Temporal Modeling of Amyloid and Tau Trajectories in Alzheimer's Disease Using PET and Plasma Biomarkers

Annals of Neurology, Volume 99, Issue 6, Page 1438-1451, June 2026.
Objective This study aimed to compare positron emission tomography (PET) and plasma‐based temporal modeling of amyloid and tau biomarkers in Alzheimer's disease. Methods Longitudinal amyloid PET (n = 1,097, mean age ± SD = 72.5 ± 7.38 year, 51.4% male), 18F‐flortaucipir tau‐PET (n = 230, 74.3 ± 7.18 year, 52.2% female), and Fujirebio Lumipulse plasma p‐

Transient Transfection of Rolling‐Circle Amplified DNA in Biomanufacturing‐Relevant Mammalian Cell Lines: A Comparison of Transfection Conditions for Optimal Protein Expression

Biotechnology and Applied Biochemistry, Volume 73, Issue 3, Page 1358-1367, June 2026.
ABSTRACT Rolling‐circle amplification (RCA) is a completely synthetic and rapid mechanism for scaling‐up bulk DNA that eliminates requirements for large‐scale bacterial fermentation. Several reports have described the surprising ability of large unprocessed (hyperbranched) rolling circle‐amplified DNA (RCA DNA) to effectively transfect cultured cells ...

Wurtzite‐Chalcopyrite Crystal Polymorphism in CuGaS2 Nanoparticles Dictates the Localized Surface Plasmon Resonance

Chemistry – A European Journal, Volume 32, Issue 21, 1 June 2026.
Crystal phase‐ and size‐selective synthesis of chalcopyrite and wurtzite‐type CuGaS2 NPs was successfully achieved. They exhibited clear LSPR in the NIR region. The extinction coefficient of chalcopyrite was three times higher than that of wurtzite due to its greater symmetry and dipole moment. These results will enable precise control of the plasmonic

Decoding Choroid Plexus Pathology in Alzheimer's Disease: A Longitudinal Radiomics Approach for Prodromal Identification and Risk Stratification

CNS Neuroscience &Therapeutics, Volume 32, Issue 6, June 2026.
A machine learning model utilizing choroid plexus (CP) radiomics effectively distinguishes Alzheimer's disease (AD) from mild cognitive impairment (MCI) and predicts MCI‐to‐AD progression risk. After integration with clinical features, the model exhibits strong predictive performance. The CP radiomics features correlate significantly with cognitive and
