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

European 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.

Monochorionic Diamniotic Twins with Sex Discordance: Case Series [PDF]

Diagnostics
Background and Clinical Significance: Ultrasonographic diagnosis of twin pregnancies has become routine, with chorionicity playing a crucial role in assessing associated risks. Traditionally, monochorionic (MC) twins were believed to derive from a single

The Impact of Environmental and Genetic Factors on Bone Quality in Monozygotic and Dizygotic Twins

Biomedicines, 2022
The purpose of the research was to assess the genetic and environmental influences on bone properties. One hundred thirty-two pairs of twins (99/33 monozygotic/dizygotic) underwent anthropometric measurements and phalangeal quantitative ultrasound (DBM ...

Dizygotic twinning [PDF]

Human Reproduction Update, 2007
The tendency to conceive spontaneous dizygotic (DZ) twins is a complex trait with important contributions from both environmental factors and genetic disposition. Twins are relatively common and occur on average 13 times per 1000 maternities, though the twinning frequency varies over time and geographic location.

Genetic modelling of dizygotic twinning in pedigrees of spontaneous dizygotic twins [PDF]

American Journal of Medical Genetics, 1996
The inheritance of spontaneous dizygotic (DZ) twinning was investigated in 1,422 three-generation pedigrees ascertained through mothers of spontaneous DZ proband twins. DZ twinning was modelled as a trait expressed only in women. The penetrance was modelled first as a parity independent and secondly as parity dependent.

Fathering of dizygotic twins and risk of prostate cancer: nationwide, population-based case-control study. [PDF]

PLoS ONE, 2014
BACKGROUND: An association between male fertility and risk of prostate cancer has been suggested, possibly through lower androgen levels in subfertile men.

Indian twin registry: A gold mine for genetic studies

Asian Journal of Medical Sciences, 2023
Twins are a source of curiosity, both for the family and the scientific community. Genetic similarities between twins have been the preferred choice to study the heritability of traits.

Urticaria in Monozygotic and Dizygotic Twins [PDF]

Journal of Allergy, 2012
Aim. To identify risk factors for urticaria, to determine the relative proportion of the susceptibility to urticaria that is due to genetic factors in an adult clinical twin sample, and to further determine whether the genetic susceptibility to urticaria overlaps with the genetic susceptibility to atopic diseases. Methods.

Gastritis Stages in Monozygotic and Dizygotic Dyspeptic Twins

Gastroenterology Research and Practice, 2020
Background. The progression of Helicobacter pylori-associated gastritis towards atrophic gastritis is modulated by host-related and environmental factors.

Rare spontaneous monochorionic dizygotic twins: a case report and a systematic review

BMC Pregnancy and Childbirth, 2022
Background Monochorionic dizygotic twins are a rare condition, mostly related to assisted reproductive technology. This type of twinning is burdened by the same risk of pregnancy complications found in monochorionic monozygotic pregnancies.
