A Multiscale Mechanistic Framework for Polydopamine Dyeing in Ultrablack Wool Textiles

Advanced Science, EarlyView.
Ultrablack photonic textiles are enabled through polydopamine (PDA) dyeing, which is governed by the interplay of PDA chemistry, wool surface topology and chemistry, and hierarchical fiber–yarn–fabric architecture. Fabric architecture emerges as a primary and previously underappreciated design lever for wide‐angle optical performance.

Mussel-inspired adhesive protein-based electrospun nanofibers reinforced by Fe(iii)-DOPA complexation.

Journal of materials chemistry. B, 2015
Marine mussels utilize multiple bidentate complexes formed by Fe(iii) and DOPA in a mussel adhesive protein (fp-1) to reinforce tough and elastic byssal fibers as a specialized underwater adhesive aid.

A systematic review on drugs absorption modifications after eradication in Helicobacter pylori positive patients undergoing replacement therapy [PDF]

, 2015
Background & Aims: Helicobacter pylori (H. pylori) infection has been suggested as a cause of impaired drug absorption. This infection leads to alteration of the gastric acid secretion that may change the conformational characteristics of drugs and their

The Role of Glutamatergic and Dopaminergic Genes in Resistant Schizophrenia: A Systematic Review

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Psychosis is a heterogeneous disorder, with approximately one‐third of patients experiencing treatment resistance, predominantly among individuals diagnosed with Schizophrenia. Treatment‐resistant schizophrenia (TRS) may stem from a distinct biological signature, involving abnormalities in the dopaminergic and glutamatergic systems.

Enhancement of L-Dopa Incorporation into Melanoma by Dopa Decarboxylase Inhibition

Journal of Investigative Dermatology, 1978
Melanoma cells possess a special biochemical pathway for the conversion of L-dopa to melanin. Selective incorparation of exogenous L-dopa into melanoma cells in vivo has been limited by extensive decarboxylation to dopamine. Pretreatment of animals bearing the S-91 Cloudman or ACI melanomas with Ro4-4602, a potent dopa decarboxylase inhibitor limited ...

Changes in extracellular and intracellular L-DOPA concentration in methyl-L-DOPA-pretreated primary cultured striatal astrocytes after withdrawal of L-DOPA.

, 2014
Striatal astrocytes were treated with methyl-L-DOPA (200 µM) for 4 h or 8 h (filled bar). Furthermore, astrocytes pre-treated with methyl-L-DOPA for 8 h were incubated in fresh medium for 1 h or 4 h (gray bar).

Transformative Chemie maskierter Ortho‐Chinone: Über die direkte Aktivierung von Guajacol zu Lignin‐basierten Klebstoffen

Angewandte Chemie, EarlyView.
Erneuerbare Guajacole werden durch Phenyliodid(III)diacetat rasch zu maskierten ortho‐Chinonen oxidiert und bilden eine neue Monomerklasse, die mit Multithiolen selektive Michael‐Typ‐Polyadditionen zu Polymeren mit Thiol‐Guajacol‐Verknüpfungen eingeht.

Nitric oxide synthase inhibition decreases l-DOPA-induced dyskinesia and the expression of striatal molecular markers in Pitx3(-/-) aphakia mice.

Neurobiology of Disease, 2015
Nitric oxide (NO), a gaseous messenger molecule synthesized by nitric oxide synthase (NOS), plays a pivotal role in integrating dopamine transmission in the basal ganglia and has been implicated in the pathogenesis of Parkinson disease (PD). To study the
