Methionine oxidation products as biomarkers of oxidative damage to proteins and modulators of cellular metabolism and toxicity

Redox Biochemistry and Chemistry
Proteins are highly abundant and readily oxidized targets of reactive species formed in biological systems, with these often accounting for greater than 50 % of the dry mass of biological samples.

Methionine sulfoxide reductase A is a stereospecific methionine oxidase

, 2011
Methionine sulfoxide reductase A (MsrA) catalyzes the reduction of methionine sulfoxide to methionine and is specific for the S epimer of methionine sulfoxide. The enzyme participates in defense against oxidative stresses by reducing methionine sulfoxide

Programmable 3D Photovoltaics via Mechanically Origami‐Coded Interlocked 3D Kirigami and Nano‐Root Anchored AgNWs–In–Ga Multiphasic Alloy Conductor

Advanced Materials, EarlyView.
Mechanically origami‐coded 3D kirigami photovoltaics convert a single extension–release cycle into deterministic self‐folding, reconfiguring planar solar cells into programmable 3D modules. Distinct coding strategies enable either ultrahigh stretchability (500% system strain) or ultrahigh initial effective areal coverage (225%).

Post-thaw dimethyl sulfoxide reduction in autologous peripheral blood progenitor cell suspensions

Hematology, Transfusion and Cell Therapy
Background and objectives: Dimethyl sulfoxide has become the most common cryoprotectant used for cryopreservation of hematopoietic progenitor cells because of its efficiency, regardless of its potentially toxic side effects. Its application is considered

Ultra‐High‐Throughput Discovery of Multifunctional Polyphenolic Coatings on Droplet Microarrays

Advanced Materials, EarlyView.
An ultra‐high‐throughput (UHT) combinatorial strategy enables the miniaturized synthesis and screening of ≈30 000 polyamine‐polyphenolic (PaPp) coatings using droplet microarrays (DMA). This approach reveals hundreds of previously unknown fluorescent, redox‐active, and antibacterial materials, including multifunctional, cell‐compatible surfaces ...

Aromatic sulfide, sulfoxide, and sulfone mediated mesoporous carbon monolith for use in supercapacitor

, 2012
Monoliths of aromatic sulfur mediated mesoporous carbon were fabricated via an aqueous self-assembly strategy and the species of sulfide, sulfoxide, and sulfone on the surface can be tuned rationally.

Efficient Osmotic Energy Conversion Enabled by Self‐Standing COF Membranes With Varied Sulfonic Acid Group Density

Advanced Materials, EarlyView.
Self‐standing, strong sulfonated covalent organic framework membranes with varied ionic‐group density are developed for osmotic energy conversion. Optimized charge‐governed nanochannels enable highly selective ion transport, delivering a power density of 24.53 W m−2 under seawater/freshwater salinity gradients.

Stereochemical Aspects of Sulfoxides and Metal Sulfoxide Complexes

Croatica Chemica Acta, 1999
Structural parameters of free and metal coordinated sulfoxides are reviewed and updated average values are derived. For uncoordinated sulfoxides, the average S−O bond distance is 1.4918(9) Å. This value is lengthened to 1.528(1) Å upon O-coordination to metal ions, while it is reduced to 1.4731(6) Å upon S-coordination.

Dimethyl sulfoxide complexes of silver(I) in solution

, 1971
The stability constants of dimethyl sulforxide complexes of silver (I) in methanol, 2-butanol, acetone, sulfolane, 70% dioxane, and nitroethane were determined by potentiometric titrations. No dimethyl sulfoxide complexes of silver(I) are formed in water.
