Metachromatic Butterfly Bile Pigments for Multi‐Level Optical Security Films
Advanced Functional Materials, EarlyView.Bio‐derived optical security materials are manufactured by embedding butterfly‐based pigments in polymer films. Tunable color and fluorescence responses arise from concentration‐controlled metachromasy, enabling spatially encoded patterns with distinct visible, UV‐active, and spectral signatures.

Multidetector computed tomography (MDCT) has emerged as an effective imaging technique to augment forensic autopsy. Postmortem change and decomposition are always present at autopsy and on postmortem MDCT because they begin to occur immediately upon death. Consequently, postmortem change and decomposition on postmortem MDCT should be recognized and not

Postmortem Changes and Estimating the Postmortem Interval
2017Knowledge 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 ...

Postmortem Changes in Brain Catecholamine Enzymes
Archives of Neurology, 1975Postmortem changes in the activities of tyrosine hydroxylase, dopa decarboxylase, and dopamine-beta-hydroxylase were examined in various areas of rat brain. Tyrosine hydroxylase activity decreased in an exponential fashion with a half-time of two to four hours in caudate-putamen, substantia nigra, and locus ceruleus.

Postmortem Biochemical Changes in Canine Blood
Journal of Forensic Sciences, 1980Abstract Antemortem and postmortem blood samples from 60 dogs were evaluated for sodium, chloride, potassium, urea nitrogen, glucose, creatinine, calcium, phosphorus, total protein, albumin, and carbon dioxide levels. Temperatures were 4, 20, and 37°C Postmortem intervals were 3, 6, 12, 24, and 48 h.

Postmortem Changes in Blood Amitriptyline Concentration
The American Journal of Forensic Medicine and Pathology, 1994Detailed toxicological studies were undertaken on two suicides by amitriptyline overdose, one with salicylate also. In the first case, 10 initial blood samples taken 21 h after body discovery and an estimated 28 1/2 h after overdose had drug concentration (mg/L) ranges of 2.5-12 for amitriptyline (AM), 0.7-3.1 for nortriptyline (NOR), and 81-244 for ...

Changes in Postmortem Identity and Grief
OMEGA - Journal of Death and Dying, 2017This article reviews the concept of postmortem identity, noting its relationships to other concepts such as relational trauma. Identity is a very fluid concept that can change even after an individual's death as new information becomes available or even as social values change.

[Postmortem changes in skin color].
Arkhiv patologii, 1978By the employment of the colorimetric method statistically significant objective data on postmortem changes in the colour of different parts of the skin have first been obtained. Histological and spectrophotometric studies were carried out in order to elucidate the causes of these changes.
