Narcolepsy in early childhood: a case report and a Mini review.

Narcolepsy is a sleep-wake disorder with an onset commonly seen in individuals aged 10-30 years. Due to various reasons, the diagnosis of narcolepsy often experiences a delay of at least ten years. Diagnosing narcolepsy in children is particularly challenging due to atypical symptoms, leading to frequent misdiagnosis or missed diagnoses.

Co-Amorphization, Dissolution, and Stability of Quench-Cooled Drug-Drug Coamorphous Supersaturating Delivery Systems with RT-Unstable Amorphous Components.

A Demethylation-Switchable Aptamer Design Enables Lag-Free Monitoring of mA Demethylase FTO with Energy Self-Sufficient and Structurally Integrated Features.

Cellular context profiling of modification effector proteins is critical for an in-depth understanding of their biological roles in RNA -methyladenosine (mA) modification regulation and function. However, challenges still remain due to the high context complexities, which call for a versatile toolbox for accurate live-cell monitoring of effectors. Here, we propose a demethylation-switchable aptamer sensor engineered with a site-specific mA (DSA-mA) for lag-free monitoring of the mA demethylase FTO activity in living cells.

OptoLacI: optogenetically engineered lactose operon repressor LacI responsive to light instead of IPTG.

Optogenetics' advancement has made light induction attractive for controlling biological processes due to its advantages of fine-tunability, reversibility, and low toxicity. The lactose operon induction system, commonly used in Escherichia coli, relies on the binding of lactose or isopropyl β-d-1-thiogalactopyranoside (IPTG) to the lactose repressor protein LacI, playing a pivotal role in controlling the lactose operon. Here, we harnessed the light-responsive light-oxygen-voltage 2 (LOV2) domain from Avena sativa phototropin 1 as a tool for light control and engineered LacI into two light-responsive variants, OptoLacIL and OptoLacID.
