Regioselective aromatic hydroxylation is desirable for the production of valuable compounds. External flavin-containing monooxygenases activate and selectively incorporate an oxygen atom in phenolic compounds through flavin reduction by the nicotinamide adenine dinucleotide coenzyme, and subsequent reaction with molecular oxygen. This study provides the proof of principle of flavoenzyme-catalyzed selective aromatic hydroxylation with coenzyme biomimetics. The carbamoylmethyl-substituted

... ic in particular affords full conversion in less than two hours for the selective hydroxylation of 5 mM 3and 4-hydroxybenzoates, displaying similar rates as with NADH, achieving a 10 mM/h enzymatic conversion of the medicinal product gentisate. This biomimetic appears to generate less uncoupling of hydroxylation that typically leads to undesired hydrogen peroxide. Therefore, we show these flavoenzymes have the potential to be applied in combination with biomimetics.

Negotiation and trade typically require a mutual interaction while simultaneously resting in uncertainty which decision the partner ultimately will make at the end of the process. Assessing already during the negotiation in which direction one's counterpart tends would provide a tremendous advantage. Recently, neuroimaging techniques combined with multivariate pattern classification of the acquired data have made it possible to discriminate subjective states of mind on the basis of their

... l activation signature. However, to enable an online-assessment of the participant's mind state both approaches need to be extended to a real-time technique. By combining real-time functional magnetic resonance imaging (fMRI) and online pattern classification techniques, we show that it is possible to predict human behavior during social interaction before the interacting partner communicates a specific decision. Average accuracy reached approximately 70% when we predicted online the decisions of volunteers playing the ultimatum game, a well-known paradigm in economic game theory. Our results demonstrate the successful online analysis of complex emotional and cognitive states using realtime fMRI, which will enable a major breakthrough for social fMRI by providing information about mental states of partners already during the mutual interaction. Interestingly, an additional whole brain classification across subjects confirmed the online results: anterior insula, ventral striatum, and lateral orbitofrontal cortex, known to act in emotional self-regulation and reward processing for adjustment of behavior, appeared to be strong determinants of later overt behavior in the ultimatum game. Using whole brain classification we were also able to discriminate between brain processes related to subjective emotional and motivational states and brain processes related to the evaluation of objective financial incentives.

Real-time functional MRI (rfMRI) offers new experimental paradigms, such as biofeedback and interactive experiments. Usually, several separated software systems are used to control the MRI measuring sequence, the stimulus presentation, and the statistical analysis, which leads to problems concerning the user communication and synchronisation and interaction of the different software systems. Here, an approach is developed which helps to overcome those difficulties by utilising a uniform

... r management using a flexible parameter description that can be used simultaneously by different separated software systems. This approach is used to control two modules: a realtime fMRI application which extracts the current activation, and an analysis-system which evaluates the current brain activation to influence the stimulus presentation and provide feedback to the volunteer.
