The present study evaluated the human mesenchymal stem cells (hMSCs) isolated from skin (hSMSC), bone marrow (hBMSC) and dental follicle (hDFMSC) tissues on their in vitro and in vivo osteogenic potential using demineralized bone matrix (DBM) and fibrin glue scaffold. Cells originated from three distinct tissues showed positive expressions of CD44, CD73,(More)
The present study compared mesenchymal stem cells derived from umbilical cord matrix (UCM-MSCs) with bone marrow (BM-MSCs) of miniature pigs on their phenotypic profiles and ability to differentiate in vitro into osteocytes, adipocytes and neuron-like cells. This study further evaluated the therapeutic potential of UCM-MSCs in a mouse Parkinson's disease(More)
The frictional behavior during manipulation of a single ZnO nanowire with a mass of about 18.7 ng placed horizontally on a Si wafer was examined using atomic force microscopy (AFM). The frictional force measured was in the range of 36.4 nN to 69.3 nN, which corresponded to extremely high friction coefficients of 242 and 462, respectively. However, when the(More)
Transthyretin (TTR) is a human disease-associated amyloidogenic protein that has been implicated in senile systemic amyloidosis (SSA) and familial amyloidotic polyneuropathy (FAP). FAP typically results in severe and early-onset disease, and the only therapy established so far is liver transplantation; thus, developing new strategies for treating FAP is of(More)
Surface morphology is one of the critical parameters that affect the frictional behavior of two contacting bodies in relative motion. It is important because the real contact area as well as the contact stiffness is dictated by the micro- and nano-scale geometry of the surface. In this regard, the frictional behavior may be controlled by varying the surface(More)
A detailed photophysical analysis of 4-hydroxy-5-phenylpyrido[3,2,1-jk]carbazol-6-one (HPPCO) is presented. When exposed to UV light, the compound produced deep blue to green luminescence, depending on the solvent. The luminescence peak shifts with the Gutmann donor number (DN) of the solvent and the proton substitution affects luminescence; a correlation(More)
2,6-Didodecyl-4,8-diphenyl-benzo[1,2-d;4,5-d']bisthiazole (3) and 2,6-didodecyl-4,8-dipyrrole-2-yl-benzo[1,2-d;4,5-d']bisthiazole (5) were synthesized, and their optical properties were investigated in solution and in the solid state. Compounds 3 and 5 were excited with the 325 nm He-Cd laser line to produce blue and green luminescence, respectively. The(More)
