Mechanisms of genotoxic effects of hormones [PDF]
, 2002 A concept that compounds commonly present in biological systems lack genotoxic and mutagenic activities is generally in use, hence a low number of endogenous substances have ever been tested to mutagenicity.

Chemo‐Enzymatic Route for Covalent Cellulose Fiber Dyeing
Chemistry – A European Journal, EarlyView.This work presents a proof of concept for a chemo‐enzymatic approach to the covalent dyeing of cotton fibers. Laccase/TEMPO oxidation introduces aldehyde groups, enabling subsequent reductive amination with amino dyes. Excellent color homogeneity and wash fastness were demonstrated using acid red 33, highlighting the robustness of the approach and its ...

Genes of the serotonergic and dopaminergic pathways and their interaction affect the expression of Behavioural and Psychological Symptoms in Dementia (BPSD). [PDF]
, 2009 Although there is evidence for the involvement of genes of serotonergic and dopaminergic systems in the manifestation of the Behavioural and Psychological Symptoms in Dementia (BPSD), genetic association studies are contradictory.

Biological functions controlled by manganese redox changes in mononuclear Mn-dependent enzymes [PDF]
, 2017 Remarkably few enzymes are known to employ a mononuclear manganese ion that undergoes changes in redox state during catalysis. Many questions remain to be answered about the role of substrate binding and/or protein environment in modulating the redox ...
