Objective: A recent update of the French cohort of uranium miners added seven years of follow-up data. We use these new data to look for new possible radon-related increased risks and refine the estimation of the potential association between cumulative radon exposure and four cancer sites: lung cancer, kidney cancer, brain and central nervous system (CNS) cancer and leukemia (excluding chronic lymphocytic leukemia, which is not radiation-induced).
Methods: Several parametric survival models are proposed, fitted and compared under the Bayesian paradigm, to perform new and original exposure-risk analyses.
Introduction: The enhanced recovery program (ERP) is a management mode whose objective is to reduce the risk of complications and allow the patient to recover more quickly all its functional capacities and to reintegrate at most quickly and safely in his usual environment. This intentionally synthetic document aims to disseminate in the urological community the main points of the ERP recommendations for cystectomy. This work, coordinated by AFU, involves several other partners.

Infusion of CER-001 3 mg/kg exhibited a potentially favorable effect on plaque burden in the CHI-SQUARE (Can HDL Infusions Significantly Quicken Atherosclerosis Regression) study. Since baseline atheroma burden has been shown as a determinant for the efficacy of HDL infusions, the degree of baseline atheroma burden might influence the effect of CER-001.

We investigated the reasons why cancer patients consult a GP-Ho versus a GP-CM for supportive care and the GPs' motivations for their prescriptions.
Methods: This observational survey was carried out in France between October 2008 and October 2011.
The diagnosis of pyeloureteritis cystica is rare. Data from the literature about this disease are limited. Pyeloureteritis cystica is described as a benign inflammatory disease of the urinary tract, resulting from chronic inflammation of the urothelium.

The indirect toxicity of the inhibitors of tyrosinekinases is much less known and several hypotheses appear. Usually, the common side effects of the inhibitors of tyrosine-kinases can be easily managed and are reversible when the treatment is stopped.

Recently introduced digital signal processing (DSP) can be used, instead of two lock-in amplifiers, for the optical signal demodulation at two modulation frequencies. In order to establish the merits of double-modulation FT-IR spectrometry with DSP, spectro-electrochemical experiments are performed in the attenuated total reflection configuration and with the commonly used ferri/ferrocyanide redox couple.

In particular, IRSE can be useful for detecting adsorption-induced changes in the IR spectra of self-assembled monolayers (SAMs), and unlike traditional IR absorption spectroscopies, IRSE provides useful information about the phase of the reflected radiation from the SAMs. However, in the standard IRSE experimental geometry using flat substrates for SAMs, the detectable signal containing these phase data is considerably weaker than the corresponding absorbance data.

The duration of this follow-up and the frequency of examinations depend on the patient's level of risk. Early detection of metastases has a limited therapeutic value at the present time, apart from tumours with a good prognosis or for the management of complications.

Fifty and one-hundred micrometer diameter nanostructured gold hollow microspheres (GHSs), in >98% purity, have been prepared by using ceramic hollow spheres, CHSs, as templates. Tennanometer diameter gold nanoparticles were covalently linked to the thiol moiety of (3-mercaptopropyl)trimethoxysilane, which had been self-assembled onto the CHSs. Greater structural strength was obtained by the generation of additional gold nanoparticles, in situ on the gold nanoparticle coated CHSs (by immersing the gold nanoparticle coated CHSs into an aqueous mixture of hydroxylamine and gold chloride).

Octyl octanoate (O-OL) underwent hydrolysis in sodium octanoate (NaOA) reversed micelles in 85:15 = isooctane:octanol (OL) (v/v), containing w = [H2O]/[NaOA] = 40. The products of the hydrolysis, octanoic acid (OA) and octanol (OL), lead to the formation of additional (albeit smaller) reversed micelles; hence the process is considered to be self-reproducing. Self-reproduction was found to be catalyzed by lithium hydroxide, solubilized in the water pools, as well as by hydrogen sulfide, added to the solution of the reversed micelles.

Gold nanoparticles attached to the P2VP polymer brushes dramatically enhanced the pH-induced shift in the T-SPR absorption spectra. (A 50 nm shift of the absorption maximum of the T-SPR spectrum of the supporting gold nanoislands was observed upon changing the pH from 5.

Urinary tract infection is frequent during pregnancy with a high potential risk for mother and child. Based on a review of the literature and a retrospective survey conducted in 20 representative French university hospitals during 1993, the authors propose a practical review designed to standardize the therapeutic approach to this disease. They define a high-risk group which requires systematic screening and close surveillance during pregnancy.
