PERCEPCIONES DE LOS DÉFICITS DE FUNCIONAMIENTO EJECUTIVO DE ADULTOS CON TDAH VERSUS PERCEPCIONES DE SUS FAMILIARES
2015
Introducción. Los niños con TDAH tienden a sobreestimar su funcionamiento social, conductual y académico, un asunto que ha sido poco investigado en adultos con TDAH. Objetivos. Los objetivos de este trabajo son: 1) Examinar el perfil de funcionamiento ejecutivo de adultos jóvenes con TDAH; 2) Estudiar la relación entre las habilidades de funcionamiento ejecutivo percibidas por adultos con TDAH y sus padres; 3) Comparar las puntuaciones diferenciales (entre las versiones de observador y autoinforme) de adultos con TDAH y adultos con desarrollo típico. Método. Participaron 93 adultos (50 con un diagnóstico de TDAH en la infancia y 43 con desarrollo típico) entre 17 y 24 años. Se aplicaron las…
Partition of Indicaxanthin in Membrane Biomimetic Systems. A Kinetic and Modeling Approach
2009
The solubilization site of indicaxanthin (Ind) in lipid bilayers was investigated by the kinetics of Ind oxidation by peroxyl radicals in water and in aqueous/L-alpha-dipalmitoyl-phosphatidylcholine (DPPC) vesicles, pH 7.4, and 37.0 and 48.0 degrees C, that is, in a gel-like and a crystal liquidlike bilayer state, respectively. The time-dependent Ind absorbance decay, matched with a successful simulation of the reaction kinetic mechanism by Gepasi software, supported a multistep pathway. Computer-assisted analysis allowed calculation of the rate constants associated with the reactions involved, the values of which decreased with increasing DPPC concentration. The binding constant calculated…
The influence of tin compounds on the dynamic properties of liposome membranes: A study using the ESR method
2005
AbstractThe influence of organic and inorganic compounds of tin on the dynamic properties of liposome membranes obtained in the process of dipalmitoylphosphatidylcholine (DPPC) sonication in distilled water was investigated. This was carried out by means of the spin ESR probe method. The probes were selected in such a way as to penetrate different areas of the membrane (a TEMPO probe, 5-DOXYL stearic acid, 16-DOXYL stearic acid). Four compounds of tin were chosen: three organic ones, (CH3)4Sn, (C2H5)4Sn and (C3H7)3SnCl, and one inorganic one, SnCl2. The investigated compounds were added to a liposome dispersion, which was prepared prior to that. The concentration of the admixture was change…
Guidelines for the Direct Detection ofAnaplasmaspp. in Diagnosis and Epidemiological Studies
2017
The genus Anaplasma (Rickettsiales: Anaplasmataceae) comprises obligate intracellular Gram-negative bacteria that are mainly transmitted by ticks, and currently includes six species: Anaplasma bovis, Anaplasma centrale, Anaplasma marginale, Anaplasma phagocytophilum, Anaplasma platys, and Anaplasma ovis. These have long been known as etiological agents of veterinary diseases that affect domestic and wild animals worldwide. A zoonotic role has been recognized for A. phagocytophilum, but other species can also be pathogenic for humans. Anaplasma infections are usually challenging to diagnose, clinically presenting with nonspecific symptoms that vary greatly depending on the agent involved, th…

Estudio ex post-facto del estrés a largo plazo en una muestra de personas adoptadas
2016
In this work we study the impact of relinquishment and the adoption process in posttraumatic symptoms in a group of 55 adults that were adopted as children before 1970. The effects of institutionalization, maltreatment, traumatic revelation of the adopted status and stressful life events have also been studied. No significant differences were found between institutionalized and non-institutionalized adoptees in posttraumatic symptomatology. However, adoptees who suffered maltreatment, traumatic revelation and high level of stressful life events scored significantly higher in intrusion and arousal than those adoptees non-maltreated, without traumatic revelation and with low level of stressfu…
Old sleeping Sicilian beauty: seed germination in the palaeoendemic Petagnaea gussonei (Spreng.) Rauschert (Saniculoideae, Apiaceae).
2015
Petagnaea gussonei (Apiaceae) is a perennial herbaceous species endemic to northeast Sicily (Nebrodi Mountains). It is considered a remnant of the Sicilian Tertiary flora, and is endangered according to the Red List. There is no information in the literature about the germinability of its seeds, even though seed production is know to occur. The aim of this study was to obtain data to better understand seed germination of this species and its biological implications. Thus, several approaches were employed: vitality analyses, gibberellic acid supply, germination and soil microbial flora analyses via end-point and qPCR. The results suggest that seed germination occurs after ca. 1.5 years at a …
Recurrent inoculation: a strategy for a better survival of Pseudomonas fluorescens strain in soil
2022
A growing interest is shown for microbial inoculants as a promising alternative to agrochemicals for sustainable agricultural. However, biotic and abiotic stresses are known to affect their establishment and effectiveness, leading to inconsistent performance in field conditions. At the same time, a poor survival of the strain is often observed, which constitutes a main hamper for bacterial inoculant development. We hypothesize that recurrent inoculations would improve the survival of the strain in soil. For this purpose, we tested different scenarios of inoculation of the plant growth promoting rhizobacteria Pseudomonas fluorescens in soil microcosms: a single inoculation, two inoculations …
The first COVID-19 lockdown reveals an ambivalent relation of French parents with food pleasure: the struggle to find a balance
2021
International audience; In France, a first COVID-19 lockdown took place from March-May 2020. Using an online survey including three open-ended questions, this study explored parents' experiences regarding changes in their family's eating behaviors during this lockdown. French parents (n = 498, 71% mothers) of young children were invited to describe which food-related changes they (1) perceived as positive during the lockdown, (2) perceived as negative, and (3) would like to maintain after the lockdown. A thematic analysis revealed that parents appreciated the choice of more local, fresh and high-quality foods, the time to prepare foods (homemade dishes, new recipes) and cooking and eating w…
