INTRODUCTION Osteoarthritis (OA) is characterized by altered homeostasis of joint cartilage and bone, whose functional properties rely on chondrocytes and osteoblasts, belonging to mesenchymal stem cells (MSCs). WNT signaling acts as a hub integrating and crosstalking with other signaling pathways leading to the regulation of MSC functions. The aim of this(More)
The results of administering the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A) of Shor and E. Orne (1962) to a Spanish sample are on the whole consistent with those results obtained in other normative studies, especially Bongartz's work with a German sample, and they confirm HGSHS:A's usefulness in non-Anglophone countries. The Spanish(More)
BACKGROUND Human endogenous retroviruses (HERVs) are genomic sequences that resulted from ancestral germ-line infections by exogenous retroviruses and therefore are transmitted in a Mendelian fashion. Increased HERV expression and antibodies to HERV antigens have been found in various autoimmune diseases. HERV-K18 in chromosome 1 was previously associated(More)
BACKGROUND Selenoprotein S (SelS) protects the functional integrity of the endoplasmic reticulum against the deleterious effects of metabolic stress. SEPS1/SelS polymorphisms have been involved in the increased release of pro-inflammatory cytokines interleukin (IL)-1beta, tumor necrosis factor (TNF)-alpha and IL-6 in macrophages. We aimed at investigating(More)
BACKGROUND The aim of this study was to evaluate, the existence of a signature of differentially expressed microRNAs (miRNAs) during osteogenic differentiation of bone marrow MSCs from OA and healthy donors and to describe their possible implication in joint regeneration through modulation of molecular mechanisms involved in homeostatic control in OA(More)
The study of changes in ERPs provoked by negative hypnotic hallucinations has thus far yielded contradictory results. Most previous studies have failed to separate specific changes in the processing of the hallucinated stimuli from non-specific changes in arousal due to hypnosis. The present study addresses this issue with the combination of two(More)
