The document provides 70 multiple choice questions to improve haematology skills.

Brg1 is crucial for keeping hair follicle stem cells and repairing skin, working with the Sonic Hedgehog pathway to promote hair growth.

Neurosteroids change how GABA_A receptors work in the brain, which could be important for treating temporal lobe epilepsy.

Proper control of β-catenin activity is crucial for development and preventing diseases like cancer.

Antiandrogens and androgen inhibitors like spironolactone, finasteride, and dutasteride can treat hair loss and skin conditions, but they have risks and side effects, including potential harm to pregnant women and risks of cancer and heart issues. Herbal remedies also have antiandrogenic effects but lack safety validation.
