Biofilm Removal from In Vitro Narrow Geometries Using Single and Dual Pulse Er:YAG Laser Photoacoustic Irrigation.

The disinfection and removal of biofilm from titanium dental implants remains a great challenge in oral medicine. Here we present results of novel photoacoustic irrigation laser modalities for biofilm removal in model geometries mimicking the peri-implant pocket. The efficacy of single pulse (Er:YAG-SSP) and dual pulse (Er:YAG-AutoSWEEPS) photoacoustic irrigation modalities were determined for biofilm decontamination from titanium surfaces in narrow cylindrical and square gap geometries.

The mitochondrial genome of Sars, 1885 (Crustacea: Branchiopoda: Cladocera) from Hainan Island, China.

is the only Cladoceran in tropical freshwaters and parapatrically occurs with in the transition between the tropics and subtropics. Here, we present the complete mitochondrial genome (MG) determined by next-generation sequencing and offer a phylogenetic analysis of . The MG of is 17,615 bp in size, including 13 protein-coding genes (PCGs), 2 ribosomal RNA, 23 tRNA, and 2 putative control regions.

The effect of post-extraction socket preservation laser treatment on bone density 4 months after extraction: Randomized controlled trial.

Background: Post-extraction bone resorption may affect the outcome of ensuing restorations.

Purpose: This study aimed to evaluate a comprehensive laser post-extraction protocol by comparing resulting alveolar bone regeneration with that obtained after standard extraction procedure.

Materials And Methods: About 53 simple extractions were randomized to either laser or control group.

Photoacoustic removal of Enterococcus faecalis biofilms from titanium surface with an Er:YAG laser using super short pulses.

Biofilms that grow on implant surfaces pose a great risk and challenge for the dental implant survival. In this work, we have applied Er:YAG photoacoustic irrigation using super short pulses (Er:YAG-SSP) to remove biofilms from the titanium surfaces in the non-contact mode. Mature Enterococcus faecalis biofilms were treated with saline solution, chlorhexidine, and hydrogen peroxide, or photoacoustically with Er:YAG-SSP for 10 or 60 s.

Full-face skin resurfacing using a combination of fractional and full spot ablative 2940 nm erbium laser.

Background: Full-field deep ablative laser resurfacing is a popular method for skin rejuvenation due to maximum improvement in a single treatment. However, it is associated with disadvantages such as pain, prolonged erythema, swelling, crusting, infections, pigmentary changes, and scarring. Patients are increasingly seeking less invasive options with comparable effect.

Non-ablative Er:YAG laser therapy effect on stress urinary incontinence related to quality of life and sexual function: A randomized controlled trial.

Objective: Stress urinary incontinence (SUI) is a common complaint in women after childbirth. It affects their quality of life and sexual satisfaction and is one of the major reasons for gynaecological surgery. There is a need for effective non-invasive treatment alternatives.

The thermal tolerance of crayfish could be estimated from respiratory electron transport system activity.

Whether electron transport system (ETS) activity could be used as an estimator of crayfish thermal tolerance has been investigated experimentally. Food consumption rate, respiration rates in the air and water, the difference between energy consumption and respiration costs at a given temperature ('potential growth scope', PGS), and ETS activity of Orconectes limosus and Pacifastacus leniusculus were determined over a temperature range of 5-30°C. All concerned parameters were found to be temperature dependent.
