A critical and annotated catalogue of 52 types of Chrysididae belonging to 32 species deposited in the Zoological Museum of Moscow Lomonosov State University is given. The lectotypes of Chrysis sabulosa Radoszkowski, 1877 and Ellampus (Philoctetes) fedtschenkoi Semenov, 1932 are designated. New synonyms are proposed for (valid name first): Omalus imbecillus (Mocsáry, 1889) = Ellampus kozhevniko...

This work was carried out on Allium roseum L., a North African endemic species, growing in the South-East of Tunisia and used as a vegetable, spice or herbal remedy in traditional medicine. Three protocols of extraction (Tris HCl buffer, phosphate buffer and sulphuric acid) were used in order to extract proteins from four different organs of this species (flowers, bulbs, leaves and seeds). Tris...

Biotransformation of ent-3beta,12alpha-dihydroxy-13-epi-manoyl oxide with Fusarium moniliforme gave the regioselective oxidation of the hydroxyl group at C-3 and the ent-7beta-hydroxylation. The action of Gliocladium roseum in the 3,12-diketoderivative originated monohydroxylations at C-1 and C-7, both by the ent-beta face, while Rhizopus nigricans produced hydroxylation at C-7 or C-18, epoxida...

In this work we highlight a possible synergistic anti-Candida effect between Melaleuca alternifolia, Origanum vulgare and Pelargonium graveolens essential oils and the antifungal compound Amphotericin B. The antifungal activity was assessed using the agar dilution method in eleven Candida strains. The results obtained indicate the occurrence of a synergistic interaction between the essential oi...

Several diseases of geraniums (Pelargonium species) are caused by viruses. The economic losses caused by these diseases are difficult to assess since infected plants are often symptomless and because both the cultivar and the environment in which the plants are growing can greatly influence the severity of the symptoms. The problem is compounded by the diverse sources of stock plants and the fa...
