Tiam1 as a Signaling Mediator of Nerve Growth Factor-Dependent Neurite Outgrowth
2010
Nerve Growth Factor (NGF)-induced neuronal differentiation requires the activation of members of the Rho family of small GTPases. However, the molecular mechanisms through which NGF regulates cytoskeletal changes and neurite outgrowth are not totally understood. In this work, we identify the Rac1-specific guanine exchange factor (GEF) Tiam1 as a novel mediator of NGF/TrkA-dependent neurite elongation. In particular, we report that knockdown of Tiam1 causes a significant reduction in Rac1 activity and neurite outgrowth induced by NGF. Physical interaction between Tiam1 and active Ras (Ras- GTP), but not tyrosine phosphorylation of Tiam1, plays a central role in Rac1 activation by NGF. In add…
Trait-specific tracking and determinants of body composition: a 7-year follow-up study of pubertal growth in girls
2009
BACKGROUND: Understanding how bone (BM), lean (LM) and fat mass (FM) develop through childhood, puberty and adolescence is vital since it holds key information regarding current and future health. Our study aimed to determine how BM, LM and FM track from prepuberty to early adulthood in girls and what factors are associated with intra- and inter-individual variation in these three tissues. METHODS: The study was a 7-year longitudinal cohort study. BM, LM and FM measured using dual-energy X-ray absorptiometry, self-reported dietary information, leisure time physical activity (LTPA) and other factors were assessed one to eight times in 396 girls aged 10 to 13 years (baseline), and in 255 moth…

The territorial dimension in the EU programming and the New Framework for Public Policies: Territorial Tural Development, CAP Reform and new LEADER
2012
Lo que venimos denominando como perspectiva territorial del desarrollo es un fenómeno bastante reciente en el contexto de la Unión Europea, de apenas dos décadas. En esencia esta perspectiva territorial del desarrollo se ha centrado en un enfoque local de los procesos de desarrollo en las áreas rurales, de la mano, principalmente, de instrumentos como LEADER. La necesidad de incorporar la dimensión territorial a los procesos de desarrollo proviene no solo del éxito global de estos instrumentos, sino también por el convencimiento de que puede constituir un elemento fundamental de cara a la cohesión económica y social en el seno de la UE. Avances recientes, como el Libro Verde de la Cohesión …
Study on the Influence of Economic and Social Factors on the Financing of National Defense
2020
In the Romanian literature and current research, the financing of national defense is a less debated topic. Most studies are conducted mainly for developed countries, which also have the most advanced military systems and focus only on the correlation between military spending and the economy. The objective of the paper is to investigate the correlation between the evolution of military spending in Romania during 1919-2012 on the one hand, and economic, political and social factors, on the other. The empirical study performed used the linear regression model, estimated by the least squares method (OLS), using the statistical software EViews 10. The results of the study showed that the level…

Antitumor Effect of Cabozantinib in Bone Metastatic Models of Renal Cell Carcinoma
2021
Background: The presence of bone metastases in renal cell carcinoma (RCC) negatively affects patients’ survival. Data from clinical trials has highlighted a significant benefit of cabozantinib in bone metastatic RCC patients. Here, we evaluated the antitumor effect of cabozantinib in coculture models of renal cell carcinoma (RCC) and osteoblasts (OBs) to investigate whether and how its antiproliferative activity is influenced by OBs. Methods: Bone/RCC models were generated, coculturing green fluorescent protein (GFP)-tagged Caki-1 and 786-O cells with human primary OBs in a “cell–cell contact” system. RCC proliferation and the OB molecular profile were evaluated after the cabozantinib treat…
Firm growth and profitability : The role of age and size in shifts between growth–profitability configurations
2023
To investigate the routes toward profitable growth, this study partially replicates and extends the work of Davidsson et al. (2009) on firm growth–profitability dynamics with multi-industry data on over 66,000 Finnish firms. The results support prior findings on initial profitability being more important than initial growth for achieving high performance in both performance dimensions. Additional investigations on the role of firm age and size reveal further interesting dynamics: Very small young firms face fewer risks from growing at a low profitability level than other firms, and the benefits of firm size for future performance depend on the firm's current profitability. The results advan…
The Village of the Year Competition Constructing an Ideal Model of a Rural Community in Finland
2016
The Village Action Association of Finland (SYTY) organizes the Village of the Year competition annually to award active rural communities. The competition has taken place since 1985, but after the village action movement was integrated into Finnish rural policy networks in the 1990s, it also became a part of rural policy instruments. The competition can be considered a governing technique that constructs norms and an ideal model for rural communities to pursue. In this article, I study the representation of an ideal rural community by analysing the criteria of the competition. I also look for changes to see whether the integration of the village action movement into rural policy is reflecte…
Physiological and Molecular Adaptations to Strength Training
2019
High muscle contraction forces that lead to gains in muscle function, size, and strength characterize resistance exercise training. The purpose of this chapter is to outline the adaptations in myofiber size and metabolism that occur by stimuli of hormones and local growth factors, mechanical and metabolic stress of muscle tissue, and myofibrillar disruptions induced by a resistance exercise bout. The chapter will highlight the network of intracellular pathways (including mTOR signaling) that ultimately lead to increases in gene expression and protein synthesis. Accumulation of acute exercise responses by systematic training over time modulate the muscle proteome that can be observed as chan…
