Many unicellular flagellates are mixotrophic and access resources through both photosynthesis and prey capture. Their fitness depends on those processes as well as on swimming and predator avoidance. How does the flagellar arrangement and beat pattern of the flagellate affect swimming speed, predation risk due to flow-sensing predators, and prey capture? Here, we describe measured flows around ...

A critical step in the synthesis of the rare sugars, L-lyxose and L-ribose, from the corresponding D-sugars is the oxidation to the lactone. Instead of conventional oxidizing agents like bromine or pyridinium dichromate, it was found that a heterogeneous catalyst, Pd-Bi/C, could be used for the direct oxidation with molecular oxygen. The composition of the catalyst was optimized and the best re...

Previous in vivo studies indicate that locally injected redox-modulating agents can sensitize polymodal peripheral skin nociceptors resulting in acute changes in pain perception. Since endogenous thiol-modifying redox agents are normally present in the interstitial tissue, and could be found in higher concentration in certain conditions (e.g., tissue injury, inflammation, and ischemia), we desi...
