Does early life health predict schooling within twin pairs? [PDF]

, 2011
A large number of studies in labor economics estimate the returns to schooling using data on monozygotic twins, under the assumption that educational attainment is random within twin pairs. This exogeneity assumption has been commonly questioned, however,

The host genotype affects the bacterial community in the human gastrointestinal tract [PDF]

, 2001
The gastrointestinal (GI) tract is one of the most complex ecosystems consisting of microbial and host cells. It is suggested that the host genotype, the physiology of the host and environmental factors affect the composition and function of the ...

Differential Neuronal Development in iPSC‐Derived Neural Stem Cells From Monozygotic Twin Cases With Treatment‐Resistant Schizophrenia and Discordant Responses to Clozapine

Neuropsychopharmacology Reports, Volume 46, Issue 2, June 2026.
We investigated early neuronal development using iPSCs from twins with treatment‐resistant schizophrenia discordant for clozapine response. The non‐responder exhibited more pronounced impairment in differentiation than the responder. Transcriptomic analysis revealed distinct developmental gene expression profiles, suggesting that early ...

Chromosome 22q11.2 microdeletion in monozygotic twins with discordant phenotype and deletion size

Molecular Cytogenetics, 2012
We report on a pair of male monozygotic twins with 22q11.2 microdeletion, discordant phenotype and discordant deletion size. The second twin had findings suggestive of DiGeorge syndrome, while the first twin had milder anomalies without any cardiac ...

Earnings Mobility and Origin Dependence: What can twins say together with nonparametric econometrics? [PDF]

This study focuses on earnings immobility and its relation to the originin terms of both the social background and the initial position in the earnings distribution. Twin data is used to reveal the importance for the common background for immobility.

Impact of Positive Lifestyle Behaviors on Direct Health Care Cost Savings for Low Back Pain

Arthritis Care &Research, Volume 78, Issue 4, Page 537-546, April 2026.
Objective This study aimed to investigate the relationship between a previously purpose‐developed lifestyle behavior scale and health care cost savings related to low back pain (LBP). Methods This longitudinal study used data from the Australian Twin Back (AUTBACK) study. LBP and lifestyle behavior measures were collected at baseline. Physical activity

Beyond DNA: Epigenetics and Proteomics in Forensic Science [PDF]

, 2016
The use of genetic evidence in criminal cases is well established and has improved the public opinion and credibility of forensic science. However, several shortcomings associated with current genetic profiling techniques exist. Scientific research aimed

The Brain‐Gut Axis in Parkinson's Disease Pathology

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
Exposure to environmental toxins induces gut dysbiosis, increases intestinal epithelial barrier permeability, immune activation, and oxidative stress, promoting α‐syn misfolding and propagation. Brainstem DMV neurons exhibit α‐syn pathology, dysregulating neuronal excitability and vagal control of GI functions.

Single‐cell‐based non‐invasive screening for fetal pathogenic microimbalances using maternal blood: comparison with invasive prenatal diagnosis

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 4, Page 500-509, April 2026.
ABSTRACT Objective Pathogenic or likely pathogenic copy‐number variants (p/lpCNVs) are a significant cause of perinatal morbidity and mortality. Current prenatal screening based on cell‐free DNA (cfDNA) fails to detect the majority of microimbalances (microdeletions/microduplications), leaving a significant residual risk of undetected chromosomal ...
