Social Comparison Orientation in Monozygotic and Dizygotic Twins [PDF]

Twin Research and Human Genetics, 2017
Twin research has offered evidence that monozygotic (MZ) twins are more socially close than dizygotic (DZ) twins, but has not paid much attention to the way twins compare themselves with their co-twin. The few studies in this area suggest that ‘horizontal comparisons’ (social comparison motivated by solidarity or communion with others) matter more for ...

Heritability of cardiac size: an echocardiographic and electrocardiographic study of monozygotic and dizygotic twins.

Circulation, 1985
Because of the uncertainty as to the extent to which cardiac size is determined by exercise training vs genetic endowment, this study investigated familial (genetic plus common family environment) vs nonfamilial influences on cardiac size.

Examining the association between cognitive ability and emotional problems across childhood using a genetically informative design: could there be a causal relationship?

Journal of Child Psychology and Psychiatry, EarlyView.
Background Emotional problems co‐occur with difficulties in verbal and nonverbal cognitive ability, yet the pathways underlying their association remain poorly understood: It is unclear whether effects may be causal, and to what extent they may run from cognition to emotion, or vice versa.

Predicting adolescent disordered eating and behaviours: exploring environmental moderators of polygenic risk

Journal of Child Psychology and Psychiatry, EarlyView.
Background Both genetic and environmental factors contribute to the risk of developing disordered eating, with twin studies demonstrating environmental factors moderate genetic susceptibility. To date, gene–environment interactions leveraging polygenic risk scores (PRS) have not been studied in disordered eating phenotypes beyond anorexia nervosa (AN).

Are Wednesday's Children Full of Woe? Children's Differences in Personality Are Independent of Day of Birth

Journal of Personality, EarlyView.
ABSTRACT Introduction Nursery rhymes, which are rich in literary devices, benefit children's language learning. Less is known about the influence that nursery rhymes' messages may have on children's development. We focused on “Monday's Child,” a popular nursery rhyme that alleges children's day of the week of birth forecasts their differences in ...

Genetic Susceptibility to Periodontitis

Journal of Periodontal Research, EarlyView.
Aim: The aim of this narrative review was to identify genes carrying risk alleles associated with an increased risk of periodontitis and to place them in a biological context. Methods: The literature was reviewed based on predefined criteria. Results: The identified genes largely fall into functions linking immune response with tissue repair. The genes

Primary Progressive Multiple Sclerosis: New Therapeutic Approaches

Neuropsychopharmacology Reports, Volume 45, Issue 3, September 2025.
Primary progressive MS affects 10%–15% of MS patients, causing irreversible neurological impairment. Drugs like ocrelizumab show promise, while high‐dose biotin, simvastatin, and coenzyme Q10 are under investigation. Gene therapy and stem cell treatments also show potential.

Medical demography and epidemiology: dizygotic twins [PDF]

European Journal of Epidemiology, 2009
Demography is the statistical study of populations, epidemiology of health of populations. Fascinating challenges for future research, shared by epidemiology and demography, are to be found in the human life course, how the life course is transmitted over generations, how the healthy life is shaped by dynamics within the life course and how the life ...

An effective encoding of human medical conditions in disease space provides a versatile framework for deciphering disease associations

Quantitative Biology, Volume 13, Issue 3, September 2025.
Abstract It is challenging to identify comorbidity patterns and mechanistically investigate disease associations based on health‐related data that are often sparse, large‐scale, and multimodal. Adopting a systems biology approach, embedding‐based algorithms provide a new perspective to examine diseases under a unified framework by mapping diseases into

Does the sex of one’s co-twin affect height and BMI in adulthood? A study of dizygotic adult twins from 31 cohorts

Biology of Sex Differences, 2017
Background The comparison of traits in twins from opposite-sex (OS) and same-sex (SS) dizygotic twin pairs is considered a proxy measure of prenatal hormone exposure.
