Análisis del somatotipo de jugadores juveniles de fútbol asociación

The anthropometric characteristics of the subjects in association football were rarely considered in the selection of young soccer players in relation to their positions on the pitch. At present, in this sport it is becoming more and more frequent, as well as adding variables that contribute to the improvement of sports performance. Therefore, the main objective of this research is to identify and analyze the somatotype of amateur level players enrolled in the delfines academy who participate in the Veracruz soccer league, within the selection criteria of the participants is that they are in the age range of 14-17 years, they were evaluated for body composition through the bioimpedance technique (tanita tbf 300a, manual), with this the values ​​of weight, height, and BMI were obtained. Likewise, the anthropometry technique was obtained to obtain a complete profile of each player taking as a reference the calculation of the Heath - Carter somatotype, one of the results obtained is the prevalence of the endomorph somatotype for the forwards (2.87 ± 0. 76), defenders (2.99±0.55) and midfielders (2.55±0.47) and mesomorph: forwards (5.34±1.17), defenders (5.86±1.55) and midfielders (4.71±0.67), It was shown that the means present less mesomorphy and greater ectomorphy with (3.64±1.29). It is concluded from the results obtained that the predominance is of the balanced mesomorphic component, a situation that coincides with the results of other investigations, where the players of the amateur sector and professional soccer players according to the position they occupy on the pitch presenting a somatotype similar to those found in the studyLas características antropométricas de los sujetos en el fútbol asociación pocas veces eran consideradas en la selección de los jóvenes futbolistas en relación con sus posiciones dentro del terreno de juego. En la actualidad, en este deporte se hace cada vez más frecuente, así como sumar variables que coadyuvan a la mejora del rendimiento deportivo. Por tanto, el objetivo principal de esta investigación es identificar y analizar el somatotipo de jugadores de nivel amateur inscritos en la academia delfines que participa en la liga veracruzana de fútbol, dentro de los criterios de selección de los participantes es que estén en el rango de edad de 14-17 años, a ellos se les evaluación de composición corporal a través de la técnica de bioimpedancia (tanita tbf 300a, manual), con ello se obtuvieron los valores de peso, talla, IMC. Así mismo se utilizó la técnica de antropometría para obtener un perfil completo de cada jugador tomando como referencia el cálculo del somatotipo de Heath – Carter, alguno de los resultados obtenidos es la prevalencia del somatotipo de endomorfo para los delanteros (2,87±0,76), defensas (2.99±0,55) y medios campistas (2,55±0,47) y mesomorfo: delanteros (5,34±1,17), defensas (5,86±1,55) y medios campistas (4,71±0,67), Se observó que los medios presentan menor mesomorfia y mayor ectomorfia con (3,64 ±1,29). Se concluye por los resultados obtenidos que la predominancia es del componente mesomórfico balanceado, situación que coinciden con los resultados de otras investigaciones, donde los jugadores del sector amateur y jugadores de fútbol profesional de acuerdo a la posición que ocupan en el terreno de juego presentan un somatotipo similar a los hallazgos en el estudio

Phase I clinical trial in healthy adults of a nasal vaccine candidate containing recombinant hepatitis B surface and core antigens

SummaryBackgroundThe nasal vaccine candidate (NASVAC), comprising hepatitis B virus (HBV) surface (HBsAg) and core antigens (HBcAg), has been shown to be highly immunogenic in animal models.MethodsA phase I double-blinded, placebo-controlled randomized clinical trial was carried out in 19 healthy male adults with no serologic markers of immunity/infection to HBV. This study was aimed at exploring the safety and immunogenic profile of nasal co-administration of both HBV recombinant antigens. The trial was performed according to Good Clinical Practice guidelines. Participants ranged in age from 18 to 45 years and were randomly allocated to receive a mixture of 50μg HBsAg and 50μg HBcAg or 0.9% physiologic saline solution, as a placebo, via nasal spray in a five-dose schedule at 0, 7, 15, 30, and 60 days. A total volume of 0.5ml was administered in two dosages of 125μl per nostril. Adverse events were actively recorded 1h, 6h, 12h, 24h, 48h, 72h, 7 days and 30 days after each dose. Anti-HBs and anti-HBc titers were evaluated using corresponding ELISA kits at days 30 and 90.ResultsThe vaccine candidate was safe and well tolerated. Adverse reactions included sneezing (34.1%), rhinorrhea (12.2%), nasal stuffiness (9.8%), palate itching (9.8%), headache (9.8%), and general malaise (7.3%). These reactions were all self-limiting and mild in intensity. No severe or unexpected events were recorded during the trial. The vaccine elicited anti-HBc seroconversion in 100% of subjects as early as day 30 of the immunization schedule, while a seroprotective anti-HBs titer (≥10IU/l) was at a maximum at day 90 (75%). All subjects in the placebo group remained seronegative during the trial.ConclusionThe HBsAg–HBcAg vaccine candidate was safe, well tolerated and immunogenic in this phase I study in healthy adults. To our knowledge, this is the first demonstration of safety and immunogenicity for a nasal vaccine candidate comprising HBV antigens

