Toward a Plastic-Free World: Antecedents of Consumer Purchase Intentions and Their Relationship With Purchasing Behavior for Plastic-Free Fresh Products
Consumer preferences for convenience and durability have historically driven demand for plastic-packaged products. However, increasing environmental awareness has spotlighted pro-environmental behaviors like purchasing ...
Validation of a large volume-solid phase extraction methodology for biotoxicity assessment of pharmaceuticals in aquatic organisms
The growing scarcity of freshwater has intensified the need for alternative water sources, which often require advanced treatments to eliminate contaminants. Among emerging pollutants, pharmaceuticals have become a significant ...
Non-target metabolomic approach of the toxic effects of glyphosate in zebrafish (D. rerio)
Glyphosate (GLY) is the most widely used herbicide globally and is frequently detected in aquatic environments at low concentrations, raising concerns about its potential long-term effects on non-target organisms. However, ...
Analytical study, environmental risk assessment, and toxicity-based bioassays of effluents from phosphate fertilizer industry: a case study in Gafsa mining basin (SW Tunisia)
The phosphate fertilizer industry (PFI) in M’dhilla-Gafsa, Tunisia, discharges untreated effluents, creating environmental concerns due to unknown composition and toxic effects, leading to potential ecological and human ...
Alterations in topology, cost, and dynamics of gamma-band EEG functional networks in a preclinical model of traumatic brain injury
Traumatic brain injury (TBI) is a major cause of disability leading to multiple sequelae in cognitive, sensory, and physical domains, including posttraumatic epilepsy. Despite extensive research, our understanding of its ...
Polymeric nanoparticles for liver-targeted pituitary tumor-transforming gene 1 silencing in rats with chronic liver disease
Pituitary tumor transforming gene 1 (Pttg1) is upregulated in cirrhosis and hepatocarcinoma (HCC). We assessed the therapeutic effect of liver-targeted Pttg1 siRNA Retinol (Ret) pBAE nanoparticles (NPs) to treat these ...
The relevance of leader–member exchange during a crisis: assessing the mediating role of social exchange relationships to predict intention to leave
Purpose: The purpose of this study is to explore how the strength of relations between organization, leader and nursing staff influences the intention to leave one’s job during crisis conditions. Drawing on social exchange ...
Compatibility and Physico-Chemical Stability of Six Intravenous Mixtures for Postoperative Multimodal Analgesia
