The application of miniplex primer sets in the analysis of degraded DNA from human skeletal remains

A new set of multiplexed PCR primers has been applied to the analysis of human skeletal remains to determine their efficacy in analyzing degraded DNA. These primer sets, known as Miniplexes, produce shorter amplicons (50-280 base pairs (bp)) than standard short tandem repeat (STR) kits, but still utilize the 13 CODIS STR loci, providing results that are searchable on national DNA databases. In this study, a set of 31 different human remains were exposed to a variety of environmental conditions, extracted, and amplified with commercial and Miniplex DNA typing kits. The amplification efficiency of the Miniplex sets was then compared with the Promega PowerPlex 16 system. Sixty-four percent of the samples generated full profiles when amplified with the Miniplexes, while only 16% of the samples generated full profiles with the Powerplex 16 kit. Complete profiles were obtained for 11 of the 12 Miniplex loci with amplicon sizes less than 200 bp. These data suggest smaller PCR amplicons may provide a useful alternative to mitochondrial DNA for anthropological and forensic analysis of degraded DNA from human skeletal remains.     

Effectiveness of state mandates to maintain local government health services for the poor

State governments have used several types of mandates to assure that local governments fulfill state-defined responsibilities, including public health care for the poor. This article reports the findings of a study of procedural public-participation mandates and financial sanctions imposed by California to hold counties to their obligations to provide indigent health care. An inventory of the laws' implementation in all California counties found noncompliance by some counties, although all counties complied after a state Health Services Department unit was established to monitor the counties and provide them with state aid. Case studies in eight counties identified factors that influenced the effectiveness of the laws in modifying or reversing county proposals to close county hospitals or reduce other health services. Policy guidelines are suggested for states that want to develop mandates to enforce indigent-care responsibilities of local governments.
