Genetic transformation of mature trees is difficult because adult tissues are recalcitrant to Agrobacterium tumefaciens infection and transformation and because transgenic mature events are less competent for regeneration. We have shown that reinvigoration allows manipulation of the vegetative phase to increase the potential for transformation and(More)
The main purpose of this paper is to show that once the video source coding is dependent on the channel characteristics, better performance can be achieved in terms of reconstructed video quality. Our study considers a fixed overall bit rate transmission of 64 kbit/s over error prone memoryless binary channels and the source coder is the ITU-T H.263 video(More)
HEVC is the latest video coding standard aimed to compress double to that of its predecessor standard H.264/AVC at the cost of increased coding complexity. Motion Estimation (ME) is one of its critical tools in the encoder whose complexity drastically increases due to the increase in coding block size to 64×64 and due to the introduction of(More)
The present study was undertaken to investigate, if the non-steroidal anti-inflammatory drug (NSAID) piroxicam (CAS 36322-90-4) Fast-Dissolving Dosage Form (FDDF) can be absorbed in the oral mucosa. Piroxicam FDDF was administrated under the tongue to rats with an oesophagus ligation (OL) to prevent the drug entering the stomach and in turn its absorption(More)
Catheter associated urinary tract infections are common during hospitalization due to the formation of bacterial biofilms on the indwelling device. In this study, we report an innovative biotechnology-based approach for the covalent functionalization of silicone catheters with antifouling zwitterionic moieties to prevent biofilm formation. Our approach(More)
Evaluation of the sequence selectivity, noncovalent association, and orientation of the DNA cross-linking agent azinomycin B on its duplex DNA receptor is described. A strong correlation between sequence nucleophilicity and cross-linking yield was observed, and steric effects due to the thymine C5-methyl group were identified. Detailed studies on the role(More)
BACKGROUND Tibial valgus, a known complication of leg lengthening with external fixation techniques, has been related to the stability of the bone-fixator system and, in particular, to pin loosening. A hydroxyapatite coating has been reported to enhance the quality of the bone-pin interface. The aim of this study was to compare the prevalence of axial(More)
