A new model for simultaneous dimensionality reduction and time-varying functional connectivity estimation.

Authors:
Diego Vidaurre

PLoS Comput Biol 2021 Apr 16;17(4):e1008580. Epub 2021 Apr 16.

Center for Functionally Integrative Neuroscience, Department of Clinical Medicine, Aarhus University, Aarhus, Denmark.

An important question in neuroscience is whether or not we can interpret spontaneous variations in the pattern of correlation between brain areas, which we refer to as functional connectivity or FC, as an index of dynamic neuronal communication in fMRI. That is, can we measure time-varying FC reliably? And, if so, can FC reflect information transfer between brain regions at relatively fast-time scales? Answering these questions in practice requires dealing with the statistical challenge of having high-dimensional data and a comparatively lower number of time points or volumes. A common strategy is to use PCA to reduce the dimensionality of the data, and then apply some model, such as the hidden Markov model (HMM) or a mixture model of Gaussian distributions, to find a set of distinct FC patterns or states.

Interactive Regulation between Aliphatic Hydroxylation and Aromatic Hydroxylation of Thaxtomin D in TxtC: A Theoretical Investigation.

Inorg Chem 2021 Apr 16. Epub 2021 Apr 16.

Key Laboratory of Theoretical and Computational Photochemistry, Ministry of Education, Beijing Normal University, Beijing 100875, China.

TxtC is an unusual bifunctional cytochrome P450 that is able to perform sequential aliphatic and aromatic hydroxylation of the diketopiperazine substrate thaxtomin D in two distinct sites to produce thaxtomin A. Though the X-ray structure of TxtC complexed with thaxtomin D revealed a binding mode for its aromatic hydroxylation, the preferential hydroxylation site is aliphatic C. It is thus intriguing to unravel how TxtC accomplishes such two-step catalytic hydroxylation on distinct aliphatic and aromatic carbons and why the aliphatic site is preferred in the hydroxylation step.
