Tailor-made blanks are sheet metal assemblies with different thicknesses and/or materials and/or surface coatings. A monolithic sheet can be machined to make the required thickness variations that is referred as tailor machined blanks. Due to the thickness variation in tailor machined blanks, laser bending of these blanks is more complicated than monolithic plates. In this article, laser formin...

the minimal invasive nature of lasers, with quick tissue response and healing has made them a very attractive technology in various fields of dentistry which serves as a tool to create a better result than ever before. the rapid development of lasers and their wavelengths with variety of applications on soft and hard tissues may continue to have major impact on the scope and practice in prosthe...

Lipid keratopathy is a disease in which fat accumulates and feeding vessels penetrate the cornea. When fat accumulates at the center, visual acuity decreases. To date, no useful treatments have been confirmed, but favorable results appear to be obtained using photodynamic therapy. In photodynamic therapy for cancer, cells are selectively killed by intravenous injection of a light-sensitive subs...

Combination of photothermal and photodynamic therapy (PTT/PDT) offer unique advantages over PDT alone. However, to achieve synergetic PDT/PTT effect, one generally needs two lasers with different wavelengths. Near-infrared dye IR-780 could be used as photosensitizer both for PTT and PDT, but its lipophilicity limits its practical use and in vivo efficiency. Herein, a simple multifunctional IR78...

Hydroxylapatite (HA) nanoparticles were conjugated with quantum dots (QDs) for in vivo imaging. The surface structures of HA nanoparticles with conjugated quantum dots (HA-QD) were studied by transmission electron microscopy (TEM) and laser fluorescent spectroscopy. The TEM data showed that the quantum dots were well conjugated on the HA nanoparticle surfaces. The laser fluorescent spectroscopy...

Laser endoscopic surgery, especially the effectiveness of photodynamic therapy (PDT) using Photofrin as a photosensitizer, has now achieved a status as effective treatment modality for lung cancer. Twenty-six lung cancer patients received the preoperative PDT for the purpose of either reducing the extent of resection or increasing operability. Bronchoscopical PDT is performed with topical anest...

PURPOSE Intraoperative optical biopsy technologies may aid in the identification of important anatomical landmarks and improve surgical outcomes of robotic assisted radical prostatectomy. We evaluate the feasibility of confocal laser endomicroscopy during robotic assisted radical prostatectomy. MATERIALS AND METHODS A total of 21 patients with biopsy proven prostate cancer scheduled for robot...

Background: Low-level lasers are used for various medical applications including wound healing and hair loss treatment. Cell Therapy using skin stem cells could be a novel approach to hair transplantation. However, there is no study on the effect of low-level laser on the hair follicle stem cells. So, in this study, we investigated the effect of low level laser irradiation on viability and ROS ...
