Cable bacteria delay euxinia and modulate phosphorus release in coastal hypoxic systems
No full textCable bacteria are long, filamentous bacteria with a unique metabolism involving centimetre-scale electron transport. They are widespread in the sediment of seasonally hypoxic systems and their metabolic activity stimulates the dissolution of iron sulfides (FeS), releasing large quantities of ferrous iron (Fe2+) into the pore water. Upon contact with oxygen, Fe2+ oxidation forms a layer of iron(oxyhydr)oxides (FeOx), which in its turn can oxidize free sulfide (H2S) and trap phosphorus (P) diffusing upward. The metabolism of cable bacteria could thus prevent the release of H2S from the sediment and reduce the risk of euxinia, while at the same time modulating P release over seasonal timescales. However, experimental support for this so-called ‘iron firewall hypothesis’ is scarce. Here, we collected natural sediment in a seasonally hypoxic basin in three different seasons. Undisturbed sediment cores were incubated under anoxic conditions and the effluxes of H2S, dissolved iron (dFe) and phosphate (PO43−) were monitored for up to 140 days. Cores with recent cable bacterial activity revealed a high stock of sedimentary FeOx, which delayed the efflux of H2S for up to 102 days. Our results demonstrate that the iron firewall mechanism could exert an important control on the prevalence of euxinia and regulate the P release in coastal oceans.BT/Environmental Biotechnolog
Cable Bacteria Activity Modulates Arsenic Release From Sediments in a Seasonally Hypoxic Marine Basin
No full textEutrophication and global change are increasing the occurrence of seasonal hypoxia (bottom-water oxygen concentration <63 μM) in coastal systems worldwide. In extreme cases, the bottom water can become completely anoxic, allowing sulfide to escape from the sediments and leading to the development of bottom-water euxinia. In seasonally hypoxic coastal basins, electrogenic sulfur oxidation by long, filamentous cable bacteria has been shown to stimulate the formation of an iron oxide layer near the sediment-water interface, while the bottom waters are oxygenated. Upon the development of bottom-water anoxia, this iron oxide “firewall” prevents the sedimentary release of sulfide. Iron oxides also act as an adsorption trap for elements such as arsenic. Arsenic is a toxic trace metal, and its release from sediments can have a negative impact on marine ecosystems. Yet, it is currently unknown how electrogenic sulfur oxidation impacts arsenic cycling in seasonally hypoxic basins. In this study, we presented results from a seasonal field study of an uncontaminated marine lake, complemented with a long-term sediment core incubation experiment, which reveals that cable bacteria have a strong impact on the arsenic cycle in a seasonally hypoxic system. Electrogenic sulfur oxidation significantly modulates the arsenic fluxes over a seasonal time scale by enriching arsenic in the iron oxide layer near the sediment-water interface in the oxic period and pulse-releasing arsenic during the anoxic period. Fluxes as large as 20 μmol m −2 day −1 were measured, which are comparable to As fluxes reported from highly contaminated sediments. Since cable bacteria are recognized as active components of the microbial community in seasonally hypoxic systems worldwide, this seasonal amplification of arsenic fluxes is likely a widespread phenomenon.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

ANDRIC’S CRITICAL-ESSAYIST VIEWS ON ART
Full text linkAndrić je, između ostaloga, pisac koji oživotvoruje svaki fenomen čovjekova bivanja,
a posebno slikovito i djelotvorno u svojim kritičko-esejističkim radovima.
Ovaj referat obrađuje eseje o Goyi i Petrarci. U sabranim Andrićevim djelima
objavljenima posthumno (Istorija i legenda I. dio) pisac vješto opisuje tragiku Laurine
i Petrarcine nesuđene ljubavi, a filozofskoj estetici najzanimljivije i kasnije
Petrarcine refleksije o Laurinu liku za boravka u Avignonu. Tu autor niže osebujne
estetske predmetnosti iz prirode (krajolika) koju je i sam imao prilike vidjeti i
doživjeti. Referat ih pregledno navodi u citatima. U esejima o velikome španjolskom
slikaru romantizma Franciscu Goyi Andrić zapravo u obliku dijaloga zagovara
opravdanost i prirodu umjetničkoga djela. Suvremene, a i one ranije, teorije
filozofske estetike još nisu posve suglasne oko toga što je zapravo umjetničko djelo.
Postoje četiri velike estetičke teorije koje pokušavaju odgovoriti na to pitanje.
