Key Role of Water-Insoluble Allergens of Pollen Cytoplasmic Granules in Biased Allergic Response in a Rat Model

World Allergy Organization Journal, 2011
Background Grass pollen grain, an important aeroallergen, can disperse in the environment pollen cytoplasmic granules (PCGs) able to release water-soluble allergens when they are washed out by rainfall. The allergenicity of these washed PCGs is, however,

Glyco‐Nanogels for Modulating Pseudomonas aeruginosa Biofilm

Macromolecular Rapid Communications, EarlyView.
Nanogels presenting α‐galactose and β‐fucose can significantly alter Pseudomonas aeruginosa biofilm dynamics through their interaction with lectins. Application timing is crucial: pre‐treatment reduces biofilm, while treatment after biofilm initiation increases biomass.

Utilizing Lightweight Expanded Clay Aggregate as Coarse Aggregate in Concrete [PDF]

E3S Web of Conferences
In recent years, the need for sustainable building materials has encouraged the use of lightweight concrete (LWC), as it offers advantages such as reduced dead load, improved workability and enhanced environmental efficiency. In this work, the mechanical

A genomic amplification affecting a carboxylesterase gene cluster confers organophosphate resistance in the mosquito Aedes aegypti: From genomic characterization to high‐throughput field detection

Evolutionary Applications, 2021
By altering gene expression and creating paralogs, genomic amplifications represent a key component of short‐term adaptive processes. In insects, the use of insecticides can select gene amplifications causing an increased expression of detoxification ...

Realizing a Regenerative Future by Revisiting Our Roots: A Dialectical Model of Management for the Circular Economy

British Journal of Management, EarlyView.
Abstract The circular economy (CE) is often treated as a technological or system‐design challenge. We argue that it is also a managerial transition that remains under‐theorized. Rather than assuming that CE requires wholly new managerial frameworks, we revisit Fayol's functions of planning, organizing, leading and controlling as enduring managerial ...

CH−π “T-Shape” Interaction with Histidine Explains Binding of Aromatic Galactosides to Pseudomonas aeruginosa Lectin LecA

, 2013
The galactose specific lectin LecA mediates biofilm formation in the opportunistic pathogen P. aeruginosa . The interaction between LecA and aromatic β-galactoside biofilm inhibitors involves an intermolecular CH-π T-shape interaction between C ...

Experimental evolution supports the potential of neonicotinoid-pyrethroid combination for managing insecticide resistance in malaria vectors

Scientific Reports, 2021
The introduction of neonicotinoids for managing insecticide resistance in mosquitoes is of high interest as they interact with a biochemical target not previously used in public health.

Key agroecosystems for the conservation of amphibians and reptiles in Europe

Conservation Biology, EarlyView.
Abstract Agricultural expansion and intensification are driving amphibian and reptile declines worldwide. However, sustainably managed agroecosystems can support a high diversity of herpetofauna, which play a key role in pest control, reducing crop damage.
