AbsorbaSeal™ 5.6.7F vascular closure device: A good laboratory practice chronic study evaluating safety and efficacy in a healthy porcine model.

Objectives: Vascular closure devices (VCDs) are widely used for arteriotomy closure after percutaneous catheter-based procedures. In comparison to manual compression, VCDs have been associated with shorter time to hemostasis, shorter time to ambulation, and also decreased length of stay. Complexity of deployment, lack of immediate hemostasis, and residual deformity of the arterial wall remain as limitations of current VCDs.

Knowing, Being, and Doing: Aboriginal and Non-Aboriginal Collaboration in Cancer Services.

This qualitative inquiry explored the processes and practices of collaboration as experienced by a group of Australian multidisciplinary Aboriginal and non-Aboriginal health workers. Each worker had participated, for a period of 2 to 5 years, in an Australian Government-funded project in which a range of health initiatives led to improved access to cancer services by Aboriginal communities in a rural region of South Eastern Australia. Initiatives which addressed high rates of mortality from cancer, poor access to cancer screening, and engagement with cancer treatment were developed through the formation of close working relationships between Aboriginal and non-Aboriginal health workers.

Protocol for building a reference standard sequence library for DNA-based seafood identification.

With the recent adoption of a DNA sequencing-based method for the species identification for seafood products by the U.S. Food and Drug Administration (FDA), a library of standard sequences derived from reference specimens with authoritative taxonomic authentication was required.

The nature and origin of interstellar diamond.

Microscopic diamond was recently discovered in oxidized acid residues from several carbonaceous chondrite meteorites (for example, the C delta component of the Allende meteorite). Some of the reported properties of C delta seem in conflict with those expected of diamond. Here we present high spatial resolution analytical data which may help to explain such results.

Deuterium exchange during acid-demineralisation.

Isotopic analyses of residues prepared by demineralisation of the Murchison meteorite using D-labelled reagents provide evidence for measurable exchange of H-isotopes between residue and reagents. Precise quantification of this effect is precluded by substantial inhomogeneity of the meteoritic organic matter. A conservative estimate of the degree of exchange is 3 to 5% of the H pyrolysable as H2O.
