Assessing the swelling behavior of oil paint in fatty acid methyl esters (FAMEs).

Fatty Acid Methyl Esters (FAMEs) have gained attention as low-impact solvents, offering low toxicity and versatility in applications ranging from biofuels to chemical feedstocks. This study investigates the swelling behavior of naturally-aged zinc white oil paint fragments when exposed to FAMEs with varying chain lengths. Swelling was monitored using a microscopy-based image analysis technique over a 15 minutes period, demonstrating that FAMEs induce low to moderate swelling in oil paints, consistent with prior findings on solvent-paint interactions.

Omalizumab Drug Survival in Chronic Urticaria: A Retrospective Multicentric French Study.

Background: Omalizumab (OMA) dramatically improves disease control and quality of life in patients with chronic urticaria (CU).

Objective: We aimed to evaluate the discontinuation patterns of OMA and their determinants in a cohort of French patients with CU.

Methods: We conducted a retrospective multicenter study in 9 French tertiary referral hospitals.
