Chapter 7.4, Problem 5AYLO
Summary Introduction
To discuss:
How calcitriol is synthesized and the mechanism by which it supports or raises blood calcium level.
Introduction:
Mineralization is a process (crystallization) that deposits phosphate, calcium, and other ions (from blood plasma) in the tissues of the bone as hydroxyapatite. This process is initiated by the osteoblast by laying collagen fibers on the surface of the osteon. These fibers are coated with minerals that make the matrix hard. Only if the concentration of the products (of above minerals) in the plasma reaches the critical value (solubility product), the hydroxyapatite is formed. Sometimes, calcification is repressed by some inhibitors found in the tissue. This inhibitor is deactivated by osteoblast, and it enables the precipitation of the salt in the matrix of the bone. The initially formed crystals perform like a “seed of crystals” that attract more phosphate and calcium from the plasma.

We will be starting a group project next week where you and your group will research and ultimately present on a current research article related to the biology of a pathogen that infects humans. The article could be about the pathogen itself, the disease process related to the pathogen, the immune response to the pathogen, vaccines or treatments that affect the pathogen, or other biology-related study about the pathogen.
I recommend that you choose a pathogen that is currently interesting to researchers, so that you will be able to find plenty of articles about it. Avoid choosing a historical disease that no longer circulates.
List 3 possible pathogens or diseases that you might want to do for your group project.
