In experiments on dogs the exocrine secretion of pancreatic segment graft after its autotransplantation and of pancreatic stamps after proximal resection of the pancreas was investigated. More significant impairment of the exocrine secretion of the pancreas was revealed in animals after pancreatic graft autotransplantation in comparison with animals after the proximal resection of the pancreas. Maintenance of the adaptation of pancreatic exocrine secretion to the nutritional composition of the intestinal contents and "generalized inhibition" of pancreatic exocrine secretion caused by duodenal trypsin infusion was revealed in all groups.

Background: Cancer-associated venous thromboembolism (CAT) is a frequent and serious complication in cancer patients. Resveratrol, a natural compound with reported anti-tumor effects, is not fully understood in its role regarding CAT in lung cancer. This study aims to explore resveratrol's potential to diminish platelet activation induced by lung adenocarcinoma cells and uncover the underlying mechanisms.

Objective: To investigate the central sensitization (CS) in patients with autoimmune connective tissue diseases (ACTDs) and its relationship with disease activity, laboratory findings, medical treatments, organ involvements, and comorbidity.
Methods: One hundred and eleven patients with ACTDs and 40 healthy individuals were included. All patients were divided into three groups in terms of their diseases: Sjögren's syndrome (SS), rheumatoid arthritis (RA), and systemic lupus erythematosus (SLE).
Minimally invasive versus open lateral pancreaticojejunostomy in patients with painful chronic pancreatitis: systematic review.

Department of Surgery, Amsterdam UMC, location University of Amsterdam, Amsterdam, The Netherlands.
Background: Patients with painful chronic pancreatitis combined with a dilated main pancreatic duct and a normal size pancreatic head are treated according to guidelines by lateral pancreaticojejunostomy (LPJ). This systematic review compared outcomes of minimally invasive LPJ and open LPJ.
Methods: From 1 January 2000 until 13 November 2023, series reporting on minimally invasive LPJ and open LPJ in patients with symptomatic chronic pancreatitis were included.
Unraveling the Connection Between Ion Channels and Pancreatic Stellate Cell Activation.

Quiescent pancreatic stellate cells (PSCs) represent only a very low proportion of the pancreatic tissue, but their activation leads to stroma remodeling and fibrosis associated with pathologies such as chronic pancreatitis and pancreatic ductal adenocarcinoma (PDAC). PSC activation can be induced by various stresses, including acidosis, growth factors (PDGF, TGFβ), hypoxia, high pressure, or intercellular communication with pancreatic cancer cells. Activated PSC targeting represents a promising therapeutic strategy, but little is known regarding the molecular mechanisms underlying the activation of PSCs.

Pancreatic cancer (PC) is one of the most aggressive malignancies, characterized by an increasing incidence and unfavorable prognosis. Despite recent advances, surgical resection combined with chemotherapy remains the only potentially curative therapeutic option. Therefore, it is of paramount importance to identify novel therapeutic targets and develop effective treatment strategies.
