BACKGROUND: Maturation is the irreversible biological process leading to adult form or function. The degree of maturation can be derived from the examination of maturity indicators, i.e. of particular aspects of the overall maturation, such as pubertal status, skeletal and dental morphology. Rhythm of maturation of each indicator differs between populations and individuals, because of genetic, nutritional and environmental factors. Skeletal maturation is usually expressed as skeletal age, which is the median age at which a given degree of maturation is attained...

Humans constantly lose epithelial cells, and these biological traces are frequently studied in the context of criminal investigations. The objective of this work was to examine the genetic profile in samples of forensic interest (nail and skin epithelial cells) of bone marrow transplant patients and discuss its forensic and clinical implications. The genetic profile of nail, epidermal cells and blood samples of patients receiving HSCT was analyzed by the amplification and sequencing of 38 insertion/deletion polymorphisms and 15 short tandem repeat polymorphisms...

The application of massively parallel sequencing (MPS) in forensic sciences enables high-resolution short tandem repeat (STR) genotyping for the characterization of biological evidence. While MPS supports multiplexing of a large number of forensic markers, the performance of an MPS-STR panel depends on good primer design and optimal PCR conditions. However, conventional strategies for multifactorial assay optimization are labor-intensive and do not necessarily allow the experimenter to identify optimum factor settings...

Hainan Island is the southernmost and smallest Chinese province, isolated from the mainland. The Li and Han ethnic groups account for over 98% of the population on the island. However, the Li ethnic group is an indigenous community of Hainan Island, with great differences in culture, language and origin with respect to the Han, the largest ethnic group. Here, we studied these two ethnic groups from the perspective of the Y-chromosome single nucleotide polymorphisms (Y-SNPs) and short tandem repeats (Y-STRs) to unravel their forensic and phylogenetic characteristics...

The reported rate of sex crimes, some of the most severe acts of violence that can be perpetrated against an individual, is increasing across all societies, regardless of gender or age of the victim. Sexual abuse has been defined, in part, as the involvement of a child in sexual activity for which they are incapable of giving consent, that they cannot fully comprehend, or for which they are developmentally immature. Molestation of the anorectal region is frequently encountered when the victim of sexual abuse is a male child...

Mitochondrial DNA sequence data is often utilized in disease studies, conservation genetics and forensic identification. The current approaches for sequencing the full mtGenome typically require several rounds of PCR enrichment during Sanger or MPS protocols followed by fairly tedious assembly and analysis. Here we describe an efficient approach to sequencing directly from genomic DNA samples without prior enrichment or extensive library preparation steps. A comparison is made between libraries sequenced directly from native DNA and the same samples sequenced from libraries generated with nine overlapping mtDNA amplicons on the Oxford Nanopore MinION device...

AIM OF THE STUDY: Genetic tests play a crucial role in the crime investigation process and often provide the strongest evidence for case resolution. Although the majority of genetic analyses in the field of criminalistics focus on the human DNA, genetic identification of animals is becoming an increasingly common procedure. Domestic animals, which live around people, may be silent witnesses and even victims of criminal activity. Their typically limited value as evidence in such cases could radically change thanks to the possibility of using animal biological material present at the crime scene...

BACKGROUND: China harbors 56 ethnic groups, including Korean, with a population size of approximately 1.92 million at the 2010 census. Most of the Koreans live in Northeastern parts of China, including Jilin (59.64%), Heilongjiang (20.21%), and Liaoning (12.55%) provinces, and the rest are spread to other parts of China. Koreans across China share a common culture, which is similar to Korea. METHODS: We have explored the genetic characteristics of 20 Y-chromosomal short tandem repeat (Y-STR) loci in 252 unrelated Chinese Korean male individuals from Jilin Province, using a Goldeneye 20Y amplification kit...

In this study, 27 Y-STRs were analyzed in 347 male individuals from the Yanbian Korean population. Haplotype diversity (HD) and discrimination capacity (DC) values were calculated. Pairwise Rst values were evaluated in AMOVA analysis and visualized through multidimensional scaling (MDS). Yflier Plus system indicated higher Discrimination Power (DP), HD and DC which is 0.9969, 0.9998 and 0.9769. There is no significant genetic distance between Yanbian Koreans and South Koreans, however, there is a great distance from Chinese Han population...

The objective of the present study was the analysis of expert activities of the forensic biological, forensic cytological, and molecular genetic divisions and laboratories of the state agencies carrying out forensic medical expertise in the Russian Federation during the past 15 year period (2003-2017). We scrutinized the data on the organizational structure and the personnel scheduling chart of the aforementioned units. The study has demonstrated the progressive decrease in the number of forensic biological and forensic cytological investigations versus enhanced activities of the molecular genetic laboratories...

China is a multinational country composed of 56 ethnic groups of which the Han Chinese accounts for 91.60%. Qinghai Province is located in the northeastern part of the Qinghai-Tibet Plateau, has an area of 72.12 km2 , and is the fourth largest province in China. In the present study, we investigated the genetic polymorphisms of 20 short tandem repeat (STR) loci in a Qinghai Han population, as well as its genetic relationships with other populations. A total of 273 alleles were identified in 2 000 individuals at 20 loci, and the allelic frequency ranged from 0...

The domestication of wild vicuña and guanaco by early pre-Inca cultures is an iconic example of wildlife management and domestication in the Americas. Although domestic llamas and alpacas were clearly selected for key, yet distinct, phenotypic traits, the relative patterns and direction of selection and domestication have not been confirmed using genetic approaches. However, the detailed archaeological records from the region suggest that domestication was a process carried out under significant control and planning, which would have facilitated coordinated and thus extremely effective selective pressure to achieve and maintain desired phenotypic traits...

Inferring an individual's ancestry or group membership using a small set of highly informative genetic markers is very useful in forensic and medical genetics. However, given the huge amount of SNP data available from a diverse of populations, it is challenging to develop informative panels by exhaustively searching for all possible SNP combinations. In this study, we formulate it as an algorithm problem of selecting an optimal set of SNPs that maximizes the inference accuracy while minimizes the set size. Built on this conception, we develop a computational approach that is capable of constructing ancestry informative panels from multi-population genome-wide SNP data efficiently...

We performed forensic investigations on a handkerchief containing seminal fluid deposited 100 years earlier. The aim was to verify the possibility to achieve a complete genetic profile exceeding the limit of success reached until today with a partial semen stain profile stored up to 50 years. The current forensic methods were carried out: Alternative Light Source (ALS), Prostate-Specific Antigen (PSA) Test, autosomal and Y-chromosome Short Tandem Repeats (STRs). ALS inspection was a crucial method in the success of the analysis...

Microhaplotype markers are emerging forensic genetic markers that have received broad attention in forensics and may supplement existing genetic marker panels. Short tandem repeat polymorphisms (STRPs) and single nucleotide polymorphisms (SNPs) are the general genetic markers at present. Stutter and the high mutation rate of STR markers and the low polymorphism of SNP markers obstruct the solving of certain cases. Kidd proposed microhaplotype markers that encompass 2-4 SNPs. In this study, we screened microhaplotype loci through three criteria, and chose the Illumina® MiSeq platform to sequence the new markers...
