Retinal microvascular and microstructural alterations in the diagnosis of dermatomyositis: a new approach.

Purpose: To study the relationship between fundus alterations, including retinal thickness and microvascular changes, and dermatomyositis (DM) using optical coherence tomography angiography (OCTA).

Methods: A total of 16 patients with DM (32 eyes) and 16 healthy controls (HCs; 32 eyes) participated in this study. Based on the Early Treatment Diabetic Retinopathy Study subzones, OCTA fundus data were divided into different layers and regions for comparison.

Degradation pathways and kinetics of anthraquinone compounds along with nitrate removal by a newly isolated Rhodococcus pyridinivorans GF3 under aerobic conditions.

A novel Rhodococcus pyridinivorans GF3 capable of degrading anthraquinone compounds (ACs) was isolated from 1-amino-4-bromoanthraquinone-2-sulfonic acid contaminated soil under aerobic conditions. Strain GF3 could degrade nine ACs at 150 rpm and 30 °C. LC-MS analysis showed that ACs were degraded via catechol and salicylic acid-produced pathways, which were different from previously reported phthalic acid-produced pathway.
