[Demonstration of plasminogen activators in the saliva of a predatory insect of the family of Reduviidae (Heteroptera)].
The study of digestive and salivary proteases of Rhapactor biparticeps, has shown that the salivary glands of this insect are rich in proteolytic enzymes, however, the gut has none. TheExpand

[A new plasminogen activator isolated from the saliva of Rhapactor biparticeps (Heteroptera, Reduviidae): biological and physicochemical properties].
A new plasminogen activator has been isolated from the saliva of Rhapactor biparticeps. This product is 5% of salivary proteins and acts at an optimal pH of 7.8.P.D.F which results from its action onExpand

[Immunological similarities between two cerebral substances from Schistocerca gregaria and two neurohormones from Locusta migratoria].
Two neurohormones produced by two distinctive neurosecretory median cells (A1, B) of the protocerebum have been characterized in Locusta migratoria; on with a multiple functions one calledExpand

[Identification of plasminogen activators in the saliva of Rhapactor biparticeps (Reduviidae)].
Plasminogen activators are identified in the saliva of Rhapactor biparticeps using a particular technique which includes human fibrin in polyacrylamide gel. This technique is described and resultsExpand

[Demonstration of an enzyme inhibiting coagulation of blood ingested by the blood-sucking insect, Rhodnius prolixus (Heteroptera, Reduviidae)].
A new fibrinolytic enzyme, "the prolixase", was isolated and purified from the haemolymph of Rhodnius Prolixus. The mode of action of the enzyme was studied and compared to that of extracts fromExpand
Description of new fibrinolytic enzyme, isolated from the haemolymph of Rhodnius prolixus Stal (Heteroptera Reduviidae).
A new fibrinolytic enzyme, isolated from the haemolymph of Rhodnius prolixus Stal (Heteroptera, Reduviidae) has been discovered. This enzyme does not act by activating plasminogen to plasmin.Expand
[Prolixase, a fibrinolytic enzyme isolated from Rhodnius prolixus (Heteroptera, Reduviidae): antigenic properties].
Antigenic properties of prolixase are studied showing that this fibrinolytic enzyme, induces in the rabbit, the formation of precipitating but slightly, hemagglutinating homologous antibodies.
[Parasitic effect of Opius concolor (Spzl) (Hymenoptera, Braconidae) on an intermediate host Ceratitis capitata Wied (Diptera, Trypetidae)].
The parasitic incidence of Opius concolor (Hymenoptera, Braconidae) on a replacement host, Ceratitis capitata (Diptera, Trypetidae) was studied using polyacrylamide gel electrophoresis andExpand
[Characterization of vitellogenins and vitellines in Ceratatitis capitata (Diptera, Trypetidae): electrophoretic and immunoelectrophoretic study].
Electrophoretic study of haemolymphatic proteins in Ceratitis capitata has allowed to establish a proteic sexual dimorphism in this insect. This consists in a proteic fraction which is specific toExpand
[Salivary glands of Myzus persicae (Homoptera, Aphididae): structure and secretory rhythm].
The salivary glands of Myzus persicae (Homoptera, Aphididae): structure and secretory rythm. Studying the structure of the salivary glands of Myzus persicae, a particular mode of working of theseExpand
