Global gene expression profiles in skeletal muscle of monozygotic female twins discordant for hormone replacement therapy

2010

Aging is accompanied by inexorable loss of muscle tissue. One of the underlying causes for this is the massive change in the hormonal milieu of the body. The role of a female sex steroid – estrogen – in these processes is frequently neglected, although the rapid decline in its production coincides with a steep deterioration in muscle performance. We recruited 54- to 62-year-old monozygotic female twin pairs discordant for postmenopausal hormone replacement therapy (HRT, n = 11 pairs; HRT use 7.3 ± 3.7 years) from the Finnish Twin Cohort to investigate the association of long-term, estrogen-based HRT with skeletal muscle transcriptome. Pathway analysis of muscle transcript profiles revealed …

On the Modeling of Transcatheter Therapies for the Aortic and Mitral Valves: A Review

2022

Transcatheter aortic valve replacement (TAVR) has become a milestone for the management of aortic stenosis in a growing number of patients who are unfavorable candidates for surgery. With the new generation of transcatheter heart valves (THV), the feasibility of transcatheter mitral valve replacement (TMVR) for degenerated mitral bioprostheses and failed annuloplasty rings has been demonstrated. In this setting, computational simulations are modernizing the preoperative planning of transcatheter heart valve interventions by predicting the outcome of the bioprosthesis interaction with the human host in a patient-specific fashion. However, computational modeling needs to carry out increasingl…

Developing placement assessment in integration training for adult migrants in Finland

2017

As part of integration training in Finland, migrants are provided with Finnish or Swedish language courses. The linguistic objective is to provide migrants with the basic language skills required in daily life. To find the most suitable teaching group for learners in integration training, a placement assessment is carried out. This includes assessment of learners’ current proficiency level in the target language and study skills/experience. In this article we describe a project to develop a national test system for placement assessment (see Ohranen et al. 2015). En Finlande, des migrants adultes suivent des cours de finnois ou de suédois dans le cadre d’une formation pour l’intégration. L’o…

Simulation of Fatigue Delamination Growth in Composites with Different Mode Mixtures

2007

A numerical model, obtained by implementing a cyclic damage model in the framework of an interface element, is here proposed to reproduce the crack growth in laminated composites subjected to cyclically repeated loads. This model, which differs from the few studies in the literature on the topic, applies not only to single fracture modes but also to mixed modes, and to constant or variable crack growth rates. The applied load (in terms of force or displacement) is assumed to oscillate between a minimum and a maximum constant value. The Paris curve can be reproduced with accuracy once some parameters in the numerical model are tuned with experiments. These parameters are preliminarily found…

Effective reference and current integration for large displacement interface

2016

The most common interface formulations proposed in literature are generally based on the restrictive hypothesis of small strains and small displacements and, even though their application to geometrically nonlinear problems is of paramount interest, only few contributions are available in literature. Motivations are probably due to the difficulties encountered on such formulation, as already mentioned by several authors. A pioneering formulation is the finite displacement three-dimensional interface developed by Ortiz and Pandolfi in [1], where normal and tangential traction components are evaluated with respect to the middle surface in the current configuration, producing a non-symmetric g…

"Rational herding in crowdfunding, social preferences under uncertainty, and overplacement in known and unknown tasks: a behavioral approach"

2020

It has been proved in this dissertation how experimental economics continues to be a tool that, as it nourishes theoretical economics (and viceversa), it keeps producing results that are necessary to understand how to articulate social relations which, ultimately, have consequences oneconomic relations. Specifically, Chapter 1 has studied how the dissemination of new information affects crowdfunding markets and the generation of herding behaviour. Specifically, we provide evidence in that such behaviour is rational and could be well moulded through optimal choice under uncertainty with Bayesian review of beliefs. In this sense, the effect of the first sponsors on the agents# behaviour has b…

Digital Correlation Method Based on Micro-geometrical Texture Pattern for Strain Field Measurement

2011

International audience; Image correlation methods are widely used in experimental mechanics to obtain displacement field measurements. Currently, these methods are applied using digital images of the initial and deformed surfaces sprayed with black or white paint. Speckle patterns are then captured and the correlation is performed with a high degree of accuracy to an order of 0.01 pixels. In 3D, however, stereo-correlation leads to a lower degree of accuracy. Correlation techniques are based on the search for a sub-image (or pattern) displacement field. The work presented in this paper introduces a new correlation-based approach for 3D displacement field measurement that uses an additional …

BIFOCAL PAIRS OF IMAGES FOR LOW-COST SURVEY IN CLOSE RANGE PHOTOGRAMMETRY

2019

Abstract. This paper present a method for close range photogrammetry based on an camera positioning scheme in which two cameras capture an equal portion of an object at the same scale, but have different focal lengths and camera-to-object distances. This scheme is alternative to the stereoscopic scheme and is associated with a system of equations which permits one to calculate first the relief displacement of points on a photograph and then their relief relative to a reference plane. The obtained relief and relief displacement values can be used to produce low-cost orthophotographs by using software for image processing, which doesn’t need to be dedicated, but has to provide measurement and…

At the Roots of Product Placement: The Mere Exposure Effect

2013

The present study aims to analyze the effect of product placement on attitude change and takes into consideration psychological models of the mere exposure effect. A sample of high school students watched an excerpt from two widely-distributed movies in which several products were shown by using the technique known as product placement. The results indicate that students who saw the commercial brand liked the products more than those who didn’t see it. This effect, in line with the literature on the product placement effect, seems to be independent from the recognition of the brand in the movie excerpt. This study also shows that, in the high involvement condition, one exposure is enough to…
