Estimation of the post-mortem interval in beagle dogs
Science & Justice, 2007Estimation of the time that has elapsed between death and the post-mortem examination of a body contributes to the investigation of death by defining the period during which death may have occurred. In a veterinary context, investigations involve a range of incidents including out-of-season shooting of game animals, poaching, death during ...

Metabolomics of post-mortem blood: identifying potential markers of post-mortem interval
Metabolomics, 2014Death results in changes in some metabolites in body tissues due to lack of circulating oxygen, altered enzymatic reactions, cellular degradation, and cessation of anabolic production of metabolites and macromolecules. Metabolic changes may provide chemical markers to better determine the time since death (post-mortem interval), something that is ...

Estimation of the post-mortem interval in human bones by infrared spectroscopy
International Journal of Legal Medicine, 2021In forensic anthropology, there is an inherent difficulty in estimating the post-mortem interval (PMI). This study aimed to assess whether there is a correlation between changes in the bone mineral component and the PMI estimation. Samples of femur and humerus from 80 identified individuals with known post-mortem interval were analyzed.

Predicting the post-mortem interval with machine learning and post-mortem CT radiomics
2023Purpose: Post-mortem CT (PMCT) allows non-invasive whole-body forensic investigation. PMCT images can be used for the extraction of radiomics biomarkers that enable comprehensive tissue characterization.

Estimation of the post-mortem interval using microRNA in the bones
Journal of Forensic and Legal Medicine, 2020MicroRNAs (miRNAs) can be useful in forensic science because of their numerous characteristics, especially stability. Post-mortem interval (PMI) is crucial for death scene investigations. However, estimating PMI is challenging in cases involving significantly decomposed or destroyed bodies, such as those involving skeletonized remains.

Bone Marrow Changes in the Post Mortem Interval
Journal of the Forensic Science Society, 1976The morphology and cytochemistry of the haemopoietic cells in the bone marrow of cadavers were studied at various intervals up to 96 hours after death. Pyknotic erythroblasts, neutrophils and myelocytes showed time-related autolytic changes which gave some indication of the post mortem interval up to 12 hours after death.

The elusive universal post-mortem interval formula
Forensic Science International, 2011The following manuscript details our initial attempt at developing universal post-mortem interval formulas describing human decomposition. These formulas are empirically derived from data collected over the last 20 years from the University of Tennessee's Anthropology Research Facility, in Knoxville, Tennessee, USA. Two formulas were developed (surface

The colour of post-mortem lividity and control skin of 86 cadavers was measured spectrophotometrically to obtain L* (value), a* (chroma) and b* (hue) values. In addition, left heart blood (n = 58), right heart blood (n = 57) and blood from the femoral vein (n = 21) were measured.

Bone citrate content as an indicator of post-mortem interval
Anthropologischer AnzeigerThe citrate levels in the bone start to decrease after death. Therefore, it may be possible to estimate the post-mortem interval if the citrate content decreases at regular and predictable intervals. To verify this, it was used twelve fresh porcine tibiae and femora, fifteen recently buried porcine bones, two samples of human bones curated from the ...

AATF RNome has the potential to define post mortem interval
Forensic Science International, 2015Keeping in view the fact that the circadian rhythm governs human behavioral characteristics, metabolism and body function, the present study was directed to explore whether or not there exists any cooperativity between AATF RNome (comprising AATF mRNA and its encoded microRNA miR-2909) rhythmicity and post mortem interval (PMI).