Andrić se okušao u opravdavanju karaktera umjetničkoga djela, i to vrlo smjelo
kroz lik i djelo jednoga od najvećih protagonista španjolske plastične umjetnosti
– Goyu, s jedne strane, te lik protagonista talijanske renesansne plodonosne književne
ere – Petrarcu, s druge strane. Njegov bi pristup danas estetičari nazvali
andrićevskim jer bi se mogao opisati kao svojevrstan spoj ovih navedenih teorija
koje su opravdane u razgovorima s Goyom.Andric is, among other things, a writer who brings to life every aspect of existence
of a man, what he particularly showed in his critical essay. This paper deals
with essays on Goya and Petrarca. In Andric’s collected works, published posthumously,
the first part, called History and Legend, skillfully describes the tragic
of the undestined love of Laura and Petrarch, while the most important part for
philosophical aesthetics would be Petrarch’s later reflections on the image of Laura
while her staying in Avignon. Here the author combines distinctive aesthetic
objects from nature (landscape), which he alone had a chance to see. They will
be presented in the paper through quotations. In essays about the great Spanish
romantic painter Francesco Goya, Andric actually argues, in form of a dialogue,
the validity and nature of a work of art. The definition of a work of art is yet to be
produced neither by the contemporary, nor by the earlier aesthetic theories. There
are four aesthetic theories which tried to answer this question. Andric tried to
argue for the character of a work of art very boldly through on one side, the person
and work of one of the greatest protagonists of Spanish plastic art – Goya, and
on the other side the figure of the protagonist of Italian renaissance – Petrarch.
His attitude would today be called an “Andrician” approach, because it combines
priorly mentioned theories, which were validated in conversations with Goya
Spirit of the land : politics, memory, and the sacred in South African land claims
No full textBibliography: leaves 224-242.This thesis examines the role of sacred space in people's attachment to land, analysing the ways in which people create sacred space through labour, ritual, myth, and memory. Three case studies explore the human interpretation of the sacred through the history and politics of land acquisition and dispossession. While providing historical background and legal analysis of forced removals, evictions, and relocations, the thesis calls attention to the role of religion in South African land claims. Although the people in these case studies believe that returning to their original land will materially improve their lives, their main concern is to reconnect with their alienated sacred space. This study explores the changing nature of the sacred and its formulative role in shaping and informing peopIe's identities and memories
Multi-target mode of action of Sulfodyne ® , a stabilized Sulforaphane, against pathogenic effects of SARS-CoV-2 infection
No full textAbstract The coronavirus disease 2019 (COVID-19) due to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has shown that, except vaccination, few therapeutics options for its treatment or prevention are available. Among the pathways that can be targeted for COVID-19 treatment, the Keap1/Nrf2 pathway seems of high interest as it regulates redox homeostasis and inflammation that are altered during SARS-CoV-2 infection. Here, we use three potent activators of the Keap1/Nrf2 pathway and showed that Sulfodyne ® , a stabilized natural Sulforaphane preparation with optimal bioavailability, had the highest antiviral activity in pulmonary or colonic epithelial cell lines even when added late after SARS-CoV-2 infection. This antiviral activity was not dependent on NRF2 activity but associated with action on ER stress and mTOR signaling that are activated during SARS-CoV-2 infection. Sulfodyne ® also decreased the inflammatory response of epithelial cell lines infected by SARS-CoV-2 independently of SARS-CoV-2 replication and reduced the activation of human monocytes that are recruited after infection of epithelial cells by SARS-CoV-2. Administration of Sulfodyne ® had little effects on SARS-CoV-2 replication in mice and hamsters infected with SARS-CoV-2 but significantly reduced weight loss and disease severity. Altogether, these results pinpoint the natural compound Sulfodyne ® as a potent therapeutic agent of COVID-19 symptomatology. Author Summary Accumulating evidence shows that oxidative stress coupled with the systemic inflammation contribute to COVID-19 pathogenesis. As the Keap1/Nrf2 pathway is the major regulator of redox homeostasis and promotes resolution of inflammation and as lung biopsies from COVID-19 patients showed a decreased NRF2 target gene signature, pharmacological agents that are known to activate NRF2 are good candidates for COVID-19 treatment. We show herein that Sulfodyne ® , an NRF2 activator that consists in a stabilized Sulforaphane preparation with optimal bioavailability, impairs SARS-CoV-2 replication in colonic or pulmonary epithelial cells. We show that this antiviral activity of Sulfodyne ® is not dependent of NRF2 activation, characterize the pathways associated with the Sulfodyne ® antiviral activity and show that Sulfodyne ® displays multiple actions that result in a decrease of the inflammation associated with SARS-CoV-2 infection. Finally, we show that Sulfodyne ® decreases the pathogenesis of mice or hamster infected with SARS-CoV-2. Overall, this study provides mechanistic explanations of the action of Sulfodyne ® during SARS-CoV-2 infection and suggests that Sulfodyne ® is a potential therapeutic agent of COVID-19 pathogenesis
