Traditional postero-medial ankle approach for Bartonícek type III in Volkmann Fractures: Is it useful?

Introduction: There is evidence that the presence of a posterior malleolus fracture (PMF) worsens the prognosis of ankle fractures, making conservative treatment a poor choice. PMFs include a heterogeneous group of bone injury patterns that are sometimes associated to medial malleolus extensions, as well as fibula fractures or syndesmotic damage. This requires the surgeon to be well-versed in anatomy to choose the appropriate surgical approach.

E93 controls adult differentiation by repressing in .

In , successful development relies on the precise coordination of both spatial and temporal regulatory axes. The temporal axis governs stage-specific identity and developmental transitions through a number of genes, collectively forming the . Among these, Ecdysone inducible protein 93F (E93) serves as the critical determinant for adult specification, but its mechanism of action remains unclear.

Anatomical analysis of the traditional postero-medial approach to the ankle and evaluation of structures at risk.

Introduction: The presence of a fracture of the posterior malleolus gives a poor prognosis for ankle fractures. This study aimed to analyze the anatomical structures at risk in the traditional postero-medial (TPM) approach.

Methods: Of a total of 21 cadaveric pieces, 11 were female and 10 were male; 9 ankles/right foot and 11 ankles/left foot.

Evolution of tissue-specific expression of ancestral genes across vertebrates and insects.

Regulation of gene expression is arguably the main mechanism underlying the phenotypic diversity of tissues within and between species. Here we assembled an extensive transcriptomic dataset covering 8 tissues across 20 bilaterian species and performed analyses using a symmetric phylogeny that allowed the combined and parallel investigation of gene expression evolution between vertebrates and insects. We specifically focused on widely conserved ancestral genes, identifying strong cores of pan-bilaterian tissue-specific genes and even larger groups that diverged to define vertebrate and insect tissues.

A single-cell transposable element atlas of human cell identity.

Single cell RNA sequencing (scRNA-seq) is revolutionizing the study of complex biological systems. However, most sequencing studies overlook the contribution of transposable element (TE) expression to the transcriptome. In both scRNA-seq and bulk tissue RNA sequencing (RNA-seq), quantification of TE expression is challenging due to repetitive sequence content and poorly characterized TE gene models.
