Viral infection and sudden non-cardiac death: A systematic review.

Introduction: Sudden non-cardiac death (SNCD) is a clinical entity comprising deaths lacking previous clinically significant symptoms, and in which the mechanisms of death do not involve the heart. Infection is a major cause of SNCD, particularly in children, and viruses are frequently involved in the disease process. Nevertheless, SNCD of viral infectious causes remains poorly characterized.

Post-mortem genetic investigation in sudden cardiac death victims: complete exon sequencing of forty genes using next-generation sequencing.

Sudden cardiac death (SCD) in young people is predominantly caused by genetic causes as cardiomyopathies. Hypertrophic cardiomyopathy is the most common genetic cardiovascular disease and is responsible for the major proportion of SCD in the young. The purpose of this study was to identify the genetic variants present in young SCD victims with HCM characteristics.

Contribution to the Development of Guidelines in the Analysis of Biological Evidence in Sexual Assault Investigations.

This investigation intends to study materials and techniques used for biological evidence collection in sexual assault cases and is divided into two stages: in stage one, methods for biological evidence collection (the single swab (including three variants) and the "double swab technique") were compared; in stage two, swabs' component material was compared. The sampling was composed of 42 heterosexual couples who provided mock samples. The collection methods in which the whole swab is covered by evidence presented significantly better outcomes (p < 0.

A Comparison Among Three Multiplex Y-STR Profiling Kits for Sexual Assault Cases.

Biological evidence of sexual assault is one of the most difficult sample types to analyze in forensic laboratories. Y-STR markers are thus a valuable tool for analyzing these samples. The aim of this project was to compare three Y-STR commercial kits by analyzing their amplification performance on casework samples.

The Use of Laser Microdissection in Forensic Sexual Assault Casework: Pros and Cons Compared to Standard Methods.

Sexual assault samples are among the most frequently analyzed in a forensic laboratory. These account for almost half of all samples processed routinely, and a large portion of these cases remain unsolved. These samples often pose problems to traditional analytic methods of identification because they consist most frequently of cell mixtures from at least two contributors: the victim (usually female) and the perpetrator (usually male).

Technical Note: "Mitochondrial and nuclear DNA approaches for reliable identification of Lucilia (Diptera, Calliphoridae) species of forensic interest from Southern Europe".

In forensic entomology, rapid and unambiguous identification of blowfly species is a critical prerequisite for accurately estimating the post-mortem interval (PMI). The conventional diagnosis of cadaveric entomofauna based on external characters is hampered by the morphological similarities between species, especially in immature stages. Genetic analysis has been shown to allow precise and reliable diagnosis and delimitation of insect species.

Cytochrome b as a useful tool for the identification of blowflies of forensic interest (Diptera, Calliphoridae).

In Forensic Entomology the fast and accurate identification of insects collected at the scene of events is essential if errors are to be avoided in estimating infestation times of interest and determining the post-mortem interval (PMI). Traditional identification based on morphological characteristics can be complicated due to physical similarities between different species, especially at immature stages. Genetic analysis provides a fast and reliable identification method.

Genetic data of a Brazilian population sample (Santa Catarina) using an X-STR decaplex.

The study of X-chromosomal short tandem repeats (X-STRs) can complement the analysis of autosomal and Y-STRs. A decaplex system for the X-chromosome genetic markers, DXS8378, DXS9898, DXS7133, GATA31E08, GATA172D05, DXS7423, DXS6809, DXS7132, DXS9902 and DXS6789, was used to study a population sample of Santa Catarina, Brazil. 184 individuals (72 female and 112 male samples) were typed.

Mitochondrial DNA diversity in a population from Santa Catarina (Brazil): predominance of the European input.

The state of Santa Catarina (Brazil) is known to have represented a cultural crossroads in South America due to several historic migrations mainly from Europe and Africa. We set out to scrutinize whether the genetic imprint of these migrations could be traced through analysis of the matrilineal gene pool of the Catarinenses. The entire control region of the mitochondrial DNA was studied in 80 healthy and maternally unrelated individuals.

Y-chromosomal STR haplotype diversity in males from Santa Catarina, Brazil.

One-hundred and nine unrelated and healthy males from Santa Catarina, Brazil were included in this study. Allele frequencies and gene diversities for the loci DYS456, DYS458 and DYS448 were calculated. A comparison between our population and others was performed.

Analysis of 10 X-linked tetranucleotide markers in mixed and isolated populations.

We have applied a recently described X-STRs decaplex to characterize four population groups of the Iberian Peninsula, including two well mixed populations and two relatively isolated ones from Northern Spain, in order to get a better insight about the characteristics of X-STRs in those population types between-population differences in allelic frequencies were relatively small. Nevertheless, Fst values were between 0.2 and 2.

A GEP-ISFG collaborative study on the optimization of an X-STR decaplex: data on 15 Iberian and Latin American populations.

In a collaborative work carried out by the Spanish and Portuguese ISFG Working Group (GEP-ISFG), a polymerase chain reaction multiplex was optimized in order to type ten X-chromosome short tandem repeats (STRs) in a single reaction, including: DXS8378, DXS9902, DXS7132, DXS9898, DXS6809, DXS6789, DXS7133, GATA172D05, GATA31E08, and DXS7423. Using this X-decaplex, each 17 of the participating laboratories typed a population sample of approximately 200 unrelated individuals (100 males and 100 females). In this work, we report the allele frequencies for the ten X-STRs in 15 samples from Argentina (Buenos Aires, Córdoba, Río Negro, Entre Ríos, and Misiones), Brazil (São Paulo, Rio de Janeiro, Paraná, and Mato Grosso do Sul), Colombia (Antioquia), Costa Rica, Portugal (Northern and Central regions), and Spain (Galicia and Cantabria).

DNA typing of Diptera collected from human corpses in Portugal.

Medico-legal entomology, one area in the broad field of entomology, is routinely used in forensic applications. Insects are often collected from a corpse during criminal information related to the body, but requires the fast and accurate identification of the species attracted to the remains. The local entomofauna in most cases is important for explaining entomological evidence.

Genetic data of four X-chromosomal STRs in a population sample of Santa Catarina, Brazil.

Genetic data of 4 X-chromosomal short tandem repeats in a North of Portugal population.

One hundred unrelated females and 100 unrelated males, autochthonous, healthy, from the North of Portugal.

Allele frequencies of sixteen STRs in the population of Northern Portugal.

Allele frequencies of sixteen autossomal short tandem repeats (STRs), D3S1358, VWA, D16S539, D8S1179, D21S11, D18S51, TH01, FGA, D5S818, D13S317, D7S820, TPOX, CSF1PO, Penta D, Penta E (included in the PowerPlex 16 kit), and the SE33 (PowerPlex ES Monoplex System SE33) were determined in a sample of 200 healthy unrelated individuals from the north of Portugal.

Allele frequencies and haplotypes of 8 Y-chromosomal STRs in the Santa Catarina population of southern Brazil.

Allele frequencies and haplotypes of eight Y-chromosomal short tandem repeats (STRs), DYS19, DYS385, DYS389 I, DYS389 II, DYS390, DYS391, DYS392 and DYS393 were determined in a sample of 109 males from Santa Catarina. The origin of this southern Brazilian population is mainly from Portuguese people, namely from Azores archipelago.
