El presente artículo de investigación presenta los resultados de un estudio cuyo objetivo consistió en analizar las estrategias cognitivas y el componente motivacional del aprendizaje en estudiantes de primer curso de la facultad de medicina de Zaragoza mediante el Cuestionario de Motivación y Estrategias de Aprendizaje (MSLQ, Pintrich et al., 1991...

We evaluated the in vivo effects of melatonin treatment on oxidative damage in the liver in an experimental model of ischemia–reperfusion. A total of 37 male Sprague-Dawley rats were randomly divided into four groups: control, ischemia, ischemia + reperfusion, and ischemia + reperfusion + melatonin. Hepatic ischemia was maintained for 20 min, and t...

The enteric nervous system (ENS) is organized into two plexuses—submucosal and myenteric—which regulate smooth muscle contraction, secretion, and blood flow along the gastrointestinal tract under the influence of the rest of the autonomic nervous system (ANS). Interstitial cells of Cajal (ICCs) are mainly located in the submucosa between the two mu...

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease affecting motor neurons in the spinal cord, cerebral cortex, and medulla oblongata. Most patients present a clinical phenotype of classic ALS—with predominant atrophy, muscle weakness, and fasciculations—and survival of 3 to 5 years following diagnosis. In the present re...

Plasma lipid changes during incremental exercise are not well known. The aim of this study was to investigate the relationship among fat oxidation rate, plasma lipids, and hormone concentrations in well-trained athletes. Twenty-six trained triathletes completed a graded cycle ergometer test to exhaustion increasing by 0.5 W·kg−1 every 10 minutes. F...

Introducción: La aplicación de la teoría de los estilos de aprendizaje sirve para mejorar aquellos que tienen baja puntuación y capacitar a los estudiantes a aprender en las mejores condiciones en cualquier contexto. Para ello, la determinación de estilos por los distintos cuestionarios debe ser superponible. Por otro lado, la relación entre estilo...

The unintentional discovery of cirrhosis in a patient with prostate cancer lead us to enquire if some of the indexes/scored designed for the evaluation of liver fi brosis/cirrhosis, in Chronic Hepatitis C patients, could have helped us in the detection of incipient liver fi brosis, and its follow up, in this patient. We applied seven indexes/scores...

Introduction. About the style term there are different definitions and a lot of questionnaires to determine them; moreover, rankings are heterogeneous and meaning of different styles is not coincident. Subjects and methods. In order to clarify some points, this paper presents a new tool (CESEA) and compares the results obtained with those provided...

This study analyzes the relationship between hormonal changes induced by exercise and variations in trace elements associated with oxidative stress during incremental exercise. Nineteen well-trained endurance athletes performed a cycle ergometer test: after a warm-up of 10 min at 2.0 W kg(-1), workload increased by 0.5 W kg(-1) every 10 min until e...

Variants of the solute carrier SLC16A1 gene have been associated with alterations in MCT1 expression, due to a lactate (La-) transport deficiency across the cell membrane and a blood La- accumulation. The aim of the present study was to associate the allelic and genotypic frequencies of 1470T>A, 2917(1414) C>T and IVS3-17A>C variants relative to th...

This study analyzed the variation and relationship of several trace elements, metabolic substrates and stress hormones activated by exercise during incremental exercise. Seventeen well-trained endurance athletes performed a cycle ergometer test: after a warm-up of 10min at 2.0Wkg(-1), the workload was increased by 0.5Wkg(-1) every 10min until exhau...

In this study, we examined the relationship between plasma magnesium levels and hormonal variations during an incremental exercise test until exhaustion in 27, well-trained, male endurance athletes. After a warm-up of 10 min at 2 W/kg, the test began at an initial workload of 2.5 W/kg and continued with increments of 0.5 W/kg every 10 min until exh...

This chapter analyzes the learning styles and strategies, while highlighting the diversity of tools and the different results obtained with each of them. With regard to styles, there are more than 70 different tools, but not all of them have a similar exploratory orientation. Some of those studied by us are the CHAEA (Spanish Acronym of the Questio...

Abstract To investigate the effects of sulphurous mineral water (SMW) after a hydroponic treatment on muscle damage, antioxidant activity and peripheral blood changes induced by submaximal exercise. Thirty well-trained male triathletes were supplemented with SMW or placebo: 3 weeks of placebo, 30 days of wash out and 3 weeks of SMW. After both peri...

Introducción: El conocimiento metacognitivo que posee un individuo le permite sentirse más motivado y a medida que es más consciente de los mecanismos de autorregulación de los procesos que utiliza para el aprendizaje aprende mejor y más eficazmente. En este trabajo se analiza la relación existente entre los estilos de aprendizaje y el conocimiento...

The purpose of this study was to assess the effects of oral iron supplementation on hematological and iron metabolism in elite soccer players. Thirty-five members of the Real Zaragoza SAD soccer team took part in this study: group A (GA, n = 24; Spanish Premier League) took an oral iron supplement of 80 mg day(-1) for 3 weeks, and group B (GB, n = ...

The purpose of this study was to assess the effect of exercise intensity during an incremental exercise test on plasma Mg concentration in well-trained euhydrated athletes. Twenty-seven well-trained endurance athletes carried out a cycloergometer test: after a warm-up of 10 min at 2.0 W·kg(-1), the workload increased by 0.5 W·kg(-1) every 10 min un...

The purpose of this study was to assess the effect of relative exercise intensity on various plasma trace elements in euhydrated endurance athletes. Twenty-seven well-trained endurance athletes performed a cycloergometer test: after a warm-up of 10 min at 2.0 W kg⁻¹, workload increased by 0.5 W kg⁻¹ every 10 min until exhaustion. Oxygen uptake, blo...

PURPOSE: To assess the effects of a sprint distance duathlon laboratory simulation on FAToxr and CHOoxr. METHODS: 8 national level duathletes performed two incremental laboratory tests until exhaustion on a cycle ergometer (Initial workload: 60 W, stages: 30 W·min-1) and on a treadmill (Initial workload: 5 km·h-1, stages: 1 km·h-1) respectively to...

To assess which of the equations used to estimate mechanical power output for a wide aerobic range of exercise intensities gives the closest value to that measured with the SRM training system. Thirty four triathletes and endurance cyclists of both sexes (mean (SD) age 24 (5) years, height 176.3 (6.6) cm, weight 69.4 (7.6) kg and Vo(2)max 61.5 (5.9...

Metabolic therapy involves the administration of a substance normally found in the organism in order to enhance a metabolic reaction within the cell. This may be achieved in two ways: First, for some systems, a substance can be given to achieve greater-than-normal levels in the body so as to drive an enzymatic reaction in a preferred direction. Sec...

RESUMEN La esclerosis peritoneal encapsulante se ha asociado epidemiológicamente al empleo de acetato, líquidos hipertónicos o desinfectantes en la Diálisis Pe-ritoneal. Los mecanismos fisiopatológicos por los que estos agentes inducen la proliferación fibrosa no han sido completamente explicados. En un mode-lo experimental de fibroblastos peritone...

Unlabelled: Sclerosing encapsulating peritonitis secondary to peritoneal dialysis has been associated to acetate-containing dialysis fluids, hypertonic glucose and disinfectants. Physiopathologic mechanisms of fibrotic proliferation that implicate those agents are not totally explained. With an experimental approach using cultured peritoneal fibro...

In this article, I focus on recent advances in our knowledge, at the molecular level, about extracellular and intracellular interactions mediated by specific classes of molecules and the specific signals and sequence motifs involved. This could be the foundation for future attempts at engineering specific structural/functional domains into therapeu...
