Maturation of barley cysteine endopeptidase expressed in Trichoderma reesei is distorted by incomplete processing

2002

Maturation of barley cysteine endopeptidase B (EPB) in Trichoderma reesei was studied with metabolic inhibitors, Western blotting, and immuno microscopy. The inactive 42-kDa recombinant EPB proprotein, first detected in apical cells, was sequentially processed in a time-dependent manner to a secreted polypeptide of 38.5 kDa, and thereafter, to polypeptides of 37.5, 35.5, and 32 kDa exhibiting enzyme activity both in the hyphae and culture medium. The sizes of the different forms of recombinant EPB were in accordance with molecular masses calculated from the deduced amino acid sequence, assuming cleavage at four putative Kex2p sites present in the 42-kDa proprotein. Both the liquid and the z…

Influence of fat mass for the VO2max and ventilatory thresholds in young athletes of endurance sport specialties

2016

[Resumen] El objetivo del estudio es analizar la influencia de la masa grasa total y su % respecto al peso corporal total, así como la masa grasa regionalizada (Σ pliegues tronco, Σ pliegues abdomen, cociente TS/TI, phantom (Ph) de los pliegues) y su % respecto a la masa grasa total, en relación al VO2max y los Umbrales Ventilatorios (VT1 y VT2) en jóvenes deportistas en función de su especialidad deportiva y grupo de edad. La muestra está compuesta por 400 deportistas de ambos sexos del Centro de Tecnificación de Cheste (Valencia) clasificados en 3 grupos de edad: 0,05) entre atletismo y natación. Para el caso de los grupos de edad se han encontrado diferencias significativas (p0,05) entre…

Effects of a Postural Exercise Program on Vertical Jump Height in Young Female Volleyball Players with Knee Valgus

2022

Background: Although a knee valgus position is related to the increase in injury risk in volleyball players, there is a lack of studies on the relationship between knee valgus and vertical jump (VJ) performance. Hence, the aim of this study was to investigate the effects of a postural exercise program on VJ height in young female volleyball players with knee valgus. Methods: This pilot study included 19 young female volleyball players divided into the following groups: the Valgus Experimental Group (VEG); the Valgus Control Group (VCG); and the Neutral Control Group (NCG). All three groups carried out the same volleyball training program. In addition, only the VEG underwent a 3-month postur…

Low frequency gray-body factors and infrared divergences: rigorous results

2015

Formal solutions to the mode equations for both spherically symmetric black holes and Bose-Einstein condensate acoustic black holes are obtained by writing the spatial part of the mode equation as a linear Volterra integral equation of the second kind. The solutions work for a massless minimally coupled scalar field in the s-wave or zero angular momentum sector for a spherically symmetric black hole and in the longitudinal sector of a 1D Bose-Einstein condensate acoustic black hole. These solutions are used to obtain in a rigorous way analytic expressions for the scattering coefficients and gray-body factors in the zero frequency limit. They are also used to study the infrared behaviors of …

Nonperturbative structure of the ghost-gluon kernel

2019

The ghost-gluon scattering kernel is a special correlation function that is intimately connected with two fundamental vertices of the gauge sector of QCD: the ghost-gluon vertex, which may be obtained from it through suitable contraction, and the three-gluon vertex, whose Slavnov-Taylor identity contains that kernel as one of its main ingredients. In this work we present a detailed nonperturbative study of the five form factors comprising it, using as starting point the `one-loop dressed' approximation of the dynamical equations governing their evolution. The analysis is carried out for arbitrary Euclidean momenta, and makes extensive use of the gluon propagator and the ghost dressing funct…

Silk-based matrices and c-Kit positive cardiac progenitor cells for a cellularized silk fibroin scaffold: study of an in vivo model.

2022

The production of a cellularized silk fibroin scaffold is very difficult because it is actually impossible to differentiate cells into a well-organized cardiac tissue. Without vascularization, not only do cell masses fail to grow, but they may also exhibit an area of necrosis, indicating a lack of oxygen and nutrients. In the present study, we used the so-called tyrosine protein kinase kit (c-kit)-positive cardiac progenitor cells (CPCs) to generate cardiac cellularized silk fibroin scaffolds, multipotent cells isolated from the adult heart to date that can show some degree of differentiation toward the cardiac phenotype. To test their ability to differentiate into the cardiac phenotype in …

A 47-Year Comparison of Lower Body Muscular Power in Spanish Boys: A Short Report

2020

Much of the evidence examining temporal trends in fitness among youth has found a decrease in measures of muscular strength and muscular power over recent decades. The aim of this study was to examine trends in lower body muscular power in Spanish boys over 47 years. In 1969 140 boys (10–11 years; body mass index = 19.24, SD = 2.91 kg/m2) and in 2016, 113 boys (10–11 years; body mass index = 19.20, SD = 3.15 kg/m2) were recruited. Lower body power was assessed using the vertical jump (VJ) and standing long jump (SLJ) tests. Significant differences and a large effect size were shown between groups in the SLJ (p = 0.001; d = 0.94) and the VJ (p = 0.001; d = 0.66). SLJ data in 1969 were higher…

Going, Returning, Rising. The Movement of the Organs in the Mesopotamian Anatomy

2019

Although many assyriological studies have been done on internal organs in the Mesopotamian worldview, the pathologies associated with them, and their metaphorical and ideological value, little attention have been paid to the fact that, sometimes, internal organs are associated with verbs of movement. Perhaps, this limited regard can be attributed to the assyriological look at the Mesopotamian body being shaped by the modern biomedicine. According to biomedicine, in fact, the human internal anatomy is composed of a series of organs which stay fixed in their positions. On the contrary, I want to show how the internal organs in Mesopotamian anatomy are thought as capable to move. I will demons…

Emancipation Through Sports: Doctors and the Rise of the Female Body in Finlandc.1900–1920

2012

While the cultural history of body and sports have become well-established fields of historical studies since the 1980s, it has been demonstrated that medical practice has functioned as a moral discourse which produces a regulation of the female body. It has been realised that theories (e.g. of ‘degeneration’) concerning the functioning of the human body bore a great significance to planning and defining the programmes of physical education, gymnastics and sports in the spirit of muscular nationalism. Doctors studying human physiology and training were eager to control not only the female body but also the mind of a gymnast or a sportswoman. This is what happened also in Finland from the la…
