Sequential detection of hypochlorous acid and sulfur dioxide derivatives by a red-emitting fluorescent probe and bioimaging applications and .

Hypochlorous acid (HOCl) and sulfur dioxide derivatives (SO /HSO ) play critical roles in complex signal transduction and oxidation pathways. Therefore, it is meaningful and valuable to detect both HOCl and SO derivatives in biosystems by a fluorescence imaging assay. In this work, we developed a red-emitting fluorescent probe (DP) by the condensation of malononitrile and phenothiazine derivatives through a C[double bond, length as m-dash]C double bond.

Simultaneously formed and embedding-type ternary MoSe/MoO/nitrogen-doped carbon for fast and stable Na-ion storage.

To obtain an electrode material that is capable of manifesting high Na-ion storage capacity during long-term cycling at a rapid discharge/charge rate, ternary heterophases MoSe/MoO/carbon are rationally designed and synthesized through a supermolecule-assisted strategy. Through using supermolecules that are constructed from MoO and polydopamine as the precursor and sulfonated polystyrene microspheres as the sacrificial template, the formed ternary phases MoSe/MoO/carbon are fabricated into a hollow microspherical structure, which is assembled from ultrathin nanosheets with MoSe and MoO nanocrystallites strongly embedded in a nitrogen-doped carbon matrix. In the ternary phases, the MoSe phase contributes to a high Na-ion storage capacity by virtue of its layered crystalline structure with a wide interlayer space, while the surrounding MoO and porous nitrogen-doped carbon phases are conducive to rate behaviour and cycling stability of the ternary hybrids since both the two phases are beneficial for electronic transport and structural stability of MoSe during repeated sodiation/desodiation reaction.

MicroRNA-150 regulates glycolysis by targeting von Hippel-Lindau in glioma cells.

Warburg effect, characterized by enhanced glycolysis and lactate production, even under aerobic conditions, is one of the hallmarks of cancer cells. However, the mechanism underlying this phenomenon remains poorly understood. Previous studies have shown that microRNA-150 (miR-150) is significantly up-regulated in various malignancies and represents a putative onco-miRNA in human cancers.
