Useful Instructional Strategies for Literature-Based Instruction. There are many different strategies that research has shown are effective in literature-based instruction (Cooper, 1993). These include scaffolding of instruction, modeling, cooperative learning, student choices, self-initiated reading and writing, using different modes of reading, activation of prior knowledge, and student responses to literature.
What Is Peripheral Artery Disease? Peripheral artery disease (P.A.D.) is a disease in which plaque builds up in the arteries that carry blood to your head, organs, and limbs. Plaque is made up of fat, cholesterol, calcium, fibrous tissue, and other substances in the blood. When plaque builds up in the body's arteries, the condition is called atherosclerosis.
Peripheral artery disease - legs. Peripheral artery disease (PAD) is a condition of the blood vessels that supply the legs and feet. It leads to narrowing and hardening of the arteries. This causes decreased blood flow, which can injure nerves and other tissues. Peripheral artery disease is caused by arteriosclerosis, or hardening of the arteries.. This problem occurs when fatty material (plaque) builds up on the walls of your arteries and makes them narrower. The walls of the arteries also become stiffer and cannot widen (dilate) to allow greater blood flow when needed.
