La mayoría de los adictos a las drogas consume para aumentar su placer sexual

El 72 por ciento de los hombres drogodependientes reconoce haber consumido droga para ser capaces de mantener una relación sexual, y la mayoría de ellos (58%) eligen la cocaína con esta finalidad, siendo ésta la sustancia estupefaciente que más incapacita a nivel sexual, según un estudio realizado por la Universidad de Granada.

El estudio, que analizó la relación entre el consumo de drogas y el funcionamiento sexual mediante una encuesta a 120 drogodependientes, revela que, por el contrario, sólo el 37 por ciento de las mujeres drogodependientes consume alguna droga con este fin, y cuando lo hace, recurre a la cocaína (37%), al speed ball (25%) y al alcohol (25%).

Asimismo, se puede observar que casi el 51 por ciento de los hombres emplean las drogas para mantener una relación sexual, frente al 44 por ciento de mujeres. También se aprecia que los hombres, a la hora de desinhibirse utilizan el alcohol y la cocaína casi en la misma proporción (43 y 37%, respectivamente), mientras que en el caso de las mujeres es el alcohol (72%) la sustancia más empleada.

Para los investigadores del departamento de Personalidad, Evaluación y Tratamiento Psicológico, los profesores Pablo Vallejo Medina, Miguel Pérez García y Juan Carlos Sierra, a la luz de los resultados obtenidos, se produce un hecho paradójico en los hombres, «ya que la cocaína, que es la droga que más emplean como factor potenciador de la sexualidad, es a su vez la droga que más incapacita a nivel sexual».

El estudio se llevó a cabo con 104 varones y 16 mujeres drogodependientes, con edades comprendidas entre los 17 y los 23 años, y fue realizado en colaboración con el Recurso de la Red de Servicios Sociales de la Junta de Andalucía \’Cortijo Buenos Aires\’ de Granada, Proyecto Hombre Granada y la Unidad de Trastornos Emocionales y Adictivos del Hospital Internacional Medimar de Alicante.

Extra virgin olive oil helps to combat breast cancer

Researchers of the Catalonian Institute of Oncology (Spain) and the University of Granada (Spain) have discovered that extra virgin olive oil may help to combat breast cancer, according to a paper published in the last issue of the renowned scientific journal BMC Cancer. The scientists have confirmed the bioactivity of polyphenols (this is, natural antioxidants) present in olive oil in breast cancer cell lines.

The study has proved the anti-HER2 effect of fractions of phenolic compounds directly extracted of extra virgin olive oil in breast cancer cell lines. They have used solid-phase extraction methods of semi-preparative liquid chromatography to isolate fractions of commercial oils and, later, separation techniques (capillary electrophoresis and liquid chromatography connected to mass spectrometry) to check the purity and composition of the fractions.

Such fractions were tested in their anti-cancer capacity both against positive HER2 and negative HER2 breast cancers, using in Vitro models and evaluating the effect of polyphenolic fractions in the expression and activation of HER2 oncoprotein through ELISA specific methods for HER2. Fractions containing polyphonels such as hydroxitirosol, tirosol, elenolic acid, lignans, pinoresinol and acetopinoresinol, and secoiridoids, diacetox oleuropein aglycone, ligustrosid aglycone and oleuropein aglycone were able to induce important tumoricid effects in a range of micromolar and in a selective way against HER2 oncogene.

Proved potentiality

Therefore, this study confirms the potentiality of polyphenols to inhibit HER2 activity and to promote its degradation. Such results, together with the fact that humans have consumed secoiridoids and lignans safely for a long time through oil and olive oil consumption, endorse the fact that such phytochemicals could be an excellent and safe basis for the design of new antiHER2 compounds.

This work has been carried out by Javier A. Menéndez, coordinator of the Translational Research Unit of the Catalonian Institute of Oncology (ICO) in Girona, and by doctors Alberto Fernández Gutiérrez –in charge of the «Research Group of Analytic, Environmental, Biochemical and Food Control»- and Antonio Segura Carretero, member of such group.

This Research Group of the Department of Analytical Chemistry of the University of Granada (Spain) has developed other interesting research works in the characterization of polyphenolic profiles of an important number of plants and metabolomic studies of extracts with proved bioactivity through the use of advanced separation techniques.

Un cambio en la nutrición de las embarazadas libra al feto de patologías

Investigadores de todo el mundo debaten en Granada acerca de los últimos avances sobre la nutrición y el embarazo y apuestan por la intervención en la alimentación de la madre para que el feto no desarrolle las patologías que sufra ella, como diabetes, hipertensión u obesidad.

Según ha explicado a Efe la organizadora del curso «Pregnancy and programming. ENA Granada Winter School» y profesora titular de Pediatría en la Universidad de Granada, Cristina Campoy, se trata de modificar la genética que el feto haya heredado, en función de la patologías maternas.

El encuentro, que se desarrolla hasta el próximo día 13 en Sierra Nevada y reúne a medio centenar de expertos de medicina, biología, bioquímica, farmacia y nutrición de todo el mundo, analizará el impacto de la nutrición desde el embarazo y cómo ésta afecta a la programación de las enfermedades en la vida adulta del feto.

En este sentido, Campoy ha destacado que los hijos de mujeres diabéticas «tienen más posibilidades de sufrir obesidad, hipertensión, síndrome metabólico y otras enfermedades» al tener un aporte de glucosa «muy grande» durante la gestación.

Para evitar esta situación, esta experta recomienda a las futuras madres llegar al embarazo en un grado óptimo de salud y sin deficiencias nutricionales importantes para el desarrollo, como el ácido fólico o la vitamina A.

«Quedarse embarazada no es una situación más que crea muchas expectativas de tipo psicológico y emocional, ya que hay que cuidar mucho la alimentación de nuestras mujeres», ha recordado Campoy.

Por eso, antes de quedarse embarazada, aconseja a las futuras madres que acudan a un especialista que evalúe si nutricionalmente están bien para poder corregir cualquier posible deficiencia y llegar a la gestación en estado de equilibrio.
