Federico II de Prusia : el rey flautista

En un momento histórico en el que las tendencias musicales en Europa estaban a medio camino entre el Barroco y el Clasicismo, confluyeron en la corte de Federico el Grande una serie de músicos que trabajaron para el rey prusiano y que compusieron una gran cantidad de música para flauta, instrumento que él tocaba. La actividad musical del Berlín de esos años se convirtió así en relevante para el mundo flautístico. Profundizaremos en este trabajo en la figura del monarca, en la relación de éste con sus músicos y en las características principales de la música de la segunda mitad del siglo XVIII.

Development of a Selective Peptide Macrocycle Inhibitor of Coagulation Factor XII toward the Generation of a Safe Antithrombotic Therapy.

Inhibition of coagulation factor XII (FXII) activity represents an attractive approach for the treatment and prevention of thrombotic diseases. The few existing FXII inhibitors suffer from low selectivity. Using phage display combined to rational design, we developed a potent inhibitor of FXII with more than 100-fold selectivity over related proteases. The highly selective peptide macrocycle is a promising candidate for the control of FXII activity in antithrombotic therapy and a valuable tool in hematology research.

Hypotensive effect of the active fragment derived from factor XII is mediated by an activation of the plasma kallikrein-kinin system.

Plasma protein fraction (PPF) contaminated by factor XII active fragment (XIIf) may cause hypotensive reactions when infused to patients. This study was planned to assess in conscious normotensive rats whether the blood pressure response to the factor XIIf is mediated by an activation of the plasma kallikrein-kinin system or by stimulation of prostaglandin synthesis. To test whether the factor XIIf-induced blood pressure fall is due partially to an enhanced generation of vasodilating prostaglandins, the blood pressure effect of XIIf (1 microgram i.v.) was investigated 15 min after treatment with indomethacin (5 mg i.v.), an inhibitor of cyclo-oxygenase. Factor XIIf reduced mean blood pressure similarly in indomethacin- and vehicle-treated rats (-23 +/- 4 mmHg, n = 5, and -23 +/- 5 mmHg, n = 4, respectively). Other rats received factor XIIf 15 min after depletion of circulating prekallikrein by the administration of dextran sulfate. Thirty minutes after a 0.25 mg i.v. dose of this agent, plasma prekallikrein activity averaged 0.12 +/- 0.015 mumol/min/ml (n = 6) as compared to 2.48 +/- 0.31 mumol/min/ml in control rats (n = 4, P less than .001). Factor XIIf decreased mean blood pressure by only 4 +/- 2 mm Hg in rats pretreated with dextran sulfate. Thus, it was possible to blunt the acute hypotensive effect of factor XIIf by depleting circulating prekallikrein, but not by inhibiting prostaglandin production. This strongly suggests that the blood pressure effects of factor XIIf is mediated by a stimulation of the plasma kallikrein-kinin system.

A comunicação política na web 2.0: estudo de caso sobre os perfis do Presidente de República Jorge Carlos Fonseca e do Primeiro Ministro José Maria Neves no Facebook

No presente trabalho procuramos entender mais sobre o conceito da Web 2.0, pois apesar de esta fazer parte do quotidiano da nossa sociedade, são poucos que conhecem a sua evolução. A Web 2.0 trata-se de um espaço em que a interactividade é uma das peças chave. Essa característica introduz desenvolvimentos em conceitos como cidadania e democracia e marca um virar de página na comunicação e no marketing político. Esta monografia procura ainda, através de um estudo de caso, perceber de que forma é que os progressos introduzidos pela Web 2.0 são sentidos na forma como se opera a comunicação política em Cabo Verde.
