Energy Stress‐Induced Neuroprotection Against Ferroptosis in Dopaminergic Neurons

Journal of Neurochemistry, Volume 170, Issue 6, June 2026.
Energy stress via glucose deprivation activates AMPK and protects dopaminergic neurons from ferroptosis by limiting lipid peroxidation. In contrast, glucose availability supports ferroptosis through oxidizable lipid pools. ABSTRACT Ferroptosis, an iron‐dependent form of regulated necrosis, is implicated in the pathogenesis of Parkinson's disease (PD ...

Biochimie cellulaire

, 1974
La révolution moléculaire en biologie comprend quatre volets : l’identification chimique du matériel héréditaire en tant qu’acide nucléique polymérisé, l’élucidation des structures des macromolécules biologiques, la preuve que la structure et la biosynthèse des protéines – en particulier des enzymes – sont gouvernées par des gènes spécifiques ; plus ...

COQ7‐Related Neuropathy: Two New Cases and Review of the Literature

Journal of the Peripheral Nervous System, Volume 31, Issue 2, June 2026.
ABSTRACT Background and Aims Biallelic variants in COQ7 have been associated with inherited neuropathy. COQ7 encodes a mitochondrial protein directly involved in coenzyme Q10 (CoQ10) biosynthesis. Methods Two unreported and unrelated cases of COQ7‐related neuropathy are presented, along with a review of all previously published cases to highlight the ...

DNA recovery from used malaria RDT to detect Plasmodium species and to assess Plasmodium falciparum genetic diversity: a pilot study in Madagascar

Malaria Journal, 2022
Background Rapid diagnostic tests (RDT) are widely used for malaria diagnosis in Madagascar, where Plasmodium falciparum is the predominant species. Molecular diagnosis is essential for malaria surveillance, but requires additional blood samples for DNA ...

Microbial Controls on Dissolved Organic Nitrogen Cycling During Long‐Term Degradation Experiments

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Dissolved organic nitrogen (DON) is critical for marine microbial growth by providing carbon and nitrogen. Although DON is rapidly cycled, some compounds within this pool can persist for long‐periods of time. To better understand how DON is cycled by marine microorganisms, we conducted 548‐day incubations using surface‐derived dissolved ...

Unlocking the Functionalization and Reactivity of Ethylene Bridges in [2.2]Paracyclophanes: Strategies and Challenges

European Journal of Organic Chemistry, Volume 29, Issue 20, 27 May 2026.
Bridging the gap. Beyond deck functionalization, the ethylene bridges of [2.2]paracyclophanes offer a largely unexploited reactivity landscape. This review showcases strategies to functionalize these bridges and leverage them to build novel cyclophane architectures.

A case report of a mild form of multiple acyl-CoA dehydrogenase deficiency due to compound heterozygous mutations in the ETFA gene

BMC Medical Genomics, 2020
Background Multiple acyl-CoA dehydrogenase deficiency (MADD), previously called glutaric aciduria type II, is a rare congenital metabolic disorder of fatty acids and amino acids oxidation, with recessive autosomal transmission.

Human plasma albumin transports [13C]docosahexaenoic acid in two lipid forms to blood cells

Journal of Lipid Research, 1997
Docosahexaenoic acid (22:6) decreases blood platelet function and is highly concentrated in the brain where its depletion leads to functional impairments.
