1. Molecular mechanism of benign biliary stricture inhibition by rosiglitazone-activated peroxisome proliferator-activated receptor gamma
SUMMARY OBJECTIVE: The aim of this study was to investigate whether rosiglitazone-activated peroxisome proliferator-activated receptor gamma can inhibit the occurrence of benign biliary stricture and further elucidate the relevant molecular signaling mechanism. METHODS: The primary cultured rat biliary fibroblasts following experiments were performed using

2. The role of gadoxetic acid-enhanced magnetic resonance cholangiography in the evaluation of postoperative bile duct injury: pictorial essay
Resumo As lesões iatrogênicas das vias biliares são relativamente frequentes e aumentam as taxas de morbidade e mortalidade pós- operatória. A colangiografia por ressonância magnética ponderada em T2 e as imagens hepatobiliares funcionais com ácido gadoxético (CRM-F) são fundamentais na abordagem diagnóstica desses pacientes. Os autores apresentam

4. Blood parameters and hepatic histopathology of broilers fed rations supplemented with essential oils
ABSTRACT This study aimed to evaluate the hematological profile, hepatic function, and histopathology of mixed-sex broilers fed rations supplemented with microencapsulated essential oils from Cymbopogon flexuosus (lemon grass) and Lippia rotundifolia (chá-de-pedestre). One hundred and fifty Cobb chicks were housed in cages from 1 to 42 days of age in a comp

6. An evaluation of the protective effect of an infusion of chilled glucose solution on thermal injury of the bile ducts caused by radiofrequency ablation of the liver
PURPOSE:To evaluate the protective effects of chilling the bile ducts with cold (5°C) 5% glucose solution (GS) during radiofrequency (RF) administration.METHODS:Twenty male pigs (3 mos. old; 25-30 kg) were subjected to RF delivery with chilling (experimental group, N=10) or without chilling (control group, N=10). Half of the animals in each group were eutha

7. Liver transplantation for neotropical polycystic echinococcosis caused by Echinococcus vogeli: a case report
Neotropical polycystic echinococcosis (NPE) is a parasitic disease caused by cestodes of Echinococcus vogeli. This parasite grows most commonly in the liver, where it produces multiples cysts that cause hepatic and vessel necrosis, infects the biliary ducts, and disseminates into the peritoneal cavity, spreading to other abdominal and thoracic organs. In cas

8. Tamoxifen decreases the myofibroblast count in the healing bile duct tissue of pigs
OBJECTIVE: The aim of this study was to evaluate the effect of oral tamoxifen treatment on the number of myofibroblasts present during the healing process after experimental bile duct injury. METHODS: The sample consisted of 16 pigs that were divided into two groups (the control and study groups). Incisions and suturing of the bile ducts were performed in th

9. Histopathological diagnosis of intra- and extrahepatic neonatal cholestasis
The histopathology of the liver is fundamental for the differential diagnosis between intra- and extrahepatic causes of neonatal cholestasis. However, histopathological findings may overlap and there is disagreement among authors concerning those which could discriminate between intra- and extrahepatic cholestasis. Forty-six liver biopsies (35 wedge biopsies

10. Alterações hepatobiliares em gatos domésticos (Felis catus domesticus) parasitados por Platynosomum illiciens (Braun, 1901) Kossack, 1910 observadas através do exame radiográfico, ultra-sonográfico e de tomografia computadorizada. / Hepatobiliary changes in domestic cats (Felis catus domesticus) infected by Platynosomum illiciens (Braun, 1901) Kossack, 1910 observed through radiography, ultrasound and computed tomography.
Platynosomum illiciens (Braun 1901) Kossack, 1910, considered by some authors as synonymy of Platynosomum fastosum and Platynosomum concinnum, is the most important trematode found in cats of tropical and subtropical areas, and its prevalence can reach up to 85%. In Brazil it was already found at different localities, but State of Rio de Janeiro is where it

11. Influence of connexin 43 expression in biliaries ducts hyperplasia, after biliary common duct obstruction (coledoco) model in mice with deletion of one allele of the connexin / Influência da expressão da conexina 43 em modelo de hiperplasia de ductos biliares, após a ligação do ducto biliar comum (colédoco), em camundongos com deleção em um dos alelos para o gene da conexina 43
Atualmente, as pesquisas sobre a as células epiteliais biliares expressam uma grande quantidade de conexina 43. O presente estudo avaliou influência do genótipo de camundongos Cx 43 +/- ou Cx 43 +/+, sobre a hiperplasia de ductos biliares, após a ligação do ducto biliar comum (colédoco). Neste estudo, foram utilizados seis grupos de camundongos BALB/c

12. Lesão complexa da via biliar principal: a ligadura como opção associada a colecistojejunostomia
The authors present a case of distal common bile duct injury. Ligation of the bile duct and a bypass cholecystojejunostomy were chosen as treatment. Diagnosis of blunt traumatic injury to the extrahepatic biliary ducts may be difficult due to the benign nature of initial bile peritonitis. Surgical treatment for associated abdominal injuries usually makes the
