Photocatalytic oxidative coupling of methane with oxygen is promising to obtain valuable muti-carbon products, yet suffering low reactivity. Here, we apply cerium modifications on zinc oxide-supported gold catalysts based on the electronic asymmetry design of lattice oxygen to improve the coupling activity. The methane conversion rate exceeds 16000 μmol g h with muti-carbon selectivity of 94.

In recent years, the connection between APOBEC3 cytosine deaminases and cancer mutagenesis has become ever more apparent. This growing awareness and lack of inhibitory drugs has created a distinct need for biochemical tools that can be used to identify and characterize potential inhibitors of this family of enzymes. In response to this challenge, we have developed a Real-time APOBEC3-mediated DNA Deamination (RADD) assay.

Article Synopsis
  • Challenges with NaV(PO) related to electronic conductivity and cycling stability have driven research to enhance its performance using a sol-gel method that incorporates F/Al doping and carbon nanotube (CNT) wrapping.
  • * The combination of F and Al doping improves structural stability and Na migration channels, leading to better overall electrochemical performance, with modified FAl-2 achieving a high capacity retention rate of 93.84% after 2000 cycles.
  • * FAl-2 also displays low volume shrinkage during charging and discharging, superior thermal stability, and insights into battery management design, making it a promising option for use in batteries.

Article Synopsis
  • DNA deaminase toxins, like the single-stranded DNA deaminase SsdA, play roles in bacterial competition and genetic diversity while also serving as tools for genome engineering.
  • The crystal structure of SsdA bound to single-stranded DNA shows a unique binding mode that allows for broad substrate selectivity, characterized by a V-shaped conformation around the target cytosine.
  • Key findings include the identification of a β-amino acid isoaspartate in SsdA that's crucial for its activity and stability, paving the way for engineered mutants that could be used in human cells for future genome editing applications.

Chemical recycling is a promising strategy to establish a circular plastic economy, and it is still in an early stage of development. In this work, the reductive depolymerization of polyesters and polycarbonates into their corresponding borylated alcohols promoted by heterogeneous lanthanum materials was described. Grafting the easily accessible lanthanum tris(aminobenzyl) complex La(CHCHNMe-) () onto the partially dehydroxylated silica support SBA-15 (SBA-15 or SBA-15) gave the inorganic-organic hybrid materials @SBA-15 and @SBA-15.

Hispanic children with acute lymphoblastic leukemia (ALL) have lower 6-mercaptopurine (6MP) adherence and greater hazard of relapse compared with non-Hispanic White children. We examined the association between Spanish language and 6MP adherence, and hazard of relapse. 6MP adherence was measured electronically over a 6-month period.

The association between antimetabolite dose intensity (DI) and adverse events among children receiving maintenance therapy for acute lymphoblastic leukemia (ALL) remains unclear, especially in the context of antimetabolite adherence. Using Children's Oncology Group AALL03N1 data, we examined the association between high DI during the first 4 study months and (i) treatment-related toxicities during the subsequent 2 study months; and (ii) relapse risk. Patients were classified into a high DI phenotype (either 6-mercaptopurine [6-MP] or methotrexate [MTX] DI ≥110% during the first 4 study months, or 6-MPDI or MTXDI 100%-110% at study enrollment and ≥25% increase over the 4 study months) and normal DI phenotype (all others).

Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2, SARS2) is responsible for the COVID-19 pandemic and infections that continue to affect the lives of millions of people worldwide, especially those who are older and/or immunocompromised. The SARS2 main protease enzyme, M (also called 3C-like protease, 3CL), is a bona fide drug target as evidenced by potent inhibition with nirmatrelvir and ensitrelvir, the active components of the drugs Paxlovid and Xocova, respectively. However, the existence of nirmatrelvir and ensitrelvir-resistant isolates underscores the need to develop next-generation drugs with different resistance profiles and/or distinct mechanisms of action.

Purpose: Therapy-related myeloid neoplasm (t-MN) is a life-threatening complication of autologous peripheral blood stem cell (PBSC) transplantation for non-Hodgkin lymphoma (NHL). Previous studies report an association between clonal hematopoiesis (CH) in PBSC and risk of t-MN, but small samples precluded examination of risk within specific subpopulations.

Methods: Targeted DNA sequencing was performed to identify CH mutations in PBSC from a retrospective cohort of 984 patients with NHL (median age at transplant, 57 years; range, 18-78).
