Gold nanorod in silver tetrahedron: Cysteamine mediated synthesis of SERS probes with embedded internal markers for AFP detection.
Anal Chim Acta
February 2025
The Key Laboratory of Biomedical Information Engineering of Ministry of Education, School of Life Science and Technology, Xi'an Jiaotong University, No. 28 Xianning West Road, Xi'an, 710049, China. Electronic address:
Background: Plasmonic core-shell nanostructures with embedded internal markers used as Raman probes have attracted great attention in surface-enhanced Raman scattering (SERS) immunoassay for cancer biomarkers due to their excellent uniform enhancement. However, current core-shell nanostructures typically exhibit a spherical shape and are coated with a gold shell, resulting in constrained local field enhancement.
Results: In this work, we prepared a core-shell AuNR@BDT@Ag structure by depositing silver on the surface of Raman reporter-modified gold nanorods (AuNR).
Psoas Muscle Index as an Independent Predictor of Survival in Patients with Hepatocellular Carcinoma Receiving Systemic Targeted Therapy.
Cancers (Basel)
January 2025
Department of Gastroenterology and internal Medicine, Graduate School of Medicine, Gifu University, 1-1 Yanagido, Gifu 501-1194, Japan.
Background: This study aimed to investigate the usefulness of the psoas muscle index (PMI) as an independent predictor of survival after systemic targeted therapy initiation in patients with hepatocellular carcinoma (HCC).
Method: In total, 214 patients with HCC who underwent systemic targeted therapy at the Gifu University Hospital were enrolled. The correlation between the PMI and the skeletal muscle index (SMI) was assessed using Pearson's correlation coefficient (PCC).
Carcinoma of Unknown Primary: Integrating Timely Interventions and Molecular Advancements for Improved Outcomes.
Cureus
December 2024
Hematology and Medical Oncology, University of Kentucky College of Medicine, Lexington, USA.
Carcinoma of unknown primary (CUP) is a diverse group of malignancies characterized by metastatic disease without an identified primary site. It typically presents with a poor prognosis due to widespread metastasis at diagnosis. This report discusses a 58-year-old female patient with advanced CUP and diffuse liver metastasis.

December 2024
Department of Hepatology, Gastroenterology, and Infectious Diseases, Al-Azhar University, Assiut, EGY.
Background There is ongoing debate regarding the impact of direct-acting antiviral drugs (DAAs) on the occurrence of de novo hepatocellular carcinoma (HCC). Vascular endothelial growth factor (VEGF) plays a crucial role in the development and angiogenesis of HCC. Aim This study aims to evaluate dynamic changes in vascular endothelial growth factor (VEGF) levels at different point times during and after treatment of HCV to evaluate the risk of de novo HCC in DAAs-treated HCV patients.
