Background And Aims: Pancreas divisum (PD) is the most common developmental anatomic variant of pancreatic duct. The published data on the accuracy of the detection of pancreas divisum by linear-array endoscopic ultrasound (L-EUS) is limited. The current study aimed to assess the diagnostic accuracy of L-EUS compared with magnetic resonance cholangiopancreatography (MRCP) for identifying PD.

The role of gut microbiota (GM) dysbiosis in the pathogenesis of depression has received widespread attention, but the mechanism remains elusive. Corticosterone (CORT)-treated mice showed depression-like behaviors, reduced hippocampal neurogenesis, and altered composition of the GM. Fecal microbial transplantation from CORT-treated mice transferred depression-like phenotypes and their dominant GM to the recipients.

Article Synopsis
  • Acute pancreatitis (AP) is a serious condition that destroys pancreatic cells and causes inflammation, and researchers want to know if a cell death process called ferroptosis plays a role in it.* -
  • Scientists did experiments on both mice and pancreatic cells to see how certain metabolic processes changed during AP and how stopping ferroptosis could help reduce damage.* -
  • The results showed that a pathway called IDH2-NADPH can help protect pancreatic cells from ferroptosis and reduce the severity of AP, suggesting that targeting this pathway could lead to better treatments.*

Article Synopsis
  • Respiratory diseases in swine, caused by various viral and bacterial agents, impose significant economic impacts on the pork industry globally, highlighting the need for efficient pathogen detection methods.
  • * This research utilized a multiplex ligation-dependent probe amplification (MLPA) assay to detect seven specific respiratory pathogens in pigs, showing high sensitivity and reasonable specificity compared to existing PCR methods.
  • * Results from the study indicated that MLPA can accurately identify infections in swine, with a notable co-infection rate among the pathogens, making it a vital tool for disease management and surveillance in swine populations.

Article Synopsis
  • Ultrasonic treatment at varying power levels (0 to 600 W) significantly increased the extraction yield of collagen from albacore skin, achieving an 8.56% maximum improvement compared to traditional methods.
  • Analysis showed that using ultrasonic power above 300 W resulted in lower molecular weight peptides, but the collagen's triple helix structure remained intact.
  • The study found that collagen extracted at 150 W provided the best viscosity, indicating that ultrasonic powers between 150 and 300 W enhance collagen extraction and solution properties without damaging its structural integrity.*

Background: Pancreatic fibrosis is a hallmark feature of chronic pancreatitis (CP), resulting in persistent damage to the pancreas. The sustained activation of pancreatic stellate cells (PSCs) plays a pivotal role in the progression of pancreatic fibrosis and is a major source of extracellular matrix (ECM) deposition during pancreatic injury.

Methods: Calpain is a calcium-independent lysosomal neutral cysteine endopeptidase and was found to be correlated to various fibrotic diseases.

Ethnopharmacological Relevance: Herbal formulas from Traditional Chinese Medicine are common and well-established practice for treating acute pancreatitis (AP) patients. However, little is known about their bioactive ingredients and mechanisms, such as their targets and pathways to inhibit inflammation.

Aim Of The Study: This study aimed to evaluate the effect of Qing Xia Jie Yi Formula (QXJYF) granules on AP and discuss the molecular mechanisms involved.

Objective: There is an unmet clinical need for effective, targeted interventions to prevent post-ERCP pancreatitis (PEP). We previously demonstrated that the serine-threonine phosphatase, calcineurin (Cn) is a critical mediator of PEP and that the FDA-approved calcineurin inhibitors, tacrolimus (Tac) or cyclosporine A, prevented PEP. Our recent observations in preclinical PEP models demonstrating that Cn deletion in both pancreatic and hematopoietic compartments is required for maximal pancreas protection, highlighted the need to target both systemic and pancreas-specific Cn signaling.

Background: Brush cytology during endoscopic retrograde cholangiopancreatography (ERCP) is a standard approach in diagnosing biliopancreatic strictures, with yet unsatisfying sensitivity.

Aims: We brought additional simultaneous vacuum aspiration to brushing process and re-evaluate the diagnostic performance.

