Forensische Anthropologie im 21. Jahrhundert

Post-mortem interval estimation of human skeletal remains by micro-computed tomography, mid-infrared microscopic imaging and energy dispersive X-ray mapping

“…[8][9][10] Methods of the PMI estimation of human skeletal remains mainly include histological examination, [11][12][13] reaction with mineral acids, reaction with benzidine, nitrogen loss, 14 amino acid content of proteins, serological protein determination, 15,16 degradation of lipids, remnants of fat-transgression, 17 UV-uorescence, radiocarbon methods, 18 strontium-90 content, 19 luminol chemiluminescence reaction, 3,20 X-ray diffraction (XRD), 21 nuclear magnetic resonance, electron spin resonance, infrared (IR), [22][23][24][25][26][27] and Raman spectroscopy. 28,29 Technical innovations, such as modern radiological procedures, 30 radioisotopic techniques, 31,32 IR spectroscopy 27 and forensic DNA analysis, 33,34 have now opened up numerous new possibilities in the eld of forensic anthropology. Still, there is a need for tools for a rapid and more accurate estimation of the PMI.…”

“…Ganz gleich, welche Methoden verwendet werden, sind antemortale Vergleichsdaten bzw. Vergleichsmaterial von einer möglichen infrage kommenden Person notwendig [22]. Trotz der vorhandenen Möglichkeiten ist die Zuordnung von menschlichen Überresten zu einer bestimmten Person stark eingeschränkt, sobald deren Daten in keiner polizeilichen oder medizinischen Datenbank vorhanden sind.…”

Post-Mortem Interval of Human Skeletal Remains Estimated with Handheld NIR Spectrometry

“…Several studies focus on bones’ chemical and physical changes after death and the varied factors affecting the diagenetic process [ 16 , 17 , 18 ]. So far, techniques applied to determine the time elapsed since death of skeletal remains include histological examination [ 19 , 20 , 21 ], reaction with a mineral acid, reaction with benzidine, nitrogen loss [ 22 ], proteomics [ 23 , 24 , 25 , 26 ], metabarcoding [ 27 , 28 ], degradation of lipids, remnants of fat-transgression [ 29 ], high performance liquid chromatography–tandem mass spectrometry [ 30 ], UV-Vis spectroscopic methods [ 11 , 31 , 32 , 33 , 34 ], radioisotope measurements [ 27 , 35 , 36 , 37 ], luminol chemiluminescent reaction [ 3 , 36 , 38 , 39 , 40 ], X-ray diffraction [ 10 , 41 , 42 ], micro-computed tomography [ 42 ], and infrared (IR) spectroscopy [ 4 , 8 , 9 , 33 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 ]. Some of these methods are destructive, others lack objectivity.…”
