Granulovacuolar degeneration in the hippocampus and amyloid deposition in blood vessels might also be seen on tissue examination, but they are not required for the diagnosis (Figs. 1 to 3). Amyloid Plaques Although amyloid plaques or senile plaques may be classified further according to their ...
A senile plaque with amyloid core stained with methenamine-silver (A), immunohistochemistry against Aβ (B) and Congo red (C without and D with polarization) stains. Original magnification x 600. Advertisement 7. Identification and extraction of the amyloid fibril ...
Amyloid β Plaque Reduction With Antibodies Crossing the Blood-Brain Barrier, Which Was Opened in 3 Sessions of Focused Ultrasound in a Rabbit Model. J Ultrasound Med. 2017;36(11):2257-70.Alecou T, Giannakou M, Damianou C. Amyloid beta plaque reduction with antibodies crossing the blood-...
Plaque size distributions were compared with a χ2 test followed by the Kolmogorov–Smirnov test with Prism V5.04 software (GraphPad Software, San Diego, CA, USA). A Shapiro–Wilk test was performed to verify normal distribution of sample values. A threshold of Po 0.05 was considered to be ...
Statistical analysis was performed using Mann-Whitney U test. Results Average non-fasted blood glucose in hGly-Tg mice was 398±25mg/dL compared to 159±12mg/dL in normoglycemic (nGly)-Tg mice. Total Formic acid extracted A40 and A42 levels were significantly elevated by 28.8% and 17.1%...
Lanz TA, Hosley JD, Adams WJ, Merchant KM: Studies of Abeta pharmacodynamics in the brain, cerebrospinal fluid, and plasma in young (plaque-free) Tg2576 mice using the gamma-secretase inhibitor N2-[(2S)-2-(3,5-difluorophenyl)-2-hydroxyethanoyl]-N1-[(7S)-5-methyl-6-oxo -6,7-dihydro...
and clinical blood testing including electrolytes, white cell differential counts, and C-reactive protein. Bronchoscopy with bronchioalveolar lavage (5 × 50 mL of sterile and PBS) was performed according to clinical routine at Karolinska University Hospital, Solna. The obtained BALF was concen...
an endogenous antibody response was found in 70–80% of treated patients, and serum samples from treated patients specifically labeled Ab plaque cores in both APP23 transgenic mouse and AD brain sections, with intensity of plaque staining correlating with measured anti-Ab titers in blood (Winblad...
