To preliminarily evaluate the applicability of bacterial DNA as a marker for the forensic identification of vaginal fluid, we developed and performed PCR-based detection of 16S ribosomal RNA genes of Lactobacillus spp. dominating the vagina and of bacterial vaginosis-related bacteria from DNA extracted from body fluids and stains. As a result, 16S ribosomal(More)
We consecutively observed lipid peroxidation and cell membrane damage under the condition of hypoxia-reoxygenation (H/R) in cells and analyzed their mechanisms by using electron transport inhibitors and an antioxidant. In H/R experiments, lipid peroxidation and cell membrane damage were observed during the hypoxia phase. In the reoxygenation phase, lipid(More)
We present two cases in which the ethanol concentration in blood samples taken after death continued to increase in the absence of any remarkable increase in n-propanol concentration. Species of bacteria and yeasts, including Candida albicans were isolated from these samples. We then examined whether C. albicans, the most common yeast in the general(More)
In this study, Tamm-Horsfall protein (THP), a major component of urinary protein, and uroplakin III (UPIII), a transmembrane protein widely regarded as a urothelium-specific marker, were evaluated for forensic identification of urine by ELISA and/or immunohistochemistry. THP was detected in urine, but not in plasma, saliva, semen, vaginal fluid, or sweat by(More)
We discuss the usefulness of postmortem computed tomography (PMCT) by reviewing cases of cervical spine injury. A merit of PMCT is that it can identify injury that cannot be found on autopsy; however, peculiar defects of it may exist. While PMCT can identify bone fractures, it cannot indicate whether the injury was inflicted while the deceased was still(More)
The Japanese method of inquest, which depends mostly on external examinations, may misdiagnose a considerable number of accidental deaths and suicides as death by disease. We conducted computed tomography (CT) scans of 80 cases for which police concluded death by disease or natural causes based on police investigations into the circumstances and results(More)
ABO genotyping is often performed to identify the blood type of decomposed samples, which is difficult to be determined by a serological test. In this study, we developed a simple method for ABO genotyping using a DNA chip. In this method, polymerase chain reaction-amplified and fluorescent-labeled fragments in the ABO gene and primate-specific D17Z1 were(More)
We used a mobile computed tomography (CT) unit for postmortem examinations of deceased subjects to see how many mistakes on cause-of-death diagnoses were made in Japan. In 5 of 20 cases, the cause of death determined by CT was different from the diagnosis made by superficial postmortem examination. In one case, the superficial examination suggested no(More)
Superimposition has been applied to skulls of unidentified skeletonized corpses as a personal identification method. The current method involves layering of a skull and a facial image of a suspected person and thus requires a real skeletonized skull. In this study, we scanned skulls of skeletonized corpses by computed tomography (CT), reconstructed(More)
Postmortem computed tomography (CT) images can show internal findings related to the cause of death, and it can be a useful method for forensic diagnosis. In this study, we scanned a ready-made box by helical CT on 2-mm slices in a mobile CT scanner and measured each side of the box to assess whether reconstructed images are useful for superimposition. The(More)
