triphalangeal thumb is characterized by the interposition of an extra-phalanx between two normal ones. in this article the authors present the case of a 24-year-old man with bilateral triphalangeal thumb of opposable type, without any other associated anomaly or genetic syndrome. the patient had triangular delta extra-phalanxes that caused ulnar deviation of both thumbs. surgical procedure for ...

This study questions the validity of the principle of a proximo-distal direction of motor development and the idea that distal skill emerges out of and is dependent upon proximal control. To determine the relationship between proximal and distal motor function, 12 normal infants (9 girls, 3 boys), 30-weeks of age, were recorded on videotape while reaching for a one-inch red cube contained in a ...

We would like to commend the authors for their detailed and valuable work. Although various case reports have described postoperative ...

Gene regulation in mammals involves a complex interplay between promoters and distal regulatory elements that function in concert to drive precise spatiotemporal gene expression programs. However, the dynamics of the distal gene regulatory landscape and its function in the transcriptional reprogramming that underlies neurogenesis and neuronal activity remain largely unknown. Here, we performed ...
