Invariant NKT cells (iNKT cells) recognize glycolipid Ags via an invariant TCR alpha-chain and play a central role in various immune responses. Although human CD4(+) and CD4(-) iNKT cell subsets both produce Th1 cytokines, the CD4(+) subset displays an enhanced ability to secrete Th2 cytokines and shows regulatory activity. We performed an ex vivo analysis of blood, liver, and tumor iNKT cells from patients with hepatocellular carcinoma and metastases from uveal melanoma or colon carcinoma. Frequencies of Valpha24/Vbeta11 iNKT cells were increased in tumors, especially in patients with hepatocellular carcinoma. The proportions of CD4(+), double negative, and CD8alpha(+) iNKT cell subsets in the blood of patients were similar to those of healthy donors. However, we consistently found that the proportion of CD4(+) iNKT cells increased gradually from blood to liver to tumor. Furthermore, CD4(+) iNKT cell clones generated from healthy donors were functionally distinct from their CD4(-) counterparts, exhibiting higher Th2 cytokine production and lower cytolytic activity. Thus, in the tumor microenvironment the iNKT cell repertoire is modified by the enrichment of CD4(+) iNKT cells, a subset able to generate Th2 cytokines that can inhibit the expansion of tumor Ag-specific CD8(+) T cells. Because CD4(+) iNKT cells appear inefficient in tumor defense and may even favor tumor growth and recurrence, novel iNKT-targeted therapies should restore CD4(-) iNKT cells at the tumor site and specifically induce Th1 cytokine production from all iNKT cell subsets.

"MotionMaker (TM)" is a stationary programmable test and training system for the lower limbs developed at the 'Ecole Polytechnique Federale de Lausanne' with the 'Fondation Suisse pour les Cybertheses'.. The system is composed of two robotic orthoses comprising motors and sensors, and a control unit managing the trans-cutaneous electrical muscle stimulation with real-time regulation. The control of the Functional Electrical Stimulation (FES) induced muscle force necessary to mimic natural exercise is ensured by the control unit which receives a continuous input from the position and force sensors mounted on the robot. First results with control subjects showed the feasibility of creating movements by such closed-loop controlled FES induced muscle contractions. To make exercising with the MotionMaker (TM) safe for clinical trials with Spinal Cord Injured (SCI) volunteers, several original safety features have been introduced. The MotionMaker (TM) is able to identify and manage the occurrence of spasms. Fatigue can also be detected and overfatigue during exercise prevented.

O objetivo deste trabalho foi avaliar o crescimento de plantas de café arábica (Coffea arabica) enxertadas sobre café robusta (C. canephora), submetidas a diferentes níveis de reposição de água. O experimento foi realizado em Lavras, MG, em delineamento experimental de blocos ao acaso, em arranjo fatorial 2x2x5, com quatro repetições. Foram feitas avaliações em: duas cultivares de C. arabica - Catuaí IAC-99 e Topázio MG-1190 -, dois tipos de plantas - pé-franco e enxertadas sobre C. canephora 'Apoatã IAC-2258' - e cinco níveis de reposição de água - testemunha sem irrigação e quatro coeficientes de cultura, nos valores 0,2, 0,3, 0,4 e 0,5, do plantio até 24 meses, e 0,4, 0,6, 0,8 e 1,0, de 24 a 29 meses -. Utilizou-se turno de rega fixo, com irrigações às terças e às sextas-feiras. Foram avaliados: altura de plantas, diâmetro de copa e diâmetro de caule. Cafeeiros enxertados têm menor crescimento em comparação aos de pé-franco, no período de implantação da lavoura. A substituição do sistema radicular de C. arabica por C. canephora não altera a resposta das plantas à irrigação.

The Iowa Influenza Surveillance Network (IISN) was established in 2004, though surveillance has been conducted at the Iowa Department of Public Health. Schools and long-term care facilities report data weekly into a Web-based reporting system. Schools report the number of students absent due to illness and the total enrolled. Long-term care facilities report cases of influenza and vaccination status of each case. Both passively report outbreaks of illness, including influenza, to IDPH.

