Les TMS occupent la première place des maladies professionnelles en Tunisie et surtout dans le secteur de câblage dans lequel on constate la présence des mouvements répétitifs dans la majorité des postes du travail.

We consider the second-order gradient-like systemUtt+g(Ut)=∇F(U)(1)whereF:RN→R is analytic andg:RN→RNis Lipschitz and coercive withg(0)=0. We prove the convergence of global and bounded solutions of (1) to some equilibrium points.

We had previously shown that two polypeptides of Plasmodium falciparum are preferentially recognized by antibodies of resistant squirrel monkeys Saimiri sciureus. Free parasites were isolated from synchronized cultures on human erythrocytes initially inoculated with infected Saimiri erythrocytes. Crude extracts were prepared from mature schizont stages and electrophoresed on preparative NaDodSO4/polyacrylamide gels. Two groups of five monkeys were immunized with protein fractions eluted from the 75- and 100-kilodalton regions of the gels. Strong protection against challenge by the homologous strain of P. falciparum was induced in both groups. Analysis of specific anti-malarial antibodies revealed a homogeneous response of all the animals against a few polypeptides of the mature parasite.

We have isolated and sequenced the promoter region of the mouse gene (mOAT) encoding ornithine aminotransferase. A comparison of these mOAT sequences with previously reported sequences for the rat and human genes encoding OAT, rOAT and hOAT, respectively, revealed a 256-bp region flanking the transcription start point that is highly conserved between the three genes. This region contains sequence motifs resembling binding sites for general transcription factors, as well as other trans-acting regulatory proteins.
