Elderly Algerian women lose their sex-advantage in terms of arterial stiffness and cardiovascular profile.

Objectives: Several studies have shown lower carotid-femoral pulse wave velocity (cfPWV) levels in women compared to men, a difference that could partially explain the increased longevity in women. However, these studies have been performed in industrial countries while few data are available in emerging populations. We studied arterial stiffness, as evaluated by cfPWV, in elderly Algerian men and women.

3D characterization of pores in the cortical bone of human femur in the elderly at different locations as determined by synchrotron micro-computed tomography images.

Unlabelled: Diaphysis, inferior, and lateral superior regions of the femoral neck are subjected to diverse mechanical loads. Using micro-CT based on synchrotron radiation, three-dimensional morphology and connectivity of the pore network are location dependent, underlying different remodeling mechanisms.

Introduction: The three-dimensional (3D) morphology and connectivity of the pore network at various locations in human femurs subjected to diverse mechanical loads were assessed using micro-CT based on synchrotron radiation.

[Value of the use of surgical endoscopy in chest surgery in children].

The authors emphasize the various possibilities of exploration of chest with the mediastinoscope, in a 11 patients series, aiming and reducing surgical parietal approach in infancy, while preserving the feasibility of the procedure. In the thoracic level: beyond the mediastinal approach by the transcervical pathway (mediastinoscopy), the principal application is the pleural cavity access (pleuroscopy) which was performed in seven 3 to 12 years old children. Pleuroscopy was realised through a small intercostal access permitting biopsy with a good visibility (pulmonary biopsy: 4 cases; lateral mediastinal tumor: 2 cases).
