Head-tail patterning of the vertebrate embryo: one, two or many unresolved problems?

When, where and how is the head-tail axis of the embryo set up during development? These are such fundamental and intensely studied questions that one might expect them to have been answered long ago. Not so; we still understand very little about the cellu ...

Generation of segment polarity in the paraxial mesoderm of the zebrafish through a T-box-dependent inductive event

Andrew Charles Oates, Laurel Ann Rohde

The first morphological sign of vertebrate postcranial body segmentation is the sequential production from posterior paraxial mesoderm of blocks of cells termed somites. Each of these embryonic structures is polarized along the anterior/posterior axis, a s ...

A dual role for Hox genes in limb anterior-posterior asymmetry

Denis Duboule, Jozsef Zakany

Anterior-to-posterior patterning, the process whereby our digits are differently shaped, is a key aspect of limb development. It depends on the localized expression in posterior limb bud of Sonic hedgehog (Shh) and the morphogenetic potential of its diffus ...

Exploring Curved Anatomic Structures with Surface Sections

Roger Hersch, Sebastian Gerlach, Laurent Saroul

The extraction of planar sections from volume images is the most commonly used technique for inspecting and visualizing anatomic structures. We propose to generalize the concept of planar section to the extraction of curved cross-sections (free form surfac ...

Genetic interaction between Wnt/beta-catenin and BMP receptor signaling during formation of the AER and the dorsal-ventral axis in the limb

By conditional gene ablation in mice, we found that beta-catenin, an essential downstream effector of canonical Wnt signaling, is a key regulator of formation of the apical ectodermal ridge (AER) and of the dorsal-ventral axis of the limbs. By generation o ...

Colored visualization of shape differences between bones

Daniel Thalmann, Sofiane Sarni, Ik Soo Lim

This article addresses visualization of deformation or shape differences between bones while conventional visualization techniques are often about a single bone such as its 3D reconstruction. Given a pair of bones with a set of corresponding anatomical lan ...

Injectable calcium phosphate hydraulic cement (CPHC) used for periodontal tissue regeneration: A study of a dog model

Jacques Lemaître, Pascale Van Landuyt

Injectable calcium phosphate hydraulic cement (CPHC) is a new bone substitute family. This study aimed to evaluate the use of CPHC in surgical periodontitis-simulating defects in a dog model. CPHC was obtained by adding powder mixtures of different calcium ...

Head position during various locomotor executions after prolonged microgravity exposure

Grégoire Courtine

Head orientation in the sagittal plane was assessed before and the second and sixth days after a prolonged microgravity exposure (6 months) in 7 astronauts, which were instructed to execute various locomotor movements (stair ascent, jump down and level wal ...

Noncemented total hip arthroplasty: influence of extramedullary parameters on initial implant stability and on hone-implant interface stresses

Lalaonirina Rakotomanana Ravelonarivo, Pierre-François Leyvraz

Purpose of the study After total hip replacement, the initial stability of the cementless femoral stem is a prerequisite for ensuring bone ingrowth and therefore long term fixation of the stem. For custom made implants, long term success of the replacement ...
