Background: Venous anatomy of the digits and the hand is poorly reported in the literature compared to arterial anatomy. While knowledge of the venous anatomy is crucial to ensure safe skin incisions, skin flap design, or blood return restoration for digital replantations, data in anatomical and clinical textbooks are rather limited. The purpose of this anatomical study was to describe the venous anatomy of the digits and the hand.

Improvement of our knowledge in this field could lead to better development of animal models for both pedagogical purposes and surgical experimentation. The objective of this comparative study was to describe the descriptive anatomy of the inferior epigastric, subscapular and internal thoracic pedicles in three domestic mammals commonly used as animal models for experimentation.

Phylogeny seems to give the most relevant and plausible explanation of this anatomical variant as a remnant of the panniculus carnosus. However, authors are not unanimous about its origin.

Article Synopsis
- Vascular plants are crucial for Earth's biomass and food supply, but the molecular changes that allowed their conductive tissues to develop are not fully understood.
- This study uncovers the evolutionary path of the TMO5/LHW transcription factor complex, which is essential for the proliferation of vascular cells, showing that both factors have ancient origins.
- The research indicates that TMO5's modern function and the necessity for LHW to form heterodimers arose at the origin of land plants, highlighting that the capacity for vascular cell division played a key role in the evolution of vascular plants.
Background: The national ranking examination (NRE) marks the end of the second cycle (6th university year) of French medical studies and ranks students allowing them to choose their specialty and city of residency. We studied the potential predictive factors of success at the 2015 NRE by students attending a French School of Medicine.
Methods: From March 2016 to March 2017, a retrospective study of factors associated with the 2015 NRE success was conducted and enrolled 242 students who attended their sixth year at the school of medicine of Reims.
