We present microparticle image velocimetry measurements of suspended microparticles of diameters from 0.6 to 10 μm undergoing acoustophoresis in an ultrasound symmetry plane in a microchannel. The motion of the smallest particles is dominated by the Stokes drag from the induced acoustic streaming flow, while the motion of the largest particles is dominated by the acoustic radiation force. For a...

A funder is incorrectly omitted from the Funding statement. The correct Funding statement is as follows: This work was supported by a Polish-German cooperation grant (S007/P-N/2007/01); National Science Center grant N N401 324739; EMBO Short-Term Fellowship to E.

We observe distinct regimes of orbital angular momentum (OAM) transfer from two-dimensional Bessel-shaped acoustic vortices to matter. In a homogeneous diphasic mixture of microparticles and water, slow swirling about the vortex axis is seen. This effect is driven by the absorption of OAM across the mixture, the motion following the OAM density distribution. Larger particles are formed into clu...

We present a platform for parallelized manipulations of individual polarizable micron-scale particles (i.e., microparticles) that combines negative dielectrophoretic forcing with the passive capture of hydrodynamic weir-based trapping. Our work enables manipulations using ejection- andor exclusion-based methods. In ejection operations, we unload targeted weirs by displacing microparticles from ...

the k-th semi total point graph of a graph g, , ‎is a graph‎ obtained from g by adding k vertices corresponding to each edge and‎ connecting them to the endpoints of edge considered‎. ‎in this paper‎, a formula for laplacian polynomial of in terms of‎ characteristic and laplacian polynomials of g is computed‎, ‎where is a connected regular graph‎.the kirchhoff index of is also computed‎.

background menstrual blood-derived stem cells (menscs) are a novel source of stem cells that can be easily isolated non-invasively from female volunteered donor without ethical consideration. these mesenchymal-like stem cells have high rate of proliferation and possess multi lineage differentiation potency. this study was undertaken to isolate the menscs and assess their potential in differenti...

background: considering the increasing number of patients with hemophilia and infrastructure requirements for a comprehensive approach, development of a recombinant factor has become a milestone. the objective of this study was to assess the safety, efficacy and non inferiority of safacto (recombinant factor viii) compared with plasma-derived factor in the treatment of hemophilia a. methods: 10 ...

the onset of infections by leishmania parasites mainly caused by amastigote growth inside the macrophages. one of the important properties of lesion-derived amastigote is thought to be the attachment of various host proteins including immunoglobulins on the surface of amastigote. in this study, the presence of immunoglobulins on the surface of lesion-derived amastigotes was detected by western ...

abstract background autologus platelet gel is easy to prepare and is relatively low cost. the aim of this study was to prepare and evaluate in vitro efficacy of autologus platelet gel. materials and methods in this experimental study, platelet concentrate and platelet poor plasma were prepared with aphaeresis method. thrombin was prepared by mixing the plasma with calcium. thrombin activity lev...
