Tratamiento de la disfonía por déficit de cierre glótico mediante laringoplastia de medialización con injertos de grasa autólogos. Revisión del proce…

2020

Introducción Una de las principales técnicas quirúrgicas para el tratamiento de la disfonía por insuficiencia glótica ha sido tradicionalmente la laringoplastia de medialización mediante diversos procedimientos, entre ellos la infiltración de diversas sustancias. La generalización del uso de injertos grasos en el ámbito de la cirugía reconstructiva se ha traducido en los últimos años en el uso de este material autólogo como relleno para realizar estas infiltraciones. No obstante, hasta 2016, sólo existían 4 estudios en los que se empleara grasa obtenida mediante lipoaspiración, y ninguno de ellos utilizó injertos procesados mediante centrifugación. Por otra parte, aunque el campo de los inj…

Visual grouping under isoluminant condition: impact of mental fatigue

2016

Instead of selecting arbitrary elements our visual perception prefers only certain grouping of information. There is ample evidence that the visual attention and perception is substantially impaired in the presence of mental fatigue. The question is how visual grouping, which can be considered a bottom-up controlled neuronal gain mechanism, is influenced. The main purpose of our study is to determine the influence of mental fatigue on visual grouping of definite information – color and configuration of stimuli in the psychophysical experiment. Individuals provided subjective data by filling in the questionnaire about their health and general feeling. The objective evidence was obtained in t…

Dependence of seed nitrogen concentration on plant nitrogen availability during the seed filling in pea

1999

Abstract The final seed nitrogen (N) concentration of the pea ( Pisum sativum L.) varies greatly with environment. These variations seem to be related to N availability in the plant. To understand such an effect, the pattern of seed N concentration during seed filling was analysed at a given node as the ratio of seed N accumulation rate and seed dry matter accumulation rate. Three experiments were conducted in the field and glasshouse. Pea genotypes ‘Solara’, ‘Frisson’ and its non-nodulating mutant ‘P2’ were grown and different treatments were applied to manipulate N availability during seed filling. Treatments included N supply (addition of N fertiliser), depodding (removal of pods) and de…

Observations préliminaires à l'étude des remplissages des tombes du Néolithique moyen I de Gurgy "Les Noisats" (Yonne)

2008

This paper presents results of experimental digging and filling of a pit in gravel context. That experimentation is the first step of an integrated analysis about sedimentary dynamic in neolithic burials from Gurgy « Les Noisats » (Yonne, France).

Adipose stem cells on the basis of tumor transformation

Mesenchymal stem cells thanks to their differentiated multipotent ability are considered the most promising candidate for tissue engineering and regenerative medicine. The source of mesenchymal stem cells up to about 20 years was represented by the bone marrow, but due to their limited amount of cells together with a very invasive and painfull surgical treatment, poorly accepted by patients, has led the scientific community to investigate an alternative mesenchymal stem cells source with similar properties. In particular, the adipose tissue has attracted the greatest interest thanks to its relative abundance, the easy of availability and the large amounts of mesenchymal stem cells which are…

The ends of manifolds with bounded geometry and linear growth

2004

We prove that simply connected open manifolds of bounded geometry, linear growth and sublinear filling growth (e.g. finite filling area) are simply connected at infinity.

No-flow temperature and solidification in injection molding simulation

2011

The no‐flow temperature (NFT) is a parameter representing the rheological solidification temperature of a polymer. A polymer, during injection molding filling stage, can stop its flow because of its high viscosity, although it is not yet fully solidified by means of glass transition or crystallization. The NFT is used in most of injection molding simulation packages: with this simple parameter it is possible to reduce the errors deriving from viscosity extrapolation at relatively low temperatures. The viscosity measurements for polymers are usually carried out at high temperatures, and the viscosity models can fail in prediction at temperatures close to the glass transition or crystallizati…

Apical seal comparison of low-temperature thermoplasticized gutta-percha technique and lateral condensation with two different master cones

2007

Aim: To compare the apical sealing in mesio-buccal canals of extracted molars obturated with low-temperature thermoplasticized gutta-percha or cold lateral condensation techniques using a .06 or a .02 mm/mm tapered gutta-percha master cone. The secondary aim was to evaluate the depth of spreader penetration in root canals using a .06 or a .02 mm/mm tapered gutta-percha master cone. Methodology: Forty-four mesio-buccal curved canals (25-40º) were instrumented with .06 nickel-titanium rotary instruments and randomly distributed into two control groups (n=4) and three experimental groups (n=12) for obturation by the Ultrafil® 3D system or by cold lateral condensation with .06 or .02 tapered ma…
