A learning object can be considered as a unit of instructional content for which a metadata record describing its characteristics and intended educational usage is provided. Metadata records can be used to develop effective search and location of learning objects, and also to develop automated or semi-automated selection and composition tools. In(More)
BACKGROUND A long term research goal of venomics, of applied importance for improving current antivenom therapy, but also for drug discovery, is to understand the pharmacological potential of venoms. Individually or combined, proteomic and transcriptomic studies have demonstrated their feasibility to explore in depth the molecular diversity of venoms. In(More)
Mobile learning is considered an evolution of e-learning that embraces the ubiquitous nature of current computational systems in order to improve teaching and learning. Within this context it is possible to develop mobile applications oriented to learning, but it is also important to assess to what extent such applications actually work. In this paper we(More)
E nvenoming resulting from snake bites is an important public health hazard in many regions, particularly in tropical and subtropical countries [1–3]. Although antivenoms are being produced by various laboratories in every continent, the burden of snake bite envenoming— causing both morbidity and mortality—still has a great impact on the population and on(More)
Snakebite envenoming constitutes a serious medical condition that primarily affects residents of rural communities in Africa, Asia, Latin America, and New Guinea [1,2]. It is an occupational, environmental, and domestic health hazard that exacerbates the already impoverished state of these communities [3]. Conservative estimates indicate that, worldwide,(More)
Protein-protein interfaces have crucial functions in many biological processes. The large interaction areas of such interfaces show complex interaction motifs. Even more challenging is the understanding of (multi)specificity in protein-protein binding. Many proteins can bind several partners to mediate their function. A perfect paradigm to study such(More)
Standards and specifications widely accepted and used lay the foundations to enable and facilitate the interoperability among systems, and the software maintenance and reuse, especially within the scope of learning objects' search systems. One of these standards is the SQI (Standard Query Interface) specification by the European Committee for(More)
Envenomations by the snake Bothrops asper are characterized by prominent local tissue damage (i.e. myonecrosis), blistering, hemorrhage and edema. Various phospholipases A2 and metalloproteinases that induce local pathological alterations have been purified from this venom. Since these toxins induce a conspicuous inflammatory response, it has been(More)
BACKGROUND Viperid snakebite envenoming is characterized by prominent local tissue damage, including muscle necrosis. A frequent outcome of such local pathology is deficient skeletal muscle regeneration, which causes muscle dysfunction, muscle loss and fibrosis, thus provoking permanent sequelae that greatly affect the quality of life of patients.
