Fungal pathologies caused by the genus Candida have increased in recent years due to involvement of immunosuppressed people and advance resistance mechanisms acquired these microorganisms. Liposomes are nanovesicles with lipid bilayers which they store compounds. ?-Bisabolol is a sesquiterpene proven biological activities, this work it was tested alone liposomes association Fluconazole vitro ev...

The paper presents a molecular modeling and docking studies on the interactions between natural αand β-cyclodextrin and the main biocompounds from Compositae family plants. Both vacuum and water periodic box conditions were used for the docking experiments. A comparative study on the formation and stability of complex obtained with non-oxidized/oxidized forms of biocompounds was performed. The ...

Copper is one of the heavy metal in plant that causes toxicity at high concentration via producing reactive oxygen species. Nitric oxide can protect cells from oxidative stress produce by reactive oxygen species. Effect of different concentrations of copper (1000, 1500 and 2000 μM) and interaction with nitric oxide (100 and 150 μM) were studied on growth parameters (shoot and root length) and s...

The aim of the present study was to isolate cyanobacteria from oil refinery waste water and detection of antagonistic activity of their extracts on four species of pathogenic bacteria. The cyanobacterium was isolated and purified on Blue green algae medium number 11 (BG-11) medium. Methanol and water extracts prepared from the cultured cyanobacterium after 45 days growth on BG-11 medium. The bi...

This work analyzed the chemical compositions and evaluated antioxidant cytotoxic activities of essential oils (EO) Eugenia patrisii (Epat), stipitata (Esti), Myrcia splendens (Mspl), sylvatica (Msyl), Psidium guajava (Pgua), guineense (Pgui-1 Pgui-2) from Brazilian Amazon. Sesquiterpenoids were found in high concentrations E. M. splendens, which rich E-caryophyllene (32.0% 45.8%); sylvatica, di...
