Central serous chorioretinopathy was treated by laser photocoagulation of the site of fluorescein dye leakage. In 22 cases, in most of which the leakage was located in the nasal macular area or close to the foveola, krypton red was used, and in 85 cases argon blue-green. There was a significantly greater improvement after treatment with the krypton laser, and healing also tended to be faster than with the argon laser.

Blue phase liquid crystal (BPLC) lasers exhibit exceptional optical quality and tunability to external stimuli, holding significant promise for innovative developments in the field of flexible optoelectronics. However, there remain challenges for BPLC elastomer (BPLCE) lasers in maintaining good optical stability during stretching and varying temperature conditions. In this work, a stretchable laser is developed based on a well-designed BPLCE with a combination of partially and fully crosslinked networks, which can output a single-peak laser under small deformation (44.

Importance: Adult laryngeal hemangiomas are rare and may cause symptoms such as dysphonia, dysphagia, and dyspnea. Carbon dioxide (CO2) lasers offer an alternative approach to managing this rare condition.
Objective: The objective of this study is to evaluate the effectiveness of CO2 lasers in treating adult hemangioma and to identify potential side effects associated with this treatment modality.
The efficacy of fractional CO laser with or without triamcinolone acetonide or 5-fluorouracil in the treatment of early postburn hypertrophic scars.

Hypertrophic scars (HTSs) are the result of an abnormal healing process resulting from burns and other severe traumas. The symptoms of that condition include skin irritation, discomfort, and itching. This study aimed to assess the efficacy of fractional carbon dioxide (CO) laser therapy alone or with triamcinolone or 5-fluorouracil (FU) in the treatment of early post-burn hypertrophic scars (HTSs) that develop during the first 6 months after the injury.

Annually, the oil and gas industry faces equipment losses and product quality degradation due to the presence of sulfate-reducing bacteria (SRB). Given the negative impact of SRB, this study evaluates the use of photoinactivation (PI) with zinc chloride double salt of 1,9-Dimethyl-Methylene Blue (DMMB) as a photosensitizer (PS) in varying concentrations and combined with Laser light at different exposures in an SRB consortium. For culture growth, a modified Postgate C medium (without ferrous sulfate) was used, and cell quantification was performed on 100 μL aliquots of the consortium, read on a spectrophotometer (λ600 nm) in an oxygen- and light-free environment at room temperature.

The hydroxysilylene (HSiOH) molecule has been spectroscopically identified in the gas phase for the first time. This highly reactive species was produced in a twin electric discharge jet using separate precursor streams of 16O2/18O2 and Si2H6/Si2D6, both diluted in high pressure argon. The strongest and most stable laser induced fluorescence (LIF) signals were obtained by applying an electric discharge to each of the precursor streams and then merging the discharge products just prior to expansion into vacuum.
