AI Article Synopsis

  • * Trials were conducted comparing the performance of experienced surgeons to novices in a surgical model, measuring targeting accuracy and force applied during these steps.
  • * Results showed experienced surgeons performed better in targeting, causing less movement of the prosthesis, which is crucial for successful surgery and can impact hearing results.

Article Abstract

Objectives: Two steps in stapedotomy are particularly challenging: (1) micropick fenestration of the stapes footplate (SF) and (2) crimping of the stapes prosthesis (SP) to the incus. We conducted trials to determine if experience correlates with differences in performance for these tasks.

Methods: In a surgical model of stapedotomy, performance was measured for 3 experienced and 3 novice surgeons. For fenestration, we measured ability to target the fenestration and force applied to the SF. For crimping, we measured crimp quality, movement of the SP during crimping, and force applied to the SF.

Results: Experienced surgeons demonstrated significantly better ability to target the fenestration and, during crimping, caused less SP movement and a significantly lower rate of SP dislodgment.

Conclusions: Clear differences in task performance are measurable between more and less experienced surgeons during critical steps of stapedotomy.

Clinical Significance: The observed differences in task performance may contribute to an understanding of maneuvers that increase the risk of inadequate prosthesis placement and cochlear trauma-factors likely responsible for variable hearing results with strapedotomy.

Background: Medical imaging plays a pivotal role in the real-time monitoring of patients during the diagnostic and therapeutic processes. However, in clinical scenarios, the acquisition of multi-modal imaging protocols is often impeded by a number of factors, including time and economic costs, the cooperation willingness of patients, imaging quality, and even safety concerns.

Purpose: We proposed a learning-based medical image synthesis method to simplify the acquisition of multi-contrast MRI.

Rapid identification of asparagine (Asn) deamidation and isoaspartate (Asp) in proteins remains a challenging analytical task during the development of biological therapeutics. For this study, 46 therapeutically relevant peptides corresponding to 13 peptide families (13 unmodified peptides and 33 modified peptides) were obtained; modified peptides included Asn deamidation and isoAsp. The peptide families were characterized by three methods: reversed-phase ultrahigh performance liquid chromatography-mass spectrometry (RP-UHPLC-MS); flow injection analysis high-resolution ion mobility-mass spectrometry (FIA-HRIM-MS); and shortened gradient RP-UHPLC-HRIM-MS.

The alkaline oxygen evolution reaction (OER) mainly encompasses four elementary reactions, involving intermediates such as HO*, O*, and HOO*. Balancing the Gibbs free energies of these intermediates at a single active site is a challenging task. In this work, a high-entropy metal-organic framework incorporating Fe, Ni, Co, Cu, and Y metal elements is synthesized using an electrodeposition method, which then serves as a template for preparing a high-entropy phosphide/carbon (FeCoNiCuYP/C) composite.

Generating molecules that bind to specific proteins is an important but challenging task in drug discovery. Most previous works typically generate atoms autoregressively, with element types and 3D coordinates of atoms generated one by one. However, in real-world molecular systems, interactions among atoms are global, spanning the entire molecule, leading to pair-coupled energy function among atoms.
