Short tandem repeat (STR) profile authentication via machine learning techniques
Short tandem repeat (STR) DNA profiles have multiple uses in forensic analysis, kinship identification, and human biometrics. However, as biotechnology progresses, there is a growing concern that STR profiles can be created using standard laboratory techniques such as whole genome amplification and …

An enzymatic means for the rehabilitation of low-copy number and degraded DNA.
… the abundance of PCR products across all short tandem repeat (STR) loci using the DNA exonuclease, duplex-specific nucelase (DSN).

High-throughput Amplicon Sequencing Optimization for Downstream Prediction Purposes
Alongside short tandem repeat (STR) typing, forensic DNA phenotyping (FDP) can enhance forensic DNA analysis by inferring externally visible characteristics and biogeographical ancestry from single-nucleotide polymorphisms (SNPs). This project involves the optimization of a high-throughput amplicon …

Evaluation of storage conditions on DNA used for forensic STR analysis
Short tandem repeat (STR) analysis is currently the most common method for processing biological forensic evidence. STRs are highly polymorphic and allow for a strong statistical power of discrimination when comparing deoxyribonucleic acid (DNA) samples. Since sample testing and court proceedings …

A Novel SNP Genotyping Technique to Determine Orangutan Relatedness and Genetic Diversity at Camp Leakey in Tanjung Puting, Central Kalimantan
… technique through standard microsatellite short tandem repeat (STR) micro-capillary genotyping. I estimate genetic diversity and relatedness (<em>r</em>) for 32 (21 female and 9 male) wild orangutans at the Camp Leakey Study Site. I successfully isolated 125 known human SNP loci (0.08% of …

The Use And Development Of Laser Microdissection To Separate Spermatozoa From Epithelial Cells For Str Analysis
Short Tandem Repeat (STR) analysis has become a valuable tool in identifying the source of biological stains, particularly from the investigation of sexual assault crimes. Difficulties in analysis arise primarily in the interpretation of mixed genotypes when cell separation of the sexual …

Aspects of human relationship identification using short tandem repeats
Human short tandem repeat (STR) loci identification can be for linking material from a crime scene to an individual or linking two individuals. Paternity testing is one form of linkage where typically samples are tested between the mother, child and putative father (trio) and a probability (CPI) of …

A Novel Forensic DNA Profiling Method Based On Molecular Beacons Without Dna Purification
… the accepted method of analysis for profiling is Short Tandem Repeat (STR) profiling. This is a lengthy process, typically taking up to 3 days. The time necessary to generate an STR profile, along with the ever-increasing reliance on DNA to solve crimes, has led to a large DNA sample backlog, with …

Dna Profiling of Captive Roseate Spoonbill (Ajaia Ajaja) Populations As a Mechanism of Determining Lineage in Colonial Nesting Birds.
… expected. Five polymorphic Spoonbill autosomal short tandem repeat (STR) loci [three (GAT)n, one (AAAG)n and one (GT)n] and one Z/W-linked microsatellite exhibiting sex-specific dimorphism were isolated and characterized. The Z/W-linked STR locus accurately confirmed the sex of each bird. …

Impact of heated passive headspace concentration on DNA recovery from semen in fire-scene evidence
… assessed. DNA yield, degradation index (DI) and short tandem repeat (STR) profiles served as outcome measures.When not contaminated with gasoline, about 60 ng of DNA (DI≈1.6) could still be recovered from normal semen samples after HPHC treatment for 6 hours, and a complete STR profile with high …

A Molecular Anthropological Study of Altaian Histories Utilizing Population Genetics and Phylogeography
… was characterized with biallelic markers and short tandem repeat (STR) haplotypes. Overall, this work provided a high-resolution data set for both unipaternally inherited genetic marker systems. The resulting data were analyzed using both population genetic and phylogeographic methods. …

The analysis of Y chromosome polymorphisms in populations of the United Arab Emirates
… UAE Police DNA laboratory needed to develop a Y Short Tandem Repeat (STR) marker database for three major groups (the UAE Arab, Indian and Pakistani populations) in order to allow the use of Y STRs in forensic case work. This project was designed to develop the Y STR haplotype database using an …

Development of Y-STR genotyping systems suitable for sexual assault cases in South Africa
… study was therefore to develop non-commercial Y-STR genotyping systems suitable for sexual assault cases in South Africa. Y-chromosome STR loci constituting the minimal haplotype are still the most widely used loci in investigating sexual assault cases despite the fact that DYS391 and DYS392 have …
