Kapoor 2014. Effect of orthodontic forces on cytokine and receptor levels in gingival crevicular fluid: A systematic review.
Alchen [17]

The publication about the effect of orthodontic forces on cytokine and receptor levels in gingival fluid investigates how this treatment can increase inflammation.

<h3>What are cytokines?</h3>

Cytokines are molecules of the immune system that act during different types of immune responses, especially in inflammatory pathways.

Cytokines are mainly secreted by helper T immune cells (T cells) and macrophages.

In this case, the publication above mentioned uses different cytokine biomarkers to test inflammatory responses after orthodontic treatment (e.g., IL-1β, TNF-α, IL-8, etc).

In conclusion, the publication about the effect of orthodontic forces on cytokine and receptor levels in gingival fluid investigates how this treatment can increase inflammation.

Which answer helps to explain why all living cells need ph buffers?
defon

Answer;

Amino acid side chains have many carboxyl and amino groups.

Explanation;

-A buffer solution is a solution that resists changes in pH when small quantities of an acid or an alkali are added to it. It is a chemical substance that helps maintain a relatively constant pH in a solution, even in the face of addition of acids or bases.

-Buffering is important in living systems as a means of maintaining a fairly constant internal environment, also known as homeostasis.Small molecules such as bicarbonate and phosphate provide buffering capacity as do other substances, such as hemoglobin and other proteins.

- Protein buffer systems depend upon proteins, as opposed to nonprotein molecules, to act as buffers and consume small amounts of acid or base. Since amino acids have the capability of reacting with both acid and base, they naturally act as buffers.
