Defining and Measuring Developmental Regression During Childhood: A Scoping Review

Autism Research, EarlyView.
ABSTRACT Developmental regression during childhood is inconsistently defined and measured, resulting in delayed diagnostic discovery and intervention. This study aimed to examine published definitions and measures for developmental regression. A comprehensive search strategy was applied to Medline, Embase, Cochrane, and PsycINFO databases.

Modular One‐Pot Access to π‐Expanded Tetrakis(Phenothiazinyl)‐Silanes With Broadly Tunable Redox and Emission Properties

Chemistry – A European Journal, EarlyView.
A library of 21 tetrakis(phenothiazinyl)‐substituted silanes with broadly variable substituent decoration, which are fully reversible multistage redox systems with intense tunable emission from deep blue to yellow–green (441–533 nm), was rapidly synthesized by bromine–lithium exchange/borylation–Suzuki coupling of tetrakis(4‐bromophenyl)silane or by ...
