The aim of this report is to review the current state of the art in content-based image retrieval (CBIR), a technique for retrieving images on the basis of automatically-derived features such as colour, texture and shape. Our findings are based both on a review of the relevant literature and on discussions with researchers and practitioners in the field.(More)
Accumulating epidemiological evidence supports the notion of brain reserve, but there has been no investigation of neurobiological change associated with brief mental activation training in humans. Healthy older individuals were therefore investigated with magnetic resonance spectroscopy (MRS) in different brain regions before and after 5 weeks of focused(More)
The patched gene (Ptc) is a member of the hedgehog signaling pathway which plays a central role in the development of many invertebrate and vertebrate tissues. In addition, Ptc and a number of other pathway members are mutated in some common human cancers. Patched is the receptor for the hedgehog ligand and in the mouse ablation of the Ptc gene leads to(More)
We present the architecture of 3D TerraFly, a three-dimensional extension of TerraFly, which is a Web-enabled geographic information system designed for visualization, analysis and composition of remotely-sensed imagery. 3D TerraFly has a client/server architecture. The client-side application is a web-embedded component called the 3D TerraFly Viewer that(More)
The limited availability and potential to culture primary human brain cells means that there is still a need for cell lines that reliably model human neurons and glial cells. The human-derived NTera2/D1 (NT2) cell line is a promising tool from which both neuronal (NT2N) and astrocytic (NT2A) cells can be derived in vitro. Here we have investigated the(More)
The domestic longline fishery operating off the east coast of Australia incidentally takes over 80 non-target species. A significant amount of this non-target catch is retained as byproduct. Total retained byproduct increased through the 1990s to peak at just over 1300 mt (19.6% of total retained catch) in 2002. Due to the difficult economic outlook faced(More)
Neuroinflammation contributes to the pathogenesis of several neurological disorders and pericytes are implicated in brain inflammatory processes. Cellular inflammatory responses are orchestrated by transcription factors but information on transcriptional control in pericytes is lacking. Because the transcription factor CCAAT/enhancer binding protein delta(More)
