Structural insight on organosilica electrodes for waste-free alcohol oxidations
2007
Organic modification of sol-gel catalytic glassy electrodes made of a thin layer of organosilica doped with nitroxyl radical TEMPO (2,2,6,6-tetramethyl-1-piperidinyloxy) crucially enhances stability in the waste-free oxidation of alcohols to carbonyls in water. Structural comparison between analogous films made of organosilica and unmodified SiO2 shows that the origin of the pronounced stable activity of the ORMOSIL film lies in high hydrophobic and also in the pronounced low degree of hydrophilicity.
In vitro synthesis of factor B of the alternative pathway of complement activation by mouse peritoneal macrophages
1976
Factor B of the alternative pathway of complement activation was shown to be synthesized and secreted by unstimulated mouse peritoneal macrophages. The activity of B in the culture supernatants from macrophage monolayers was detected by consumption of C3 in reaction mixtures containing supernatant and guinea pig factors C3, D and insoluble C3b. Using a monospecific antiserum, factor B in concentrated culture supernatants was shown by immunodiffusion and immunoelectrophoresis to be identical to factor B in mouse plasma and to form a characteristic complex with cobra venom factor in the presence of D. A steady rate of factor B secretion was observed for 4 days providing the medium was changed…

Calidad de la atención al paciente oncológico: Tiempos asistenciales recomendables entre sospecha clínica y definición del plan terapéutico en cáncer…
2012
Fundamento. Determinar tiempos recomendables para el tratamiento desde la sospecha clínica fundada en los procesos asistenciales de cáncer de mama y colorrectal considerando factibilidad y situación personal del paciente. Método. Estudio cualitativo de búsqueda de consenso entre profesionales. Primero, se revisaron mediante 4 sesiones grupales (N=19), los procesos asistenciales de cáncer de mama y cáncer colorrectal y se fijaron los tiempos deseables de ambos procesos. Segundo, mediante una modificación de la técnica Delphi (N=49), se validó la propuesta de tiempos de atención recomendables para cada proceso asistencial. Resultados. La tasa de respuesta en el estudio Delphi fue del 69% en e…
HIV und Schwangerschaft: Risiken der Übertragung und therapeutische Möglichkeiten
1996
Die Rate der vertikalen Ubertragung von HIV im Rahmen einer Schwangerschaft liegt in Europa bei etwa 14% aller HIV-infizierten Schwangeren. Risikofaktoren sind: 1. Virusmenge gemessen an p-24-Antigenamie und Hohe der HIV-RNA-Serumkonzentrationen, 2. Abfall der CD4-Lymphozyten unter 600/µl, 3. Chorioamnionitis und 4. Zeitintervall zwischen Blasensprung und Entbindung. Stillen und vaginale Entbindung erhohen die HIV-Infektionsrate des Kindes. Durch antiretrovirale Therapie mit Azidothymidin (Retrovir®) in einer Dosis von 500 mg/Tag wird die vertikale Ubertragung um 67% reduziert. Teratogene oder mutagene Nebenwirkungen sind bisher nicht nachgewiesen worden. Die Progression der HlV-Infektion d…

Lymphoid lesions of salivary glands : malignant and Benign
2007
Lesions of salivary glands with a prominent lymphoid component are a heterogeneous group of diseases that include benign reactive lesions and malignant neoplasms. Occasionally, these pathologic entities present difficulties in the clinical and pathological diagnosis and prognosis. Lymphoepithelial sialadenitis, HIV-associated salivary gland disease, chronic sclerosing sialadenitis, Warthin tumor, and extranodal marginal zone B-cell lymphoma are examples of this pathology that are sometimes problematic to differentiate from one another. In this paper the author reviewed the main clinical, pathological and prognostic features of these lesions.
