Lower Diversity of Amylase-Trypsin Inhibitors and -Released Opioid-Containing Peptides in Ancestral Compared to Modern Wheat Varieties Assessed by Proteomics and Peptidomics.

This study focused on identifying amylase-trypsin inhibitors (ATIs) in seven Norwegian-cultivated wheat varieties, including common wheat and ancestral species, and identifying potentially harmful opioid peptides within the digesta of these wheats. LC-MS/MS analysis of tryptic peptides from ATI fractions revealed that the common wheat variety Børsum exhibited the highest diversity of ATIs ( = 24), while they were less represented in tetraploid emmer ( = 11). Hexaploid wheat Bastian showed low diversity and relative abundance of ATIs.

A comparison of likelihood ratios calculated from surface DNA mixtures using MPS and CE Technologies.

This study evaluates the performance of analysing surface DNA samples using massively parallel sequencing (MPS) compared to traditional capillary electrophoresis (CE). A total of 30 samples were collected from various surfaces in an office environment and were analysed with CE and MPS. These were compared against 60 reference samples (office inhabitants).

A comprehensive characterization of MPS-STR stutter artefacts.

Interpretation of DNA evidence involving mixtures is challenging when alleles from minor contributors coincide with stutters from major contributors. To accommodate this, it is important to have a good understanding of stutter sequence formation trends. Here, multiple stutter types were characterized based on massively parallel sequencing (MPS) data from 387 single source samples, using the Verogen ForenSeq™ DNA Signature Prep kit.

Effect of sprouting on the proteome of chickpea flour and on its digestibility by ex vivo gastro-duodenal digestion complemented with jejunal brush border membrane enzymes.

The demand for sustainably produced proteins is increasing with the world population and is prompting a dietary shift toward plant sourced proteins. Vegetable proteins have lower digestibility and biological value compared to animal derived counterparts. We explored sprouting of chickpea seeds as a strategy for improving digestibility.

Determination of shedder status: A comparison of two methods involving cell counting in fingerprints and the DNA analysis of handheld tubes.

The shedder status of an individual may be important to consider in the context of DNA transfer, persistence and recovery and in Bayesian networks where a person's shedder status may have an impact on the outcome. In this study we compared two methods to determine shedder status: the handheld tube (HH) method and a fluorescent cell count (CC) method. A poor association was observed between the numbers of detected cells in a fingerprint using the CC method and the strength of the DNA result with the HH method.
