Hydrogen sulphide as a guard cell network regulator
(Wiley Blackwell Publishing, Inc, 2020-11-29)
Hydrogen sulphide (H2S) is an endogenously produced gasotransmitter that has rapidly emerged as an active signalling component of several plant processes, stomatal movement regulation among them. The guard cells (GCs), ...
Hydrogen sulphide, a novel gasotransmitter involved in guard cell signalling
(Wiley, 2010-12)
•Hydrogen sulphide (H2S) has been proposed as the third gasotransmitter. In animal cells, H2S has been implicated in several physiological processes. H2S is endogenously synthesized in both animals and plants by enzymes ...
Circulating levels of hydrogen sulphide negatively correlate to nitrite levels in gestational hypertensive and preeclamptic pregnant women
(2021-09-01)
Endothelial dysfunction is a hallmark of preeclampsia and the role of nitric oxide (NO) has been extensively studied in this pregnancy complication. In recent years, hydrogen sulphide (H2S) has arisen as a new gasotransmitter ...
Performance evaluation of packing materials in the removal of hydrogen sulphide in gas-phase biofilters: Polyurethane foam, sugarcane bagasse, and coconut fibre
(ELSEVIER SCIENCE SA, 2010)
The main objective of this work was to investigate three packing materials (polyurethane foam, sugar-cane bagasse, and coconut fibre) for biofiltration of a gaseous mixture containing hydrogen sulphide (H(2)S). Mixed ...
Inhibition of hydrogen sulphide formation reduces cisplatin-induced renal damage
(OXFORD UNIV PRESS, 2011)
Background. Cisplatin (CP)-induced renal damage is associated with inflammation. Hydrogen sulphide (H(2)S) is involved in models of inflammation. This study evaluates the effect of DL-propargylglycine (PAG), an inhibitor ...
Inhibition of hydrogen sulphide formation reduces cisplatin-induced renal damage
(Oxford Univ Press, 2011-02-01)
Background. Cisplatin (CP)-induced renal damage is associated with inflammation. Hydrogen sulphide (H(2)S) is involved in models of inflammation. This study evaluates the effect of DL-propargylglycine (PAG), an inhibitor ...
Electrochemical production of colloidal sulphur by oxidation of sulphide ion at lead coated-2- and -3-dimensional rotating cylinder anode surfaces
(Pergamon-Elsevier Science Ltd, 2017-07)
An electrochemical reactor with a rotating cylinder electrode is analysed for the production of colloidal sulphur by oxidation of sulphide ions with a concentration of 2 g dm−3 in alkaline solutions at 80 °C. The anode, ...
Increases in placental nitric oxide, but not nitric oxide-mediated relaxation, underlie the improvement in placental efficiency and antihypertensive effects of hydrogen sulphide donor in hypertensive pregnancy
(2018-11-01)
Dysregulation of hydrogen sulphide (H2S) producing enzymes has been related to hypertensive pregnancy, and H2S donor, sodium hydrosulphide (NaHS) exerts antihypertensive effects, modulates angiogenic factors production and ...
Dessulfurização biológica – estudo de caso com microaeração em biodigestor de lagoa coberta
(Universidade Tecnológica Federal do ParanáMedianeiraBrasilTecnologias da Cadeia Produtiva do BiogásUTFPR, 2019-05-04)
Biogas is produced from the anaerobic digestion of different substrates, are composed basically of methane, carbon dioxide, oxygen, hydrogen and hydrogen sulfide. The h2s combined with humidity can cause serious damage to ...
Colloidal sulphur production by electrochemical oxidation of sulphide in a swirling flow reactor
(Royal Society of Chemistry, 2021-10)
A cylindrical reactor with swirling flow is tested for the production of colloidal sulphur via the oxidation of sulphide ions with a concentration of 2 g dm−3 in alkaline solutions at 80 °C. Polysulphides are anodically ...