RESUME : But : Décrire l'évolution après traitement de l'arthrite de Lyme dans une zone d'endémie de l'Ouest de la Suisse, région où certains parmi les premiers cas d'arthrite de Lyme en dehors des Etats-Unis (USA) ont été rapportés. Patients et méthodes : Une évaluation rétrospective a été faite à partir d'un groupe de 24 patients (15 H, 9 F; âge moyen :38,7 ans) qui ont présenté une arthrite monoarticulaire (20 cas) ou oligoarticulaire (4 cas) causée par une infection à Borrelia burgdorferi (Bb). Ces patients ont été recrutés par l'intermédiaire de rhumatologues entre 1994 et 1999. Le genou était touché dans 85 % des cas. Une histoire de piqûre de tique était décrite dans 9 cas et un érythème chronique migrant dans 4 cas. Tous les patients avaient un titre d'anticorps pour Bb élevé, dosé par ELISA.Dans 20 cas, un immunoblot était positif pour Bb, la majorité étant positif pour les 3 sous-types de Bb présents en Suisse ; un seul cas était positif pour Bb sensu stricto. Neuf liquides synoviaux ont été examinés par PCR afin de détecter la présence de BbDNA (6 cas positifs). Résultats : Tous les patients ont reçu des antibiotiques soit oralement (10 cas), soit par voie parentérale (14 cas). Une deuxième cure d'antibiotiques a été administrée à 4 patients en raison de persistance de l'arthrite. On a observé une évolution rapidement favorable chez 13 patients et dans 9 cas, il a fallu, pour obtenir la guérison, réaliser une injection intraarticulaire de glucocorticoïdes ou une synoviorthèse. Après une période d'observation de 40 mois en moyenne (de 6 à 84 mois), aucun patient n'a présenté de signe d'arthrite chronique, mais 2 patients se plaignaient encore de myalgies ou d'arthralgies. Conclusion : Nous n'avons pas trouvé dans notre étude d'arthrite récidivante ou chronique après traitement comme on l'a décrit aux USA. Ceci est peut-être lié au fait que les types de Bb observés en Europe sont différents des USA où on trouve seulement Bb sensu stricto. ABSTRACT: Objective: To describe outcomes of treated Lyme arthritis in an endemic area of western Switzerland, where some of the first cases of Lyme disease outside the United States were reported. Patients and methods: We retrospectively studied 24 patients (15 males and nine females, mean age 38.7 years) managed by rheumatologists between 1994 and 1999 for Borrelia burgdotferi arthritis manifesting as monoarthritis (a = 20), oligoarthritis (a = 3), or polyarthritis (a = 1). The knee was affected in 20 (85%) patients. Nine patients reported a history of tick bite and four of erythema chronicum migrans. All the patients but one had a high titer of antibodies to B. burgdoiferi by ELISA and all but two had a positive immunoblot test (22 positive for all three types of B. burgdorferi found in Switzerland and one positive only for B. burgdoiferi sensu stricto). Joint fluid PCR for B. burgdorferi was done in nine patients and was positive in six. Results: All 24 patients received antibiotic therapy, orally (a= 10) or parenterally (n= 14). A second course of antibiotic therapy was used in four patients with persistent arthritis. A rapid response was noted in 13 patients. IntraarticUlar glucocorticoid therapy or a synoviorthesis was required in nine patients. After a mean follow-up of 40 months (range, 6-84 months), none of the patients had chronic arthritis but two reported persistent muscle or joint pain. Conclusion: Recurrent or chronic arthritis, which has been reported in treated patients in the United States, did not occur in our series. This may be ascribable to differences in B. burgdolferi subtypes, as in the United States only B. burgdoiferi sensu stricto is found.
