The Amidella clade in Europe (Basidiomycota: Amanitaceae): clarification of the...

The species in Amanita ser. Amidella (E.-J.Gilbert) Neville & Poumarat form a well-defined clade, but some taxa remain difficult to discriminate. In particular, the concept of Amanita valens (E.-J.Gilbert) Bertault remains controversial. To understand the phylogenetic placement of a set of collections from southern Portugal with a novel nrDNA barcode, we have obtained nrDNA sequences for previously unassessed t...

Bacterial contamination of the anesthesia breathing machine: effectiveness of c...

Background Bacterial contamination of anesthesia breathing machines and its potential hazard for anesthetized patients have been a concern for many decades. Bacterial filters are effective in preventing breathing circuit contamination but clear recommendations about their use are lacking. The objective of this study is to verify whether the current infection control standards for the operating theater at our in...

Exploring the antioxidant, anti-inflammatory and antiallergic potential of Braz...

Propolis is a bee product used since ancient times due to its diverse biological applications. We aimed to investigate the antioxidant and anti-inflammatory action of Brazilian propolis in THP-1 cells stimulated with 1‐fluoro‐2,4‐dinitrobenzene (DNFB) or lipopolysaccharide (LPS). Methods: Cell viability was assessed by resazurin assay, antioxidant activity was evaluated by DPPH assay, superoxide dismutase (SOD)...

First outbreak of NDM-1-producing Klebsiella pneumoniae ST11 in a Portuguese ho...

New Delhi metallo-β-lactamase (NDM) carbapenemase has been considered a global threat due to its worldwide widespread in recent years. In Portugal, a very low number of infections with NDM-producing Enterobacterales has been reported. A total of 52 strains from 40 patients and 1 environmental sample isolated during COVID-19 pandemic were included in this study. Wholegenome sequencing (WGS) was performed on 20 c...

Invented spelling intervention programmes: Comparing explicit and implicit inst...

This study aims to compare the effectiveness of two invented spelling intervention programs, one with explicit instruction of graph-phonetics matches and another based on questioning and reflection on the graph-phonetic correspondences (implicit instructions). Ninety pre-school children, whose invented spellings use conventional letters unconventionally to represent sounds, were allocated to three groups, two e...
