A whole-body imaging technique for tumor-specific diagnostics and screening of B7-H3-targeted therapies.
J Clin Invest
January 2025
Department of Nuclear Medicine, Peking University Cancer Hospital & Institute, Beijing, China.
Background: B7-H3 or CD276 is notably overexpressed in various malignant tumor cells in humans, with extremely high expression rates. The development of a radiotracer that targets B7-H3 may provide a universal tumor-specific imaging agent and allow the noninvasive assessment of the whole-body distribution of B7-H3-expressing lesions.
Methods: We enhanced and optimized the structure of an affibody (ABY) that targets B7-H3 to create the radiolabeled radiotracer [68Ga]Ga-B7H3-BCH, and then, we conducted both foundational experiments and clinical translational studies.
Recent advances in the management of pediatric cholestatic liver diseases.

Department of Pediatrics, Children's Hospital of Colorado, University of Colorado, Aurora, Colorado, USA.
Pediatric cholestatic liver diseases are rare conditions that can result from multiple specific underlying etiologies. Among the most common etiologies of pediatric cholestatic liver diseases are biliary atresia, Alagille syndrome (ALGS), and inherited disorders of bile acid transport. These diseases are characterized by episodic or chronic unremitting cholestasis.

Typhoid fever is a multisystemic illness caused by and , transmitted fecal orally through contaminated water and food. It is a rare diagnosis in the US, with most cases reported in returning travelers. Hepatitis and cholestasis are rare sequelae of infection.

BMC Med
January 2025
Research Institute for Biomedical Sciences, Tokyo University of Science, Chiba, Japan.
Background: A new circulating biomarker superior to carbohydrate antigen 19-9 (CA19-9) is needed for diagnosing pancreatobiliary cancer (PBca). The aim of this study was to identify serum microRNA (miRNA) signatures comprising reproducible and disease-related miRNAs.
Methods: This multicenter study involved patients with treatment-naïve PBca and healthy participants.
Genomic and transcriptomic signatures of sequential carcinogenesis from papillary neoplasm to biliary tract cancer.
J Hepatol
January 2025
Department of Pathology, Yonsei University College of Medicine, Seoul, Republic of Korea; Severance Biomedical Science Institute, Yonsei University College of Medicine, Seoul, Republic of Korea. Electronic address:
Background & Aims: Papillary neoplasms of the biliary tree, including intraductal papillary neoplasms (IPN) and intracholecystic papillary neoplasms (ICPN), are recognized as precancerous lesions. However, the genetic characteristics underlying sequential carcinogenesis remain unclear.
Methods: Whole-exome sequencing was performed on 166 neoplasms (33 intrahepatic IPNs, 44 extrahepatic IPNs, and 89 ICPNs), and 41 associated carcinomas.
