There are a variety of ways of evaluating a studentâs progress and achievement in the internship. These include an evaluation of work by the on-site supervisor, a studentâs self-evaluation, a visit to the work site by the faculty sponsor, and specific academic requirements fulfilled by the student.
Regurgitation/Insufficiency (leaky valve) - the valve does not close properly and allows blood to flow backward as well as forward in the heart. The valves in your heart may be damaged due to infection, rheumatic heart disease, wear and tear, tissue weakening or deterioration, or birth (congenital) defects.egurgitation/Insufficiency (leaky valve) - the valve does not close properly and allows blood to flow backward as well as forward in the heart.

The destruction of heart muscle cells, known as cardiomyocytes, can be the result of hypertension, chronic insufficiency in the blood supply to the heart muscle caused by coronary artery disease, or a heart attack, the sudden closing of a blood vessel supplying oxygen to the heart. next step in this research is to see whether the experimental evidence of improvement in outcome from heart attack in rodents can be reproduced using embryonic stem cells. These breakthrough discoveries in rodent models present new opportunities for using stem cells to repair damaged heart muscle.
