1. Deve-se fazer “screening” para colangiocarcinoma em pacientes com história familiar positiva para esta neoplasia?
Não foram encontrados Ensaios Clínicos Randomizados que demonstrassem a superioridade ou não do screening para colangiocarcinoma em relação à observação clínica. De acordo com especialistas, não há indicação de screening para colangiocarcinoma, mesmo entre os indivíduos com história familiar da doença. Há consenso entre os especialistas d

2. Atorvastatina Reduz o Acúmulo de Células Musculares Lisas Vasculares para Inibir a Hiperplasia Intimal pela Inibição de Via p38 MAPK em um Modelo de Enxerto de Veia em Ratos
Resumo Fundamento: A taxa de falha de enxerto de veia safena um ano após a cirurgia de revascularização do miocárdio varia de 10% a 25%. O objetivo deste estudo foi de investigar se a atorvastatina pode reduzir o acúmulo de células musculares lisas vasculares para inibir a hiperplasia intimal por meio da inibição da via p38 MAPK. Métodos: Quarenta

4. ARMC5 mutations are associated with high levels of proliferating cell nuclear antigen and the presence of the serotonin receptor 5HT4R in PMAH nodules
ABSTRACT Objective To analyze the morphological and functional characteristics of primary macronodular adrenal hyperplasia (PMAH) nodules carrying or not carrying ARMC5 mutations and the consequences of the presence of mutations in terms of the pattern of macronodule composition and functional state. Subjects and methods The analyses were performed by he

5. Inhibitory effects of tanshinone IIA from Salvia miltiorrhiza Bge on human bladder cancer BIU-87 cells and xenograft in nude mice
Abstract The objective of this study was to investigate the inhibitory effects of tanshinone IIA on human bladder cancer BIU-87 cells and the xenograft in nude mice. BIU-87 cells were treated with tanshinone IIA with concentration of 0.5, 1, 2 and 4 g/L. The cell proliferation, cycle and apoptosis were detected. The nude mice with BIU-87 cell xenograft were

6. Assessment of remnant liver function and volume after selective ligation of portal vein and hepatic artery in a rat model
Abstract Purpose: To evaluate liver regeneration after selective ligation of portal vein and hepatic artery by 3D Computed Tomography in an experimental model. Methods: Sixteen Wistar rats were randomized into four equal groups: Group I- control (sham), Group II- isolated selective ligation of the hepatic artery, Group III- isolated selective ligation of t

7. Total Panax notoginseng saponin inhibits balloon injury-induced neointimal hyperplasia in rat carotid artery models by suppressing pERK/p38 MAPK pathways
Total Panax notoginseng saponin (TPNS) is the main bioactivity compound derived from the roots and rhizomes of Panax notoginseng (Burk.) F.H. Chen. The aim of this study was to investigate the effectiveness of TPNS in treating vascular neointimal hyperplasia in rats and its mechanisms. Male Sprague-Dawley rats were randomly divided into five groups, sham (co

10. Pine ( Pinus densiflora ) needle extract could promote the expression of PCNA and Ki-67 after partial hepatectomy in rat
Abstract Purpose To investigate the effects of pine needle extract (PNE) on the expression of proliferating cell nuclear antigen (PCNA) and Ki-67 during liver regeneration induced by 70% partial hepatectomy (PH) in rat. Methods Forty-eight male rats (SD, 7 weeks) had surgery (70% PH). They were randomly divided into two groups. PH + PNE group was only prov

11. Cholecystectomy during ceftriaxone therapy. A translational study with a new rabbit model
Abstract Purpose: To evaluate the actual incidence of both microlithiasis and acute cholecystitis during treatment with intravenous ceftriaxone in a new rabbit model. Methods: New Zealand rabbits were treated with intravenous ceftriaxone or saline for 21 days. Ultrasound monitoring of the gallbladder was performed every seven days until the 21st day when

12. Propofol attenuates cytokine-mediated upregulation of expression of inducible nitric oxide synthase and apoptosis during regeneration post-partial hepatectomy
Abstract Purpose: To determine the effects of propofol and ketamine anesthesia on liver regeneration in rats after partial hepatectomy (PHT). Methods: Male Wistar albino rats were assigned randomly to four groups of 10. Anesthesia was induced and maintained with propofol in groups 1 and 2, and with ketamine in groups 3 and 4. PHT was undertaken in groups 1
