Titanium Detected in Liver, Kidney, Spleen, and Intestine Is Not Related to Dose, Time, or Route of Exposure to Titanium Dioxide: A Systematic Review

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Titanium dioxide (TiO2), used as a food additive (labeled E171 in Europe), was withdrawn from the European market in 2022. The E171 toxicity mechanism involves its uptake, oxidative stress, DNA damage, and inflammation. It has been hypothesized that the TiO2 accumulation nanoparticles (NPs) or E171 triggers tissue damage, and some studies have

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Inhibition of kynurenine 3‐monooxygenase (KMO) reduces fentanyl and sucrose intake and relapse‐like behaviour in rats

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Opioid use disorder, particularly involving fentanyl, poses major challenges due to high relapse rates and limited effectiveness of pharmacotherapies. The kynurenine pathway has emerged as a target for addiction treatment through its modulation of glutamatergic and dopaminergic neurotransmission.

Oxytetracycline as an otolith chemical marker in Atlantic bluefin tuna (Thunnus thynnus): Technical feasibility in culture

open access: yesJournal of Fish Biology, EarlyView.
Abstract Reliable discrimination between wild and cultured fish is essential for traceability in aquaculture. This study reports the first successful application of intramuscular oxytetracycline (OTC) injection for otolith marking in juveniles of Atlantic bluefin tuna (Thunnus thynnus).

Volatile Organic Compounds Emitted by Fungi Have Substantial Effects on Growth and Disease Resistance in Arabidopsis thaliana

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Volatile organic compounds (VOCs) emitted by certain fungi have previously been suggested to modulate plant development and their response to stresses. While some fungal species, such as Trichoderma harzianum, are known to produce VOCs, the production of VOCs in other phylogenetically divergent species, such as Mucor mucedo, was previously ...

Blubber Cellular Integrity Through Decomposition and Its Implication for Histological Applications: A Study of Stranded Stock A Humpback Whales (Megaptera novaeangliae)

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Marine mammal strandings can provide unique and valuable insights into individual and population health, ranging from infectious diseases to anthropogenic threats. However, the level of decomposition of carcasses can interfere with the assessment of important indicators, such as an individual's nutritional status.

Thrombospondin‐4 is upregulated in abdominal aortic aneurysm: A vasoprotective response with potential therapeutic relevance

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 12, Page 3321-3339, June 2026.
TSP4 is upregulated in human and experimental AAA. TSP4 knockdown accelerated AAA formation and exacerbated both vascular inflammation and remodelling, emphasizing that TSP4 upregulation may represent a protective response against AAA. Our findings suggest that preserving TSP4 could be a useful strategy in the clinical management of AAA.
