Bilateral nephroblastomatosis (NB) is an uncommon renal anomaly characterized by multiple confluent nephrogenic rests scattered through both kidneys, with only a limited number of cases reported in the medical literature. Some of these children may have associated either Perlman or Beckwith-Wiedemann syndrome and others do not demonstrate syndromic features. We report a full-term boy with antev...

Narrowband ultraviolet B (NB-UVB) induces different immunological features from broadband ultraviolet B and is effective for the treatment of various cutaneous diseases. UV exposure alters the morphology and function of epidermal Langerhans cells (LCs), which can elicit cutaneous immunosuppressive responses. Recent studies have proposed that LCs serve as immunoregulatory cells in UV-induced imm...

Primary intrarenal/perirenal neuroblastoma (NB) is NB that primarily arises in intrarenal and/or perirenal regions. Regarding its location, this tumor can mimic Wilms' tumor a more common pediatric renal tumor at presentation. Owing to diference in clinical management andprognosis, it is crucial to distinguish primary intrarenal/perirenal NB from Wilms' tumor at the time of diagnosis. Recogniti...

NiTi wires were brazed together via eutectic reaction between NiTi and Nb powder deposited at the wire contact region. Phase transformation and deformation behavior of the NiTi-Nb eutectic microstructure were investigated using transmission electron microscopy (TEM) and cyclic loading-unloading tests. Results show that R phase and B19' martensite transformation are induced by plastic deformatio...

A monolayer of Nile Blue (NB) has been covalently immobilized on the self-assembled thiol-monolayer modified gold electrode. Cyclic voltammograms indicated a stable and reverse redox process of NB bonded on the electrode surface. The mechanisms of redox process coupling with proton transfer were proposed. The NB-modified electrode showed excellent electrocatalytic activity toward Nicotinamide a...

An iterative method for the minimization of convex functions f : R → R, called a Newton Bracketing (NB) method, is presented. The NB method proceeds by using Newton iterations to improve upper and lower bounds on the minimum value. The NB method is valid for n = 1, and in some cases for n > 1 (sufficient conditions given here). The NB method is applied to large scale Fermat–Weber location probl...

BACKGROUND Neuroblastoma (NB) is one of the most malignant neoplasms in childhood. In Japan, while a nationwide screening program at six months of age was introduced in 1985, its efficacy has not been systematically evaluated before or after its introduction. The screening test was changed from a qualitative method to a quantitative method (i.e., high performance liquid chromatography, HPLC) wi...

The Toll-like receptor 9 (TLR9) evolved to cope with pathogens, but it is expressed in a variety of tumors for reasons that are unclear. In this study, we report that neuroblastoma (NB) cells express functional TLR9. Liposome-complexed CpG oligonucleotides inhibited the proliferation of TLR9-expressing NB cells and induced caspase-dependent apoptotic cell death. Inhibitory oligonucleotides (iOD...

This study explores a facile method to prepare an efficient and durable support for Pt catalyst of polymer electrolyte membrane fuel cell (PEMFC). As a candidate, Nb-doped TiO2 (Nb-TiO2) nanofibers are simply fabricated using an electrospinning technique, followed by a heat treatment. Doping Nb into the TiO2 nanofibers leads to a drastic increase in electrical conductivity with doping level of ...

The resistance of neuroblastoma (NB) cells to tumor necrosis factorrelated apoptosis-inducing ligand (TRAIL)-induced apoptosis has been attributed to a lack of caspase 8 expression. Here we demonstrate a clinically applicable molecular targeting strategy that not only increases caspase 8 expression ex vivo in NB cell lines but also in the tumor tissues of NB patients receiving IFNtreatment. We ...
