Journal ArticleDOI
Are naringenin and quercetin useful chemicals in pest-management strategies?
TL;DR: In this paper, the effects of two polyphenolic flavonoids (flavanone naringenin and flavonol quercetin) on development, fecundity, and mortality of Acyrthosiphon pisum Harris (Hemiptera: Aphididae) were determined in vitro, on an artificial diets.
Journal ArticleDOI
Expression of the Biofilm-Associated Genes in Methicillin-Resistant Staphylococcus aureus in Biofilm and Planktonic Conditions.
TL;DR: The role of genes that are essential for development of Staphylococcus aureus biofilm during infection is not fully known as discussed by the authors, but the expression levels of investigated genes under biofilm conditions were significantly higher than under planktonic conditions.
Journal ArticleDOI
Aphicidal activity of selected Asteraceae essential oils and their effect on enzyme activities of the green peach aphid, Myzus persicae (Sulzer).
TL;DR: The obtained results suggest that essential oils from the studied Asteraceae plants can affect important biochemical processes within aphid tissues and may be considered as potent biopesticides in green peach aphid control.
Journal ArticleDOI
Antifungal activity of Juglans regia (L.) leaf extracts against Candida albicans isolates
Hubert Sytykiewicz,Grzegorz Chrzanowski,Paweł Czerniewicz,Bogumił Leszczyński,Iwona Sprawka,Robert Krzyżanowski,Henryk Matok +6 more
TL;DR: It has been elucidated that all tested strains were susceptible for nystatin and amphotericin B, and only one yeast strain was resistant to flucytosine, and the group of azole antimycotics were characterized by reduced effectiveness against the candidal isolates.
Journal ArticleDOI
Expression Profiling of Selected Glutathione Transferase Genes in Zea mays (L.) Seedlings Infested with Cereal Aphids
Hubert Sytykiewicz,Grzegorz Chrzanowski,Paweł Czerniewicz,Iwona Sprawka,Iwona Łukasik,Sylwia Goławska,Cezary Sempruch +6 more
TL;DR: The Ambrozja variety could be characterized as having more profound increments in the levels of gst transcript abundance and O2 •− generation in comparison with the Tasty Sweet genotype.
