The use of forensic DNA analysis in humanitarian forensic action: The development of a set of international standards.

DNA analysis was first applied to the identification of victims of armed conflicts and other situations of violence (ACOSV) in the mid-1990s, starting in South America and the Balkans. Argentina was the first country to establish a genetic database specifically developed to identify disappeared children. Following on from these programs the early 2000s marked major programs, using a largely DNA-led approach, identifying missing persons in the Balkans and following the attack on the World Trade Center in New York.

DNA transfer: The role of temperature and drying time.

It has previously been shown, and reconfirmed here, that biological material on a substrate will transfer readily upon contact with another substrate when wet but hardly when dry. There is however a paucity of data regarding the speed at which body fluids dry and how this may affect its transfer upon contact. Here we conduct transfer experiments at 4°C, 22°C and 40°C at multiple time points during the drying process.

Mitochondrial haplogroups associated with elite Kenyan athlete status.

Unlabelled: The maternal inheritance of mitochondrial DNA (mtDNA) has enabled construction of detailed phylogenies. Analysis of key polymorphisms from these phylogenies allows mtDNA to be assigned to haplogroups, which have been associated with elite endurance performance.

Purpose: To compare the frequencies of mtDNA haplogroups found in elite Kenyan athletes with those in the general Kenyan population.

No association between Angiotensin Converting Enzyme (ACE) gene variation and endurance athlete status in Kenyans.

East African runners are continually successful in international distance running. The extent to which genetic factors influence this phenomenon is unknown. The insertion (I) rather than deletion (D) of a 287 bp fragment in the human angiotensin converting enzyme (ACE) gene is associated with lower circulating and tissue ACE activity and with endurance performance amongst Caucasians.

Mitochondrial DNA lineages of elite Ethiopian athletes.

Previous studies have hypothesised that mitochondrial DNA (mtDNA) polymorphisms may influence aerobic performance. The matrilineal inheritance and accumulation of polymorphisms in mtDNA means that mtDNA haplogroups, characterised by key polymorphisms, are often represented at different frequencies in different populations. The present study aimed to compare the mtDNA haplogroup distribution of elite Ethiopian athletes relative to the general Ethiopian population.

Y chromosome haplogroups of elite Ethiopian endurance runners.

Favourable genetic endowment has been proposed as part of the explanation for the success of East African endurance athletes, but no evidence has yet been presented. The Y chromosome haplogroup distribution of elite Ethiopian athletes (n=62) was compared with that of the general Ethiopian population (n=95) and a control group from Arsi (a region producing a disproportionate number of athletes; n=85). Athletes belonged to three groups: marathon runners (M; n=23), 5-km to 10-km runners (5-10K; n=21) and other track and field athletes (TF; n=18).
