A Systematic Comparison of Alpha‐Synuclein Seed Amplification Assays for Increasing Reproducibility
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Seed amplification assays (SAAs) enable ultrasensitive detection of misfolded α‐synuclein across biofluids and tissues. Yet, heterogeneity in protocols limits cross‐study comparability and clinical translation. Here, we review α‐synuclein SAA methods and their performance across various biological matrices.

Mycenaean Seals and Sealings [PDF]
, 2012 Abstract After the introduction of a sealing system from the Near East into southern Greece in the Early Helladic period and the destruction of that culture, there is no demonstrable sign that seals were used on the Greek mainland until the sudden appearance of seals in the Mycenae Shaft Graves at the end of the Middle Helladic period ...
