The pore texture of carbon materials obtained from evaporative drying and pyrolysis of resorcinol-formaldehyde aqueous gels is controlled by the initial pH of the precursors solution. In order to produce transition metal-containing carbons with tailored texture, various metallic salts were dissolved in the precursors solution. When necessary, a complexing agent (HEDTA or DTPA) was added to render the metal ions soluble. Ni, Fe and I'd loaded carbon xerogels were synthesized and their pore texture was studied after evaporative drying and after pyrolysis. The carbon texture was also studied with regard to the nature of the metal and the amount of complexing agent. The solubilization of transition metal salts in the resorcinol-formaldehyde aqueous solution does not prevent the texture regulation, even though this texture control is influenced: the limits of the pH interval leading to micro mesoporous carbon materials can slightly differ when a metal salt and/or a complexing agent are added. The pH range shift depends mainly on the amount and nature of the complexing agent, but also slightly on the nature of the metal ion. Nevertheless, the metal particles obtained are rather big (diameter > 15 nm). For catalytic applications, the metal dispersion must be enhanced, especially in the case of expensive metals.

The critical bacterial colonizaion of leg ulcers can impair their healing rate, aggravate the patient discomfort and increase the medical and nursing costs. In recent times, the dressings designed for leg ulcers have followed a pace of conceptual revolution. Some of them are now offered containing an antiseptic of the silver salt family. The silver concentraton delivered into the wound bed is important to consider when assessing treatment efficacy. The diversity of the silver-based dressings currently on the European market is as large as their differences in activity. Only a minority of these dressings adequately control the wound biocenosis. Their cost which is high for the patient, must be compared to that of nursing care that may become less important. The expected beneficit is a reduction in healing time. [less ▲]

Il est commun de considérer que les études en éducation physique conduisent exclusivement à une carrière dans l’enseignement. Toutefois, les recherches portant sur les aspirations professionnelles des étudiants entrant dans ce type de formation sont relativement rares et il n’est pas possible actuellement de déterminer si tous les étudiants possèdent réellement cette vocation «pédagogique». En Communauté française de Belgique, la présence et le succès de 12 établissements de formation en éducation physique a incité le Ministère de l’Enseignement supérieur et de la Recherche scientifique à commander une étude portant sur les motivations des jeunes qui s’engagent dans cette orientation de formation.

Purpose: To assess the patterns of failure in the treatment of early-stage squamous cell carcinoma of the glottic larynx. Patients and Methods: Between 1983–2000, 122 consecutive patients treated for early laryngeal cancer (UICC T1N0 and T2N0) by radical radiation therapy (RT) were retrospectively studied. Male-to-female ratio was 106 : 16, and median age 62 years (35–92 years). There were 68 patients with T1a, 18 with T1b, and 36 with T2 tumors. Diagnosis was made by biopsy in 104 patients, and by laser vaporization or stripping in 18. Treatment planning consisted of three-dimensional (3-D) conformal RT in 49 (40%) patients including nine patients irradiated using arytenoid protection. A median dose of 70 Gy (60–74 Gy) was given (2 Gy/fraction) over a median period of 46 days (21–79 days). Median follow-up period was 85 months. Results: The 5-year overall, cancer-specific, and disease-free survival amounted to 80%, 94%, and 70%, respectively. 5-year local control was 83%. Median time to local recurrence in 19 patients was 13 months (5–58 months). Salvage treatment consisted of surgery in 17 patients (one patient refused salvage and one was inoperable; total laryngectomy in eleven, and partial laryngectomy or cordectomy in six patients). Six patients died because of laryngeal cancer. Univariate analyses revealed that prognostic factors negatively influencing local control were anterior commissure extension, arytenoid protection, and total RT dose < 66 Gy. Among the factors analyzed, multivariate analysis (Cox model) demonstrated that anterior commissure extension, arytenoid protection, and male gender were the worst independent prognostic factors in terms of local control. Conclusion: For early-stage laryngeal cancer, outcome after RT is excellent. In case of anterior commissure extension, surgery or higher RT doses are warranted. Because of a high relapse risk, arytenoid protection should not be attempted. [less ▲]
