PURPOSE Genome-wide association studies have recently identified single-nucleotide polymorphisms (SNP) in five loci at 5p15.33 (rs2736100, TERT), 8q24.21 (rs4295627, CCDC26), 9p21.3 (rs4977756, CDKN2A/CDKN2B), 20q13.33 (rs6010620, RTEL1), and 11q23.3 (rs498872, PHLDB1) to be associated with glioma risk. Because gliomas are heterogeneous in histology, molecular alterations, and clinical behavior...

Andrade et al. published on the May/June 2013 issue of this journal an interesting article on otorhinolaryngology (ENT) emergencies (‘‘Profile of otorhinolaryngology emergency unit care in a high complexity public hospital’’).1 The aim of this letter is to compare and comment what has been published to our data. We retrospectively reviewed all patients sent for urgent/emergent consultation to o...

EMGs were collected from 14 muscles with surface electrodes in 10 subjects walking 1.25-2.25 ms(-1) and running 1.25-4.5 ms(-1). The EMGs were rectified, interpolated in 100% of the stride, and averaged over all subjects to give an average profile. In running, these profiles could be decomposed into 10 basic patterns, 8 of which represented only a single burst. Muscles could be divided into a q...

The proteolytic activity of three Pseudomonas aeruginosa strains, ATCC 27853 - a reference strain, and two clinical isolates was tested. The activity was examined after culturing the bacteria in two different growth media: the minimal M9 medium and rich Luria-Bertani broth (LB). Based on zymograms and protease activity specific assays, it was concluded that the reference strain produced three p...

This study investigated the trait emotional intelligence (trait EI or trait emotional self-efficacy) profiles of 512 students from five university faculties: technical studies, natural sciences, social sciences, arts, and humanities. Using the Trait Emotional Intelligence Questionnaire, it was hypothesised that (a) social sciences would score higher than technical studies in Emotionality, (b) a...

Although efforts to understand the basis for inter-strain phenotypic variation in the most virulent malaria species, Plasmodium falciparum, have benefited from advances in genomic technologies, there have to date been few metabolomic studies of this parasite. Using 1H-NMR spectroscopy, we have compared the metabolite profiles of red blood cells infected with different P. falciparum strains. The...

Agricultural learning repositories can provide new opportunities for sharing, accessing, using and reusing learning resources online. Metadata plays a crucial role in such systems: apart from simply indexing resources, metadata makes it easier to discover a learning resource in a repository, as well as to decide about ways to use it for teaching or learning purposes. In the context of agricultu...

Owing to the information overload we are faced with nowadays, personalization approaches are becoming almost a must, in order to provide relevant information for users. These personalization techniques retrieve results closer to the user interests and preferences, by using the information stored in the user profile. We have carried out a comparative study between six different user profile repr...

There occur a great number of breakdowns in online communities caused by the natural gap between face-to-face and virtual relationships. In addition to this shortcoming, creating, managing and promoting participative online communities is frequently arduous work, and there usually are few tools to help the administrators through this endeavor. So, in this paper we present some results of a rese...

The chemical composition of the watery saliva of hemipteran (both homopteran and heteropteran) insects is crucial for effective feeding, because these insects rely heavily on saliva for extra-oral digestion (Cohen, 1995, 1996, 1998) or detoxification of defensive chemicals (Miles & Oertli, 1993). For phytophagous hemipterans, saliva can also be involved in plant injury. Yet, salivary compositio...
