22-151 ABSTRACT The main objective of this study was to evaluate the effectiveness and improved productivity of reduced tillage pasture renovation methods in the establishment of triple species pasture mixtures into an existing naturalized stand. Experimental treatments, 2 (low and high stocking rates) by 2 (frostand sod-seeding methods) factorial with an additional non-renovated pasture contro...
This study aimed to study the effects of initial cell density and in vitro culture method on the construction of tissue-engineered bone grafts and osteogenic activities. Human mesenchymal stem cells (hMSCs) were seeded onto cubic scaffolds prepared from demineralized bone matrix (DBM) by three methods - static, hydrodynamic, or fibrin hydrogel-assisted seeding. The resulting cell-scaffold const...
Methods and Materials We tested cell retention on the scaffold by confocal microscopy at 7, 15, 20, 40, 60, 90 and 120 minutes after seeding, and the molecular profile (collagen II, aggrecan, Sox9, HAPLN1) of chondrocytes seeded at 20 minutes and 4 days (preoperative seeding method). Fifteen OrthoACITM patients with 25 cartilage defects were assessed by arthroscopic or magnetic resonance imagin...
the main method of rice planting in iran is transplanting. due to poor mechanization of rice production, this method is laborious and costly. the other method is direct seeding in wet lands which is performed in the one third of rice cultivation area of the world. the most important problem in this method is high labor requirement of weed control. in order to compare the different rice planting...
A recent development in the field of tissue engineering is the rise of all-biologic, scaffold-free engineered tissues. Since these biomaterials rely primarily upon cells, investigation of initial seeding densities constitutes a particularly relevant aim for tissue engineers. In this study, a scaffold-free method was used to create fibrocartilage in the shape of the rabbit knee meniscus. The obj...
