A new method for the identification of fetal hemoglobin (Hb F) in blood stains by reverse-phase high performance liquid chromatography is described. Differentiation between fetal and adult blood stains is based on the existence of γ-chain peaks which are characteristic of Hb F. Very few γ chains appeared on chromatograms of all the adult blood stains(More)
We examined whether methamphetamine (MAP) induced apoptotic cell death in vivo. Male Wistar rats were injected intraperitoneally with 25 mg MAP/Kg body weight and were sacrificed at 4, 8 and 24 h. As early as 4 h after a single dose of MAP, DNA ladder bands representing DNA fragmentation into multiples of the internucleosomal DNA length of about 180 by were(More)
A method using reverse-phase high-performance liquid chromatography (HPLC) for the identification of fetal hemoglobin (Hb F) and the simultaneous estimation of bloodstain age is described. Umbilical cord and neonatal bloodstains can be differentiated from adult stains by the presence of γ-globin chains which are characteristic of Hb F. With this method,(More)
To investigate the direct effects of methamphetamine (MAP) on cardiac lesions seen in MAP abusers, isolated adult rat ventricular cardiomyocytes (ARCs) were exposed to MAP (0.05–1.0 mM) in medium 199 containing 10% fetal calf serum. Isolated ARCs attached to laminin-coated substrata and began to spread into polygonal shapes with pseudopodia at day 6 in(More)
From the perspective of comparative morphology, the distribution of non-monoaminergic neurons in the common marmoset (Callithrix jacchus) was investigated using an immunohistochemical method with specific antibodies to tyrosine hydroxylase (TH) and aromatic-L-amino acid decarboxylase (AADC).TH-immunoreactive (IR) neurons (but not AADC-IR) neurons were(More)
A procedure utilizing Chelex 100, chelating resin, was adapted to extract DNA from dental pulp. The procedure was simple and rapid, involved no organic solvents, and did not require multiple tube transfers. The extraction of DNA from dental pulp using this method was as efficient, or more so, than using proteinase K and phenol-chloroform extraction. In this(More)
The authors report four cases in which severely damaged human remains were identified by mitochondrial DNA (mtDNA) sequencing. Degraded DNA was extracted from highly adipoceratous tissues using the phenol-chloroform method and polymerase chain reaction amplified for sequencing of two hypervariable regions, hypervariable region 1 and hypervariable region 2,(More)
The utility of Y-STR haplotype and mtDNA sequence in personal identification from human remains is demonstrated. In five cases, severely damaged human remains were identified by Y-chromosomal short tandem repeat (STR) (Y-STR) haplotyping and mitochondrial DNA (mtDNA) sequencing. DNA was extracted from highly adipoceratous tissues using the phenol-chloroform(More)
The influence of repeated hypoxia on the development of haemoglobin (Hb) subtypes and on extramedullary haematopoiesis (EMH) was investigated in young Wistar rats of different ages. The rats were exposed to hypercapnic/hypoxic and to “simple” hypoxic conditions. The results obtained were compared to those of an untreated age-matched control group. Different(More)
