When Does Alzheimer's Disease Start? Plasma Aβ42/40 Assays Show Steep Changes at Aβ‐PET Centiloid 15, Mean Age of 66 Years

open access: yesAnnals of Neurology, EarlyView.
Objective Sporadic late‐onset Alzheimer's disease (AD) is characterized by a long pre‐clinical phase where amyloid‐beta (Aβ) and tau begin to accumulate in the brain. The primary objective was to determine the age at which AD starts by finding the average population age when both positron emission tomography (PET) Aβ (Aβ‐PET) and plasma Aβ42/40 become ...

Tau Pathology in Alzheimer's Disease Uniquely Affects Sulcal Depths

open access: yesAnnals of Neurology, EarlyView.
Objective Though it is widely known that tau deposition affects brain structure, the precise localization of these effects is poorly understood, especially in relation to gyral and sulcal anatomy. We investigated whether tau pathology in Alzheimer's disease (AD) preferentially affects sulci, and particularly sulcal depths.

Protein‐Template Gold Nanoclusters Induce Differentiation and Modify the Functional Properties of Primary Astrocytes

open access: yesAdvanced NanoBiomed Research, EarlyView.
The incubation of primary astrocytes with fAuNCs‐BSA induces: (A) long‐term effects including fAuNCs‐BSA internalization, red cell fluorescence, differentiation, upregulation of Ca2+ signaling, Cl‐current, and cell volume regulation. B) Short‐term (200 ms) stimulation with UV LED light increases in Ca2+ signaling and inhibition of K+ current. Astrocyte

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

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
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 ...
