Artificial intelligence contouring in radiotherapy for organs-at-risk and lymph node areas.

Introduction: The delineation of organs-at-risk and lymph node areas is a crucial step in radiotherapy, but it is time-consuming and associated with substantial user-dependent variability in contouring. Artificial intelligence (AI) appears to be the solution to facilitate and standardize this work. The objective of this study is to compare eight available AI software programs in terms of technical aspects and accuracy for contouring organs-at-risk and lymph node areas with current international contouring recommendations.

Ameliorative effect of Ononis natrix against chronic lead poisoning in mice: neurobehavioral, biochemical, and histological study.

Lead (Pb) is one of the most common heavy metals with toxicological effects on many tissues in humans as well as animals. In order to counteract the toxic effects of this metal, the administration of synthetic or natural antioxidants is thus required. The aim of this study was to examine the beneficial effect of the aqueous extract of Ononis natrix (AEON) against lead acetate-induced damage from a behavioral, biochemical, and histological point of view.

[Management of the Central Venous Catheter in Patients Undergoing Hemodialysis Treatment].

Catheter-related bloodstream infection (CRBSI) is defined as the presence of bacteremia originating from a venous catheter and is one of the most common and costly complications, often followed by death and septicemia. To evaluate the effectiveness of specific interventions on CRBSI reduction rates and other outcomes. Materials and Methods.
