Identical unerupted maxillary incisors in monozygotic twins

open access: yes, 2010
Mesiodens is the most common type of supernumerary tooth found in the premaxilla. It might be discovered by the orthodontist by chance on a radiograph or as the cause of an unerupted maxillary central incisor.

Monozygotic twins: Identical or distinguishable for science and law?

open access: yes, 2021
Monozygotic twins, also known as monovular twins, share an identical genetic heritage because they are two individuals who derive from the same zygote. For this reason, they have been considered indistinguishable.

The Returns to Education: A Meta‐Study

open access: yesKyklos, EarlyView.
ABSTRACT There have been many studies estimating the causal effect of an additional year of education on earnings. The majority employ administrative changes in the minimum school‐leaving age as the mechanism allowing identification. Here, we survey 79 such estimates.

Obesity‐Related Coagulation Activation in Adolescents and Children: A Systematic Review and Meta‐Analysis

open access: yesObesity Reviews, EarlyView.
Obesity is widely recognized as a pro‐thrombotic condition, yet the specific biomarker profile reflecting coagulation activation remains incompletely defined. Obesity is associated with increased coagulation activation, particularly in children, suggesting an early pro‐thrombotic shift.

Discordant Hirschsprung's disease in monozygotic twins with concordant congenital deafness

open access: yes, 2000
Discordant Hirschsprung's disease in monozygotic twins is extremely rare. A pair of monozygotic twins with congenital deafness and discordant colonic aganglionosis is presented and genetic and prenatal environmental factors are ...

Low Weight Loss Response to Incretin Analogs: A Systematic Review

open access: yesObesity Reviews, EarlyView.
ABSTRACT The development of GLP‐1 and GIP analogs has been a significant breakthrough in type 2 diabetes and obesity pharmacotherapy. However, individual responses to these medications can vary widely. This systematic review examines factors associated with low or no weight loss response to GLP‐1 and GIP analogs. Key predictors of poor response include

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Mechanism and risk factors for the development of monozygotic twins in mammals [PDF]

open access: yes, 2020
Monozygotic twins result from the splitting of one embryo in early embryonic development. The developmental stage, in which the splitting occurs, is the main factor determining the degree of sharing fetal sacs.

Identifying Genomic Variations in Monozygotic Twins Discordant for Autism Spectrum Disorder Using Whole-Genome Sequencing

open access: yesMolecular Therapy: Nucleic Acids, 2019
Autism spectrum disorder (ASD) presents a set of childhood neurodevelopmental disorders with impairments in social communication and restricted, repetitive, and stereotyped patterns of behavior.

Sex differences in dynamic cerebral autoregulation responses to resistance and endurance training in humans

open access: yesExperimental Physiology, EarlyView.
Abstract Exercise maintains brain health and reduces the risk of cerebrovascular diseases, such as stroke and dementia. The benefits of different ‘modalities’ of exercise on male and female cerebral autoregulation are unclear. In this study, we compared adaptations in dynamic cerebral autoregulation (dCA) during spontaneous and forced oscillations in ...
