▫ Review posters in 9 groups of 5 people; focussing on different
elements of the posters around the room (15-20min)
 Identify 3-4 key issues with respect to the element in question
▫ Short group presentation (2-3 minutes per group)
• Talk (45-50mins)
▫
▫
▫
▫
Review communication modes in science
Advantages and disadvantages of posters
Features of a good poster
Tips and hints
• Questions
Look at posters critically and consider one of
these elements:
• Impact
Is the poster eye-catching?
• Title
Short, punchy, informative?
• Author
Is it clear who the presenter is?
• Layout
Is it tidy? Is the sequence easy to follow
• Readability
Are print size, font etc. appropriate?
• Purpose
Is introduction informative to all readers?
• Conclusions
Are Aims clearly stated?
• Methods
Are these appropriately presented?
• Results
Have table, graphs and figures been used well?
Is it easy for the reader to understand data?
• Practicalities
Is the size good can you read it all, is fixing it OK?
Modes of Communication in Science
• Written (i.e. paper / article) – good for detail; time to digest;
possible to include complex material
Clear beginning, middle and end; Reader can combine with
other sources of information to clarify anything that is not clear.
• Oral/Spoken/Verbal – good for explaining; can get feedback
from listener(s)
Limited attention span but possible to repeat or explain
technical jargon appropriate to audience.
• Visual/Poster – initial impact; memorable image
Little or no personal contact; limited viewing time; competing
for attention.
When are posters used?
• Meetings/Conferences
▫ General, Specialist, Clinical
▫ Large, Small
▫ National, International
• Open days
▫ Entertaining fundraisers
▫ Attracting staff, students
▫ Informing general public
• Site Visits / Visits from Funding Bodies
• Corridor decoration
• Coursework
Pros and Cons of the Spoken Presentation

Poster Sessions
What is in it for the viewer?
• Can be selective
• Opportunity to meet presenter
- ask detailed questions
- ask simple questions
- chance to mention your own interests
• Can eavesdrop / join in discussions
• Time to think about content
• Can take notes, get methods, references
A good poster will rapidly allow the
reader to answer the questions:
• What is this about?
• What are they doing?
• What is the bottom line ?
Title, picture(s)
Aims
Conclusion
• How did they do it?
• Who are these guys?

▫ Use bullet points
Title
• Possibly the most important aspect of the poster.
• First thing viewers will read.
• Short but needs to capture the essence of the poster
• Choose your wording carefully and remember that
the more words you have, the more space they will
take up.

Poster Layout
• Landscape better than portrait
3 columns – reduces line length
Know your audience
• Expert, semi-expert, patients, fund-raisers,
general public
• THINK about content, text and terminology
▫ Avoid acronyms – even ones that seems obvious
to you
▫ No jargon / Do not assume knowledge
▫ Always ask yourself - do they need to know this
piece of information in order to understand my
message?
Tables – keep them simple!

Figure 2. Percentage of positive nuclei scored in patients with recurrent IGH@ translocations.
When comparing the percentages of positive nuclei observed in patients with recurrent IGH@
translocations (known or unknown partner genes), the involvement of certain partner genes was
present in the majority of cells: BCL2, CEBPA, CEBPB and CRLF2. Together patients with
involvement of these genes had a median translocation population of 79%. This was reduced in
patients with ID4 involvement to 65% and further reduced to 30% in patients with IGH@CEBPE. Patients with IGH@-CEBPD translocations tended to have a wind range of
translocation positive nuclei with some as low as 21% and one at 100%.
Boxes denote the range of positive nuclei scored, with extending thin black lines marking
outliers. The thick black line within the boxes denotes the median percentage of positive nuclei
scored per partner gene.

IL-18 and Immune Responses to Periodontal Pathogens

Aims
Introduction
The latest UK Dental Health Survey revealed that 40-45% of adults
have moderate destructive periodontal disease, with 5-10% of
cases being severe. Periodontal disease is a result of excessive
immune responses to dental plaque bacteria which destroy the
supporting tissues of the teeth, leading to loss of dental function.
A novel ELISA was developed to detect IL-18 BPa. Anti-IL-18
BPa was added to the supernatants of P. gingivalis stimulated
cells to investigate the effect on IL-18 concentration.
The addition of anti-IL-18 BPa significantly (P <0.05) increased the
concentration of IL-18 assayed by the ELISA (Figure 4).

Clinical signs of destructive periodontal disease
Cytokines play a central role in inflammatory processes that
influence the progression of periodontal disease and its clinical
outcome. Interleukins (IL) are a group of cytokines produced
primarily by leukocytes. IL-18 has pro-inflammatory properties. It
induces production of interferon (IFN)-γ which has a major role in
the activation of cells of the immune system. IL-18 binding protein
(BPa) strictly controls IL-18 activity by blocking binding to the IL-18
receptor on target cells and IL-18 BPa expression is stimulated by
IFN-γ. This is an important regulatory circuit as overproduction of
IFN-γ causes tissue pathology. However, there is no information on
IL-18 in the pathogenesis of this disease.

IL-18BPa (620nm)
Cells from the pro-monocyte cell line THP-1 were treated with
Vitamin D3 (0.1 μM) to induce differentiation into monocytes.
Differentiation was confirmed by the ability of the cells to adhere to
the plastic plate. THP-1 monocytes were cultured with
lipopolysaccharide (LPS) from the periodontal bacterium P. gingivalis
and the enterobacterium E. coli for 6 and 24 hours. The
concentration of protein in each sample was determined by a protein
assay and IL-18 concentrations were measured using an ELISA
assay kit and detected via a Western Blot.
Conclusions

Methods
The results indicate that significant concentrations of IL-18 and IL18BPa are produced by human THP-1 cells within 6 hours of initial
exposure to P. gingivalis LPS. Antibodies to IL-18BPa increased
the amount of free IL-18 in LPS-stimulated THP-1 cultures
indicating that IL-18BPa normally binds IL-18 secreted from THP-1
monocytes. The balance between IL-18 and IL-18 BPa may be
important in regulating IL-18 activity and may play a role in the
host response to plaque bacteria, and possibly progression and
severity of periodontal disease. This work also indicates that
antibodies or binding proteins could be used to modify immune
responses involving cytokines and therefore be used
therapeutically in the treatment of periodontal disease.

time by a single individual.
