New Fe-based bulk glassy alloys were synthesized in the (Fe0.75B0.15Si0.10)100−x Nbx system by copper mould casting. The maximum diameter of the bulk glassy alloy rod was 0.5 mm at 1 at%Nb, 1.0 mm at 2 at%Nb and 1.5 mm at 4 at%Nb. No glass transition is observed at 0 at%Nb, but the addition of Nb causes the appearance of glass transition before crystallization. The glass transition temperature ...

nail biting (nb) is a common, but unresolved, problem in psychiatry, psychology, medicine and dentistry. while it seems that nb is a simple behavior that can be stopped easily, many of the children with nb have already tried to stop it, but they have not been successful. the frustrations due to failed attempt involve others such as parents and siblings. the present review aims at providing an o...

In plants, many of the innate immune receptors or disease resistance (R) proteins contain a NB-LRR (Nucleotide-binding site, Leucine-rich repeat) structure. The recent findings regarding NB-LRR signaling are summarized in this article. An emerging theme is that two NB-LRRs can function together to mediate disease resistance against pathogen isolates. Also, recent results delineate the NB-LRR pr...

In the title compound, [Nb(CH(3)O)(3)(C(5)H(7)O(2))Cl], the Nb(V) atom is coordinated by two O atoms from the chelating acetyl-acetonate ligand, three O atoms from the methano-late groups and one chloride ligand. The octa-hedral environment around niobium is slightly distorted with Nb-O distances in the range 1.8603 (15)-2.1083 (15) Å and an Nb-Cl distance of 2.4693 (9) Å. The O-Nb-O angles var...

Neuromedin B (NB) is a recently discovered neuropeptide related to bombesin. It is localized to thyrotropes and we have previously shown that it directly inhibits thyrotropin (TSH) release from the anterior pituitary gland of euthyroid rats. In the current studies, we further evaluated the action of NB and antiserum directed against it in euthyroid rats and compared the actions with those in hy...

We report the annealing effects on the magnetic properties of Cu-17vol.% Nb micro-composites. Samples prepared by bundling and drawing process with different deformation degree and subsequent vacuum heat treatment. The Cu-Nb interface structural change due to mostly the recrystallization and coarsening of the Nb filaments. The magnetic properties caused by the proximity effect and the Cu-Nb int...

The novel p73 gene is a structural and, in overexpression systems, functional p53 homologue. p73 resides on chromosome 1p36.33 within a commonly deleted region in neuroblastoma (NB) and other human tumors. To evaluate p73's candidacy for a NB suppressor, we analyzed 28 primary NB tumors, 14 NB cell lines, and 5 non-NB malignant pediatric tumors. We determined the level of p73 expression and its...

Neuroblastoma (NB) is a heterogeneous, and particularly malignant childhood neoplasm in its higher stages, with a propensity to form metastasis in selected organs, in particular liver and bone marrow, and for which there is still no efficient treatment available beyond surgery. Recent evidence indicates that the CXCR4/CXCL12 chemokine/receptor axis may be involved in promoting NB invasion and m...

PURPOSE Notch signaling has been implicated to play a critical role in the tumorigenesis of neuroblastoma (NB) and can modulate calreticulin (CRT) expression that strongly correlates with tumor differentiation and favorable prognosis of NB. We thus sought to determine how Notch regulates CRT expression and affects NB tumor behavior. EXPERIMENTAL DESIGN The Notch-dependent regulation of CRT ex...

In order to develop a relevant xenogenic animal model of neuroblastoma (NB), we compared the tumorigenicity and metastatic potential of SK-N-SH and SK-N-DZ NB cell lines in nude mice and NOD/SCID Il2rg null (NSG) mice. Subcutaneous injection of cell lines induced tumor formation only in NSG mice and was accompanied by metastasis to the liver, adrenal glands, skull and bone marrow. NSG mice inje...
