Syntheses, transformations and applications of aminonaphthol derivatives prepared via modified Mannich reactions [PDF]
A special alteration is the three-component modi fi ed Mannich reaction (mMR), in which formaldehyde is replaced by an aromatic aldehyde, the secondary amine by ammonia, and the C e H acid by an electron-rich aromatic compound such as 1- or 2 ...

Lineage labeling with zebrafish hand2 Cre and CreERT2 recombinase CRISPR knock‐ins
Abstract Background The ability to generate endogenous Cre recombinase drivers using CRISPR‐Cas9 knock‐in technology allows lineage tracing, cell type‐specific gene studies, and in vivo validation of inferred developmental trajectories from phenotypic and gene expression analyses. This report describes endogenous zebrafish hand2 Cre and CreERT2 drivers
