. In current study, an essential initial step toward this goal is the establishment of the taxonomy of tumors on the(More)
