Competencias argumentativas en la alfabetización académica
2011
Este trabajo se enmarca en las numerosas investigaciones sobre escritura académica que vienen desarrollándose en diversos países. Dentro de ellas, buscamos articular líneas de investigación que se ocupan de la alfabetización académica, de los géneros académicos y del papel de la argumentación en los mismos. Para ello, implementamos desde 2005 un programa de alfabetización académica en una asignatura de Humanidades de una universidad argentina, cuyo tramo final es la elaboración y exposición de ponencias grupales, entendidas como construcciones argumentativas que ponen en consideración resultados de investigación. En relación con éstas, este trabajo presenta resultados, en torno a la relació…

EL PAPEL DE LA AUTOESTIMA EN LA PREVENCIÓN DEL VIH DE JÓVENES ESPAÑOLES

Abstract.THE ROLE OF SELF-ESTEEM IN HIV PREVENTION AMONG SPANISH YOUNG PEOPLE SELF-ESTEEM INFLUENCES ON SEXUAL DEVELOPMENT AND RELATIONSHIPS OF YOUNG PEOPLE.Aims to examine the effects of the self-esteem on HIV prevention, 467 young people from the Valencian Community (Mage = 20.62; SD = 2.14) completed the Rosenberg Self-esteem Scale and the Aids Prevention Questionnaire by Ballester et al. (2007). Results showed statistically significant positive correlation between self-esteem and self-efficacy in condom use (p = .000), perceived competence (p = .041) or number of sexual partners (p = .001). On the other hand, statistically significant negative correlation were found between solidarity t…
Clearing Amyloid-β through PPARγ/ApoE Activation by Genistein is a Treatment of Experimental Alzheimer’s Disease
2016
Amyloid-b (Ab) clearance from brain, which is decreased in Alzheimer's disease, is facilitated by apolipoprotein E (ApoE). ApoE is upregulated by activation of the retinoid X receptor moiety of the RXR/PPAR dimeric receptor. As we have previously demonstrated, estrogenic compounds, such as genistein, have antioxidant activity, which can be evidenced by increased expression of manganese superoxide dismutase (MnSOD). Furthermore, genistein is a non-toxic, well-tested, and inexpensive drug that activates PPARg receptor. We isolated and cultured cortical astrocytes from dissected cerebral cortices of neonatal mice (C57BL/6 J). Preincubation with genistein (5 mM) for 24 hours, prior to the addit…
Tomato sauce enriched with olive oil exerts greater effects on cardiovascular disease risk factors than raw tomato and tomato sauce: a randomized tri…
2016
Epidemiological studies have observed a negative association between tomato intake and the incidence of cardiovascular disease. As tomato sauces are usually cooked with the addition of oil, some studies have pointed out that both processes may increase the bioavailability of the bioactive compounds. However, the effect of consumption of raw tomatoes and tomato sauces on inflammation biomarkers and adhesion molecules related to atherosclerosis remains unknown. The aim of this study was to test the postprandial effects of a single dose of raw tomatoes (RT), tomato sauce (TS) and tomato sauce with refined olive oil (TSOO) on cardiovascular disease risk factors. We performed an open, prospectiv…
Moderate Red Wine Consumption Increases the Expression of Longevity-Associated Genes in Controlled Human Populations and Extends Lifespan in Drosophi…
2021
The beneficial effects of moderate red wine consumption on cardiovascular health are well known. The composition of red wine includes several compounds, such as the phytoestrogen resveratrol, that exert these beneficial effects, although not all the mechanisms by which they act are known. Our aim was to study the effect of red wine consumption on longevity-related genes in controlled human populations, such as cloistered nuns. We found that the expression of catalase, manganese-superoxide dismutase, Sirt1, and p53 was increased in peripheral blood mononuclear cells after 14 days of moderate red wine consumption. This increase was accompanied by an enhanced metabolic wellness: fatty acids, c…
Ethnobotanical uses of wild taxa as galactagogues in Sicily (Italy)
2018
<p>Breastfeeding furnishes optimal nutrition, immune support, and a multitude of health benefits to mothers and newborns. Since ancient times plants have been employed as galactagogues in the folk medicine of many human cultures. In Sicily, a region with great floristic diversity in the Mediterranean area, where a conspicuous pool of species is traditionally used for food and aromatic, cosmetic, handicraft, agricultural, forestry, and medicinal purposes, some people recognize the galactagogue properties of some spontaneous plants.</p><p>The goal of this study was to identify wild plants with galactagogue properties and vegetable-food remedies traditionally used by women du…
ERa dimerization: a key factor for the weak estrogenic activity of an ERa modulator unable to compete with estradiol in binding assays
2016
PMID: 27400858; International audience; AbstractEstrothiazine (ESTZ) is a weak estrogen sharing structural similarities with coumestrol. ESTZ failed to compete with [3H]17β-estradiol ([3H]17β-E2) for binding to the estrogen receptor α (ERα), questioning its ability to interact with the receptor. However, detection by atomic force spectroscopy (AFS) of an ESTZ-induced ERα dimerization has eliminated any remaining doubts. The effect of the compound on the proliferation of ERα-positive and negative breast cancer cells confirmed the requirement of the receptor. The efficiency of ESTZ in MCF-7 cells was weak without any potency to modify the proliferation profile of estradiol and coumestrol. Gro…
Variables psicológicas relacionadas el consumo de drogas en adolescentes : depresión y autoconcepto
2000
Diversos estudios señalan que en entre los factores de riesgo para el inicio del consu¬mo de drogas, que suele darse de forma generalizada en la adolescencia, es posible considerar diversos constructos psicológicos, entre los que destacan el autoconcepto y la depresión. El objetivo principal que guía el presente estudio es conocer el papel que juegan éstos en el consumo de drogas psicoactivas de comercio legal e ilegal. Para ello, se utilizó una muestra de 1570 adolescentes pertenecientes a diferentes centros educativos de la Comunidad de Madrid a través del "Cuestionario de Evaluación del Autoconcepto" (Martorell,Aloy, Gómez y Silva, 1993) y la "Escala de Evaluación de la Depresión" (Del B…
Relaciones entre los recursos y el consumo de alcohol y tabaco en adolescentes
2008
En este trabajo se realiza un análisis de las relaciones entre los recursos de los adolescentes y el consumo de alcohol y tabaco. Los participantes fueron 350 adolescentes mexicanos que cursaban estudios de secundaria, bachillerato o formación profesional. Se utilizó la Escala de Autoconcepto (AF5) el Cuestionario de Valores (VAL), el Cuestionario de Afrontamiento Familiar (CAF), la prueba para identificar Trastornos por el Uso de Alcohol (AUDIT) y el Cuestionario para detectar la Dependencia al Tabaco. Los resultados muestran que las dimensiones de la autoestima, la familiar, la social y la emocional, son las que mejor predicen el consumo de alcohol. Respecto de los valores, la estimulació…
