Air quality can be altered by fungal contaminants suspended in the air, forming bioaerosols. section series are recurrent in bioaerosols and are mainly responsible for allergies and asthma aggravation. Phylogenetic studies recently identified 12 new species within this series.

Article Synopsis
  • - The study explores the pulmonary vascular obstruction index (PVOI) in patients with pulmonary embolism (PE) and evaluates three segmentation methods for quantifying PVOI using perfusion SPECT/CT imaging, aiming to find a reliable automatic approach.
  • - Researchers simulated 396 SPECT/CT scans with varying PE scenarios and tested three methods: intensity threshold (MaxTh), Z-score threshold (ZTh), and relative difference threshold (RelDiffTh) to assess their accuracy in measuring PVOI.
  • - Results indicated that the RelDiffTh method showed the highest mean DICE index (0.85), demonstrating better performance compared to the MaxTh (0.78) and ZTh (0.67)

Trace metal contamination is a widespread and complex environmental problem. Because fungi are capable of growing in adverse environments, several fungal species could have an interesting potential in remediation technologies for metal contaminated environments. This study proposes to test the ability to tolerate and biosorb three trace metals (Cd, Cu and Pb) of 28 fungal isolates collected from different soils.

Background: Inonotus obliquus, also known as Chaga, is a parasitic fungus growing on birches and used in traditional medicine (especially by Khanty people) to treat various health problems. In this study, we aimed to quantify the 3 metabolites frequently cited in literature, that is, betulin, betulinic acid, and inotodiol in the Chaga recently discovered in forests located in Normandy (France), and to compare their concentrations with Ukrainian and Canadian Chaga. This study also explores the cytotoxicity of the French Chaga against cancer-derived cells and transformed cells.
