Those originally employed were based either on the fusion of the PCE to a tumour specific antibody (Antibody-Directed Prodrug Therapy, ADEPT) or on the delivery of the gene encoding the PCE using viral or non-viral vectors (Gene-Directed Enzyme Prodrug Therapy, GDEPT).
Urea is widely used in fertilizers as a source of nitrogen and is an important raw material for the chemical industry. Friedrich WÃ¶hler's discovery in 1828 that urea can be produced from inorganic starting materials was an important conceptual milestone in chemistry.
Take a close look at the way starchy and non-starchy vegetables behave in our bodies and you might be surprised to discover good reasons to eat both kinds of plant foods. What Are Starchy and Non-Starchy Vegetables? Vegetables are labeled starchy when they contain more carbohydrates and more calories compared to other (non-starchy) vegetables. Here's a list of common vegetables in the starchy category: corn, peas, potatoes, zucchini, parsnips, pumpkin, butternut squash and acorn squash. The non-starchy vegetables category is much larger and includes veggies like spinach, celery, broccoli, radishes, onions, garlic, tomatoes, cucumbers, carrots and beets. Non-starchy vegetables deliver a powerful punch of vitamins, minerals and phytonutrients.
