Formaldehyde at low concentration induces protein tau into globular amyloid-like aggregates in vitro and in vivo. [PDF]

PLoS ONE, 2007
Recent studies have shown that neurodegeneration is closely related to misfolding and aggregation of neuronal tau. Our previous results show that neuronal tau aggregates in formaldehyde solution and that aggregated tau induces apoptosis of SH-SY5Y and ...

Reactivity of Larch and Valonia Tannins in Synthesis of Tannin-Formaldehyde Resins

BioResources, 2016
Tannin-formaldehyde resins (TFR) were prepared by copolycondensation of tannins (larch tannin or valonia tannin) and formaldehyde. The performances of TFR and the free formaldehyde residue in the system during the course of reaction were tested. Chemical
