Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

open access: yesThe Chemical Record, EarlyView.
This review provides a comprehensive and critical analysis of low‐impact synthetic methodologies reported in the last 8 years (2018–2026) for the construction of benzopyran‐derived scaffolds, such as coumarins, flavones, chromones, chromenes, and chromanes. The benzopyran scaffold is a versatile family of heterocycles found in a wide range of bioactive

Genome Sequence and Characterization of Bacillus cereus Endophytes Isolated from the Alectra sessiliflora and Their Biotechnological Potential

open access: yesMicrobiology Research
Bacillus cereus AS_3 and Bacillus cereus AS_5 are bacterial endophytes isolated from sterilized leaves of the medical plant Alectra sessiliflora, which were previously identified using 16S rRNA sequencing. Here, we present the whole-genome sequencing and

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.

Route‐Dependent Toxicity and Ecological Selectivity of Melaleuca alternifolia Essential Oil in Apis mellifera Linnaeus, 1758 (Hymenoptera: Apidae)

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The intensification of agricultural practices has led to an increase in the use of insecticides, raising concerns about the exposure of non‐target organisms, particularly pollinators. In this context, plant‐derived essential oils have been proposed as environmentally friendlier alternatives due to their low persistence; however, their ...

An emetic Bacillus cereus outbreak in a kindergarten: detection and quantification of critical levels of cereulide toxin.

open access: yes, 2015
<p>A Bacillus cereus-related emetic outbreak was reported in a Belgian kindergarten. High levels of emetic B. cereus (>1.5E+07 colony-forming units/g) were detected in the food leftovers, and the presence of an emetic strain was confirmed in ...

Crystal structure of human NIF3‐like protein reveals dynamic hexameric assembly with a single divalent metal binding site

open access: yesThe FEBS Journal, EarlyView.
We present the first crystal structures of human NIF3, revealing a dynamic, hexameric ring with a central cavity regulated by flexible insertion domains. Crucially, human NIF3 features a mononuclear zinc‐binding site, marking a distinct evolutionary departure from the dinuclear centers of bacterial homologs.

Postoperative Antibiotic Duration and Treatment Failure After Aseptic Revision Arthroplasty With a Single Unexpected Positive Culture: A Retrospective Cohort Study

open access: yesOrthopaedic Surgery, EarlyView.
Prolonged postoperative antibiotic use was associated with higher treatment failure in aseptic revision arthroplasty with a single unexpected positive culture, suggesting that extended antibiotic therapy may not improve outcomes and highlighting the need for individualized treatment strategies.
