In the presence of endodontic gutta-percha cones, several species of bacteria were killed in vitro. Silver points, when compared with gutta-percha cones, were not or were considerably less effective against the target organism. Staphylococcus aureus, in our assay system. Growth of bacteria in serum could be abolished by the mere presence of gutta-percha,(More)
Growth of several species of bacteria was inhibited by the presence of endodontic gutta-percha cones. Microbiologic analysis, measurement of osmolarity, microscopy, x-ray diffraction analysis, and scanning electron micrography were used to identify the biologically active component that slowly leaches from gutta-percha cones. This component is zinc oxide in(More)
BACKGROUND Proquinazid is a new quinazolinone fungicide from DuPont registered in most European countries for powdery mildew control in cereals and vines. The aim of this paper is to present baseline sensitivity data in populations of Blumeria graminis f. sp. tritici EM Marchal and Erysiphe necator (Schw) Burr as well as results from cross-resistance(More)
Resistance to QoI fungicides (strobilurins, famoxadone and fenamidone) in populations of Plasmopara viticola (Berk & Curt) Berlese & de Toni developed soon after their introduction in France and Italy. Current resistance management strategies include limitation of the number of applications, use of mixtures and alternation of fungicides with different modes(More)
Cymoxanil has been used for over 30 years to control grape downy mildew (Plasmopara viticola) in European vineyards, prevalently in mixture with other fungicides active on this disease. In the 1990’s cases of P. viticola resistant to cymoxanil were detected using a leaf disc assay. In this study, we establish that the presence of only 1 % of resistant(More)
The contribution of atrial natriuretic factor to the development of spontaneous arterial hypertension was investigated in rats (the SHR line). Prehypertensive atrial and plasma levels of a natriuretic factor were similar in SHR to those of the control WKY rats. In fully-developed hypertension, the factor content decreases in left-atrial wall and increases(More)
