Poás volcano: Geophysical-Geochemical signatures and dynamics of its magmatic-hydrothermal system
(International Association of Volcanology and Chemistry of the Earth's Interior, 2014-09)
Poás volcanic complex hosts a hyper-acid lake where geochemical signatures are related to two major controlling processes: (a) The level of inux and dissolution-hydrolysis of magmatic volatiles in a sub-surface hydrothermal ...
Expression of neuronal nitric oxide synthase in the hippocampal formation in affective disorders
(Associação Brasileira de Divulgação Científica, 2008)
Hippocampal output is increased in affective disorders and is mediated by increased glutamatergic input via N-methyl-D-aspartate (NMDA) receptor and moderated by antidepressant treatment. Activation of NMDA receptors by ...
HLA-G Expression in the Skin of Patients with Systemic Sclerosis
(J RHEUMATOL PUBL CO, 2009)
Objective. To determine HLA-G expression in skin biopsies from patients with systemic sclerosis (SSc), and its association with epidemiological, clinical, and laboratory variables and survival. Methods. Paraffin-embedded ...
Characterization and in vitro activities of cell-free antigens from Histoplasma capsulatum-loaded biodegradable microspheres
(ELSEVIER SCIENCE BV, 2009)
In the last decades, the incidence of histoplasmosis, a pulmonary fungal disease caused by Histoplasma capsulatum, has increased worldwide. In this context, vaccines for the prevention of this infection or therapies are ...
Experimental Chemotherapy in Paracoccidioidomycosis Using Ruthenium NO Donor
(SPRINGER, 2011)
Paracoccidioidomycosis (PCM) is a granulomatous disease caused by a dimorphic fungus, Paracoccidioides brasiliensis (Pb). To determine the influence of nitric oxide (NO) on this disease, we tested cis-[Ru(bpy)2(NO)SO3](PF6), ...
Lateral Parabrachial Afferent Areas and Serotonin Mechanisms Activated by Volume Expansion
(WILEY-LISS, 2008)
Recent evidence has shown that the serotonergic mechanism of the lateral parabrachial nucleus (LPBN) participates in the regulation of renal and hormonal responses to isotonic blood volume expansion (BVE). We investigated ...
Aquaporin 2 expression increased by glucagon in normal rat inner medullary collecting ducts
(AMER PHYSIOLOGICAL SOC, 2009)
Yano Y, Cesar KR, Araujo M, Rodrigues Jr. AC, Andrade LC, Magaldi AJ. Aquaporin 2 expression increased by glucagon in normal rat inner medullary collecting ducts. Am J Physiol Renal Physiol 296: F54-F59, 2009. First published ...
Inducible nitric oxide synthase-deficient mice show exacerbated inflammatory process and high production of both Th1 and Th2 cytokines during paracoccidioidomycosis
(ELSEVIER SCIENCE BV, 2009)
Paracoccidioidomycosis, the major systemic mycosis in Latin America, is caused by fungus Paracoccidioides brasiliensis. To analyze the influence of inducible nitric oxide synthase (iNOS) in this disease, iNOS-deficient ...
Endodontic Chelators Induce Nitric Oxide Expression by Murine-cultured Macrophages
(ELSEVIER SCIENCE INC, 2009)
Introduction: Endodontic chelators may extrude to apical tissues during instrumentation activating cellular events on periapical tissues. This study assessed in vitro the expression of nitric oxide (NO) concentrations by ...
TLR4/MYD88-dependent, LPS-induced synthesis of PGE(2) by macrophages or dendritic cells prevents anti-CD3-mediated CD95L upregulation in T cells
(NATURE PUBLISHING GROUP, 2008)
Antigen-presenting cells (APCs) control T-cell responses by multiple mechanisms, including the expression of co-stimulatory molecules and the production of cytokines and other mediators that control T-cell proliferation, ...
