Background: Recently, cartilage tissue engineering is the best candidate for regeneration of cartilage defects. We evaluated the potential of fibrin and PLGA/fibrin scaffolds in providing a suitable environment for growth and chondrogenic differentiation of human adipose derived stem cells (hADSCs) in the presence of icariin. Method: The Three-dimensional...

The aim of this study was the determination of the pressure-derived collateral fractional flow reserve (FFR(coll)) in patients with three vessel disease and chronic occlusion of the right coronary artery undergoing surgical complete revascularization with the off-pump technique. The angiograms of eight patients were preoperatively analysed to quantify collaterality. FFR(coll) was determined bef...

Metastasis is a major cause of mortality and morbidity in osteosarcoma (OS) patients. To monitor tumor dissemination, we assessed the circulating tumor burden in OS patients by semiquantitative reverse transcription-PCR using osteocalcin, osteonectin, osteopontin, and type I collagen (COLL) mRNAs as molecular markers. We distinguished levels of the mRNAs in peripheral blood between OS patients ...

Type IV collagen (Coll IV), a component of the extracellular matrix, stimulates motility in the A2058 human melanoma cell line, a response that is inhibited by pertussis toxin (PT). Fibronectin (FN)-induced chemotaxis in this cell line is not affected by PT. To understand the mechanism of cellular signaling, single cell intracellular Ca2+ responses to Coll IV and FN were studied using Fura-2 an...

When fibroblasts are cultured in contracting collagen matrices, matrix metalloproteinase-1 (MMP-1, collagenase-1) is induced. In the present study we demonstrate that p38alpha mitogen-activated protein kinase (p38alpha MAPK) plays a bi-directional role in the MMP-1 response to contracting floating collagen lattices (fl-coll). fl-coll, but not attached collagen lattices (att-coll), co-ordinately...

Biomaterials with high osteogenic activity are desirable for sufficient healing of bone defects resulting from trauma, tumor, infection, and congenital abnormalities. Synthetic materials mimicking the structure and composition of human trabecular bone are of considerable potential in bone augmentation. In the present study, a zinc (Zn)-doped mesoporous hydroxyapatite microspheres (Zn-MHMs)/coll...

As a result of automated construction methods, which many construction companies have worked on these days. Consequently, the following construction planning systems are needed .1) the best framework partition plan, 2) the best layout plan of the hardware and the best usage plan of workers at the construction site, 3) the output of the stage of execution works, in a short period of time. This s...
