Sintering Evolving MnO-LaMnO Perovskite Heterointerfaces as Highly Active and Durable Catalysts for Catalytic Removal of Volatile Organic Compounds.

Improving the catalyst performance for the thermal oxidation reaction faces the daunting challenge of the activity-stability trade-off. Herein, an evolved heterointerface was constructed on spherical MnO nanocatalysts to achieve exceptional stability while maintaining adequate activity by simply introducing La. The generation of the active MnO-MnO heterointerfaces by La doping was experimentally observed, which further segregates to the surface during thermal aging and forms epitaxially grown heterostructured LaMnO-MnO with Mn atoms.

Extraordinary synergy on 3D hierarchical porous Co-Cu nanocomposite for catalytic elimination of VOCs at low temperature and high space velocity.

It is still a challenge to develop hierarchically nanostructured catalysts with simple approaches to enhance the low-temperature catalytic activity. Herein, a set of mesoporous Co-Cu binary metal oxides with different morphologies were successfully prepared via a facile ammonium bicarbonate precipitation method without any templates or surfactants, which were further applied for catalytic removal of carcinogenic toluene. Among the catalysts with different ratios, the CoCu composite oxide presented the best performance, where the temperature required for 90% conversion of toluene was only 237°C at the high weight hour space velocity (WHSV) of 240,000 mL/(g·hr).

In Situ Reconstruction of Active Heterointerface for Hydrocarbon Combustion through Thermal Aging over Strontium-Modified CoO Nanocatalyst with Good Sintering Resistance.

The issue of catalyst deactivation due to sintering has gained significant attention alongside the rapid advancement of thermal catalysts. In this work, a simple Sr modification strategy was applied to achieve highly active CoO-based nanocatalyst for catalytic combustion of hydrocarbons with excellent antisintering feature. With the CoSr catalyst achieving a 90% propane conversion temperature () of only 289 °C at a w8 hly space velocity of 60,000 mL·g·h, 24 °C lower than that of pure CoO.

Prognostic significance of persisting DNMT3A, ASXL1, and TET2 mutation burden in acute myeloid leukemia patients with allogeneic hematopoietic stem cell transplantation during complete remission.

We retrospectively analyzed 155 AML patients with DAT mutations at diagnosis who underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) at complete remission. Of the 155 AML patients with DAT mutations at diagnosis, 59 (38.1%) patients had persisting DAT mutations pretransplantation.

RUNX1 together with DAT mutations predicted poor outcome in acute myeloid leukemia.

We retrospectively explored the prognostic impact of DAT mutations at diagnosis in 122 RUNX1 AML patients. RUNX1 missense mutation was dominant in the RUNT domain, and frameshift mutation was dominant in the TAD domain. DAT mutations occurred in 38.

Recurrent Novel Translocations in B-Lymphoblastic Leukemia/Lymphoma.

Translocations involving the immunoglobulin heavy chain () locus are common abnormalities in B-lymphoblastic leukemia/lymphoma (B-ALL) and multiple myeloma. These rearrangements result in a juxtaposition of enhancers to the vicinity of oncogenes, such as and , leading to the upregulation of oncogenes. Here, we identified recurrent novel translocations in three B-ALL patients by transcriptome sequencing.

The Clinical Characteristics and Prognosis of AYA and Older Adult ETP-ALL/LBL: A Real-World Multicenter Study in China.

Early T-cell precursor (ETP) lymphoblastic leukemia/lymphoma is a high-risk T lymphoblastic leukemia/lymphoma (T-ALL/LBL) subgroup. We performed a real-world multicenter study to explore the clinical characteristics and prognosis of adolescent and young adults (AYA) and older adult ETP leukemia/lymphoma. A total of 103 patients with ETP-ALL/LBL in five centers in China between January 2016 and February 2021 were included in this study.

Research Progress on the Role of Intermediate Filament Vimentin in Atherosclerosis.

The cytoskeleton is a biopolymer network composed of intermediate filaments, actin, and microtubules, which is the main mechanical structure of cells. Vimentin is an intermediate filament protein that regulates the mechanical and contractile properties of cells, thereby reflecting their mechanical properties. In recent years, the "nonmechanical function" of vimentin inside and outside of cells has attracted extensive attention.

Krebs Cycle Rewired: Driver of Atherosclerosis Progression?

The tricarboxylic acid (TCA) cycle is the center of energy metabolism in eukaryotic cells and is dynamically adjusted according to the energy needs of cells. Macrophages are activated by inflammatory stimuli, and then two breakpoints in TCA cycle lead to the accumulation of intermediates. Atherosclerosis is a chronic inflammatory process.

PD-1/PD-L1 immune checkpoints: Tumor vs atherosclerotic progression.

Immunotherapy has become one of the most attraction cancer therapy strategies. The PD-1/PD-L1 pathway plays key roles in immune responses and autoimmunity by regulating T cell activity. Overactivation of this pathway dampens T cell and immune function, which allows tumor cells immune escape.

OxLDL induces vascular endothelial cell pyroptosis through miR-125a-5p/TET2 pathway.

Pyroptosis participates in the formation and development of atherosclerosis (As) by promoting inflammatory factor release and is closely related to the stability of atherosclerotic plaque. MicroRNAs can regulate the expression of target genes at the posttranscriptional level. Previous studies have shown that miR-125a-5p increases in hyperlipidemic-hyperglycemic conditions and is involved in apoptosis, but its specific role in pyroptosis and As remains unclear.
