Gingival inflammation and plaque accumulation affect therapeutic outcomes in patients with acne vulgaris

Journal of Periodontology, EarlyView.
Abstract Background We hypothesized that acne vulgaris (AV) and gingivitis were associated through systemic inflammatory mechanisms, sharing common etiological factors. This study aimed to identify the association between AV and gingivitis and to assess changes in acne severity in relation to changes in the plaque index (PI).

Efficacy and Safety of Small‐Spot 755 nm Picosecond Laser‐Induced Optical Breakdown for Novel Photomechanical Skin Ablation in Asian Patients

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objectives Conventional ablative and photothermal lasers are commonly used to treat superficial pigmentary lesions but often induce thermal injury and post‐inflammatory hyperpigmentation (PIH), particularly in Asian skin. Picosecond 755‐nm alexandrite lasers with diffractive lens arrays (DLA) create laser‐induced optical breakdown (LIOB ...

Composition Analysis of Sebum Lipids by ATR-FTIR Spectroscopy.

Journal of Society of Cosmetic Chemists of Japan, 1997
著者らは簡便性, 迅速性と成分定量性を併せ持つ皮脂分析法としてAL-ATR法の開発を検討した。本法は, アルミホイルで皮脂を採取し, ATR-FTIR法による測定で得られたスペクトルをPLS法を応用したプログラムで解析することにより, 皮脂の主要成分であるトリグリセライド, 遊離脂肪酸, スクアレン, ワックスエステルを定量する方法である。この方法の妥当性を検討したところ, 以下の結果が得られた。 (1) ATR-FTIR法の検量線は直線性を示し, 再現性も良好であった。 (2) 本法での定量値をGC法と比較したところ有意な相関が認められた。 (3) 皮脂採取方法としてアルミホイルと濾紙を比較したところ, 採取される成分の組成はほぼ同等であった。本法は皮脂採取から定量まで約5分と短時間であり ...
