Investigating the 'Uncatchable Smile' in Leonardo da Vinci's La Bella Principessa: A Comparison with the Mona Lisa and Pollaiuolo's Portrait of a Girl

This paper discusses the methodology used to reveal the 'Uncatchable Smile' illusion in Leonardo da Vinci's La Bella Principessa portrait. A combination of three methods was used (inter-observation, structured interviews, and psychophysical experiments), which led to an investigation that shaped itself without prior beliefs, thus reducing potential researcher...

ROS Detection with DCFH-DA Staining: Measuring Total ROS in Colorectal Cancer Cell Lines03:50

ROS Detection with DCFH-DA Staining: Measuring Total ROS in Colorectal Cancer Cell Lines

This video describes the protocol for detecting total cellular reactive oxygen species (ROS) using 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA). This method helps visualize ROS localization in the adherent cells using a fluorescence microscope and further quantify ROS intensity with a fluorescence plate...

Subcostal Specimen Removal in Completely Portal Robotic Lobectomy04:38

Subcostal Specimen Removal in Completely Portal Robotic Lobectomy

This protocol describes the removal of lung specimens following a completely portal robotic lobectomy. Determining the optimal location for specimen extraction is a pertinent question, as both intercostal and subcostal routes can serve as potential extraction paths following robotic or video-thoracoscopic lobectomy. We choose subcostal lung specimen removal over intercostal...

Direct Restart of a Replication Fork Stalled by a Head-On RNA Polymerase07:27

Direct Restart of a Replication Fork Stalled by a Head-On RNA Polymerase

The fate of the replisome following a collision with a head-on RNA polymerase (RNAP) is unknown. We find that the replisome stalls upon collision with a head-on RNAP, but resumes elongation after displacing the RNAP from DNA. Mfd promotes replication restart by facilitating displacement of the RNAP after the...
