Answer:
Thyrocalcitonin or TCT
Explanation:
Thyrocalcitonin or TCT is a non-iodinated calcium lowering hormone. It is originating from the parafollicular cells or C cells (C for calcium).
The thyroid gland consists of follicles of cuboidal epithelial cells. These cuboidal cells have a nucleus at the base. These are principal cells responsible for the synthesis of thyroid hormones.
In between these follicular cells, other high cuboidal cells are present, known as parafollicular cells / C cells. These cells synthesise the hormone TCT. When there is high levels of calcium ions in the serum, TCT will release. This lowers the high level of calcium ions in the blood and plasma to normal level. This is done due to the deposition of calcium in the bone.
The correct answer is - Since 2000, more people are living with HIV, but fewer people are dying from AIDS.
Since the year 2000, the number of people that are living with HIV has been steadily increasing, though it has to be noted that the rise has been gradually slowing down. On the other hand, despite having more living with HIV, the deaths by AIDS have reduced gradually.
The main reason for the increase of people living with HIV is simply that there's more and more people in the world that can contact physically much more easily, so the disease can be transferred much more easily over larger distances. On the other hand, less and less people are dying from AIDS, and the reason for that is the discovering of the disease in its early stage, as well as the development of the medicine and keeping a certain routine in the lifestyle that is healthy.
