Alleles of the STR systems HumFES/FPS, HumVWA and HumD21S11 were sequenced and analyzed. Sequence data revealed 3 different systems concerning the complexity of their sequence structure. HumFES/FPS belongs to the STR polymorphism with a simple repeat structure. Only 2 subtypes were found with a base substitution in the 5'-flanking region and no variation in the repeat region. In the STR system HumVWA the sequence structure of the repeat region is more complex, because 2 tetranucleotide units TCTA and TCTG were present. Additionally allele 14 revealed a completely different sequence structure leading to a different electrophoretic mobility. The repeat region of HumD21S11 is compound in structure. The possibility of variation at 3 positions leads to the occurrence of microheterogeneities in fragments of apparent length. In the upper allele range alleles arise with an additional incomplete TA-repeat.

Spontaneous activity and responses to sensory stimulation in ventrobasal (VB) thalamic neurons were studied in barbiturate-anesthetized rats through intracellular recordings. The recordings were carried out with micropipettes filled with K acetate KCl plus horseradish peroxidase (HRP), our KCl plus biocytin. Two types of spontaneous depolarizing events were observed: fast potentials (FPs), characterized by a low amplitude (5.3 +/- 1.8 mV [mean and standard deviation]), a fast rising slope (1.15 +/- 0.19 msec), and a short duration (8.47 +/- 0.89 msec); and slow potentials (SPs), characterized by a larger and more variable amplitude (9.1 +/- 5.6 mV) and a longer duration (62.5 +/- 27.2 msec), with a slower rising slope (26.2 +/- 6.4 msec). The potential changes elicited by sensory stimuli delivered manually were similar to those elicited by electronically gated short air jets to the receptive fields. FPs were evoked by sensory stimulation in 62.7% of the recorded neurons, and SPs in the remaining 37.3%. Both types of events could occur spontaneously in the same neuron, but only one of them was triggered by stimulation of the receptive field. Five neurons that were successfully stained with either HRP or biocytin were studied in detail. All were medium-sized stellate cells, with spine-like appendages sparsely distributed along slender radiating dendrites. The axons took a rostrolateral course across the VB, and all but one left one or two thin collaterals in the reticular thalamic nucleus. No overt morphological differences were observed between VB neurons that responded with FPS or SPs to sensory stimulation.

Limits on the exposure to high-peak-power, short-duration microwave pulses have only recently been adopted. Additional data, however, are needed to understand the effects that may be produced by exposure to high-peak-power pulsed microwaves. Four male rhesus monkeys (Macaca mulatta) were trained on an operant task for food pellet reward to investigate the behavioral effects of very high-peak-power 5.62 GHz microwaves. The operant task required monkeys to pull one plastic lever on a variable interval schedule (VI-25 s) and then respond to color signals and pull a second lever to obtain food. The monkeys were conditioned to perform a color discrimination task using one of three colors displayed by a fiber-optic cable. A red signal was the discriminative stimulus for responding on the first lever. A response on the second lever when a green signal was presented (1 s duration) delivered a food pellet. If a response on the second lever was made in the presence of a white signal, a 30-s timeout occurred. While performing the behavioral task, the monkeys were exposed to microwave pulses produced by either a military radar (FPS-26A) operating at 5.62 GHz or the same radar coupled to a Stanford linear energy doubler (SLED) pulse-forming device (ITT-2972) that enhanced peak power by a factor of nine by adding a high power pulse to the radar pulse. The effects of both types of pulses were compared to sham exposure. Peak field power densities tested were 518, 1270, and 2520 W/cm2 for SLED pulses and 56, 128, and 277 W/cm2 for the radar pulses. The microwave pulses (radar or SLED) were delivered at 100 pps (2.8 microseconds radar pulse duration; approximately 50 ns SLED pulse duration) for 20 min and produced averaged whole-body SARs of 2, 4, or 6 W/kg. Compared to sham exposures, significant alterations of lever responding, reaction time, and earned food pellets occurred during microwave exposure at 4 and 6 W/kg but not at 2 W/kg. There were no differences between radar or SLED pulses in producing behavioral effects.

The allele distribution of two STRs has been investigated in two populations, i.e. Turks (n = 203/200) and Germans (n = 414/402). The Turkish population showed 11 alleles in HumFES/FPS and 6 alleles in HumF13B while the German population had 9 (FES) and 8 (F13B) alleles respectively. Although the frequency profiles looked quite similar in both populations, there exist significant differences mainly due to alleles 8 and 10 (F13B) and allele 12 (FES). Four variant alleles have been sequenced and are described. Investigation of 368 (FES)/372 (F13B) meioses revealed no new mutations.

A system of four short tandem repeat loci (HUMVWF31A, HUMTH01, HUMF13A1, and HUMFES/FPS) has been tested in co-amplification with forensic (post-mortem and post-coital) DNA samples. Semiautomated DNA typing was employed to analyze polymerase chain reaction (PCR) products formed by extension of primers labeled with a fluorescent dye at the 5'-terminus. Most DNA extracts could be typed, although a few required the addition of bovine serum albumin or a pretreatment by ultrafiltration in order to obtain sufficient signal for typing. Balanced signals for the alleles were obtained frequently across the loci, although preferential amplifications of HUMTH01 was observed often with the forensic samples. Band splitting due to nontemplate nucleotide addition to the blunt ends of the amplimers was frequently detected for the DNA extracted from the forensic samples. A data-base was constructed for the African-American population and compared with a Caucasian database. Few differences were observed across the two populations, except at the locus HUMTH01. The fluorescence-based system facilitates large-scale databasing, because the PCR products run off the gel, allowing more than one set of samples to be analyzed per run. Polyacrylamide gel reuse did not diminish genotyping accuracy.

