Background: Intrathecally (IT) delivered antisense oligonucleotides (ASOs) are promising therapies that can reduce tau pathology in Alzheimer's Disease (AD). However, current plasma and CSF sampling methods to estimate brain tissue exposure of ASOs are inherently limited, hampering ASO clinical developmental plans. We developed the PET tracer [F]BIO-687, which binds ASO conjugates (ASO-Tz) in vivo, allowing us to image ASO distribution in a living brain using "pretargeted" imaging.

Structural basis for the conformational protection of nitrogenase from O.

The low reduction potentials required for the reduction of dinitrogen (N) render metal-based nitrogen-fixation catalysts vulnerable to irreversible damage by dioxygen (O). Such O sensitivity represents a major conundrum for the enzyme nitrogenase, as a large fraction of nitrogen-fixing organisms are either obligate aerobes or closely associated with O-respiring organisms to support the high energy demand of catalytic N reduction. To counter O damage to nitrogenase, diazotrophs use O scavengers, exploit compartmentalization or maintain high respiration rates to minimize intracellular O concentrations.

Neurodevelopmental disorders in children with cleft lip and palate: a systematic review.

Individuals with orofacial clefts (OFCs) may be at an increased risk of developing autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD). This systematic review provides a summary of the most recent data regarding the prevalence of ASD and ADHD in the OFC population and compares this to the general paediatric population. Multiple databases were searched including PubMed/Medline and Embase in July 2024, following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines and was registered in PROSPERO (CRD42024565219).

Effects of Retinol, Natural Pea Peptide and Antioxidant Blend in a Topical Formulation: In Vitro and Clinical Evidence.

Introduction: Retinol has a long history of treating skin conditions, including photoaging. However, skin irritation with repeated use of retinol is well documented. The present study assessed the effectiveness of a novel topical formulation, referred to as retinol topical formulation (RTF), to improve the quality of skin health.
