The recent technology of amplification of DNA sequences by the polymerase chain reaction (PCR) has already proved to be a very useful tool for the analysis of variable number of tandem repeat (VNTR) loci. Short tandem repeat (STR) loci appear as other promising PCR-based identification systems. In fact, DNA typing based on PCR amplification of STRs is very sensitive and allows to overcome major problems encountered when using the RFLP method, such as typing of very small amounts of DNA, highly degraded DNA or mixtures of DNA from more than one individual. Two STR systems, HUMTH01 (a tetranucleotide repeat (AATG) sequence located on chromosome 11) and HUMFES/FPS (a tetranucleotide repeat (ATTT) sequence located on chromosome 15) were investigated in order to determine allele and genotype frequencies for a French caucasian population sample. HUMTH01 and HUMFES/FPS alleles were amplified by the use of PCR and amplified STR sequences were analyzed on 6% Hydrolink Long Ranger gels and visualized by silver staining. The study was conducted on a sample of unrelated individuals (N approximately 190) randomly selected from the French caucasian population. The genotype distributions met Hardy-Weinberg expectations for both HUMTH01 and HUMFES/FPS STR systems. Furthermore, an additional allele, never reported before was observed at the HUMFES/FPS locus: it migrates as an allele containing 7 repeat units and corresponds to the smallest allele identified for this locus.

Allele and genotype frequencies for 7 tetrameric short tandem repeat loci were determined in a Spanish population sample (N = 186-244) using PCR and subsequent analysis of the PCR products by denaturing polyacrylamide gel electrophoresis followed by silver staining. The loci were HUMFES/FPS, HUMVWA, HUMTHO1, HUMF13B, HUMCSF1PO, HUMF13A1 and HUMTPOX and all loci met Hardy-Weinberg expectations. In addition, little evidence was found for association of alleles among the 7 loci. Thus the allele frequency data can be used in identity testing to estimate the frequency of a multiple PCR-based DNA profile in the Spanish population.

Because of the well established role that tyrosine phosphorylation (tyr phos) plays in growth factor signalling and regulating cell growth, we hypothesized that cardiac hypertrophy might be associated with altered tyr phos of certain cellular proteins in the heart. Furthermore, we hypothesized that angiotensin II (ang II), a putative growth factor for cardiac cells, might be useful as a probe to highlight any differences in intracellular signalling between normal and hypertrophied hearts. The heart and, for comparison, skeletal muscle, from Dahl S rats, which are predisposed to cardiac hypertrophy, and Dahl R rats, which are not, were examined. Antiphosphotyrosine immunoprecipitation and immunoblotting of heart cell extracts revealed the presence of a constitutively tyr phos 120 kDa cytosolic protein. Hearts from Dahl R rats on a high salt diet displayed a smaller amount of constitutive tyr phos of this protein. In the hearts of both Dahl R and S rats maintained on low salt diets there was little evidence of constitutive tyr phos of this protein. Ang II induced tyr phos of this protein in Dahl S rats on a low salt diet and Dahl R rats on a high salt diet, both of which show mild cardiac hypertrophy. In contrast, the markedly hypertrophied ventricle showed a minimal response to Ang II. Thus the severity of cardiac hypertrophy correlated directly with the tyr phos level of this protein. In an attempt to identify this protein, immunoblotting was carried out with antibodies to the signal transducing proteins rasGAP, JAK2 iNOS, p125FAK, and the Src substrate, pp120, but all proved negative. Ang II also stimulated an increase in tyr phos of proteins with apparent molecular masses of 42, 55, and 69 to 85 kDa in hearts from Dahl S rats on high salt diet. By comparison, there was no 120 kDa tyr phos protein in skeletal muscle even in response to Ang II. Silver stained sodium dodecyl sulfate gels demonstrated that this 120 kDa tyr phos protein is present in substantial amounts in the ventricles of rats fed high salt diets. Thus cardiac hypertrophy is characterized by an abundant 120 kDa cytosolic tyr phos protein, which is apparent with Ang II stimulation in milder degrees of cardiac hypertrophy, and is most likely an as yet uncharacterized protein.

