Addressing false negatives and positives in eDNA studies

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental DNA (eDNA) has revolutionized the study of ecology and biodiversity, enabling species detection without direct observation in the environment. However, the implications of detection errors, specifically false positives and false negatives, are poorly reported in eDNA studies, significantly hindering our understanding of the ...

The toxicity of the quaternary ammonium compound benzalkonium chloride alone and in mixtures with other anionic compounds to bacteria in test systems with Vibrio fischeri and Pseudomonas putida

Ecotoxicology and Environmental Safety, 2008
Mixtures of chemicals are present in the aquatic environment but standard testing methods assess only single compounds. One aspect of this question is the importance of the formation of ionic pairs, for example from quaternary ammonium compounds with organic anions, and the significance of the ionic pairs for bacterial toxicity in the aquatic ...

The Efficacy of Nano Silver Sulfadiazine and Nano Benzalkonium Chloride on Heterotrophic Biofilms

, 2019
Silver sulfadiazine and benzalkonium chloride are biocidal agents known to be effective against microorganisms. Although planktonic cells are easily affected by these agents, bacteria in the biofilm layer are more resistant to the same chemicals.

Hypersensitivity to Excipients in Drugs: An EAACI Position Paper

Allergy, EarlyView.
ABSTRACT Drugs contain active pharmaceutical ingredients and excipients, compounds which enhance the pharmacokinetics, stability and palatability of the pharmaceutical formulation. While most drug hypersensitivity reactions (DHR) are caused by active ingredients, excipients may also be involved.
