Abstract:
A 67-year-old woman was admitted to our hospital with progressive aphasia. There was no family history of similar diseases or any history of dura transplantation. Cranial magnetic resonance imaging (MRI) showed high signal areas in the temporal and parietal cortex predominantly on the left side on both T2-weighted images and on diffusion-weighted images. There were no periodic synchronous discharges observed on the electroencephalogram. As prion protein gene codon 180 point mutation (Val/Ile) was detected, we diagnosed her as having Creutzfeldt-Jakob disease (CJD). The characteristics of CJD of this type differ from those of sporadic CJD. To date, few papers on CJD with point mutation of codon 180 have been reported from Japan.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.

Amyloid Fibrils
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining, normally used to...
