Urbanization and Seasonality Increase Introduced Plant Consumption by the World's Southernmost Parrot 城市化与季节性增加了全球最南端鹦鹉对引入植物的取食

open access: yesIntegrative Conservation, EarlyView.
Urbanization may alter bird foraging. Austral Parakeets (Enicognathus ferrugineus) in Patagonia rely on introduced plants in urban areas, especially in winter, despite preferring natives in the wild. This seasonal reliance on introduced species highlights urbanization trade‐offs and underscores the need to manage green areas with native plants to ...

New Approach Methodologies (NAMs) in Alternative Methods: A Comparative Cytotoxicity Analysis of Nanostructured Hydroxyapatite in Adipose Stem Cells Spheroids

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Toxicological assessment is essential in NP approval for health and medical applications. Although 2D cell culture has been widely used, 3D models, especially spheroids, provide better predictive value for toxicological risk assessments since they replicate complex cellular interactions more accurately.

Subchronic Exposure to Arsenic and Nickel Triggers Nitrosative Stress and Histological Alterations in the Rat Liver

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Environmental exposure to heavy metals poses a threat to human health. Several studies documented harmful effects on the liver after arsenic and nickel exposure at concentrations beyond permissible limits. Nevertheless, the impact of a simultaneous exposure to both elements on hepatic biochemistry and histology remains unelucidated. Therefore,

Evaluating the Air Respiratory Capacity of Awaous (Chonophorus) tajasica (Gobiiformes: Oxudercidae): A Morpho‐Functional Study

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
We demonstrated that Awaous tajasica performs facultative air breathing under experimental conditions of dissolved oxygen limitation, retaining air bubbles in the buccal cavity during gill ventilation. Morpho‐functional evidence indicates the use of atmospheric oxygen as a respiratory support under conditions of low water oxygenation.
