Phytoene and Phytoene-Rich Microalgae Extracts Extend Lifespan in and Protect against Amyloid-β Toxicity in an Alzheimer's Disease Model.

Phytoene is a colourless carotenoid widely available from dietary sources and a precursor for the synthesis of other carotenoids. Although present at high concentrations across different tissues, phytoene is largely viewed as not having physiological activity. Here, we utilize the model organism to show that phytoene is bioactive and has anti-ageing properties.

Controlling the structure of supramolecular fibre formation for benzothiazole based hydrogels with antimicrobial activity against methicillin resistant .

Antimicrobial resistance is one of the greatest threats to human health. Gram-positive methicillin resistant (MRSA), in both its planktonic and biofilm form, is of particular concern. Herein we identify the hydrogelation properties for a series of intrinsically fluorescent, structurally related supramolecular self-associating amphiphiles and determine their efficacy against both planktonic and biofilm forms of MRSA.
