BACKGROUND This work aimed to study the homing evidence and the reparative effect of mesenchymal stem cells (MSCs) in the healing process of induced osteoarthritis in experimental animal model (donkeys). METHODS Twenty-seven donkeys were equally divided into 3 groups based on the observation period after induction of arthritis (3, 6 and 9 weeks) to(More)
OBJECTIVES This study was intended to verify the likelihood of homing of intra-articularily injected mesenchymal stem cells (MSCs) and its involvement in the healing process of experimentally induced, acute and chronic, partial chondral defects in dogs. METHODS Partial thickness chondral defects were created on the lateral femoral condyle of stifle joint(More)
We achieved possibility of isolation, characterization human umbilical cord blood endothelial progenitor cells (EPCs), examination potency of EPCs to form new blood vessels and differentiation into cardiomyoctes in canines with acute myocardial infarction (AMI). EPCs were separated and cultured from umbilical cord blood. Their phenotypes were confirmed by(More)
Es gibt mannigfaltige Wege, virtuelles Gewebe herzustellen. Erste Schritte dorthin können über die Herstellung virtueller Zellen führen. Eine „Quaoaring“ genannte Methode wurde genutzt, um artifizielle Erythrozyten sowohl der Diskozyten- als auch der Echinozytenform zu erzeugen. Die Ergebnisse wurden mit Daten aus der Rasterelektronenmikroskopie und der(More)
Competing concepts exist regarding surgery for instance of the cleft lip and palate to date. Morphology-based simulations at histological scale may one day be used to help the surgeon predict the possible outcome of a variety of approaches. It however can be a challenge to generate volume meshes that are applicable to the mathematical modelling of(More)
Pneumopericardium is a rare finding that has been previously reported following spontaneous, traumatic, or iatrogenic causes. A 3-year old Golden Retriever dog was admitted with respiratory distress after falling from a height. Clinical and electrocardiographic findings were nonspecific. Thoracic radiography revealed hyperinflated lung with sharp outlining(More)
Diese Arbeit beschreibt einen neuen Algorithmus zur (semi)automatischen Segmentierung histologischer und zytologischer Präparate. Bedingt durch den Umstand, dass derartige Präparate teilweise nur wenige kontrastreiche Areale und kaum scharfe Konturen aufweisen, sind klassische Segmentierungsverfahren wenig Erfolg versprechend, die relevanten Strukturen zu(More)
Resveratrol (RSV), a polyphenolic compound and naturally occurring phytoalexin, has been reported to exert cardio-protective effects in several animal studies. However, the outcome of initial clinical trials with RSV was less effective compared to pre-clinical studies. Therefore, RSV treatment protocols need to be optimized. In this study we evaluated(More)
Ultrasonography is a valuable diagnostic tool that has been used for diagnosis of neonatal brain diseases. The purpose of the present study was to describe the sequential ultrasonographic appearance of the normal canine neonatal brain from birth till closure of the bregmatic fontanelle. In total, 16 clinically normal neonates of mixed breed dogs were used.(More)
