This video shows the process of vascular degneration starting with intimal trauma, fatty streaking and plaque formation which can lead to leg pain (claudication), heart attack and stroke.
Fat: Part 3 of 4 "Fueling Up"
Describes how we transfer energy from one animal or plant to another. Also discusses the gastrointestinal tract and its role in the break down and transport of triglycerides and fat via the bowel, portal vein, liver and fat cells. Finally, the video provides an explanation of a high serum triglyceride level and its effect on health.
Fat: Part 1 of 4 "Free Fatty Acids and Triglycerides"
Describes the basic biochemistry of the energy storing molecule, the free fatty acid and it's storage form in plants and animals, the triglyceride.
Fat: Part 2 of 4 "Saturated, Unsaturated & Trans fats, Cholesterol & Fossil Fuels"
Describes the molecular and physical differences between a saturated and unsaturated fat and their effect on the fatty transport vehicle, the lipoprotein. Also describes the relationship of fatty acids, hydrocarbons & fossil fuels as energy storing molecules.
MRI: Basic Physics & a Brief History
This lesson describes the basic physics of Nuclear Magnetic Resonance and relevant terms such as T1 & T2 relaxation, pulse sequence, frequency and phase encoding, T1WI and T2WI. Introduces the landmark papers of Drs. Damadian and Lauterbur that made magnetic resonance imaging a reality.
