We report two cases of paraganglioma in which the tumour was situated adjacent to the head of the pancreas simulating a pancreatic mass lesion. The absence of biliary or pancreatic duct dilatation on ultrasound in the presence of a large mass suggested a retroperitoneal tumour rather than a pancreatic adenocarcinoma. Functional activity in these tumours is common and should be excluded before biopsy.

Silver nanoparticles (AgNPs) are spherical particles with a number of specific and unique physical (such as surface plasmon resonance, high electrical conductivity and thermal stability) as well as chemical (including antimicrobial activity, catalytic efficiency and the ability to form conjugates with biomolecules) properties. These properties allow AgNPs to exhibit desired interactions with the biological system and make them prospective candidates for use in antibacterial and anticancer activities. AgNPs have a quenching capacity, which produces reactive oxygen species and disrupts cellular processes (such as reducing the function of the mitochondria, damaging the cell membrane, inhibiting DNA replication and altering protein synthesis).

Pro-inflammatory cytokines, like interleukin-1 beta and interferon gamma, are known to activate signalling pathways causing pancreatic beta cell death and dysfunction, contributing to the onset of diabetes. Targeting cytokine signalling pathways offers a potential strategy to slow or even halt disease progression, reducing reliance on exogenous insulin and improving glucose regulation. This study explores the protective and proliferative effects of breitfussin C (BfC), a natural compound isolated from the Arctic marine hydrozoan Thuiaria breitfussi, on pancreatic beta cells exposed to pro-inflammatory cytokines.

Pancreatic ductal adenocarcinoma (PDAC) organoids that simulate the tumor microenvironment (TME) are an effective tool to identify how TME affects PDAC malignancy. We present a protocol for generating a fused pancreatic cancer organoid (FPCO) that partly reproduces the TME, including heterogeneous cancer-associated fibroblasts (CAFs), using patient-derived PDAC cells and human-induced pluripotent cell-derived endothelial and mesenchymal cells. We also describe the procedure for analyzing FPCO characteristics.

: Pathophysiological variability in patients with cancer is associated with differences in responses to pharmacotherapy. In this work, we aimed to describe the demographic characteristics and hematological, biochemical, and coagulation variables in a large oncology cohort and to develop, optimize, and provide open access to modeling equations for the estimation of variables potentially relevant in pharmacokinetic modeling. : Using data from 1793 patients with cancer, divided into training ( = 1259) and validation ( = 534) datasets, a modeling network was developed and used to simulate virtual oncology populations.

A series of novel carnosic acid derivatives incorporating urea moieties at the C-20 position was synthesized and evaluated for their antiproliferative activity against the HCT116 colorectal cancer cell line. Most derivatives demonstrated enhanced antiproliferative activity compared to that of carnosic acid . The most promising derivatives were tested in other colorectal cancer cell lines (SW480, SW620, and Caco-2), melanoma (A375), and pancreatic cancer (MiaPaca-2).
