Sequenced-based French population data from 169 unrelated individuals with Verogen's ForenSeq DNA signature prep kit.

Massively Parallel Sequencing (MPS) applied to forensic genetics allows the simultaneous analysis of hundreds of genetic markers and the access to full amplicon sequences which help to increase available allele diversity. Meanwhile, sequence variation within the repeat regions represents the majority of the allele diversity, flanking regions adjacent to the repeat core provide an additional degree of variation. The forensic genetics community needs access to population data, from relevant parts of the world that contain this new sequence diversity in order to perform statistical calculations.

The Production and Delivery of Probiotics: A Review of a Practical Approach.

To successfully deliver probiotic benefits to the consumer, several criteria must be met. Here, we discuss the often-forgotten challenges in manufacturing the strains and incorporating them in consumer products that provide the required dose at the end of shelf life. For manufacturing, an intricate production process is required that ensures both high yield and stability and must also be able to meet requirements such as the absence of specific allergens, which precludes some obvious culture media ingredients.

Automation and developmental validation of the ForenSeq DNA Signature Preparation kit for high-throughput analysis in forensic laboratories.

Massively parallel sequencing (MPS) applications in forensic science highlight the advantages of this technique compared to capillary electrophoresis (CE). The multiplexing of a wide range of genetic markers and access to the full amplicon sequence, allowing the detection of isoalleles, make it a very promising tool which could be applied to the most challenging casework DNA samples. However, the complexity of the manual library preparation protocol, potential DNA contamination and sample tracking issues are the main reasons why forensic scientists still hesitate to implement MPS analytical workflows in their laboratory.

New genetic evidence of affinities and discontinuities between bronze age Siberian populations.

Objectives: This work focuses on the populations of South Siberia during the Eneolithic and Bronze Age and specifically on the contribution of uniparental lineage and phenotypical data to the question of the genetic affinities and discontinuities between western and eastern populations.

Materials And Methods: We performed molecular analyses on the remains of 28 ancient humans (10 Afanasievo (3600-2500 BC) and 18 Okunevo (2500-1800 BC) individuals). For each sample, two uniparentally inherited systems (mitochondrial DNA and Y-chromosome DNA) were studied, in order to trace back maternal and paternal lineages.

The genetics of kinship in remote human groups.

For fifteen years, part of the work of our research team has been focused on the study of parental links between individuals living hundreds or thousands of years ago, whose remains have been found in single graves or large funerary complexes. These studies have been undertaken using methods developed by forensic genetics to identify individuals, mainly based on the genotyping of autosomal STR (Short Tandem Repeats). Issues arose from this work, namely the limits of studying small numbers of subjects, originating from groups of finite sizes where kinships cannot be inferred a priori and for which reference allelic frequencies do not exist.
