Miglustat in patients with Niemann-Pick disease Type C (NP-C): A multicenter observational retrospective cohort study
2009
Miglustat has been shown to stabilize disease progression in children, juveniles and adults with Niemann-Pick disease type C (NP-C), a rare genetic disorder characterized by progressive neurological deterioration. We report findings from a retrospective observational cohort study assessing the effects of miglustat on neurological disease progression in patients treated in the clinical practice setting. Data from all NP-C patients prescribed miglustat at 25 expert centers were evaluated using a disease disability scale. The scale analyzed four key parameters of neurological disease progression in NP-C (ambulation, manipulation, language, swallowing). Mean individual parameter scores and a co…
Niemann-Pick disease type C symptomatology: an expert-based clinical description
2013
Niemann-Pick disease type C (NP-C) is a rare, progressive, irreversible disease leading to disabling neurological manifestations and premature death. The estimated disease incidence is 1:120,000 live births, but this likely represents an underestimate, as the disease may be under-diagnosed due to its highly heterogeneous presentation. NP-C is characterised by visceral, neurological and psychiatric manifestations that are not specific to the disease and that can be found in other conditions. The aim of this review is to provide non-specialists with an expert-based, detailed description of NP-C signs and symptoms, including how they present in patients and how they can be assessed. Early dise…
History and services of culture collections.
2003
Microbial culture collections aim at collecting, maintaining and distributing microbial strains among microbiologists, and are considered to be a means to preserve microbial diversity ex situ. This article reviews the early history of culture collections, which were first set up in the late nineteenth century, with the introduction of pure culture techniques. It also describes the international connections between culture collections, which led to the foundation of the World Federation for Culture Collections (WFCC) and the International Congress of Culture Collections (ICCC). An overview of the Spanish Type Culture Collection (CECT) is included, as well as a description of the services tha…
Two copper complexes from two novel naphthalene-sulfonyl-triazole ligands: different nuclearity and different DNA binding and cleavage capabilities.
2013
[EN] Two novel naphthalene-sulfonyl-triazole ligands, 5-amino-N1-(naphthalen-3-ylsulfony1)-1,2,4-triazole (anstrz) and 3,5-diamino-N1-(naphthalen-3-ylsulfony1)-1,2,4-triazole (danstrz), purposely designed to interact with DNA, have been prepared for the first time and then fully characterized by H-1, C-13 NMR and IR spectroscopy, mass spectrometry and elemental analysis. The crystal structures of two copper complexes of these derivatives, i.e. [Cu(anstrz)(4)(NO3)(2)]center dot 4CH(3)OH (1), mononuclear, and [Cu(danstrz)(mu-OAc)(2)](2)center dot 2(danstrz) (OAc = acetato) (2), dinuclear, have been determined by single-crystal X-ray diffraction. In both cases the ligand coordinates in a monod…
LIPIDOMICS OF HUMAN SKIN FIBROBLASTS IN NEIMANN-PICK DISEASE TYPE C
2013
Neimann-Pick Disease type C is a hereditary lysosomal storage disease due to mutations of the NPC1 or NPC2 genes. The products of these genes encodes for components of a lysosomal machinery that transport different kinds of lipids across the lysosomal membrane. The main abnormalities of NPC1 de ciency phenotype is the accumulation of free cholesterol (FC) and sphingolipids (GL) in brain, liver and other organs cells. Neurodegeneration and hepato-splenomegaly are common ndings. The NPC disease, in his severe onset, leads to a precocious exitus, though the inhibition of glyco-SL synthesis by miglustat has shown some clinical bene t. Recently the physiopathological mechanism has been partly el…
Longitudinal data from the international registry for Niemann-Pick disease type C (NPC)
2014
(0.69) years. Among 74/80 patients with available data, 10 (14%) patients had early-infantile (aged b2 years), 24 (32%) late-infantile (2 to b6 years), 24 (32%) juvenile (6 to b15 years), and 16 (22%) adolescent/ adult (≥15 years) onset of neurological manifestations. Mean (95%CI) composite disability scores at enrolment and last follow-up visit were 0.39 (0.34, 0.45; N = 75) and 0.45 (0.39, 0.51; N = 76), respectively. A total of 52/72 (72%) patients were categorised as ’improved/stable’ ;2 0/ 72 (28%) were categorised as ‘progressed’. Safety and tolerability findings for miglustat were in line with previous published data. A low proportion of patients had chronic diarrhoea during follow u…
1035 The International Registry for Niemann-Pick Disease Type C (NP-C) in Clinical Practice
2012
Background and Aim An international disease registry was started in September 2009 to evaluate the long-term disease course of NP-C in clinical settings. Methods Descriptive data from enrolment are presented for all patients with available data who were included in the Registry as of 19 th August 2011. Results 121 patients have been enrolled. The median (range) age at enrolment was 16.9 (0.9−56.6) years, age at onset of neurological manifestations was 8.2 ( Conclusions Over two-thirds of this NP-C cohort had infantile or juvenile onset of neurological manifestations; neonatal jaundice was observed more frequently in these patients versus adolescent/adult-onset patients.

A fixed point theorem for a Meir-Keeler type contraction through rational expression
2013
In this paper, we establish a new fixed point theorem for a Meir-Keeler type contraction through rational expression. The presented theorem is an extension of the result of Dass and Gupta (1975). Some applications to contractions of integral type are given.
Landesman-Lazer type (p, q)-equations with Neumann condition
2020
We consider a Neumann problem driven by the (p, q)-Laplacian under the Landesman-Lazer type condition. Using the classical saddle point theorem and other classical results of the calculus of variations, we show that the problem has at least one nontrivial weak solution.
