This paper proposes the application of the two well known models of negative binomial regression, namely the NB-1 and the NB-2, and the functional form of negative binomial regression, namely the NB-P, for the analysis of vehicle theft crime. The advantage of using the NB-P is that it parametrically nests both the NB-1 and the NB-2, and allows statistical tests of the NB-1 and the NB-2 models a...

Neuroblastoma (NB) is the most common and aggressive pediatric cancer, characterized by a remarkable phenotypic diversity and high malignancy. The heterogeneous clinical behavior, ranging from spontaneous remission to fatal metastatic disease, is attributable to NB biology and genetics. Despite major advances in therapies, NB is still associated with a high morbidity and mortality. Thus, novel ...

The nucleus basalis (NB) has been implicated in memory formation indirectly, by lesions, pharmacological manipulations, and neural correlates of learning. Prior findings imply that engagement of the NB during learning promotes memory storage. We directly tested this NB-memory hypothesis by determining whether stimulation of the NB induces behavioral associative memory. Rats were trained either ...

OBJECTIVE Although second-trimester nasal bone (NB) hypoplasia has been associated with fetal aneuploidy, its role as a single marker is still uncertain. Our objective was to evaluate the efficiency of NB hypoplasia as an independent marker for fetal aneuploidy. METHODS This was a prospective cohort study of women undergoing an anatomic survey between 16 and 22 weeks' gestation. The fetal NB ...

Neuroblastoma (NB) arises from primitive sympathetic neuroblasts in the adrenal gland or the sympathetic ganglion. NB in situ, sometimes observed in the adrenal glands of autopsied infants, is considered to be a premalignant lesion that may develop into NB. Little is understood about the morphological and biochemical changes that accompany this malignant progression. In this study, a unique mon...

BACKGROUND AND PURPOSE NB-3 is a member of the F3/contactin family of neural recognition molecules, which are crucial for cell morphogenesis and motility. NB-3 is expressed in neurons and plays an important role in axonal extension and neuronal survival. However, the role of NB-3 in cerebral ischemic injury remains unknown. METHODS Adult male wild-type and NB-3 knockout mice were subjected to...

Multifilamentary Nb-Ti superconducting wires with heterogenous flux pinning nano-structures have been fabricated using artificial pinning center (APC) technology. Pinning centers were introduced into Nb-Ti filaments, consisting of Cu-Ni, Nb and Nb+Ti rods with the triangular arrangement and the volume fraction of 17 %. After final hot extrusions, the APC wires were drawn down over a high strain...

conclusion the low prevalence of the nb absence in normal fetuses in the present study is compatible with the larger size of the nb in iranian people compared to other communities. meanwhile, the reference range of the nb length in normal iranian fetuses was established so that basic data could be recorded for further studies regarding the absence or presence of the nb in screening for chromoso...

In the title dinuclear Nb(V) compound, [Nb(2)(C(44)H(28)N(4))(2)O(3)], each Nb atom is seven-coordinated with three bridging O atoms and four N atoms from a chelating tetra-phenyl-porphyrinate anion. The Nb-O bond lengths range from 1.757 (6) to 2.331 (6) Å, and the average (niobium-pyrrole N atom) distance is 2.239 Å. In the dinuclear mol-ecule, the Nb⋯Nb separation is 2.8200 (8) Å, and the di...

Metastases in the bone marrow (BM) are grim prognostic factors in patients with neuroblastoma (NB). In spite of extensive analysis of primary tumor cells from high- and low-risk NB patients, a characterization of freshly isolated BM-infiltrating metastatic NB cells is still lacking. Our aim was to identify proteins specifically expressed by metastatic NB cells, that may be relevant for prognost...
