The determination of the postmortem interval is of utmost importance in medicolegal death investigations. There are a number of ways to estimate the postmortem interval; however, the current established methods are susceptible to numerous biotic and abiotic factors. Previously published studies state that protein concentrations in postmortem brain tissues can detect protein changes via immunoblotting and densitometry techniques. The objective of the current study was to determine if there is a correlation between protein expression in cadaver tissues and postmortem interval. To this end, 18 brain tissues from cadavers from criminal cases were examined to determine how many hours after death the presence of four proteins (i.e., talin, α-enolase, cofilin-1, and vinculin) are detectable. Talin protein levels steadily decreased with increasing postmortem interval. Interestingly, the study demonstrated that talin protein levels were statistical significant between postmortem intervals of 24 versus 48 h and 24 versus 72 h by ANOVA. These results provide strong evidence that talin has potential to be used as a unique biomarker for the establishment of an additional method to estimate the time of death.
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 15 November 2016.
All research outputs
#28,747,015
of 34,517,649 outputs
Outputs from Journal of Forensic & Legal Medicine
#975
of 1,308 outputs
Outputs of similar age
#270,828
of 337,774 outputs
Outputs of similar age from Journal of Forensic & Legal Medicine
#10
of 18 outputs
Altmetric has tracked 34,517,649 research outputs across all sources so far. This one is in the 9th percentile – i.e., 9% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,308 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 10.3. This one is in the 14th percentile – i.e., 14% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 337,774 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 10th percentile – i.e., 10% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 18 others from the same source and published within six weeks on either side of this one. This one is in the 38th percentile – i.e., 38% of its contemporaries scored the same or lower than it.
