Intiation and promotion. The neoplastic cell. Tumor progression. Tumor angiogenesis.
Pathophysiology of tissue injury and repair. The response to tissue injury. Hemostasis: Phases and mechanisms; Hemorrhagic diseases due do defects in primary or secondary hemostasis; Consumption coagulopathies. Thrombosis, embolism, infarction. Acute and chronic inflammation; Events, mechanisms, types and evolution of the inflammatory process; Chemical mediators of inflammation; Types of inflammatory lesions; Systemic effects of inflammation. Tissue repair and regeneration: Stem cells and tissue regeneration; Tissue repair and its alterations; Wound healing; Fibrosis. Atherosclerosis.
Metabolic disorders: Disorders of lipid metabolism; Disorders of carbohydrate metabolism: metabolic alterations in diabetes; Pathophysiology of blood and disorders of hemopoiesis.
