Endocytosis constitutes an essential process in the regulation of the expression of cell surface molecules and receptors and, therefore, could participate in the neural-glial interactions occurring during brain development. However, the relationship between endocytic pathways in astroglial cells under physiological and pathological conditions remains poorly(More)
The morphology and subcellular positioning of the Golgi complex depend on both microtubule and actin cytoskeletons. In contrast to microtubules, the role of actin cytoskeleton in the secretory pathway in mammalian cells has not been clearly established. Using cytochalasin D, we have previously shown that microfilaments are not involved in the endoplasmic(More)
Ethanol induces severe alterations in membrane trafficking in hepatocytes and astrocytes, the molecular basis of which is unclear. One of the main candidates is the cytoskeleton and the molecular components that regulate its organization and dynamics. Here, we examine the effect of chronic exposure to ethanol on the organization and dynamics of actin and(More)
We have previously reported that actin filaments are involved in protein transport from the Golgi complex to the endoplasmic reticulum. Here we examined whether myosin motors or actin comets mediate this transport. To address this issue we have used, on one hand, a combination of specific inhibitors such as BDM (2,3-butanedione monoxime) and ML7(More)

In this paper we measure the welfare cost of fluctuations in a simple representative agent economy with nonclearing markets. The market friction we consider involves price rigidities and a voluntary exchange rationing scheme. These features are incorporated into an otherwise standard neoclassical growth model. We show that the frictions we introduce make(More)
Strategies designed to reduce adiposity and cardiovascular-accompanying manifestations have been based on nutritional interventions conjointly with physical activity programs. The aim of this 13-week study was to investigate the putative benefits associated to hypoxia plus exercise on weight loss and relevant metabolic and cardiorespiratory variables, when(More)
The kidney synthesizes L-carnitine and reabsorbs it via the Na(+)/L-carnitine cotransporter OCTN2. This study investigates the ontogeny of OCTN2, gamma-trimethylaminobutyraldehyde dehydrogenase (TMABA-DH) and gamma-butyrobetaine hydroxylase (BBH) in rat kidneys. Foetuses, newborn, suckling, weaning and adult rats were used. The apical membranes of foetal(More)
The interest in having traceability systems covering all the stages of the intermodal logistic chain at the trading partners disposal has increased in the recent years, in order to reduce business risks, achieve greater efficiency, support product safety, and provide information to consumers and partners. In this paper we address the subject of managing(More)

In the most recent issue, I announced that I will quit my editorship and I asked for possible successors. I am pleased to announce that Re-nató Alvarez-Nodarse, Universidad Carlos III de Madrid, jointly with Rafael J. Yáñez, Universidad de Granada, have agreed to succeed me as editors. Both will already co-edit the next two issues with me. So you are(More)
