Background And Objective: Recently, the first diode laser with a wavelength of 755 nm for in-motion hair removal came on the market. The objective of this study was to check its efficacy, safety, and practicality under different options for its use.
Methods: A prospective study in a heterogeneous group of 56 patients who had hair removed from various areas of their bodies using three different treatment methods. Four sessions were scheduled in all cases, with a gap of 3 months between each session. Efficacy was assessed by counting of hairs per cm and the adverse effects in each session were recorded in detail in the patients' clinical histories.
Results: The three tested options achieved a significant reduction in the number of hairs (P < 0.0001). The average clearances achieved using the conventional method (HR), the in-motion method (SHR) and the stacking method were 75.5%, 70.1%, and 41.9%, respectively. The degree of satisfaction of the participants on a scale of 0-10 was 7.7, 8.1 and 6.8, respectively. Erythema and perifollicular edema, which are characteristic responses in laser hair removal, were observed. The incidence of burns was 1.33%.
Conclusion: The 755-nm diode laser performed efficiently and safely in all the tested areas, using high total accumulated energy per surface unit. Based on our prior experience with other equipment, the results are promising. Lasers Surg. Med. 49:355-360, 2017. © 2016 Wiley Periodicals, Inc.

Enhancing signal-to-noise ratio in real-time LED-based photoacoustic imaging: A comparative study of CNN-based deep learning architectures.

Recent advances in Light Emitting Diode (LED) technology have enabled a more affordable high frame rate photoacoustic imaging (PA) alternative to traditional laser-based PA systems that are costly and have slow pulse repetition rate. However, a major disadvantage with LEDs is the low energy outputs that do not produce high signal-to-noise ratio (SNR) PA images. There have been recent advancements in integrating deep learning methodologies aimed to address the challenge of improving SNR in LED-PA images, yet comprehensive evaluations across varied datasets and architectures are lacking.

Methods: Fourty-five individuals with post-surgical or post-traumatic scars were randomly divided into three groups: Group A received four fractional Er:YAG laser sessions spaced four weeks apart along with eight sessions of intradermal PRP injections spaced two weeks apart; Group B received four fractional Er:YAG laser sessions spaced four weeks apart along with two sessions of light emitting diode (LED) weekly; and Group C received four fractional Er:YAG laser sessions spaced four weeks apart. Treatment efficacy was evaluated using clinical photographs, Vancouver Scar Scale (VSS), patient satisfaction and histopathology.

The inherent potential for self-assembly is a well-known attribute of organic dye molecules. This work takes advantage of the changes in dye photochemical and photophysical properties produced by the aggregation phenomenon, to investigate the behavior of all-optical modulation in molecular aggregates. The theoretical principles for a dual beam all-optical modulation, as well as the conception of an optical logic gate by exploring the aggregation phenomenon are discussed throughout the article.

Objective: This study compares the color change of non-vital anterior teeth after laser-activated bleaching and conventional walking bleaching technique.
Materials And Methods: Sixty extracted teeth were endodontically treated, stained in a black tea solution, and the baseline shade was measured using a spectrophotometer (Easyshade, VITA). Bleaching was done using either: internal bleaching with 35% HO (Opalescence Endo) and then tooth sealed for 5 days (Gr1), 35% HO (JW Next) for 7 minutes (Gr2), internal and external bleaching for 7 minutes (Gr3), diode laser-activated internal bleaching for 30 seconds (940 nm, continuous wave, 2 W, noncontact mode, 300 um, non-initiated tip), wait for 7 minutes, second laser application for 30 seconds, tooth sealed for 5 days (Gr4), diode laser-activated internal bleaching for 24 hours (Gr5), or diode laser-activated internal and external bleaching for 24 hours (Gr6) ( = 10).
