Abstract:

This study examined the relationship between adolescents' use of texting and their level of identity development, cognitive autonomy, and self-esteem. One hundred and nineteen Utah State University students participated in this study by filling out a questionnaire that included a section designed specifically to learn the texting habits of the participants, and also included sections derived from previously existing measures on identity, autonomy, and self-esteem. The results show statistical significance of age and texting. Participants who were 23 years+ sent significantly less than

Abstract:

Disorders of the autonomic nervous system constitute serious complications of spinal cord injury (SCI) and their treatment is usually highly prioritised by spinal patients. Among these, autonomic dysreflexia and impaired thermoregulation are potentially life threatening conditions and require effective management. Olfactory ensheathing cells (OECs), progenitor cells and polymeric scaffolds have been tested in animal models of SCI and some of them have been considered for clinical trials. However, evaluation of the effect of such interventions on autonomic functions has received only rudimentar

Thesis (PhD)--University of Stellenbosch, 2005.<br>ENGLISH ABSTRACT: Problem statement For utilitarians, human beings have intrinsic moral significance based on only two acquired characteristics: sentience, or the ability to suffer, and psychological personhood. Sentience is the entrance-requirement for moral significance, but does not justify a "right to life" claim; at most a "right" not to suffer. Personhood, described as some sort of self-conscious awareness with a concept of the future, may justify a "right to life" claim. However, since personhood is absent in prenatal beings, and

Hypertension is associated with marked cardiac sympathetic over-activity and end organ hyper-responsiveness. The sympathetic dysfunction is caused by aberrant calcium (Ca<sup>2+</sup>) handling resulting in enhanced neurotransmission. However, it remains unclear whether the sympathetic neuron or the myocytes is the primary driver behind the initiation and maintenance of the autonomic phenotype. The work in this thesis characterises the Ca<sup>2+</sup> dysfunction and regulation at the membrane level.

Abstract:

L'industria automobilistica è in anticipo rispetto all'aviazione per quanto riguarda l’applicazione del sistema di propulsione elettrico puro. Anche se esistono similitudini tra i due settori, differenze come intervalli di temperature operative, limiti di peso e requisiti di sicurezza rendono necessario lo studio in modo separato dello spazio di progettazione del sistema di propulsione. Gli strumenti di progettazione degli aeromobili tradizionali, non sono in grado di spiegare e modellare i significativi cambiamenti inerenti agli aeromobili progettati attorno ai sistemi di propulsione elettric

Abstract:

Dans un avion, un hélicoptère ou un lanceur actuel, des milliers de capteurs, pour la plupart non critiques sont utilisés pour la mesure de divers paramètres (températures, pressions, positions...) Les résultats sont ensuite acheminés par des fils vers les calculateurs de bord qui les traitent. Ceci implique la mise en place de centaines de kilomètres de câbles (500 km pour un avion de ligne) dont le volume est considérable. Il en résulte une grande complexité de conception et de fabrication, des problèmes de fiabilité, notamment au niveau des connexions, et une masse importante. Par ailleurs

Abstract:

Les maladies hématologiques, telles que les leucémies et les lymphomes, sont parmi les cancers les plus fréquents chez les jeunes adultes. Bien que la greffe de cellules souches (GCS) permet de traiter ceux-ci, de nombreux effets secondaires peuvent découler de ce traitement. Il est ainsi souhaité que les jeunes adultes développent une expertise quant à l’autogestion de leurs symptômes. Pourtant, peu de connaissances existent quant à leurs expériences d’autogestion. Cette étude avait pour but de décrire les expériences d’apprentissage quant à l’autogestion de jeunes adultes (18-39 ans) ayan

Abstract:

We hypothesize that brain glycogen, a stored form of glucose, may provide fuel for the brain conferring both negative and positive effects throughout the brain. The over accumulation of brain glycogen, or supercompensation, is hypothesized to exacerbate hypoglycemia associated autonomic failure (HAAF), promote memory and learning, and reduce neuron cell death during severe episodes of hypoglycemia. It was determined that brain glycogen supercompensation does occur in the mouse 6 hours following single and recurrent hypoglycemic episodes, but it is not likely a significant mechanism behind HAAF

Abstract:

Background: type 2 diabetes is determined by a reduction of β cell mass and function besides a defect in insulin sensitivity. It was demonstrated that pancreatic islets are innervated by sympathetic nervous system (SNS) and parasympathetic nervous system (PNS) fibers and autonomic function contributes to the regulation of glucose homeostasis. An alteration in neuronal control of β cell function could be involved in the pathogenesis of the type 2 diabetes. Aim: we focused on finding a possible association between autonomic function and the different parameters that describe β cell function in

Indiana University-Purdue University Indianapolis (IUPUI)<br>Autonomic innervation of the heart begins in utero and continues during the neonatal phase of life. A balance between the sympathetic and parasympathetic arms of the autonomic nervous system is required to regulate heart rate as well as the force of each contraction. Our lab studies the development of sympathetic innervation of the early postnatal heart in a conditional knockout (cKO) of Src homology protein tyrosine phosphatase 2 (Shp2). Shp2 is a ubiquitously expressed non-receptor phosphatase involved in a variety of cellular func

Abstract:

Indiana University-Purdue University Indianapolis (IUPUI)<br>The heart is a complex organ that is composed of numerous cell types, which must integrate their programs for proper specification, differentiation, and cardiac morphogenesis. During cardiac development the basic helix-loop-helix transcription factor Hand2 is dynamically expressed within the endocardium and extra-cardiac lineages such as the epicardium, cardiac neural crest cells (cNCCs), and NCC derived components of the autonomic nervous system. To investigate Hand2 function within these populations we utilized multiple murine Hand

Le génie tissulaire en créant, réparant ou améliorant la fonction des tissus est une option prometteuse afin de diminuer la mortalité associée à ces pathologies. L’objectif global de mon projet de recherche était de développer des outils et d’étudier l’impact fonctionnel des différents stimuli (mécanique et électrique) de l’environnement cardiaque dans le but de définir des conditions optimisées de culture pour la fabrication
