The heme compound found in deoxyribonucleic acid (DNA) extracted from bloodstains, which is regarded as a major inhibitor of polymerase chain reaction (PCR), was characterized in comparison with alkaline and acid hematin, histidine and ammonia hemochromogens, and globin and serum albumin hemochromogens digested by proteinase K. Alkaline and acid hematin(More)
Dentatorubral and pallidoluysian atrophy (DRPLA) is an autosomal dominant neurodegenerative disorder associated with the expansion of a CAG repeat at chromosome band 12p13. Epidemiological studies have demonstrated an increased prevalence of DRPLA in Japan, although several DRPLA kindreds of non-Japanese ancestry have been identified. To define the(More)
Potential bioactivated neurotoxicants, 2-N-methyl-beta-carbolinium and 2,9-N,N'-dimethyl-beta-carbolinium ions, as well as N-methylation activities which form these charged species, were analyzed for the first time in the parietal association cortex and the substantia nigra of human brain using GC/MS and HPLC. The brains were taken during forensic autopsies(More)
Scalp electroencephalograms (EEGs) of brain dead patients are macroscopically flat under 7 or 10 microV/mm electroencephalograph sensitivity, but significant noises are detected in EEGs under 2 microV/mm sensitivity, interfering with the analysis. EEGs of 20 brain dead patients (17-76 years old) were therefore analyzed quantitatively as equivalent electric(More)
Nasopharyngeally-derived electroencephalogram (EEG) was recorded and digitized in 12 "brain death" subjects with flat-line scalp EEG and loss of auditory brain stem response. The nasopharyngeal EEGs of these cases were classified into three types: Type Ia with complete flat-line, Type Ib with almost but incomplete flat-line EEG, and Type II with(More)
