Introduction An intra-operative technique of collecting and concentrating the buffy coat from a unit of blood has previously been characterized. This autologous approach may be an alternative to other potential osteoinductive therapies such as bone morphogenetic proteins, or conceptually may be used as a synergistic carrier for BMPs or ostetoprogenitor cells. Platelets contain a number of growt...

Diagnosis of opisthorchiasis is confirmed by the presence of characteristic eggs and worms. However, misdiagnosis may occur in light infections, and also due to the morphological similarity of opisthorchid eggs to other species. A finding of specific immune mediators can help confirm infection. This study used indirect ELISA to detect total IgG and IgG(1-4) with selected antigens of Bithynia si...

Only certain serotypes of Salmonella represent 99% of all human clinical isolates. We determined whether the phylogenetic distribution of fimbrial operons would account for the host adaptations observed for Salmonella serotypes. We found that three fimbrial operons, fim, lpf, and agf, were present in a lineage ancestral to Salmonella. While the fim and agf fimbrial operons were highly conserved...

Bridging large bone defects with mesenchymal stromal cells-seeded scaffolds remains a big challenge in orthopedic surgery, due to the lack of vascularization. Within such a cell-scaffold construct, cells are exposed to ischemic conditions. When human mesenchymal stem cells (hMSCs) encounter hypoxic conditions, they show higher cell proliferation than at ambient oxygen levels. However, when hMSC...

To enhance the stability of continuous welded rail (CWR) tracks, frictional sleepers have been developed. The are new types with grooves on bottom, and different bottom improve lateral resistances at magnitudes. In this study, single sleeper push test (SSPT) its model discrete element method (DEM) were carried out to confirm how much arrowhead groove (AGF) increases resistance ballasted track. ...

With the aim of gauging their potential as conducting or superconducting materials, we examine the crystal structures and magnetic properties of the roughly one hundred binary, ternary, and quaternary Ag(II) and Ag(III) fluorides in the solid state reported up to date. The Ag(II) cation appears in these species usually in a distorted octahedral environment, either in an [AgF](+) infinite chain ...

A series of 50 specimens of Hodgkin's disease and 10 of reactive follicular hyperplasia were examined by means of indirect immunoperoxidase staining with a monoclonal antibody AGF 4.48: this is known to bind to 3-fucosyl-N-acetyllactosamine, which, in particular, is expressed by granulocyte series cells. Most Reed-Sternberg and many Hodgkin's cells were labelled by the antibody after pretreatme...

Several authors have reported the presence of ascending giant fibres (AGF) in the nerve cord of the American cockroach, Periplaneta americana (Pumphrey & Rawdon-Smith, 1937; Roeder, 1948; Hess, 1958). Roeder (1948) presented a scheme showing a synaptic link (in the 6th abdominal ganglion) between the cereal sensory neurones and the AGF, the latter then ascending as continuous fibres to the meta...

Charge-transfer insulators are the parent phase of a large group today's unconventional high-temperature superconductors. Here we study experimentally and theoretically interband excitations charge-transfer insulator silver fluoride ${\mathrm{AgF}}_{2}$, which has been proposed as an excellent analog oxocuprates. Optical conductivity resonant inelastic x-ray scattering on ${\mathrm{AgF}}_{2}$ p...

The present work illustrates a formulation to evaluate spectral integral that represent the array Green’s function (AGF) of large finite planar phased array for observation points close to the array contour. The procedure is based on the AGF representation in terms of a double spectral integral, whose numerical evaluation takes advantage of the exponential attenuation on a proper integration pa...
