Effects of Recombinant Human Erythropoietin and 2-Mercaptoethane Sulfonate on Liver Ischemia-Reperfusion Injury in Rats.

Objectives: The aim of this study was to determine the effects of recombinant human erythropoietin and 2-merkaptoethane sulfonate, administered in combination, on the biochemical and histopathological changes of ischemia-reperfusion injury.

Materials And Methods: Fifty female Wistar Albino rats were used in this study. The animals were randomly divided into 5 groups: a sham group that underwent standard laparotomy only, an ischemia-reperfusion group that was subjected to 30 minutes of hepatic ischemia and 2 hours of reperfusion, a group that intraperitoneally received 1000 IU/kg recombinant human erythropoietin 5 minutes before ischemiareperfusion, a group that intraperitoneally received 150 mg/kg 2-merkaptoethane sulfonate 15 minutes before ischemia-reperfusion, and a combined group that received both drugs intraperitoneally before ischemia-reperfusion.

Routine Use of Prophylactic Antibiotics during Laparoscopic Cholecystectomy Does Not Reduce the Risk of Surgical Site Infections.

Background: Laparoscopic cholecystectomy (LC) is the gold standard for the treatment of symptomatic gallbladder stones. As infections are rare in uncomplicated LC, it is widely accepted that prophylactic antibiotics need not be administered, and guidelines do not support routine antibiotic prophylaxis during elective LC. However, routine antibiotic prophylaxis for elective LC is still popular in many clinical settings.

Impact of 3'UTR variation patterns of the KRAS gene on the aggressiveness of pancreatobiliary tumors with the KRAS G13D mutation in a Turkish population.

Objective: Several studies have demonstrated the importance of mutations in codons 12, 13 and 61 and variations in the 3' untranslated region (3'UTR) of the KRAS gene, frequently observed genetic events in the progression of pancreatobiliary tumors (PBT). However, limited data exist on the clinical effect of these alterations. The aim of the current study was to clarify the frequency of relevant alterations of the 3'UTR regions of the KRAS gene and the effect of KRAS 3'UTR polymorphisms on the prognosis of patients with codon 12, 13 and 61 mutations in a Turkish population with PBT.

miR-216b Targets FGFR1 and Confers Sensitivity to Radiotherapy in Pancreatic Ductal Adenocarcinoma Patients Without EGFR or KRAS Mutation.

Objectives: The success of gemcitabine plus radiotherapy is dependent on the mutation status of pancreatic ductal adenocarcinoma (PDAC) tumors in the EGFR and KRAS genes; however, radiotherapy resistance may also be modulated epigenetically by microRNA (miRNA) regulation. In this study, we examined the potential effect of miRNAs on the resistance to radiotherapy in cases without EGFR or KRAS mutation.

Methods: The association of EGFR and KRAS mutation status and different expression patterns of 6 selected miRNAs related to the EGFR/KRAS signaling pathway were evaluated in the tumors of 42 patients with PDAC.

Early graft dysfunction and mortality rate in marginal donor liver transplantation.

Background/aim: To determine the effect of marginal donor livers on mortality and graft survival in liver transplantation (LT) recipients.

Materials And Methods: Donors with any 1 of following were considered marginal donors: age ≥65 years, sodium level ≥ 165 mmol/L and cold ischemia time ≥ 12 h. Donors were classified according to the donor risk index (DRI) < 1.

Staged abdominal repair in the treatment of intra-abdominal infection: analysis of 102 patients.

Surgical treatment of intra-abdominal infections remains a challenge for the surgeon. Staged abdominal repair is being commonly used in patients with intra-abdominal infections. This study presents our experience with staged abdominal repair and analyzes factors affecting mortality.
