Undifferentiated embryonal sarcoma of the liver with epithelioid features in an adult patient: A case report.

Introduction: Undifferentiated embryonal sarcoma of the liver (UESL) is a rare form of liver malignancy, with most cases reported in the pediatric population. This disease is extremely uncommon in adults. Herein, we report the first case of UESL with epithelioid features in an adult patient.

Clinical validation of the risk scoring systems of postoperative pancreatic fistula after laparoscopic pancreatoduodenectomy in Chinese cohorts: A single-center retrospective study.

Background: Although several prediction models for the occurrence of clinically relevant postoperative pancreatic fistula after laparoscopic pancreatoduodenectomy exist, most were established using Western cohorts. The utility of these models using a Chinese cohort has not been validated widely. The aim of this study was to validate the original Fistula Risk Score, the alternative Fistula Risk Score, and the updated alternative Fistula Risk Score for patients undergoing laparoscopic pancreatoduodenectomy in a large-scale Chinese cohort externally.

Neuroendocrine tumors of the gallbladder.

A gallbladder neuroendocrine neoplasm (GB-NEN) is a unique heterogeneous neoplasm, originating from neuroendocrine cells and able to secrete peptides as its neurotransmitter. Among all the neuroendocrine tumors (NETs), the GB-NEN prevalence is 0.5%, which accounts for ~2.

A Zn-Based Metal-Organic Framework with a Rare tcj Topology as a Turn-On Fluorescent Sensor for Acetylacetone.

A Zn-based metal-organic framework (MOF) with a rare tcj topology has been solvothermally synthesized and displays relatively good thermal and chemical stabilities. Interestingly, the MOF can sensitively and selectively sense acetylacetone (acac) via a fluorescence enhancement effect with a detection limit of 0.10 ppm and good reusability, which demonstrates the first example of a MOF-based turn-on fluorescent sensor for acac.
