Genetic Diversity Based on the Analysis of 27 Y- Short Tandem Repetition (STR) Loci in Two Populations in the Apuseni Mountains, Romania.

Background: Y chromosome analysis is used in various fields of forensic genetics, genetic genealogy, and evolutionary research, due to its unique characteristics. Short tandem repetitions (STR) are particularly relevant in population genetic studies. The aim of this study is to analyze the genetic profile of two populations in the Apuseni Mountains area, Băița and Roșia Montană, Romania.

For centuries, death has been defined, medically speaking, as the irreversible cessation of breathing and of nervous and cardiac activity. What radically changed this definition was the introduction of the concept "brain death" in 1968, by the "Ad Hoc Committee of the Harvard Medical School".
