Marca de joyas inspirada en la Cultura "Tolita" reinterpretación del diseño ancestral
Diseño de joyas de plata con las formas de la cultura Tolita. El diseño de joyas puede ser una manera de recuperar los símbolos de una cultura ancestral.
Tema: Diseño de joyas de plata en base a la reinterpretación de las formas de la joyería de la cultura Tolita. El diseño corporal y las joyas forman parte de la expresión de la identidad cultural de los pueblos, en ellos se encuentran los símbolos que contienen una información sobre la cosmovisión de sus pobladores, recuperar estos símbolos es actualizar su significado. La suma de experiencia y saberes colectivamente acumulados a lo largo del tiempo y la creatividad hacen posible la expresión artística artesanal de la joyería, en donde se expresa la cultura del pueblo Tolita. Esta expresión es antropomorfa y zoomorfa en formas geométricas predominan rasgos de animales tales como el jaguar, el mono, varios tipos de aves, y reptiles de una manera estilizada con detalles en alto relieve, con piezas móviles y uso de piedras preciosas. En cuanto al aspecto antropomorfo, la presencia de máscaras, detalles de nariz, ojos y boca. Los antiguos pobladores, de lo que hoy es el Ecuador constituyen la base de la nacionalidad ecuatoriana. El Ecuador se asienta sobre un territorio en la costa, sierra, oriente, y peninsular. La cultura se asienta en la costa ecuatoriana en lo que hoy es actualmente la provincia de Esmeraldas y parte de Manabí
Abordagem do diagnóstico e tratamento do síncope durante a gravidez. : Revisão de três casos
Introduction: Syncope is a symptom consisting of a brief loss of consciousness, which occurs because of a self-limiting, relatively transitory, and spontaneous period of inadequate supply of irrigation in the brain. The possible causes are numerous. Syncope and presyncope are prevalent in pregnancy, however, the etiology during pregnancy are not well defined.
Series of Cases: In this series of cases, three patients with syncope are presented. The first patient presented syncope during pregnancy; the second one was known because of neurogenic syncope before pregnancy and presents an increase in the frequency of episodes. And the third one presented syncope at the beginning of gestation.
Conclusion: It is relevant to establish a diagnostic and monitoring protocol to define the cause of syncope during pregnancy. In order to establish if there is a cardiac alteration that could complicate the mother or the fetus in the course of the gestation, at the delivery time or at the puerperium, and not only consider it to be an isolated event related to hemodynamic changes or physiological effects of the own pregnancy. Finally, specifying the cause of the syncope in pregnancy, a better follow-up is obtained during the prenatal control and programming the moment of delivery according to established protocols, and thus, preventing complications to the "mother-child binomial".
Key words: Syncope, pregnancy, prevention, vasovagal syncope.Introducción: El síncope es un síntoma que consiste en la pérdida transitoria de la conciencia, que ocurre como consecuencia de un período autolimitado, relativamente breve, y espontáneo de un suministro inadecuado en la irrigación cerebral. Las posibles causas son numerosas. El síncope y el presíncope son prevalentes en el embarazo, sin embargo, en muchas ocasiones la etiología durante el embarazo no está del todo bien definida.
Serie de casos clínicos: En esta serie de casos, se presentan a tres pacientes con síncope. La primera paciente presentó un síncope durante el embarazo; la segunda presentó síncope neurogénico previo a la gestación, y cursa con aumento en la frecuencia de episodios. En el caso de la tercera paciente presentó un síncope en las primeras semanas de embarazo.
Conclusión: Es de vital importancia establecer un protocolo diagnóstico y de seguimiento para definir la causa del síncope durante el embarazo. Establecer si hay alteración cardiaca de base que pudiera complicar a la madre o al feto en el transcurso de la gestación, en el parto o en el puerperio, y no solamente considerarlo un evento aislado relacionado con cambios hemodinámicos o efectos fisiológicos del propio embarazo, sino que al precisar la causa del síncope en el embarazo se obtiene un mejor seguimiento en el control prenatal, una programación del momento del desembarazo oportuno y protocolariamente, previniendo así, complicaciones al “binomio madre-hijo”.
Palabras clave: Síncope, embarazo, prevención, bloqueo auriculoventricular, bloqueo de ramaIntrodução. A síncope é um sintoma que consiste na perda transitória da consciência em consequência do fornecimento inadequado na irrigação cerebral. É autolimitada, relativamente breve, espontânea, as causas são numerosas e tanto a síncope quanto a pré-síncope são prevalentes na gravidez. No entanto, a etiologia não está totalmente bem definida. O objetivo desta revisão é determinar a importância da identificação oportuna das causas da síncope na gravidez e seu tratamento adequado para evitar resultados materno-perinatais adversos.
