Are cerebrospinal fluid dehydroepiandrosterone levels correlated with brain dehydroepiandrosterone levels , elevated in Alzheimer 's disease , and related to neuropathological disease stage?
These findings indicate that CSF DHEA and pregnenolone levels are correlated with temporal cortex brain levels of these neurosteroids and that CSF DHEA is elevated in AD and related to neuropathological disease stage. Neurosteroids may thus be relevant to the pathophysiology of AD.
Corroding activity detection assays confirmed that Enterobacteriaceae (members of the gamma-proteobacteria) were involved in biocorrosion of metallic material in marine conditions.
