Reliability of physical functioning measures in ambulatory subjects with MS.
2005
Background and Purpose. One of the primary reasons for measuring outcomes during rehabilitation is to determine the effect of physiotherapy. Repeated measurement situations are susceptible to several sources of error, including inconsistencies caused by the subject, the procedure, the instrument and the examiner. Therefore, the reliability of the measures needs to be examined. Method. The present study used a repeated-measures design. Two studies were undertaken to examine the test–retest and inter-rater reliability for physical functioning measures. The interval between the measurements was one week. The sample consisted of 19 ambulatory subjects with mutliple sclerosis (MS) in the test–re…
Preeclampsia: a defect in decidualization is associated with deficiency of Annexin A2.
2020
Background Decidualization defects in the endometrium have been demonstrated at the time of delivery in women with severe preeclampsia and to linger for years, which suggests a maternal contribution to the pathogenesis of this condition. Global transcriptional profiling reveals alterations in gene expression, which includes down-regulation of Annexin A2 in severe preeclampsia patients with decidualization resistance. Objective We investigated the functional role of Annexin A2 deficiency during endometrial decidualization and its potential contribution to shallow trophoblast invasion during implantation and subsequent placentation using in vitro and in vivo modeling. Study Design Annexin A2 …
Digital Image Analysis Applied to Tumor Cell Proliferation, Aggressiveness, and Migration-Related Protein Synthesis in Neuroblastoma 3D Models
2020
Patient-derived cancer 3D models are a promising tool that will revolutionize personalized cancer therapy but that require previous knowledge of optimal cell growth conditions and the most advantageous parameters to evaluate biomimetic relevance and monitor therapy efficacy. This study aims to establish general guidelines on 3D model characterization phenomena, focusing on neuroblastoma. We generated gelatin-based scaffolds with different stiffness and performed SK-N-BE(2) and SH-SY5Y aggressive neuroblastoma cell cultures, also performing co-cultures with mouse stromal Schwann cell line (SW10). Model characterization by digital image analysis at different time points revealed that cell pro…
From stage to brain: Montage as a new principle of scientific narrative
2013
German Dadaists, Italian and Russian Futurists and Constructivists created in their experiments multi-medial orthopedic bodies as products of collage and montage. Sergei Eisenstein, who was influenced by these experiments, organized his theatrical productions as a chain of independent fragments capable of entering any possible combination/recombination and labelled this method “montage of attractions”. He used the same montage principle not only for a new theatrical or cinematic narrative but also to conceptualize the expressive movement of the theatrical or cinematic body created on stage and on screen. Finally he conceptualized montage not only as a means of conveying movement, but also o…
Subjectivisation and feminism. An analysis of a political manifesto
2004
The theme of this article is the the Italian feminist movement of the 1980s. That movement was characterised by political transformation and a crtitique of identity. The article takes as its point of departure the inaugural speech of the movement, the manifesto "Piu donne che uomini" (1983). The analysis that we present is inspired in the work of Michel Foucault. It aims to show to that the production of new feministic subjectivities, when fighting the symbolic dimension of masculine domination, has an intrinsically political character. In the 1980s, in the Italian context and particularly in the feminist movement, the rules of the political game set up by the events of 1968 materialized. T…
Experience, Subjectivity and Politics in the Italian Feminist Movement
2006
This article describes the political practices of a part of the Italian women’s movement that, as of the 1980s, gave way to the sexual difference thought. Through a political analysis of their own experience, which removed any humanist identity assumptions, the women’s movement generated new practices and discourses. With these, women were able to exert self-criticism, and simultaneously to produce new subjectivities articulated around the sexual difference concept. The difference thought helped highlight the limits of institutional policy, renewing the premises of political analysis and redefining the borders of what was deemed to be ‘political’. Intended to foster dialogue with other femi…
Extraction of objects from structured backgrounds in the cat superior colliculus. Part II
1980
Specific changes occur in the cells of the uppers layers of the cat's superior colliculus when a two dimensional noise (background) is superimposed onto a deterministic signal (spot of light). Some of the measurements can be interpreted as meaning that some cells only react to certain relative movements of object (spot) and background (noise). The movement of the visual background is interpreted as environmental movement occurring due to the animal's own movement. The results of the measurements provide all the necessary presuppositions for a distinction between the animal's own velocity and that of the object (Part I). The experimental results can be interpreted with a model. The essential…
The alignment of head nods with syntactic units in Finnish Sign Language and Swedish Sign Language
2016
In this paper we examine the relationship between specific head movement events – head nods, often treated as prosodic boundary markers – and syntactic units in Finnish (FinSL) and Swedish Sign Language (SSL). In the study we investigated the alignment of head nods with syntactic units on the basis of a total of 20 (10+10) FinSL and SSL narratives. The results of the study show that in both languages head nods appeared similarly on syntactic boundaries and that the tendency was to align nods sentence-finally. However, not all head nods behaved this way: for example, a relatively large number of head nods were also found to occur sentence-initially or elsewhere in the sentence. Furthermore, …
On the rhythm of head movements in Finnish and Swedish Sign Language sentences
2016
This paper investigates, with the help of computer-vision technology, the similarities and differences in the rhythm of the movements of the head in sentences in Finnish (FinSL) and Swedish Sign Language (SSL). The results show that the movement of the head in the two languages is often very similar: in both languages, the instances when the movement of the head changes direction were distributed similarly with regard to clause-boundaries, and the contours of the roll (tilting-like) motion of the head during the sentences were similar. Concerning differences, direction changes were found to be used more effectively in the marking of clause-boundaries in FinSL, and in SSL the head moved near…
Sorbitol-penetration enhancer containing vesicles loaded with baicalin for the protection and regeneration of skin injured by oxidative stress and UV…
2018
Abstract Aiming at improving the protective effects of baicalin on the skin, new highly-biocompatible penetration enhancer containing vesicles (PEVs) were developed by modifying the base formulation of transfersomes with sorbitol, thus obtaining sorbitol-PEVs. An extensive evaluation of the physico-chemical features of both transfersomes and sorbitol-PEVs was carried out. Transfersomes were mainly close-packed, multi-compartment vesicles, while sorbitol-PEVs appeared mostly as single, spherical, unilamellar vesicles. All the vesicles were small in size (∼128 nm) and negatively charged (∼−67 mV), without significant differences between the formulations. The in vitro delivery of baicalin to i…
