Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

open access: yesAdvanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Thiol-thiol cross-clicking using bromo-ynone reagents

open access: yesNature Communications
Thiols are used in many click reactions, and are also excellent platforms for biomolecular click or bioconjugation reactions. The direct cross-coupling of two thiols is an attractive biomimetic concept for click chemistry, but leads to statistical ...

Ebselen Not Only Inhibits Clostridioides difficile Toxins but Displays Redox-Associated Cellular Killing

open access: yesMicrobiology Spectrum, 2021
Ebselen, a reactive organoselenium compound, was shown to inhibit toxins TcdA and TcdB by covalently binding to their cysteine protease domains. It was suggested that ebselen lacked antimicrobial activity against Clostridioides difficile.

Redox and Thiols in Archaea

open access: yes, 2020
Low molecular weight (LMW) thiols have many functions in bacteria and eukarya, ranging from redox homeostasis to acting as cofactors in numerous reactions, including detoxification of xenobiotic compounds.

Reaction of peroxynitrite with thiols, hydrogen sulfide and persulfides

open access: yesRedox Biochemistry and Chemistry
Three decades of research on the biochemistry of peroxynitrite (ONOOH/ONOO−) have established that this stealthy oxidant is formed in biological systems, and that its main targets are carbon dioxide (CO2), metalloproteins and thiols (RSH).

The nitrite anion: the key intermediate in alkyl nitrates degradative mechanism. [PDF]

open access: yes, 2007
Alkyl nitrates, _in vivo_, are metabolized to yield nitric oxide, and thiol groups are considered necessary cofactors. This statement is based on studies that underline how these species potentiate hemodynamic responsiveness to nitrates in patients with ...

Electrostatic Superlattices Beyond 1:1 Stoichiometry

open access: yesAdvanced Functional Materials, EarlyView.
Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl

Total Thiols and MDA Levels in Patients with Acute Myocardial Infarction Before and After Reperfusion Therapy [PDF]

open access: yes, 2010
Background: Reactive oxygen species have been implicated in the pathogenesis of ischemic and reperfusion injury. In the current work we have measured malondialdehyde (MDA), total thiols, total CK, CK-MB and AST in ECG proven acute myocardial infarction ...
