Analytical pyrolysis of Streptococcus saliivarius as and aid to identification in bite-mark investigation

The use of pyrolysis mass spectrometry (Py-MS) and statistical analysis of mass spectra is introduced as a method for “finger-printing” strains of Streptococcus salivarius. The objective is to provide correlative evidence regarding the identity of suspects in cases of assault or rape involving bite-marks. The results of the analysis of isolates from two individuals are presented, illustrating the differentiation of S. salivarius at strain level according to the origin of the isolate.     

Aberrant MN bloodgroup inheritance in a German family: a 'silent' allele?

By means of extensive serogenetic testing of a family, RFLP analysis and biostatistic evaluation we present evidence for the rare transmittance of a 'silent' information at the MN blood group locus in a Caucasian family.     

A new method in criminology: use of ELISA to detect AFP on different materials with monoclonal anti-alpha-fetoprotein

A new method has been introduced to distinguish normal adult serum stains from fetal or newborn serum and amniotic fluid stains with ELISA in cases of criminal abortion and infanticide. The method is based on the sensitive detection of alpha-fetoprotein (AFP) by a two-site enzyme immunoassay (EIA) following its elution with high efficiency from different materials (e.g., cotton, paper, synthetic fabric, or glass) by phosphate-buffered 0.5 M NaCl solution.
