GDNF is a potent neurotrophic factor that protects catecholaminergic neurons from toxic damage and induces fiber outgrowth. However, the actual role of endogenous GDNF in the normal adult brain is unknown, even though GDNF-based therapies are considered promising for neurodegenerative disorders. We have generated a conditional GDNF-null mouse to suppress(More)
The carotid body (CB) is a neural crest-derived organ whose function is to elicit hyperventilation in response to hypoxemia. The CB contains clusters of neuron-like glomus cells enveloped by glia-like sustentacular cells. CB responsiveness to acute hypoxia relies on the inhibition of O2-sensitive K+ channels in glomus cells, which leads to depolarization,(More)
Hemeoxygenase-2 (HO-2) is an antioxidant enzyme that can modulate recombinant maxi-K(+) channels and has been proposed to be the acute O(2) sensor in the carotid body (CB). We have tested the physiological contribution of this enzyme to O(2) sensing using HO-2 null mice. HO-2 deficiency leads to a CB phenotype characterized by organ growth and alteration in(More)
Early adaptive responses to hypoxia are essential for cell survival, but their nature and underlying mechanisms are poorly known. We have studied the post-transcriptional changes in the proteome of mammalian cells elicited by acute hypoxia and found that phosphorylation of eukaryotic elongation factor 2 (eEF2), a ribosomal translocase whose phosphorylation(More)
Electronic publishing has transformed the business model of publishing houses in Spain in such a way that two models currently co-exist. There are, on the one hand, traditional publishers of mostly paper-based volumes, whose business models are based on having large catalogues of titles and large print-runs, though print-runs are increasingly smaller and(More)
Neurotrophic factors are small proteins necessary for neuron survival and maintenance of phenotype. They are considered as promising therapeutic tools for neurodegenerative diseases. The glial cell line-derived neurotrophic factor (GDNF) protects catecholaminergic cells from toxic insults; thus, its potential therapeutic applicability in Parkinson's disease(More)
Libraries specialisingin health sciences, located in hospitals and health centres are defined as being within the fields of biomedicine, nursing and physiotherapy. They are called hospital libraries and their mission is directed at users who need information for clinical practice, teaching and research. Recently, the concept of information literacy has been(More)
