Histological and electron microscopic analysis of fractional micro-plasma radio-frequency technology effects.

Objective: The aim of this explorative study was to investigate the histological effects of a novel micro-plasma radio-frequency technology for skin rejuvenation the assessment of different parameters.

Methods: Thirty guinea pigs were randomly selected and were distributed into three treatment groups: 40W/10KJ, 60W/10KJ, and 80W/10KJ. The treated skin was analyzed immediately, one week and one month post-treatment using histology and transmission electron microscope (TEM).

[Association of single nucleotide polymorphism in TGFBR2 gene with Kawasaki disease and coronary artery lesions].

Objective: To examine the single nucleotide polymorphism (SNP) (rs1495592) in transforming growth factor-beta receptor 2 (TGFBR2) gene in children, and to investigate its association with Kawasaki disease (KD) and coronary artery lesions (CALs).

Methods: Thirty-five KD patients, 14 of whom had CALs (CAL subgroup), were selected as the case group, and 25 healthy age-matched children were selected as the control group. The SNP (rs1495592) in TGFBR2 gene was studied by gene sequencing.
