Carbon thin films containing many fine carbon particles were deposited by a pulsed ArF laser ablation technique assisted by inductively coupled plasma (ICP). The sizes of the particles were found to be ~ 100 nm. The particles seemed to be coagulated from several finer particles of size ~ 10 nm. When ICP was applied to a plume, the shape of the coagulated particles became spherical. The deposite...

We propose the use of a pulsatile high-speed irrigation device during video-assisted thoracoscopy for retained, in part coagulated hemothorax. Blood clots and membranes adhering to intrathoracic structures are easily removed by the water jet without damaging underlying structures. The efficient dilution of the sticky retained blood and the fragmented coagula enable their quick removal over a su...

Folate is a source of one-carbons necessary for DNA methylation, a critical epigenetic modification necessary for genomic structure and function. The use of supplemental folic acid is widespread however; the potential influence on DNA methylation is unclear. We measured global DNA methylation using DNA extracted from samples from a population-based, double-blind randomized trial of folic acid s...

Background: In vitro angiogenesis assays were first described in the early 1980s, when it was found that endothelial cells form capillary-like structures (CLS) on matrices of collagen, laminin or fibrin. These assays have been useful in unravelling some of the molecular steps involved in angiogenesis, as well as in screening potential angiogenesis inhibitors. Aim: The aim of our current study w...

Methods Patients presenting to the emergency department within 2 hours of severe polytrauma were eligible if intubated either at the scene or in ED. Isolated head injuries and those not expected to survive 24 hours were excluded. EDTA anti-coagulated blood was drawn at 0hr (within 2 hours of injury), at 24 and 72hrs. Samples were immediately lysed, washed, stained and analysed using a standardi...

Pitman (1999) describes a duality relationship between fragmentation and coagulation operators. An explicit relationship is described for the two-parameter Poisson-Dirichlet laws, say PD(a, b), with parameters (α, θ) and (β, θ/α), wherein PD(α, θ) is coagulated by PD(β, θ/α) for 0 < α < 1, 0 ≤ β < 1 and −β < θ/α. This remarkable explicit agreement was obtained by combinatorial methods via excha...

BACKGROUND Angiogenesis, the development of new blood vessels, is an important process in tissue development and wound healing, but becomes pathologic when associated with solid tumor growth, proliferative retinopathies, and rheumatoid arthritis. Accurate and reliable qualification of neovascular (angiogenic) response, both in vitro and in vivo, is an essential requirement for the study of new ...
