infection in Cuban adolescent and young populations.

Background: In Cuba, little is known regarding the prevalence of (CT) infection in adolescents and young people. We study the frequency of CT infection in these populations, and its association with clinical-epidemiological variables.

Methods: A total of 496 individuals aged 12 to 24 were recruited from November 2018 to November 2019.

Cell Immortalization: In Vivo Molecular Bases and In Vitro Techniques for Obtention.

Somatic human cells can divide a finite number of times, a phenomenon known as the Hayflick limit. It is based on the progressive erosion of the telomeric ends each time the cell completes a replicative cycle. Given this problem, researchers need cell lines that do not enter the senescence phase after a certain number of divisions.
