Phenotypic and genotypic evaluation of slime production by conventional and molecular microbiological techniques.
2009
Twenty-nine staphylococcal isolates from different clinical samples were tested for slime production: phenotypic characterization was carried out using Christensen test (tube test) and Congo red agar plate test (CRA plate test), while the presence and expression of icaA and icaD genes were evaluated by real-time PCR. In 79.3% of studied strains there was a concordance between slime production and presence of icaA and icaD genes, and between lack of slime production and absence of both or only one of the tested genes. In four of five strains where positive phenotype was not associated with the presence of ica genes, gene co-expression (evaluated by mRNA determination) was lacking, while in o…

Prostitution voluntary or forced. A contribution to the debate
2011
La tesis abolicionista de que nadie puede elegir libremente vender su cuerpo ha sido cuestionada por quienes reclaman el reconocimiento de derechos laborales para los trabajadores del sexo, lo cual ha dado lugar a una encendida polémica sobre el carácter voluntario o forzado de la prostitución. Los testimonios de veintitrés mujeres (incluyendo cinco ex prostitutas), recogidos mediante entrevistas en profundidad, sugieren que todas ellas están situadas en un punto intermedio del continuum que va desde la coerción criminal hasta la opción vocacional. Los pasajes relativos específicamente al itinerario de acceso a este mundo permiten distinguir tres tipos de prostitución en función del grado d…
Vascular Microarchitecture of Murine Colitis-Associated Lymphoid Angiogenesis
2009
In permissive tissues, such as the gut and synovium, chronic inflammation can result in the ectopic development of anatomic structures that resemble lymph nodes. These inflammation-induced structures, termed lymphoid neogenesis or tertiary lymphoid organs, may reflect differential stromal responsiveness to the process of lymphoid neogenesis. To investigate the structural reorganization of the microcirculation involved in colonic lymphoid neogenesis, we studied a murine model of dextran sodium sulfate (DSS)-induced colitis. Standard 2-dimensional histology demonstrated both submucosal and intramucosal lymphoid structures in DSS-induced colitis. A spatial frequency analysis of serial histolog…
Shelf life assessment of industrial durum wheat bread as a function of packaging system
2017
This study compared the effect of different packaging systems on industrial durum wheat bread shelf-life, with regard to thermoformed packaging (TF) and flow-packaging (FP). Two TFs having different thickness and one FP were compared by assessing physico-chemical and sensorial properties and volatile compounds of sliced bread during 90 days of storage. Texture, aw and bread moisture varied according to a first-order kinetic model, with FP samples ageing faster than TFs. Sensorial features such as consistency, stale odor, and sour odor, increased their intensity during storage. Furans decreased, whereas hexanal increased. The Principal Component Analysis of the whole dataset pointed out that…
Impact of work aspects on communication, emotional intelligence and empathy in nursing
2019
ABSTRACT Objective: to assess the impact of the type of contract and seniority of nursing staff on their attitudes towards communication, emotional intelligence and empathy. Methods: the instruments measuring attitudes towards communication, empathy and emotional intelligence. The study sample was composed of 450 nurses from 7 hospitals. To explore the effect of the variables studied, one-factor ANOVA test, Pearson correlations and hierarchical multiple linear regression models were performed according to the type of contract. Results: there are statistically significant differences between the variables studied according to the type of contract. More specifically, the nursing staff with pe…
Variation and change in English resultative constructions
2010
AbstractThe system of English resultative constructions is in a state of flux characterized by variation between two of its most prominent competitors,way-constructions as inShe worked herwayto the topand reflexive structures as inShe worked herselfto the top.Although this competition has occasionally been addressed in the literature (cf. Jackendoff, 1990:213; Kirchner, 1951:158; Salkoff, 1988:54ff.), the present findings reveal that the long-standing rivalry between these structures has resulted in an increased use of theway-construction at the expense of reflexive structures. In addition, the coexistence ofway-constructions with semantically overlapping reflexive structures eventually cul…

A Bayesian unified framework for risk estimation and cluster identification in small area health data analysis.
2020
Many statistical models have been proposed to analyse small area disease data with the aim of describing spatial variation in disease risk. In this paper, we propose a Bayesian hierarchical model that simultaneously allows for risk estimation and cluster identification. Our model formulation assumes that there is an unknown number of risk classes and small areas are assigned to a risk class by means of independent allocation variables. Therefore, areas within each cluster are assumed to share a common risk but they may be geographically separated. The posterior distribution of the parameter representing the number of risk classes is estimated using a novel procedure that combines its prior …
Evaluation of Occupational Training Programs for women
2006
This paper summarizes the results obtained from the evaluation of Occupational Training Programs through which we checked the quality of service and the efficiency of the introduction of women into the labour market, as well as the need to promote quality Occupational Training specifically for women that will not only facilitate their introduction into the labour market by adapting their personal skills to its needs, but will also encourage personal and social improvement.
