Atresia anal en el perro y el gato

Ponencia en el XXXI CONGRESO NACIONAL DE LA ASOCIACIÓN MEXICANA DE MÉDICOS VETERINARIOS ESPECIALISTAS EN PEQUEÑAS ESPECIES, A.C.La atresia anal es una patología poco frecuente con una prevalencia del 0.13% y del 1.6% para el caso de los perros y de los gatos menores de un año de edad respectivamente, atendidos en nuestro centro hospitalario. En el presente documento se expone la experiencia en el diagnóstico y manejo de tres pacientes con atresia anal, realizamos una revisión de las teorías de los mecanismos fisiopatológicos involucrados en el desarrollo embrionario, y con base en esos criterios, sugerimos la mejor clasificación del tipo de atresia anal partiendo del análisis de las propuestas existentes y su relación con los conceptos actuales de la anatomía embriológica

The complex HLA-E-nonapeptide in Behçet disease

HLA-B, mainly HLA-B51, and HLA-A molecules are associated with disease, but the ultimate cause of this association remains obscure. There is evidence that NK cells participate in the etiopathology of BD. NK cells have activator and inhibitor surface receptors, like the KIR and the NKG2 families. Classical HLA-class I molecules (A, B and C) are keys in the activity control of the NK because they are KIR ligands. Most NKG2 receptors bind HLA-E, which presents only nonapeptides derived from the signal peptide of other class-I molecules. Objective: This study investigates the contribution of the pair HLA-E and ligand, nonapeptide derived from the 3-11 sequence of the signal peptides of class I classical molecules, to the susceptibility to BD. Methods: We analyzed the frequency of the HLA-derivated nonapeptide forms in 466 BD patients and 444 controls and an HLA-E functional dimorphism in a subgroup of patients and controls. Results: In B51 negative patients, the frequency of VMAPRTLLL was lower (70.4% versus 80.0% in controls; P=0.006, Pc=0.04, OR=0.60, 95%CI 0.41-0.86), and the frequency of VMAPRTLVL was higher (81.6% versus 71.4% in controls; P=0.004, Pc=0.03, OR=1.78, 95%CI 1.20-2.63). In homozygosity, VMAPRTLLL is protective, and VMAPRTLVL confers risk. The heterozygous condition is neutral. There were no significant differences in the distribution of the HLA-E dimorphism. Discussion: Our results explain the association of BD with diverse HLA-A molecules, reinforce the hypothesis of the involvement of the NK cells in the disease and do not suggest a significant contribution of the HLA-E polymorphism to disease susceptibility.This work was supported by Fondo de Investigaciones Sanitarias, Instituto de Salud Carlos III (ISCIII PI16/01373 and PI19/00605), Fondos FEDER and Plan Andaluz de Investigación (CTS-0197)

Portuguese validation of the Adult Separation Anxiety-Questionnaire (ASA-27)

Adult separation anxiety disorder (ASAD) is characterized by developmentally inappropriate and excessive fear or anxiety concerning separation from those to whom the individual is attached. Despite the high rates of this diagnosis among Portuguese adults, there is a lack of measures to assess it. In this study, we assessed the psychometric properties of a Portuguese adaptation of the Adult Separation Anxiety questionnaire (ASA-27) on a sample of 267 adults (72.7% women) aged 18-80 years (M = 40.5, SD = 13.1). Factor structure, internal consistency, and convergence validity were examined. This study confirmed the single-factor structure of the Portuguese version of ASA-27. Consistency was high for the total sample (ω = .92) and by gender (ω = .93 and 92, men and women groups, respectively). The scale was positively related to the Portuguese version of State-Trait Anxiety Inventory (STAI) (r = .57, p< .001, for both State and trait anxiety scales) and Composite Codependency Scale total score (r = .29, p< .001). In addition, the ASA-27 total score showed incremental validity in the explanation of anxiety measured by STAI. In conclusion, results show that the Portuguese version of the ASA-27 is a reliable and valid measure of ASAD

Benthic community recovery from brine impact after the implementation of mitigation measures

In many regions, seawater desalination is a growing industry that has its impact on benthic communities. This study analyses the effect on benthic communities of a mitigation measure applied to a brine discharge, using polychaete assemblages as indicator. An eight-year study was conducted at San Pedro del Pinatar (SE Spain) establishing a grid of 12 sites at a depth range of 29–38 m during autumn. Brine discharge started in 2006 and produced a significant decrease in abundance, richness and diversity of polychaete families at the location closest to the discharge, where salinity reached 49. In 2010, a diffuser was deployed at the end of the pipeline in order to increase the mixing, to reduce the impact on benthic communities. After implementation of this mitigation measure, the salinity measured close to discharge was less than 38.5 and a significant recovery in polychaete richness and diversity was detected, to levels similar to those before the discharge. A less evident recovery in abundance was also observed, probably due to different recovery rates of polychaete families. Some families like Paraonidae and Magelonidae were more tolerant to this impact. Others like Syllidae and Capitellidae recovered quickly, although still affected by the discharge, while some families such as Sabellidae and Cirratulidae appeared to recover more slowly.These surveys were funded by the Mancomunidad de Canales del Taibilla

Desarrollo de prácticas de Ciencias del Mar con alumnos de secundaria

La docencia en ciencias en la enseñanza secundaria requiere de experiencias prácticas en el laboratorio o en el campo que permitan desarrollar los contenidos de las materias. El fomento de la vocación científica es el objetivo del programa “Ven a hacer prácticas a la universidad” promovido por la Facultad de Ciencias de la Universidad de Alicante. Esta actividad está dirigida a alumnado de niveles comprendidos entre 4º de ESO y 2º de Bachiller y consiste en la realización de prácticas de laboratorio en los Departamentos de la Facultad de Ciencias. En este trabajo se analiza la participación del Departamento de Ciencias del Mar y Biología Aplicada en dicho programa durante el desarrollo de dos prácticas de laboratorio. El análisis de las encuestas realizadas tanto para el alumnado como para el profesorado participante, permite evaluar las prácticas en los contenidos, el nivel docente, y el grado de satisfacción de ambos colectivos. El desarrollo de este tipo de experiencias permite completar la formación científica en la enseñanza secundaria, y servir de vínculo con la universidad, promoviendo la vocación de futuros científicos y facilitando una posible futura incorporación de los estudiantes a los estudios superiores
