BACKGROUND Neuropathic pain (NeP) is a burdensome problem in all stages of cancer. Although clinical judgment is accepted as a surrogate for an objective gold standard in diagnosing NeP, no publications were found about its reliability. OBJECTIVES Therefore, levels of agreement on the clinical examination of NeP were estimated by calculating kappa-value (K) and percentage of pair wise agreeme...

We demonstrated that inhibition of neutral endopeptidase (NEP), a protease that degrades vaso- and neuroactive peptides, improves vascular and neural function in diabetic animal models. In this study we explored the role of NEP in neuropathy related to either insulin-deficient diabetes or diet-induced obesity using NEP deficient (-/-) mice. Initial studies showed that streptozotocin, in the abs...

Amyloid beta-peptide (Abeta) accumulation leads to neurodegeneration and Alzheimer disease; however, amyloid metabolism is a dynamic process and enzymic mechanisms exist for Abeta removal. Considerable controversy surrounds whether the intracellular domain of the amyloid precursor protein (AICD) regulates expression of the Abeta-degrading metalloprotease, neprilysin (NEP). By comparing two neur...

Amyloid β-peptide (Aβ) accumulation leads to neurodegeneration and Alzheimer's disease (AD). Aβ metabolism is a dynamic process in the Aβ production and clearance that requires neprilysin (NEP) and other enzymes to degrade Aβ. It has been reported that NEP expression is significantly decreased in the brain of AD patients. Previously we have documented hypoxia is a risk factor for Aβ generation ...

We investigated the distribution of neutral endopeptidase (NEP; EC 3.4.24.11) activity, a possible regulatory enzyme for neuropeptide-induced leukocyte activations, in each cell type of human blood leukocytes. The NEP activity assessed by an NEP inhibitor phosphoramidon-sensitive Met5-enkephalin degrading activity was present in neutrophils and the common acute lymphoblastic leukemia antigen (C...

Idiopathic diffuse hyperplasia of pulmonary neuroendocrine cells (IDHPNC) is a clinicopathological entity characterized by a diffuse hyperplasia of neuroendocrine cells involving distal bronchi and bronchioles. The pathogenesis of this syndrome remains unknown. The hyperplastic neuroendocrine (NE) cells contain multiple neuropeptides, including the bombesinlike peptides (BLP), which are likely ...

Neutral endopeptidase (NEP, E.C. 3.4.24.11), a widely distributed ectoenzyme, cleaves and inactivates a variety of biologically active peptides, including the tachykinin, substance P (SP). This study was undertaken to determine whether the modulation of SP airway smooth muscle contraction by NEP is age-dependent. We studied the contractile response of isolated tracheal rings from newborn and 12...

In this article we consider universal networks of evolutionary processors (NEP) having a small number of rules. We show that it is possible to construct a universal NEP with 5 rules when no input/output encoding is used, and a universal NEP with 4 rules in the case in which such an encoding is allowed. We also give a construction of a universal NEP with 7 rules that efficiently (in polynomial t...

Since its beginning in 1987, researchers and policymakers have touted the US Environmental Protection Agency National Estuary program (NEP) as one of the leading examples of collaborative institutions designed to resolve conflict and build cooperation at the watershed level. Using the NEP as an example, I summarize the advantages and disadvantages of collaborative institutions. Using data gathe...

BACKGROUND Similarities and differences on the nine-item and seven-item versions of painDETECT, a patient-reported screener to identify neuropathic pain (NeP), have not been psychometrically explored across NeP conditions. METHODS Scores on the nine-item painDETECT (seven pain symptom items, one pain course pattern item, one pain radiation item) range from -1 to 38; scores ≥19 indicate NeP is...
