Seroepidemiology of porcine enteric sapovirus in pig farms in Venezuela
2010
Porcine enteric sapovirus (PES) has been shown to cause diarrhea under experimental conditions in gnotobiotic piglets. However, the role of PES as enteric pathogens in porcine farms remains unclear. To further understand the PES-host interactions under field conditions, a serological survey was carried out. To this end the capsid gene of a PES isolate was cloned in the baculovirus expression system and an ELISA was developed based on virus-like particles from the baculovirus-expressed PES capsid protein. A total of 85 serum samples collected from pigs ranging from 8 weeks to over 54 weeks of age were analyzed. An overall seroprevalence to PESs of 62% was found, with significant differences …

CD4+CD25+ regulatory T cells suppress mast cell degranulation and allergic responses through OX40-OX40L interaction.
2008
T regulatory (Treg) cells play a role in the suppression of immune responses, thus serving to induce tolerance and control autoimmunity. Here, we explored whether Treg cells influence the immediate hypersensitivity response of mast cells (MCs). Treg cells directly inhibited the FcεRI-dependent MC degranulation through cell-cell contact involving OX40-OX40L interactions between Treg cells and MCs, respectively. When activated in the presence of Treg cells, MCs showed increased cyclic adenosine monophosphate (cAMP) concentrations and reduced Ca2+ influx, independently of phospholipase C (PLC)-γ2 or Ca2+ release from intracellular stores. Antagonism of cAMP in MCs reversed the inhibitory effec…
ACTIVITIES TO PROMOTE THE SELF-LEARNING OF THE EFFECTIVE COMMUNICATION STUDENT OUTCOME
2018
[EN] Universities all over the world are implementing a competence-based type of teaching and learning to guarantee certain student learning outcomes at the end of the studies. To reach these student outcomes, active methodologies should be included in teaching practice at the same time that carefully designed rubrics might be used for the evaluation of the students. Despite the fact that teachers introduce more and more authentic tasks in the classroom, these activities are not still well employed by all the University teaching staff. The goal of this work is to propose a guideline of activities to promote the self-learning of the effective communication outcome by the students. For that p…
A Guide to Designing a Memory fMRI Paradigm for Pre-surgical Evaluation in Temporal Lobe Epilepsy
2020
There has been increasing interest in the clinical and experimental use of memory functional Magnetic Resonance Imaging (fMRI). The 2017 American Academy of Neurology practice guidelines on the use of pre-surgical cognitive fMRI suggests that verbal memory fMRI could be used to lateralize memory functions in people with Temporal Lobe Epilepsy (TLE) and should be used to predict post-operative verbal memory outcome. There are however technical and methodological considerations, to optimize both the sensitivity and specificity of this imaging modality. Below we discuss these constraints and suggest recommendations to consider when designing a memory fMRI paradigm.
Understanding the limits of self-control: Positive affect moderates the impact of task switching on consecutive self-control performance
2013
Performing consecutive self-control tasks typically leads to deterioration in self-control performance. This effect can be explained within the strength model of self-control or within a cognitive control perspective. Both theoretical frameworks differ in their predictions with regard to the impact of affect and task characteristics on self-control deterioration within a two-task paradigm. Whereas the strength model predicts decrements in self-control performance whenever both tasks require a limited resource, under a cognitive control perspective, decrements should only occur when people switch to a different response conflict in the second task. Moreover, only the cognitive control model …
How trigeminal, taste and aroma perceptions are affected in mint-flavored carbonated beverages
2010
; The integration of olfactory, taste and trigeminal perceptions must be taken into account to better understand the perception of beverages. To do this, seven beverages were formulated to investigate the role of ingredients on trigeminal perception. All mutual interactions between olfactory, gustatory and trigeminal perceptions were studied. Instrumental measurements and sensory evaluation were used to elucidate both physicochemical and sensory interactions. Sensory profiling was conducted according to monadic product presentation, and in vivo aroma release was assessed in the nasal cavities of subjects during beverage consumption. This study further revealed the influence of trigeminal p…
Epidemiology of tattoo skin disease in bottlenose dolphins Tursiops truncatus from the Sado estuary, Portugal
2003
We report on the epidemiology of tattoo disease in a community of bottlenose dolphins Tursiops truncatus from the Sado estuary, Portugal. The presence of tattoos (T++) and tattoo-like (T+) lesions was examined in 586 photographic records of 35 dolphins taken from 1994 to 1997. Images were rated into 3 categories: good (GI), average (AI) and poor (PI). Dolphins positive for T++ lesions were observed in 19 GI. Dolphins with T+ lesions were seen in 39 GI, 23 AI and 6 PI. For statistical analysis the dolphins were divided into 2 age classes (immature and adult) and the data grouped into 2 periods (1994-1995 and 1996-1997). Minimum prevalence of T++ lesions in 32 dolphins was 21.9% in 1994-1995 …
Executive Function Domains among Children with ADHD: Do they Differ between Parents and Teachers Ratings?
2014
Abstract The purpose of this study was to evaluate parents and teachers behavior rating measures of executive functions (EFs) in everyday activities in ADHD children, predominantly inattentive (ADHD-PI) and combined type (ADHD-CT), relative to their typically developing peers. Sixteen children with ADHD combined type and fourteen with ADHD predominantly inattentive type were age- and gender-matched to thirteen typically developing peers. Both parents and teachers of the participants completed the BRIEF. As expected, the executive functioning of children with ADHD were rated significantly worse than those of controls by both parents and teachers. Thus, parent and teachers reported more EF im…
Teacher Perceptions of Reading Motivation in Children with Developmental Dyslexia and Average Readers
2017
Abstract Purpose. This study assessed the teacher perceptions of reading engagement and several components of reading motivation in children with developmental dyslexia and average readers, in an attempt to more clearly understand the role of motivation in developmental dyslexia Method. Sixty-eight children participated in this study. Thirty-three children made up the group with developmental dyslexia and thirty-five made up the group of average readers. In order to assess the reading motivation of the participants, teachers filled two instruments: (a) The Reading Engagement Index ( Wigfield et al., 2008 ), a teacher rating of the engaged reader, and (b) Teacher questionnaire on student mot…
