Air pollution is a major environmental risk to public health, strongly associated with cardiovascular and respiratory diseases. According to the World Health Organization, at least 99% of the global population lives in areas that do not meet its air-quality guidelines. PM $$_{2.5}$$ 2.5 variability reflects the interaction between local emission sources and meteorological processes that regulate near-surface dispersion and acc...
Farming-associated variation in chytrid infection and shedding dynamics in invasive American bullfrogsNARA Subscribed
The global amphibian decline caused by the chytrid fungus Batrachochytrium dendrobatidis (Bd) threatens biodiversity. Some species, such as the bullfrog ( Aquarana catesbeiana ), can persist with infection without overt disease, yet the processes underlying this response remain unclear. Because bullfrogs are farmed worldwide under high-density conditions, understanding how production environments influence infection dynamics a...
Methodology for monitoring micropollutants in rivers: a case study from the Upper Cauca River Basin, ColombiaNARA Subscribed
The design of a micropollutant monitoring network in rivers is a challenging task because of the lack of environmental regulations, high laboratory analysis costs, and the limited availability of standardized analytical techniques, especially in Latin America. These constraints hinder the ability to make informed, data-driven decisions. In this study, we proposed a methodology that updates the micropollutant measurement proces...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
Alzheimer’s disease (AD) is characterized by an insidious onset and complex pathophysiology, necessitating the development of effective strategies for early detection and intervention. This exploratory study aimed to identify differentially expressed genes (DEGs) and disrupted molecular pathways in AD by analyzing blood samples from participants recruited in Valle del Cauca, Colombia, a region with high genetic admixture and p...
While T-cell Bispecifics (TCBs) are promising molecules for cancer treatment, their clinical development remains challenging due to Cytokine Release Syndrome (CRS). There is currently no method to accurately predict the doses expected to trigger CRS from pre-clinical data, resulting in the selection of non optimal First-In-Human (FIH) doses, far from the doses expected to show clinical benefit, to address safety concerns. In t...
Our primary objective was to compile a comprehensive dataset on bird–window collisions throughout the Neotropical region, including both published and unpublished sources. On May 12, 2020, we extensively disseminated invitations to provide data via email and social media platforms. By providing a template worksheet, we required standardized information from collaborators to complete and register their data. To better understan...
Human Health Risk Assessment (HHRA) is a widely applied method to make decisions about the environmental status of sites affected by toxic substances. Its conclusions are affected by the variability and uncertainty of the input variables in the HHRA model. The aim of this work is to apply an algorithm based on 2D Monte Carlo simulations to integrate the variability and uncertainty of exposure factors, concentration, and bioacc...