Methods: This multi-centered retrospective study was conducted in three tertiary centers.

Objectives: Retinol binding protein (RBP) is associated with an increased risk of insulin resistance, metabolic syndrome, atherosclerosis and hypertension. This study aimed to evaluate serum RBP levels in patients with acute pancreatitis (AP).

Methods: The study included 1,871 AP patients, including 1,411 with mild AP (MAP), 244 with moderately severe AP (MSAP), and 186 with severe AP (SAP).

Mucin-2 (MUC2) secreted by goblet cells participates in the intestinal barrier, but its mechanism in acute necrotizing pancreatitis (ANP) remains unclear. In acute pancreatitis (AP) patients, the functions of goblet cells (MUC2, FCGBP, CLCA1, and TFF3) decreased, and MUC2 was negatively correlated with AP severity. ANP rats treated with pilocarpine (PILO) (PILO+ANP rats) to deplete MUC2 showed more serious pancreatic and colonic injuries, goblet cell dysfunction, gut dysbiosis, and bacterial translocation than those of ANP rats.

Objective: There is an urgent need for safe and targeted interventions to mitigate post-ERCP pancreatitis (PEP). Calcineurin inhibitors (CnIs) offer therapeutic promise as calcineurin signaling within acinar cells is a key initiating event in PEP. In previous proof-of-concept studies using experimental models, we showed that concurrent intra-pancreatic ductal administration of the CnIs, tacrolimus (Tac) or cyclosporine A (CsA) with the ERCP radiocontrast agent (RC) prevented PEP.

Introduction: Endoscopic transmural drainage (TMD) has been accepted as the preferred therapy for symptomatic pancreatic fluid collections (PFCs). Recurrence of PFCs presents a unique challenge in patients with disrupted pancreatic duct (PD). We aimed to evaluate whether transpapillary drainage (TPD) provides additional benefits to TMD in patients with PD disruption.

Acinar cell death and inflammatory response are two important events which determine the severity of acute pancreatitis (AP). Endoplasmic reticulum (ER) stress and necroptosis are involved in this process, but the relationships between them remain unknown. Here, we analyzed the interaction between ER stress and necroptosis and the underlying mechanisms during AP.

Inflammation is one of the inducing factors of pancreatic ductal adenocarcinoma (PDAC), and microRNAs have been confirmed to be involved in the occurrence and development of PDAC. However, whether RELA, an inflammatory regulator, is involved in the regulation of PDAC by miRNA remains to be further studied. In the present study miR-21 was characterized and its upstream regulatory mechanism was investigated, as well as its functional effects and target genes in pancreatic ductal adenocarcinoma (PDAC).

There is increasing evidence that circular RNAs (circRNAs) can serve as microRNA (miRNA) sponges to regulate metastasis of multiple tumors, including pancreatic ductal adenocarcinoma (PDAC). However, the role of the circRNA/miRNA regulatory network in metastasis of PDAC has not been elucidated. The purpose of this study is to explore the role of circ_0047744/miR-21/SOCS5 in the metastasis of PDAC.

BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is a chronic, progressive liver disease with an increasing incidence rate. This study investigated the protective effects of live combined Bacillus subtilis and Enterococcus faecium (LCBE) on NAFLD, and its possible mechanisms. MATERIAL AND METHODS Five-week-old C57BL/6 mice were randomly divided into 3 groups: chow, HFD, and HFD+LCBE groups.

Acute pancreatitis (AP) is associated with impaired acinar cell autophagic flux, intracellular zymogen activation, cell necrosis and inflammation. Activation of the cholinergic system of vagus nerve has been shown to attenuate AP, but the effect of organ-intrinsic cholinergic system on pancreatitis remains unknown. In this study, we aim to examine the effect of α7 nicotinic acetylcholine receptor (α7nAChR) stimulation within the pancreas during AP.

Background And Purpose: Macrophage infiltration and activation is a critical step during acute pancreatitis (AP). We have shown that pancreas-specific D receptor signalling protects against AP severity. As it is unclear to what extent myeloid-specific D receptor mediates AP, we investigated the role of myeloid-specific D receptor signalling in AP.
