Presentation Transcript

  1. Writing the Poster Text:Every Word Counts APS Professional Skills Course: Making Scientific Presentations: Critical First Skills

  2. Why a Poster vs. Talk • Reach more people both in and out of your field • More in-depth discussion of your work • More efficient because people can read about your work during the time the poster is available, whether you are there or not • Less stressful

  3. Difference Between Oral and Poster Presentations Speaking to a few people at a time Speaking before a large crowd of people

  4. Why You Need a Great Poster

  5. Writing the Poster • Decide on one essential concept you would like to get across • Know your audience • Should be easy to follow what you did and why you did it, even if you are not present • Succinct in wording • Figures easily understandable • Conclusions follow from data presented

  6. Remember • Start early • Set deadlines • Plan for set backs • Allow additional time for • Editing • Proofreading • Printing problems

  7. Title (from Abstract) Background and Introduction Methods Results Summary Conclusion Contact Information Check meeting guidelines - may or may not include Abstract Literature Cited Acknowledgements Organizing the Content

  8. Poster Title • Already written • Use same title as submitted in Abstract Kidney-Specific Enhancement of Angiotensin II Stimulates Endogenous Intrarenal Angiotensinogen and Initiates Renal Injury in Gene-Targeted Mice

  9. Background and Introduction • Hypothesis • Relevant question you are trying to answer • State as hypothesis • Minimum of background information and definitions to provide context • Description and justification of general experimental approach

  10. Background and Introduction • Use inverted triangle model • Include photos if appropriate • Make it easy to read quickly • Short blocks of text • Use bullet points if possible • 200 words maximum Big Picture Current State of Knowledge Hypothesis

  11. Introduction Example • We recently reported that concomitant increases in proximal tubular angiotensinogen (AGT) mRNA and protein participate in increased intrarenal angiotensin (Ang) II leading to progressive development of hypertension and renal injury in Ang II-infused rats.

  12. Introduction Example Cont’d • However, it has not been established if selective increases in intrarenal Ang II can be responsible for the stimulation of intrarenal AGT, development of progressive hypertension, and/or renal injury.

  13. Introduction Example Cont’d Objective Using a transgenic mouse model in which human AGT is expressed only in the kidney, these experiments were performed to determine if selective renal overproduction of Ang II elicited by stimulating human AGT present only in the kidney in the presence of human renin will cause increases in endogenous mouse AGT mRNA and protein expression in kidneys leading to slowly progressive hypertension and renal injury.

  14. Methods • Experimental design • Flow charts work well • Model system (if applicable) • If using animals/humans, include IACUC/IRB approvals • Name methods rather than give details • e.g., Northern blot • Statistical methods used • 200 words maximum

  15. Methods Example • We used 3 groups of mice: 1. Single transgenic mice (A, N=14) expressing human AGT only in the kidney regulated by kidney-specific androgen regulated protein promoter 2. Double transgenic mice (D, N=13) expressing human renin systemically in addition to human AGT only in the kidney 3. Wild type (W, N=12) of genetic background C57BL/6J mice

  16. Methods Example cont’d • Exogenous human AGT protein is inactive in single transgenic mice because endogenous mouse renin cannot cleave human AGT to Ang I due to a high species-specificity. • All mice were monitored from 12 to 18 wks of age with free access to a regular diet and water.

  17. Methods Example Cont’d Measurements 1. Systolic blood pressure: Tail cuff method 2. Human and mouse AGT mRNA in kidney and liver: Real time RT-PCR 3. Human and mouse AGT protein in kidney: Western blot analysis 4. Plasma and kidney Ang II: SPE/RIA 5. Renal injury: a) Interstitial collagen-positive area: PicroSirius Red stain b) Interstitial macrophage infiltration: CD68-positive cell number c) Thickness of afferent arteriolar wall: IHC of αSMA plus elastin stain

  18. Results • Focal point of poster • Enough information needed to support interpretation of the results • A story should unfold as you move from figure to figure • Group together data that are related • Use data that are directly related to the hypothesis • May not necessarily describe all results from study

  19. Results • Say whether or not the experiment worked • Follow with qualitative and descriptive results • Follow with presentation of data analysis • Figures and tables (figures are best) • Each figure should be able to stand alone • Clear title • Axes well labeled • 200 words maximum

  20. Results Example

  21. Results Example Cont’d

  22. Summary (of Results) • Not just a repeat of the Abstract • Bullet point list of key findings • May be first thing people read • Need to grab attention of the reader • State whether hypothesis was supported • Relevance of findings • 250 words maximum

  23. Conclusion • Emphasize single most important point • Make sure conclusion addresses the hypothesis • If you have more than one question, need to have more than one answer • Very brief: 50 words maximum

  24. Summary/Conclusion Example • These data indicate that the selective renal overproduction of Ang II stimulates endogenous intrarenal mouse AGT mRNA and protein expression which may contribute to the slowly progressive hypertension and renal injury in the gene targeted mice even before the development of marked hypertension. • Locally generated Ang II may play important roles in the development of renal injury.

  30. Further Information • Your contact information • Include your email address • Lab’s web page (if applicable) • 20 words maximum

  31. Tips for Writing a Good Poster • Edit your text several times • Aim for 800 words maximum • Can you answer “Yes” to these questions? • Is only one main concept included? • Can your logic be followed without you explaining it? • Are the graphics self-explanatory? • Is there an explicit take-home message? • Did you and someone else proofread your text?

  32. Ready to Move On • If you answered “Yes” to all those question AND • Your collaborators (co-authors) agree You can move on to designing the poster!
