Autologous chondrocyte implantation is an established option for the treatment of full-thickness cartilage defects of the knee. Open implantation has a high morbidity. On a resorbable polymer fleece, autologous chondrocytes can be implanted arthroscopically. Transosseous anchoring assures high initial stability of the implant. Tibial defects can be addressed. The arthroscopic technique for the ...

Grazing ability is difficult to record in animals under free-ranging conditions without sophisticated methods. Alternatively, grazing ability may be indirectly inferred from changes in BW and production characteristics during the grazing period. The present study investigated the effect of grazing on resource-limited rangelands on BW, wool characteristics, and offspring weaning weights in nine ...

Polyethylene terephthalate (PET) is one of the world’s most used plastics. Amenable to both mechanical and chemical recycling processes, PET also commonly recycled. Chemical processes include glycolysis, which produces bis(2-hydroxyethyl) (BHET); this then re-polymerised form new PET. One novel method for glycolysis involves microwave irradiation water bottles in presence a catalyst and, notabl...

Fiber fragments are one of the dominant types microplastics in environmental samples, suggesting that synthetic textiles a potential source to environment. Whereas release during washing is already well studied, much less known about abrasion processes. The may induce fibrillation fibers and therefore result formation finer fiber fragments. aim this study was investigate influence on microplast...

A pedigree file consisting of 5860 individuals, 167 sires and 1582 dams collected at Makooei sheep breeding station (MSBS) during a period of 24 years (1990 to 2013) was used to calculate the inbreeding coefficients to reveal any probable effects of inbreeding (F) on the studied traits. The studied traits were classified to the five main groups including body weight, Kleiber ratio, body measure...

BACKGROUND collagenous and noncollagenous membranes have been investigated in many animal systems but their effects in the macaque model are unknown. OBJECTIVE to determine subcutaneous cellular reactions and degradation characteristics following implantation of collagenous and noncollagenous membranes in a macaque model. METHODS six adult male Macaca fascicularis, aged above 7 years, were ...
