Preverbal Language Abilities in Monozygotic and Dizygotic Twins [PDF]

, 2007
This study examined prelinguistic language development of twins by delineating: differences from developmental expectations; twin-twin communication and twin-mother communication differences; and monozygotic-dizygotic differences.

The etiology of the association between parental nurturance and youth antisocial behavior: Evidence from a twin differences study

JCPP Advances, EarlyView.
Abstract Background Lower parental nurturance is consistently associated with higher levels of youth antisocial behavior (ASB), but the etiology of this association remains unclear. To fill this gap, we employed a twin differences approach to illuminate the environmental and genetic origins of the association between parental nurturance and children's ...

Deformation behaviour of body centered cubic iron nanopillars containing coherent twin boundaries [PDF]

Philosophical Magazine 96 (2016) 3502-3523, 2016
Molecular dynamics simulations were performed to understand the role of twin boundaries on deformation behaviour of body-centred cubic (BCC) iron (Fe) nanopillars. The twin boundaries varying from one to five providing twin boundary spacing in the range 8.5 - 2.8 nm were introduced perpendicular to the loading direction.

Genetic and environmental influences on eating behavior - a study of twin pairs reared apart or reared together [PDF]

, 2012
This study examined the relative influence of genetic versus environmental factors on specific aspects of eating behavior. Adult monozygotic twins (22 pairs and 3 singleton reared apart, 38 pairs and 9 singleton reared together, age 18-76 years, BMI 17 ...

Narcolepsy with cataplexy in monozygotic twins

Sleep Science, 2014
Introduction: This paper describes narcolepsy with cataplexy in two monozygotic twin sisters. Objective: To clinically illustrate the involvement of neurological, genetic and immunologic systems in narcolepsy. Material and methods: We performed a restropective study of these patients that were followed in the sleep medicine ambulatory clinic of the ...

Do the early social environment and persistent peripartum depressive symptoms shape toddlers' expressive language?

JCPP Advances, EarlyView.
Abstract Background Extensive research suggests that peripartum depression is a risk factor for children's early language development. Yet, previous research on this association shows mixed results, often lacking information on the persistence of depression and the social context.

Changes in Gene Sequence that Cause Discordances Involving Disease in Monozygotic Twins [PDF]

, 2021
Identical twins or, monozygotic twins, occur when the egg in a mother is fertilized, but one zygote divides into two separate embryos. Monozygotic twins are considered to be genetically identical, but most twins often display discordances, some involving

Journal of the American Medical Association (JAMA), 2016
IMPORTANCE Estimates of familial cancer risk from population-based studies are essential components of cancer risk prediction. OBJECTIVE To estimate familial risk and heritability of cancer types in a large twin cohort.

Intergenerational transmission of attachment: The role of intelligence

JCPP Advances, EarlyView.
Attachment and cognitive development are associated, but the direction of the association is unclear. Recently, Del Giudice and Haltigan have argued that attachment in childhood and attachment representations in adulthood are influenced by the cognitive capabilities of the individual, which might make the intergenerational transmission of attachment ...

Brain Imaging Phenotypes Associated with Polygenic Risk for Essential Tremor

Movement Disorders, EarlyView.
Abstract Essential tremor (ET) is a common movement disorder with a strong genetic basis. Magnetic resonance imaging (MRI), particularly diffusion‐weighted MRI (dMRI) and T1 MRI, have been used to identify brain abnormalities of ET patients. However, the mechanisms by which genetic risk affects the brain to render individuals vulnerable to ET remain ...
