Analysis of mixtures using next generation sequencing of mitochondrial DNA hypervariable regions
Aim To apply massively parallel and clonal sequencing
(next generation sequencing or NGS) to the analysis of forensic
mixed samples.
Methods A duplex polymerase chain reaction (PCR) assay
targeting the mitochondrial DNA (mtDNA) hypervariable
regions I/II (HVI/HVII) was developed for NGS analysis on
the Roche 454 GS Junior instrument. Eight sets of multiplex
identifier-tagged 454 fusion primers were used in a combinatorial
approach for amplification and deep sequencing
of up to 64 samples in parallel.
Results This assay was shown to be highly sensitive for
sequencing limited DNA amounts ( ~ 100 mtDNA copies)
and analyzing contrived and biological mixtures with low
level variants ( ~ 1%) as well as “complex” mixtures (≥3 contributors).
PCR artifact “hybrid” sequences generated by
jumping PCR or template switching were observed at a
low level (<2%) in the analysis of mixed samples but could
be eliminated by reducing the PCR cycle number.
Conclusion This study demonstrates the power of NGS
technologies targeting the mtDNA HVI/HVII regions for
analysis of challenging forensic samples, such as mixtures
and specimens with limited DNA
Early childhood lung function is a stronger predictor of adolescent lung function in cystic fibrosis than early Pseudomonas aeruginosa infection
Pseudomonas aeruginosa has been suggested as a major determinant of poor pulmonary outcomes in cystic fibrosis (CF), although other factors play a role. Our objective was to investigate the association of early childhood Pseudomonas infection on differences in lung function in adolescence with CF
Hot Yoga Establishments in Local Communities Serving Pregnant Women: A Pilot Study on the Health Implications of its Practice and Environmental Conditions
Hot yoga establishments have been increasing in popularity in local communities. Studios may support participation among pregnant women though no clinical studies currently exist that examine prenatal hot yoga effects. The pilot study described in this article aimed to assess the spread of prenatal hot yoga and to provide information on the environmental conditions and practices of those who engage in hot yoga within a local community. A thermal environment meter was used to measure ambient air conditions during three 90-minute hot yoga classes. Mothers who practiced prenatal hot yoga were more likely than non-hot yoga practitioners to have someone aside from an obstetrician/gynecologist discuss prenatal exercise safety with them. Prenatal public health education campaigns need to he refined. Public health officials and obstetricians/gynecologists need to he aware that those who engage in a hot yoga practice are more likely to trust someone other than their health care provider or public health professional regarding safety of this practice
DNA sequencing by MALDI-TOF MS using alkali cleavage of RNA/DNA chimeras
Approaches developed for sequencing DNA with detection by mass spectrometry use strategies that deviate from the Sanger-type methods. Procedures demonstrated so far used the sequence specificity of RNA endonucleases, as unfortunately equivalent enzymes for DNA do not exist and therefore require transcription of DNA into RNA prior to fragmentation

In-vessel inspection before head removal: TMI II: Phase I. (Conceptual development)
The objective of the task is to provide for an internal inspection of the reactor vessel and the fuel assemblies prior to reactor vessel head removal. Because the degree of damage to equipment and fuel in the TMI-II reactor is not precisely known, it is important that as much information as possible be obtained on present conditions inside the reactor. This information will serve to benchmark the various analyses already completed or underway and will also guide the development of programs to obtain more information on the TMI-II core damage. In addition, the early look will provide data for planning the reactor disassembly program
