Gene expression of stem cells at different stages of ontological human development.
2013
Abstract Objectives To compare multipotent mesenchymal stem cells (MSCs) obtained from chorionic villi (CV), amniotic fluid (AF) and placenta, with regard to their phenotype and gene expression, in order to understand if MSCs derived from different extra-embryonic tissues, at different stages of human ontological development, present distinct stemness characteristics. Study design MSCs obtained from 30 samples of CV, 30 of AF and 10 placentas (obtained from elective caesarean sections) were compared. MSCs at second confluence cultures were characterized by immunophenotypic analysis with flow cytometry using FACS CANTO II. The expression of the genes Oct-4 (Octamer-binding transcription fact…

Benevolent and corrective humor, life satisfaction, and broad humor dimensions : extending the nomological network of the BenCor across 25 countries
2020
Indexación: Scopus. Benevolent and corrective humor are two comic styles that have been related to virtue, morality, and character strengths. A previous study also supported the viability of measuring these two styles with the BenCor in 22 countries. The present study extends the previous one by including further countries (a total of 25 countries in 29 samples with N = 7813), by testing the revised BenCor (BenCor-R), and by adding two criterion measures to assess life satisfaction and four broad humor dimensions (social fun/entertaining humor, mockery, humor ineptness, and cognitive/reflective humor). As expected, the BenCor-R showed mostly promising psychometric properties (internal consi…

Give us today our daily bread: The effect of hunger on consumers’ visual attention towards bread and the role of time orientation
2021
Abstract This study investigated the effect of hunger on consumers’ visual attention during a food choice task, and the role of time orientation (i.e., present and future orientation) in this interplay. A lab-based eye-tracking experiment including 102 participants was conducted, with hunger as the manipulated factor (hungry, satiated). Participants in the satiated condition were served a breakfast buffet before the experimental tasks, whereas participants in the hungry condition were served the buffet after completion of the tasks. Both groups were exposed to a set of planograms depicting supermarket shelves and were asked to choose an option they could consider buying, while their eye mov…
Is spectral domain optical coherence tomography useful in improving the contour line with the heidelberg retina tomograph?
2012
Purpose: To compare the measurements of the optic disc in glaucoma patients and glaucoma suspects with spectral domain optical coherence tomography (SD-OCT) and confocal scanning laser ophthalmoscopy (HRT) before and after adjustment of the contour line with the help of the OCT.Methods: In 109 consecutive patients (109 eyes), optic disc parameters were compared prospectively between the 2 devices before and after adjustment of the optic disc area (ODA) on the HRT3 with ODA obtained with the Cirrus SD-OCT as a reference. Intraclass correlation coefficients (ICC) and the 95% limits of agreement (LoA) with Bland-Altman plots were used to compare the agreement of the pre and post-adjustment mea…
A randomized multicenter study comparing seawater washes and carmellose artificial tears eyedrops in the treatment of dry eye syndrome.
2019
Purpose To investigate the safety and efficacy of sterile isotonic seawater washes vs standard treatment with carmellose artificial tears in dry eye syndrome (DES). Patients and methods This is a randomized multicenter prospective study with 12 weeks of follow-up. A group of patients with DES (N=60) were treated with seawater spray (Quinton®) five times daily, and another similar group (N=60) were treated with carmellose artificial tears eyedrops (Viscofresh® 0.5%) five times a day. The parameters studied and measured were as follows: Ocular Surface Disease Index questionnaire score, Schirmer I test (without anesthesia) score, tear osmolarity (TearLab®), tear breakup time, tear meniscus hei…
Development of a Textile Nanocomposite as Naked Eye Indicator of the Exposition to Strong Acids
2017
[EN] Chemical burns, mainly produced by acids, are a topic of concern. A new sensing material for the detection of strong acids able to be incorporated into textiles has been developed. The material is prepared by the covalent attachment of 2,2 ',4,4 ',4 ''-pentamethoxy triphenyl methanol to a mesoporous material which further is included in a nitro resin to obtain a colourless composite. The response of this composite to diverse acid solutions was tested showing the appearance of an intense purple colour (with a colour difference higher than 160) that can be monitored by the naked eye or could be easily digitised to feed an instrumental sensor. Reversibility and resistance to washing cycle…
Production of microalgal external organic matter in a Chlorella-dominated culture: influence of temperature and stress factors
2020
[EN] Although microalgae are recognised to release external organic matter (EOM), little is known about this phenomenon in microalgae cultivation systems, especially on a large scale. A study on the effect of microalgae-stressing factors such as temperature, nutrient limitation and ammonium oxidising bacteria (AOB) competition in EOM production by microalgae was carried out. The results showed non-statistically significant differences in EOM production at constant temperatures of 25, 30 and 35 degrees C. However, when the temperature was raised from 25 to 35 degrees C for 4 h a day, polysaccharide production increased significantly, indicating microalgae stress. Nutrient limitation also see…
