INTRODUCTION: Horseshoe kidney occurs in 1 per 400-800 live births and are more frequently observed in males (M:F 2:1). Ureteropelvic junction obstruction (UPJO) is commonly associated with horseshoe kidneys. The variable blood supply, presence of the isthmus and high insertion of the ureter contribute to this problem. CASE REPORT: An asymptomatic 6 year-old boy presented with antenatal hydronephrosis. Ultrasonography and CT scan demonstrated left UPJO associated with a horseshoe kidney...

INTRODUCTION: Exposure to metallic mercury can cause severe accidental intoxications in children, whose clinical symptoms can vary depending on the route of administration, the dose, as well as the time and duration of the exposure. It has become unusual in France, yet it must be considered when taking a patient's medical history in cases of multisystemic involvement without a clear explanation. CLINICAL CASE: We report the case of a 12-year-old patient hospitalized because of a cough, poor general condition, chills, night sweats, psychomotor retardation, and skin lesions that had been developing for several weeks...

Molybdoenzymes are an ancient protein family found in phylogenetically and ecologically diverse prokaryotes. Under anaerobic conditions, respiratory molybdoenzymes catalyze redox reactions that transfer electrons to a variety of substrates that act as terminal electron acceptors for energy generation. Here, we used probe sequences to conduct an extensive genomic survey and phylogenetic inference for NarG, DmsA, TorA and nine other respiratory molybdoenzyme subfamilies. Our analysis demonstrates their abundance in 60% of prokaryotic phyla...

OBJECTIVES: Simple nephrectomy is performed for a benign pathology that does not require the excision of either the adrenal gland or any adenopathies. When it is carried out in cases of stone disease, however, it is frequently not a "simple" technique owing to the presence of significant inflammation and infection. METHODS: Ninety-six simple laparoscopic nephrectomies performed because of stone disease between 2006 and 2015 were retrospectively studied. A descriptive statistical analysis was performed, as well as an evaluation of the associated complications...

Nano-sized Prussian blue (PB) cubes were synthesized at room temperature by simply stirring the mixture of surface modified iron oxide nanoparticles (IONPs) and potassium ferrocyanide in an aqueous acid solution. The nanocubes were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM) and X-ray diffraction (XRD). The influence of different molecules modified on the surface of IONPs on the cube formation was discussed. The surface modification with dimercaptosuccinic acid (DMSA), 3-aminopropyltriethoxysilane (APTS) and citric acid (CA) all displayed a key role in the formation precess of PB nanocubes, but which could not be formed as bare IONPs or Fe3+ were used as precursor...

BACKGROUND: Nanoparticles' unique features have been highly explored in cellular therapies. However, nanoparticles can be cytotoxic. The cytotoxicity can be overcome by coating the nanoparticles with an appropriated surface modification. Nanoparticle coating influences biocompatibility between nanoparticles and cells and may affect some cell properties. Here, we evaluated the biocompatibility of gold and maghemite nanoparticles functionalized with 2,3-dimercaptosuccinic acid (DMSA), Au-DMSA and γ-Fe2O3-DMSA respectively, with human mesenchymal stem cells...
