Common Data Elements for Muscle Biopsy Reporting

2015

Context There is no current standard among myopathologists for reporting muscle biopsy findings. The National Institute of Neurological Disorders and Stroke has recently launched a common data element (CDE) project to standardize neuromuscular data collected in clinical reports and to facilitate their use in research. Objective To develop a more-uniform, prospective reporting tool for muscle biopsies, incorporating the elements identified by the CDE project, in an effort to improve reporting and educational resources. Design The variation in current biopsy reporting practice was evaluated through a study of 51 muscle biopsy reports from self-reported diagnoses of genetically confirmed or u…

Un paisaje que cambia. Monumentos que fueron en tierras valencianas

2001

En el presente artículo se estudian varios edificios de la Comunidad Valenciana, que se remontan a una época relativamente lejana. A la luz de los estudios recientes y de la investigación arqueológica se puede constatar la escasez de restos, a excepción de algún caso aislado. El contenido comprende fundamentalmente murallas, castillos, palacios señoriales, torres, algún convento o ermita, y el Jardín Botánico del palacio del Arzobispo en Puzol. Las comarcas donde se ubican los monumentos son: "el Camp de Morvedre", "el Camp del Turia", "l'Horta Nord", "la Plana de Utiel-Requena", "la Ribera Alta", "la Safor", "la Vall d'Albaida" y "la Costera".

Aging, muscle fiber type, and contractile function in sprint-trained athletes

2006

Biopsy samples were taken from the vastus lateralis of 18- to 84-yr-old male sprinters ( n = 91). Fiber-type distribution, cross-sectional area, and myosin heavy chain (MHC) isoform content were identified using ATPase histochemistry and SDS-PAGE. Specific tension and maximum shortening velocity ( Vo) were determined in 144 single skinned fibers from younger (18–33 yr, n = 8) and older (53–77 yr, n = 9) runners. Force-time characteristics of the knee extensors were determined by using isometric contraction. The cross-sectional area of type I fibers was unchanged with age, whereas that of type II fibers was reduced ( P < 0.001). With age there was an increased MHC I ( P < 0.01) and re…

CD146+ bone marrow osteoprogenitors increase in the advanced stages of primary myelofibrosis

2008

Abstract CD146+ bone marrow stromal cells have been recently recognized as clonogenic osteoprogenitors able to organize a complete hematopoietic microenvironment. In this study we used immunohistochemical analysis to investigate the contribution of CD146+ bone marrow osteoprogenitors to the stromal remodeling occurring in the different stages of primary myelofibrosis. We found that CD146+ cells sited at the abluminal side of the bone marrow vessels and branching among hematopoietic cells significantly increased in the advanced stages of primary myelofibrosis (p<0.001), paralleling the extent of fibrosis (r=0.916, p<0.0001) and the microvascular density (r=0.883, p<0.0001). Coherently with a…

Corpus callosum area in patients with bipolar disorder with and without psychotic features: an international multicentre study

2015

Background Previous studies have reported MRI abnormalities of the corpus callosum (CC) in patients with bipolar disorder (BD), although only a few studies have directly compared callosal areas in psychotic versus nonpsychotic patients with this disorder. We sought to compare regional callosal areas in a large international multicentre sample of patients with BD and healthy controls. Methods We analyzed anatomic T-1 MRI data of patients with BD-I and healthy controls recruited from 4 sites (France, Germany, Ireland and the United States). We obtained the mid-sagittal areas of 7 CC subregions using an automatic CC delineation. Differences in regional callosal areas between patients and contr…

The lipoprotein receptor LRP1 modulates sphingosine-1-phosphate signaling and is essential for vascular development

2014

Low density lipoprotein receptor-related protein 1 (LRP1) is indispensable for embryonic development. Comparing different genetically engineered mouse models, we found that expression of Lrp1 is essential in the embryo proper. Loss of LRP1 leads to lethal vascular defects with lack of proper investment with mural cells of both large and small vessels. We further demonstrate that LRP1 modulates Gi-dependent sphingosine-1-phosphate (S1P) signaling and integrates S1P and PDGF-BB signaling pathways, which are both crucial for mural cell recruitment, via its intracellular domain. Loss of LRP1 leads to a lack of S1P-dependent inhibition of RAC1 and loss of constraint of PDGF-BB-induced cell migra…

Análisis de la pintura mural de una domus excavada en el municipio romano de Lesera (la Moleta dels Frares, Forcall – Castelló).

2010

En este trabajo se aborda la caracterización de los materiales empleados en pigmentos, preparaciones, morteros y molduras de la decoración mural de una domus excavada en la ciudad romana de Lesera (Forcall, Castellón). Los análisis elementales mediante EDXRF muestran la utilización de compuestos de hierro y compuestos de plomo en los pigmentos rojos; compuestos de hierro en los amarillos; negros de origen vegetal y blancos a base de compuestos de calcio. Los difractogramas XRD revelan el uso de calcita y cuarzo en las preparaciones del muro y de calcita en las molduras. Las estratigrafías de las muestras analizadas mediante SEM-EDS revelan una estructura de capas compuesta por un mortero ba…

Photoplethysmography system for blood pulsation detection in unloaded artery conditions

2012

Photoplethysmography (PPG) is an optical method of blood pulsation recording and has been extensively studied for decades. Recently PPG is widely used in the medical equipment for patient monitoring and in laboratories for research and physiological studies. In spite of the technological progress in the field of medical equipment, there are no generally accepted standards for clinical PPG measurements up to date. One of the most important factors affecting PPG waveform is the contact pressure between tissue and PPG probe. The aim of the current study was to develop and evaluate a system for software-assisted PPG signal acquisition from the unloaded artery. Novel PPG waveform derived Optimal…
