Atomically precise metal cluster enzymes for pathological tissue regeneration

open access: yesBMEMat, EarlyView.
Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.

Functional copper requirement for catechol oxidase activity in plantation Eucalyptus species

open access: yes, 1999
Copper (Cu) deficiency in eucalypts is associated with tree deformation and reduced wood production from plantations. Presently, diagnosis of the early stages of Cu deficiency is unreliable as critical tissue Cu concentrations for tree growth have not ...

A Mononuclear Scenario for the Copper‐Catalyzed Monooxygenation of Phenolic Substrates

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Whereas a dinuclear pathway applies to the monooxygenation of phenols by the type 3 copper enzyme tyrosinase, a mononuclear pathway has been identified for the same reaction in corresponding small‐molecule systems. DFT calculations of five copper model complexes reveal that the latter mechanism is energetically feasible, identifying all ...

Xanthine Oxidase Inhibition and Anti-LDL Oxidation by Prenylated Isoflavones from Flemingia philippinensis Root

open access: yesMolecules, 2020
Xanthine oxidase is a frontier enzyme to produce oxidants, which leads to inflammation in the blood. Prenylated isoflavones from Flemingia philippinensis were found to display potent inhibition against xanthine oxidase (XO).

Fermentation‐Induced Modulation of Polyphenolic Contents and Medicinal Activities in Annona squamosa Seeds

open access: yesFood Chemistry International, EarlyView.
The study compared the medicinal activities of polyphenols from fermented and unfermented seeds of Annona squamosa. The polyphenols were extracted and subjected to standard analysis. The major phenolic components of the fermented polyphenols and the unfermented polyphenols were found to be 4‐hydroxybenzoic and 4‐hydroxyphenylacetic acid, respectively ...

Integrated one‐pot CRISPR‐Cas detection: Addressing strategies and future prospects

open access: yesInterdisciplinary Medicine, EarlyView.
Integrated one‐pot CRISPR‐Cas detection significantly simplifies workflows, reduces cross‐contamination risks, and shortens turnaround times, making it highly suitable for point‐of‐care testing (POCT) and resource‐limited settings. Key challenges include system compatibility issues between Cas proteins and isothermal amplification, limited multiplexing

Cultivar affects browning susceptibility of freshly cut star fruit slices

open access: yesScientia Agricola, 2006
Consumption of freshly-cut horticultural products has increased in the last few years. The principal restraint to using freshly-cut carambola is its susceptibility to tissue-browning, due to polyphenol oxidase-mediated oxidation of phenolic compounds ...

Soil Response to Agricultural Land Abandonment: A Case Study of a Vineyard in Northern Italy

open access: yesAgronomy, 2021
Agricultural land abandonment is an emerging problem in European Union (EU), and about 11% of agricultural EU land is at high risk of abandonment in the coming 10 years. Land abandonment may have both positive and negative effects in ecosystems.
