In a population of 1000 individuals, 500 new individuals were born and 200 individuals died over the course of 1 year. Which equ
blagie [28]

(Initial individuals + newborn individuals) - dead individuals = total individuals

Growth rate = (total individuals/initial individuals) * 100

Population growth rate = new percentage minus 100%

Calculations

(1000 + 500) - 200 = 1500 - 200 = 1300

Growth rate = (1300/ 1000) * 100

= 1.3 * 100

= 130%

Population growth rate = 130% - 100%

= 30% per year if it is uniform

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.
