The ITS1-5.8S-ITS2 Sequence Region in the Musaceae: Structure, Diversity and Use in Molecular Phylogeny

Genes coding for 45S ribosomal RNA are organized in tandem arrays of up to several thousand copies and contain 18S, 5.8S and 26S rRNA units separated by internal transcribed spacers ITS1 and ITS2. While the rRNA units are evolutionary conserved, ITS show high level of interspecific divergence and have been used frequently in genetic diversity and phylogenetic studies. In this work we report on the structure and diversity of the ITS region in 87 representatives of the family Musaceae. We provide the first detailed information on ITS sequence diversity in the genus Musa and describe the presence of more than one type of ITS sequence within individual species. Both Sanger sequencing of amplified ITS regions and whole genome 454 sequencing lead to similar phylogenetic inferences. We show that it is necessary to identify putative pseudogenic ITS sequences, which may have negative effect on phylogenetic reconstruction at lower taxonomic levels. Phylogenetic reconstruction based on ITS sequence showed that the genus Musa is divided into two distinct clades – Callimusa and Australimusa and Eumusa and Rhodochlamys. Most of the intraspecific banana hybrids analyzed contain conserved parental ITS sequences, indicating incomplete concerted evolution of rDNA loci. Independent evolution of parental rDNA in hybrids enables determination of genomic constitution of hybrids using ITS. The observation of only one type of ITS sequence in some of the presumed interspecific hybrid clones warrants further study to confirm their hybrid origin and to unravel processes leading to evolution of their genomes

Videogame-based group therapy to improve self-awareness and social skills after traumatic brain injury

[EN] Background: This study determines the feasibility of different approaches to integrative videogame-based group therapy for improving self-awareness, social skills, and behaviors among traumatic brain injury (TBI) victims and retrieves participant feedback. Methods: Forty-two adult TBI survivors were included in a longitudinal study with a pre- and post-assessments. The experimental intervention involved weekly one-hour sessions conducted over six months. Participants were assessed using the Self-Awareness Deficits Interview (SADI), Patient Competency Rating Scale (PCRS), the Social Skills Scale (SSS), the Frontal Systems Behavior Scale (FrSBe), the System Usability Scale (SUS). Pearson's chi-squared test (χ 2 ) was applied to determine the percentage of participants who had changed their clinical classification in these tests. Feedback of the intervention was collected through the Intrinsic Motivation Inventory (IMI). Results: SADI results showed an improvement in participant perceptions of deficits (χ 2 = 5.25, p < 0.05), of their implications (χ 2 = 4.71, p < 0.05), and of long-term planning (χ 2 = 7.86, p < 0.01). PCRS results confirm these findings (χ 2 = 5.79, p < 0.05). SSS results were also positive with respect to social skills outcomes (χ 2 = 17.52, p < 0.01), and FrSBe results showed behavioral improvements (χ 2 = 34.12, p < 0.01). Participants deemed the system accessible (80.43 ± 8.01 out of 100) and regarded the intervention as interesting and useful (5.74 ± 0.69 out of 7). Conclusions: Integrative videogame-based group therapy can improve self-awareness, social skills, and behaviors among individuals with chronic TBI, and the approach is considered effective and motivating.This study was funded in part by Ministerio de Economia y Competitividad of Spain (Project TEREHA, IDI-20110844; and NeuroVR, TIN2013-44741-R), by Ministerio de Educacion y Ciencia of Spain (Projects Consolider-C, SEJ2006-14301/PSIC; and "CIBER of Physiopathology of Obesity and Nutrition, an initiative of ISCIII"), and by the Excellence Research Program PROMETEO (Generalitat Valenciana.

Self-identified Goals and the Ability to Set Realistic Goals Following Acquired Brain Injury: A Classification Framework

Objective: To develop a framework for classifying the nature of goals identified by people with acquired brain injury (ABI) and explore the extent to which goals and the ability to set realistic goals vary over time and according to stage of recovery

The development of self-awareness and relationship to emotional functioning during early community reintegration after traumatic brain injury

Impaired self-awareness may affect clients' emotional status, engagement in rehabilitation and community reintegration following traumatic brain injury (TBI). The study aimed to investigate the relationship between self-awareness, emotional distress and community integration in adults with TBI during the transition from hospital to the community. Thirty-four rehabilitation clients with TBI were assessed in the week before and 2 months after discharge home. Measures of self-awareness and emotional functioning were administered predischarge and repeated at follow-up along with a measure of community integration. Nonparametric tests were used to compare levels of self-awareness and emotional distress pre- and postdischarge, their interrelationships and association with community integration. Self-awareness significantly increased following discharge, and a trend towards increased depression was found. There were no consistent relationships found between level of self-awareness, emotional functioning, and community integration. The development of self-awareness in the immediate postdischarge phase suggests this is an important time for clinical interventions targeting compensation strategies and adjustment to disability
