We used fuorescent microsphere particles to simulate cell retention and biodistribution after cardiac regenerative therapy. Fibrinogen was evaluated to augment particle retention.

A basket of currencies is constructed using objective probabilities (propensities) and an artificial intelligence optimization technique that allows for implicit learning of correlations dynamics. Statistical tests of the diversification benefit are presented.

Our results show that these proteins indeed interact and that the interaction is not affected by MAP1B phosphorylation. Additionally, neurons lacking MAP1B, when exposed to drugs that reversibly depolymerize microtubules, do not fully recover tyrosinated microtubules upon drug removal. These results suggest that MAP1B regulates tyrosination of ␣ -tubulin in neuronal microtubules. This regulation may be important for general processes involved in nervous system development such as axonal guidance and neuronal migration.
