Advanced Materials, EarlyView.Upconversion nanoparticle‐covalent organic framework core–shell particles provide enhanced contrast for optoacoustic imaging by leveraging the optical absorption of upconversion luminescence within the covalent organic framework matrix. Beyond their role as contrast agents, these particles enable customizable therapeutic agent loading and release, as ...

Augmented anastomotic urethroplasty with ventrally placed buccal mucosal graft
Journal of the Scientific Society, 2020 The most common site of anterior urethral stricture is the bulbar urethra. The etiology of these strictures could be either idiopathic (40%), iatrogenic (35%), inflammatory (10%), or traumatic (15%) causes.

Miniaturized Devices for On‐the‐Spot Generation of Small‐Diameter Vascular Grafts
Advanced Materials Technologies, EarlyView.An intracorporeal extrusion device is developed for on‐the‐spot generation of vascular grafts with tunable diameters spanning from 1 to 6 mm. The device uses biomimetic polymers and light, to promptly obtaining biocompatible and high‐burst pressure‐resistant grafts.

Constructing solutions for a kinetic model of angiogenesis in annular domains [PDF]
Applied Mathematical Modelling 45, 303-322, 2017, 2016 We prove existence and stability of solutions for a model of angiogenesis set in an annular region. Branching, anastomosis and extension of blood vessel tips are described by an integrodifferential kinetic equation of Fokker-Planck type supplemented with nonlocal boundary conditions and coupled to a diffusion problem with Neumann boundary conditions ...

Annals of Gastroenterological Surgery, EarlyView.This retrospective study investigated risk factors for surgical site infections (SSIs) in right‐sided colon cancer surgeries using intracorporeal anastomosis (IA). The results demonstrated that preoperative oral antibiotics (OA) significantly reduced SSI rates, with OA identified as an independent protective factor, suggesting its beneficial role in ...

Deep learning-based computer vision to recognize and classify suturing gestures in robot-assisted surgery [PDF]
arXiv, 2020 Our previous work classified a taxonomy of suturing gestures during a vesicourethral anastomosis of robotic radical prostatectomy in association with tissue tears and patient outcomes. Herein, we train deep-learning based computer vision (CV) to automate the identification and classification of suturing gestures for needle driving attempts.
