Abstract
In order to increase the power of discrimination, reduce the possibility of adventitious matches, and expand global data sharing, the CODIS Core Loci Working Group made a recommendation to expand the CODIS core loci from the "required" 13 loci to 20 plus three additional "highly recommended" loci. The GlobalFiler(®) Express Kit was designed to incorporate all 20 required and 3 highly recommended loci along with a novel male-specific Y insertion/deletion marker. The GlobalFiler(®) Express Kit allows simultaneous amplification of the following loci: D3S1358, vWA, D16S539, CSF1PO, TPOX, Yindel, AMEL, D8S1179, D21S11, D18S51, DYS391, D2S441, D19S433, TH01, FGA, D22S1045, D5S818, D13S317, D7S820, SE33, D10S1248, D1S1656, D12S391, and D2S1338. The kit enables direct amplification from blood and buccal samples stored on paper or swab and the chemistry features an optimized PCR protocol that yields time to results in less than an hour. Developmental validation testing followed SWGDAM guidelines and demonstrated the quality and robustness of the GlobalFiler(®) Express Kit over a number of variables. The validation results demonstrate that the 24-locus multiplex kit is a robust and reliable identification assay as required for forensic DNA typing and databasing.

Abstract
To assess species specificities among primates of signals from short tandem repeat (STR) loci included in two commercially available kits, mainly the AmpFlSTR Identifiler kit and additionally the GenePrint PowerPlex 16 system, we analyzed 69 DNA samples from 22 nonhuman primate species representing apes, Old World Monkeys (OWMs), New World Monkeys (NWMs), and prosimians. Each prosimian species and the NWM cotton-top tamarin apparently lacked all STR loci probed. Only one peak, the amelogenin-X peak, was evident in samples from all other NWMs, except the owl monkey. In contrast, several loci, including the amelogenin-X peak, was evident in samples from each OWM species. Notably, for each ape sample, the amelogenin peaks were concordant with morphological gender of the individual. Among the primates, especially in apes, the numbers of alleles for STR loci were increasing according to their phylogenetic order: prosimians<NWMs<OWNs<apes, and so among apes: agile gibbons<white handed gibbons<orangutans<gorillas/common chimpanzees/bonobos. The species specificities among primates for a few commercially released multiplex STR kits examined in this study would contribute to forensic examinations.

Abstract
Analysis of length polymorphism at short tandem repeat (STR) loci utilizing multiplex polymerase chain reaction (PCR) remains the primary method for genotyping forensic samples. The AmpFℓSTR(®) Identifiler(®) Plus PCR Amplification Kit is an improved version of the AmpFℓSTR(®) Identifiler(®) PCR Amplification Kit and amplifies the core CODIS loci: D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, CSF1PO, FGA, TH01, TPOX, and vWA. Additional loci amplified in the multiplex reaction are the sex-determinant, amelogenin, and two internationally accepted loci, D2S1338 and D19S433. While the primer sequences and dye configurations were unchanged, the AmpFℓSTR(®) Identifiler(®) Plus PCR Amplification Kit features an enhanced buffer formulation and an optimized PCR cycling protocol that increases sensitivity, provides better tolerance to PCR inhibitors, and improves performance on mixture samples. The AmpFℓSTR(®) Identifiler(®) Plus PCR Amplification Kit has been validated according to the FBI/National Standards and Scientific Working Group on DNA Analysis Methods (SWGDAM) guidelines. The validation results support the use of the AmpFℓSTR(®) Identifiler(®) Plus PCR Amplification Kit for human identity and parentage testing.

Abstract
The AmpFℓSTR(®) Identifiler(®) Direct PCR Amplification Kit is a new short tandem repeat multiplex assay optimized to allow the direct amplification of single-source blood and buccal samples on FTA(®) card without the need for sample purification and quantification. This multiplex assay has been validated according to the FBI/National Standards and SWGDAM guidelines. Validation results revealed that slight variations in primer concentration, master mix component concentration, and thermal cycling parameters did not affect the performance of the chemistry. The assay's sensitivity was demonstrated by amplifying known amounts of white blood cells spotted onto FTA(®) cards, and the assay's specificity was verified by establishing minimal cross-reactivity with nonhuman DNA. No effect on the age of the sample stored on the FTA(®) substrate was observed and full concordance was established in the population study. These findings of the validation study support the use of the Identifiler(®) Direct Kit for forensic standards and database samples genotyping.

Abstract
To investigate the mechanisms of human T-cell reconstitution following allogeneic hemopoietic stem cell transplantation (alloSCT), we analyzed the clonal composition of human cytomegalovirus (HCMV)-specific or Epstein-Barr virus (EBV)-specific CD8+ T cells in 10 alloSC transplant recipients and their donors. All virus-specific CD8+ T-cell clones isolated from recipients after alloSCT contained DNA of donor origin. In all 6 D+/R+ sibling alloSCTs from seropositive donors into seropositive recipients, donor virus-specific clones transferred in the allograft underwent early expansion and were maintained long term in the recipient. In contrast, in 2 of 3 HCMV D+/R- alloSC transplant recipients in whom there was no detectable HCMV infection, donor HCMV-specific clones were undetectable, whereas donor EBV-specific clones were maintained in the same EBV-seropositive recipients, suggesting that transferred clones require antigen for their maintenance. Following D-/R+ transplantation from 3 seronegative donors into seropositive recipients, a delayed primary virus-specific CD8+ T-cell response was observed, in which the T cells contained donor DNA, suggesting that new antigen-specific T cells arose in the recipient from donor-derived progenitors. In 2 of 4 HCMV D+/R+ sibling allograft recipients the clonal composition underwent diversification as compared with their donors, with delayed persistent expansion of HCMV-specific clones that were undetectable in the donor or in the recipient during the early months after transplantation; this diversification may represent expansion of new clones generated from donor-derived progenitors. We conclude that, following alloSCT, late diversification of the HCMV-specific CD8+ T-cell clonal repertoire can occur in response to persistent viral antigen.

Abstract
The use of teeth as an important resource in the analysis of forensic case history by polymerase chain reaction (PCR) or other related methods has been reported. However, a major drawback in using teeth has been that the DNA is present only in trace amounts, and the methods to recover DNA from the flinty material have not been efficient or cost effective. In this report, we describe a method to prepare DNA from the hard tooth tissues. Our studies show that ultrasonication of teeth samples yields sufficient amounts of good quality DNA useful for PCR-based diagnostic methods. The teeth could serve as a reliable source of DNA for amplification-based forensic methods in sex determination. DNA could be obtained from any tooth, regardless of the age of subject. Furthermore, by using the AMEL gene-based primers in PCR, we have shown that the AMEL gene serves as a good marker for sex determination in the Indian population. In our study, the PCR-based method was sensitive and proved to be successful for sex determination with a complete specificity.
