Background And Objectives: The purposes of this study were to demonstrate that laser soldering is safe and effective for tissue bonding in dural reconstruction and to compare this new reconstruction technique to an established one.
Study Design: A temperature-controlled fiberoptic CO(2) laser system or fibrin glue were used for in vitro dural defect reconstruction in two groups of pigs. The CO(2) laser technique was also used for dural reconstruction in live pigs.
Results: The burst pressure of the reconstructed dura by the laser system was significantly higher than that of fibrin glue (mean pressure 258.5 +/- 117.3 cm H(2)O and 76.8 +/- 47.2 cm H(2)O, respectively). There were no postoperative complications and no signs of thermal damage to the dura, fascia, or underlying tissue on histological analysis following the in vivo CO(2) laser experiments.
Conclusions: Temperature-controlled laser soldering is an effective technique for dural repair. It creates a strong tissue bonding with no thermal damage to the tissue. The burst pressure of the reconstructed dura done with laser soldering is significantly higher than that of fibrin glue.

Synthetic antioxidants are often introduced to biodiesel to increase its oxidative stability, and -butyl hydroquinone (TBHQ) has been selected due to its high efficiency for this purpose. The monitoring of antioxidants in biodiesel therefore provides information on the oxidative stability of biodiesels. Herein, a laser-induced graphene (LIG) electrode is introduced as a new sensor for detecting -butyl hydroquinone (TBHQ) in biodiesel samples.

While nanozymes are commonly employed in nanocatalytic therapy (NCT), the efficacy of NCT is hampered by the limited catalytic activity of nanozymes and the intricate tumor microenvironment (TME). In this work, we design a high-efficiency nanozyme with NIR-II photothermal property for the mild hyperthermia-augmented NCT. In order to endow a single-component nanomaterial the ability to simultaneously catalyze and exhibit NIR-II photothermal properties, a straightforward template method is utilized to fabricate sulfur vacancies (V)-doped CoS nanocages.

Background: Neuroendocrine tumors are rare malignancies of the head and neck, especially in the larynx. Variations in the location and morphology of laryngeal neuroendocrine tumors result in a lack of standardized clinical treatment.
Objective: This study aimed to examine the treatment and prognosis of laryngeal neuroendocrine tumors in the G2 stage.

Objective: To evaluate the efficacy of photodynamic therapy (PDT) for vaginal intraepithelial neoplasia grade 1 (VaIN1) related to high-risk (Hr)-human papillomavirus (HPV).
Methods: Participants aged 25-65 years treated for VaIN1 between March 2022 and September 2022 were retrospectively analyzed into three groups. The PDT and follow-up groups were matched 1:1 for gravidity, HPV type, and quadrants involved.

Morphea is a chronic inflammatory fibrosing disorder. Since fibrosis is the hallmark of both scars and morphea, our attention was raised for the possible use of Fractional Ablative CO lasers and microneedling as treatment modalities for morphea. To compare the efficacy and safety of Fractional Ablative CO lasers and microneedling in the treatment of morphea.