Sixty-one consecutive patients in the Intensive Care Unit requiring central venous lines (CVC) for five or more days were randomized to receive either a standard triple lumen CVC (STD/CVC) or a silver sulphadiazine and chlorhexidine impregnated CVC (SSD/CVC). Data from the 54 patients who completed the trial show a reduced infection rate (positive tip culture) in the SSD/CVC group (4 out of 28) compared to the STD/CVC group (10 out of 26) (P < 0.05). In addition, the new Fibrin Analysing System (FAS) brush was evaluated and used to determine the presence of infection in all the CVCs (STD/CVC and SSD/CVC combined, n = 54) at day 3 (i.e. early warning of CVC colonization/infection) and at the time of removal of the CVC. The FAS brush was able to detect an infected CVC on only one occasion on day 3 out of the 14 CVC tips which were later found to be colonized/infected at the time of removal. The sensitivity of the FAS brush in detecting colonized/infected CVCs at the time of CVC removal compared with CVC tip culture was 21% with a specificity of 100%. These findings would currently not support the routine use of the FAS brush in determining CVC infection/colonization.

We present a Hungarian population study for six tetrameric short tandem repeat (STR) loci employing multiplex PCR amplification, electrophoresis of the PCR products in DNA sequencing gels and subsequent detection of allelic fragments by silver staining. The loci were HUMVWFA31, HUMTH01, HUMCSF1PO, HUMFES/ FPS, HUMTPOX, and HUMHPRTB. All loci met Hardy-Weinberg expectations in the examined Hungarian Caucasian population sample (N = 223 individuals). In addition, there was no evidence for association of alleles among the five autosomal loci HUMVWFA31, HUMTH01, HUMCSF1PO, HUMFES/FPS, and HUMTPOX.

We have developed a triplex PCR method for D3S1359, HumTH01 and HumTPO tetranucleotide loci and a duplex PCR method for HumFES/FPS and HumvWA31A tetranucleotide loci using high resolution polyacrylamide gel electrophoresis and silver staining. The methods were evaluated for paternity testing and individual identification and allele frequencies at these loci are reported for 189-3387 unrelated individuals in the Finnish population. The D3S1359 locus, especially, was found to be a highly informative locus. Seventeen alleles were found in the D3S1359 locus with a highest observed allele frequency of 0.199, a high exclusion power (PE) in paternity testing (0.78) and a high observed heterozygosity (0.89). The combined PE for these five loci was 0.99.

Allele and genotype frequencies for four tetrameric short tandem repeat (STR) loci, HumFES/FPS, HumFOLP23, HumGABRB15, and HumCYAR04, have been determined by polymerase chain reaction (PCR) amplification and subsequent polyacrylamide gel electrophoresis from approximately 200 genetically unrelated Koreans. This method allows a single base pair resolution and rapid typing with silver staining. The allele and genotype distributions satisfy Hardy-Weinberg expectation. Also, these STR loci have proven to be useful for forensic analyses and paternity tests in which the variable number of tandem repeat (VNTR) loci have some limitations.

A population study of unrelated individuals from North Poland (Gdansk area) was carried out to investigate the allele distributions of the five STR systems HUMCD4, HUMFES/FPS, HUMVWA31, HUMTH01 and ACTBP2. PCR products were separated on horizontal non-denaturing polyacrylamide gels followed by silver staining. For all STR systems analysed the distribution of observed phenotypes did not deviate from Hardy-Weinberg equilibrium. A comparison of allele distributions between Polish and other European Caucasian population samples is presented.

A simple and rapid method for the determination of some trace element impurities in high purity silver, combining the isolation of analytes from the silver matrix with selective precipitation followed by ICP-MS determination was developed. On the basis of an extreme difference in the solubilities of the chlorides of silver and the other accompanying trace elements, silver can be separated completely through the addition of hydrochloric acid. The sample of silver was at first dissolved in 7 M nitric acid followed by addition of hydrochloric acid to remove the silver matrix by formation of a silver chloride precipitate, while leaving the trace element impurities in the solution, which was subsequently analysed by ICP-MS. Eleven elements (Al, Au, Cd, Co, Cu, Fe, Mg, Mn, Ni, Pb and Sn) were determined with good accuracy and precision. The limits of detection (based on the 3 sigma criterion) of these elements were 10(-1)-10(-3) ng g-1. The proposed method was successfully applied to the determination of metal impurities in high-purity silver samples (EM9465 and EM 9343) and validated by the analysis of NIST SRM 8171 (Fine Silver FS 14).

We investigated parental origin of rearranged chromosomes 9 and 22 (9q + and 22q -) in five patients with Ph-positive chronic myeloid leukemia (CML) using the C-banding and silver-staining methods of nucleolus organizer regions, respectively; of rearranged chromosome 21 (21q +) in seven patients with t(8;21)-positive acute myeloid leukemia (AML); and of rearranged chromosome 15 (15q +) in six patients with t(15;17)-positive AML. It was found that these rearranged chromosomes can be of either paternal or maternal origin. Although the number of patients examined was small, these results indicate that the genes rearranged as a result of these chromosome translocations (ABL, BCR, AML-1 and PML) are not genomically imprinted.
