Telomerase discovery using a DNA-PAINT technique.
MB-PDT led to complete inhibition of all isolates at geometric mean concentrations of 1-16 mg/L. Efficacy was independent of incubation time prior to illumination, terbinafine susceptibility (MICs ≤0.004-4 mg/L) and presence of SQLE mutations. Ertugliflozin However, the MB-PDT MIC was slightly elevated (MB 2-8 mg/L and 8-16 mg/L) in isolates from two pigmented cultures of Trichophyton interdigitale (one wildtype and one harbouring L393F) with a darker color when compared to unpigmented cultures (MB 0.5-4 mg/L).

Terbinafine resistant and susceptible strains are equally susceptible to MB-PDT. Lower efficacy was observed against dark coloured isolates which we speculate may be due to melanisation interfering with photo-activation due to preferential light absorption.

Rumenostomy is a useful procedure commonly performed in cattle for medical treatment of domestic ruminants with forestomach diseases. Methylene blue (MB)-mediated antimicrobial photodynamic therapy (APDT) has been broadly investigated to treat infected wounds.

The aim of the study was to evaluate the effectiveness of MB-mediated APDT (MB-APDT) combined with chlorhexidine and zinc oxide ointment on wound healing process after rumenostomy.

Fourteen Nelore bulls were subjected to rumenostomy procedure. Animals were randomly divided into MB-APDT (MB associated with a red diode laser performed immediately after surgery and repeated on days 3, 5, 7 and 10) and control groups. Daily care included topical cleaning with chlorhexidine 2% followed by topical zinc oxide ointment. Animals were followed-up until the 28th day.

Wounds presented a better post-surgical profile in MB-APDT group when it was compared with the control group. In MB-APDT group, it was also possible to observe less pain on palpation of wounds borders, less edema and inflammatory exudate. Additionally, animals from MB-APDT group were faster discharged from the cattle care facility.

Our results support the use of MB-APDT for the post-surgical management of rumenostomy. This pilot study ratifies the use of APDT in cattle and also suggests that it could be performed for other surgical procedures as a complementary approach or an alternative for topical administration of antibiotics.

The aim of this study was to investigate the adhesive bond strength and fracture analysis of resin based restorations to carious dentin of hypomineralized molars (HMs) after disinfecting with photodynamic therapy (PDT), NdYAG and chlorhexidine (CHX).

Sixty carious HM molars were investigated. After removal of all carious infected tissue, the cavities were condition with methylene blue initiated PDT, a 1064 nm wavelength NdYAG laser or 2.0% CHX gel. Non-carious dentin from HM was used as a control without performing any disinfection or conditioning technique. All samples were bonded using a one-step one-coat adhesive bond over the dentin surface, packed with composite and light cured. All specimens were subjected to thermocycling at 5°C and 60°C with a dwell time of 30 s for 10,000 cycles. Bonded specimens were placed on a universal testing machine with a flat loading head. The debonded surface were viewed under light optical microscope to estimate the type of failure including adhesive, cohesive, and admie compared to other laser treatment strategies.
Caries infected hypomineralized teeth demonstrated lower bond strength values compared to non-carious hypomineralized teeth. Adhesive bond strength of hypomineralized teeth was highest with chlorhexidine compared to other laser treatment strategies.
The photokilling rate in antimicrobial photodynamic therapy (a-PDT) is highly related to interaction of reactive oxygen species (ROS) produced, ability of photosensitizers (PS) in incorporating into microorgansims and light devices/microorganism type. Since xanthene dyes (Rose Bengal and Erythrosine) are present in the dental practice as PS, have high quantum yield of singlet oxygen and are efficiently incorporated into bacterial cells, the additive bactericidal ability of a combination of xanthene dyes was tested on planktonic cultures and biofilms of Streptococcus mutans when irradiated by a hand-held LED photopolymerizer unit.

Planktonic cultures of S. mutans (UA 159 ATCC 700610) were grown in BHI broth with 1 % sucrose. This culture was exposed to a concentrations of Rose Bengal (RB) and Erythrosine (ER) at 1.5, 3.5 μM, in combination (RB + ER + L+) / alone (RB + L+/ ER + L+) and irradiated with a blue LED high light intensity (L). Accordingly, concentrations of dyes and time irradiation were increased in 10 times and applied on 120 h - biofilms of S. mutans and compared with a 0.12 % Chlorhexidine solution (0.12 % - CHX). For statistical analysis, parametrical procedures were applied (n = 6; ANOVA test and Tukey post hoc test; α = 0.05) and data transformed into log
.

Substantial antimicrobial reduction was verified in planktonic cultures (∼ 7 log reduction) and biofilm (∼ 1 log reduction) for combined a-PDT group (RB + ER + L+) presenting a significant statistical difference to control group (p < 0.05) with similar effect to CHX group (p > 0.05).

Different forms of S. mutans can be effectively controlled by photodynamic therapy and optimized when in combination of xanthene dyes.

Precision or personalized Medicine (PM) is used for the prevention and treatment of diseases by considering a huge amount of information about individuals variables. Due to high volume of information, AI-based computational models are required. A large set of studies conducted to examine the PM approach to improve childhood clinical outcomes. Thus, the main goal of this study was to review the application of health information technology and especially artificial intelligence (AI) methods for the treatment of childhood disease using PM.

PubMed, Scopus, Web of Science, and EMBASE databases were searched up to December 18, 2019. Articles that focused on informatics applications for childhood disease PM included in this study. Included papers were classified for qualitative analysis and interpreting results. The results were analyzed using Microsoft Excel 2019.

From 341 citations, 62 papers met our inclusion criteria. The number of published papers that used AI methods to apply for PM in childhood diseases increased from 2010 to 2019.
