Side effects of steroid use have led to efforts to minimize their use in transplantation. Two corticosteroid-free regimens were compared with a triple immunosuppressive therapy. Data from the original intent-to-treat (ITT) population (153 tacrolimus/basiliximab [Tac/Bas], 151 tacrolimus/MMF [Tac/MMF], and 147 tacrolimus/MMF/steroids [control]) were analyzed in a 12-month follow-up. Percentage of graft survival were 92.8%, 95.4%, and 95.9% (KM estimates 89.9%, 95.3%, 95.9%), percentage of surviving patients were 98.7%, 98.0%, and 100% (KM estimates 95.9%, 92.8%, and 100%). During months 7-12, graft loss occurred in 3 Tac/Bas, 2 Tac/MMF, and zero control patients, patient deaths in 1 Tac/Bas, 2 Tac/MMF, and zero control, and biopsy-proven acute rejection episodes in 4 Tac/Bas, 3 Tac/MMF, and zero control. Mean serum creatinine at month 12 was 141.9 +/- 69.6 muM, 144.0 +/- 82.1 muM, and 134.5 +/- 71.2 muM (ns). New-onset insulin use in previously non-diabetic patients at month 12 was 1/138, 6/127, and 4/126. Patient and graft survival as well as renal function at 12 months were not different between patient groups, despite considerably higher rates of acute rejection occurring within the first six months after transplantation in both steroid-free patient groups. Tac/Bas therapy might offer benefits in terms of a trend for a more favorable cardiovascular risk profile. [less ▲]

In a few years, safe and definitive solutions should be ready to manage large quantities of high-level radioactive waste. Deep geological repository involving a multibarrier system constitutes one of the most promising options to isolate such waste from the human environment. In order to provide reasonable assurance of the waste isolation efficiency, it is essential to understand the behaviour of the confining geomaterials under a variety of environmental conditions. In particular, variations in temperature and humidity are two main critical aspects in the short and medium term (i.e. several thousands of years). To this end, results from a near-to-real scale experiment were studied by means of a thermo-hydro-mechanical (THM) finite element approach including a consistent thermo-plastic constitutive model for unsaturated soils. This enabled a comprehensive understanding of the behaviour of the buffer material (bentonite). [less ▲]

The diversity of the local grapevine varietal set of Tunisia was remarkably noted in areas of Sfax, Kerkhennah, Gabes, Tozeur, Nafta, Degache, Zarzis and Djerba. Some varieties showed requested characteristics at the level of the production quality, its lateness and its fitness to take on tree, and its adaptation to various Tunisian pedoclimatic conditions. In an attempt to explore the genetic diversity of 25 autochthones cultivars of grapevine (Vitis vinifera L.) in South East of Tunisia, the determination of leaves composition on major mineral elements (Na, K, Ca, Mg, Cu, Zn, Fe and Mn) have permitted to appreciate the genetic variability inter-cultivars and its structuring in this collection. Data (PCA plot, cluster analysis) provide that some of these parameters were designed suitable to discriminate significantly few cultivars (ARCz, KORg, BAKz, MGB, BAK, TON, SAKj…). In fact, the recorded differences could be due to sever environmental conditions such as: nature of the soil, culture and climatic conditions, irrigation, salinity, position of leaves on the branches, rootstock etc. [less ▲]

Pure crystalline BaZrO3 powders can be produced by precipitation in highly basic aqueous solution. The influence of several synthesis parameters is studied. At high OH- concentration ([NaOH] = 20 mol/l), it is possible to obtain the well-crystallized stoichiometric perovskite phase at relatively low temperature (similar to 80 degrees C), after a short reaction time (15 min) and without requiring any precaution to avoid the presence of CO2. This synthesis method yields spherical particles, whose size can be controlled by changing the concentration of the Ba + Zr solution. No calcination treatment is necessary since the precipitate is crystalline. Suitable choice of the synthesis parameters ([NaOH] = 20 mol/l, [Ba + Zr] = 1 mol/l, reaction time= 15 min) yields a sub-micron precipitate with excellent densification behaviour. Corrosion tests in BaO-CuO melt show that similar to 98% dense BaZrO3 obtained by sintering at 1650 degrees C for 13 h could be used for crucibles in the synthesis of YBa2Cu3O7 superconducting single crystals.

Carbohydrate-based surfactants (CBS) constitute an attractive class of amphiphilic molecules owing to their structural diversity generating a wide range of properties which could be developed in food and non-food applications. Based on many functional groups of the carbohydrate part, it is possible to design multiple amphiphilic structures of CBS varying in the hydrophilic head groups (mono-, oligo-, or polysaccharides), hydrophobic tail (mono-, di-, tricatenar) but also in the linker/spacer between them. The main structures of CBS include mono- and bicatenar glycolipids, bolaforms, and gemini. Moreover, CBS compounds can be produced from the most abundant renewable materials allowing large product concept possibilities. Among general properties of surfactants, interfacial properties molecules occupy a fundamental key role for colloidal system formulations since they control most of technological aptitudes required for forming and stabilizing food, cosmetic, agrochemical, detergent, and pharmaceutical products. High-throughput methodology applied to screening of CBS interfacial properties appears crucial for achieving optimum formulations of colloidal systems like foams and emulsions for which small amounts of single or mix surface-active agents are often needed and numerous physical and chemical parameters are involved. This general approach may be applied to any amphiphilic molecules produced from other renewable resources of surface-active compounds like micro-organisms and by direct extraction from vegetable materials. One of the key factors for the development of this methodology is the use of automated instrument systems in laboratory scale which are still lacking in this field compared to those existing in the analytical chemistry and biochemistry areas.

OBJECTIVE: Treatment of depression should result in the absence of symptoms, i.e. remission, in order to restore the functional status of the patient and reduce the risk for relapse. The study assessed the current remission rates in primary care and determined the influencing factors. METHODS: 10 consecutive depressive patients treated by antidepressants for at least 3 months and not more than 12 months were screened by each investigator. Remission rates were defined using the Hamilton-Depression scale 7 items (score of 3 or less) as well as the Carroll self rating scale (score of 7 or less). In addition, patients completed the Sheehan Disability Scale (SDS). Initial severity of depression, type of treatment and socio-economic factors were collected. RESULTS: 292 general practitioners screened a total of 2630 patients. Results indicated low remission rates: 28.3% according to the clinician and 17.1% according to the patient. Absence of remission was associated with higher impairment in work, social and family life. The most frequently reported residual symptoms in nonremitters were general somatic symptoms (92%), depressed mood (92%), psychic anxiety (91%) and impaired work and activities (89%). No differences were observed in remission rates between men and women. Remission rates were significantly lower in patients living alone as compared to those living in couple or family (25.1% vs 30.2%, p=0.03), in patients with lower education (21.3% vs 32.3%, p<0.001), in patients speaking French as compared to Dutch (24.0% vs 34.0% p<0.001), and unemployed patients compared to patients having an occupation (17.1% vs 39.0%, p<0.001). Higher initial severity and number of previous episodes decreased remission rates (p<0.001). CONCLUSION: This study shows low remission rates in depressed patients treated in general practice. The absence of remission is associated with impairment in work, social and family life. Special attention should be given to identify patients who do not reach remission. [less ▲]
