Abstract: youth soccer is becoming increasingly professionalized to the point of being admitted to adult teams playing in the top leagues. for this to happen it is necessary that young athletes are physically fit to meet the physical demands of professional soccer. anthropometric assessment was performed in a total of 217 subjects divided into two groups, sub 16 and sub 17. the young players have differences in body structure with respect to professional players, showing a lack of sports development and maturation, which the evidence, the less physically fit to face the physical demands are typical of professional soccer. the muscle mass of subjects is less than professional players, so they are not suitable for inclusion in the professional team in competition matches, with the risk of injury and having a lower physical performance.

Abstract: El fútbol juvenil, se profesionaliza cada día más, al punto de incluir a los jóvenes en los equipos adultos que juegan en los Torneos Profesionales. Para que esto ocurra es necesario que los jóvenes deportistas estén físicamente aptos para enfrentar las exigencias físicas del futbol profesional. Se evaluó antropométricamente a un total de 217 sujetos distribuidos en dos grupos, sub 16 y sub 17. Los jóvenes futbolistas, presentan diferencias en la estructura corporal con respecto a futbolistas profesionales, demostrando una falta de desarrollo madurativo y deportivo, que según la evidencia, los hace menos aptos físicamente, para enfrentar exigencias físicas, típicas del futbol profesional. La masa muscular de los sujetos es menor que la de futbolistas profesionales, por lo que no están aptos para ser incluidos dentro del equipo de honor en los partidos de competencia, con el riesgo de sufrir lesiones y de tener un rendimiento físico menor.

The parietal association cortex of the rat
TORREALBA,FERNANDO; VALDéS,JOSé LUIS;
Biological Research , 2008, DOI: 10.4067/S0716-97602008000400002
Abstract: spatial cognition is a complex higher function in mammals and is involved in a variety of tasks that can be explored in the laboratory. in this review we will discuss the role of the posterior parietal/anteromedial cortex of rodents, also known as the parietal association cortex, and the hippocampal formation in spatial navigation. we will also discuss other higher associational functions of the posterior parietal/anteromedial cortex as they relate to dr. pinto-hamuy's contribution to understanding behavioral functions.

La corteza prefrontal medial controla el alerta conductual y vegetativo: Implicancias en desórdenes de la conducta
Valdés G,José Luis; Torrealba L,Fernando;
Revista chilena de neuro-psiquiatría , 2006, DOI: 10.4067/S0717-92272006000300005
Abstract: the frontal lobe, the most human part of the brain (goldberg), has been intensely studied, particularly in the last decades. this region is crucial for the control of behavior, cognition, planning, and working memory. both behavior and higher cognitive abilities depend importantly on the arousal level, and on the autonomic responses that anticipate and accompany behaviors. in this review we will discuss the role played by the medial prefrontal cortex in controlling the level of vigilance and the autonomic and endocrine responses that are crucial for normal behavior. we will also discuss how dysfunctions of the medial prefrontal cortex resulting in the loss of the cortical control over arousal (both behavioral and vegetative) can help to explain the behavioral alterations observed in patients with posttraumatic stress, schizophrenia, attentional deficit and hyperactivity disorder and antisocial and aggressive behavior. additionally we will discuss how studies in rats may give us valuable information about of the mechanisms by which the medial prefrontal cortex is capable of controlling the arousal state, autonomic and emotional responses in humans
La corteza prefrontal medial controla el alerta conductual y vegetativo: Implicancias en desórdenes de la conducta The medial prefrontal cortex controls the behavioral and vegetative arousal: Implications for behavioral disorders

Revista Chilena de Neuro-Psiquiatría , 2006,
Abstract: El lóbulo frontal, la parte más humana del cerebro, como lo propone E. Goldberg, ha llamado intensamente la atención de los investigadores en las últimas décadas. Esta región es clave en el control de la conducta, la personalidad, la memoria de trabajo, y en funciones cognitivas superiores. Sin embargo, tanto la conducta como las habilidades cognitivas superiores dependen de manera importante del estado de alerta, y de las respuestas autonómicas y emocionales asociadas. En esta revisión discutiremos acerca del papel que la corteza prefrontal medial juega en el control del alerta, y cómo alteraciones en la actividad de la corteza prefrontal medial, al afectar dicho control cortical, pueden explicar las alteraciones conductuales observadas en pacientes con estrés postraumático, esquizofrenia, déficit atencional y conductas antisociales y agresivas. Adicionalmente discutiremos cómo los estudios en la rata pueden darnos valiosa información sobre los mecanismos por los cuales la corteza prefrontal medial es capaz de manejar el alerta, el control autonómico y el control emocional The frontal lobe, the most human part of the brain (Goldberg), has been intensely studied, particularly in the last decades.

Histamine and motivation
Fernando Torrealba,Maria E. Riveros,Jose L. Valdes
Frontiers in Systems Neuroscience , 2012, DOI: 10.3389/fnsys.2012.00051
Abstract: Brain histamine may affect a variety of different behavioral and physiological functions; however, its role in promoting wakefulness has overshadowed its other important functions. Here, we review evidence indicating that brain histamine plays a central role in motivation and emphasize its differential involvement in the appetitive and consummatory phases of motivated behaviors. We discuss the inputs that control histaminergic neurons of the tuberomamillary nucleus (TMN) of the hypothalamus, which determine the distinct role of these neurons in appetitive behavior, sleep/wake cycles, and food anticipatory responses. Moreover, we review evidence supporting the dysfunction of histaminergic neurons and the cortical input of histamine in regulating specific forms of decreased motivation (apathy). In addition, we discuss the relationship between the histamine system and drug addiction in the context of motivation.

Abstract: rhinophyma is a progressively growing benign tumor that has the ability to distort the nasal form. even though, it is considered a rare subtype of rosacea, it is of great importance for the ability to create: psychic, aesthetic and functional disorders. this report describes a severe case of rhinophyma in a 52 years old male patient, the medical treatment and the surgical technique used for removal.
