Organizing your talkGeneral principles:1) No more than 1 slide per minute

2) 20% of time on introduction

3) 50% of time on data

4) Save time for summary / acknowledgments

5) Focus on 3 main points

Organizing your talk• Consider your audience:

peers? novices? people you should acknowledge?

•Give intermediate summary points

•Slide transitions

Do your homework!

Organizing your talk

•Practice with colleagues, get advice

•Timing: not too many slides!

•Show data early and often:

people are there to hear your results!

Presenting a manuscript

1) Define the question being asked by the authors2) Indicate its importance3) Provide background4) Evaluate the data:

originalstudy design optimal / adequatematerial and methods clearcredible (controls?)clearly presented

5) Do the results justify the authors conclusions?6) Summarize the new insights arising from the data7) What is the next best question?

Your presentation:

1) 2-3 slides of background information

T-Lymphotropic Viruses

HTLV STLV

Primate T-Lymphotropic Viruses

Human T-Lymphotropic Viruses Simian T-Lymphotropic Viruses

HTLV Genetics

Four Structural and Enzymatic Gene Regions– The gag Region

Gag polypeptides, matrix, capsid, nucleocapsid– The pol Region

Polymerase and reverse transcriptase– The env Region

Envelope glycoproteins– The X Region

tax gene (transcriptional activation of long terminal repeat (LTR) rex gene (expression of structural and enzymatic proteins)

Your presentation:

1) 2-3 slides of background information2) Hypothesis / question

Hypothesis

The authors wished to determine whether previously undescribed HTLVs were present in persons exposed to the blood and body fluids of wild primate populations that were infected with STLV-1 and STLV-3.

Your presentation:

1) 2-3 slides of background information2) Hypothesis / question3) What is to be gained by testing this hypothesis?4) ~1 slide each for key figures

Title should indicate the conclusions from the dataDescribe the methods brieflyCritique the dataSummarize results

5) Summarize the conclusions6) Evaluate / put it into the “big picture”

(defined in your background summary)

Your job as a presenter:

• Engage your audience!• Ask questions (know the answers)

Data justify conclusions?Better way to answer the question?Does data support/refute hypothesis?Health implications?What new ?’s does this raise?Implications for other fields?

NO REASON TO WRITE IN CAPITALS

WRITING IN CAPITALS IS HARD TO READ AND IS VISUAL SHOUTING. THIS MAKES IT DIFFICULT TO UNDERSTAND THE IMPORTANT POINTS (THIS GOES FOR MEMOS AND ANNOUNCMENTS, TOO).

No reason to write in capitals

Writing like this is easier to read and comprehend. This makes it simpler to understand the important points.

Preparing slides

Vary with text, data, drawings, photos

Site Selection & Survey

• 11 rural villages in southern Cameroon proximal to forested and non-forested Non-Human Primate (NHP) habitats

• Study participants completed a survey to determine behaviors that exposed participants to NHPs.

Preparing slides

Use animation, carefully

ELISA Immunoassay

HTLV antibodies bind to p21 envelope (Env) antigen-labeled surface

ELISA Immunoassay

Plate is washed to remove excess antibodies. Only the antibody-antigen

complex remains attached.

ELISA Immunoassay

A fluorescent or chromogenic substrate is attached to the antibody-antigen complex.

ELISA Immunoassay

Plate is washed to remove excess fluorescent or chromogenic substrate.

ELISA Immunoassay

Signal is detected. Intensity of signal is directly correlated with extent of antibody-

antigen complexation.

Preparing slides: summary

•Use animation, carefully

•Simple backgrounds & colors

•Title on each slide

•Make slides especially for the talk

•Spell check

•Vary with text, data, other visuals

Practice, practice, practice!

After the talk

How to answer questions•Respect the intelligence of the questioner

•All questions are interesting

•OK to say you don’t know
