Comparison of the pull-out force of different microtube-based methods in fractured endodontic instrument removal: An in-vitro study.
BMC Oral Health
January 2025
Department of Endodontics, School of Dentistry, Tehran University of Medical Sciences, Tehran, Iran.
Background: The fracture of an endodontic instrument within the root canal system can occur during root canal therapy, complicating thorough cleaning and shaping. Consequently, managing the broken fragment becomes crucial.
Methods: Eighty Nickel-titanium (NiTi) #20 K-files (Mani, Tochigi, Japan) were cut 8 mm from the tip, fixed into a corkboard, and classified into five groups (n = 14 each).
Long-term efficacy and catheter choice in male varicocele embolization using NBCA-MS glue.
Int Urol Nephrol
December 2024
Department of Diagnostic and Interventional Radiology, IRCCS Humanitas Research Hospital, Via Manzoni 56, 20089, Rozzano, Milan, Italy.
Purpose: This study investigated the long-term efficacy of n-butyl-2-cyanoacrylate-metacryloxysulpholane (NBCA-MS) for varicocele embolization (VE) without using a microcatheter.
Methods: A retrospective study was conducted on male patients who underwent VE with NBCA-MS for grade III-IV varicocele between January 2016 and December 2022. Patients were categorized by the catheter type used.
A Novel Method for the Generation of Realistic Lung Nodules Visualized Under X-Ray Imaging.
Tomography
December 2024
Department of Radiology, University of Massachusetts Medical Center, Worcester, MA 01655, USA.
Objective: Image-guided diagnosis and treatment of lung lesions is an active area of research. With the growing number of solutions proposed, there is also a growing need to establish a standard for the evaluation of these solutions. Thus, realistic phantom and preclinical environments must be established.

Membranes (Basel)
December 2024
Department of Physical Chemistry, Faculty of Chemistry and Pharmacy, Sofia University St. Kliment Ohridski, 1 "James Bourchier" Blvd., 1164 Sofia, Bulgaria.
Poly(butyl cyanoacrylate) (PBCA) nanoparticles have numerous applications, including drug and gene delivery, molecular imaging, and cancer therapy. To uncover the molecular mechanisms underlying their interactions with cell membranes, we utilized a Langmuir monolayer as a model membrane system. This approach enabled us to investigate the processes of penetration and reorganization of PBCA nanoparticles when deposited in a phospholipid monolayer subphase.

Ophthalmology, Universiti Sains Malaysia, Kota Bharu, MYS.
Gonococcal keratoconjunctivitis (GKC) is an aggressive infection caused by , which can cause an acute, dreadful, ulcerative keratitis resulting in blindness if left untreated. We report a rare case of bilateral GKC complicated with left eye corneal perforation. A 20-year-old male presented with bilateral eye purulent discharge associated with vision loss over the left eye for two weeks prior to presentation.
