[Show abstract][Hide abstract]ABSTRACT: To prove the feasibility of detecting menstrual blood as well as its cellular localization with rabbit-anti-human matrix metalloproteinase-11 (MMP-11) polyclonal antibody.
MMP-11 in menstrual blood, peripheral blood, vaginal liquid, aged menstrual bloodstain, and endometrium sections were assayed with SAP immunohistochemistry.
MMP-11 was found only in menstrual samples within stroma and epithelium cells.
MMP-11 polyclonal antibody may be applied in the distinction between menstrual blood and venous blood.
[Show abstract][Hide abstract]ABSTRACT: To explore the differences in Haversian system between human and animal bones through imaging analysis and morphology description.
Thirty-five slices grinding from human being as well as dog, pig, cow and sheep bones were observed to compare their structure, then were analysed with the researchful microscope.
Plexiform bone or oeston band was not found in human bones; There were significant differences in the shape, size, location, density of Haversian system, between human and animal bones. The amount of Haversian lamella and diameter of central canal in human were the biggest; Significant differences in the central canal diameter and total area percentage between human and animal bones were shown by imaging analysis.
(1) Plexiform bone and osteon band could be the exclusive index in human bone; (2) There were significant differences in the structure of Haversian system between human and animal bones; (3) The percentage of central canals total area was valuable in species identification through imaging analysis.
[Show abstract][Hide abstract]ABSTRACT: The identification of menstrual blood belongs to the forensic examination of bloodstains. The traditional methods for detecting menstrual blood were reviewed and their obstacles in forensic application were discussed. Matrix metalloproteinase-11 is a kind of protease which degrades the extracellular matrix. Some researches had indicated that matrix metalloproteinase-11 might be a new marker for specifically and sensitively detecting menstrual blood. The structure, function of matrix metalloproteinase-11 and its application in menstrual blood identification were reviewed.
