re: 4. aricept not that helpful for alzheimer's. 4 PBT was heavily overbought on the Nasdaq 2 days ago and traders have dumped some shares back overnight there, causing a fall there and here.

As far as I know, PBT is the only Australian Co in that field and in my opinion, they got something there.

+ + + "Also at ICAD, on Wednesday July 21, Dr. Bush is scheduled to give an invited lecture that will
review the basic neuroscience describing the involvement of brain copper and zinc in Alzheimer
pathology.

+ + + New data is expected to be presented on the interaction of cholesterol with betaamyloid and brain metals, which may play a key role in the sequence of events that leads to dementia.

The possibility that beta-amyloid participates in the functional regulation of copper levels in health will be discussed.
(*MPACs, or Metal-Protein Attenuating Compounds are compounds that bind metals to prevent
their interactions with proteins.)".

So that could be interesting with that US lecture coming up.

PBT often sinks back after a period with no announcements but it is not the only BIO doing that.

Most Bios have been hit somewhat lately.
