The Biarylitides: Understanding the Structure and Biosynthesis of a Fascinating Class of Cytochrome P450 Modified RiPP Natural Products

ChemBioChem, EarlyView.
The biarylitides are fascinating RiPP natural products with small core peptides and diverse peptide crosslinks performed by cytochrome P450 enzymes. Here, we address the discovery and diversity of the biarylitides, methods to analyse these constrained cyclic peptides, the structures of the biarylitide P450 enzymes and address alternate catalytic ...

Neuropsychiatric symptoms associated multimodal brain networks in Alzheimer's disease

Human Brain Mapping, Volume 44, Issue 1, Page 119-130, January 2023., 2023
Neuropsychiatric symptoms (NPS)‐associated multimodal pattern spatially involves frontal‐subcortical limbic circuits, which significantly associated with cognitive performance and progression. Different frontal‐subcortical limbic circuit regions suffer different pathogenic mechanisms in Alzheimer's disease subjects concomitant with NPS.

Artificial Intelligence‐Assisted Experimental Optimization of Water Oxidation Catalysts

Chemie Ingenieur Technik, EarlyView.
The use of active learning techniques is explored to optimize the startup phase of bulk nickel electrodes in the oxygen evolution reaction. The created dataset is utilized, dimension reduction is applied, and the information learned through an artificial neural network is extracted with an optimization routine.

Mapping Interictal activity in epilepsy using a hidden Markov model: A magnetoencephalography study

Human Brain Mapping, Volume 44, Issue 1, Page 66-81, January 2023., 2023
In this study, we use hidden Markov modeling (HMM) to create a unique statistical model of interictal brain activity for 10 pediatric epilepsy patients. This data‐driven model produces an output unique to each patient, and is used to localize the epileptogenic area(s).
