Healing properties of surface-coated polycaprolactone-co-lactide scaffolds: A pilot study in sheepRentsch, Claudia, Schneiders, Wolfgang, Hess, Ricarda, Rentsch, Barbe, Bernhardt, Ricardo, Spekl, Kathrin, Schneider, Konrad, Scharnweber, Dieter, Biewener, Achim, Rammelt, Stefan 11 October 2019 (has links)
The aim of this pilot study was to evaluate the bioactive, surface-coated polycaprolactone-co-lactide scaffolds as bone implants in a tibia critical size defect model. Polycaprolactone-co-lactide scaffolds were coated with collagen type I and chondroitin sulfate and 30 piled up polycaprolactone-co-lactide scaffolds were implanted into a 3 cm sheep tibia critical size defect for 3 or 12 months (n¼5 each). Bone healing was estimated by quantification of bone volume in the defects on computer tomography and microcomputer tomography scans, plain radiographs, biomechanical testing as well as by histological evaluations. New bone formation occurred at the proximal and distal ends of the tibia in both groups. The current pilot study revealed a mean new bone formation of 63% and 172% after 3 and 12 months, respectively. The bioactive, surface coated, highly porous three-dimensional polycaprolactone-co-lactide scaffold stack itself acted as a guide rail for new bone formation along and into the implant. These preliminary data are encouraging for future experiments with a larger group of animals.

Comparative performance evaluation of Horro and Menz sheep of Ethiopia under grazing and intensive feeding conditionsAwgichew, Kassahun 20 December 2000 (has links)
Die vorliegende Untersuchung wurde am International Livestock Centre for Africa (ILCA), jetzt International Livestock Research Institute (ILRI) auf der Versuchsstation Debre Birhan in Äthiopien durchgeführt. Diese Untersuchung ist Teil eines panafrikanischen ILRI-Forschungsprogramms zur Untersuchung und Charakterisierung einheimischer kleiner Wiederkäuer im Sub-Saharischen Afrika auf genetische Resistenz gegenüber Endoparasiten. Das Ziel dieser Arbeit bestand darin, Ergebnisse zu verschaffen, die zum Verständnis der relativen Leistung zweier äthiopischer Hochlandschafrassen (Horroschaf und Menzschaf) unter Stationsbedingungen dienen sollen. Horro-Lämmer (2,43±0,03 kg) waren signifikant (p / This study has been carried out at the former International Livestock Centre for Africa (ILCA), that is now the International Livestock Research Institute (ILRI) experiment station at Debre Birhan, Ethiopia. This research is part of an ILCA (now ILRI) Pan-African research programme designed to investigate and characterise genetic resistance to endoparasites in some indigenous small ruminants in sub-Saharan Africa. The present study was, therefore, undertaken in an attempt to generate information that may contribute towards the understanding of the relative performance of two highland sheep (Horro and Menz) of Ethiopia under station management conditions. Horro lambs were significantly heavier (P
