The present invention is in the field of antioxidants and relates to cosmetic or pharmaceutical, preferably dermatological, compositions or homecare product comprising or consisting of a synergistic combination of a specific antioxidant and an effective amount of 1,2-heptanediol and/or 2,3-heptanediol or of a specific alkanediol or a mixture of two or more different specific alkanediols and the use of said compositions as a cosmetic, for personal care, as a pharmaceutical or homecare product, in particular for scavenging reactive oxygen species (ROS), for inhibition matrix metalloproteinases expression and/or for inhibiting interleukin 8 (IL-8) secretion. Additionally, the present invention relates to the use of 1,2-heptanediol and/or 2,3-heptanediol or of a specific alkanediol or a mixture of two or more different specific alkanediols for enhancing the antioxidative effect of an antioxidant in a cosmetic or pharmaceutical, preferably dermatological, composition or homecare product, and/or for enhancing the antioxidative effect of a cosmetic or pharmaceutical, preferably dermatological, composition upon application.

The present invention relates to noninvasive microbiome analyses of Barrett's esophagus (BE) patients in which changes in the relative abundance of certain bacteria indicate a disease likelihood or pathogenic state. Additional aspects of the present invention relate to manipulating the microbiome to treat or prevent BE and related conditions. Embodiments also include monitoring for development of disease or monitoring treatment for prevention or elimination of disease states.
