BACKGROUND CO2 vasodilates and O2 vasoconstricts the cerebral vascular bed; the opposite is true in the lungs. When the brain and lungs are connected exclusively in series, which feedback loop predominates is unknown. The circulation of the superior cavopulmonary connection (SCPC) provides a unique physiology to answer this question. METHODS AND RESULTS To determine cerebral and pulmonary blo...
BACKGROUND Systemic-to-pulmonary collateral flow (SPCF) is common in single-ventricle patients with superior cavopulmonary connections (SCPC). Because no validated method to quantify that SPCF exists, neither its hemodynamic burden nor its clinical impact can be systematically evaluated. We hypothesize that (1) the difference in total ascending aortic (Ao) and caval flow (superior vena cava [SV...
La Constitución de 1991 determinó la obligación al Congreso República expedir un estatuto general contratación pública, razón por cual fue expedida Ley 80 1993, buscó otorgar mayor autonomía a las entidades estatales para contratar los bienes y servicios, mediante formulación principios generales, que evitaban regular el procedimiento contractual en detalle. Sin embargo, iniciando siglo XXI, va...
Small cell prostate carcinoma (SCPC) has a clinical course and prognosis that is markedly different from that of common adenocarcinoma of the prostate. The patient in this case presented with fever of unknown origin, dyspnea, and near spinal cord compression. He was subsequently found to have widely metastatic high-grade neuroendocrine carcinoma of prostatic origin. This case emphasizes that de...
Transition metal (TM) embedded two-dimensional phthalocyanine (Pc) sheets have been recently synthesized in experiments [M. Abel, S. Clair, O. Ourdjini, M. Mossoyan, and L. Porte, J. Am. Chem. Soc. 133, 1203 (2010)], where the transition metal ions are uniformly distributed in porous structures, providing the possibility of capturing gas molecules. Using first principles and grand canonical Mon...
A Modular Multistage Approach to Digital Fdm Demultiplexing for Mobile Scpc Satellite Communications
A hierarchical multistage method (HMM) for digital clemultiplexing of an FDM signal composed of L adjacent SCPC signals is described; L is (preferably) a power of two, here L=32. This I-IMM approach to FDM dernultiplexing applies bandpass sampling and is based on the processing of complexvalued signals by linear-phase FIR filters, where at any stage of processing the respective signals are alwa...
PURPOSE Clinical features characteristic of small-cell prostate carcinoma (SCPC), "anaplastic," often emerge during the progression of prostate cancer. We sought to determine the efficacy of platinum-based chemotherapy in patients meeting at least one of seven prospectively defined "anaplastic" clinical criteria, including exclusive visceral or predominantly lytic bone metastases, bulky tumor m...
Developing countries have experienced a dramatic increase in the number of clinical studies in the last decades. The aim of this study was to describe 1) the number of clinical trials submitted to the Brazilian Health Surveillance Agency (Agência Nacional de Vigilância Sanitária, Anvisa) from 2007 to 2012 and the number of human-subject research projects approved by research ethics committees (...
