Instructions for Abstracts and Poster Presentations
Deadline: April 9, 2015
"MANDATORY ELECTRONIC SUBMISSION"
How to Prepare your Abstract:
1. Your abstract is limited to 250 words.
2. In addition to title, author and author affiliation, your abstract should be informative, containing: (a) the study's specific objective, unless given by the title; (b) brief statements of methods, if pertinent; (c) a summary of the results; and (d) the conclusions. It is NOT satisfactory to state: "The results will be discussed." An example of abstract elements can be at: Nature 2013 - How to construct a summary abstract (PDF).
3. Use short specific titles. Avoid using superfluous words such as: "preliminary studies on", etc.
4. The recommended font is Times and the font size is large.
5. Each abstract must be reviewed by the preceptor. Then, with mutual agreement between the student and the mentor, THE STUDENT SUBMITS THE ABSTRACT ELECTRONICALLY AT: https://ocrss.louisville.edu/evpri/precis/. (Note: Registration will be available after the first part of January 2015. The deadline for submission is midnight on APRIL 9, 2015.) For the student and mentor to be able to access the system, thy must first "Create A New Account" on the Precis site. In the submission process, the student can work on the abstract and “save and submit later”, returning to the abstract as needed to edit. Once the student “submits” the abstract, it cannot be edited by the student. Upon electronic submission, the student and the mentor will be notified of submission. The mentor must then go into the system and approve the abstract. Only the mentor or administrator can “unsubmit and edit” the abstract. The mentor approval provides assurance of adherence to the guidelines and the validity of the presentation.
6. The presenter's name should be entered first on the abstract. When listing authors from different affiliations, list by author order, with or without reference markers.
7. Remember that your abstract will be used as you submit it; any typographical errors, misspellings, poor hyphenations and deviations from acceptable usage will be reproduced in the abstract book. Also, please include any special symbols, such as Greek letters where necessary and check to make sure they were retained.
8. When using abbreviations for compounds, spell out the compound in full the first time it is mentioned, followed by the abbreviation in parentheses. Do not abbreviate compounds in the title of the abstract.
9. An abstract should be submitted regardless of the format of presentation. Students are encouraged to present a poster or exhibit. If the discipline does not lend itself to these formats an equivalent demonstration of the research will be arranged. Contact Pamela W. Feldhoff, Ph.D.
THE CONSERVED DXD MOTIF IS ESSENTIAL FOR GANGLIOSIDE GM2 SYNTHASE ACTIVITY. J. Li, M.L. Allende, D.S. Darling, C.A.Worth, & W.W. Young, Jr. Departments of Biochemistry & Molecular Biology, and Molecular, Cellular, & Craniofacial Biology.
GM2 synthase produces gangliosides that are functionally important to nervous system maintenance. The DXD motif is highly conserved in 13 families of glycosyltransferases including GM2 synthase. Mutation of the aspartic acid residues of the motif in two glycosyltransferase families markedly reduced enzymatic activity. In human GM2 synthase this motif is 352-VLWVDDDFV. To examine the importance of the DXD motif in GM2 synthase, we prepared a series of mutant DNS constructs by site-directed mutagenesis and stably expressed them in Chinese hamster ovary (CHO) cells. For the D356A and D358A single mutations, the D356A/D358A double mutation, and the D356N/D357N/D358N triple mutation, the overall folding of these mutated enzymes appeared normal as judged by assembly into a homodimer and by Golgi localization. However, their activities were reduced at least 900 fold to background level. In contrast, the activity of GM2 synthase singly mutated at V352A and W354A was greater than wild type and 20% of wild type, respectively. We conclude that V352 is not essential for activity, W354 is required for full activity, and the highly conserved D356 and D358 are critical for GM2 synthase activity. (Supported by GM42698)
Suggestions for the Presentation of an Effective Poster
Posters have become the principal mechanism for the efficient transfer of information at many scientific meetings. However, poster quality is often uneven. The chief reasons for low quality posters are poor planning and inexperience. The information on this sheet should help you improve the effectiveness of your poster presentation.
1. INITIAL PLANNING. Your poster area will be approximately 4' high by 6' wide. You will need a title board or banner that includes the title of your abstract, authors and department(s). Lettering should be about 1" high and can easily be done with computer programs available in most departments. The banner should be at least 4' wide and can be done as soon as your abstract is finished. A copy of your abstract, typed in large type should be posted in the upper left of your display. Time will be saved if the copy of your abstract for the poster is prepared at the same time as the final copy (Electronic Submission due April 8-10, 2014).
2. ROUGH LAYOUT. Meet with your mentor to decide what data will be included and how it will be presented (i.e., Tables or Figures and how much data to include in each). Sketch rough graphs and tables and tape them to a 4' by 6' area on a wall to be sure the information flow to the reader is clear, logical and legible from a distance of 3' to 5'. Consider the use of color to differentiate between several lines in a figure or to emphasize specific information. In a balanced poster, figures and tables cover about half of the display area. Figure legends (do not omit) and any other written material should be succinct. Avoid abbreviations, acronyms and jargon. Resist the temptation to overload your poster. Try to efficiently communicate to the viewer how you got your results and what they mean. Use a consistent large type style throughout. Write a summary list of your conclusions for display on the right side of your poster area.
3. FINAL FORMAT. Each department should have computer programs to draw and appropriately label figures. Work with your mentor or lab associates to learn how to put the data into final form. If possible, use a laser printer for the final copy. For a modular format, inexpensive framing for your data can be made by cutting colored heavy duty poster board 1" larger than your figure. The combined data and frame can then be tacked to the display area or moved around as necessary. Push Pins will be provided. For a PowerPoint printed format, see printing information below. You should decide, in advance, how you will verbally present your studies (in 5-7 minutes) to interested students and faculty. Normally, people will want a couple of minutes to review your poster and information on why the problem is important (Introduction) and how you approached it (Methods). After reviewing the Results and Conclusions, you may want to briefly discuss how your study relates to other work done in the area and the future direction of the project. Be prepared to answer relevant questions (Significance), but don't be surprised if there are some you can't answer or don't fully understand.
