An iron-base oxygen-evolution electrode for high-temperature electrolyzers.

High-temperature molten-salt electrolyzers play a central role in metals, materials and chemicals production for their merit of favorable kinetics. However, a low-cost, long-lasting, and efficient high-temperature oxygen evolution reaction (HT-OER) electrode remains a big challenge. Here we report an iron-base electrode with an in situ formed lithium ferrite scale that provides enhanced stability and catalytic activity in both high-temperature molten carbonate and chloride salts.

CircFKBP5 Suppresses Apoptosis and Inflammation and Promotes Osteogenic Differentiation.

Objectives: Dental pulp stem cells (DPSCs) are a type of mesenchymal stem cell possessing self-renewal and multilineage differentiation capabilities. The dysfunction of DPSCs is related to the pathologic process of pulpitis. The participation of circular RNAs (circRNAs) in DPSC differentiation has been identified.

Inhibition of herpes simplex virus by myricetin through targeting viral gD protein and cellular EGFR/PI3K/Akt pathway.

Myricetin, a common dietary flavonoid, was reported to possess many different biological activities such as anti-oxidant, anti-inflammatory, and antiviral effects. In this study, we explored the anti-HSV effects and mechanisms of myricetin both in vitro and in vivo. The results showed that myricetin possessed anti-HSV-1 and HSV-2 activities with very low toxicity, superior to the effects of acyclovir.

Guanidine modifications enhance the anti-herpes simplex virus activity of (E,E)-4,6-bis(styryl)-pyrimidine derivatives in vitro and in vivo.

Background And Purpose: The worldwide prevalence of herpes simplex virus (HSV) and shortage of efficient therapeutic strategies to counteract it are global concerns. In terms of treatment, the widely utilized anti-HSV drugs such as acyclovir have serious limitations, for example, drug resistance and side effects. Here, we have identified the guanidine-modified (E,E)-4,6-bis(styryl)-pyrimidine (BS-pyrimidine) derivative compound 5d as an inhibitor of HSV and further elucidated the anti-HSV mechanisms of compound 5d both in vitro and in vivo.

A sulfated glucuronorhamnan from the green seaweed Monostroma nitidum: Characteristics of its structure and antiviral activity.

A water-soluble polysaccharide from Monostroma nitidum, designated MWS, was isolated using water extraction, anion-exchange and size-exclusion chromatography. MWS was a sulfated glucuronorhamnan consisting of →3)-α-l-Rhap-(1→, →4)-β-d-GlcpA-(1→ and →2)-α-l-Rhap-(1→ units. Sulfate ester groups located at C-4/C-2 of →3)-α-l-Rhap-(1→ and C-4/C-3 of →2)-α-l-Rhap-(1→ units.
