Variables biopsicosociales que contribuyen al diferente impacto de la violencia de pareja en la salud de las mujeres: factores de vulnerabilidad y re…
2015
La violencia de pareja es un fenómeno que sigue estando de actualidad, habiendo proliferado en las últimas décadas las investigaciones en relación con las consecuencias que este tipo de violencia produce en la salud, tanto física como mental, de estas mujeres. Sin embargo, han sido menos frecuentes los estudios realizados acerca de la influencia que los factores personales, biológicos o sociales ejercen sobre el diferente impacto producido en el estado clínico de las mujeres. Objetivos: El principal objetivo de esta Tesis Doctoral fue determinar qué variables biopsicosociales estaban influyendo en las diferencias individuales presentadas por las mujeres víctimas de violencia de pareja en el…
Respuesta emocional de ira y alteraciones del lenguaje en pacientes con esquizofrenia
2015
Los pacientes con esquizofrenia presentan alteraciones en el procesamiento emocional especialmente en la expresión, y en el reconocimiento de emociones. Sin embargo, se ha investigado poco cómo experimentan las emociones los pacientes con esquizofrenia y en concreto existe una literatura muy escasa sobre la respuesta cardiovascular, hormonal o de la activación asimétrica cerebral. Por otro lado, la ira es clave en la conducta agresiva, y en el caso de la esquizofrenia parece estar mediada por síntomas psicóticos como las alucinaciones y los delirios. Basándonos, pues, en la respuesta emocional anómala que pueden presentar las personas con esquizofrenia en general, y los pacientes con alucin…
Elevated cortisol modulates hsp70 and hsp90 gene expression and protein in sea bass head kidney and isolated leukocytes
2012
In fish, interactions between Hsps and cortisol are involved in stress modulated physiological processes including innate immune responses. Cortisol exerts a role in the regulation of Hsps synthesis. Fish head kidney is a lymphomieloid and endocrine organ releasing cortisol, and it is the central organ for immune-endocrine interactions. In sea bass, cortisol intraperitoneal injection and in vitro treatment of head kidney cells show that inducible Hsp70 and Hsp90 are modulated by this hormone. However, an inverse relationship between mRNA expression (real-time PCR) and Hsp70 and Hsp90 protein levels (densitometric band analysis) was found. Time-course assays indicate a cortisol-mediated regu…
Acute responses of comprehensive gonadosteroids and corticosteroids to resistance exercise before and after 10 weeks of supervised strength training
2020
Resistance training is a potent stimulus for muscle growth and steroid hormones are known to play a role in this adaptation. However, very little is known about the acute exercise‐induced gonadosteroid and corticosteroid hormone responses, including key smaller‐concentration intermediate hormones. The present study determined the acute responses of these steroid hormone families using quantitative UHPLC mass spectrometry (MS) following resistance exercise in strength‐trained men. Venous and fingertip blood was drawn pre‐, mid‐, 5 min post‐ and 15 min post‐resistance exercise, both before and after 10 weeks of supervised resistance training. The experimental resistance exercise sessions cons…

Acute neuromuscular and endocrine responses and recovery to single session combined endurance and strength loadings: ‘Order effect’ in untrained youn…
2013
The purpose of this study was to investigate acute neuromuscular and endocrine responses and recovery to a single session of combined endurance and strength loading using two loading orders. Forty-two men were demographically matched to perform a single session of combined endurance+strength (E+S) or strength+endurance (S+E) loading. The strength loading was conducted on a leg press and included sets of power, maximal strength and hypertrophic loads with an overall duration of 30 minutes. The endurance loading was conducted on a bike ergometer and performed by continuous cycling over 30min at 65% of subject’s individual maximal Watts. Both loading conditions led to significant acute reducti…
Recovery of rescuers from a 24-hour shift and its association with physical fitness
2013
The work of rescuers can be physically and psychologically very demanding so it is important for them to have sufficient recovery between work shifts. The purpose of this thesis was to study recovery of rescuers and to see if physical fitness is associated with recovery from work shifts. Heart rate variability (HRV) recordings reflect changes in the autonomic nervous system, and they were used for the analysis of stress and recovery. HRV was recorded for 96 hours, from the beginning of a 24-hour work shift to the beginning of the next shift. Physical fitness assessment included VO2max estimation with a submaximal bicycle ergometer test, and maximal strength testing (isometric bench press an…
Assessing Stress Resilience After Smolt Transportation by Waterborne Cortisol and Feeding Behavior in a Commercial Atlantic Salmon (Salmo salar) Grow…
2022
Sampling protocols and water quality sensors have been developed to assess fish health and welfare in recirculating aquaculture systems (RASs). Still, the use of fish-based non-invasive welfare indicators, reflecting the physiological state of the fish, is limited in this type of system. Cortisol, the major stress-coping hormone in fish, diffuses through the gills. Consequently, waterborne cortisol is a potential fish-based non-invasive welfare indicator in RAS. However, its use in commercial rearing systems is sparse. In this study, we evaluated water cortisol levels and feeding behavior as welfare indicators of newly inserted smolt in a commercial RAS for harvest size Atlantic salmon. The…
The relationship between the levels of salivary cortisol and the presence of xerostomia in menopausal women. A preliminary study.
2006
La xerostomía es un síntoma especialmente frecuente en las mujeres en torno a la menopausia, que se asocia en muchas ocasiones con estados depresivos. Objetivos: Valorar la relación entre las cifras del flujo salival total no estimulado y la presencia de xerostomía, y determinar los niveles de cortisol salival y su relación con la misma. Diseño del estudio: Se seleccionaron 30 mujeres de los pacientes que acuden al Departamento de Medicina y Cirugía Bucofacial y se formaron dos grupos, estudio y control. Se recogieron muestras de flujo salival total no estimulado y mediante técnica de ELISA se determinaron las cifras de cortisol salival. Resultados: Las medias de flujo salival total no esti…
The Role of Spatial Exploration and Territoriality in Establishing Gilthead Seabream (Sparus aurata) Hierarchies, and Their Effects upon Underlying S…
2023
Territoriality, spatial exploration and social hierarchy are strictly related behaviors in gregarious fishes, and are often under-appreciated in farms where the individuals are confined within crowded spaces. In this study, we investigated the role of spatial exploration, elucidating the importance of time upon forming the social organization, and the role of the territoriality in gilthead seabream (Sparus aurata), using two experimental approaches. In the first approach, three fish were placed sequentially in the aquarium with an interval of two days (sequential model), while in the second (simultaneous model), two fish were simultaneously placed in an aquarium divided by a barrier which w…
