COMMUNITY ANALYSIS OF A UNIQUE FULL-SCALE WASTEWATER TREATMENT PLANT AS REVEALED BY 454-PYROSEQUENCING
… to help improve the microbial populations. 454-pyrosequencing was used as a method to identify and analyze the microbial populations of this glycerin enriched activated sludge wastewater treatment plant. The objectives of this research were to 1) determine the differences between LANL SWWS …

De novo sequencing, assembly and analysis of the genome and transcriptome of the nematode Panagrolaimus superbus
… of P. superbus was sequenced using the 454 (Roche) platform. To enrich for stress-related genes, nema- todes were exposed to one of the following stresses (desiccation, cold, heat or oxidation). Equal numbers of nematodes from each stress treatment were combined with unstressed control …

Diversity and spatial distribution of fungal endophytes in a Eucalyptus grandis tree
… bar-coding, or metagenetics, was done using 454-pyrosequencing parallel sequencing of the barcode amplicons of all the fungal isolates present in the plants from the total DNA of the plant. Secondly, conventional DNA bar-coding of was done of fungal endophyte isolates. Isolates of the …

MEASUREMENT OF BRANCHING FRACTIONS OF B DECAYS TO K_1(1270) PI AND K_1(1400) PI AND DETERMINATION OF THE CKM ANGLE ALPHA FROM B0 --> A_1(1260)+/- PI-/+
… National Accelerator Laboratory, correspond to 454 million B Bbar pairs produced in e+ e- annihilation. We use the results to estimate the weak phase alpha from the time dependent CP asymmetries in B0 --> a_1(1260)+/- pi-/+ decays.

Deciphering the role of BRCA2 at the damage-induced G2 checkpoint
… regions that span BRCA2 amino acids (aa) 1-454 and aa 2438-2824. My research has focused on understanding how these two regions contribute to G2 checkpoint function through the interrogation of two novel interactions of BRCA2 mediated at these regions. My experiments have identified that …

The development and optimization of a hydrogen-fueled internal combustion engine
… approach. This effort starts with a conventional 454 cubic inch Chevrolet V-8 engine that is then modified in various ways to accommodate the use of hydrogen; including specially formed intake and exhaust passages, modified cam, and fuel injection. Because the application is for constant speed …

Development of new tools and applications for high-throughput sequencing of microbiomes in environmental or clinical samples
… conventional longer-read systems like the Roche-454 GS FLX pyrosequencing instrument. Short-read platforms, however, are not readily amenable to some applications like metagenomics and metatranscriptomics, and therefore pyrosequencing remains the dominant sequencing technique in these fields. The …

The impact of chlortetracycline on Drosophila melanogaster and Aedes aegypti
… 50 µg ml-1 and above. Culturable techniques and 454 pyrosequencing, demonstrated that the microbial diversity of Drosophila was predominantly Acetobacter. Bacterial elimination through egg dechorionation yielded some similar results to chlortetracycline treatment. However, fecundity and life-span …

Probabilistic arithmetic automata : applications of a stochastic computational framework in biological sequence analysis
… high throughput sequencing technologies such as 454 or Solexa/Illumina. Viewing biological sequences, such as DNA and proteins, as strings allows their investigation under a generative random string model. That is to say, one can define a probabilistic null model that generates random strings as …

Characterization of chalcone synthase genes in red raspberry cultivar (rubus idaeus)
… (Rubus idaeus) cv. Glen Moy (SCRI), using 454 sequencing technology assisted by a systematic construction of fosmid libraries. The two BACs (29M05 and 24B12) always presented similarities in almost analyses resulting from the presence of a 53 kb overlap that was revealed by assemblies of …

Outcomes of renal transplantation in patients with lupus nephritis: a single centre study in Cape Town
… 2004 to 31st December 2013. Results: There were 454 patients who were transplanted in the study period of which 15/454 (3.3%) had LN. The M:F ratio of LN patients was 1:14, mean age was 25±10 years, all were known with class- IV LN and 10/15 (66.7%) received graft from a cadaveric donor. …

The burden of human coronavirus infection in children hospitalized with severe lower respiratory tract infection in Cape Town, South Africa (2012-2013)
… due to sample loss prior to analysis, leaving 454 available for analysis. A total of 42 (9.1%, 95% CI 6.7- 12.1%) participants tested positive for HCoV in at least one of the two specimens. PCR was able to detect a total of 35 (7.7%) cases from the 454 tested IS specimens compared to 23 (5.0%) …

Using emergent self-organizing maps to identify marine group II archaea genomic fragments from uncharacterized microbial metagenomic sequences
… homology. Fosmids were sequenced using a single 454- titanium sequencing run, and contigs subsequently assembled in silico. A total of 99 contigs over 20kb were retrieved, at least 72 of which belong to the marine group II archaea. The phylogenetic substructure of the marine group II archaeal …
