Ischemia-reperfusion injury (IRI) is a serious complication of hepatectomy and liver transplantation. The aim of this study was to evaluate the protective effects of salvianolic acid-A (Sal-A) against IRI-induced hepatocellular injury. ⋯ Sal-A had a synergistically protective effect on the liver tissue against IRI that might be due to decreased oxidative stress, inflammation, hepatocellular apoptosis and include, at least in part, the regulation of TLR4.

The aim of the study was to retrospectively evaluate the technical features, efficacy, accuracy, and relevant complications of computed tomography-guided biopsies in various anatomical localizations when diagnosing indolent lymphoma transformations, relapses, duplicate malignant diseases or benign processes. ⋯ Percutaneous CT guided biopsy performed in patients with a history of indolent lymphoma had high accuracy in establishing the correct diagnosis regarding transformation, relapse, duplicate malignancy or a benign process. Simultaneously, the complication rate was low.

Liver biopsy is a well-known method for the diagnosis and evaluation of chronic diffuse liver diseases, especially among patients with "hepatopathy of unknown origin". ⋯ Liver biopsy - despite the increasing access to new, non-invasive methods - remains a useful method in the differential diagnosis of liver diseases.

Neointimal hyperplasia due to smooth muscle cell migration and proliferation, as well as extracellular matrix accumulation, plays an important role in stenosis and restenosis that develop after reconstructive vascular interventions. Various agents are being tested to reduce neointimal hyperplasia and to prevent lumen stenosis. In the present study, the effect of N-acetylcysteine (NAC) on intimal hyperplasia and endothelial hyperplasia after carotid anastomosis was investigated in a rabbit model. ⋯ We believe that vascular anastomosis and post-intervention NAC administration will prolong vascular patency by reducing intimal hyperplasia and providing vascular remodeling.

Recent studies have shown that long non-coding RNAs (lncRNAs) are involved in a variety of biological processes and diseases in humans, including cancer. However, the exact effects and molecular mechanisms of TP73-AS1 in non-small cell lung cancer (NSCLC) progression are still unknown. The present study is aimed to reveal the detailed functions and the mechanism of TP73-AS1 in the regulation of NSCLC cell proliferation. ⋯ Our data suggest that TP73-AS1 might be an oncogenic lncRNA that promotes proliferation of NSCLC and might be regarded as a therapeutic target in NSCLC.