Série de casos clínicos. A análise se faz a partir do estudo em retrospectiva dos prontuários de três pacientes com síncope. A primeira paciente apresentou síncope cardiogênica durante a gravidez; a segunda apresentou síncope neurogênica prévia à gestação com aumento da frequência dos episódios durante a gestação e a terceira paciente apresentou síncope cardiogênica nas primeiras semanas de gestação. Conclusão. É de vital importância estabelecer um protocolo de diagnóstico e acompanhamento para definir a causa da síncope durante a gravidez e determinar se há uma anormalidade cardíaca subjacente que possa complicar a mãe ou o feto durante a gravidez, parto ou puerpério. Também deve ser considerado como um evento não isolado, relacionado a alterações hemodinâmicas ou efeitos fisiológicos da gravidez, e a causa, nesta fase, deve ser especificada para melhor acompanhamento no controle prénatal e agendamento do tempo de alta em tempo hábil para evitar complicações
On the microscopic mechanism behind the purely orientational disorder-disorder transition in the plastic phase of 1-chloroadamantane
Globular molecules of 1-chloroadamantane form a plastic phase in which the molecules rotate in a restrained way, but with their centers of mass forming a crystalline ordered lattice. Plastic phases can be regarded as test cases for the study of disordered phases since, contrary to what happens in the liquid phase, there is a lack of stochastic translational degrees of freedom. When the temperature is increased, a hump in the specific heat curve is observed indicating a change in the energetic footprint of the dynamics of the molecules. This change takes place without a change in the symmetry of the crystalline lattice, i.e. no first-order transition is observed between temperatures below and above the calorimetric hump. This implies that subtle changes in the dynamics of the disordered plastic phase concerning purely orientational degrees of freedom should appear at the thermodynamic anomaly. Accordingly, we describe, for the first time, the microscopic mechanisms behind a disorder–disorder transition through the analysis of neutron diffraction and QENS experiments. The results evince a change in the molecular rotational dynamics accompanied by a continuous change in density.Peer ReviewedPreprin

Relationship of Body Composition with the Strength and Functional Capacity of People over 70 Years
Producción CientíficaBackground: Aging is a multifactorial physiological phenomenon, in which a series of changes in the body composition occur, such as a decrease in muscle mass and bone mineral density and an increase in fat mass. This study aimed to determine the relationship of muscle mass, osteoporosis, and obesity with the strength and functional capacity of non-dependent people over 70 years of age. Methods: A cross-sectional study was designed, whose study population was all people aged over 70 years, living independently and attending academic and recreational programs. Muscle strength and functional capacity of the participants were assessed by isometric exercises of lower and upper limbs and by four tests taken from the Senior Fitness Test, respectively. Bone mineral density, total mass, fat mass, total lean mass, arms lean mass, legs lean mass, and appendicular lean mass (ALM) was calculated by dual energy X-ray absorptiometry. Differences in muscle strength and functional capacity, according to the sex, muscle mass, mineral bone density and fat mass, were measured by χ2 test, independent samples Student’s t-test, analysis of covariance and a 2-factor analysis of covariance; Results: 143 subjects were included in the study group. Men and women with an adequate amount of ALM adjusted for body mass index (BMI) had a maximal dynamic biceps strength in a single repetition, a maximal isometric leg extension strength, a maximal dynamic leg extension strength in a single repetition, a maximum right hand grip strength and maximum hand grip strength (the highest). Significantly higher values were observed in the maximal isometric biceps’ strength in men with osteoporosis. Obese men had less isometric strength in the biceps and took longer to perform the chair stand test; Conclusions: Men and women with an adequate amount of ALM adjusted for BMI obtained better results in tests of muscle strength and functional capacity. However, osteoporosis and obesity are not related to these parameters

Influence of a Physical Exercise Program in the Anxiety and Depression in Children with Obesity
[EN] Background: The high prevalence of childhood obesity and its multicausal etiology make it necessary to approach it through different strategies, whose objective is to promote the physical, mental, and social well-being of children. Regular physical activity, in addition to having positive effects on the physical environment of those who practice it, influences positively in psychological aspects such as anxiety and depression, which are very frequent in children with obesity and overweight. (2) Objective: To analyze the changes produced by a program of physical exercise based on anthropometric indicators and levels of anxiety and depression in a population of Mexican children with obesity. (3) Methods: A longitudinal study with experimental group (EG) and control group (CG). The analysis population consisted of 105 children with a body mass index (BMI) for their gender and age group above the 95th percentile, of which 60 were girls and 45 were boys, with a mean age of 10.02 years (SD ± 0.79). By randomizing the participants, 54 were part of the EG and 51 of the, CG The EG participated in a physical exercise program, distributed in two weekly sessions, each lasting 50 minutes, for 20 consecutive weeks. The CG group continued its usual activities during the intervention period. An inferential analysis was performed between the socio-demographic, anthropometric and psychological variables. (4) Results: The implementation of a physical exercise program in children with obesity favors the appearance of positive thoughts, with improvements in their emotional well-being, self-perception and self-concept; although it does not produce significant changes in weight, height, Z-Score, level of anxiety or depressive thoughts. (5) Discussion: Regular physical exercise practice has positive effects on mental health, although new studies are required to analyze specifically its influence on anxiety and depression in children with obesity.S
