Oxidative stress plays a major role in acute pancreatitis (AP), leading to massive macrophage infiltration. Nanoyttria (NY) possesses potent free radical scavenging activity. As reactive oxygen species and inflammation play major role in AP, we hypothesized that NY may alleviate cerulein induced AP. NY ameliorated LPS induced oxidative stress in vitro. It reduced ROS, superoxide radical generation and restored the mitochondrial membrane potential in macrophages. Interestingly, NY reduced plasma amylase and lipase levels and attenuated the mitochondrial stress and inflammatory markers. NY suppressed the recruitment of inflammatory cells around the damaged pancreatic acinar cells. Furthermore, NY intervention perturbed the course of AP via reduction of endoplasmic reticulum (ER) stress markers (BiP, IRE1 and Ero1-Lα), and molecular chaperones (Hsp27 and Hsp70). We, to the best of our knowledge, report for first time that NY can attenuate experimental AP by restoration of mitochondrial and ER homeostasis through Nrf2/NFκB pathway modulation.
The retrospective study by Lew (2022) examined the rising hospitalization rates for chronic pancreatitis (CP) and its association with pancreatic ductal adenocarcinoma (PDAC), revealing significant ethno-racial disparities and risk factors. Overweight black men aged 40-59 years and white men over 40 years with higher incomes showed an elevated risk of PDAC among CP patients. The study, which included 14.
Background: Endogenous glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) regulate islet cell function. GLP-1 receptor agonists (GLP-1RAs) have been associated with an elevated risk of acute pancreatitis. Data on the pancreatic safety of tirzepatide (a dual GLP-1 and GIP agonist) and its effects on islet cell function in randomized controlled trials (RCTs) are scarce.
The causal relationship between inflammatory factors and acute pancreatitis (AP), chronic pancreatitis (CP), alcohol-induced acute pancreatitis (AAP), and alcohol-induced chronic pancreatitis (ACP) remains unclear. We aimed to examine the casual relationship between inflammatory factors and various forms of pancreatitis, namely, AP, CP, AAP, and ACP. We employed a two-sample Mendelian randomization (MR) analysis to investigate the causal relationship between 91 inflammatory factors and 41 inflammatory factors with respect to pancreatitis.
Introduction: The late autumn epizootic of the highly pathogenic avian influenza virus (HPAIV) subtype H5N1 in Serbia in 2023 caused massive mortality in the migratory population of common cranes (). This is the first time HPAIV has been identified in the common crane in Serbia, leading to mass mortality of this bird species.
Methods: To understand the pathological impact of HPAIV in cranes, we evaluated the pathological changes in the tissues of common cranes.
Acute pancreatitis, a sudden inflammatory condition, can lead to a hypercoagulable state resulting in complications such as deep vein thrombosis (DVT) or pulmonary embolism (PE). This case report discusses a unique presentation of a massive PE in a patient with acute pancreatitis despite being on appropriate prophylactic anticoagulation. A 27-year-old man presented with acute abdominal pain, nausea, and vomiting.
