Italian population data on two new short tandem repeat loci: D2S1338 and Penta E

A population study on two new short tandem repeat (STR) loci D2S1338 (a tetranucleotide repeat) and Penta E (a pentanucleotide repeat) was performed on 208 unrelated Italian Caucasians. The DNA was amplified by polymerase chain reaction (PCR) and separation and detection of the amplified STR fragments were carried out by use of a PE/ABD PRISM 377 DNA Sequencer 377 automated system (Applied Biosystems Division/Perkin-Elmer). Both loci meet Hardy-Weinberg expectations. There is no evidence for departures from expectations between the two loci. The combined Probability of Discrimination and Probability of Exclusion for the two STR loci are 0.999155 and 0.944925, respectively. The results demonstrate that these two regions can be useful for differentiating among individuals, particularly in concert with other STR loci.     

Review of factors susceptible of influencing post-mortem carbohydrate-deficient transferrin

Seric carbohydrate-deficient transferrin (CDT) is a biochemical marker of chronic alcohol abuse. Assessment of the influence of factors likely to modify CDT concentration is necessary to justify its use in the analysis of post-mortem blood samples. Hemolysis, site of collection and storage were tested. Hemolysed samples showed decreased CDT concentration. Statistical analysis of CDT concentration in cardiac blood versus femoral blood revealed no significant differences. Storage for fifteen days at +4 degrees C or +20 degrees C did not affect CDT concentration but repeated freezing and thawing resulted in decreased levels of CDT.     

Age assessment by rib phase analysis in Turks

The I?can's phase method for the estimation of adult age at death from the sternal extremity of the fourth rib was introduced in 1983. Over the years, numerous tests have confirmed the reliability of this technique on varied samples. However, no large scale study has been conducted to test the application of this method on a modern white sample geographically, genetically, and culturally diverse from the American white database. Therefore, the purpose of this paper is to apply rib phase standards to a Turkish sample to test if the progression of morphological changes follow the same age sequence. Using a sample of 150 males and 144 females of known age at death, each rib was phased using the standards developed by I?can and associates in 1984 and 1985. The phase estimations were then subject to an analysis of variance. The results of the study indicated that Turkish ribs show the same morphological characteristics that define the phases at nearly identical ages. Variation as measured by the standard deviation increased from phase 5 on in both sexes. In conclusion, this study demonstrated that the rib phase standards can be accurately applied to Turks. Investigations of this nature are vital because one cannot assume that a method developed from one group is applicable to a distant population, especially in medicolegal proceedings.     

Dating human skeletal remains: investigating the viability of measuring the equilibrium between 210Po and 210Pb as a means of estimating the post-mortem interval

Estimating the post-mortem interval in skeletal remains is a notoriously difficult task; forensic pathologists often rely heavily upon experience in recognising morphological appearances. Previous techniques have involved measuring physical or chemical changes within the hydroxyapatite matrix, radiocarbon dating and 90Sr dating, though no individual test has been advocated. Within this paper it is proposed that measuring the equilibrium between two naturally occurring radio-isotopes, 210Po and 210Pb, and comparison with post-mortem examination samples would produce a new method of dating human skeletal remains. Possible limitations exist, notably the effect of diagenesis, time limitations and relative cost, though this technique could provide a relatively accurate means of determining the post-mortem interval. It is therefore proposed that a large study be undertaken to provide a calibration scale against which bones uncovered can be dated.     

In- and out-flows of elements in bones embedded in reference soils

Possible exchanges of elements between bone and the surrounding soil after being embedded underground for 2 years were estimated. Bone pieces were samples from human vertebrae without any treatments after resection. Sixteen elements were determined by atomic emission mass spectrometry. These were divided into three types; Type I, an in-flow in which elements increased, as in Fe, Al and Ba; type II, a balanced decrease in which changes were found in S, Mg and Zn; and type III, an out-flow in which elements, such as Ca and P, entered into bones from embedded soils. These exchanges depended on the varying nature of soils and also on the time underground. The exchanges were progressed in duration of the time after burial. Data obtained are possible references to judge the time-lapse after burial of bones in relating to characters of soils embedded, and to identify proper bone elements from containment elements.     

Polymorphism analysis of D6S366 STR locus

The polymorphic STR locus D6S366 was analyzed using PCR and PAG electrophoresis and 7 alleles were detected from 200 unrelated individuals in Wuhan. The allete distribution of the locus was in accordance with Hardy-Weinberg equilibrium. The H, Dp, P, E, and PIC of the D6S366 were calculated in this paper.
