Observation of Robust Compressed CuO Octahedra and Exotic Spin Structure in CaCuFeO.

CuO octahedra usually show elongated distortion, leading to active orbitals and planar exchange interactions, while compressed CuO octahedra with active orbitals and unidirectional exchange interactions are exceptionally rare. Here, we design and synthesize a new frustrated antiferromagnet CaCuFeO through a high-pressure and high-temperature approach, in which robust compressed CuO octahedra are realized, separating the FeO sheets that comprise zigzag spin ladders. Magnetic susceptibility and specific heat measurements exhibit a long-range antiferromagnetic order below the Néel temperature of 165 K, which is further confirmed by neutron diffraction.

Novel inflammatory markers in intracerebral hemorrhage: Results from Olink proteomics analysis.

Inflammation is a crucial factor in intracerebral hemorrhage (ICH) pathophysiology, but specific inflammatory biomarkers in ICH patients remain unclear. This study aimed to identify novel circulating inflammatory biomarkers for improved ICH prediction and diagnosis. We profiled expression levels of 92 cardiovascular disease related proteins in plasma from 26 matched ICH patients and controls using Olink technology.

Exploring Logical Intuition in Base-Rate Problems Using the Instructional Manipulation Paradigm.

The default-interventionist model of dual-process theories proposes that stereotype descriptions in base-rate problems are processed using Type 1 processing, while the evaluation of base rates depends on Type 2 processing. The logical intuition view posits that people can process base-rate information using Type 1 processing. This study examined the logical intuition view using the instructional manipulation paradigm.

A Fast, High-Sensitivity 96-Well Plate-Based MICROFASP Method for Processing Low Microgram Proteomics Sample within 1.5 h.

A rapid, sensitive, and high-throughput sample preparation method is of paramount significance for proteomics analysis. Here, we report a fast, high-sensitivity MICROFASP method that is capable of completing sample preparation within 1.5 h, enhancing the throughput by over 13 times compared to the previous reports.

Pim3 up-regulation by YY1 contributes to diabetes-induced cardiac hypertrophy and heart failure.

Objectives: The close relationship of proto-oncogenes to myocardial hypertrophy has long been recognized, and cardiac hypertrophy leads to heart failure (HF). However, whether proviral insertion of Moloney virus 3 kinase (Pim3), a proto-oncogene, contributes to cardiac hypertrophy in diabetes mellitus (DM) remains unknown. This study aims to investigate whether Pim3 is involved in DM-induced cardiac hypertrophy and HF and to elucidate its underlying mechanisms.
