Ultrafine metal-organic framework @ graphitic carbon with MoS-CNTs nanocomposites as carbon-based electrochemical sensor for ultrasensitive detection of catechin in beverages.

GO/Co-MOF/PPy-350 (GPC-350) was synthesized by in situ growth of ultrafine Co-MOF on graphene oxide (GO), followed by encapsulation with polypyrrole (PPy) and calcination at 350.0℃. Meanwhile, MoS-MWCNTs (MoS-CNTs) were produced via the in situ synthesis of MoS within multi-walled carbon nanotubes (MWCNTs).

Efficacy and safety of low-dose TBI combined MAC regimen for HSCT in high-risk AML patients with active disease.

Background: The management of high-risk acute myeloid leukaemia (AML) remains challenging, highlighting the need for innovative conditioning strategies beyond current regimens.

Methods: In the present single-arm study, a FACT regimen comprised of low-dose total body irradiation (TBI) with fludarabine, cytarabine and cyclophosphamide was employed to treat cytogenetically high-risk AML patients exhibiting pre-transplant active disease. This clinical trial is registered in the Chinese Clinical Trial Registry with the registration number ChiCTR2000035111.

Photocatalytic Oxidative Coupling of Methane to Ethane Using CO2 as a Soft Oxidant Over the Au/TiO2-Vo Nanosheets.

Herein, we first report a photocatalytic OCM using CO2 as a soft oxidant for C2H6 production under mild conditions, where an efficient photocatalyst with unique interface sites is constructed to facilitate CO2 adsorption and activation, while concurrently boosting CH4 dissociation. As a prototype, the Au quantum dots anchored on oxygen-deficient TiO2 nanosheets are fabricated, where the Au-Vo-Ti interface sites for CO2 adsorption and activation are collectively disclosed by in situ Kelvin probe force microscopy, quasi in situ X-ray photoelectron spectroscopy and theoretical calculations. Compared with single metal site, the Au-Vo-Ti interface sites exhibit the lower CO2 adsorption energy and decrease the energy barrier of the *CO2 hydrogenation step from 1.

Comparative transcriptome analysis and heterologous overexpression indicate that the ZjZOG gene may positively regulate the size of jujube fruit.

Background: Fruit size is a crucial economic trait that impacts the quality of jujube (Ziziphus jujuba), however, research in this area remains limited. This study utilized two jujube cultivars with similar genetic backgrounds but differing fruit sizes to investigate the regulatory mechanisms affecting fruit size through cytological observations, transcriptome sequencing, and heterologous overexpression.

Results: The findings reveal that variations in mesocarp cell numbers during early fruit development significantly influence final fruit size.

[Gly14]-Humanin ameliorates high glucose-induced endothelial senescence via SIRT6.

High glucose (HG) induced endothelial senescence is related to endothelial dysfunction and cardiovascular complications in diabetic patients. Humanin, a member of mitochondrial derived peptides (MDPs), is thought to contribute to aging-related cardiovascular protection. The goal of the study is to explore the pathogenesis of HG-induced endothelial senescence and potential anti-senescent effects of Humanin.
