The Latest Progress in the Chemistry of Alkaloids.

alkaloids (DAs) are interesting molecules with rich molecular skeletons and diverse biological activities. Since their discovery, phytochemists have isolated, purified, and identified more than 350 DAs. Synthetic chemists, attracted by the structure and activity of DAs, have accomplished many elegant synthetic jobs.

Unusual pulmonary nodules diffusion from epithelial‑myoepithelial carcinoma on F‑FDG PET/CT: A case report.

Epithelial-myoepithelial carcinoma (EMC) is a rare low-grade malignant tumor with uncommon regional lymph node metastasis and distant metastasis. The diagnosis of this disease primarily relies on the examination of pathological morphology and immunohistochemical staining, as its clinical symptoms and imaging findings are non-specific. This makes it more difficult to provide specific information about EMC lung metastasis.

Fluorescence and magnetic resonance imaging of ONL-93 cells in a rat model of ischemic.

Objectives: The current methods for detecting myelin changes in ischemic stroke are indirect and cannot accurately reflect their status. This study aimed to develop a novel fluorescent-magnetic resonance dual-modal molecular imaging probe for direct imaging of myelin.

Methods: Compounds 7a and 7b were synthesized by linking the MeDAS group and Gadolinium (III) 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetate.

Aberrant expression of p-STAT3 in peripheral blood CD4+ and CD8+ T cells related to hepatocellular carcinoma development.

Hepatocellular carcinoma (HCC) is one of the most common cancer types worldwide. The signal transducer and activator of transcription 3 (STAT3) protein is a member of the STAT transcription factor family. Oncogenesis, invasion, and metastasis of HCC are associated with activation of STAT3.
