Knee involvement of soft tissue sarcomas is rare and very difficult to treat. Reconstruction of the extensor mechanism of the knee is essential to restore the functionality. Functional outcome is compromised by poor soft tissue coverage, adjuvant local radiotherapy, and resection of the extensor apparatus. No results were found in the literature as regard treatment by resection and reconstruction...
This study focuses on the valorisation of crude glycerol and sunflower meal (SFM) from conventional biodiesel production plants for the separation of value-added co-products (antioxidant-rich extracts and protein isolate) and for enhancing biodiesel production through microbial oil synthesis. Microbial oil production was evaluated using three oleaginous yeast strains (Rhodosporidium toruloides, Lipomyces...
Biodiesel is a biodegradable fuel that originates from a variety of oleaginous raw materials, although most studies have been traditionally based on vegetable oils. Rapeseed (Brassica napus) is the raw material most widely used in the production of biodiesel in temperate climate, i.e. central Europe, due to its physical properties and the content of oleic acid of its oil. However, this plant needs...
Utilization of by-products from oilseed-based biodiesel production (crude glycerol, rapeseed meal hydrolysates) for microbial polyhydroxyalkanoate (PHA) production could lead to the replacement of expensive carbon sources, nutrient supplements and precursors for co-polymer production. Batch fermentations in shake flasks with varying amounts of free amino nitrogen led to the production of poly(3-hydroxybutyrate-co-3-hydroxyvalerate)...
To evaluate the results of femoral shaft fractures treated by closed interlocked nailing, throughout an analysis of clinical and radiological findings.Retrospective study of 150 consecutive patients (156 femoral fractures) treated by closed interlocked nailing, over a period of 15 years (1987-2002). Fractures were classified and studied, analyzing the timing and type of surgical intervention, as well...
