Protective Effect of Sildenafil against Estradiol-induced ROS production
2010
Several reports suggest that xanthine dehydrogenase (XDH) and its oxidase form (XO) play an important role in various forms of ischemic and vascular injuries. Recently we have demonstrated that 17β-estradiol (E2) induces a significant decrease of the expression and activity of XDH and its conversion to XO in human mammary epithelial cells. E2 is known to induce upregulation of eNOS gene expression in aortic endothelial cells. In light of the ability of XO-derived O2•¯ to combine with •NO to yield ONOO¯, and considering that ONOO¯ converts XDH to XO, it is important to protect tissues against the XO increased activity and ROS increased production, that would in turn react with •NO to augment…
Afferent and efferent connections of the olfactory bulbs in the lizard Podarcis hispanica.
1991
The connections of the olfactory bulbs of Podarcis hispanica were studied by tract-tracing of injected horseradish peroxidase. Restricted injections into the main olfactory bulb (MOB) resulted in bilateral terminallike labeling in the medial part of the anterior olfactory nucleus (AON) and in the rostral septum, lateral cortex, nucleus of the lateral olfactory tract, and ventrolateral amygdaloid nucleus. Bilateral retrograde labeling was found in the rostral lateral cortex and in the medial and dorsolateral AON. Ipsilaterally the dorsal cortex, nucleus of the diagonal band, lateral preoptic area, and dorsolateral amygdala showed labeled cell bodies. Retrogradely labeled cells were also foun…
Microvesicles shed by oligodendroglioma cells and rheumatoid synovial fibroblasts contain aggrecanase activity
2012
Membrane microvesicle shedding is an active process and occurs in viable cells with no signs of apoptosis or necrosis. We report here that microvesicles shed by oligodendroglioma cells contain an ‘aggrecanase’ activity, cleaving aggrecan at sites previously identified as targets for adamalysin metalloproteinases with disintegrin and thrombospondin domains (ADAMTSs). Degradation was inhibited by EDTA, the metalloproteinase inhibitor GM6001 and by tissue inhibitor of metalloproteinases (TIMP)-3, but not by TIMP-1 or TIMP-2. This inhibitor profile indicates that the shed microvesicles contain aggrecanolytic ADAMTS(s) or related TIMP-3-sensitive metalloproteinase(s). The oligodendroglioma cells…
Cine, deporte y propaganda. De "Olympia" al simulacro.
2016
RESUMEN TESIS Este trabajo rastrea y analiza las continuidades entre las herramientas propagandísticas del fascismo y los recursos comunicativos del capitalismo. Se aborda desde la perspectiva del deporte y en el caso concreto del cine olímpico, con una perspectiva histórica de 80 años que trata de elegir los mejores ejemplos del género y los momentos puntuales de cambio. El deporte se considera aquí punto de encuentro entre la política, la historia, la sociedad y la economía y se aborda desde la comunicación, considerando el cine olímpico como ejemplo cerrado, internacional y referencial. Se analiza el relato cinematográfico de los Juegos Olímpicos de Los Ángeles de 1984 (“16 days of glory…

Imatinib compared with interferon and low-dose cytarabine for newly diagnosed chronic-phase chronic myeloid leukemia.
2003
Imatinib, a selective inhibitor of the BCR-ABL tyrosine kinase, produces high response rates in patients with chronic-phase chronic myeloid leukemia (CML) who have had no response to interferon alfa. We compared the efficacy of imatinib with that of interferon alfa combined with low-dose cytarabine in newly diagnosed chronic-phase CML.We randomly assigned 1106 patients to receive imatinib (553 patients) or interferon alfa plus low-dose cytarabine (553 patients). Crossover to the alternative group was allowed if stringent criteria defining treatment failure or intolerance were met. Patients were evaluated for hematologic and cytogenetic responses, toxic effects, and rates of progression.Afte…
A monoamine oxidase B gene variant and short-term antidepressant treatment response.
2007
Genetic differences among patients suffering from Major Depression are likely to contribute to interindividual differences in medication treatment response. Thus, the identification of gene variants affecting drug response is needed in order to be able to predict response to psychopharmacological drugs. This study analyzed a possible association of the common A644G single nucleotide polymorphism (SNP) within intron 13 of the monoamine oxidase B (MAOB) gene with antidepressant treatment response. The study population consisted of n = 102 patients with major depression (criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition; DSM-IV) participating in a randomized do…
The safety and efficacy of dasatinib plus nivolumab in patients with previously treated chronic myeloid leukemia: results from a phase 1b dose-escala…
2021
Although treatment with tyrosine kinase inhibitors (TKIs) has dramatically improved outcomes for the majority of patients with chronic myeloid leukemia (CML), approximately 20–30% will require a ch...
PKP-020 Impact of nadph oxidase functional polymorphisms in acute myeloid leukaemia induction chemotherapy
2016
Background NADPH oxidase, a key mediator of oxidative cardiac damage and remodelling, modulates anthracycline clinical cardiotoxicity. Purpose Single nucleotide polymorphisms (SNPs) of NADPH oxidase genes could lead to interindividual differences in treatment outcome in acute myeloid leukaemia (AML) patients. Material and methods The main three NADPH oxidase polymorphisms (CYBA:rs4673, NCF4:rs1883112 and RAC2:rs13058338) were evaluated in 225 adult patients at the initial diagnosis of AML using a mass spectrometry based multiplex genotyping assay (Sequenom). All patients received induction chemotherapy consisting of idarubicin plus cytarabine (PETHEMA 99, 2007 and 2010 trials). The efficacy…
Cardiovascular Damage Induced by Anti-BCR-ABL TKIs
2018
Anti-BCR-ABL TKIs (tyrosine kinase inhibitors) are drugs that inhibit BCR ABL tyrosine. They are used especially in the treatment of hematological cancer and gastrointestinal stromal tumors (GIST). Anti-BCR-ABL TKIs include first (imatinib), second (nilotinib, dasatinib, bosutinib) and third-generation drugs (ponatinib). Especially second- and third-generation drugs can cause cardiovascular complications such as arterial thrombosis, myocardial ischemia, peripheral arterial diseases, QTc prolongation, and pulmonary hypertension. Nilotinib and ponatinib can cause thrombotic arterial events with various mechanisms. Particularly dasatinib can cause pulmonary hypertension. Compared to convention…
