Abstract

The pineal gland is an endocrine gland, which is responsible for the human circadian rhythm, through the regulation of its hormone – melatonin. The most common pathology of a pineal gland is pineal cyst – its population incidence is estimated as 1-23%, depending on the publication. The most common symptoms of a pineal cyst include headache (87%), visual field defects (54%), nausea/vomiting (34%), and dizziness/vertigo (31%). Among the majority of patients with the asymptomatic pineal cyst, the wait-and-see strategy is proper. According to the newest meta-analyze, the prevalence of sleep disturbances among patients with pineal cyst estimates to be 17%. The results of direct melatonin level measurements in pineal cysts remain unclear. The study focused on sleep disturbances in pediatric patients with pineal cysts and showed a significantly higher score on Sleep Disturbance Scale for Children (SDSC) in the domains of disorders of excessive sleepiness and disorders of initiating and maintaining sleep than the control groups. The impact of lesion on sleep quality correlated with its size. The pineal cyst may be considered a rare, and potentially reversible, cause of sleep disorders. Nevertheless, according to the present reports (often opposite to each other), this thesis and the mechanism of its occurrence need to be further researched.

Abstract

What is charisma? What is that attracts viewer’s attention? What characterizes the capacity to act? These questions challenged many people. Following the suggestion made by those questions, we provided a series of experiments aimed to prove the existence of a Presence Energy that, by means of training and rehearsal, is able to change the proprioception of the trained person and his power of observation. It is not a coincidence that many authors and researchers tried to deepen the connection with mysticism and faith. This Presence Energy’s existence interested lots of aspect above the theatrical one: it could become a path for charisma and awareness.

Abstract

In order to discuss and analyze the available information concerning the seasonal breeding behavior of sheep in Mexico, this review was conducted. We analyzed the neuroendocrine basis that modulate the annual reproductive cycle in sheep and then discussed the degree of reproductive seasonality in Creole sheep wool, breeds originating in high latitudes and hair sheep, mainly in Pelibuey ewes. The Creole sheep wool show continuous annual reproductive activity and short seasonal anestrous. The females of northern origin, express seasonal reproductive activity, similar to that observed in individuals geographically located at latitudes above 35º. Pelibuey sheep show variable annual reproductive behavior with reduced anestrus or lack thereof.  It is suggested that the neuroendocrine mechanisms regulating seasonal anestrus in ewes, are active in the sheep of northern origin that live in Mexico, in a manner contrary is not activated in Creole and hair sheep.

Abstract

Treball Final de Grau en Medicina. Codi: MD1158. Curs acadèmic: 2017/2018 Our object of study are maternal behavio u rs , defined as every conduct aimed at increasing the survival of the offspring. These behaviours also contribute to the proper physical and psychological development of the infants , whereas their e alterations produce serious disorders that could threaten the life of the offspring. Our working hypothesis is that the socio - sexual brain ( neural circuit regulating social behaviours), undergoes profound functional changes during motherhood, becom ing especially sensitive to the offspring and promoting maternal behaviours . To test this, we have exposed mouse females (mothers and virgins) to different stimuli (pups and buttons), and we have quantified the derived neuronal activity by means of the immunohistochemical detection of the c - Fos prot e in in chosen nuclei of the socio - sexual brain . Our study did not find significant differences in the neuronal activation of the studied nuclei , although the re was a tendency in one of them ( ventromedial hypothalamus ) . We also f ou nd correlation s between the activ ation of some of the analyzed socio - sexual center s in mothers ( posterodorsal amígdala , medial preoptic nucleus and lateral septum ) , indicating that these are activated in a coordinated fashion. These data suggest functional changes in the brain related to motherhood. Nuestra hipótesis de trabajo es que el cerebro socio - sexual ( circuito neural que regula las conductas sociales ) experimenta cambios funcionales profundos dura nte la maternidad, volvi éndose especialmente sensibles a las crías y facilitando la conducta maternal . Para comprobar esto, hemos expuesto a hembras de ratón (madres y vírgenes) a estímul os distintos (crías y botones), y hemos cuantificado la actividad neuronal derivada mediante la detección inmunohistoquímica de la proteína c - Fos en centros escogidos del cerebro socio - sexual . Nuestro estudio no ha encontrado diferencias significativas en la actividad neuronal de los núcleos estudiados, aunque sí una tendencia en uno de ellos (hipot álamo ventromedial) También hemos encontrado correlaci o n es entre la a ctivación neuronal de varios centros del cerebro socio - sexual de madres ( am ígdala posterodorsal , área pre óptica medial y septum lateral) indicando que éstos se activan de forma coordinada. Estos datos sug ieren cambios funcionales en el cerebro relacionados con la maternidad.

