Background Differential diagnosis of parkinsonian sindrome is a major challenge in movement disorders because at the onset there is an overlapping of signs and syntoms. From a neuropathological point of view, parkinsonism may be related to a degeneration of the nigrostriatal pathway or the neurodegenerative process may be more widespread [1,2]. In the early course of the a disease presenting wi...
We define sporadic rules as those with low support but high confidence: for example, a rare association of two symptoms indicating a rare disease. To find such rules using the well-known Apriori algorithm, minimum support has to be set very low, producing a large number of trivial frequent itemsets. We propose “Apriori-Inverse”, a method of discovering sporadic rules by ignoring all candidate i...
OBJECTIVE Screening plasma samples from patients with sporadic Creutzfeldt-Jakob disease (CJD) to discover diagnostic biomarkers. METHODS Plasma samples were collected from 17 patients with sporadic CJD, 17 patients with Alzheimer disease (AD), and 20 healthy subjects. A 2-phase screening was carried out using quantitative protein mass spectrometry. The putative sporadic CJD biomarkers were t...
Both ulcerative colitis (UC)-related and sporadic colorectal cancers are thought to evolve through a multistep process of genomic instability, accumulation of genomic alterations, and clonal expansion. This process may involve different genomic changes in UC-related cancers than in sporadic cancers because of the origin of UC-related cancers in an inflammatory field. This study was designed to ...
