Brain Serotonin Transporter Is Elevated in Obesity: Bayesian and Frequentist Meta‐Analyses

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims The brain plays a critical role in controlling energy balance. Previous studies have mainly focused on dopaminergic mechanisms, whereas much less attention has been paid to serotonin during the emergence of overweight and obesity. Therefore, this study investigated the association between serotonin transporter (SERT) availability and ...

The Fertility Pattern of Twins and the General Population Compared: Evidence from Danish Cohorts 1945-64 [PDF]

open access: yes
Twin studies provide an important possibility for demographers to analyze patterns of heritability and to estimate structural models with controls for endowments. These possibilities are increasingly used in the context of fertility and related behaviors.

Learning preference among monozygotic twins: An exploratory study

open access: yes, 2012
Students have preferences for how they receive information. The goal of this pilot study was to discover whether there are differences in learning preferences among monozygotic twins doing similar course work while living together.

Gender differences in like-sex middle-aged twins: an extended network analysis of depressive symptoms, cognitive functions and leisure activities

open access: yesEuropean Psychiatry
Background Depression affects twice as many women as men. Risk factors for depression certainly impact this difference, but their strong interconnectedness challenges the assessment of standalone contributions.

Do Parents Propagate Inequality Among Children? Evidence From Chinese and Swedish Twins

open access: yesInternational Economic Review, EarlyView.
ABSTRACT Economists have long studied how parental behavior shapes within‐family inequality, yet empirical findings remain mixed. Using twins data from China and Sweden, we examine the predominant mechanisms reported in the literature. Parents in both countries invest similarly during childhood.

Monozygotic twins discordant for body stalk anomaly

open access: yes, 2002
We report on two cases of monozygotic twins discordant for body stalk anomaly, diagnosed prenatally in a multicenter ultrasound screening study at 10-14 weeks of gestation.

Anthropometric differences between twins at birth and their association with later cognitive performance

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
Background Past studies indicate significant associations between birth anthropometrics, such as relative birthweight or head circumference, and later cognitive performance. Using twin data, we investigated whether these associations are confounded by genetic and environmental factors.

Discordance in monozygotic Parkinson's disease twins – continuum or dichotomy?

open access: yesAnnals of Clinical and Translational Neurology, 2019
Differences in concordance rates between monozygotic and dizygotic twin pairs with Parkinson's disease (PD) have been used to estimate genetic influences in PD pathogenesis.

Genetic Susceptibility to Periodontitis

open access: yesJournal 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
