Identification and characterisation of the ecdysone biosynthetic genes neverland, disembodied and shade in the salmon louse Lepeophtheirus salmonis (Copepoda, Caligidae). [PDF]

open access: yesPLoS ONE, 2018
The salmon louse is a marine ectoparasitic copepod on salmonid fishes. Its lifecycle consists of eight developmental stages, each separated by a molt. In crustaceans and insects, molting and reproduction is controlled by circulating steroid hormones such

Phytochemical Investigation of Stachys hissarica: Antioxidant Activity, Flavonoid Characterization, and In Silico Analysis

open access: yesChemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Stachys hissarica demonstrates remarkable antioxidant potential, driven by a rich profile of 35 annotated polyphenolic metabolites within its aqueous methanolic extract. Hydrophilic phenolics exhibit superior radical‐scavenging activity comparable to ascorbic acid. Integrated computational simulations reveal favorable oral bioavailability, low toxicity,

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

open access: yesInsect Science, Volume 33, Issue 5, Page 1845-1864, October 2026.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Effects of Different Dietary Levels of Chia (Salvia hispanica L.) and Quinoa (Chenopodium quinoa Willd.) on Adipokines and Anthropometric Parameters in Rats

open access: yesFood Science &Nutrition, Volume 14, Issue 9, September 2026.
Six weeks dietary supplementation with chia (Salvia hispanica L.) and quinoa (Chenopodium quinoa Willd.) modulated adipokine profiles and anthropometric parameters in male Wistar rats: 20% chia and quinoa decreased serum chemerin, resistin, and insulin levels while increasing omentin; 10%–20% supplementation decreased visfatin; all supplemented diets ...

Stage‐Specific H3K14 and H3K23 Succinylation Orchestrates Insect Metamorphosis and Oogenesis

open access: yesAdvanced Science, Volume 13, Issue 43, 3 August 2026.
Stage‐specific succinylation of histone H3 at lysine 14 and 23 differentially controls insect metamorphosis and oogenesis through distinct GPCR‐PKC signaling cascades, revealing an evolutionarily conserved epigenetic mechanism that coordinates key life‐history traits.
