Green synthesis of silver nanoparticles (AgNP) has been proposed as a safer and more sustainable alternative for AgNP production. However, limited information exists on the toxicity mechanisms and accumulation of green -synthesized AgNP. In this study, we used AgNP synthesized with Amazonian açaí (Bio-AgNP) to evaluate their accumulation and biochemical effects in Caenorhabditis elegans . Bio-AgNP were synthesized using aqueou...

Caenorhabditis elegans is widely used in nanotoxicology studies involving silver nanoparticles (AgNP). However, variations in test media composition can influence AgNP toxicity in worms, complicating cross-study comparisons. This study evaluated the effects of six commonly used media: M9 buffer, K-medium, S-basal, EPA water, Nematode Growth Medium agar (NGM), and “Biofilm” (a combination of NGM and EPA water) on biological res...

Background Ulcerative colitis (UC) is a chronic inflammatory disease that is increasing in prevalence worldwide. Notably, helminth infections, known for their immunoregulatory properties, are inversely related to inflammatory conditions such as UC. Research has indicated that Taenia crassiceps infection can improve inflammatory-mediated diseases, including type 1 diabetes, experimental autoimmune encephalomyelitis, and colitis...

The disruption of vehicle traffic on important transport infrastructure has a major economic impact. Therefore, the instability of highway cut-slopes poses a significant risk for major infrastructures crossing mountainous regions and rocky coasts. The use of Uncrewed Aerial Vehicles (UAVs) is of great help in the prevention of road cut-slope failures and in emergency and rehabilitation of sites impacted by this type of landsli...

Intact executive functions are required for proper performance of cognitive tasks and relies on balance of excitatory and inhibitory (E/I) transmission in the medial prefrontal cortex (mPFC). Hypofrontality is a state of decreased activity in the mPFC and is seen in several neuropsychiatric conditions, including substance use disorders. People who chronically use methamphetamine (meth) develop hypofrontality and concurrent cha...

Marine kelp forests cover 1/3 of our world's coastlines, are heralded as a nature-based solution to address socio-environmental issues, connect hundreds of millions of people with the ocean, and support a rich web of biodiversity throughout our oceans. But they are increasingly threatened with some areas reporting over 90% declines in kelp forest cover in living memory. Despite their importance and the threats they face, kelp...

A mass mortality event (MME) affecting the fan mussel Pinna nobilis was first detected in Spain in autumn 2016 and spread north- and eastward through the Mediterranean Sea. Various pathogens have been blamed for contributing to the MME, with emphasis in Haplosporidium pinnae , Mycobacterium sp. and Vibrio spp. In this study, samples from 762 fan mussels (necropsies from 263 individuals, mantle biopsies from 499) of various hea...

To determine the drivers of phytoplankton biomass, we collected standardized morphometric, physical, and biological data in 230 lakes across the Mediterranean, Continental, and Boreal climatic zones of the European continent. Multilinear regression models tested on this snapshot of mostly eutrophic lakes (median total phosphorus [TP] = 0.06 and total nitrogen [TN] = 0.7 mg L −1 ), and its subsets (2 depth types and 3 climatic...
