conclusions the results of the present study show a favorable inhibitory effect of artemisias spicigera essential oil on fungal growth, especially aspergillus species. according to the results, antifungal components of artemisias spicigera in different forms are used to prevent fungal pollution. materials and methods two types of media dichloran 18% glycerol (dg18) agar and dichloran rosebengal...

We show that a twistor space of a self-dual metric on 4CP with U(1)-isometry is not Moishezon iff there is a C∗-orbit biholomorphic to a smooth elliptic curve, where the C∗-action is the complexification of the U(1)action on the twistor space. It follows that the U(1)-isometry has a two-sphere whose isotropy group is Z2. We also prove the existence of such twistor spaces in a strong form to sho...

Epidermodysplasia verruciformis is an inherited disorder, characterized by multiple plane warts, pityriasis versicolor-like lesions, defects of cell-mediated immunity, and tendency to develop skin malignancies, primarily on sun-exposed areas. In this article, we present a case of epidermodysplasia verruciformis with multiple plane warts, pityriasis versicolor-like lesions, and squamous cell car...

Isometric twitch and tetanus parameters, force-velocity curves, maximum shortening velocity (Vmax) and percentage relaxation between stimuli (%R) across a range of stimulus frequencies were determined for a muscle used during call production (the tensor chordarum) and a locomotor muscle (the sartorius) for three species of hylid frogs, Hyla chrysoscelis, H. versicolor and H. cinerea. The call o...

Polychlorinated biphenyls (PCBs) are widespread persistent pollutants deleterious for environment and very dangerous human kind. As the bioremediation of PCB polluted sites by model white-rot fungi is still unsatisfactory, use efficient native strains which have natural capacity to develop on may constitute a relevant alternative strategy. In this study, we isolated 12 fungal from contaminated ...

The mushroom Flammulina velutipes and the white-rot fungus Trametes versicolor were cultivated separately on sugarcane bagasse for 40 days. Trametes versicolor produced laccase and manganese-peroxidase activities, showing a simultaneous degradation of lignin and holocellulose. However, only phenoloxidase activity was found with Flammulina velutipes. A preferential degradation of lignin was dete...
