Garlic (Allium sativum L.) has a long history of use as culinary seasoning and source health-promoting compounds. In particular organosulphur compounds derived from the action alliinase on alliin are interest for their antimicrobial action. Due to seasonal nature garlic harvest, long-term storage is required ensure year-round supply high-quality bulbs. However, quality known deteriorate through...

The virulence and resistance of pathogenic microorganisms are promoted by quorum-sensing (QS) mediated traits biofilms. development antimicrobial agents which can reduce the incidence microbial disrupting establishment biofilms QS, constitute a suitable strategy to emergence strains that resistant antibiotics. In this study, 3-(1,3-dithian-2-ylidene) pentane-2,4-dione ( 1 ) ethyl-2-cyano-2-(1,3...

PACs (polycylic aromatic compounds) are air pollutants formed in incomplete combustion, e.g., vehicle engines. Vegetation can potentially remove substantial amounts and act as bioindicators of these pollutants. Increased knowledge the pollutant removal efficiencies different tree species is essential for understanding potential benefits trees provide urban residents. We investigated leaf/needle...

Garlic organosulphur compounds have been successfully used as redox anti-proliferative agents. In this work, we dissect the effects of diallyl disulphide (DADS) focusing on the events upstream of cell cycle arrest and apoptosis induced in neuroblastoma SH-SY5Y cells. We demonstrate that DADS is able to cause early morphological changes, cytoskeleton oxidation, microfilaments reduction and depol...
