Effects of essential amino acids on phagostimulation and reproduction in adults of the Mediterranean fruit fly Efectos de amino ácidos esenciales en la fago‐estimulación y reproducción en adultos de la mosca de las frutas del Mediterráneo

Physiological Entomology, EarlyView.
The phagostimulation and reproductive effects of individual essential amino acids, without other nutrient except fructose, were investigated. Methionine, Arginine and Leucine display significantly higher phagostimulation strength than fructose. Arginine and Methionine showed a significant improvement in reproductive activity compared to other tested ...

Restoring the Deformed Administrative State? Bureaucratic Repair After Illiberal Rule

Public Administration Review, EarlyView.
ABSTRACT While scholarship has documented how populist and authoritarian‐leaning executives deform bureaucratic institutions, post‐illiberal reconstruction has only begun to receive attention. This paper develops an exploratory framework distinguishing four repair strategies (neutralizing, rectifying, balancing, and democratic hardening) and two repair

Determination of Exchangeable and Easily Reducible Manganese in Soil by ICP-OES with Ammonium Chloride Extraction

Yankuang ceshi
Manganese is an essential and important mineral element for plants. The content of available manganese in soil is very beneficial to plant growth. Exchangeable manganese (ExMn) and easily reducible manganese (RMn) are the two most important forms of ...

Structure of outer membrane protein G in lipid bilayers

Nature Communications, 2017
Porins, like OmpG, are embedded in the outer membrane of bacteria and facilitate uptake and secretion of nutrients and ions. Here the authors present a protocol for solid state NMR structure determination of proteins larger than 25 kDa and use it to ...

Neurons differentially upregulate type 2 immune cytokines and interleukin-4 receptor subtypes during neuroinflammation

Acta Neuropathologica Communications
Although numerous studies demonstrate beneficial effects of exogenous interleukin-4 (IL-4) in different central nervous system (CNS) disease models, little is known about the expression of IL-4 and its receptor (IL-4R) system in neurons.

Accelerating Polyester Melt Polycondensation Through Devolatilization Regulated by Disk Openings in a Horizontal Disk Reactor

Advanced Chemical Engineering, Volume 1, Issue 2, December 2026.
Disk openings regulate devolatilization during horizontal melt polycondensation. In polyethylene naphthalate, a four‐opening disk maximizes the apparent EG volumetric mass‐transfer coefficient and aligns EG removal with its generation, shifting equilibrium forward.

Analyse par RMN

, 2009
Deux cas d'intoxication volontaire par un herbicide sont rapportés chez deux hommes de 51 et 52 ans. L'analyse par spectroscopie RMN-1H du désherbant a permis de montrer qu'il contenait essentiellement deux herbicides chlorophénoxylés : l'acide 2-(2 ...

Sequential domain assembly of ribosomal protein S3 drives 40S subunit maturation

Nature Communications, 2016
Ribosome biogenesis involves the hierarchical assembly of several proteins and RNA components. Here the authors describe a mechanism for ribosomal protein S3 incorporation into 40S ribosomal subunits that involves S3 dimerization and stepwise ...

Long‐Time Thermal Aging of Perfluoroalkoxy Polymers for Electrical Insulation: Structural and Physical Properties Evolutions

Journal of Applied Polymer Science, Volume 143, Issue 39, October 15, 2026.
This work focuses on the investigation of the influence of a long‐time exposition to accelerated thermal aging on the physicochemical structure and properties of PFA. Results show a decrease in the melting temperature and crystal ratio due to chemical aging.
