Advancing plastic pollution hotspotting at the subnational level: Brazil as a case study in the Global South.

Identifying sources is crucial for proposing effective actions to combat marine litter pollution. Here, we used an innovative approach to identify hotspots of mismanaged plastic waste (MPW) within Brazil and subsequent leakage to the ocean, based on population density, socio-economic conditions, municipal solid waste management and environmental parameters. We estimated plastic waste generation and MPW for each of the 5570 Brazilian municipalities, which totaled 3.

How far are we from robust estimates of plastic litter leakage to the environment?

Litter pollution is a global concern, and identifying sources and pathways is crucial for proposing preventative actions. Existing models of plastic litter leakage to the environment have provided worldwide estimates at a country-based level, but only a few initiatives address subnational scales. Adding relevant parameters and improving models is needed to reduce the limitations of global estimates.

Analysis of Cryptococcal Extracellular Vesicles: Experimental Approaches for Studying Their Diversity Among Multiple Isolates, Kinetics of Production, Methods of Separation, and Detection in Cultures of Titan Cells.

Extracellular vesicles (EVs) produced by members of the Cryptococcus genus are associated with fundamental processes of fungal physiology and virulence. However, several questions about the properties of cryptococcal EVs remain unanswered, mostly because of technical limitations. We recently described a fast and efficient protocol of high-yield EV isolation from solid medium.

Population genomic analysis of Cryptococcus Brazilian isolates reveals an African type subclade distribution.

The genomes of a large number of Cryptococcus neoformans isolates have been sequenced and analyzed in recent years. These genomes have been used to understand the global population structure of this opportunistic pathogen. However, only a small number of South American isolates have been considered in these studies, and the population structure of C.
