📊 Quiz Overview

🎤 90-Second Elevator Pitch — Practice Daily

"We started with a clinical paradox: some patients develop severe heart failure after low doses of anthracyclines, while others tolerate much higher cumulative doses with no cardiac injury. We hypothesized this reflects constitutional vulnerability rather than treatment effects. Using patient-derived iPSC cardiomyocytes and 3D engineered heart tissues, we found that cardiotoxic patients harbor pre-existing mitochondrial genome instability — with an insertion-biased mutation pattern (~77% in TOX vs ~54% in RES) — and inadequate antioxidant defenses (GPX1, GSTM1), creating a constitutionally vulnerable cardiac phenotype. This shifts the paradigm from 'how much drug causes heart failure' to 'who is already positioned close to cardiac failure thresholds.' The clinical implication is a biomarker-guided, personalized cardioprotection strategy before treatment begins."

22-Day Study Plan

April 28 – May 19, 2026 · 4 hours/day · ADHD-optimized (Pomodoro 25+5)

🧠 ADHD Schedule: Split 4 hours into two 2-hour blocks (morning + afternoon). Each block = 2 × Pomodoro (25min focus + 5min break) + 30min active recall quiz. Never study the same topic for more than 50 minutes continuously.

👥 Opposition Committee

Defense order · May 21, 2026 · Know every member's lens, their papers, their questions

Key tactic: Before the defense, find one sentence in each member's recent paper to reference directly. This single move transforms cross-examination into scientific conversation.

The Three Laws of Defense Answers

1

Acknowledge Before Defending

"That is an important limitation. We addressed it by…" — Never be defensive. Show scientific maturity.

2

Data Before Opinion

Ground every answer in your actual figures and statistics before making interpretive claims.

3

Offer the Future

For every limitation, propose the experiment that would resolve it. This signals you are a scientist, not just a student.