Gene expression profile of cervical and skin tissues from human papillomavirus type 16 E6 transgenic mice

<p>Abstract</p> <p>Background</p> <p>Although K14E6 transgenic mice develop spontaneous tumors of the skin epithelium, no spontaneous reproductive tract malignancies arise, unless the transgenic mice were treated chronically with 17β-estradiol. These findings suggest that E6 performs critical functions in normal adult cervix and skin, highlighting the need to define E6-controlled transcriptional programs in these tissues.</p> <p>Methods</p> <p>We evaluated the expression profile of 14,000 genes in skin or cervix from young K14E6 transgenic mice compared with nontransgenic. To identify differentially expressed genes a linear model was implemented using R and the LIMMA package. Two criteria were used to select the set of relevant genes. First a set of genes with a Log-odds ≥ 3 were selected. Then, a hierarchical search of genes was based on Log Fold Changes.</p> <p>Results</p> <p>Microarray analysis identified a total of 676 and 1154 genes that were significantly up and down-regulated, respectively, in skin from K14E6 transgenic mice. On the other hand, in the cervix from K14E6 transgenic mice we found that only 97 and 252 genes were significantly up and down-regulated, respectively. One of the most affected processes in the skin from K14E6 transgenic mice was the cell cycle. We also found that skin from transgenic mice showed down-regulation of pro-apoptotic genes and genes related to the immune response. In the cervix of K14E6 transgenic mice, we could not find affected any gene related to the cell cycle and apoptosis pathways but did observe alterations in the expression of immune response genes. Pathways such as angiogenesis, cell junction and epidermis development, also were altered in their gene expression profiles in both tissues.</p> <p>Conclusion</p> <p>Expression of the HPV16 E6 oncoprotein in our model alters expression of genes that fell into several functional groups providing insights into pathways by which E6 deregulate cell cycle progression, apoptosis, the host resistance to infection and immune function, providing new opportunities for early diagnostic markers and therapeutic drug targets.</p

Impact of Human Management on the Genetic Variation of Wild Pepper, Capsicum annuum var. glabriusculum

Management of wild peppers in Mexico has occurred for a long time without clear phenotypic signs of domestication. However, pre-domestication management could have implications for the population's genetic richness. To test this hypothesis we analysed 27 wild (W), let standing (LS) and cultivated (C) populations, plus 7 samples from local markets (LM), with nine polymorphic microsatellite markers. Two hundred and fifty two alleles were identified, averaging 28 per locus. Allele number was higher in W, and 15 and 40% less in LS and C populations, respectively. Genetic variation had a significant population structure. In W populations, structure was associated with ecological and geographic areas according to isolation by distance. When LM and C populations where included in the analysis, differentiation was no longer apparent. Most LM were related to distant populations from Sierra Madre Oriental, which represents their probable origin. Historical demography shows a recent decline in all W populations. Thus, pre-domestication human management is associated with a significant reduction of genetic diversity and with a loss of differentiation suggesting movement among regions by man. Measures to conserve wild and managed populations should be implemented to maintain the source and the architecture of genetic variation in this important crop relative

Transancestral mapping and genetic load in systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is an autoimmune disease with marked gender and ethnic disparities. We report a large transancestral association study of SLE using Immunochip genotype data from 27,574 individuals of European (EA), African (AA) and Hispanic Amerindian (HA) ancestry. We identify 58 distinct non-HLA regions in EA, 9 in AA and 16 in HA (∼50% of these regions have multiple independent associations); these include 24 novel SLE regions (P<5 × 10-8), refined association signals in established regions, extended associations to additional ancestries, and a disentangled complex HLA multigenic effect. The risk allele count (genetic load) exhibits an accelerating pattern of SLE risk, leading us to posit a cumulative hit hypothesis for autoimmune disease. Comparing results across the three ancestries identifies both ancestry-dependent and ancestry-independent contributions to SLE risk. Our results are consistent with the unique and complex histories of the populations sampled, and collectively help clarify the genetic architecture and ethnic disparities in SLE.info:eu-repo/semantics/publishedVersio
