The spatial distribution pattern of soil organic carbon (SOC) directly influences carbon sequestration and climate regulation potential. However, in semi-arid alpine mountain regions, the spatial heterogeneity of SOC and its underlying driving mechanisms remain insufficiently investigated. Furthermore, empirical evidence for the quantitative assessment of soil carbon storage capacity across different vegetation units under natural conditions is still lacking.

T-cell acute lymphoblastic leukemia (T-ALL) is a malignant neoplastic disease. Accurate identification of core genes helps to explore the pathogenesis of T-ALL and develop relevant targeted drugs. In this paper, we first screened the RNA-seq, CTCF ChIP-seq and DNA methylation datasets of T-ALL for intersecting differentially expressed genes (DEGs) using bioinformatics software.
View Article and Find Full Text PDFFibroblast activation protein (FAP) is a highly expressed marker in cancer-associated fibroblasts (CAFs) across various epithelial cancers, making it an attractive target for diagnostic imaging. To address the limitations of existing FAP-targeted radiopharmaceuticals, such as poor tumor retention and off-target uptake, this study aimed to establish a comprehensive FAP nanobody library. Through systematic screening, we sought to identify a nanobody with cross-reactivity to both human and murine FAP, optimized for technetium-99m (Tc) labeling, and suitable for single-photon emission computed tomography (SPECT) imaging.

[Tc]Tc-HFaPSMA was prepared by Tc radiolabeling of a HYNIC-conjugated bispecific biomolecule HFaPSMA, which combines a PSMA-targeting motif (PhPSMA), a FAP-targeting ligand (GFAPI), a symmetric PEG-N-bis(PEG-acid) linker, and a chelator (HYNIC). Preclinical studies showed faster clearance and higher tumor uptake than that of its corresponding single-target radiotracers ([Tc]Tc-HPSMA and [Tc]Tc-HGFAPI).

Herein, we present a rationally engineered heterostructure comprising Pt single atoms (PtSAs) on nano metal-organic frameworks (MOF-74)/hollow double-shelled tubular CN (TCN), which addresses these limitations through synergistic effects. The Z-scheme heterojunction formed between MOF-74 and TCN establishes a built-in electric field, facilitating directional electron transfer from MOF-74 to PtSAs-modified TCN.

Immunohistochemistry (IHC) for PD-L1 detection is limited by its invasiveness and heterogeneity of tumors. To address these challenges, a new PD-L1-targeted nanobody-based immune-PET radiotracer [F]AlF-APN09 was developed using the site-specific radiolabeling method with the complexing agent (Mal-RESCA) under mild conditions. [F]AlF-APN09 was prepared at room temperature (pH 4.
