Chemiluminescence-promoted oxidation of alkyl enol ethers by NHPI under mild conditions and in the dark.

The hydroperoxidation of alkyl enol ethers using -hydroxyphthalimide and molecular oxygen occurred in the absence of catalyst, initiator, or light. The reaction proceeds through a radical mechanism that is initiated by -hydroxyphthalimide-promoted autoxidation of the enol ether substrate. The resulting dioxetane products decompose in a chemiluminescent reaction that allows for photochemical activation of -hydroxyphthalimide in the absence of other light sources.

FINO initiates ferroptosis through GPX4 inactivation and iron oxidation.

Ferroptosis is a non-apoptotic form of regulated cell death caused by the failure of the glutathione-dependent lipid-peroxide-scavenging network. FINO is an endoperoxide-containing 1,2-dioxolane that can initiate ferroptosis selectively in engineered cancer cells. We investigated the mechanism and structural features necessary for ferroptosis initiation by FINO.

Length of exposure to antiphospholipid antibodies, rather than age, is a risk factor for thrombosis: a retrospective single-centre observational study.

To investigate the association of age and other factors with thrombosis risk in antiphospholipid antibody (aPL) carriers, a retrospective observational study was conducted in a cohort of patients with medium-high aPL titres recruited in a tertiary care hospital. Assuming an age difference of 9.8 years between patients with and without thrombosis, we estimated that a sample size of 70 participants was required.

[Geophagy associated with severe anemia in non-pregnant women: A case series of 12 patients].

Introduction: Geophagy or soil eating is mostly described in pregnant women from Sub-Saharan Africa, South America. Here, we report 12 cases of geophagy associated with severe anemia in non-pregnant Nigerian women.

Results/case Reports: The median age at diagnosis was 34.

[Brown tumor as an exceptional origin of lumbocruralgia with favourable outcome].

Introduction: We report a case of a particular lumbar and radicular pain revealing primary hyperparathyroidism and discuss its characteristics through a literature review.

Case Report: A 55-year-old woman was hospitalized for a nerve root pain associated with recent weight loss with normal physical examination. Biology showed no evidence for acute phase response and normal kidney and liver functions.
