Objective(s): In this study, the effect of electrospun fiber orientation on proliferation and differentiation of mesenchymal stem cells (MSCs) was evaluated. Materials and Methods: Aligned and random nanocomposite nanofibrous scaffolds were electrospun from polylactic acid (PLA), poly (vinyl alcohol) (PVA) and calcium carbonate nanoparticles (nCaP). The surface morphology of prepared nanofibrou...

The aim of the present study was to evaluate the efficacy of the vacuum-assisted closure (V.A.C.) system in the treatment of early hip joint infections. 28 patients (11 m/17 f; mean age 71 y. [43-84]) with early hip joint infections have been treated by means of the V.A.C.-therapy. At least one surgical revision [1-7] has been unsuccessfully performed for infection treatment prior to V.A.C.-app...

2 There has been great interest in organic semiconductor materials composed of molecules such as sexithiophene derivatives and pentacene for organic thin film transistors (TFTs), due to their high field effect mobilities, which approach that of amorphous silicon. It is thought that the high mobilities observed in these materials are due to intermolecular interactions which lead to larger grain ...

In the issue of Lancet of September 30, 2000, Bonn presented a concise update on the current use and benefit of maggots in wound therapy [1]. To improve the acceptance of live maggots, facilitate their use and avoid physical discomfort, we have recently introduced the Biobag [2] (fig. 1A). Live larvae are enclosed between two 0.5-mm-thin layers of a polyvinylalcohol hydrosponge, which are heat ...

Zinc oxide nanoparticles have been synthesized by chemical reaction method.  Polyvinyl alcohol (PVA) composite film filled with nanometric, monodispersed zinc oxide nano particles prepared by PVA solution and nanozinc oxide. Polymer blend with ZnO nanoparticle composite film has prepared by casting technique.  The property of nano composites depends greatly on the chemistry of polymer matrices....

In many clinical diagnostics, skin serves as a measurement window for quantitative assessments of physiological health. Prominent examples are in biopotential recordings that yield insights into cardiovascular activity, skeletal muscle behaviour and brain function through electrocardiograms, electromyograms and electroencephalograms, respectively. Signals in the latter two cases can also serve ...

V2O5 is used to substitute Ta2O5 site of the SrBi2Ta2O9 ceramics to form SrBi2Ta2-xVxO9 composition, where 0.1 x 0.4 ≦ ≦ . The sintering and the dielectric properties of SrBi2Ta2-xVxO9 ceramics have been developed. For all SrBi2Ta2-xVxO9 composition, the crystal intensities of the (0,0,l) planes increase with the increase of sintering temperature and saturate at 1050C-sintered ceramics, and the...
