Background: Alzheimer's Disease (AD) is a neurodegenerative disease, characterized by a decrease in cognitive and behavioral functions of patients. Between the multiple potential disease-modifying therapeutics for AD, we have monoclonal antibodies as aducanumab, lecanemab, and donanemab. Recent results from the TRAILBLAZER-ALZ trial, highlighted donanemab as a promising monoantibodies treatment of early symptomatic AD.

Both VY-TAU01 and its parental mouse IgG1 mAb Ab-01 target an epitope in the C-terminus of tau, bind pathological tau with high affinity and selectivity over wild-type tau, block paired helical filament seed-induced tau aggregates in vitro, and selectively stain tau tangles in AD and P301S mouse (C57/B6J-Tg[Thy1-MAPT*P301S]2541Godt) brain. Ab-01 robustly inhibits seeding and propagation of pathological tau in a P301S mouse seeding model.

In these clinical studies, several plasma biomarkers assessments (Aβ42/40 ratio, p-tau181, GFAP, and p-tau217) showed improvements comparing lecanemab with placebo. Herein, we utilized modelling and simulations to evaluate the long-term effects of lecanemab on biomarkers of neurodegeneration in plasma.

Objectives: Total thyroxine (TT4) evaluation is the most commonly used first-line test for the diagnosis and monitoring of cats with hyperthyroidism. Vcheck T4 is a point-of-care immunoassay that measures TT4 using a Vcheck V200 analyser. This study aimed to evaluate the analytic performance of the Vcheck T4 assay in feline sera and the agreement in the classification of normal, high and low TT4 concentrations of Vcheck T4 with those measured by an enzyme immunoassay (EIA).

Background: The serum calcification propensity test (or T50 test) might become a standard tool for the assessment of vascular calcification risk and T50 might be a valuable biomarker in clinical trials of treatments intended to slow the progression of vascular calcification. Literature data suggest that non-calcium-containing phosphate binders can influence T50 in chronic dialysed patients. However, it is not clear whether similar interventions are effective in patients at earlier stages of chronic kidney disease (CKD).
