New-onset refractory status epilepticus after SARS-CoV-2 infection: a review of literature.

Athanasios, Nafpliou 1 C, Gerakas 15344, Athens, Greece,
Although severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) primarily affects the respiratory system, neurological symptoms were reported both during acute and post-acute COVID-19. Notably, patients with no history of epilepsy or other neurological conditions developed new-onset refractory status epilepticus (NORSE) weeks, months, or even up to a year following the viral infection. While NORSE is uncommon, it carries a high mortality rate and can result in permanent epilepsy.

Quantitative Proteomics Identifies Profilin-1 as a Pseudouridine-Binding Protein.

Pseudouridine (Ψ) is the most abundant RNA modification in nature; however, not much is known about the biological functions of this modified nucleoside. Employing an unbiased quantitative proteomics method, we identified multiple candidate reader proteins of Ψ in RNA, including a cytoskeletal protein profilin-1 (PFN1). We demonstrated that PFN1 binds directly and selectively to Ψ-containing RNA.

The enantioselective synthesis of 1,4-dicarbonyl compounds continues to pose a significant challenge in organic synthesis, and a catalytic process which generates two adjacent stereogenic centers with full stereochemical control is lacking until now. The 1,4-relationship of the functional groups requires an Umpolung strategy as one of the α-carbonyl positions has to be inverted into an electrophilic center to react with a normal enolate. We report herein the highly enantio- and diastereoselective addition of silyl ketene acetals toward electrophilic 1-azaallyl cations to furnish chiral 4-hydrazonoesters, which are masked 1,4-dicarbonyl compounds.

Direct translocation of RNA with secondary structures using single-molecule electrophoresis through protein nanopores shows significant fluctuations in the measured ionic current, in contrast to unstructured single-stranded RNA or DNA. We developed a multiscale model combining the oxRNA model for RNA with the 3-dimensional Poisson-Nernst-Planck formalism for electric fields within protein pores, aiming to map RNA conformations to ionic currents as RNA translocates through three protein nanopores: α-hemolysin, CsgG, and MspA. Our findings reveal three distinct stages of translocation (pseudoknot, melting, and molten globule) based on contact maps and current values.
