Incidence of GM-system factors in indigenous peoples of Buryatia

Distribution of blood groups by the serum Gm system was studied in Buryats and in the entire population of Buryatia without consideration for the national appurtenance and with consideration for sex. Differences in the incidence of the factors were detected.     

Criminal Decision Making: The Development of Adolescent Judgment,Criminal Responsibility,and Culpability

Theories of judgment in decision making hypothesize that throughout adolescence, judgment is impaired because the development of several psychosocial factors that are presumed to influence decision making lags behind the development of the cognitive capacities that are required to make mature decisions. This study uses an innovative video technique to examine the role of several psychosocial factors—temporal perspective, peer influence, and risk perception—in adolescent criminal decision making. Results based on data collected from 56 adolescents between the ages of 13 and 18 years revealed that detained youth were more likely to think of future-oriented consequences of engaging in the depicted delinquent act and less likely to anticipate pressure from their friends than nondetained youth. Examination of the developmental functions of the psychosocial factors indicates age-based differences on standardized measures of temporal perspective and resistance to peer influence and on measures of the role of risk perception in criminal decision making. Assessments of criminal responsibility and culpability were predicted by age and ethnicity. Implications for punishment in the juvenile justice system are discussed.     

Hypophyseal damage in persons with cerebrocranial injuries and who died in the hospital

The pituitary was examined in patients with craniocerebral injuries who died in hospital in various periods after treatment. Control group consisted of victims died at the site of accident. The results indicate the significance of examining the pituitary in craniocerebral injuries for the diagnosis of thanatogenesis, particularly in patients died in hospital. Causes of traumatic changes in the organ were determined, highly incident in the practice of forensic medical experts: directly during injury, as a result of skull bone fractures; during development of dislocation syndrome and in disorders of blood and lymph circulation in the brain matter; resultant from augmenting traumatic edema of the brain.     

Detecting Deception in Children's Testimony: Factfinders' Abilities to Reach the Truth in Open Court and Closed-Circuit Trials

This study examined the influence of closed-circuit television (CCTV) on jurors' abilities to detect deception in children's testimony. Children ages 7–9 individually played games and made a video movie with a male confederate. In the guilty condition, stickers were placed on exposed body parts (i.e., the child's arm, toes, and bellybutton). In the not-guilty and deception conditions, stickers were placed on the child's clothing rather than on bare skin. Approximately 3 weeks later, mock jurors recruited from the community viewed child participants testify either in a traditional courtroom setting or via one-way CCTV. The mock jurors responded to questions about the child witness and the defendant as well as deliberated to reach a verdict. Children in the deception condition were asked to testify as if the stickers had been placed on exposed body parts rather than on their clothing. Predeliberation, jurors were less likely to convict when a child testified in the deception condition as opposed to the guilty condition. These differences disappeared following deliberation. There was no support for the notion that jurors reach the truth better when children testify in open court versus via CCTV. Implications for jurors' abilities to reach the truth are discussed.     

Clinico-morphological parameters of heroin abuse and pathology connected with it

Morphological manifestations of narcomania in heroin users are described. Diseases associated with heroin narcomania and causes of death of heroin users are presented. Morphological manifestations at the site of injections and inflammatory reactions in parenchymatous organs are characterized. The authors pay special attention to the productive inflammation which can serve as one of the signs that confirm narcomania in cases with parenteral injections of crude heroin. The authors refer the granulomas to toxic allergic form of granulomatous hypersensitive inflammation.     

Glucose and lactate in vitreous humor compared with the determination of fructosamine for the postmortem diagnosis of diabetes mellitus

Diabetes mellitus is a chronic metabolic illness responsible for a great number of deaths. In postmortem diagnosis, because of the difficulty involved in interpreting blood glucose levels and relatively nonspecific pathologic features, biochemical markers in vitreous humor are useful. The aim of this study was to compare the results obtained for the combined determination of lactate and glucose with fructosamine levels recorded in the vitreous humor of two diagnostic groups (one diabetic and the other nondiabetic). The authors intended to ascertain the capacity of different markers measured in vitreous humor to diagnose diabetes mellitus. Fifty-one cadavers (mean age, 58.7 years; standard deviation, 17.09) were studied. The mean postmortem interval was 16.4 hours (standard deviation, 9.05). Cases were assigned to two diagnostic groups according to whether they were previously diagnosed as either diabetic or nondiabetic. Statistically significant differences for glucose, fructosamine, and the sum values of glucose and lactate were found between the two diagnostic groups. The highest levels were obtained in the group of cases with a previous diagnosis of diabetes mellitus. After the comparison of receiver operating characteristic curves, the sum values of glucose and lactate in vitreous humor is a better predictor of antemortem diabetes mellitus than the fructosamine.     

Personal identification using Y-chromosomal short tandem repeats from bodily fluids mixed with semen

The male-specific, human Y-chromosomal short tandem repeats (Y-STRs) are very useful in forensic analysis. The authors report a sexual crime case in which the direct Y-STR haplotype analysis of several mixtures of various bodily fluids including semen was very effective for identifying the perpetrator of the crime. The typing of three Y-STRs (DYS19, DYS389II, and DYS390) could be detected from the mixed DNA of sperm and female cells in the victim's vagina, vaginal orifice, and anus. These haplotypes originated from one man and matched those of the suspect. Accordingly, the combination of direct extraction of DNA and Y-STR haplotype analysis is considered to be very useful for mixtures of bodily fluids, including semen or other male cells.     

Cranial thickness in relation to age, sex and general body build in a Danish forensic sample

The cranial thickness was measured in 64 individuals (43 males, 21 females) autopsied at our institute. The thickness was measured by taking a biopsy with a trephine at four specific locations on the skull. Complete medical records and pathologic autopsy results were available. While none of the individuals had suffered from diseases affecting bone or bone metabolism as such, a large sub group consisted of individuals with a history of, and autopsy finds consistent with, chronic substance and alcohol abuse. There was no statistically significant difference in cranial thickness measures between this group and the rest of the material. Subsequent analyses failed to reveal any correlations between the cranial thickness and sex and age and height and weight of the individual. This is in accordance with most earlier studies, which likewise show no correlation, or only very faint trends, between cranial thickness and these parameters. This study, thus, adds to other studies showing that cranial thickness cannot be used in aging or sexing human remains. Likewise, in a forensic pathological setting, cranial thickness cannot be inferred from the individuals stature and build, which may be an issue in cases of interpersonal violence with cranial trauma.
