Abstract Background The syndrome of arachnomelia is an inherited malformation mainly of limbs, back and head in cattle. At present the arachnomelia syndrome has been well known mainly in Brown Swiss cattle. Nevertheless, the arachnomelia syndrome had been observed in the Hessian Simmental population during the decade 1964–1974. Recently, stillborn Simmental calves were observed having a morphology similar to the arachnomelia syndrome. The goal of this work was the characterization of the morphology and genealogy of the syndrome in Simmental to establish the basis for an effective management of the disease. Results The first pathologically confirmed arachnomelia syndrome-cases in the current Simmental population appeared in the year 2005. By 2007, an additional 140 calves with the arachnomelia syndrome were identified. The major pathological findings were malformed bones affecting the head, long bones of the legs and the vertebral column. It could be shown that, with the exception of two cases that were considered as phenocopies, all of the paternal and about two-third of the maternal pedigrees of the affected calves could be traced back to one common founder. Together with the data from experimental matings, the pedigree data support an autosomal recessive mutation being the etiology of the arachnomelia syndrome. The frequency of the mutation in the current population was estimated to be 3.32%. Conclusion We describe the repeated occurrence of the arachnomelia syndrome in Simmental calves. It resembles completely the same defect occurring in the Brown Swiss breed. The mutation became relatively widespread amongst the current population. Therefore, a control system has to be established and it is highly desirable to map the disease and develop a genetic test system.

In times of rapid global and unforeseeable environmental changes, there is an urgent need for a sustainable cattle breeding policy, based on a global view. Most of the indigenous breeds are specialized in a particular habitat or production system but are rapidly disappearing. Thus, they represent an important resource to meet present and future breeding objectives. Based on 105 microsatellites, we obtained thorough information on genetic diversity and population structure of 16 cattle breeds that cover a geographical area from the domestication centre near Anatolia, through the Balkan and alpine regions, to the North-West of Europe. Breeds under strict artificial selection and indigenous breeds under traditional breeding schemes were included. The overall results showed that the genetic diversity is widespread in Busa breeds in the Anatolian and Balkan areas, when compared with the alpine and north-western European breeds. Our results reflect long-term evolutionary and short-term breeding events very well. The regular pattern of allele frequency distribution in the entire cattle population studied clearly suggests conservation of rare alleles by conservation of preferably unselected traditional breeds with large effective population sizes. From a global and long-term conservation genetics point of view, the native and highly variable breeds closer to the domestication centre could serve as valuable sources of genes for future needs, not only for cattle but also for other farm animals.

Objective: the authors' goal in this study was to examine the extent to which having been abused and/or neglected in childhood raises a person's risk for having an adult DSM-III-R diagnosis of antisocial personality disorder., Method: Children who had experienced substantiated child abuse and/or neglect from 1967 to 1971 in a Midwestern metropolitan county area were matched on the basis of age, race, sex, and approximate family social class with a group of nonabused and nonneglected children and followed prospectively into young adulthood. Subjects were located and participated in a 2-hour interview consisting of a series of structured and semistructured questions, rating scales, and a psychiatric assessment using the National Institute of Mental Health Diagnostic Interview Schedule. Interviews were completed with 699 young adult subjects (416 abused and/or neglected and 283 comparison subjects)., Results: Childhood victimization was a significant predictor of the number of lifetime symptoms of antisocial personality disorder and of a diagnosis of antisocial personality disorder, despite the fact that controls for demographic characteristics and arrest history were introduced., Conclusions: These findings suggest the importance of inquiring about a patient's childhood history of abuse and/or neglect when antisocial symptoms are evident. In addition to speculation about a possible saturation model for the consequences of childhood victimization, these findings also reinforce a multiple causation model of antisocial personality disorder.
