Funding for this work was provided by the following sources: The Official Regional Delegation shall consist of two hundred sixteen participants. Planktonic cell density showed a very small but statistically significant reduction in the strain containing the p nspC plasmid. Digital cameras point and shoot only with a maximum of These genes are found on the V.

2012 National Schools Press Conference (NSPC)
Cells were lysed by sonication, cell debris was removed by centrifugation, and cellular protein was precipitated by addition of trichloroacetic acid.
The objective of the competition is to recognize the Ten 10 Outstanding School Papers across the seventeen 17 regions in the country that showcase the collaborative competence of the schools' editorial staff and their school paper advisers' critical role in developing and producing quality school papers.
One possible interaction could involve an autocrine-type signaling mechanism where a modified form of norspermidine is secreted by V. The presentation shall be evaluated according to the following journalistic skills: The promise and peril of transcriptional profiling in biofilm communities. Finding gene-expression patterns in bacterial biofilms. The delegates are expected to be at the venue before dinner on April 8, Sunday and to leave after breakfast on April 13,Friday.
For Western blotting, the serum and the HRP-conjugated goat anti-rabbit secondary antibody were used at a 1: Kaya lng di ako pinalad this year sa regionals namin eh Effect of nspC overexpression on NspC levels, biofilms, vps gene transcription, and motility A. Norspermidine concentrations in the cells do not change in response to increased NspC levels.
National Schools Press Conference (NSPC) - Schools / Universities
To determine if vps gene transcription was also affected by increased NspC levels, we measured the activity of the vpsL promoter making use of a vpsL-lacZ chromosomal fusion in this strain. The distinction between these two possibilities will require more in depth studies of these pathways.
Error bars show standard deviations of six replicates.
Uses appropriate grammar, spelling, capitalization and punctuation. Npc bars show standard deviations of three biological replicates. Please refer to Enclosure No. It is possible that increased numbers of NspC protein can sequester free spermidine in the cell, leading to an increase in biofilm formation. Planktonic cell density showed a very small but statistically significant reduction in the strain containing the p nspC plasmid.
Chooses tone and style to fit subject. Norspermidine is synthesized by decarboxylation of carboxynorspermidine by the enzyme carboxynorspermidine decarboxylase encoded by the nspC gene Lee, et al.

DSLR and other high-end digital cameras shall not be allowed in order to level the playing field. Uses appropriate photos, illustrations and graphics. We then assayed the effect of elevated NspC levels on various aspects of V.
Funding for 212 work was provided by the following sources: National Center for Biotechnology InformationU. Results High levels of NspC enhances growth, biofilm formation and vps gene transcription; decreases motility Deletion of the nspC gene has been shown to be deleterious to biofilm formation in V.
Environmental nsppc of Vibrio cholerae. Cloning of the nspC gene The nspC gene was amplified from chromosomal DNA using primers that annealed 40bp upstream and bp downstream of the coding sequence.
Abstract Biofilm formation in Vibrio cholerae is in part regulated by norspermidine, a polyamine synthesized by the enzyme carboxynorspermidine decarboxylase NspC. Copy Reading and Headline Writing 7. Extraction, benzoylation, and detection of polyamines Extraction of polyamines from shaking cultures were performed as previously described McGinnis, et al.
We next hypothesized that cells could indeed produce increased amounts of norspermidine as a result of increased NspC levels; however, the excess norspermidine might be exported to maintain norspermidine homeostasis in the cell. Schools have the option to submit electronic or printed copies of their entries.
Therefore, product feedback inhibition could contribute to maintaining norspermidine levels and partially account for the lack of an increase in cellular norspermidine levels in the nspC overexpression strain.
