Acute myeloid leukemia (AML) featuring retinoic acid receptor-gamma (RARG) rearrangements exhibits morphological features resembling those of acute promyelocytic leukemia but is associated with drug resistance and poor clinical outcomes. However, the mechanisms underlying the role of RARG fusions in leukemogenesis remain elusive. Here, we show that RARG fusions disrupt myeloid differentiation and promote proliferation and self-renewal of hematopoietic stem and progenitor cells (HSPCs) by upregulating BCL2 and ATF3.

This study aims to investigate the physiological changes in growth and metabolic response mechanisms of highland barley under different concentrations of cadmium. To achieve this, cadmium stress was applied to green barley at levels of 20, 40, and 80 mg/L. The results revealed that, under Cd(II) stress, the chlorophyll content and photosynthesis in leaves of highland barley seedlings were inhibited to some extent.

Planar chirality found tremendous use in many fields, such as chemistry, optics, and materials science. In particular, planar chiral [2.2]paracyclophanes (PCPs) are a type of structurally interesting and practically useful chiral compounds bearing unique electronic and photophysical properties and thus have been widely used in π-stacking polymers, organic luminescent materials, and as a valuable toolbox for developing chiral ligands or organocatalysts.

A series of N-Het·BH and AAE·BH complexes were prepared in moderate to high yields and the single-crystal structures of products 3, 31, 34, and 59 were determined. The N-Het·BH and AAE·BH complexes possess high stability, endowing these products with potential applications in luminescent and boron-containing drugs. The optical properties of the representative products have been preliminarily studied.

Background And Purpose: This study aims to investigate the longitudinal changes in translocator protein (TSPO) following stroke in different brain regions and potential associations with chronic brain infarction.
Methods: Twelve patients underwent SPECT using the TSPO tracer 6-Chloro-2-(4'-123I-Iodophenyl)-3-(N,N-Diethyl)-Imidazo[1,2-a]Pyridine-3-Acetamide, as well as structural MRI, at 10, 41, and 128 days (median) after ischemic infarction in the middle cerebral artery. TSPO expression was measured in lesional (MRI lesion and SPECT lesion), connected (pons and ipsilesional thalamus), and nonconnected (ipsilesional cerebellum and contralesional occipital cortex) regions.
