La práctica deportiva del judo: análisis sociológico de su implantación y desarrollo en la sociedad valenciana
2010
Este artículo es un resumen de la tesis doctoral que se leyó en el año 2005 en el Departamento de Sociología y Antropología Social de la Universitat de València. El objetivo del análisis se plantea desvelar, desde una perspectiva sociohistórica, la irrupción del judo en la sociedad valenciana y su evolución hasta nuestros días en el contexto de una sociedad ampliamente deportivizada. Desde una mirada cualitativa, fundamentada en el análisis de los discursos producidos por informantes clave, se aborda la imagen social del judo como cultura cambiante, la forma en que se organiza su práctica y los confines que la delimitan en el contexto de la actual sociedad postindustrial y postmoderna.
Attention to diversity in Madrilenian classrooms. Teachers’ opinions
2022
City marathons have evolved and grown exponentially in type and popularity, in their managerial complexity, and in terms of their financial impact on their host cities and the attraction of corporate sponsors. Most of the research on city marathons has focused on evaluating their broad economic, urban, tourist, social, sporting, and symbolic effects on host cities. However, less attention has been paid to analyzing key strategic decisions that could account for the evolution and growth of specific marathons and their influences on their management and success. This article, which addresses the cases of the Bank of America Chicago Marathon and the Marathon Valencia Trinidad Alfonso, examines…
von Hippel-Lindau Protein-Mediated Repression of Tumor Necrosis Factor Alpha Translation Revealed through Use of cDNA Arrays
2003
Based on evidence that the von Hippel-Lindau (VHL) tumor suppressor protein is associated with polysomes and interacts with translation regulatory factors, we set out to investigate the potential influence of pVHL on protein translation. To this end, renal cell carcinoma (RCC) cells that either lacked pVHL or expressed pVHL through stable transfection were used to prepare RNA from cytosolic (unbound) and polysome-bound fractions. Hybridization of cDNA arrays using RNA from each fraction revealed a subset of transcripts whose abundance in polysomes decreased when pVHL function was restored. The tumor necrosis factor alpha (TNF-alpha) mRNA was identified as one of the transcripts that prefere…
Impact of freezing rate on electrical conductivity of produce
2013
The aim of this work was to compare the effects of freezing rate on electrical conductivity of potatoes, carrots and apples. Electrical conductivity tests were conducted on a custom ohmic cell while samples texture was measured by means of a universal testing machine. The raw un-pretreated samples were used as control. This study showed that freezing pre-treatments lead to differences in electrical conductivity of considered samples, producing structural damage, the latter being relatively more severe when the tested products undergo ohmic treatment.
Specific sequence elements in the 5′ untranslated regions of rbcL and atpB gene mRNAs stabilize transcripts in the chloroplast of Chlamydomonas reinh…
2001
Using a series of point mutations in chimeric reporter gene constructs consisting of the 5' regions of the Chlamydomonas chloroplast rbcL or atpB genes fused 5' to the coding sequence of the bacterial uidA (GUS) gene, RNA-stabilizing sequence elements were identified in vivo in the 5' untranslated regions (5' UTRs) of transcripts of the chloroplast genes rbcL and atpB in Chlamydomonas reinhardtii. In chimeric rbcL 5' UTR:GUS transcripts, replacement of single nucleotides in the 10-nt sequence 5'-AUUUCCGGAC-3', extending from positions +38 to +47 relative to the transcripts' 5' terminus, shortened transcript longevity and led to a reduction in transcript abundance of more than 95%. A similar…
Changes in the 5?-untranslated region of the rbcL gene accelerate transcript degradation more than 50-fold in the chloroplast of Chlamydomonas reinha…
2003
Using uidA (beta-glucuronidase; GUS) reporter gene constructs, the 5'-untranslated region (UTR) of the Chlamydomonas chloroplast rbcL gene was screened by deletion and mutational analysis for the presence of a promoter element that previous studies implied to reside within the first 63 base pairs of the UTR. Deleting a large segment of the rbcL 5'UTR in a 3'--5' direction to position +36, changing the remaining 36 base pairs at the 5' end of the UTR, and increasing by five base pairs the distance between the rbcL 5'UTR and the basic promoter element located at position -10 did not abolish transcription from the basic rbcL promoter. It is concluded that the apparent loss of transcriptional a…
The 3'-UTR of the mRNA coding for the major protein kinase C substrate MARCKS contains a novel CU-rich element interacting with the mRNA stabilizing …
2003
The expression of the major protein kinase C substrate MARCKS (myristoylated alanine-rich C kinase substrate) is controlled by the stability of its mRNA. While the MARCKS mRNA is long living in quiescent fibroblasts (t1/2 = 14 h), its half-life time is drastically reduced (t1/2 = 2 h) in cells treated with phorbol esters to activate protein kinase C (PKC) or treated with growth factors. In a first step to study the underlying mechanism we identified both a cis-element on the MARCKS mRNA and the corresponding trans-acting factors. Fusing the complete 3'-UTR or specific regions of the 3'-UTR of the MARCKS gene to a luciferase reporter gene caused a drastic decrease in luciferase expression to…
3'-Untranslated regions of oxidative phosphorylation mRNAs function in vivo, as enhancers of translation
2000
Recent findings have indicated that the 3´-untranslated region (3´-UTR) of the mRNA encoding the β-catalytic subunit of the mitochondrial H+-ATP synthase has an in vitro translation-enhancing activity (TEA) [Izquierdo and Cuezva, Mol. Cell. Biol. (1997) 17, 5255–5268; Izquierdo and Cuezva, Biochem. J. (2000) 346, 849–855]. In the present work, we have expressed chimaeric plasmids that encode mRNA variants of green fluorescent protein in normal rat kidney and liver clone 9 cells to determine whether the 3´-UTRs of nuclear-encoded mRNAs involved in the biogenesis of mitochondria have an intrinsic TEA. TEA is found in the 3´-UTR of the mRNAs encoding the α- and β-subunits of the rat H+-ATP syn…

The pathologies located at shoulder can be caused by misuse or continued implementation of a sporting practice or physical activity. These pathologies are second position in the ranking of Traumatologics and Orthopedic Clinicals (Windt, Koes, De Jong & Bouter, 1995). Shoulder’s muscle injuries can occur when the arm is in a position that exceeds normal, this fact is repeated in sport, may be the repetition of the hand signal of the inductor problem (Kapandji, 2006). Given the importance of muscle function of the shoulder joint, along the existing boom of new techniques in the specific muscle activation has been carried out an experimental study using a " Test neuro proprioceptive response "…
Report WS6: Immigration and new inhabitants in the Gateway Cities
2012
It is in the last years that the planning discipline has fully recognized immigration issues as decisive for their role both in the urban studies and in the policy design. Nowadays, in Italy and Europe, the shifting social composition of the cities asks the planner for new cognitive instruments and new strategies for the interventions on urban systems. The present report resumes the results of the workshop “Immigration and new inhabitants in the gateway cities” which took place inside the IX Biennial of Towns and Town Planners of Europe, held in Genoa in September 2011. In the two days of debate, a number of Italian and European examples has been presented: the report underlines three issue…
