El objetivo de este estudio fue analizar el valor de mercado (VM) de futbolistas profesionales de las 5 mejores ligas europeas de fútbol. Se analizó el efecto de las variables independientes sobre el VM de los futbolistas, mediante una ANOVA con un nivel de significación de p <0.01. Los futbolistas de la Premier League (PL) mostraron mayor VM en co...
The aim of this study was to compare the external loads (i.e., displacement distances and velocities) of 10–11 years-old soccer players during Soccer-7 (i.e., seven-a-side), Soccer-8 (i.e., eight-a-side), and Soccer-11 (i.e., eleven-a-side) official matches.

Interleukin-1 beta (IL-1β) is a cytokine linking the neuroendocrine system and metabolic homeostasis. We have previously demonstrated the relevance of IL-1β for maintaining the pituitary ACTH-producing cells by immuno-blocking its effects in pituitary cultures. However, the morphological characteristics and the intimate relationship of the pituitar...
The pituitary gland is part of hypothalamic-pituitary–gonadal axis, which controls development, reproduction, and aging in humans and animals. In addition, the pituitary gland is regulated mainly by hormones and neurotransmitters released from the hypothalamus and by systemic hormones secreted by target glands. Aromatase P450, the enzyme responsibl...
To compare the effects of high intensity interval training (HIT) with one versus three changes of direction (COD) on youth (age, 17.21.1 y) female basketball players’ performance, 6-wk of regular basketball training (control period) was followed by random allocation of athletes to either HIT with one (HIT-COD1; n=6) or three COD (HIT-COD3; n=6), t...

Changes in the morphology and number of prolactin-immunoreactive cells have been described in hypothyroidism. However, no analyses of the changes that occur in the proliferation of these cells have been undertaken. In order to determine the proliferation rate of rat hypophyseal prolactin cells in hypothyroidism and whether the observed changes are...
Glucocorticoids are the physiological negative feedback on ACTH secretion and may be involved in regulating the maintenance of the population of hypophyseal ACTH-cells, because following surgical ablation, adrenalectomy induces an increase in the number of these cells in the early stages. Glucocorticoids have been implicated in the induction of apo...
Aromatase P450, the enzyme responsible for the catabolism of aromatizable androgens to estrogens is involved in sexual dimorphism and several pathologies induced by estrogenic effects. The present work reports evidence of pituitary aromatase synthesis, its regulation by gonadal steroids, and the physiological roles of aromatase on pituitary endocri...
In previous studies we demonstrated the immunohistochemical expression of aromatase in pituitary cells. In order to determine whether pituitary aromatase is involved in the paracrine regulation of prolactin-producing pituitary cells and the physiological relevance of pituitary aromatase in the control of these cells, an in vivo and in vitro immunoc...

Interleukins are proteins involved in the immune system and have been related to the endocrine regulation of the hypothalamic-pituitary-adrenal axis as well as to the secretion of ACTH, prolactin (PRL), GH and, possibly, LH. Like interleukin-6 (IL-6), vasoactive intestinal peptide (VIP) is synthesized in the pituitary gland and stimulates prolactin...

Interleukin 1b (IL-1b) stimulates the hypothalamic- pituitary-adrenal axis, however the autoparacrine effects of IL-1b¿ on pituitary ACTHproducing cells and the relations among IL-1b and Arg-vasopressin or corticosterone have not yet been analyzed. To address these effects, pituitary monolayer cultures were treated with IL-1b, Arg-vasopressin and c...
