The transmission pathways of Helicobacter pylori in humans have not been fully elucidated. Research in the last decade has proposed that foodborne transmission, among others, may be a plausible route of human infection. Owing to the organism's fastidious growth characteristics and its ability to convert to viable, yet unculturable states ...

Environmental factors including stressors, health status and social context significantly affect carotenoid-based coloration. For instance, stressors may induce the diversion of carotenoids from pigmentation pathways, potentially explaining why stressed animals often exhibit reduced coloration. However, we recently showed that high blood corticosterone concentrations, which are part of the physiological stress ...
