Diffusion-weighted (DWI) magnetic resonance imaging (MRI) is a highly sensitive and specific test for diagnosis of sporadic Jakob-Creutzfeldt disease (sCJD); however, the neuropathologic origin of DWI signal abnormalities including other clinical features has not been well defined. We describe a case of sCJD with brain MRI taken 15 days before death, which(More)
In prion-infected mice, both the Notch-1 intracellular domain transcription factor (NICD) and the disease-causing prion protein (PrP(Sc)) increase in the brain preceding dendritic atrophy and loss. Because the drug LY411575 inhibits the gamma-secretase-catalyzed cleavage of Notch-1 that produces NICD, we asked whether this gamma-secretase inhibitor (GSI)(More)
With the discovery of the prion protein (PrP), immunodiagnostic procedures were applied to diagnose Creutzfeldt-Jakob disease (CJD). Before development of the conformation-dependent immunoassay (CDI), all immunoassays for the disease-causing PrP isoform (PrPSc) used limited proteolysis to digest the precursor cellular PrP (PrPC). Because the CDI is the only(More)
Human prion diseases can be caused by mutations in the prion protein gene PRNP. Prion disease with mutations at codon 188 has been reported in 6 cases, but only 1 had the T188R mutation and it was not pathologically confirmed. We report the clinical, neuropsychologic, imaging, genetic, and neuropathologic features of a patient with familial(More)
551 Background: T1abN0M0 BC has a low recurrence risk. In contrast, HER2+ BC has an increased risk of local/distant recurrence. In small case series of T1abN0M0 HER2+ BCs from tertiary referral centers, recurrence rates have ranged from 8-23%. Data on sites of recurrence have been limited. While adjuvant chemotherapy plus trastuzumab provides a relative(More)
