Perfluoroalkyl (RF) titanocene reagents [Cp2Ti(III)RF] synthesized via [Cp2Ti(III)Cl] rather than [Cp2Ti(II)] show new types of perfluoroalkylation reactions. The [Cp2Ti(III)RF] reagents exhibit a wide variety of reactivity with carbonyl compounds including esters and nitriles, and selectivities far higher than those reported for conventional RFLi and RFMgX reagents.

Background: Alzheimer's disease (AD) remains a formidable neurodegenerative challenge, characterized by profound cognitive decline. Despite decades of research, effective disease-modifying therapies are elusive. Recent advances in molecular neuropharmacology have unveiled potential therapeutic targets for AD, offering renewed hope.

Background: Understanding the fundamental differences between the human and pre-human brain is a prerequisite for designing meaningful models and therapies for AD. Expressed CHRFAM7A, a human restricted gene with carrier frequency of 75% in the human population predicts profound translational significance.

Method: The physiological role of CHRFAM7A in human brain is explored using multiomics approach on 600 post mortem human brain tissue samples (ROSMAP).

Introduction: Lecanemab (LEQEMBI®), a humanized monoclonal antibody targeting Amyloid-beta (Aβ) protofibrils, received full FDA approval in July 2023 for treating early-stage Alzheimer's disease (AD). This abstract highlights Tel Aviv Medical Center's (TLVMC) specialized infrastructure for early AD diagnosis and treatment and includes presenting baseline characteristics of initial patients opting for LEQEMBI®.

Methods: Outlining our clinics' operational experience in establishing the Center for advanced treatments for AD, treatment protocol, and a descriptive analysis of baseline assessment data including demographics, baseline Magnetic-Resonance-Imaging (MRI), Cerebrospinal-fluid (CSF)/PET biomarkers, pre-treatment cognitive evaluations (Mini-Mental-State-Examination (MMSE)/Montreal-Cognitive-Assessment (MoCA)), and Apolipoprotein-E (APOE) status.
