There is evidence that the concomitance of psoriasis and obesity may originate from interplay between multiple genetic pathways involve gene–gene interactions. The aim this study was to compare background related among psoriatic patients versus healthy controls by means a Genome-Wide Association Study (GWAS). A total 972 5878 donors were enrolled in study. DNA samples genotyped for over 500,000 single nucleotide polymorphisms (SNPs) using Infinium CoreExome BeadChips (Illumina, San Diego,...

Low-level laser (light) therapy (LLLT) has been applied recently to body contouring. However the mechanism of LLLT-induced reduction subcutaneous adipose tissue thickness not elucidated and proposed hypotheses are highly controversial. Non-obese volunteers were subject 650nm LLLT therapy. Each patient received 6 treatments 2-3 days apart one side abdomen. The contralateral was left untreated served as control. Subjects' abdominal measured by ultrasound imaging at baseline 2 weeks...
