1. Holmium laser ablation of the prostate (HoLAP) with moses technology for the surgical treatment of benign prostatic hyperplasia
ABSTRACT Purpose: The expansion of technology is leading to a paradigm shift in several urological fields (1, 2). In particular, the adoption of lasers within the surgical treatment of patients with benign prostatic hyperplasia (BPH) is considered one of the most relevant innovations (3-5). In this video, we aimed to report our experience with holmium laser

7. Mineralogical and gemological characterization of emerald crystals from Paraná deposit, NE Brazil: a study of mineral chemistry, absorption and reflectance spectroscopy and thermal analysis
Abstract The Paraná deposit, located at Southwestern Rio Grande do Norte state, in Brazil, is one of the few emerald deposits found at Borborema Province. The mineralization occurs in phlogopite schists and actinolite-phlogopite schists associated with pegmatites and albitites within the Portalegre Shear Zone. Unlike other well-known Brazilian emerald depos

8. Evidence for varicose vein treatment: an overview of systematic reviews
ABSTRACT BACKGROUND: Varicose veins affect nearly 30% of the world’s population. This condition is a social problem and needs interventions to improve quality of life and reduce risks. Recently, new and less invasive methods for varicose vein treatment have emerged. There is a need to define the best treatment options and to reduce the risks and costs. S

10. Qualitative and Quantitative Chemical Investigation of Orthopedic Alloys by Combining Wet Digestion, Spectroanalytical Methods and Direct Solid Analysis
In this study, two laser-based techniques, laser-induced breakdown spectroscopy (LIBS) and laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) were used for analytical signal evaluation of Ti, Al, and V and investigation of possible harmful elements eventually present as minor elements in Ti alloys. Due to the lack of certified reference

11. Theoretical Approach to Simulate Efficient Selective Solar Absorbers With Micro or Nano Structured Arrays
Study of the solar absorber with photonic crystal or micro structures as the heat absorbing surfaces operated at a high-temperature was conducted. Numerical calculations based on rigorous coupled-wave analysis were performed to determine the absorptance of the photonic crystal surface on the absorber. The effect of nano geometry of the photonic crystal in tu

12. Efficacy of removal of cariogenic bacteria and carious dentin by ablation using different modes of Er:YAG lasers
The primary objective of this in vitro study was to evaluate the efficiency of removal of cariogenic bacteria and carious dentin by ablation using two lasers: fluorescence-feedback controlled (FFC) Er:YAG laser and different pulses of Er:YAG laser based on variable square pulse technology (VSPt). The secondary objective was to measure the temperature during
