Transformations for compositional data with zeros with an application to forensic evidence evaluation [PDF]

, 2011
In forensic science likelihood ratios provide a natural way of computing the value of evidence under competing propositions such as "the compared samples have originated from the same object" (prosecution) and "the compared samples have originated from ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Canopy influence on trace metal atmospheric inputs on forest ecosystems: Speciation in throughfall [PDF]

, 2010
Trace Metal (TM: Cd, Cu, Ni, Pb, Sb and Zn) atmospheric inputs have been studied on six forested sites. In order to evaluate canopy interaction with atmospheric inputs, TM have been measured in both Open Field Precipitation (OFP) and Throughfall (TF ...

Technical note: Performing LR calculations when loci are missing between reference and trace DNA profiles

Forensic Science International: Reports, 2022
The initial version of DNAStatistX calculated likelihood ratios (LRs) using only loci present in both the trace and reference profiles, thereby ignoring loci from the trace that are not present in the reference.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Applications of geoforensic trace evidence [PDF]

Geoforensic trace evidence studies can be crucial for law enforcement and civil/criminal prosecution and defence, to test potential links between suspect(s), crime scenes or forensic object(s).

Microscopic and spectrometric characterizations of trace evidence materials present on the discharged lead bullet and shot—A case report

Journal of Saudi Chemical Society, 2010
Adherence of target materials or those present on the trajectory of the fired projectile is most common in the offences involving the use of firearms. The recovery and identification of such adhering materials from a projectile may identify the origin or

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

Molecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Trace element and isotope constraints on crustal anatexis by upwelling mantle melts in the North Atlantic Igneous Province: an example form the Isle of Rum, NW Scotland [PDF]

, 2009
Sr and Nd isotope ratios, together with lithophile trace elements, have been measured in a representative set of igneous rocks and Lewisian gneisses from the Isle of Rum in order to unravel the petrogenesis of the felsic rocks that erupted in the early ...
