The quality of young children's peer relationships is important for their development, and it assumed that parenting self-regulation skills shape behavior when interacting with peers. In this multi-informant-multi-method study, we examined the direct mediated associations between preschool parenting, behavioral self-regulation, aggression relationship problems in elementary school-aged children...

Adult female cercopithecines have long been known to bias their social behaviour towards close maternal kin. However, much less is understood about the behaviour of paternal kin, especially in wild populations. Here, we show that wild adult female baboons bias their affiliative behaviour towards their adult paternal half-sisters in the same manner and to the same extent that they bias their beh...

Maternal effects are now universally recognised as a form of nongenetic parental influence on offspring but, until recently, paternal effects were regarded as an anomaly. Although it is now clear that paternal effects are both widespread and important, their proximate basis and evolutionary consequences have received little attention and remain poorly understood. In particular, because many pat...

Mitochondrial homoplasmy signifies the existence of identical copies of mitochondrial DNA (mtDNA) and is essential for normal development, as heteroplasmy causes abnormal development and diseases in human. Homoplasmy in many organisms is ensured by maternal mtDNA inheritance through either absence of paternal mtDNA delivery or early elimination of paternal mtDNA. However, whether paternal mtDNA...

Although much has been written about transactional models in the study of parenting practices, relatively few researchers have used this approach to examine how child behavior might be related to parental well-being. This study used latent growth curve modeling to test transactional models of age 2 child noncompliance, parental depressive symptoms, and age 4 internalizing and externalizing beha...

Emotion knowledge in childhood has been shown to predict social functioning and psychological well-being, but relatively little is known about parental factors that influence its development in early childhood. There is some evidence that both parenting behavior and maternal depression are associated with emotion recognition, but previous research has only examined these factors independently. ...

Abstract Background Leukemia is the most prevalent childhood cancer, and Acute Lymphoblastic Leukemia (ALL) constitutes 75% of all cases. Some epidemiological studies have shown a relationship between socioeconomic status (SES) and some childhood cancers. In the present study, an attempt was made to assess socioeconomical status in a case-control study. Materials and Methods In 2010, a c...

BACKGROUND The paternal allele of Ube3a is silenced by imprinting in neurons, and Angelman syndrome (AS) is a disorder arising from a deletion or mutation of the maternal Ube3a allele, which thereby eliminates Ube3a neuronal expression. Sleep disorders such as short sleep duration and increased sleep onset latency are very common in AS. RESULTS We found a unique link between neuronal imprinti...

Long-term rearing of Cynops pyrrhogaster and ensicauda popei confirmed that the longevities two species were longer than 36 years; C. 37 years e. years, respectively. The male was 34 old or older showed reproductive behavior with a conspecific young female successfully bred. paternal relationships between six offspring also genetically proven, indicating retained its fertility at age older.
