The idiopathic myocardiopathy of the peripartum (IMPP) is a frequent disease in the Soudano-Sahelian zone of Africa whose evolution is loaded with many complications hemodynamic, thrombo-embolic and rhythmic. The prevalence and the meaning of the rhythm disorders are unknown. The aims of this prospective study are to measure and to describe the prevalence(More)
We have used the impedance aggregometer to study the "ex vivo" effect of acetylsalicylic acid (ASA) in whole blood (WB) versus platelet-rich plasma (PRP) in 35 male healthy volunteers after 10 days of treatment with 25, 50, 125, 250, and 500 mg/day of ASA. Percent of inhibition of platelet aggregation was determinated at the end of treatment. A greater(More)
We have used the impedance aggregometer to study the in vitro effect of acetylsalicylic acid (ASA) in whole blood (WB) versus platelet-rich plasma (PRP) using blood samples from 24 male and 24 female healthy volunteers. IC50 was calculated from dose-response curves of ADP-, adrenaline-, collagen- and arachidonic acid-induced aggregation. ASA inhibited(More)
This paper presents an oscillator design technique for low-power applications. The circuit is based on the common-gate Colpitts oscillator with additional positive feedback provided by an inductive gate degeneration. This technique decreases the required transconductance to start-up oscillations, which makes possible to reduce the power consumption. Two(More)
The antiproteinuric effect of the antiplatelet agent dipyridamole has been assessed after inhibiton of thromboxane B2 (TxB2) synthesis in 8 patients with confirmed membranous glomerulonephritis. There were three study periods, each of 30 days, and 45 days apart, namely a washout period, treatment with dipyridamole 300 mg/d, and dipyridamole 225 mg/d plus(More)
An oscillator design technique for low-power and low-voltage applications is presented. The circuit is based on the classical common-gate Colpitts oscillator with additional positive feedback provided by an inductive gate degeneration. This technique decreases the required transconductance to startup oscillations, which makes possible to reduce the minimum(More)
The aim of the present study is to evaluate the effect of dipyridamole (300 mg/day) versus placebo in a double-blind randomized trial on membranous glomerulonephritis (M-GMN), mesangial IgA glomerulonephritis (IgA-GMN), and segmentary and focal hyalinosis glomerulonephritis (SFH-GMN) during the first 3 months of treatment. In the case of M-GMN, proteinuria(More)
