An optimized protocol based on the DNA IQ™ System has been tested for the extraction of DNA from envelope flaps. DNA is extracted directly without the need for opening and swabbing the flaps. The method is repeatable with <10% R.S.D. (relative standard deviation). The results of a systematic study show that it is an equilibrium extraction, and a small sample volume as well as high lysis buffer content in sample contribute to high extraction efficiency. The extracted DNA requires no further purification steps following its extraction with the DNA IQ™ System. Complete but skewed 15-locus short tandem repeat (STR) profiles, which is typical of degraded of DNA, have been generated from the DNA extracted from 6 to 9 years old casework envelope samples. 相似文献

A method is suggested that allows the use of loci that have shown allelic dropout in kinship analysis as used for disaster victim identification (DVI) and missing person work (MP). This approach uses an extension of a previously published approach to modelling allelic dropout. This method may salvage some information in cases where allelic dropout is hindering DVI or MP work particularly in reconciliations involving a large number of bodies and pedigrees. It should not replace the pursuit of more complete DNA profiles by the normal rework process for such samples. 相似文献

Congestion in trial courts continues to create a dilemma in judicial administration. In Florida, an effort to address this problem in the juvenile justice system emerged with legislative authorization of community arbitration programs. Implementation came in a joint endeavor of a community and a university to develop a juvenile arbitration program. Assessment of the program in reduction of caseload, cost efficiency, recidivism, reduction of delay prior to hearing, and volunteer participation suggests that community arbitration can be a viable alternative. 相似文献

To understand the mortality patterns among drug users and potential risk factors, we evaluated drug‐related deaths reported to the Florida Medical Examiners Commission from 2001 to 2013, by substances, demographics, and manner of death. The annual drug‐related fatalities increased by 57% from 2001 to 2013 (total n = 100,882); 51.8% were accidental, 7.9% homicide, 18.6% natural, and 19.6% suicide. The different manners of death exhibited distinct demographic profiles and drug composition. The gender gap was more prominent in homicide. Age ≥55 years was more closely associated with natural death and suicide. Age <35 years and central nervous system (CNS) stimulants including amphetamines and cocaine showed higher relative risks for accidental death and homicide, whereas CNS depressants including benzodiazepines, carisoprodol, opioids, and zolpidem were more strongly associated with accidental death and/or suicide. The findings aid in identifying populations more vulnerable to drug‐related deaths, developing targeted interventions and thereby improving efficiency of preventive efforts. 相似文献
