HoxA genes exhibit central roles during development and causal mutations have been found in several human syndromes including limb malformation. Despite their importance, information on how these genes are regulated is lacking. Here, we report on the first identification of bona fide transcriptional enhancers controlling HoxA genes in developing limbs and(More)
Limb development relies on an exquisite coordination between growth and patterning, but the underlying mechanisms remain elusive. Anterior-posterior and proximal-distal specification initiates in early limb bud concomitantly with the proliferative expansion of limb cells. Previous studies have shown that limb bud growth initially relies on fibroblast growth(More)
Obstruction of a major bronchus by a benign lesion can be accompanied by a functional reduction of the perfusion of the distal lung. This disorder is reversible after removal of the obstruction. We present 5 cases of obstruction of a main bronchus with functional exclusion of the affected lung on scintigraphy. The obstructing lesion was carcinoid tumour in(More)
In this study, a "green chemistry" approach was developed as an option for remediation of toxic mercury in the environment. Twenty mercury compounds were treated with an environmentally friendly agent cyclodextrin to produce stable non-toxic mercury in soil and water. The binding efficiency was determined using high performance liquid chromatography with(More)
The fin-to-limb transition represents one of the major vertebrate morphological innovations associated with the transition from aquatic to terrestrial life and is an attractive model for gaining insights into the mechanisms of morphological diversity between species. One of the characteristic features of limbs is the presence of digits at their extremities.(More)
Podocytes are specialized kidney cells that form the kidney filtration barrier through the connection of their foot processes. Nephrin and Neph family transmembrane molecules at the surface of podocytes interconnect to form a unique type of cell-cell junction, the slit diaphragm, which acts as a molecular sieve. The cytoplasmic tails of Nephrin and Neph(More)
Resection and anastomosis of the trachea or the tracheal bifurcation, raises numerous problems, which will be discussed in a series of 81 patients: -there is more or less marked ventilatory insufficiency related to the degree of the stenosis, and difficulties of expectoration responsible for retention of sputum; -per-operative ventilation. One must choose(More)
The authors report five cases of benign oesophago-bronchial fistula in adults. These chronic bronchitic patients presented with recurrent episodes of secondary lung infections (or even haemoptysis). Questioning of the patients revealed a history of coughing when swallowing liquids in three cases. Two women concealed this symptom, which was only revealed(More)
