DiGeorge and Job syndrome – well-defined immunodeficiencies
George syndrome (22q11.2 deletion) and Job syndrome (hyper-IgE) explained with clear clinical signs and immune defects. Learn how these well-defined genetic syndromes cause recurrent infections, immune dysfunction, and characteristic physical findings. This video breaks down DiGeorge syndrome’s pharyngeal pouch failure from chromosome 22 microdeletion—remember “catch 22”—and its CATCH-22 features: cardiac defects, abnormal facies, thymic hypoplasia,…
Epigenetics – An Introduction
This sketch video about epigenetics was created by Armando Hasudungan, in collaboration with Professor Susan Clark and Dr Kate Patterson at the Garvan Institute of Medical Research. It has been created for a broad, non-expert audience to highlight key messages about the role epigenetics plays in biological processes like development and diseases such as cancer.
Hepatitis C virus life cycle – Molecular mechanism
Learn about the Hepatitis C virus, including its structure, transmission, and how it targets the liver to cause chronic infection. This video explains the viral life cycle, immune evasion strategies, and the clinical implications of Hepatitis C infection.
Our mission
Medical science is complex. Understanding it should feel possible.
Armando Hasudungan turns difficult medical science into clear visual explanations and connected learning experiences—so learners can see the whole picture, remember what matters and find a clearer way forward.
See it clearly
Turn abstract processes and invisible relationships into something the learner can picture.
Connect the pieces
Build understanding around how concepts fit together—not a pile of isolated facts.
Make it useful
Help learners move from explanation to recall, revision and the next logical step.
What clarity feels like
When the topic stops being a blur.
Learners do not come back because the subject became easy. They come back because the explanation gave them a picture they could work with.
“Armando's teaching style gives me the foundational knowledge.
Jessica Payne-Burnett
Medical Student, Charles Sturt University
“The notes I make during his videos help me retain everything better.
Ayesha RaiStudent, Islamabad Medical and Dental College
“The drawings are amazing and super easy to remember.

Coming soon: the AH study platform
The explanation is only the start.
The free library helps you find a clear explanation. The AH platform is being built to help you connect the resources, follow a clearer path and check what actually stuck.
- Watch in a focused, ad-free study environment.
- Move between connected videos, notes, diagrams and questions.
- Know what belongs next instead of rebuilding the study path yourself.
- Test your understanding while the topic is still fresh.
New and worth a look
Keep building the picture.
Lambert-Eaton Myasthenic Syndrome
Overview Lambert–Eaton myasthenic syndrome (LEMS) is a rare autoimmune disorder of the presynaptic neuromuscular junction. It causes impaired acetylcholine release, producing the characteristic triad of proximal muscle weakness, reduced reflexes and autonomic dysfunction. LEMS may occur as a paraneoplastic syndrome—most commonly associated with small-cell lung cancer (SCLC)—or as a non-tumour-associated autoimmune disorder. Neuromuscular junction: connection…
