Genetic and Environmental Contributions to Serological Biomarkers of Extracellular Matrix Remodeling in Asthma: A Twin Study. [PDF]

Clin Transl Allergy
ABSTRACT Background Asthma is characterized by airway obstruction driven by chronic inflammation, leading to extracellular matrix (ECM) remodeling. This involves ECM alterations, including increased collagen deposition and elastolysis, resulting in airway wall thickening and irreversible airflow limitation. Despite ECM remodeling's known role in asthma,

Handedness in twins: meta-analyses

BMC Psychology, 2022
Background In the general population, 10.6% of people favor their left hand over the right for motor tasks. Previous research suggests higher prevalence of atypical (left-, mixed-, or non-right-) handedness in (i) twins compared to singletons, and in (ii)

Confined Blood Chimerism in Monochorionic Dizygotic Twins Conceived Spontaneously

American Journal of Perinatology Reports, 2013
Traditionally, monochorionicity has been regarded as synonymous with monozygosity. However, several recent cases of monochorionic dizygotic twins have shown that monochorionic twins can be dizygous.

Molar incisor hypomineralisation: current knowledge and practice

International Dental Journal, EarlyView., 2020
Background Molar incisor hypomineralisation (MIH) is a common developmental dental condition that presents in childhood. Areas of poorly formed enamel affect one or more first permanent molars and can cause opacities on the anterior teeth. MIH presents a variety of challenges for the dental team as well as functional and social impacts for affected ...

Risk of psychiatric disorders among the surviving twins after a co-twin loss

eLife, 2020
Losing a co-twin by death is a severely stressful event yet with unknown impact on the surviving twin’s risk of psychiatric disorders. We identified all Swedish-born twins who lost a co-twin by death between 1973 and 2013 (n = 4,528), their 4939 non-twin

Discordant phenotypes in twins with infantile nystagmus

Scientific Reports, 2021
Infantile nystagmus (IN) may result from aetiologies including albinism and FRMD7 mutations. IN has low prevalence, and twins with IN are rare. Whilst discordant presentation has been previously reported for IN, we present for the first time the ...

Different sensory dimensions in infancy are associated with separable etiological influences and with autistic traits in toddlerhood. [PDF]

J Child Psychol Psychiatry
Background Infants vary significantly in the way they process and respond to sensory stimuli, and altered sensory processing has been reported among infants later diagnosed with autism. Previous work with adolescents and adults suggests that variability in sensory processing may have a strong genetic basis.

Case Report: Identification of Germline Chimerism in Monochorionic Dizygotic Twins

Frontiers in Genetics, 2021
Monochorionic twins are generally considered to be monozygotic, as monochorionic dizygotic (MCDZ) twins are extremely rare in natural pregnancies. Several studies have reported this rare occurrence, and most of these pregnancies have been conceived by ...

Epigenetic discrimination of Lebanese monozygotic and dizygotic twins: Summarized notes in a single paper [PDF]

International Research Journal of Science, Technology, Education, and Management, 2021
Monozygotic twins’ differentiation is worldwide limited due to the fact that they share the same genotype. For forensic purposes, many studies involving monozygotic twins were accomplished.
