Aims: The aim of the current study was to examine the effects of diode laser (970 nm) when used as adjunct to mechanical debridement on reattachment of fibroblast cell cultures to the root surface.
Materials And Methods: Eighteen extracted single-rooted human teeth were used in the study. Briefly, the anatomical crowns were removed; roots were sectioned and preserved in antiseptic solution. The sections were divided into three groups: (i) scaling and root planing (SRP), (ii) SRP followed by diode laser exposure and (iii) untreated control group. All the sections were inoculated with NIH 3T3 mouse fibroblast cell lines and cell attachment was confirmed by scanning electron microscopy analysis and growth was quantitatively assessed by MTT assay after days 1, 3 and 5.
Results: On intragroup analysis, there was significant cell proliferation seen on day 1 and day 5. However, no significant differences were observed between the treatment groups at the various time points.
Conclusion: 970-nm diode laser exposure had a positive effect in enhancing the fibroblast reattachment to root surfaces. However, to ascertain the role of laser treatment in enhancing the rapid cell growth compared to SRP, further quantitative studies with more sample numbers are required.

Purpose: To evaluate an alternative surgical approach for Port Delivery System with ranibizumab (PDS) implant and a novel application of Iridex laser system in Gottingen minipig model.
Methods: A total of seventeen male minipigs (Part 1: 9 animals in non-recovery and Part 2: 8 animals observed for 8-days post-surgery Part 2) received PDS implant insertion into each eye. The effect of Iridex 810 nm infrared diode laser with varying energy (power or duration) on transscleral pars plana ablation, surrounding ocular tissue and postsurgical vitreous hemorrhage (VH) was investigated.
Efficacy and safety of office-based diode laser ablation for recurrent low-grade non-muscle-invasive bladder cancer under local anaesthesia: A pilot study.

Introduction: Low-grade tumors account for approximately 50% of non-muscle invasive bladder cancer (NMIBC) with recurrence rates between 46% and 62%. Management of NMIBC recurrence typically involves transurethral resection of bladder tumor (TURBT) under general or regional anesthesia, which carries perioperative risks and considerable healthcare costs due to repeated procedures. Therefore, less invasive treatments such as office-based laser ablation, which aim to manage recurrences and reduce inpatient procedures without compromising oncological control, are needed.

Introduction And Objectives: Laser vaporization techniques have emerged as a prominent alternative to transurethral prostate resection in managing benign prostatic obstruction (BPO). This study focuses on assessing the effectiveness of the ejaculatory preserving laser vaporization of the prostate technique compared to the conventional non-ejaculatory approach in managing BPO.
Patients And Methods: Our study was performed between August 2022 and September 2023.

Laser diodes based on solution-processed semiconductor quantum dots (QDs) present an economical and color-tunable alternative to traditional epitaxial lasers. However, their efficiency is significantly limited by non-radiative Auger recombination, a process that increases lasing thresholds and diminishes device longevity through excessive heat generation. Recent advancements indicate that these limitations can be mitigated by employing spherical quantum wells, or quantum shells (QSs), in place of conventional QDs.

Common-signal-induced synchronization of semiconductor lasers have promising applications in physical-layer secure transmission with high speed and compatibility with the current fiber communication. Here, we propose an ultra-long-distance laser synchronization scheme by utilizing random digital optical communication signal as the common drive signal. By utilizing the long-haul optical coherent communication techniques, high-fidelity fiber transmission of the digital drive can be achieved and thus ultra-long-distance synchronization is expected.
