Regadenoson Stress Testing: A Comprehensive Review With a Focused Update.

Regadenoson is a pharmacological stress agent that has been widely used since its approval by the Food and Drug Administration (FDA) in 2008. For many years, dipyridamole and adenosine, which are non-selective adenosine receptor agonists, were more popular. However, these agents are less preferred now due to their undesirable adverse effects as compared to regadenoson.

Analysis of surgically treated gastric cancers: a tertiary hospital experience in Turkey.

Objective: Gastric cancer (GC) is the fifth most common cancer worldwide, and in Turkey, GC is placed among the 10 most frequently seen cancers. However, analyzing the epidemiology of cancers and improving screening programs for cancers are not still the top priorities for healthcare professionals. This study aims to show distribution of GC based on stages in a tertiary hospital of Istanbul, Turkey.

Effects of N-acetylcysteine on regeneration following partial hepatectomy in rats with nonalcoholic fatty liver disease.

Purpose: To investigate the effect of N-acetylcysteine on regeneration following partial hepatectomy in rats with nonalcoholic fatty liver disease (NAFLD).

Methods: N-Acetylcysteine was given to seven rats with NAFLD (group 1); physiological saline was given to seven rats with NAFLD (group 2); and physiological saline was given to seven rats with a normal liver (group 3). We performed two-thirds hepatectomy in all rats and removed the remnant liver tissue 48 h later to measure the mitotic index (MI), proliferating cell nuclear antigen, glutathione (GSH), and malondialdehyde (MDA) levels.

The effect of ursodeoxycholic acid on liver regeneration after partial hepatectomy in rats with non-alcoholic fatty liver disease.

Aim: To investigate the effect of ursodeoxycholic acid (UDCA) on liver regeneration following partial hepatectomy in rats with non-alcoholic fatty liver disease (NAFLD).

Methods: UDCA was administered to seven rats (group 1) and physiological saline was administered both to seven rats (group 2) with NAFLD and to seven rats with normal livers (group 3). All rats underwent two-thirds hepatectomy and the remnant liver tissues were removed 48 h later.
