autologous fat transfer offers many qualities of a ideal soft tissue filler. main advantages of fat grafting ensue from the fact that the lipoaspirate tissue is an abundant source of regenerative pluripotential cells. however, the reported rates of fat cell survival vary greatly in the medical literature (10-90%). different techniques of harvesting, processing, and reinjecting the fat cells are...

background cartilage tissue has limited regenerative capacity and the management of cartilage defects has always been a challenging issue. platelet-rich plasma (prp) has been recently been used to improve healing of cartilage defects. in the present experiment, we aimed to investigate the effects of prp on regeneration capacity as well as survival of the cartilage grafts in a rabbit model. meth...

Abstract A case of micronodular T-cell/histiocyte-rich B-cell lymphoma of the spleen who had a prior diagnosis of small lymphocytic lymphoma is presented. Micronodular T-cell/histiocyte-rich B-cell lymphoma of the spleen was first described in 2003, and very few cases have been reported since then. This is the first reported case supervening in a patient with pre-existing chronic lymphocytic ly...

patients and methods seventy patients with chronic partial supraspinatus tears in magnetic resonance imaging were randomized into two groups; prp (n = 35) and pt (n = 35). before the treatment, at the end of the treatment and at the 12th month after the end of the treatment, range of motion (rom), visual analog scale (vas) for pain, disabilities of arm, shoulder and hand questionnaire (dash), n...

Dual phase (a þ b) copper–tin alloys were synthesized from elemental nanoparticle precursors following consolidation, annealing and quenching steps. The precursors were derived from the sequential reduction of tin and copper salts in ethanolic solution. The dual phase microstructure exhibits a duplex character with a mixture of Cu-rich and Sn-rich (a þ b) regions. 2004 Published by Elsevier Ltd...

By Monte Carlo simulations in the constant-temperature--constant-pressure ensemble a planar interface between unmixed A-rich and B-rich phases of a binary (A, B) alloy on a compressible diamond lattice is studied. No significant capillary wave broadening of the concentration profile across the interface is observed, unlike lattice models of incompressible mixtures and fluids. The distortion of ...

Several functionalized benzo[1,2-b:3,4-b':5,6-d'']trithiophenes have been synthesized and characterized. The fully planar and highly electron-rich material shows great promise as the donor constituent in donor-acceptor type copolymers for use in organic electronics. As a proof of concept, a copolymer with the electron acceptor, 2,1,3-benzothiadiazole, has been prepared. Side-chain modifications...

inorganic polyphosphates (polyp) are linear polymers of few to several hundred orthophosphate residues, linked by energy-rich phosphoanhydride bonds. four isolates had been screened from soil sample. by maldi-tof analysis, they were identified as bacillius cereus, acinetobacter towneri, b. megaterium and b. cereus. the production of polyp in four isolates was studied in phosphate uptake medium ...

In the spectrum of diffuse large B-cell lymphomas (DLBCL), both T-cell/histiocyte-rich large B-cell lymphoma (TCHRBCL) and most lymphomatoid granulomatosis (LG) cases are characterized by the relative rarity of the neoplastic B-cell population, with respect to the overwhelming non-neoplastic counterpart of T cells or histiocytes. Here we report a case of aggressive B-cell lymphoma with unusual ...
