This is a case of a hypertrophic cardiomyopathy with preserved ejection fraction. A hypertrophied left ventricle is a echocardiographic sign that there is chronic stress put in the left ventricle, most commonly in overcoming high aortic pressures in patients with systemic hypertension. In this case, there is normal chamber volume and normal ejection fraction therefore the heart is functionally normal and ejection fraction is preserved.
Mitochondria are found in all body cells.
A single gene could be inserted into a plant's genome, enabling specific traits to be expressed easily. Scientists have identified genes for two enzymes needed to make pro-vitamin A. One of these genes comes from corn.
