The present study aimed to investigate the association of ARID5B rs10821936, IKZF1 rs4132601, PIP4K2A rs7088318, and GATA3 rs3824662 gene polymorphisms with the susceptibility and prognosis of childhood ALL in China. We found that the C allele of rs10821936 (ARID5B) and the A allele of rs3824662 (GATA3) were associated with an increased risk of childhood ALL in the Chinese population.

Angew Chem Int Ed Engl
December 2021
Defects have been found to enhance the electrocatalytic performance of NiFe-LDH for oxygen evolution reaction (OER). Nevertheless, their specific configuration and the role played in regulating the surface reconstruction of electrocatalysts remain ambiguous. Herein, cationic vacancy defects are generated via aprotic-solvent-solvation-induced leaking of metal cations from NiFe-LDH nanosheets.

- Understanding the oxygen reduction reaction (ORR) is crucial for designing effective fuel-cell catalysts, and surface enhanced Raman spectroscopy (SERS) is a technique that can detect vibrational bonds at the molecular level but is challenging for practical nanocatalysts.
- Shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS) was successfully used to analyze the ORR on bimetallic Pt-Co nanocatalysts, providing direct evidence of an associative mechanism in both acidic and basic environments.
- Density functional theory (DFT) calculations reveal that the improved ORR activity on Pt-Co surfaces is due to weak oxygen adsorption influenced by electronic effects, highlighting SHINERS as a valuable method for
The single molecular conductance of amino acids was measured by a scanning tunneling microscope (STM) break junction. Conductance measurement of alanine gives out two conductance values at 10 G₀ (1095 nS) and 10 G₀ (15.5 nS), while similar conductance values are also observed for aspartic acid and glutamic acid, which have one more carboxylic acid group compared with alanine.
