This article examines sibling influences on adolescent delinquency at age 14, using data from an Australian longitudinal study of 374 same- and mixed-sex sibling pairs. Based on maternal and self-reports, a moderately strong association between siblings' delinquency is found. The relationship remains significant controlling for childhood aggression and family environment factors measured during...

OBJECTIVE To investigate linkage of candidate disease susceptibility genes to rheumatoid arthritis (RA) in affected sibling pair families stratified for specific clinical features. METHOD Two hundred RA affected sibling pair families were genotyped for informative microsatellite markers mapping within or less than 3cM from: INF alpha, INF gamma, INF beta, IL1 alpha, IL1 beta, IL1R, IL2, IL6, ...

Whereas socialization influences in early childhood have been linked to children's emerging internalizing problems and prosocial behavior, relatively few studies have examined how NE might moderate such associations in both advantageous and maladaptive ways. Furthermore, more research is needed to evaluate the impact of sibling relationships as an influential socialization influence on these ch...

Although sibling interactions play an important role in children's early development, they are rarely studied in very young children with an older brother or sister with autism spectrum disorder (ASD). This study used a naturalistic, observational method to compare interactions between 18-month-old infants and their older sibling with ASD (n = 22) with a control group of 18-month-old infants an...

Establishing family relationships, such as parentage and sibling relationships, can be extremely important in biological research, especially in wild species, as they are often key to understanding evolutionary, ecological, and behavioral processes. Because it is often not possible to determine familial relationships from field observations alone, the reconstruction of sibling relationships oft...

Most of the inborn errors of metabolism (IEM) are autosomal recessively inherited and they are more frequent in the countries where consanguineous marriages are commonly practiced. Rarely, more than one IEM are seen in the siblings of one family or in the same sibling. Here we report a patient with both argininosuccinic aciduria (ASA) and methylmalonic acidemia (MMA) and our therapeutic approac...

Each larval hemisegment comprises approximately 30 uniquely specified somatic muscles. These derive from muscle founders that arise as distinct sibling pairs from the division of muscle progenitor cells. We have analyzed the progenitor cell divisions of three mesodermal lineages that generate muscle (and pericardial cell) founders. Our results show that Inscuteable and Numb proteins are localiz...

OBJECTIVE To examine the psychosocial impact of pediatric hematopoietic stem cell transplants (HSCTs) on sibling donors, particularly in unsuccessful HSCTs. METHODS Fifteen sibling HSCT donors, 8 who had participated in successful transplants, and 7 whose recipient sibling died, were interviewed (M age = 19.6 years at time of interviews, and 13.3 years at time of sibling's HSCT). Grounded the...

To address a gap in the literature we examined sibling relationships as context for positive development. Specifically, between individual well-being, closeness, and frequency of communication were explored. The goal this study was to determine whether well-being moderated relationship perceived closeness. Participants included subsample (n = 236) youth from larger who reported having at least ...
