Received July 18‚ 1997X A radiochemical enzyme assay for studying cyclooxygenase (COX)-catalyzed prostaglandin biosynthesis in vitro was optimized with respect to both COX-1 and COX-2 activity. The assay can be used to assess the relative selectivity of plant-derived inhibitors on COX-1 and COX-2. Assay conditions were optimized for both enzymes with respect to concentration of cofactors (l-epinephrine‚ reduced glutathione‚ and hematin)‚ activation time (enzyme and cofactors)‚ reaction time‚ and

While staying with the topic of astronomy‚ this paper will describe the discovery of antimatter‚ the origins of antimatter‚ and antimatter as energy. To describe antimatter we must first look at the history in its discovery. The history of discovering antimatter begins in 1929 by the proposal of an English Physicist named Paul Dirac. In attempting to combine quantum mechanics with special relativity to

Hypothesis: The assay system used in the lab consists of a filter paper disc coated with the enzyme and the dropped into a papercup of substrate (Hydrogen Peroxide). As the hydrogen breaks down the hydrogen peroxide into hydrogen and oxygen gas‚ the bubbles of oxygen gas collect underneath the filter and make it

Discoveries can affect our vision of the world‚ do you agree? Discovery is when you find or explore different aspects of something you don’t often know about or a lot of. There are many types of different discoveries you can make such as physical‚ historical‚ emotional‚ random‚ personal and accidental discoveries. “Martin and The Hand Grenade” by John Foulcher‚ “Looking for Alibrandi” by Melina Marchetta and “Erin Brochovich” directed by Steven Soderberghall all endure the theme discovery in

Archaeological discoveries made in the 1920s play a vital role in understanding how and when ancient Americans and their descendants resided in North America. Their culture and way of life. In the following paragraph I will discuss how the Folsom discoveries helped scholars understand the migration of ancient American into the Western Hemisphere‚ their origin as well as the geological condition that facilitated the migration. And finally how the interaction between Native American and the environment

Self Discovery: After Self-Discovery Already Happened The feeling of personal identity is one that is engraved into the being of every human from a very young age. Through countless life experiences‚ some good and some bad‚ this sense of who we are and what our purpose is as human beings changes.

Was Columbus’s discovery epochal? Many of us have grown up believing from our earliest school years that Christopher Columbus was the voyager who found America. In between the centuries several European explorers navigated around the world searching for treasures and new lands. Of all the explorers‚ Columbus is the most celebrated and acknowledged - for supposedly founding America in 1492. Columbus was born in Italy in 1452‚ of humble origins; he grew up surrounded by
