Cyanobacterium Brasilonema sp. LPS Induces Neutrophil Infiltration and Lung Inflammation in a TLR4-Dependent Manner and Exacerbates Th2-Dependent Lung Inflammation. [PDF]

Immun Inflamm Dis
ABSTRACT Background Chronic airway inflammation can be induced by both chemical and environmental factors. Airway inflammation can be induced through different immune pathways, including allergic Th2‐dependent activation of eosinophils and mast cells, Th1/Th17‐dependent neutrophil recruitment, or a combination of both mast cell and neutrophil ...

MALDI-TOF mass spectrometry of Cyanobacteria: a global approach to the discovery of novel secondary metabolites [PDF]

, 2008
Cyanobacteria (blue-green algae) are a group of ancient prokaryotic organisms dating back between three and four billion years.¹ They have been attributed with oxygenating the earth’s atmosphere² but, since the anthropogenic euthrophication of lakes ...

Cyanobacterial blooms [PDF]

, 2018
Cyanobacteria can form dense and sometimes toxic blooms in freshwater and marine environments, which threaten ecosystem functioning and degrade water quality for recreation, drinking water, fisheries and human health.

C‐Terminal Functionalization Methods of Amino Acids, Peptides, and Proteins

Chemistry – A European Journal, EarlyView.
C‐terminal functionalization offers powerful routes to peptide and protein diversification, yet epimerization, hydrolysis, and selectivity remain key challenges. This Review surveys enzymatic, decarboxylative, and condensation strategies, highlighting advances toward chemo‐ and regioselective, protecting‐group‐free, atom‐efficient methods applicable to

Effects of Glyphosate and Glyphosate‐Based Herbicides on the Mammalian Gut Microbiome: A Critical Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Glyphosate has long been considered to pose negligible direct risk to mammals on the grounds that its molecular target, 5‐enolpyruvylshikimate‐3‐phosphate synthase (EPSPS), of the shikimate pathway, is absent from animal cells. This rationale is inaccurate as a complete toxicological argument, because the shikimate pathway is present in some ...

Structural Diversity of Bacterial Communities Associated with Bloom-Forming Freshwater Cyanobacteria Differs According to the Cyanobacterial Genus. [PDF]

PLoS ONE, 2015
The factors and processes driving cyanobacterial blooms in eutrophic freshwater ecosystems have been extensively studied in the past decade. A growing number of these studies concern the direct or indirect interactions between cyanobacteria and ...

Responses of primary producers, anoxia, and chemical feedback to Late Glacial climate change: Insights from a paired lake approach

Journal of Quaternary Science, EarlyView.
Abstract Worldwide, lacustrine ecosystems are threatened by eutrophication and deoxygenation. Both processes are driven by the combined effects of human activities and climate change. Understanding the pre‐anthropogenic nexus between warming, eutrophication, deoxygenation, and related feedback is essential to determine how lakes respond to rapid ...
