Recently, there has been much debate about what kinds of genetic markers should be implemented as new core loci that constitute national DNA databases. The choices lie between conventional STRs, ranging in size from 100 to 450 bp; mini-STRs, with amplicon sizes less than 200 bp; and single nucleotide polymorphisms (SNPs). There is general agreement by the(More)
Estimating the weight of evidence in forensic genetics is often done in terms of a likelihood ratio, LR. The LR evaluates the probability of the observed evidence under competing hypotheses. Most often, probabilities used in the LR only consider the evidence from the genomic variation identified using polymorphic genetic markers. However, modern typing(More)
Cultured mouse cerebellar granule cells differ from their rat counterparts in that they survive well when grown in non-depolarising medium (5 mM K(+)). However, when chronically stimulated by added glutamate agonists, including (RS)alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA), rat cerebellar granule cells also survive well in(More)
We have previously reported that, unlike their rat counterparts, the survival of mouse cerebellar granule cells is independent of chronic stimulation whether owing to elevated K(+)-induced depolarization or NMDA (N-methyl-D-aspartate) receptor activation. One explanation could be that during the critical period mouse granule cells are very sensitive to NMDA(More)
The effects of K(+)-induced membrane depolarization were studied on the survival and biochemical parameters in mouse and rat cerebellar granule cells grown in micro-well cultures. Cell numbers were determined by estimating DNA content using the Hoechst 33258 fluorochrome binding assay. DNA from degenerated cells was removed by prior DNAase treatment. These(More)
Insoluble aggregates of the amyloid beta-peptide (A beta) is a major constituent of senile plaques found in brains of Alzheimer disease (AD) patients. The detrimental effects of aggregated A beta is associated with an increased intracellular Ca2+ concentration ([Ca2+]i). We examined the effects of A beta(25-35) on [Ca2+]i and intracellular H+ concentration(More)
Six commercial preparations of human genomic DNA were quantified using six quantification methods including UV spectrometry, SYBR-green dye staining, slotblot hybridization with the probe D17Z1, and three TaqMan real-time PCR assays: Quantifilerk Human DNA Quantification kit, Quantifilerk Y DNA Quantification kit, and RB1 rt-PCR. In general, all methods(More)
Y chromosome short tandem repeats (Y-STRs) are valuable genetic markers in certain areas of forensic case-work. However, when the Y-STR DNA profile is weak, the observed Y-STR profile may not be complete--i.e. locus drop-out may have occurred. Another explanation could be that the stain DNA did not have a Y-STR allele that was detectable with the method(More)
We studied the effects of chronic K(+)-induced membrane depolarization and treatment with N-methyl-D-aspartate (NMDA) on cerebellar granule cells (CGCs) from weaver mutant mice and non-weaver litter-mates. The weaver mutation is a Gly-to-Ser substitution in a conserved region of the Girk2 G protein-coupled inward rectifying potassium channel [Patil N., Cox(More)
