Implantation of an RFID-tag into human molars to reduce hard forensic identification labor. Part 2: physical properties

Modifying and implanting existing RFID-tags into extracted human molars was described previously [P. Thevissen, G. Poelman, B. Puers, M. De Cooman, G. Willems, Implantation of RFID-tag into human molars to reduce hard forensic identification labor. Part 1. Working principle, Forensic Sci. Int. 156 (2006)]. Maximal vertical occlusal load during which the implanted RFID-tags remain active was evaluated in vitro. The temperature dependency of the implanted RFID-tags was studied on the extracted teeth to find out the maximal obtainable temperature before failure and a test with embedded thermistors to verify temperature distributions. The maximal working temperature of the implanted RFID-tags was revealed and gave indications for the set-up of measuring intra oral and intra tooth temperature during the cremation of a human body. Fatigue was induced on the implanted teeth by thermocycling. The results of this investigation showed the need of putting an extra insulating layer around the modified tags before implantation. The different in vitro tests indicated that the implanted RFID-tags can support certain oral and forensic circumstances.     

Repetition or reparation? An exploratory study of the relationship schemas of child molesters in treatment

This exploratory study examined the relationship patterns of child abusers in treatment by comparing interactions involving the therapist with those involving a parent. Twenty participants were included in the study. The participants' relationship patterns were assessed using the core conflictual relationship theme (CCRT) method. Core schemas were found in interactions involving the therapist and a parent. The two CCRTs found in interactions with parents were often motivated by a desire for closeness or intimacy, to which the parent reacted with rejection or domination. The participants then felt disappointed, depressed, and unreceptive. In relationship episodes involving the therapist, a similar desire for closeness was answered with help and cooperation from the therapist, hence leading the participants to feel self-controlled and self-confident. Furthermore, the therapist's criticism and opposition was often experienced as an indication of care and acceptance.     

Psychological health in midlife among women who have ever lived with a violent partner or spouse

This study examines the psychological health correlates of domestic violence in a large random sample of mid-aged Australian women (N = 11,310, age 47 to 52 years). Logistic regressions were used to investigate the associations between domestic violence and depression, anxiety, and psychological wellbeing, after adjusting for demographic variables (marital status, income management, area). Results indicate increased odds of having experienced domestic violence for those who had: ever experienced a diagnosis of depression, anxiety, or an "other" psychiatric disorder; recent symptoms of depression and anxiety; used psychoactive medication for depression or anxiety in the 4 weeks prior to the survey; and who reported current depression. Current psychological well-being had an inverse association with a history of domestic violence: As psychological well-being decreased, the odds of having ever experienced domestic violence increased. The results indicate that a history of domestic violence is associated with decreased psychological well-being in mid-aged Australian women.

人体血液体外电击致血细胞穿孔的扫描电镜观察

目的探讨血细胞体外电击时细胞膜的结构变化。方法对成人血液分别分组通过220V交流电电击5,10,20,30s和1min后,用扫描电镜观察血细胞膜的变化。结果电击后,即可以观察到红细胞与白细胞的细胞膜穿孔,其中红细胞穿孔可为一个或多个,形状多为圆形或卵圆形,白细胞穿孔则为多个,呈筛网状;穿孔细胞数随电击时间延长而增多;电击5s时为6%左右,以后逐渐增加,至电击1min时,穿孔细胞数可达40%左右。结论电流作用可以使血细胞膜发生穿孔,穿孔细胞数随通电时间延长而增多。
