Association between agility and speed with changes of direction in young players

Identificar factores asociados al máximo rendimiento en el fútbol posibilitará mejorar el proceso de planificación deportiva en etapas tempranas. Este estudio tuvo como objetivo determinar la asociación entre la agilidad y la velocidad con cambios de dirección (VCD) en jóvenes futbolistas (JF). Participaron voluntariamente dieciocho hombres entre los 10 y 13 años los cuales aplicaron el test de 20 metros con cambios de dirección (T20CD) y el test de agilidad Illinois (TAI). El análisis estadístico se realizó en el IBM SPSS V.22 en el cual se fijó para la significancia un p0,05) y no normal en TAI (p<0,05), el coeficiente correlacional de Spearman (r = 0,06; p = 0,8) evidenció una relación poco significativa (p<0,05). Por lo tanto se concluye que no existe asociación significativa entre la agilidad y la VCD en JF

Asociación entre la agilidad y la velocidad con cambios de dirección en jóvenes futbolistas

Identify factors associated with maximum performance in soccer will enable streamlining the sports planning in the early stages. This study was objective to determine the association between agility and speed with changes in direction (SCD) in young soccer players (YS). Participated voluntarily eighteen men between 10 and 13 years which applied the test of 20 meters with changes of direction (T20CD) and the test of agility Illinois (TAI). The statistical analysis was performed in the IBM SPSS V.22 in which a is set to the significance a p&lt;0,05. The results in Shapiro-Wilk normality test indicated normality of data in T20CD (p&gt;0,05) and not normal in TAI (p&lt;0,05), the coeficient correlational of Spearman (r = 0,06; p = 0,8) was a little significant relationship (p&lt;0,05). Therefore it is concluded that there is no significant association between agility and SCD in YS.Identificar factores asociados al máximo rendimiento en el fútbol posibilitará mejorar el proceso de planificación deportiva en etapas tempranas.

Empty Urbanism: the bursting of the Spanish housing bubble

The depth of the Spanish housing crisis manifests itself in the collapse of construction activity and in the amount of housing and land stocks. The geography of the crisis shows its widespread nature, and the intensity of the previous bubble explains spatial differences. Resulting from this collapse are some problematic areas of 'empty urbanism'. An enormous land bubble, emerging from the peculiar Spanish urban development model, was a key factor in the impacts - caused by the crisis - on the territory and land-use plans. The crisis has demonstrated the unsustainability of this and the urgency of change in the existing land-use plans

Extracellular Tuning of Mitochondrial Respiration Leads to Aortic Aneurysm

Marfan syndrome (MFS) is an autosomal dominant disorder of the connective tissue caused by mutations in the FBN1 (fibrillin-1) gene encoding a large glycoprotein in the extracellular matrix called fibrillin-1. The major complication of this connective disorder is the risk to develop thoracic aortic aneurysm. To date, no effective pharmacologic therapies have been identified for the management of thoracic aortic disease and the only options capable of preventing aneurysm rupture are endovascular repair or open surgery. Here, we have studied the role of mitochondrial dysfunction in the progression of thoracic aortic aneurysm and mitochondrial boosting strategies as a potential treatment to managing aortic aneurysms.Fondo de Investigacion Sanitaria del Instituto de Salud Carlos III (PI16/188, PI19/855), the European Regional D evelopment Fund, and the European Commission through H2020-EU.1.1, European Research Council grant ERC-2016-StG 715322-EndoMitTalk, and Gobierno de Espana SAF2016-80305P.

Persistence of COVID-19 Symptoms after Recovery in Mexican Population

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the coronavirus disease (COVID-19), a highly contagious infectious disease that has caused many deaths worldwide. Despite global efforts, it continues to cause great losses, and leaving multiple unknowns that we must resolve in order to face the pandemic more effectively. One of the questions that has arisen recently is what happens, after recovering from COVID-19. For this reason, the objective of this study is to identify the risk of presenting persistent symptoms in recovered from COVID-19. This case-control study was conducted in one state of Mexico. Initially the data were obtained from the participants, through a questionnaire about symptoms that they had at the moment of the interview. Initially were captured the collected data, to make a dataset. After the pre-processed using the R project tool to eliminate outliers or missing data. Obtained finally a total of 219 participants, 141 recovered and 78 controls. It was used confidence level of 90% and a margin of error of 7%. From results it was obtained that all symptoms have an associated risk in those recovered. The relative risk of the selected symptoms in the recovered patients goes from 3 to 22 times, being infinite for the case of dyspnea, due to the fact that there is no control that presents this symptom at the moment of the interview, followed by the nausea and the anosmia with a RR of 8.5. Therefore, public health strategies must be rethought, to treat or rehabilitate, avoiding chronic problems in patients recovered from COVID-19

Copper, zinc, mercury and arsenic content in Micropogonias furnieri and Mugil platanus of the Montevideo coastal zone, Río de la Plata

Abstract Metals (Cu, Zn, Hg) and metalloid (As) concentrations were measured in Micropogonias furnieri and Mugil platanus caught in three areas along the Montevideo coastal zone during winter 2010, spring 2010 and 2011. Compared to previous studies conducted in the zone, both species showed higher (for Cu), similar (for Zn) or lower (for Hg) concentrations. The highest Hg values were found in the M. furnieri of Montevideo bay. There was no spatial variation in Cu, Zn, and As concentrations in muscle, likely due to the high mobility of both species. However, the Cu content in the liver of M. furnieri was higher in fish from the West zone. Cu, Zn and As found in the liver of M. platanus were much higher than in that of M. furnieri. A functional relationship between muscle levels of Zn and Hg and fish length of M. furnieri indicates bioaccumulation of these metals. According to the results, M. furnieri may be used as a temporal bioindicator for Hg, but not as a spatial bioindicator. Mercury levels were below the maximum safety level based on international standard values for human consumption