Abstract

La violencia contra las mujeres se manifiesta especialmente en el ámbito familiar. El patrón de conducta en los entornos familiares tiene un componente biológico que se sustenta en un conjunto de controles neuroendocrinos objeto de estudio de la Fisiología. La presencia de ciertas hormonas se asocia al desarrollo de conductas resistentes al estrés o vulnerables ante el daño. La primera condición haría a la persona resiliente; la segunda le impediría tomar las decisiones adecuadas para salir de la situación de peligro. El hecho de que las conductas defensivas (que pasan por denuncias o búsquedas de apoyo en la red social) en las mujeres víctimas de violencia de género estén mermadas, puede que sea debido, entre otros factores, a que el daño continuado ha afectado también a su control neuroendocrino. El objetivo del presente proyecto de investigación se ha centrado en evaluar los niveles de ciertas hormonas tradicionalmente relacionadas con la gestión de los niveles de estrés agudo (cortisol y prolactina) y del establecimiento de relaciones grupales y de apego (oxitocina) y relacionarlo con los niveles de recuperación de las víctimas. El estudio de las bases fisiológicas de la resiliencia puede conducir a implementar herramientas que permitan evaluar objetivamente el nivel de exposición al maltrato y actuar en consecuencia, mejorando la capacidad de recuperación de la víctima. The violence against women singularly occurs in the familiar environment. The behavioral pattern within the familiar nucleus has a biological basis that it is under the neuroendocrine control. The blood concentrations of certain hormones are associated to the stress resistance or to the vulnerability under stress damage. The first condition facilitates the individual resilience, whether the second condition impedes the individuals to take the appropriate decisions to get out of the dangerous situation. The defensive behavior that the violence women victims should use (police reports or looking for social support) are diminished; this fact could probably be due to the effects of continuous violence over the women has done on their neuroendocrine control. The aim of the present research project has been to evaluate the blood levels of certain hormones, related to acute stress (cortisol and prolactin) and those related with the establishment of social links and attachment (oxytocin), and to relate those levels with the recuperation levels of the woman victims. The knowledge of the physiological basis of their basic mechanisms of resilience could imply a better management of the violence exposition of the victims and their consequences, trying to implement a better recuperation of the victims.

Abstract

Introduction: Throughout history, the special anatomical location of the pineal gland in the central nervous system has given rise to a number of physiological hypotheses regarding the functional role of this organ., Development: In classical ancient times, the pineal body (conarium) was considered to be a sort of valve-like sphincter that regulated the flow of the spiritus animalis at the ventricular level. But it was not until the 17th century that the pineal gland finally reached its highest levels of physiological significance, when Rene Descartes considered it to be the anatomical structure that housed the seat of the soul., Conclusions: The Cartesian hypotheses regarding the pineal gland did not arouse much interest in the scientific community of the time, and attention to this organ dwindled from then until the 20th century, when its neuroendocrinological nature was finally confirmed.

Abstract

The incorporation of subjective elements provided by the patient to medical practice constitutes a new bridge between two historical movements of human culture: naturalism and rationalism. In recent years, medical sciences have identified these movements as patient-centered medicine and evidence-based medicine. By revisiting the paradigms of medicine, theories of causality, doctor-patient relationship models, bioethical principles and examples of clinical studies, their role and meaning has been revised. The applicability for neuroendocrinology has been demonstrated by validating therapeutic results with measurement of health-related quality of life. The need to incorporate the patient's subjective perception poses a challenge that, when accepted, can advance the understanding and care of human beings--ultimately rational, thinking subjects, and therefore subjective--as our species has been defined.
