Make a ppt on peptic ulcer disease for undergraduate medical students (mbbs) in India from Bailey and love Ot should not have more than 25 slides and end in one hour it should also have case based discussion at the first and last and pictures related to each slide it should be interactive and should have lot of flow chart and each slide should have not more than 10 points and each point should not have more than 10 words I will also provide with a checklist of peer review and it should have heading and subheadings accordingly

Peer Review Checklist alignment (from your Ramaiah form):
- Interest arousal - Opening case vignette (Slide 3) with 4 interactive questions
- Objectives stated - Slide 2 with structured 60-min timeline
- Logical sequence - Basic → Pathophysiology → Clinical → Management → Complications → Surgery
- Relevant content - Sourced directly from Bailey & Love 28th Ed. with page citations
- Examples to illustrate - 2 cases (opening + closing) + real endoscopy/X-ray images
- Non-verbal/eye contact - Interactive MCQs + group discussion prompts built in
- Questions facilitated - 4 MCQs + 4 discussion questions per case
- Audio-visual aids - 3 real textbook images + 6 flowcharts + comparison tables
- Summary at end - Slide 25 with 10 key messages + checklist
- Handout - The PPT itself serves as handout
Can u make the slide template white background and only two colour tone

Here's exactly what changed with the new two-tone design:
Design system — Navy Blue (#0D2B4E) + White (#FFFFFF) only:
| Element | Treatment |
|---|---|
| All slide backgrounds | Pure white |
| Headers / title bars | Solid navy |
| Primary content boxes | Navy (white text) |
| Secondary / alternating rows | Very pale navy tint (#E8EEF5) |
| Outline boxes (for contrast) | White fill, navy border + navy text |
| All body text | Near-black on white, navy on tint |
| Accent lines / dividers | Pale navy tint |
| Footer bars | Navy |
| Arrows (flowcharts) | Navy |
Every coloured element from the previous version (orange, teal, red, purple, green) has been replaced with either solid navy or the pale navy tint — keeping perfect two-tone consistency throughout all 25 slides.
the ppt u hared has the peer review points which shouldnt not mention in ppt but the ppt should follow the peer riew checklist the headings should be 32 size subheading 28 and body teext 24 and dont need to add references in all the slides can u correct it and give me the new slides

Your corrected presentation is ready:
PUD v3 Final
Presentation · PPTX
Here is a summary of every correction made:
Font sizes fixed throughout:
- Slide heading (navy header bar) — 32 pt
- Subheadings inside slides (section labels, box titles) — 28 pt
- All body text, bullet points, table content — 24 pt
Peer review checklist removed from slides:
- The entire "Peer Review Alignment" checklist block on the old Slide 25 is gone
- No mention of "peer review", evaluation criteria, or checklist items appears anywhere
- The PPT still follows all 17 checklist criteria silently (interest arousal via opening case, stated objectives, logical sequence, examples, audio-visual aids, Q&A prompts, summary)
References cleaned up:
- Removed per-slide source footers ("Source: Bailey & Love...") from all slides
- Each slide now has only a slim footer showing:
Peptic Ulcer Disease | Dept of Surgery | X/25 - One clean reference appears only on Slide 25 (Summary) — appropriate placement
Slide 25 revised to have 10 key messages + a quick revision Q&A box for students — no checklist.
