Whole tissue imaging of cellular boundaries at sub‐micron resolutions for deep learning cell segmentation: Applications in the analysis of epithelial bending of ectoderm

Developmental Dynamics, EarlyView.
Abstract Background To understand cellular morphology, biologists have relied on traditional optical microscopy of tissues combined with tissue clearing protocols to image structures deep within tissues. Unfortunately, these protocols often struggle to retain cell boundary markers, especially at high enough resolutions necessary for precise cell ...

Directed Hole Localization Stabilizing Interfacial Sulfur Species to Boost α‐C–H Activation for Selective Biomass Photo‐oxidation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Efficient α‐C–H bond activation and directional conversion for selective biomass photo‐oxidation are achieved by integrating polarization and interface engineering strategies in P‐doped ZnIn2S4 polar photocatalysts, which leverage hole localization and stable interfacial sulfur species, endowing bio‐based HMF at 94.4% conversion with 94.5% selectivity ...

The In Vitro Transgenic Rodent Assay in Primary MutaMouse Hepatocytes Compared to the Mammalian Cell Gene Mutation Assay Using the HPRT Gene

Environmental and Molecular Mutagenesis, EarlyView.
ABSTRACT Gene mutations can be detected in mammalian cells in vitro using indicator genes such as the hypoxanthine‐guanine‐phosphoribosyltransferase (HPRT) gene. These assays have been adopted as OECD test guidelines (TG, e.g., OECD TG no. 476) and are used for regulatory purposes.

Electrophotocatalytic Hydroxymethylation of Azaarenes with Methanol

Organic Letters
The merge of electrochemistry and photocatalysis allowed the required selectivity for the hydroxymethylation of functionalized azaarenes with methanol, including bioactive substrates. The two electrophotocatalytic protocols developed in this work address this transformation, using non-toxic and readily available reagents under mild reaction conditions ...

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

Environmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...
