This article reports findings from a study of attitudes of 259 African American and White child welfare workers. They were asked about their views of the role of race in child welfare decisions and about the appropriateness of placement of children with gay and lesbian and single foster/adoptive parents. African American child welfare workers were more likely that White workers to believe that ...

Type Ia SNe (SNe Ia) are thought to come from carbon–oxygen white dwarfs that accrete mass from binary companions until they approach the Chan-drasekhar limit, ignite carbon, and undergo complete thermonuclear disruption. A survey of the observed types of binaries that contain white dwarfs is presented. We propose that certain systems that seem most promising as SN Ia progenitors should be more...

Recently, regular and white mineral trioxide aggregate (MTA) are being used in Dentistry as retrofilling materials. Genotoxicity and cytotoxicity tests form an important part of cancer research and risk assessment of potential carcinogens. Thus, the goal of this study was to examine the genotoxicity and cytotoxicity of regular and white MTA in vitro by the single cell gel (comet) assay and tryp...

Diffusion tensor imaging (DTI) tractography allows perform virtual dissections of white matter pathways in the living human brain. In 2002, Catani et al. published a method to reconstruct white matter pathways using a region of interest (ROI) approach. The method produced virtual representations of white matter tracts faithful to classical post-mortem descriptions but it required detailed a pri...

Single cell discharges were recorded in vitro from thin sections of cerebellum of the guinea-pig prepared vertical to the cortical surface and incubated in artificial media. White matter stimulation induced antidromic, mossy and climbing fiber responses in neurons in the Purkinje cell layer. Spontaneous discharges were observed in both Purkinje cell and granular layers. In the Purkinje cell lay...
