The search for novel avenues for the therapy and prevention of Alzheimer's disease.
2006
The prevention and therapy of neurodegenerative disorders in the elderly is one of the greatest challenges facing molecular medicine today. Alzheimer's is an excellent example of a disease being studied by many groups worldwide. Indeed, while many molecular details of this disorder have been elucidated in the last two decades, there are still no strictly causal therapies available. While certain symptomatic pharmacological treatments are frequently employed, current molecular medicine research is focused on central Alzheimer-associated biochemical changes to find the key switch that turns the detrimental Alzheimer process on. Although amyloid beta proteins and tau proteins are the focus of …

Stress effects on cognitive function in healthy adults
2015
In our lives, we are constantly exposed to different sources of stress, specifically psychological or social. Our reaction to stress is an adaptive response due to its role in facilitating survival. However, stress can also have immediate and delayed damaging consequences for health, and it is considered one of the most significant health problems of the 21st century, according to the World Health Organization (2001). The impact of stress extends to most of the physiological systems (i.e. cardiovascular, digestive, immune, neuroendocrine or nervous), resulting in numerous diseases. Cognitive problems stand out among the stress effects related to the nervous system. Given the large impact th…
Differences in Motivation to Engage in Sexual Activity Between People in Monogamous and Non-monogamous Committed Relationships
2021
This study compared motivations to engage in sex between monogamous and non-monogamous respondents (n = 1,238, out of which 641 monogamous and 596 non-monogamous respondents; women—47.4%, men—50.9%, other gender—1.7%; age: M = 27.78 years, SD = 7.53, range = 18–62). The research aim was to identify whether there are differences in self-reported reasons to engage in sexual activity between these two groups. Presented with 17 reasons to engage in sexual activity, the respondents rated the frequency with which they engage in sex for each reason. While both monogamous and non-monogamous respondents reported to engage in sex with the same frequency for the reasons of sexual release and physical …
Ajuste psicosocial en mujeres y personas no binarias queer. Intersecciones entre género y orientación sexual
2023
Las personas con identidades de género y sexuales minoritarias se enfrentan a estresores específicos que pueden poner en riesgo su ajuste psicosocial. Además, el estudio de la interseccionalidad indica que el solapamiento entre estigmatizaciones podría tener un efecto sinérgico en la salud mental y el bienestar de las minorías sexuales. Por ello, es importante estudiar los factores específicos que influyen en el ajuste psicosocial de identidades minoritarias fruto de la intersección entre la identidad sexual y de género, como en las personas no binarias y mujeres queer (lesbianas, bisexuales, pansexuales, asexuales y arrománticas). El objetivo principal de este estudio fue analizar los fact…
Conducta sexual de riesgo en diferentes colectivos: variables implicadas y propuesta de un modelo explicativo
2018
- La infección por VIH representa un gran problema de salud pública y constituye una de las principales causas de mortalidad y discapacidad a nivel mundial con casi 36.7 millones de personas afectadas. Aunque en los primeros años de la epidemia la responsabilidad se atribuyó a determinados colectivos posteriormente se estableció que, aunque algunos subgrupos poseen mayores factores de vulnerabilidad, la conducta sexual de cada individuo constituye la variable que mayor explica la probabilidad infección. En este sentido resulta importante analizar las características diferenciales de ciertos colectivos que, si bien no son completamente homogéneos, comparten ciertas características en relació…

Mapping the actions of prolactin in the brain: sexual dimorphism, steroid regulation and the neuroendocrinology of maternal behaviour
2017
El comportamiento maternal cumple la función de proteger a la descendencia en su periodo de mayor vulnerabilidad y asegurar su supervivencia y bienestar. Esta colección de conductas sociales será expresada por la madre exclusivamente durante el periodo postparto, como resultado de la modulación del sustrato neural responsable de la expresión de la conducta social y reproductiva. Los agentes que llevan a cabo dicha modulación para inducir la expresión del comportamiento maternal incluyen, entre otros, señales endocrinas específicas de la gestación y lactancia. Entre éstas destaca la prolactina, hormona adenohipofisaria estrechamente vinculada con la adaptación del organismo a la maternidad. …
