objectives: the purpose of this study was to assay the antifungal activity of selected essential oils obtained from plants against both fluconazole (flu)-resistant and flu-susceptible c. albicans strains isolated from hiv positive patients with oropharyngeal candidiasis (opc). materials and methods: the essential oils were obtained by hydrodistillation method from myrtus communis (my. communis)...

during the last two decades, various medicinal plants have been studied for their possible antimicrobial activity to discover new antimicrobial agents capable of resolving problems such as the development of drug resistance in pathogenic microorganisms as well as the side effects of some present antibiotics. in this study, the antibacterial activity of methanolic extract of t. pubescens (rich i...

results the isolates were completely resistant to the tested antibiotics, with minimum inhibitory concentration (mic) values for ceftazidime, imipenem, and gentamicin between 256 to > 256 μg/ml, 8 to > 256 μg/ml, and 64 to > 256 μg/ml, respectively. the r. dentatus extract had a broad spectrum activity against all tested isolates and maximum growth inhibition against isolates from burn wound an...

Although most investigators agree that the action of phenol is due to some general chemical or physico-chemical mechanism (in recent publications, e.g., lysis of cell walls in gram positive forms, Gale and Taylor, 1947; denaturation of enzyme proteins, Fogg and Lodge, 1945) rather than to a particular metabolic interference by the compound, the eistence of naturally resistant strains (Harde and...

The occurrence of vancomycin-resistant Staphylococcus aureus (VRSA) and multidrug-resistant (MDR) strains of this organism necessitate the discovery of new classes of anti-staphylococcal drug leads. At present there are no single chemical entity plant derived antibacterials used clinically, and this biologically diverse group deserves consideration as a source of chemical diversity for two impo...

Elimination of cisplatin-resistant lung cancer cells remains a major obstacle. We have shown that cisplatinresistant tumorshavehigher reactiveoxygen species (ROS) levels and canbe exploited for targeted therapy.Here, we show that increased secretion of the antioxidant thioredoxin-1 (TRX1) resulted in lowered intracellular TRX1 and contributed to higher ROS in cisplatin-resistant tumors in vivo ...

Giant ragweed (Ambrosia trifida L.) and waterhemp (Amaranthus tuberculatus [Moq.] J.D.Sauer) are highly competitive the most troublesome weeds in corn (Zea mays soybean (Glycine max Merr.) cropping systems Wisconsin. Field experiments were conducted to evaluate efficacy of multiple foliar-applied POST-emergence herbicides on giant at Janesville, WI (2020 2021), groups 2- 9-resistant Brooklyn, (...
