Infancy is a period featuring a high level of intersubject variability but the brain basis for such variability and the potential genetic/environmental contributions remain largely unexplored. The assessment of the brain's functional connectivity during infancy by the resting state functional magnetic resonance imaging (rsfMRI) technique (Biswal et al., 1995) provides a unique means to probe th...

Reversal of Fortune – Re A (Conjoined Twins) and Beyond: Who Should Make Treatment Decisions on Behalf of Young Children?

In the classic twin design, estimation of genetic and environmental effects is based on the assumption that environmental influences are shared to the same extent by monozygotic and dizygotic twins (equal environment assumption, EEA). We explore the conditions in which the EEA can be tested based on multivariate phenotypic data. We focus on the test whether the correlation between shared enviro...

Gene-environment correlation (rGE) exists both within and between families. Between families, accumulating rGE has been used to explain dramatic changes in phenotypic means over time. The Dickens and Flynn model of increases in cognitive ability over generational time, for example, suggests that small changes in phenotype can lead to subsequent reallocation of environmental resources. This proc...

Conjoined twinning is one of the most uncommon congenital anomalies. Maintenance in an intensive care setting during this time allows for close monitoring, stabilisation, and nutritional supplementation of the infants as necessary to optimise preoperative growth and development. The birth of conjoined twins is a very difficult and dramatic moment for parents. It is also a very difficult situati...

Conjoined twins are very rarely seen. We present a case of thoracopagus that was undiagnosed prior to delivery and combined with eclampsia and obstructed labor in a low-resource setting in sub-Saharan Africa. A 27-year-old pregnant woman was presented to the maternity emergency unit of Princess Christian Maternity Hospital (PCMH) in Freetown at term in labor. Upon admission, the patient was awa...

Happiness and Genes Many scientists have argued that they can determine to what extent human happiness levels are controlled by genes by comparing the average happiness levels of identical twins raised apart. If we discover that identical twins raised apart tend to be more hedonically similar than fraternal twins raised apart, this is interpreted as evidence for the thesis that genes have a str...

An important stage in macromolecular crystallography is that of phase extension and refinement when initial phase estimates are available from isomorphous replacement or anomalous scattering or other methods. For this purpose, an alternative method called the twin variables (TwiV) method has been proposed. The algorithm is based on alternately transferring the phase information between the twin...

Eruption of teeth at or immediately after birth is a relatively rare phenomenon. This condition has been the subject of curiosity and study since the time of beginning of beliefs and assumptions. The present case report accentuates the occurrence of neonatal teeth in twins; fraternal twins in particular which is rarest of its kind.
