Role of Chitinases in Human Stomach for Chitin Digestion: AMCase in the Gastric Digestion of Chitin and Chit in Gastric Pathologies.

open access: yes, 2009
Chitin-containing food is an interesting but underestimated source of locally available, in most cases sustainable, food although chitin digestion by humans has generally been questioned or denied.

Predator‐associated microbiomes as hidden modulators of pesticide‐compatible biological control in agroecosystems

open access: yesPest Management Science, EarlyView.
Predator‐associated microbiomes influence nutrition, reproduction, behaviour and pesticide tolerance, thereby shaping predator resilience and the reliability of biological control in agroecosystems. Abstract Beneficial arthropod predators are central components of integrated pest management, yet their performance in crop systems is often variable ...

Long‐term impact of exposure to Royal Guard, a pyriproxyfen‐based bed net, on pyrethroid‐resistant malaria vectors from Cameroon using DNA‐based metabolic resistance markers

open access: yesPest Management Science, Volume 81, Issue 4, Page 2165-2180, April 2025.
We used recently detected P450 DNA‐based markers of pyrethroid resistance in both Anopheles funestus and Anopheles gambiae to demonstrate that although pyrethroid‐resistant mosquitoes have higher ability to survive and live longer after exposure to Royal Guard, this net significantly affects their lifespan, blood feeding ability and interestingly ...

Efficient water‐soluble blue/red‐emissive carbon dots matching plant absorption spectra: Synthesis, tunable control, and their applications in promoting plant growth

open access: yesResponsive Materials, EarlyView.
Guided by the spectral demand of plant photosystems, this review summarizes the synthesis, emission regulation, dual‐emission design, and gram‐scale production of CDs for agricultural applications. Spectrally matched blue‐ and red‐emissive CDs enhance plant light utilization by converting underutilized light into photosynthetically active radiation and

Cross‐Scale Engineering of Single‐Atom Catalysts from Local Planar Coordination to Spatial Architectures

open access: yesSmall, EarlyView.
This Review presents a cross‐scale framework for single‐atom catalysts, spanning in‐plane and out‐of‐plane coordination; primary coordination, secondary‐sphere interactions, through‐space microenvironments and support interfaces; individual sites and macroscopic architectures; and static design and directed dynamic reconstruction.

Exploiting Phase Partitioning of a Giant Trimeric Fibrous Protein Scaffold to Potentiate Chitinase‐Driven Antifungal Activity

open access: yesSmall, EarlyView.
Cstalk, a giant fibrous protein, selectively partitions into the dextran‐rich phase in polyethylene glycol/dextran aqueous two‐phase systems, functioning as a recruiter for proteins of interest. This phase‐selective recruitment can be extended to fungal cell walls, enabling the targeted localization of enzymes and enhancing antifungal activity through ...

Bidirectional Plant‐Microneedle Responses to Guide Biomaterial Design

open access: yesSmall, EarlyView.
We examine bidirectional interactions between plants and polymeric microneedles to develop effective compound delivery strategies. Material chemistry and architecture determine stability in the plant environment, cargo–matrix interactions, and the magnitude and duration of the plant response. Plant microneedles should therefore be designed as a coupled

Microwave-based gluconic acid-catalyzed extraction of chitin-glucan extract from industrial Aspergillus niger biomass with functional activities

open access: yesKuwait Journal of Science
Industrial Aspergillus niger biomass can be a valuable source of biopolymers with antioxidative and prebiotic properties. To achieve this proposal, ethanol extraction of soluble free compounds with antioxidant activity was separated from native biomass ...
