Chemical Defence by Sterols in the Freshwater Ciliate Stentor polymorphus. [PDF]

open access: yesBiology (Basel), 2022
Heterotrich ciliates typically retain toxic substances in specialized ejectable organelles, called extrusomes, which are used in predator-prey interactions. In this study, we analysed the chemical defence strategy of the freshwater heterotrich ciliate Stentor polymorphus against the predatory ciliate Coleps hirtus, and the microturbellarian flatworm ...

Costs and benefits of chemical defence in the Red Alga Bonnemaisonia hamifera. [PDF]

open access: yesPLoS ONE, 2013
A number of studies have shown that the production of chemical defences is costly in terrestrial vascular plants. However, these studies do not necessarily reflect the costs of defence production in macroalgae, due to structural and functional ...

Discovery of plant chemical defence mediated by a two-component system involving β-glucosidase in Panax species [PDF]

open access: yesNature Communications
Plants usually produce defence metabolites in non-active forms to minimize the risk of harm to themselves and spatiotemporally activate these defence metabolites upon pathogen attack.

Chemical Defence of a Seagrass against Microfoulers and Its Seasonal Dynamics

open access: yesApplied Sciences, 2019
In marine environments bacterial microfoulers are an important determinant for the settlement of algal and animal macrofoulers. At the same time fouling is usually subject to seasonal fluctuation.

Bile acids in physico-chemical host defence

open access: yesPathophysiology, 2004
The discovery of the physico-chemical host defence is closely connected with the endotoxin research. It is well known that the toxic effects of endotoxins under experimental conditions can be induced only when they are administered parenterally. However, in naturally occurring entero-endotoxemic diseases (e.g.

Pretreatment Method for Peroxides Decon Water Before GC Analysis of HD, VX, and GD [PDF]

open access: yesE3S Web of Conferences, 2021
Peroxides like sodium percarbonate (SPC) and sodium percarbonate-acetylsalicylic acid (SPC-Aspirin) can be used to destroy chemical warfare agents (CWAs) such as HD, VX and GD due to the former's oxidation capacity and nucleophilicity.

Study on Kinetics of GD Hydrolysis in HCl aqueous [PDF]

open access: yesE3S Web of Conferences, 2021
Organophosphate neurotoxic agents like Sarin (GB) and Soman (GD) are lethal to person. Except various kinds of decontaminants, they can be also decomposed in natural environment through nucleophilic reaction, where acidic or alkaline substance was to ...

Study on detoxification property of alkaline-modified MoO42--H2O2 decontaminants against PhSMe under subzero environment [PDF]

open access: yesE3S Web of Conferences, 2021
The decontaminant activated by MoO42- (MoO42--H2O2) suitable for subzero environment shows strong oxidizing ability and weak nucleophilicity due to its acid. In this paper, in order to improve nucleophilicity and retain oxidation of MoO42--H2O2 as far as

Study on catalytic performance of MnOx nanoparticles for CO oxidation [PDF]

open access: yesE3S Web of Conferences, 2021
As a kind of toxic gas, carbon monoxide is often found in industrial waste gas, automobile exhaust, confined space such as submarines, etc. In recent years, the purification of carbon monoxide has attracted more and more attention.
