Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.Nano‐immunostimulants improve fish health through targeted and controlled delivery of immunostimulatory compounds. Biodegradable polymeric and lipid‐based nanocarriers enhance immune responses, bioavailability and disease resistance while reducing antibiotic dependence and environmental impact.

Acta Agriculturae Slovenica, 2019 This study investigated the effect of Teucrium polium L. essential oil (Tp EO) and α-pinene as its major component on the detoxifying- and intermediary-engaged enzymes of Ephestia kuehniella Zeller. Fourth instar larvae were separately fed on the treated

Functional Ecology, Volume 40, Issue 9, Page 2982-3000, September 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The impacts of elevated surface ultraviolet‐B (UV‐B) on ecological processes, such as anti‐herbivore defence in plants, remain poorly understood. Many cereal crops depend on accumulating silicon (Si) in their tissues to resist insect herbivory.

The Phenoloxidase Activity in Prawn Hemocytes.
Fish Pathology, 1992 1. クルマエビ血液中のフェノールオキシダーゼ (PO) 活性の分布を調べるために, 血漿成分と血球成分のPO活性を測定した。その結果, 血漿ならびに血球成分ともにPO活性が認められたが, とりわけ血球中の活性が高かった。2. クルマエビ血球成分中のPO活性の酵素化学的性状について検討した結果, PO活性の反応至適温度は40℃であり, 熱処理または0.5M以上の条件下において著しい活性の低下がみられた。また, 活性はEDTAにより阻害されたが, EGTAによる阻害性は低く, Caイオン依存性ではなかった。3. PO活性はPMSFやDEDTによって阻害されたことから, 活性の反応系にはセリンプロテアーゼや銅酵素の関与が示唆された。

Ecology and Evolution, Volume 16, Issue 8, August 2026.We show that temperature and solar radiation shape insect community traits in scale‐dependent ways across German forests. Whereas macroclimatic temperature predicts consistent shifts in body size and colouration, microclimatic variation driven by canopy structure can override these broad patterns, producing contrasting trait filtering among taxa ...

Ecology and Evolution, Volume 16, Issue 8, August 2026.We highlight the importance of considering insecticide effects on trait variance and selection—not merely trait means—to fully understand evolutionary changes in non‐target populations. We suggest incorporating sublethal effects on semi‐aquatic predatory insects into ecological risk assessments on agroecosystems. ABSTRACT Agricultural insecticides pose

Soluble peroxidase from winter wheat seedlings with phenoloxidase-like activity.
, 1990 Peroxidase isozymes from winter wheat (Triticum aestivum L. cv Orso) seedlings extracts showed phenoloxidase-like activity, becoming visible on polyacrylamide gels also in the absence of hydrogen peroxide. The results obtained after a characterization

곤충의 Pro-Phenoloxidase-Activating System에 관여하는 효소들의 대장균내 발현
, 2000 학위논문(석사) - 한국과학기술원 : 화학과, 2000.2, [ iv, 35 p. ]The pro-phenoloxidase activating system plays an important role in a defensive reaction in insects. Phenoloxidase (PO) that is generated from pro-phenoloxidase (pro-PO) by the pro-PO-activating system ...
