The mtDNA genome has been implicated as playing a pivotal role in determining the longevity and success of the human lifespan. A PCR-RFLP methodology was used to identify polymorphic restriction enzyme sites within a 2643 bp region of the mtDNA genome and a table of genetic haplotypes for a healthy aged and a younger control cohort of patients was(More)
These authors contributed equally to this work. ABSTRACT Parkinson's disease (PD) and other related disorders are characterized by the accumulation of fibrillar aggregates of α-synuclein protein (α-syn) inside brain cells. It is likely that the formation of α-syn aggregates plays a seminal role in the pathogenesis of at least some of these diseases, because(More)
BACKGROUND Animals can act as a reservoir and source for the emergence of novel meticillin-resistant Staphylococcus aureus (MRSA) clones in human beings. Here, we report the discovery of a strain of S aureus (LGA251) isolated from bulk milk that was phenotypically resistant to meticillin but tested negative for the mecA gene and a preliminary investigation(More)
The frequency of various allele types of the class I Major Histocompatibility Complex (MHC) genes HLA-A and HLA-B were compared between pathologically confirmed groups of late and early-onset Alzheimer's disease (AD) and a control group. DNA was extracted from frozen brain tissue and the highly polymorphic second and third exons of the HLA-A and HLA-B genes(More)
cDNA clones of the largest RNA transcript of the canine distemper and measles morbilliviruses were characterized. This presumably codes for the L protein of these viruses. mRNA 4 was identified as coding for the haemagglutinin protein of measles virus. From an analysis of readthrough transcripts representing tandem copies of two or three genes we(More)
The release of cytokines is of crucial importance in the regulation of the type and magnitude of the immune response in the elderly. A number of studies have shown different levels of cytokine production in the elderly. In the present study, a range of polymorphisms were chosen within the genes of cytokines (IL-2, IL-6, IL-8, IL-10, IL-12 and IFN-gamma)(More)
The nucleotide sequences of the phosphoprotein (P)/V/C and matrix (M) protein genes of phocine distemper virus (PDV) have been determined and the deduced amino acid sequences of the proteins derived from these genes compared with those of the other morbilliviruses. The 1655 nucleotides of the P gene encode a phosphoprotein of 507 amino acid residues (from(More)
Polymorphism of the human leukocyte antigen has been implicated in a number of autoimmune disorders including ageing. In the course of the present study, no association of the human leukocyte antigen (HLA)-A1, B8, DR3 haplotype with a male Irish aged population, as previously reported, was observed. Two polymorphic nucleotides in the TNF cluster (G-308A(More)
This report describes the application of reference strand-mediated conformational analysis (RSCA), a novel DNA typing technique, for the identification of clinically significant fungal pathogens. RSCA is a heteroduplex-based conformational method which relies on detecting differences in the DNA conformation of heteroduplexes generated in this study by the(More)
Recently it has been reported that a missense G(88)C mutation within exon 3 and a missense G(209)A mutation within exon 4 of the alpha-synuclein gene were linked to familial Parkinson's Disease (PD). We decided to investigate if these and any other mutations in exons 3 and 4 of the alpha-synuclein gene could be detected in sixty two sporadic PD and dementia(More)
