In the contemporary spectroscopy there is a trend to record spectra with the highest possible spectral resolution. This is clearly justified if the spectral features in the spectrum are very narrow (for example infra-red spectra of gas samples). However there is a plethora of samples (in the liquid and especially in the solid form) where there is a natural spectral peak broadening due to collisions and proximity predominately. Additionally there is a number of portable devices (spectrometers) with inherently restricted spectral resolution, spectral range or both, which are extremely useful in some field applications (archaeology, agriculture, food industry, cultural heritage, forensic science)...

BACKGROUND: Orbital index (OI) expresses the proportion of the orbital height to the orbital width and varies with race, regions within the same race and periods in evolution. This index is useful in forensic medicine, anthropology and surgery. However, the average OI among Ghanaian adults was unknown. AIM: The aim of this study was to determine the orbital index of adult Ghanaians and classify them under one of the three predetermined groups. METHOD: The study design was a retrospective cross-sectional...

Mitochondrial DNA (mtDNA) analysis has displayed an important role and been considered as a powerful tool in various fields of forensic science applications. Nowadays, single nucleotide polymorphisms (SNPs) on mtDNA have become additional DNA markers when conventional STR typing practically fails. mtDNA sequencing of polymerase chain reaction (PCR) products from the hypervariable region I (HVRI) and II (HVRII) is the standard method of mtDNA analysis. However, mtDNA sequencing is rather expensive, time consuming and technically complex...

Individual age estimation is a key factor in forensic science analysis that can provide very useful information applicable to criminal, legal, and anthropological investigations. Forensic age inference was initially based on morphological inspection or radiography and only later began to adopt molecular approaches. However, a lack of accuracy or technical problems hampered the introduction of these DNA-based methodologies in casework analysis. A turning point occurred when the epigenetic signature of DNA methylation was observed to gradually change during an individual´s lifespan...

DNA barcodes are widely used in taxonomy, systematics, species identification, food safety, and forensic science. Most of the conventional DNA barcode sequences contain the whole information of a given barcoding gene. Most of the sequence information does not vary and is uninformative for a given group of taxa within a monophylum. We suggest here a method that reduces the amount of noninformative nucleotides in a given barcoding sequence of a major taxon, like the prokaryotes, or eukaryotic animals, plants, or fungi...

In contrast to the well-established and highly accurate morphological methods available for sexing adult skeletons, juvenile sex estimation is widely recognised as a difficult task that faces a series of challenges. The acquisition of 3D data, and construction of 3D models from volume or surface scans, has become increasingly common in forensic sciences, and these data offer considerable opportunity for the development and refinement of methods in sex estimation. The suitability and potential of virtual methods for juvenile sex estimation are evaluated with the aims of identifying (1) the benefits and challenges associated with virtual data and quantitative analysis of 3D models, and (2) pathways that may lead to practical improvements for sexing juveniles...

A recent report by the US President's Council of Advisors on Science and Technology (PCAST), (2016) has made a number of recommendations for the future development of forensic science. Whereas we all agree that there is much need for change, we find that the PCAST report recommendations are founded on serious misunderstandings. We explain the traditional forensic paradigms of match and identification and the more recent foundation of the logical approach to evidence evaluation. This forms the groundwork for exposing many sources of confusion in the PCAST report...

The study of facial growth is explored in many fields of science, including anatomy, genetics, and forensics. In the field of forensics, it acts as a valuable tool for combating child pornography. The present research proposes a new method, based on relative measurements and fixed references of the human face-specifically considering measurements of the diameter of the iris (iris ratio)-for the analysis of facial growth in association with age in children and sub-adults. The experimental sample consisted of digital photographs of 1000 Brazilian subjects, aged between 6 and 22 years, distributed equally by sex and divided into five specific age groups (6, 10, 14, 18, and 22 year olds ± one month)...

CONTEXT: Some authors have proposed that post-mortem drug concentrations in bile are useful in estimating concentrations in blood. Both The International Association of Forensic Toxicologists (TIAFT) and the US Federal Aviation Administration recommend that samples of bile should be obtained in some circumstances. Furthermore, standard toxicological texts compare blood and bile concentrations, implying that concentrations in bile are of forensic value. AIM: To review the evidence on simultaneous measurements of blood and bile drug concentrations reported in the medical literature...

Traumatic axonal injury (TAI) is a progressive and secondary injury following traumatic brain injury (TBI). Despite extensive investigations in the field of forensic science and neurology, no effective methods are available to estimate TAI interval between injury and death. In this study, FTIR spectroscopy with infrared microscopy was applied to collect infrared spectra in the corpus callosum (CC) of rats subjected to TAI at 12, 24 and 72h post-injury versus control animals. The classification among different groups was visualized based on the acquired dataset using hierarchical cluster analysis (HCA) and partial least square (PLS)...

Estimation of total number of neurons in the Spiral Ganglion (SG) at various ages and their functional status is important as these neurons are constantly exposed to noise and other environmental factors that may lead to neuronal loss with aging due to excitotoxic damage. Parvalbumin (PV) is a calcium-binding protein (CBP), found in highly metabolically active neurons. It helps in buffering cytosolic calcium, which is essential for neurotransmitter release. The neurons in the adult human SG express PV more strongly than other CBPs like calbindin and calretinin...

Kaye N Ballantyne, Gary Edmond, Bryan Found
Peer review features prominently in the forensic sciences. Drawing on recent research and studies, this article examines different types of peer review, specifically: editorial peer review; peer review by the scientific community; technical and administrative review; and verification (and replication). The article reviews the different meanings of these quite disparate activities and their utility in relation to enhancing performance and reducing error. It explains how forensic practitioners should approach and use peer review, as well as how it should be described in expert reports and oral testimony...
