The isomerization of dimethyl 2,3-dibromofumarate in chloroform solutions was investigated by the combination of nuclear magnetic resonance (NMR) and density functional theory (DFT) calculations. The bromination of dimethyl acetylenedicarboxylate leading to dimethyl 2,3-dibromofumarate produces the isomer initially, which however converts into the more stable isomer. The conversion from to is spontaneous and greatly accelerated by light.

Background: Paraquat (PQ) is a widely used pesticide, can cause severe intoxication and respiratory failure. Myrtenol (Mrl), an essential oil derived in various plants, exhibits several biological properties, including anti-inflammatory and antioxidant activities. This study aims to investigate the protective potential of Mrl against oxidative stress and inflammation caused by PQ exposure.

Macrophages exhibit diverse phenotypes depending on environment status, which contribute to physiological and pathological processes of immunological diseases, including sepsis, asthma, multiple sclerosis and colitis. The alternative activation of macrophages is tightly regulated to avoid excessive activation and damage of tissues and organs. Certain works characterized that succinate dehydrogenase (SDH) altered function of macrophages and promoted inflammatory response in M1 macrophages via mitochondrial reactive oxygen species (ROS).

Rechargeable zinc batteries (RZBs) are hindered by two primary challenges: instability of Zn anode and deterioration of the cathode structure in traditional aqueous electrolytes, largely attributable to the decomposition of active H2O. Here, we design and synthesize a non-flammable water-in-dimethyl sulfoxide electrolyte to address these issues. X-ray absorption spectroscopy, in situ techniques and computational simulations demonstrate that the activity of H2O in this electrolyte is extremely compressed, which not only suppresses the side reactions and increases the reversibility of Zn anode, but also diminishes the cathode dissolution and proton intercalation.

Objective: This study aimed to review the efficacy and safety profile of disease-modifying therapies (DMTs) in patients with relapsing pediatric-onset multiple sclerosis (POMS).
Methods: A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Published randomized controlled trials (RCTs), nonrandomized studies with a control group, large single-arm studies, and ongoing (unpublished) studies investigating the use of approved and unapproved DMTs in POMS were included.
