Imposed Constraints On The Smith-Waterman Alignment Algorithm For Enhanced Modeling Of A Single-Molecule Dna Sequencer, Patrick G. Humphrey, Gregory R. Bashford Jan 2005

Imposed Constraints On The Smith-Waterman Alignment Algorithm For Enhanced Modeling Of A Single-Molecule Dna Sequencer, Patrick G. Humphrey, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

An effort has been underway to develop a system for de novo sequencing of single DNA molecules with very long reads. The system operates by optically detecting the passage of fluorescently tagged DNA bases through a detection zone. A successful system would be revolutionary with respect to speed, read length, cost and minimized laboratory infrastructure. An important part of system development is modeling of the detection process. In particular, predicting the expected error from a set of sequencing parameters is helpful in system design. This paper describes variations on the Smith-Waterman algorithm for subsequence alignment used in a single-molecule detection …

Quality Control During Aminoacyl-Trna Synthesis, M. Praetorius-Ibba, S. Ataide, C. Hausmann, J. Levengood, J. Ling, S. Wang, H. Roy, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The fidelity of translation is determined at two major points: the accuracy of aminoacyl-tRNA selection by the ribosomes and synthesis of cognate amino acid/tRNA pairs by aminoacyl-tRNA synthetases (aaRSs) in the course of the aminoacylation reaction. The most important point in aminoacylation is the accurate recognition of cognate substrates coupled with discrimination of non-cognates. While this is generally accomplished by a single enzyme, we have recently found that discrimination against lysine analogues requires the existence of two unrelated lysyl-tRNA synthetases. For other amino acids, initial recognition is not sufficiently accurate with errors being corrected by an intrinsic editing activity. Recent …

Periplasm Organization In Treponema Denticola As Studied By Cryo-Electron Tomography, Jacques Izard, C.-E. Hsieh, C. A. Mannella, Ronald J. Limberger, M. Marko

Department of Food Science and Technology: Faculty Publications

As a spirochete, the genus Treponema is one of the few major bacterial groups whose natural phylogenic relationships are evident at the level of gross phenotypic characteristics such as their morphology. Treponema spp. are highly invasive due to their unique motility in dense media, and their ability to penetrate cell layers. This feature is associated with the helical cell body and the presence of flagellar filaments in the periplasm. Treponema denticola is an oral pathogen involved in endodontic infections and periodontal diseases. The presence and quantity of T. denticola in the subgingival biofilm is correlated with the severity of periodontal …

Combining Cytotoxic And Immune-Mediated Gene Therapy To Treat Brain Tumors, James Curtin, Gwendalyn King, Marianela Candolfi, Remy Greeno, Kurt Kroeger, Pedro Lowenstein, Maria Castro

Articles

Glioblastoma (GBM) is a type of intracranial brain tumor, for which there is no cure. In spite of advances in surgery, chemotherapy and radiotherapy, patients die within a year of diagnosis. Therefore, there is a critical need to develop novel therapeutic approaches for this disease. Gene therapy, which is the use of genes or other nucleic acids as drugs, is a powerful new treatment strategy which can be developed to treat GBM. Several treatment modalities are amenable for gene therapy implementation, e.g. conditional cytotoxic approaches, targeted delivery of toxins into the tumor mass, immune stimulatory strategies, and these will all …

Using Incomplete Citation Data For Medline Results Ranking, Jorge R Herskovic, Elmer V Bernstam Jan 2005

Using Incomplete Citation Data For Medline Results Ranking, Jorge R Herskovic, Elmer V Bernstam

Faculty, Staff and Student Publications

Information overload is a significant problem for modern medicine. Searching MEDLINE for common topics often retrieves more relevant documents than users can review. Therefore, we must identify documents that are not only relevant, but also important. Our system ranks articles using citation counts and the PageRank algorithm, incorporating data from the Science Citation Index. However, citation data is usually incomplete. Therefore, we explore the relationship between the quantity of citation information available to the system and the quality of the result ranking. Specifically, we test the ability of citation count and PageRank to identify "important articles" as defined by experts …

Effects Of Heavy Metal Accumulation On The 96-H Lc_50 Values In Tench Tinca Tinca L., 1758, Syed Lal Shah, Ahmet Altindağ

Turkish Journal of Veterinary & Animal Sciences

The effects of already accumulated heavy metals (Hg, Cd, Pb) in the body of tench on the 96-h LC_50 values of the respective heavy metals were studied. The body concentration of mercury, cadmium and lead was 0.011, 0.32 and 1.59 mg/g respectively, and their 96-h LC_50 values were 1.0, 6.5 and 300.0, ppm, respectively. The general accumulation order of heavy metals and their respective 96-h LC_50 values were Hg< Cd< Pb. It was observed that the fish with lowest body concentration of heavy metal showed the lowest 96-h LC_50 value of the respective heavy metal and vice versa. This close relationship showed that the previous body accumulation of heavy metals has a direct effect on the 96-h LC_50 values of the respective heavy metals and the susceptibility of fish.

Investigation Of The Selectivity Parameters For Carp (Cyprinus Carpio Linnaeus, 1758) In Seyhan Dam Lake, Caner Enver Özyurt, Dursun Avşar

Turkish Journal of Veterinary & Animal Sciences

Selectivity studies are very important for sustainable fisheries. Therefore, in this study, selectivity parameters for the carp in Seyhan Dam Lake were estimated using gill nets having a mesh size of 28, 32, 40 and 45 mm. Gill nets used in pikeperch fishing of mesh size of 28, 30 and 32 mm could cause growth in the overfishing of carp. Therefore, it is recommended that longline fishing should be commonly used instead of gill nets on pikeperch fishing. Consequently gill nets having minimum 50 mm mesh size can be used for carp fishing in Seyhan Dam Lake.
