A STR mutation in a heteropaternal twin case. 总被引:2,自引:0,他引:2

A heteropaternal male twin case with two men being alleged fathers was investigated as requested by the Court. Up to 37 PCR-based polymorphic DNA systems were studied in this case which was complicated by a paternal ACTBP2 mutation detected in one twin. This is the first report on a STR mutation in a double paternity case where both biological fathers were indisputably identified. The STR systems enable the resolution of these complex genetic relationships even in a case where a mutation in one STR locus was encountered. 相似文献

One hundred and fifty-six teeth were extracted from corpses aged between 15 and 79 years. Of these, 101 teeth were selected for measurement of the mineral content of the root by photon beam absorption. Six or seven cross-sections were measured in each root, and the mean values calculated for the apical, medial, and coronal part within each decade. Further, 20 selected teeth were embedded in methacrylate and the length of the zone of transparency determined in longitudinal sections. There was no significant age dependency of the root's mineral content. There was no correlation between the extent of transparency and the mineral content. 相似文献

The use of the peroxidase-anti-peroxidase (PAP) technique has been described previously for the detection of cellular antigens and in particular ABO antigens from tissue samples (Pedal and Hülle 1984; Pedal and Baedeker 1985; Pedal et al. 1985). In this survey, the PAP method has been employed to study the detection of ABO antigens in cells from body fluids of particular interest to forensic science, namely buccal cells and vaginal cells. Also tested, but in a limited number, were mixtures of body fluids and semen samples. No false reactions were obtained from buccal cells, all samples corresponding to the ABO blood type of the donor. Preliminary results from vaginal cells, vaginal/buccal cell mixtures, and semen were encouraging but must be treated with caution due to the limited number tested. Vaginal smears contaminated with semen showed varying degrees of nonspecificity. 相似文献

Two cases of poisoning with 2-propanol (isopropylalcohol) are reported. In one case, nail polish remover was drunk by a 2-year-old child. The concentration of 2-propanol and its metabolite acetone in the blood could be observed over a period of approximately 50 h. The highest concentration of 2-propanol determined was 4.22 g/l. Acetone reached a maximum value of 2.27 g/l 12 h after ingestion. The child survived without any observable after-effects. In the second case, a 35-year-old man drank ethanol in addition to 2-propanol. The poisoning was lethal. The possible time of intake before death is discussed in relation to the estimated levels of ethanol, 2-propanol and acetone found in the blood and urine. The histomorphological findings are often important as well with regard to time of intake. 相似文献

Due to the suspicion of a gynaecologist, a pathologist was suspected of incorrect diagnoses in cases of breast cancer and the interchanging of tissue samples. Many women applied to the attorney's bureau to clarify the reproaches. The privately owned laboratory for pathology was searched and 926 histological slides, roughly the same number of paraffin blocks and about 20 formalin fixed tissue samples were confiscated. Together with other confiscated material, at least 1236 histological slides and additional 249 paraffin blocks had to be sorted. Histological slides and paraffin blocks were matched with patients as far as possible following the laboratory book. Many of the warranted samples which were diagnosed as containing the carcinoma by the pathologist were missing. A total of 160 samples were chosen and rediagnosed by two independent pathologists. The formalin fixed tissue was negative for DNA most likely due to storage in formalin for years. Most of the histological slides were positive for DNA. On the whole, 18 expertises about histological findings and the DNA results were given. In some cases only DNA results could be presented, as previous experts had only performed DNA examinations without controlling the histological diagnosis. In six cases a carcinoma could be confirmed and the DNA profile matched with patient's DNA; in seven cases a carcinoma was confirmed without match with the patient; in two cases the carcinoma could not be confirmed in the presented samples. A jurisdictional solution was impossible because the accused pathologist died during the investigation. In conclusion, it must be stated that a DNA examination of histological slides should never be performed without a rediagnosis of an independent pathologist and photographic documentation of the findings. Whenever possible, material should be left on the slide. 相似文献

Three car accidents are described in which microtrace analysis was of special significance in the clarification of the seating positions. In all three cases the occupants were under the influence of alcohol. In each case the accident occurred at night and without witnesses. The pattern of injuries in two cases was non-specific. In the first case, no fiber traces were visible to the naked eye; in the other two the fibers were recognizable to the naked eye after close examination. In all three cases, the seating position was ascertained by means of fiber trace analysis. 相似文献
