Sudan red dye

, 2020
Sudan red or 1-[(2-methoxyphenyl)azo]-2-naphthol is a low molecular weight azoic agent widely used in industry, particularly in the production of hair dyes. The use of this product in the food industry is prohibited due to its potential carcinogenic effect, but no respiratory involvement has been reported to date.

Morphological and Molecular Characterization of Eimeria saudiensis From Arabian Oryx (Oryx leucoryx) Held in Captivity in the Sultanate of Oman 阿曼苏丹国圈养阿拉伯羚羊 (Oryx leucoryx) 体内沙特艾美球虫 (Eimeria saudiensis) 的形态学与分子特征

Wildlife Letters, EarlyView.
Eimeria saudiensis represents a genus of apicomplexan parasites capable of inducing coccidiosis in Arabian oryx. Our research concentrated on the morphological and molecular investigation of Eimeria spp. in the captive oryx herd in Oman. The therapeutic and management practices employed at the Mammals Breeding Center were reassessed to diminish ...

Lipofuscin: The Missing Link in the Worsening of Obstructive Sleep Apnea

The Laryngoscope, Volume 136, Issue 5, Page 2362-2369, May 2026.
Lipofuscin, also known as the age pigment, is a permanent autofluorescent intracellular deposit that accumulates with aging or oxidative stress, thereby interfering with cellular function. This study revealed significantly larger deposits of lipofuscin in the lateral pharyngeal wall muscles of patients with severe obstructive sleep apnea (OSA) compared
