—Surface roughness has a significant effect on the relationship between radar hackscattcr and soil moisture. In order to use cxistinR radar satellite data for soil moisture, roughness effects must be corrected. A technique is presented that utilises Ihe data bases from soil erosion sludies and soil moisture remote sensing investigations to provide firsl… (More)
The Beclin-1 protein is essential for the initiation of autophagy, and recent studies suggest this function may be compromised in Alzheimer's disease (AD). In addition, in vitro studies have supported a loss of function of Beclin-1 due to proteolytic modification by caspases. In the present study, we examined whether caspase-cleavage of Beclin-1 occurs in… (More)
Cytokines are important for breast cell function, both as trophic hormones and as mediators of host defense mechanisms against breast cancer. Recently, inducible feedback suppressors of cytokine signalling (SOCS/JAB/SSI) have been identified, which decrease cell sensitivity to cytokines. We examined the expression of SOCS genes in 17 breast carcinomas and… (More)
Regulation of gene expression is critical to the proper development of neuronal cells. The methyl-CpG binding protein 2 (MeCP2) operates as a transcriptional repressor by facilitating histone deacetylation and DNA methylation-dependent transcriptional silencing. This study examined the importance of MeCP2 in the regulation of neurite formation in PC12… (More)
In this paper, the approaches to introducing security policy into Role-Based Access Control (RBAC) and the Common Data Security Architecture (CDSA) are proposed. We apply security policy to a role's privileges in RBAC. The extended CDSA supports user-definable trust policy enforcement. Furthermore, a policy description language is discussed.
Although the risk factor for apolipoprotein E (apoE) polymorphism in Alzheimer's disease (AD) has been well described, the role that apoE plays in other neurodegenerative diseases, including Pick's disease, is not well established. To examine a possible role of apoE in Pick's disease, an immunohistochemical analysis was performed utilizing a novel… (More)
Zebrafish (Danio rerio) are progressively becoming more popular as a model organism for research. The use of zebrafish is advantageous for several reasons. Zebrafish are small in size, exhibit high fecundity, rapidly generate, are transparent during development and are easily maintained in large numbers. Using zebrafish as a model organism, the aim of this… (More)
