The authors report on a case of a dicygotic female twin pair, one of them containing a T/C heteroplasmy in two (heart and brain) of five analysed organs at position nt204 of the HV2 region. Results and especially the evidence of an unequal distribution of the heteroplasmy are discussed. 相似文献

The forensic luminol test is used to screen large areas for the presence of blood. The heme-induced reduction of hydrogen peroxide is coupled to the oxidation of luminol resulting in luminescence. However, photographic documentation of the relatively weak and short-lived luminescence is difficult and luminol is now often replaced by other chemicals. In this study, we investigated reports from the Rostock police department that the addition of "Fit", a dishwashing detergent from former Eastern Germany, could both intensify and prolong the luminescence of luminol on blood stains. Even though this effect was reported only for the original composition of Fit but not the currently sold version, we found that both the old and the new version of Fit increase the brightness of the luminescence while decreasing its duration. This may be due to detergents in the dishwashing liquid, which permeabilize the plasma membrane of the erythrocytes, exposing the Fe3+ inside the cell and speeding up the entire reaction. We did not find any evidence of special ingredients in the old version of Fit that would cause both the increased brightness and prolonged duration of luminescence as reported by the Rostock PD. 相似文献

The study was a cross-sectional examination of African American women positive for intimate partner violence (IPV) who presented to the medical or psychiatric emergency department (ED) for treatment. African American women with a recent history of IPV who presented following an attempted suicide (n = 100) were compared to demographically comparable African American women who were IPV positive who had not attempted suicide and presented for treatment of another condition(n= 100). Women completed face-to-face interviews on several measures, including demographics and the Beck Depression Inventory-II (BDI-II). Overall, there were no demographic differences between cases and controls. Attempters reported statistically significant higher scores on all 21 BDI-II items than did nonattempters. Four BDI-II items had effect size values in the medium range: sadness, self-dislike, suicidal thoughts, and feelings of worthlessness. These four items can be used as a brief screen in the ED to detect female patients positive for IPV at increased risk for suicidal behavior. 相似文献
