Abstract Increasing biological activity and phytochemical investigations on Eryngium species showed its potential as pharmaceutical approach. Eryngium kotschyi Boiss. is one of the species of Eryngium genus and is endemic to Turkey. It is known that this plant is traditionally used in the South-western ...

In vitro evaluation of the cytotoxicity and eye irritation potential of preservatives widely used in cosmetics

Abstract The consumption of cosmetics has been increasing every year and is expected to reach $675 billion by 2020 at an estimated growth rate of 6.4% per year. Exposure to skin irritants is the major cause of non-immunological inflammation of the skin. Therefore, the safety evaluation of cosmetic preser...

Selective Cytotoxic effect of Probiotic, Paraprobiotic and Postbiotics of L. casei strains against Colorectal Cancer Cells: Invitro studies

Abstract This study highlights the cytotoxic effect of three L. casei strains on colorectal cell lines in invitro conditions. Different concentrations of live, heat killed (HK) and cell free supernatant (CFS) of three L.casei strains were subjected to CaCo2 and MRC5 cell lines. The viability of the treat...
