Advanced Topics in Biomedical Science

Summary:

The note titled “Advanced Topics in Biomedical Science” provides a comprehensive overview of various diseases and conditions in the field of biomedical science. It covers various topics, from cellular changes in disease to specific medical conditions like hypertension, myocardial infarction, cerebrovascular stroke, Alzheimer’s disease, dengue fever, MERS, Zika virus, pulmonary edema, rheumatoid arthritis, osteoarthritis, and hepatitis.

The first section, “Cellular Changes in Disease,” explores the alterations that occur at the cellular level during disease processes, spanning from pages 2 to 4. The subsequent section, “Pharmacology,” delves into the study of drugs and their effects, covering pages 5 to 7.

Moving on to specific medical conditions, “Hypertension” is discussed on pages 7 to 9, focusing on the elevated blood pressure that can lead to serious health complications. “Myocardial Infarction,” covered on pages 9 to 11, delves into the condition commonly known as a heart attack. Pages 12 to 13 are dedicated to “Cerebrovascular Stroke,” addressing the disruption of blood flow to the brain and its consequences.

The note then shifts its attention to neurodegenerative disorders, with “Alzheimer’s Disease” examined on pages 13 to 15. “Dengue Fever” follows on pages 15 to 17, detailing the viral infection transmitted by mosquitoes. Subsequently, “MERS” (Middle East Respiratory Syndrome) is discussed on pages 17 to 18, focusing on the respiratory illness caused by the coronavirus. “Zika Virus” is briefly mentioned on page 18, highlighting its association with birth defects.

The note further covers “Pulmonary Edema,” characterized by fluid accumulation in the lungs, on pages 18 to 20. “Rheumatoid Arthritis,” a chronic inflammatory condition affecting joints, is explored on pages 20 to 22. Finally, “Osteoarthritis” is briefly touched upon on page 22, referring to the degenerative joint disease. The note concludes with “Hepatitis” on pages 23 to 25, discussing liver inflammation caused by viral infections.

Overall, this comprehensive note provides a valuable resource for understanding cellular changes in disease and various medical conditions within the field of biomedical science, offering insights into their causes, symptoms, and potential treatments.

Cellular Changes in Disease

Cell Injury: most injurious agents cause damage via the production of free radicals, impaired oxygen delivery or utilization, of which some can be reversed and recovered, whilst some may be irreversible, causing cell death & necrosis
