Lesson 2 • Cell Cycle Dysregulation

Analyses checkpoint failures that permit uncontrolled proliferation. Connects cyclin-CDK pathway disruption to therapeutic targeting strategies.

Lesson 3 • Paraneoplastic Syndromes

Identifies remote systemic effects of tumours mediated by hormones, antibodies, or cytokines. Connects tumour biology to multi-organ clinical presentations.

Lesson 4 • Tumour Microenvironment

Describes how tumours remodel surrounding stroma, vasculature, and immune cells. Explains immune evasion and treatment resistance at the tissue level.

Lesson 1 • Ischaemic Heart Disease Mechanisms

Differentiates stable angina, unstable angina, and myocardial infarction by supply-demand mismatch severity. Links coronary pathology to myocyte death patterns.

Lesson 2 • Heart Failure Pathophysiology

Explains systolic and diastolic dysfunction through neurohormonal compensation and decompensation. Connects Frank-Starling mechanics to clinical congestion.

Lesson 3 • Hypertension and Vascular Remodelling

Analyses primary and secondary hypertension mechanisms and end-organ consequences. Links sustained pressure elevation to cardiac, renal, and cerebrovascular damage.

Lesson 4 • Arrhythmia Mechanisms

Covers abnormal automaticity, triggered activity, and re-entry circuits as arrhythmia substrates. Provides electrophysiological basis for rhythm disorder classification.

Lesson 1 • Ventilation-Perfusion Mismatch

Quantifies V/Q ratio extremes from shunt to dead space and their hypoxaemia patterns. Foundational for interpreting arterial blood gas abnormalities.

Lesson 2 • Obstructive Lung Disease Mechanisms

Differentiates asthma, COPD, and bronchiectasis by airflow limitation mechanism. Connects airway inflammation and remodelling to spirometric patterns.

Lesson 3 • Restrictive Lung Disease Mechanisms

Covers intrinsic fibrotic and extrinsic chest wall causes of reduced lung compliance. Links stiffness to diffusion impairment and hypoxaemia.

Lesson 4 • Acute Respiratory Distress Syndrome

Explains diffuse alveolar damage, surfactant loss, and non-cardiogenic oedema in ARDS. Integrates inflammatory and mechanical ventilation injury concepts.

Lesson 1 • Chronic Kidney Disease Progression

Explains hyperfiltration, tubulointerstitial fibrosis, and nephron loss driving CKD progression. Links GFR staging to systemic uraemic complications.

Lesson 2 • Hypertensive and Diabetic Nephropathy

Traces glomerular haemodynamic injury from sustained hypertension and hyperglycaemia to end-stage disease. Integrates cardiovascular and metabolic pathophysiology.

Lesson 3 • Tubular Transport Disorders

Covers renal tubular acidosis types and Fanconi syndrome as models of selective transport failure. Connects tubular dysfunction to systemic electrolyte and acid-base consequences.

Lesson 4 • Glomerular Disease Mechanisms

Distinguishes nephrotic from nephritic syndrome by glomerular injury pattern and protein loss. Links immune complex deposition to filtration barrier disruption.

Lesson 1 • Thyroid Disorder Mechanisms

Covers hypothyroid and hyperthyroid states from autoimmune, structural, and functional causes. Connects thyroid hormone excess or deficiency to metabolic rate and organ effects.

Lesson 2 • Calcium and Bone Metabolism Disorders

Covers PTH, vitamin D, and calcitonin dysregulation causing hypercalcaemia, hypocalcaemia, and metabolic bone disease. Connects endocrine and renal pathophysiology.

Lesson 3 • Diabetes Mellitus Pathophysiology

Differentiates Type 1 autoimmune beta-cell destruction from Type 2 insulin resistance and secretory failure. Links chronic hyperglycaemia to micro- and macrovascular complications.

Lesson 4 • Metabolic Syndrome and Obesity

Explains adipose tissue dysfunction, ectopic lipid deposition, and chronic low-grade inflammation as metabolic syndrome drivers. Integrates cardiovascular and renal risk.

Lesson 1 • Seizure and Epilepsy Pathophysiology

Covers excitatory-inhibitory imbalance, ion channel mutations, and network synchronisation as seizure substrates. Connects focal and generalised mechanisms to seizure classification.

Lesson 2 • Demyelinating Disease Mechanisms

Explains autoimmune and metabolic myelin destruction and its effect on axonal conduction velocity. Connects lesion location to clinical relapse-remission patterns.

Lesson 3 • Cerebrovascular Disease Mechanisms

Differentiates ischaemic and haemorrhagic stroke by vascular mechanism and penumbra dynamics. Connects time-dependent neuronal death to functional deficit patterns.

Lesson 4 • Neurodegenerative Disease Pathology
