For the answer to the question above, I think that <span>the initial titer that has been done to her may have been done too early in the infection that detectable levels of antibody were not present yet so that's why they have to repeat it.</span>
The t<u>unica media</u> is composed of an endothelial layer that is continuous with the endocardium of the heart.
<h3>What is tunica media?</h3>
Collagen, elastin, and smooth muscle cells make up tunica media. It is located halfway between the tunica externa and the tunica intima. The transverse arrangement of its strands and color make the middle coat (tunica medium) distinct from the inner (tunica intima). It not only supports the vessel but also alters the vessel's width to control blood pressure and flow.
Elastic fibers make up the majority of the tunica media in bigger vessels. The number of elastic fibers reduces as arteries get smaller, whereas the number of smooth muscle fibers grows. The strongest of the three layers is the tunica adventitia, which is the top layer. Elastic and collagenous fibers make up its structure.

Fungi reproduce asexually by fragmentation, budding, or producing spores. Fragments of hyphae can grow new colonies. Mycelial fragmentation occurs when a fungal mycelium separates into pieces with each component growing into a separate mycelium. There are many types of asexual spores.
The type of hormone, such as the steroid, which passes directly through the cell membrane to nuclear receptors to cause changes in gene expression within the cell, is known as hydrophobic.
Hydrophobic steroid hormones are transported in the circulation, largely bound to plasma carrier proteins. Steroids are overall hydrophobic because of they have common tetracyclic hydrocarbon core.
Hence, the steroid hormones are lipid-soluble in hydrophobic environments and they able to pass through the cell membrane of cell. Steroid hormones have the ability bind with receptors and change their structure and causing that complex to easily pass into the nucleus in order to alter or change gene expression.
