In contrast to mammalian transglutaminases (TGs), plant members of the superfamily are poorly characterized. In order to produce pure and active TG for its functional and structural studies, variants of maize chloroplast transglutaminase (TGZ, Patent WWO03102128) were sub-cloned into a pET28 vector and overexpressed in Escherichia coli BL21 (DE3) cells. The(More)
Trehalose (a non-reducing disaccharide) plays an important role in abiotic stress protection. It has been shown that using trehalose synthesis genes of bacterial origin, drought and salt tolerance could be achieved in several plants. A cassette harboring the AtTPS1 gene under the control of the CaMV35S promoter and the Bialaphos resistance gene was inserted(More)
BACKGROUND Hallmarks of the pathogenesis of rotator cuff disease (RCD) include an abnormal immune response, angiogenesis, and altered variables of vascularity. Degenerative changes enhance production of pro-inflammatory, anti-inflammatory, and vascular angiogenesis-related cytokines (ARC) that play a pivotal role in the immune response to arthroscopic(More)
PURPOSE The purpose of this study was to evaluate the clinical and sequential imaging follow-up results at a mean of 36 months after an arthroscopic technique for implantation of matrix-encapsulated autologous chondrocytes for the treatment of articular cartilage lesions on the femoral condyles. METHODS Ten patients underwent arthroscopic implantation of(More)
The economic importance of the palm Bactris gasipaes is growing in the Neotropoical region. We collected leaflets from plants under a chemical fertilization regime and a population of 5000 plants per hectare, in Costa Rica. The variety, Diamantes 10, has an ascendency fom the upper Amazon basin. We used Harries hematoxiline, eocine and standard light(More)
Trehalose is a non-reducing disaccharide of glucose that occurs in a large number of organisms, playing an important role in desiccation and heat stress protection. Trehalose accumulation has proven to be an effective way of increasing drought tolerance in both model plants such as tobacco and important crops such as potato or rice. In this work we aim to(More)
