HIV-1 latency represents a major hurdle to the complete eradication of the virus from patients under highly active anti-retroviral therapy (HAART) regimens. One solution to this problem would be to eliminate the latently infected cellular reservoirs by forcing gene expression in presence of HAART to prevent spreading of the infection by the newly synthesized viruses. Many studies have reported that a combination of a histone deacetylase inhibitor (HDACi) (i.e. TSA, NaBut, Valproic acid,...) with a pro-inflammatory cytokine (i.e. TNF alpha, IL-1,...) reactivates in a synergistic manner HIV-1 transcription in latently infected cells. The aim of the present study was to determine whether HIV-1 protease inhibitors (PIs) used in HAART (such as Saquinavir, Indinavir, Nelfinavir, Lopinavir, Ritonavir and Amprenavir) could interfere with the potential purge of the cellular reservoirs induced by a combined treatment involving TSA and TNF alpha. We showed, in two HIV-1 latently infected cell lines (ACH-2 and U1) that all PIs efficiently inhibited release of mature viral particles but did neither affect cell apoptosis nor NF-kappa B induction and HIV-1 transcription activation following combined treatment with TNF alpha + TSA. This study is encouraging in the fight against HIV-1 and shows that PIs should be compatible with an inductive adjuvent therapy for latent reservoir reduction/elimination in association with efficient HAART regimens.

Drug-induced immunosuppression is the necessary corollary of organ transplantation. This situation is responsible for an increased risk of both infection and neoplasia. Cutaneous carcinomas are the most frequent malignancies developing after organ transplantation. The usual squamous to basal cell carcinoma ratio is increased and reversed compared to the general population. Carcinomas primarily result from the combination of cumulative sun exposure, fair skin phototype and effects of immunosuppressive drugs. These treatments impair the systemic immunosurveillance and may exert a direct carcinogenic effect. The severity of these carcinomas is due to their multiplicity and to the occurrence of more aggressive lesions. Prevention relies on a strict adherence to sun protection after transplantation, and on refined immunosuppressive strategies. The treatment of the neoplastic lesions is based on their early and complete excision with histological control of the nature of the neoplasm, the safety surgical margins, and the determination of prognostic factors.

In this paper, the question of existence of a natural and projectively equivariant symbol calculus is analysed using the theory of projective Cartan connections. A close relationship is established between the existence of such a natural symbol calculus and the existence of an sl(m+1,R)-equivariant calculus over R^m . Moreover, it is shown that the formulae that hold in the non-critical situations over R^m for the sl(m+1,R)-equivariant calculus can be directly generalized to an arbitrary manifold by simply replacing the partial derivatives by invariant differentiations with respect to a Cartan connection.

Nanoindentation is commonly used to probe local plastic properties of materials [1-4]. From these nanoindentation tests, finite element (FE) modeling is currently used to identify material data. The general ambition of this research is to extract the material parameters representative of the response of a new generation of Ti alloy, called Ti-555, in order to perform simulations on representative microscopic cells and guide the optimization of the alloy. In this paper, the identification of the flow parameters of the -phase of this alloy, using a microscopic crystal plasticity-based constitutive law is described. The nanoindentation tests are performed using a pyramidal Berkovich diamond indenter and the different slip systems of the b.c.c. -phase are supposed to be activated with identical critical shear stresses. The FE nanoindentation force-displacement curves obtained with the microscopic constitutive law are compared to the experimental ones. The influence of the orientation of the grains is also analysed. A previous sensivity analysis on different parameters with different constitutive laws and materials has shown a great influence of different parameters on the nanoindentation results but almost no influence of other parameters [5-6].

Herpes zoster (HZ) results from reactivation of the varicella-zoster virus (VZV), which remains latent in the dorsal root ganglia after varicella. HZ predominantly affects people over 50 years of age without gender distinction, and its incidence increases with age. The most feared complication of HZ is the zoster-associated pains (ZAP), which encompasses the prodromal, concomitant and post-zoster persistent pains. The latter neuralgias are particularly invalidating and notoriously difficult, or even impossible to abate with current therapies. Until now, the best ZAP prevention was achieved by antiviral treatment given during the earliest phase of the eruption. This treatment certainly reduces the duration and intensity of ZAP, but exerts little influence on post-zoster persistent pains. A vaccination boosting the specific anti-VZV immunity in order to decrease the HZ incidence and post-zoster pains appears promising. A recent study performed on 38.546 immunocompetent patients aged over 60 years assessed the efficacy of a single injection of an anti-zoster vaccine (Zostavax). The incidence of HZ and post-zoster pain was decreased by 50% and 66%, respectively. Vaccination could be considered as a valuable option to alleviate the feared complications of HZ. [less ▲]
