Haplotypes for 12 Y-chromosomal STR loci in a Korean population (the central region)

Haplotypes and allele frequencies of 12 STR loci included in the PowerPlex Y system (DYS391, DYS389I, DYS439, DYS389II, DYS438, DYS437, DYS19, DYS392, DYS393, DYS390, and DYS385a/b) were obtained from a sample of 569 unrelated individuals living in the central region of Korea. A total of 473 haplotypes were observed in the 569 individuals studied, of which 426 (90.06%) were unique. The overall haplotype diversity for the 12 Y-STR loci was 0.9985, and the discrimination capacity was 0.8313. In DYS439, we found a new intermediate-sized allele that added an A at base 3 upstream from the repeat region's first GATA motif. The allele was named 11 (U3Ains) according to its sequence structure.     

Using indirect questions to detect intimate partner violence: the SAFE-T questionnaire

A screening instrument for detecting intimate partner violence (IPV) was developed using indirect questions. The authors identified 5 of 18 items studied that clearly distinguished victims of IPV from a random group of health conference attendees with a sensitivity of 85% and a specificity of 87%. This 5-item instrument (SAFE-T) was then tested on 435 women presenting to three emergency departments and the results compared to a direct question regarding current abuse. The SAFE-T questions detected only 54% of the women who admitted being abused and correctly classified 81% of the women who said they were not victims. The 1-year prevalence of IPV in this sample of women presenting to an emergency department was 11.6%. The authors conclude that indirect questioning of women appears to be more effective at ruling out IPV in an emergency department population and may be less useful for women "early" in an abusive relationship.     

Trends in Psychological/Psychiatric Injury and Law: Continuing Education, Practice Comments, Recommendations

This literature review of the major topics in the field of psychological/psychiatric injury and law is aimed at developing commentary for practice in the area. The field is a fast-developing one, with over ten major topics that it needs to integrate. In particular, the present review focuses current work on: law (evidence, tort); forensic psychology; assessment and testing; psychological injuries (posttraumatic stress disorder, chronic pain, traumatic brain injury, other); the APA DSM-5 draft (Diagnostic and statistical manual of mental disorders; American Psychiatric Association 2010); malingering; causality; multicultural considerations; disability; the American Medical Association (AMA) Guides to the evaluation of permanent impairment (Rondinelli et al. 2008); models; and treatment. At the end of each section of the article, practice comments introduce critical issues in applying the research to psychological work in the area. Whether undertaking tort evaluations, disability, and treatment plan assessments or treating individuals with psychological injuries, the professional needs state-of-the-art information in all the areas listed in order to remain scientifically informed, comprehensive, and impartial. The article concludes with recommendations for an integrated field in psychological/psychiatric injury and law, study in the field, research in its major areas, best practice policies, for example in assessment and treatment, and model building.     

A Rapid,Confirmatory Test for Body Fluid Identification,

We have developed a technique that allows investigators to confirm the presence of blood, semen, and/or saliva in a crime scene sample. It is a confirmatory test where multiple samples can be processed in less than an hour, and it is potentially portable, permitting samples to be processed at the crime scene. Samples at a scene giving a positive result can be further processed while those failing to do so may be ignored. There is a large and growing backlog of DNA evidence in the USA, slowing down the criminal justice system. This backlog has continued to grow despite an increase in the ability to process evidence faster. This technique uses quantum dot molecular beacons to test for tissue‐specific RNA species, identifying particular body fluids. We have demonstrated the tissue specificity of molecular beacons for blood, semen, and saliva.     

Microscopic Age Estimation from the Anterior Cortex of the Femur in Korean Adults*

Abstract: The purpose of this study was to develop age‐predicting equations from the anterior cortex of the femur of Korean adults. Seventy‐two femoral samples (44 male and 28 female) were obtained from Korean cadavers and used to develop the equations. The thin sections (<100‐μm thick) were prepared by manual grinding; the sections were not decalcified and were stained with Villanueva bone stain reagent. Analysis of covariance showed no significant differences in age‐adjusted histomorphological variables between sexes. In stepwise regression analysis, osteon population density, average osteon area, and the most anterior cortical width were selected for an age‐predicting equation which produced a high regression correlation (R² = 0.789). The average Haversian canal area was not significantly related to age for any specimen.
