Developmental and Epileptic Encephalopathy due to Biallelic Pathogenic Variants in PIGM
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective PIGM encodes a critical enzyme in the glycosylphosphatidylinositol (GPI)‐anchor biosynthesis pathway. While promoter‐region mutations in PIGM have been associated with a relatively mild phenotype characterized by portal vein thrombosis and absence seizures, recent evidence suggests that coding‐region mutations result in a more severe

Temperature-induced reversal of magnetic interlayer exchange coupling
, 2008 For epitaxial trilayers of the magnetic rare-earth metals Gd and Tb, exchange coupled through a non-magnetic Y spacer layer, element-specific hysteresis loops were recorded by the x-ray magneto-optical Kerr effect at the rare-earth $M_5$ thresholds. This

Effect of Chinese policies on rare earth supply chain resilience
Resources, Conservation and Recycling, 2019 Rare earths elements (REE) are considered as strategic resources because they interact with business and governments’ direct policy interventions. Policy interventions can have a major effect on security of rare earth supply (Kooroshy et al., 2015).

Ketogenic Diet as an Epigenetic Therapy in SETD1B‐Related Epilepsy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Histone lysine methyltransferases such as SETD1B regulate chromatin structure and gene transcription. Ketone bodies, including butyrate, act as histone deacetylase inhibitors. We report a 4‐year‐old boy with SETD1B‐related absence epilepsy, refractory to conventional medications, who achieved sustained > 90% seizure reduction on the Modified ...
