Skeletal Remains from Late Roman Period: »As Old as Diocletian\u27s Palace«
In 2000, human skeletal remains were discovered in Split (Croatia). As archaeologists confirmed, it was an ancient skeleton accompanied by ceramics and bracelet characteristic for late Roman period whose possible violent death was excluded. The bone sample was radiocarbon dated by AMS to 1750 years. DNA was successfully extracted from the bone sample and subsequently typed using mt DNA and STR systems. The metal content was determined by atomic absorption spectrometry (AAS) in flame mode. Mercury concentration was determined by direct consecutive measures taken with a mercury analyzer. According to our results, we consider that the bones could belong to the one of the last citizens of the Diocletian’s Palace
Sex estimation of the sternum by automatic image processing of multi-slice computed tomography images in a Croatian population sample: a retrospective study
Aim To determine the sexual dimorphism of the sternum
with standard measurements in a contemporary Croatian
population sample using multi-slice computed tomography
(MSCT) and to compare the data obtained by an automatic
with those obtained by a manual approach.
Methods Five sternal measurements were obtained from
MSCT images of 73 men and 55 women and three sternal
indices were calculated. Custom image analysis software
was developed for automatic segmentation and calculation
of sternal measurements. Measurements of sexual dimorphism
were automatically calculated and compared
with manual measurements. Results All of the sternal measurements exhibited significant
differences between men and women. The discrepancies
between manual and automatic measurements
ranged from 2.8% to 3.6% of the mean average values obtained
with the automatic approach. The most accurate
single-variable discriminant function was sternal body
length (82.8%), the most accurate index was sternal area
(89.1%), and the discriminant function using three variables
was manubrium width, sternal body length, and sternal
body width (90.6%).
Conclusion Sternal measurements are a reliable sex indicator
and can be used in forensic casework. Computer-aided
measurement methods can accelerate sex estimation
and improve its precision and accuracy
