Juvenile and Pubertal Exposure to Polystyrene Nanoplastics Impairs Epididymal Structure and Sperm Quality in Mice

Environmental Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are emerging environmental contaminants capable of crossing biological barriers, accumulating in tissues, and disrupting physiological pathways. The male reproductive system is particularly vulnerable during the postnatal period, a developmental window characterized by intense testicular differentiation and epididymal ...

A multiplex assay to detect mosquito species, bloodmeal host source and Plasmodium in malaria vectors using Nanopore amplicon sequencing

Medical and Veterinary Entomology, Volume 40, Issue 3, Page 465-477, September 2026.
Insectary‐reared mosquitoes were simultaneously assessed for species identification, bloodmeal source analysis and Plasmodium detection, using a single multiplexed sequencing run on the MinION sequencing platform. The method was applied to 150 insectary‐reared mosquitoes, representing nine species blood‐fed with five vertebrate hosts and 40 samples for

SARS‐CoV‐2 Spike Peptides Trigger Nociceptive Responses Through Spinal TLR4 Pathways

European Journal of Pain, Volume 30, Issue 7, August 2026.
ABSTRACT Background Pain is a common neurological manifestation of COVID‐19, yet the mechanisms by which SARS‐CoV‐2 spike protein fragments contribute to nociceptive processing remain poorly understood. We investigated whether spike‐derived peptides directly activate spinal neuroimmune pathways involved in pain signalling.

Range extension and first records of Coryphaenoides striaturus Barnard, 1925 and Coryphaenoides subserrulatus Makushok, 1976 (Macrouridae: Gadiformes) in Brazilian waters, Southwest Atlantic, using integrative taxonomy

Journal of Fish Biology, Volume 109, Issue 1, Page 599-604, July 2026.
Abstract Coryphaenoides Gunnerus, 1765 comprises 66 valid species of deep‐sea fishes commonly known as grenadiers, with 6 previously reported from Brazilian waters. Here, we make the first records for Coryphaenoides striaturus and Coryphaenoides subserrulatus on the Brazilian continental slope. Both species are distributed in the subtropical regions of

Rheology–Performance Framework for PA6/GO Nanocomposites via a Hybrid Processing Route

Polymer Engineering &Science, Volume 66, Issue 6, Page 4137-4149, June 2026.
Hybrid PA6/GO nanocomposites with tuned melt rheology and improved thermal–mechanical performance. ABSTRACT Balancing melt processability with stiffness and heat resistance remains a central challenge for PA6 nanocomposites. Here, graphene oxide (GO) was synthesized by a modified Hummers method and incorporated into PA6 via a hybrid route (solution ...

Faunistic inventory of the genus Culicoides (Diptera: Ceratopogonidae) in Mauritius Island, Indian Ocean: Diversity and spatial distribution of species of veterinary interest Inventaire faunistique du genre Culicoides (Diptera: Ceratopogonidae) sur l'île Maurice dans l'océan Indien: diversité et répartition spatiale des espèces présentant un intérêt vétérinaire

Medical and Veterinary Entomology, Volume 40, Issue 2, Page 282-293, June 2026.
Four Afrotropical Culicoides species are recorded in Mauritius with suspected or historically involvement in BTV and EHDV transmission. All species were distributed all over the island. While intra‐specific morphological variations were detected, genetic analyses did not reveal any cryptic diversity. Abstract Viruses transmitted by biting midge species

Foundation Model‐Assisted Segmentation Enables Robust Field‐Based Severity Estimation: A Case‐Study of Coffee Leaf Rust

Plant Pathology, Volume 75, Issue 3, May–June 2026.
Foundation model‐assisted segmentation enables accurate field estimation of coffee leaf rust severity. Using 1285 images and curated lesion masks, we compared SAM3, SAM2, DeepLabV3+ and classical threshold methods. SAM3 achieved the highest segmentation accuracy and best agreement with reference severity, demonstrating reliable, scalable disease ...
