Filamin C accumulation is a strong but nonspecific immunohistochemical marker of core formation in muscle.

2002

Filamin C is the muscle isoform of a group of large actin-crosslinking proteins. On the one hand, filamin C is associated with the Z-disk of the myofibrillar apparatus and binds to myotilin; on the other hand, it interacts with the sarcoglycan complex at the sarcolemma. Filamin C may be involved in reorganizing the cytoskeleton in response to signalling events and in muscle it may, in addition, fulfill structural functions at the Z-disk. An examination of biopsies from patients with multi-minicore myopathy, central core myopathy and neurogenic target fibers with core-like target formations (TF) revealed strong reactivity of all the cores and target formations with two different anti-filamin…

Determination of Human Granulocyte Elastase by the Immunoactivation Method on the Hitachi® 717 Automated Analyser

1991

This paper describes a fully mechanized homogeneous immunoassay using the immunoactivation method for the rapid and specific determination of human granulocyte elastase (EC 3.4.21.37) in plasma. The method uses anti-elastase antibody fragments from sheep, conjugated to horseradish peroxidase. These enzyme-antibody conjugates bind to the elastase-alpha 1-proteinase inhibitor complex present in plasma. A separate sample blank with non-specific sheep antibody fragments conjugated to horseradish peroxidase corrects for errors introduced by the sample matrix. Measurements were performed with the clinical chemistry analyser Hitachi 717. A single determination can be performed in 10 min, requiring…

The nutritional requirements of infants. Towards EU alignment of reference values: the EURRECA network

2010

This paper presents a review of the current knowledge regarding the macro- and micronutrient requirements of infants and discusses issues related to these requirements during the first year of life. The paper also reviews the current reference values used in European countries and the methodological approaches used to derive them by a sample of seven European and international authoritative committees from which background scientific reports are available. Throughout the paper, the main issues contributing to disparities in micronutrient reference values for infants are highlighted. The identification of these issues in relation to the specific physiological aspects of infants is important …

Temperature dependence of the toxic effects of phenytoin on peripheral neuromuscular function of the rat tail.

1990

We studied the acute effects of a single dose of phenytoin (250 mg/kg) on peripheral neuromuscular function. The evoked muscle action potentials of the dorsal segmental muscles in the rat tail, and the conduction velocity of the dorsal nerve trunk which innervates them, were measured before and after the intraperitoneal injection of phenytoin. The experiments were performed at different temperatures, 27 (physiological tail temperature), 36 and 37 degrees C (physiological central temperature) in different groups of animals. The amplitudes of the evoked muscle action potentials in the treated groups showed no significant modifications at 27 degrees C, at 36 degrees C a small nonsignificant de…

Determination of Reference Values for NIST SRM 610-617 Glasses Following ISO Guidelines

2011

We present new reference values for the NIST SRM 610–617 glasses following ISO guidelines and the International Association of Geoanalysts’ protocol. Uncertainties at the 95% confidence level (CL) have been determined for bulk- and micro-analytical purposes. In contrast to former compilation procedures, this approach delivers data that consider present-day requirements of data quality. New analytical data and the nearly complete data set of the GeoReM database were used for this study. Data quality was checked by the application of the Horwitz function and by a careful investigation of analytical procedures. We have determined quantitatively possible element inhomogeneities using different …

C3 reference typing report and nomenclature revision.

1990

As the result of reference typing, two 'new' variants could be provisionally accepted (C3F045 and C3F015). The list of variants of the C3 polymorphism includes now 2 common and 29 rare variants.

Espirometría forzada en preescolares sanos bajo las recomendaciones de la ATS/ERS: estudio CANDELA

2009

Resumen: Introducción: actualmente no existen valores de referencia de espirometría forzada en preescolares sanos obtenidos según las recomendaciones publicadas por la American Thoracic Society (ATS) y la European Respiratory Society (ERS) en 2007. El objetivo del estudio es establecer valores espirométricos de referencia en niños preescolares sanos entre los 2 y los 7 años, según recomendaciones ATS/ERS. Material y método: estudio nacional, multicéntrico, descriptivo y transversal, en niños sanos de ambos sexos, mayores de 2 años y menores de 7. Las espirometrías forzadas se realizaron en laboratorios de función pulmonar de las 9 unidades de neumología pediátrica participantes. Los técnico…

Lovastatin attenuates ionizing radiation-induced normal tissue damage in vivo.

2009

Abstract Background and purpose HMG-CoA-reductase inhibitors (statins) are widely used lipid-lowering drugs. Moreover, they have pleiotropic effects on cellular stress responses, proliferation and apoptosis in vitro . Here, we investigated whether lovastatin attenuates acute and subchronic ionizing radiation-induced normal tissue toxicity in vivo . Materials and methods Four hours to 24h after total body irradiation (6Gy) of Balb/c mice, acute pro-inflammatory and pro-fibrotic responses were analyzed. To comprise subchronic radiation toxicity, mice were irradiated twice with 2.5Gy and analyses were performed 3weeks after the first radiation treatment. Molecular markers of inflammation and f…
