L-3,4-dihydroxyphenylalanine Accumulation in Faba Bean (Vicia faba L.) Tissues during Different Growth Stages

Agronomy, 2021
L-3,4-dihydroxyphenylalanine (L-dopa)-rich faba (Vicia faba L.) tissues are a potentially useful source for its pharmaceutical purpose, although the species contains health curious vicine and convicine in the seeds.

A Dual‐Bioresponsive and Programmable Microneedle Matrix as a Bioinspired Coupler for Orchestrating Diabetic Bone Regeneration

Advanced Materials, EarlyView.
This project developed a smart bandage‐like patch (a microneedle array) for repairing diabetic bone damage. It intelligently senses signals from infection and inflammation, then releases its medicines in a specific, timed sequence: first an antibacterial agent, then an anti‐inflammatory agent, and finally growth factors.

Ferreascidin: A highly aromatic protein containing 3,4-dihydroxyphenylalanine from the blood cells of a stolidobranch ascidian

, 1987
A method of isolation and purification was developed for the major protein from the blood cells of the stolidobranch ascidian Pyura stolonifera. The protein, called ferreascidin because of its strong iron binding capacity (two Fe3+ per molecule), is the ...

Ambient Light‐Activatable Luminescent Particle‐Embedded Conformal Patch for Photochemical Tissue Bonding and Photobiomodulated Healing

Advanced Materials, EarlyView.
We report a wearable photonic patch integrating room light‐ and sunlight‐activatable luminescent particles (RSLPs) for both photochemical tissue bonding and photobiomodulation. RSLPs harvest ambient light and emit red luminescence to drive chlorin e6–mediated collagen crosslinking.

Effects of Quercetin on Mushroom Tyrosinase and B16-F10 Melanoma Cells

Molecules, 2007
In searching for tyrosinase inhibitors from plants using L-3,4-dihydroxyphenylalanine (L-DOPA) as a substrate, quercetin was found to be partially oxidized to the corresponding o-quinone under catalysis by mushroom tyrosinase (EC 1.14.18.1 ...

Chronic continuous and intermittent l-3,4-dihydroxyphenylalanine treatments differentially affect basal ganglia function in 6-hydroxydopamine lesioned rats-an autoradiographic study using [3H]flunitrazepam

, 1993
The effects of chronic 'continuous' and 'intermittent' l-3,4-dihydroxyphenylalanine treatments on GABA receptor function in the basal ganglia of rats with unilateral 6-hydroxydopamine lesions of the medial forebrain bundle was investigated, by ...

Minimally Invasive Delivery of Optical Nanosensors Using Injectable Hydrogels

Advanced Materials Interfaces, EarlyView.
Injectable peptide hydrogels offer a minimally invasive delivery platform for single‐walled carbon nanotube (SWCNT)‐based near‐infrared fluorescent sensors, enabling real‐time measurement of drug concentrations. Encapsulated SWCNTs show a dose‐dependent fluorescence response across physiologically relevant concentrations and retain their fluorescence ...

Turning Water Into a Tool: From Degradation Pathways to Functional Engineering in Halide Perovskites

Advanced Materials Technologies, EarlyView.
Water exhibits a threshold‐dependent dual role in lead halide perovskites, acting either as a degradation trigger or as a powerful tool for defect passivation, recrystallization, and structural engineering. This review discusses how controlled water‐mediated interactions govern stability, dimensionality, and optoelectronic performance, providing ...

Isolation of 3,4-dihydroxyphenylalanine-containing proteins using boronate affinity chromatography

, 1986
A rapid procedure for the isolation of 3,4-dihydroxyphenylalanine-containing proteins has been developed in which the protein is selectively bound to a m-phenylboronate agarose column, and eluted with 1.0 m ammonium acetate, pH 3.0.
