The Home-Cage Automated Skilled Reaching Apparatus (HASRA): Individualized Training of Group-Housed Mice in a Single Pellet Reaching Task.

The single pellet reaching task is commonly used in rodents to assess the acquisition of fine motor skill and recovery of function following nervous system injury. Although this task is useful for gauging skilled forelimb use in rodents, the process of training animals is labor intensive and variable across studies and labs. To address these limitations, we developed a single pellet reaching paradigm for training and testing group housed mice within their home cage.

Diagnostic Accuracy of Dual-Energy CT for Evaluation of Renal Masses: Systematic Review and Meta-Analysis.

Objective: The purpose of this study is to determine the diagnostic accuracy of dual-energy CT (DECT) using quantitative iodine concentration in patients with renal masses using histopathologic analysis or follow-up imaging as the reference standard. The secondary objective is to compare the accuracy of DECT (using iodine concentration) to that of conventional CT (using Hounsfield unit measurements).

Materials And Methods: We searched the MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases for studies evaluating the accuracy of DECT for renal mass characterization (1947-2018).
