From model validation to biomechanical analysis: In silico study of multirooted root analogue implants using 3D finite element analysis.

Objectives: To create a validated 3D finite element model and employ it to examine the biomechanical behaviour of multirooted root analogue implants (RAIs).

Methods: A validated finite element model comprising either an RAI or a threaded implant (TI) and an idealised bone block was developed based on a previously conducted in vitro study. All the experimental boundary conditions and material properties were reproduced.

Cobalt oxide nanoparticles induce cytotoxicity and excessive ROS mediated mitochondrial dysfunction and p53-independent apoptosis in melanoma cells.

Nanotherapy has emerged as a promising strategy for the targeted and efficient treatment of melanoma, the most aggressive and lethal form of skin cancer, with minimized systemic toxicity. However, the therapeutic efficacy of cobalt oxide nanoparticles (CoONPs) in melanoma treatment remains unexplored. This study aimed to assess the therapeutic potential of CoONPs in melanoma treatment by evaluating their impact on cell viability, genomic DNA and mitochondrial integrity, reactive oxygen species (ROS) generation and apoptosis induction in melanoma A-375 cells.

The Use of Knives With Versus Without Integrated Water-jet Function During Peroral Endoscopic Myotomy for Patients With Achalasia: A Meta-analysis.

Background: Peroral endoscopic myotomy (POEM) is a well-established endoscopic treatment for achalasia, utilizing an endoscopic knife for dissection. Recently, new knives with an integrated water-jet (WJ) function have been introduced. This study aims to compare the technical, perioperative, and late postoperative outcomes between WJ knives and conventional (C) knives, which lack the WJ function, through a pairwise meta-analysis of published comparative studies.

Posterior Peroral Endoscopic Myotomy With Versus Without Sparing of the Oblique/Sling Fibers: A Meta-analysis.

Background And Aims: Several studies have hypothesized that sparing the oblique/sling fibers during posterior peroral endoscopic myotomy (POEM) may reduce the incidence of gastroesophageal reflux disease (GERD) and reflux esophagitis without compromising the established safety and efficacy of the procedure. This study compares perioperative, postoperative motility-related, and postoperative GERD-related outcomes between posterior oblique/sling fibers-sparing POEM (OFS-POEM) and conventional posterior POEM through a pairwise meta-analysis of comparative studies.

Methods: We conducted a systematic literature review following PRISMA guidelines to identify articles directly comparing posterior OFS-POEM with conventional posterior POEM.
