Estimation of postmortem interval based on the spectrophotometric analysis of postmortem lividity

Legal Medicine, 2010
The color of postmortem lividity and control skin in 21 adult cadavers whose postmortem interval was within 72h, was measured by spectrophotometry in order to estimate the postmortem interval, objectively. The L *a *b * system, which has been widely used for the digital expression of skin color, was used and linear regression analysis was performed to ...

Estimation of the postmortem interval by chemical means

The American Journal of Forensic Medicine and Pathology, 1980
The literature is reviewed regarding estimation of the postmortem interval (PMI) by chemical analysis of cadaver fluids. The most useful measurements on blood and CSF are amino nitrogen, nonprotein nitrogen, ammonia, creatine, and inorganic phosphate; these have some value in the early PMI.

Postmortem Changes and Estimating the Postmortem Interval

2017
Knowledge of the postmortem chemical and physical processes and the factors that affect them will permit the accurate interpretation of gross and microscopic pathology at necropsy and aid in the estimation of the postmortem interval (PMI). Estimation of the PMI is important in many human and animal death investigations; however, the accuracy in ...

Bioluminescent assay of microbial ATP in postmortem tissues for the estimation of postmortem interval

Journal of Huazhong University of Science and Technology [Medical Sciences], 2009
To study the relationship between changes of microbial ATP in four kinds of murine tissues and the postmortem interval (PMI), healthy SD rats were sacrificed and their muscles, livers, spleens and kidneys were sampled at different postmortem intervals.

Toward a universal equation to estimate postmortem interval

Forensic Science International, 2017
Estimating postmortem interval is an important goal in medicolegal death investigations. Although several methods have been developed to achieve this goal, many of these require significant time and advanced expertise to generate a reliable estimate. Unfortunately these techniques do not provide much insight during the early stages of an investigation ...

Comparison of Chemical Methods for Determining Postmortem Interval

Journal of Forensic Sciences, 1989
Abstract Accurate determination of postmortem interval (PMI) is a problem for the forensic thanatologist, especially in unwitnessed deaths. A number of objective chemical methods for determining PMI have been developed, the most widely used being accumulation of potassium in the vitreous humor.

Determination of Postmortem Interval by Sampling Vitreous Humour

The American Journal of Forensic Medicine and Pathology, 1997
Estimation of postmortem interval (PMI) by analyses of vitreous humor has certain advantages over analyses of blood and cerebrospinal fluid (CSF). Certain substances, including potassium and hypoxanthine (Hx), have been shown to exhibit postmortem increase in concentration in vitreous humor in a linear fashion.

Bioelectrical Impedance as a Technique for Estimating Postmortem Interval,,

Journal of Forensic Sciences, 2017
AbstractEstimation of postmortem interval (PMI) is a critical component of death investigation. A cadaver can be hypothesized to be a resistor–capacitor (RC) circuit the impedance (Z) of which changes in a quantifiable manner as the cadaver decomposes. This hypothesis was tested using bioelectrical impedance analysis (BIA) equipment to apply a current ...
