El cerebro requiere un elevado consumo de energía que obtiene mediante la fosforilación oxidativa mitocondrial. Esto hace del cerebro un órgano muy vulnerable a la hipoxia. Millones de ciudadanos que normalmente viven en ...
In marine teleosts that spawn pelagic eggs (pelagophils), the process of oocyte hydration that occurs during meiosis resumption is a key physiological process for the survival of the eggs in the ocean. Previous studies ...
The aim of the present thesis is directed towards the comprehension of the mechanisms involved in the regulation of lipid and carbohydrate metabolism in relevant species in European aquaculture. Special attention has been ...
En la tesis presentada se pretendió de desarrollar nuevas herramientas para investigar los efectos de contaminantes ambientales sobre organismos acuáticos. Por esto se eligió el mejillón cebra como organismo centinela del ...
The aim of this work is to gain insight in the understanding of the biogenesis of membrane proteins, specially their folding, assembly and ER-exit. Our model is the human cystinuria transporter rBAT- b0,+AT. Disulfides and ...
Liver X receptors (LXRs) son miembros de la superfamilia de receptores nucleares que ejercen un papel clave en la homeaostasis lipídica y en la regulación negativa de la inflamación. Los macrófagos tienen funciones esenciales ...
Els estudis que composen aquesta tesi tenen com a objectiu optimitzar el creixement muscular i reduir l'acumulació de greix en dues espècies d'aqüicultura, l’orada i la truita irisada. Primerament, es van identificar i ...
Stable isotopes, as tracers of the food chain, have been used to characterize the relationship between consumers and their food since isotopic fractionation implies discrimination against certain isotopes. But stable isotope ...
Se plantea la siguiente hipótesis de trabajo que: 1) El entrenamiento de fuerza realizado en condiciones de hipoxia mejora el rendimiento anaeróbico específico. 2) Las condiciones de hipoxia simulada no provocan un descenso ...
La panerola Blattella germanica és un insecte de metamorfosi incompleta (hemimetàbol) i anautògen. Aquesta és una estratègia reproductiva per la qual les femelles no es poden reproduir fins que no han menjat. D'alguna ...
En la actualidad existe una gran evidencia científica sobre los múltiples beneficios que ofrecen la actividad física y el ejercicio físico en la promoción y mantenimiento de la salud. Los diferentes estudios han mostrado ...
Nuclear receptor LXR is a ligand dependent transcription factor. The activating ligands of LXR are specific oxidized forms of cholesterol (oxysterols) and intermediate products of the cholesterol biosynthetic pathway. This ...
The Extracellular Matrix (ECM) is a complex network secreted by cells that serves as a structural element in tissues and also influences their development and physiology. More specifically, the extracellular matrix helps ...
The aim of this thesis was to study the function and regulation of two of the major players in the carbohydrate metabolism regulated by insulin, the facilitative glucose transporters GLUT2 and GLUT4, in teleost fish. In ...
La modalidad de trabajo a gran altitud en Chile denominada hipobaria intermitente crónica a gran altitud abarca tanto la explotación de la gran minería, como la actividad de los grandes centros astronómicos, puestos ...
Trex1 is an exonuclease that was first identified in mammal cells and due to its role in DNA metabolism was conjectured to have a role in DNA damage repair and cancer. It was unexpected to find that Trex1-/- mice generated ...
Aicardi-Goutières Syndrome (AGS) is a rare encephalopathy which mimics a viral intrauterine infection and is characterized by calcifications of the basal ganglia, cerebral atrophy and IFN-a in the cerebrospinal fluid. AGS ...
Cancer immunotherapy represents a treatment strategy which is being clinically tested to complement surgery, radiotherapy and chemotherapy – the current cornerstones of our fight against cancer. It has become clear now, ...
