Malaria mosquito antimicrobial defence requires immunity and detoxification gene regulation by Lola

Insect Molecular Biology, Volume 35, Issue 5, Page 576-593, October 2026.
Malaria mosquito antimicrobial defence requires upregulation of lola. Attenuation of lola in the midgut of Anopheles albimanus mosquitoes inhibits the upregulation of immunity genes induced by challenge. Putative target genes of the Lola transcription factor were revealed by lola attenuation, including Cecropin‐C, Draper, PPAF2, Clip‐domain serine ...

Abrupt Recent Increases in Plastic Ingestion by Sable Shearwaters (Ardenna carneipes)

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract The world is a complex system with rapid changes making it difficult to anticipate further change and mitigate the impacts. Long‐term ecological studies have contributed disproportionately to our understanding of complex ecosystem responses, including shifts in baseline conditions.

New Insights into the Mucus-Secreting Cells in the Proventriculus of 10 Day Old Ross 308 Broiler Chickens—A Qualitative RGB Color Study by Histochemical Assessment

Life
The proventriculus has an important adjustment function in broiler chickens, potentially impacting nutrient availability and performance. Given their contribution to protecting the gastric lining and facilitating digestion, the understanding of the mucus

Modulatory Impacts of Probiotic on the Synthesis of Claudins and Mucins in the Gastrointestinal Tract of Broiler Chicks [PDF]

Brazilian Journal of Poultry Science
This study investigated the effect of 3 strains of probiotic bacteria on mRNA synthesis of some claudins (claudins1(CLD1), CLD3, and CLD5), and mucins (MUC5AC and MUC2) in broilers’ digestive systems.

Assessment of the feed additive consisting of lasalocid A sodium (Avatec® 150G) for turkeys, pheasants, guinea fowl, quails and partridges except laying birds thereof for the renewal of its authorisation (Zoetis Belgium SA)

EFSA Journal, Volume 24, Issue 8, August 2026.
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of lasalocid A sodium (Avatec® 150G) as a coccidiostat for turkeys, pheasants, guinea fowl, quails and partridges. The additive currently on the market complies with the existing conditions of authorisation.

Effects of Cholinergic and Opioid Antagonists on In Vitro Release of Met-Enkephalin, Somatostatin and Insulin-like Growth Factor-1 by and PENK Expression in Crop, Proventriculus and Duodenum of Newly Hatched Chickens

Animals
The gastrointestinal (GI) tract is under neural, endocrine and paracrine control. The release (basal and in the presence of either cholinergic and opioid antagonists) of Met-enkephalin, insulin-like growth factor 1 (IGF-1) and somatostatin (SRIF) was ...

Caenorhabditis elegans and Drosophila melanogaster as Model Organisms in Biofactor Research

BioFactors, Volume 52, Issue 4, July/August 2026.
This review presents Caenorhabditis elegans and Drosophila melanogaster as powerful and ethically sound invertebrate model organisms that can be used to investigate nutritional science questions relating to biofactors. Such nutritional phenotyping studies can bridge the gap between in vitro studies and in vivo research in mammals.
