Design and Characterization of Non-Erosive Polymeric Tooth-Whitening Compositions

Applied Sciences, 2023
We investigated the physical properties and tooth-whitening effect of polymeric tooth-whitening compositions based on orally acceptable polymers, polyvinyl acetate (PVAc), ethyl cellulose (EC), and polyvinyl pyrrolidone.

Spontaneous detachment of Streptococcus mutans biofilm by synergistic effect between zwitterion and sugar alcohol

Scientific Reports, 2017
A biofilm, a community of microorganisms, is highly resistant to antibiotics, resulting in massive losses in various areas. We herein present a strategy to remove Streptococcus mutans biofilms through a spontaneous exfoliation by the synergistic effect ...

Anti-Hair Loss Effect of Adenosine Is Exerted by cAMP Mediated Wnt/β-Catenin Pathway Stimulation via Modulation of Gsk3β Activity in Cultured Human Dermal Papilla Cells

Molecules, 2022
In the present study, we investigated the molecular mechanisms of adenosine for its hair growth promoting effect. Adenosine stimulated the Wnt/β-catenin pathway by modulating the activity of Gsk3β in cultured human dermal papilla cells. It also activated

Analysis of biofilm and bacterial communities in the towel environment with daily use

Scientific Reports, 2023
Towels differ remarkably from other textile products in their fibre structure and usage, and microbial behaviours on towels remain underexplored. Thus, we evaluated biofilm formation on towels during use for 6 months in daily life and analysed its ...

Hair Pores Caused by Surfactants via the Cell Membrane Complex and a Prevention Strategy through the Use of Cuticle Sealing

Cosmetics, 2023
In this study, we discovered that washing hair with surfactants causes a decrease in the internal density of hair, and we propose a cuticle-sealing strategy to inhibit this phenomenon.

Eco-Friendly Silica Microcapsules with Improved Fragrance Retention

Applied Sciences, 2022
Microcapsules are employed extensively in various applications; however, most are composed of synthetic plastics. Thus, substitution of their component materials is essential to prevent environmental problems associated with primary microplastics. Herein,

Generalized Householder Transformations

Entropy, 2021
The Householder transformation, allowing a rewrite of probabilities into expectations of dichotomic observables, is generalized in terms of its spectral decomposition. The dichotomy is modulated by allowing more than one negative eigenvalue or by abandoning binaries altogether, yielding generalized operator-valued arguments for contextuality.

Stressful Events Reported by Childhood Cancer Survivors and Community Controls From the St. Jude Lifetime (SJLIFE) Cohort: A Mixed Method Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Characterizing stressful events reported by childhood cancer survivors experienced throughout the lifespan may help improve trauma‐informed care relevant to the survivor experience. Methods Participants included 2552 survivors (54% female; 34 years of age) and 469 community controls (62% female; 33 years of age) from the St.
