Title:Glucagon and insulin immunopositivity of mast cells in porcine gallbladder
Author:Stefanov, I.; Stefanov, S.; Gulubova, M.Date:2024Abstract:It is well known that mast cells produce and release biologically active substances such as histamine, heparin, proteases, leukotrienes, cytokines, chemokines and growth factors. According to the available scientific literature on that topic this is the first time when gallbladder mast cells were found to have a capacity to produce insulin ...Library:

Title:Feline gastric adenocarcinoma – a clinical case
Author:Simeonov, R.; Krastev, S.; Hristov, Ts.Date:2024Abstract:Gastric adenocarcinomas are encountered exceptionally infrequently in cats. Some studies have claimed a predisposition in Siameses, while others affirm no relation to the breed. In veterinary literature, only few cases of feline gastric adenocarcinoma (FGA) are reported, which accounts for about 1% of all feline gastrointestinal adenocarcinomas. ...Library:
