Determinantes de la intención del consumidor de ir a un destino turístico. Aplicación al caso de "Mundo Maya-México"

[ES] Cada destino turístico tiene una marca que puede elegir el consumidor a la hora de viajar. Este trabajo examina, a través de un modelo causal que contrastamos empíricamente para el caso de Mundo Maya-México, el papel que desempeña la reputación, las emociones y la confianza en la intención de compra de los consumidores de un destino turístico.

Human LDL Structural Diversity Studied by IR Spectroscopy

Lipoproteins are responsible for cholesterol traffic in humans. Low density lipoprotein (LDL) delivers cholesterol from liver to peripheral tissues. A misleading delivery can lead to the formation of atherosclerotic plaques. LDL has a single protein, apoB-100, that binds to a specific receptor. It is known that the failure associated with a deficient protein-receptor binding leads to plaque formation. ApoB-100 is a large single lipid-associated polypeptide difficulting the study of its structure. IR spectroscopy is a technique suitable to follow the different conformational changes produced in apoB-100 because it is not affected by the size of the protein or the turbidity of the sample. We have analyzed LDL spectra of different individuals and shown that, even if there are not big structural changes, a different pattern in the intensity of the band located around 1617 cm 21 related with strands embedded in the lipid monolayer, can be associated with a different conformational rearrangement that could affect to a protein interacting region with the receptor.
