Ferschmann C, Messerschmidt K, Gnorich J, Barthel H, Marek K, Palleis C, et al.
Eur J Nucl Med Mol Imaging . 2024 Feb; 51(7):1909-1922. PMID: 38366196
Purpose: We hypothesized that severe tau burden in brain regions involved in direct or indirect pathways of the basal ganglia correlate with more severe striatal dopamine deficiency in four-repeat (4R)...

Cancers (Basel) . 2024 Jan; 16(1). PMID: 38201600
Background: The gastrin-releasing peptide receptor (GRPr) is highly overexpressed in several solid tumors, including treatment-naïve and recurrent prostate cancer. [Ga]Ga-RM2 is a well-established radiotracer for PET imaging of GRPr, and...

Bader I, Bader I, Lopes Alves I, Garcia D, Vellas B, Dubois B, et al.
Alzheimers Res Ther . 2023 Nov; 15(1):189. PMID: 37919783
Background: The mismatch between the limited availability versus the high demand of participants who are in the pre-dementia phase of Alzheimer's disease (AD) is a bottleneck for clinical studies in...

Villemagne V, Leuzy A, Sanabria Bohorquez S, Bullich S, Shimada H, Rowe C, et al.
Alzheimers Dement (Amst) . 2023 Jul; 15(3):e12454. PMID: 37424964
Introduction: Recently, an increasing number of tau tracers have become available. There is a need to standardize quantitative tau measures across tracers, supporting a universal scale. We developed several cortical...

Haque F, Ryde J, Broughton L, Huang C, Sethi S, Stephens A, et al.
ERJ Open Res . 2023 May; 9(3). PMID: 37143830
Background: Clinical prediction rules (CPRs) developed to predict adverse outcomes of suspected pulmonary embolism (PE) and facilitate outpatient management have limitations in discriminating outcomes for ambulatory cancer patients with unsuspected...

Collij L, Farrar G, Garcia D, Bader I, Shekari M, Lorenzini L, et al.
Front Neurol . 2023 Feb; 13:1063598. PMID: 36761917
Background: Amyloid-β (Aβ) accumulation is considered the earliest pathological change in Alzheimer's disease (AD). The Amyloid Imaging to Prevent Alzheimer's Disease (AMYPAD) consortium is a collaborative European framework across European...

Biosens Bioelectron . 2023 Jan; 224():115030. PMID: 36603283
Organ-on-a-chip platforms have potential to offer more cost-effective, ethical, and human-resembling models than animal models for disease study and drug discovery. Particularly, the Blood-Brain-Barrier-on-a-chip (BBB-oC) has emerged as a promising...

Alzheimers Dement . 2022 Dec; 19(6):2397-2407. PMID: 36478646
Introduction: We investigated amyloid-burden quantification in a mixed memory clinic population. Methods: [ F]Florbetaben amyloid-PET (positron emission tomography) scans of 348 patients were visually read and quantified using the Centiloid...

Alzheimers Res Ther . 2022 Jul; 14(1):105. PMID: 35897078
Background: The ability of F-PI-2620 PET to measure the spatial distribution of tau pathology in Alzheimer's disease (AD) has been demonstrated in previous studies. The objective of this work was...