The genetic analysis of ancient populations through DNA from bone remains, requires use of short sized loci that can be amplified by polymerase chain reaction (PCR) for which the short tandem repeat (STR) loci are most suitable. These techniques can also be applied to genetic identification in forensic casework. In this study three STR loci, HUMFES/FPS, HUMTH01, and HUMVWA31A, were selected to estimate their usefulness when applied to recent and ancient spongy bone DNA typing. In addition, loci D1S80 and HLA DQ alpha were also tested in the analysis of recent spongy bone DNA. The recent remains studied were constituted by ten spongy bone samples of postmortem material from one individual buried for 1 year. The ancient remains are composed by 8 spongy bone samples from the heads of left femurs from a XII-XIII Centuries Basque Country population. Adequate amplification and typing results could only be obtained with cetyltrimethyl ammonium bromide (CTAB)-extracted DNA, without any further purification after precipitation. Genotypes of the one year post-mortem material and those of his son and his wife were obtained at the D1S80, HLA-DQ alpha, and STR loci. In all these systems, no exclusion was observed, with a combined probability of paternity of 0.9997. This demonstrates the reliability of the obtained results. The genetic typing of HUMTH01 in spongy bone from the XII-XIII Centuries Basque Country individuals was also performed. This will allow the genetic analysis of ancient bone remains and therefore, to carry out evolutionary population studies.

Human remains identification represents a challenging situation and constitutes a difficult task associated with mass disasters. The only highly efficient means for individual and family group reconstruction is that based on DNA typing. On July 18, 1994 an explosion destroyed the A.M.I.A. (Argentine Israeli Association). Over 100 people died; however, the exact number of victims is still being investigated. Our Service received over 70 remains to be characterized by DNA typing in order to determine the number of victims and to try to reconstruct the family groups to which they belonged. DNA was extracted by a cetyltrimethylammonium bromide (CTAB) based protocol, a rapid molecular screening of all samples was carried out by multiplex STR amplifications including HUMTH01, HUMFABP, HUMHPRTB, HUMRENA4, HUMVWA, HUMFES/FPS and Y27H39LR. Samples with identical genotypes were HaeIII-digested. Southern blotted and probed with YNH-24 (D2S44). PH-30 (D4S139). LH-1 (D5S110) and MS-1 (D1S7) for variable number of tandem repeats (VNTR) evaluation. The minisatellite variant repeat (MVR) approach was used in those cases in which band or profile shift were detected in Southern blot assays. Kinship between victims and putative relatives was initially evaluated by comparison of short tandem repeat (STR) profiles and then confirmed by VNTR with the above probes. The high identification efficiency attained in this case is, in part, supported by a previous experience, the DNA-based molecular characterization of human remains caused by the explosion of the Israeli Embassy in Buenos Aires, March 1992.

The enzyme farnesyl-diphosphate synthase (FPS; EC 2.5.1.1/EC 2.5.1.10) catalyzes the synthesis of farnesyl diphosphate (FPP) from isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). This reaction is considered to be a rate-limiting step in isoprenoid biosynthesis. Southern blot analysis indicates that Arabidopsis thaliana contains at least 2 genes (FPS1 and FPS2) encoding FPS. The FPS1 and FPS2 genes have been cloned and characterized. The two genes have a very similar organization with regard to intron positions and exon sizes and share a high level of sequence similarity, not only in the coding region but also in the intronic sequences. Northern blot analysis showed that FPS1 and FPS2 have a different pattern of expression. FPS1 mRNA accumulates preferentially in roots and inflorescences, whereas FPS2 mRNA is predominantly expressed in inflorescences. The cDNA corresponding to the FPS1 gene was isolated by functional complementation of a mutant yeast strain defective in FPS activity (Delourme, D., Lacroute, F., and Karst, F. (1994) Plant Mol. Biol. 26, 1867-1873). By using a reverse transcription-polymerase chain reaction strategy we have cloned the cDNA corresponding to the FPS2 gene. Analysis of the FPS2 cDNA sequence revealed an open reading frame encoding a protein of 342 amino acid residues with a predicted molecular mass of 39,825 Da. FPS1 and FPS2 isoforms share an overall amino acid identity of 90.6%. Arabidopsis FPS2 was able to rescue the lethal phenotype of an ERG20-disrupted yeast strain. We demonstrate that FPS2 catalyzes the two successive condensations of IPP with both DMAPP and geranyl diphosphate leading to FPP. The significance of the occurrence of different FPS isoforms in plants is discussed in the context of the complex organization of the plant isoprenoid pathway.

We report on a Dutch population study of the STR loci HUMTHO1, HUMFES/FPS, HUMVWA31/1, and HUMF13A1, in which we used multiplex amplification and automated fragment detection. Genotype and allele frequencies showed no deviation from Hardy-Weinberg and linkage equilibrium. The improved Bonferroni procedure was used to combine the results of several tests. The power of discrimination of a complete profile exceeded 0.9998. We compared the allele frequencies in the Dutch sample to the frequencies in other populations using a bipilot to visualize alleles and populations simultaneously. The Dutch sample was similar to most other Caucasian samples. The data demonstrate that the genetic systems in this report are a valuable tool for forensic identity testing in The Netherlands.

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.
