Biochemical responses of barley seeds to the cumulative effects of treated wastewater irrigation

Treated wastewater (TWW) may still contain residual pollutants and chemicals that can accumulate in plant tissues and seeds, potentially disrupting plant metabolism and physiological processes. In this study, we investigated the cumulative effect of TWW on the primary metabolites...

Camel milk and carob fortified yogurts modulate oxidative stress autophagy and migration in HCT-8 colorectal cancer cells

This study examined the biological activity of camel milk (CM), control yogurt (YC), and carob-fortified yogurts (YPC and YSC) as fermented dairy-based functional formulations, using human colorectal adenocarcinoma HCT-8 cells. Cells were exposed to 10, 25, and 50 µg/mL for 24 h,...

Contrasting Responses of Two Sympatric Canids, the African Golden Wolf and Red Fox, to Anthropogenic and Habitat Related Factors in Arid Landscapes of Southern Tunisia

ABSTRACT Human‐induced landscape changes increasingly shape the spatial ecology of wildlife, particularly in arid ecosystems where resources are limited. This study investigates how the combined effects of anthropogenic pressures and prey availability influence the distribution a...

International Migration, Remittances, Climate Change Adaptation Practices, and Agricultural Sustainability in Coastal Oases (Southeastern Tunisia)

In the arid regions of southeastern Tunisia, international migration—often driven by declining agricultural yields due to climate change—can be associated with strengthening the resilience of agro-systems through the valorization of migratory assets, particularly remittances inve...

Hybrid chemical-biogenic synthesis of silver nanoparticles with antibacterial efficacy using Salicornia and Sarcocornia hydroethanolic extracts

This study investigates the use of a hybrid approach combining various ratios of sodium borohydride (NaBH4) with hydroethanolic extracts of Salicornia emerici, Sarcocornia fruticosa, and Sarcocornia alpini as reducing agents for AgNPs synthesis. The resulting nanoparticles were c...
