Efectos de la Terapia Acuática Específica Halliwick en Niños con Trastorno del Espectro Autista con Retraso Psicomotor.
Introducción: Este estudio de investigación tuvo como objetivo analizar los efectos de la Terapia Acuática Específica Halliwick, en las habilidades motoras gruesas en niños con TEA con retraso psicomotor.
Métodos: La intervención con el método Halliwick WST se realizó en ocho semanas con un grupo de niños y niñas con TEA con retraso psicomotor, 8 participantes entre 4 a 11 años. El grado de retraso psicomotor se evaluó con la prueba de desarrollo de motricidad gruesa TGMD-2 de Ulrich con tomas previas y final.
Resultados: En la prueba de desarrollo de motricidad gruesa TGMD-2 se observó una diferencia significativa (p < 0.05) entre la toma final respecto a la inicial en la prueba de Wilcoxon Z= -2.032; p=.04, efecto mayor en la toma final respecto a la inicial, con importantes mejoras en las habilidades motrices. El cálculo de la potencia muestral arroja 1-ß = .85. La prueba del tamaño del efecto de Cohen resultante, d= 1.20 “muy grande” comparando toma final con la inicial. Se acepta la hipótesis con datos de fiabilidad y significancia clínica, pero sin garantía de relevancia estadística por el tamaño muestral pequeño.
Conclusiones: El método Terapia Acuática Específica Halliwick mostró resultados positivos en el desarrollo en las habilidades motoras gruesas en niños con TEA con retraso psicomotor
Convivencia
Poema: Convivencia.
Se refiere a la busqueda infructuosa de una de las tantas victimas y que asesinadas o desaparecidas, sus seres queridos ointentan encontrarlos en el desierto, en el cual, la luna es testigo de su triste caminar y del esfuerzo a traves de años y mientras simbolicamente ellos expresan su tragedia en un lugar cualquiera como un recuerdo a sus perdidas en el año nuevo; la complicidad entre los sicarios y el poder judicial celebran la vida con viandas cinicamente frente a sus familias
La cascada de Basaseachi
En mis tiempos de la infancia, transcurridos en el pueblo de Pascual Orozco, la cascada de Basaseachi era una especie de leyenda. No eran muchos los que la habían visitado, aunque algunos arrieros sobrevivientes de un oficio milenario, en el cual se habían ocupado casi todos los ancestros del pueblo, platicaban de ella con entusiasmo. Y no se conocía porque la única forma de llegar era a lomo de mula en fatigosas jornadas. Sin embargo, las recuas antaño omnipresentes y que apenas alcancé a conocer, casi habían desaparecido. Viajantes y mercancías se desplazaban en el ferrocarril y en camiones o unos pocos en automóviles de pasajeros
El Paso, Texas: Un modelo de éxito en la recepción de migrantes y solicitantes de asilo en los Estados Unidos
La “crisis migratoria” en la frontera entre Estados Unidos y México ha sido objeto de mucha atención política e intenso escrutinio mediático. La retórica incendiaria de algunos políticos ha dominado las noticias y los titulares sobre miles y miles de migrantes y solicitantes de asilo que intentan cruzar la frontera han generado una percepción de caos y descontrol. Sin embargo, a menudo se pasan por alto las historias de éxito, como la manera en la que El Paso, Texas, gestiona la recepción de migrantes y solicitantes de asilo. Esta ciudad fronteriza se ha convertido en un caso ejemplar de la gestión de la migración y ha desarrollado un sistema de recepción eficiente y humano que puede servir de modelo para otras ciudades fronterizas. Este ensayo examina las estrategias y prácticas aplicadas en El Paso para ilustrar cómo esta ciudad ha logrado gestionar de manera efectiva la recepción de migrantes y solicitantes de asilo a través de la adaptación y mejora continua de sus prácticas
Comportamiento nocturno del Gallus gallus domesticus
The knowledge of the sleeping behaviour of hens is important to contribute to suggestions
on the welfare of these productive birds in commercial farms that are of great importance in
the contribution of protein of animal origin. The aims were to investigate the nocturnal
behaviour of a group of domestic birds of the genus Gallus gallus to find out the proportion
of time spent by the birds in the different nocturnal sub-states. The nocturnal behaviour was
observed during three consecutive days during the month of September of a group of seven
birds, two roosters and five hens, 20 weeks old, for which a nocturnal behaviour certificate
was used starting from sunset to sunrise. The data obtained are presented in proportion of
time. The largest proportion of nighttime (77%) was spent sleeping, followed by grooming
(8%), and with the same proportion sleeping standing up and lying awake (4%). It is
concluded that the data obtained from the group of birds show a higher proportion of prostrate
and standing sleep, followed by grooming, from sunset until before sunrise the next day
Framework for heterogeneous data management: An application case in a NoSQL environment from a Climatological Center
Processing, visualizing and understanding data from meteorological networks can present several challenges due to the variety and complexity of the data and must be accessible in real time and in different formats, protocols and standards. This paper presents the development of an innovative technological framework for handling heterogeneous climatological data in a NoSQL environment. The framework was developed following the Action Research methodology and enables the extraction of heterogeneous data, their homogenization, and the creation of a dataset. Its real-case application took place in data repositories used for climatological data management in a specialized regional center in Ciudad Juarez, Mexico. The ´ main repository use MongoDB and contain 631,202 documents with data from several meteorological stations. A 70% reduction in data processing time is evidence that the methodology and framework developed were effective in the case of the application. In addition, the generated data sets are homogenized and in formats compatible with advanced analysis tools
Vomeronasal organ volume increases with body size and is dissociated with the loss of a visual signal in Sceloporus lizards
Many organisms communicate using signals in different sensory modalities (multicomponent or multimodal). When one signal or component is lost over evolutionary time, it may be indicative of changes in other characteristics of the signalling system, including the sensory organs used to perceive and process signals. Sceloporus lizards predominantly use chemical and visual signals to communicate, yet some species have lost the ancestral ventral colour patch used in male–male agonistic interactions and exhibit increased chemosensory behaviour. Here, we asked whether evolutionary loss of this sexual signal is associated with larger vomeronasal organ (VNO) volumes (an organ that detects chemical scents) compared with species that have retained the colour patch. We measured VNO coronal section areas of 7–8 adult males from each of 11 Sceloporus species (4 that lost and 7 that retained the colour patch), estimated sensory and total epithelium volume, and compared volumes using phylogenetic analysis of covariance, controlling for body size. Contrary to expectations, we found that species retaining the ventral patch had similar relative VNO volumes as did species that had lost the ancestral patch, and that body size explains VNO epithelium volume. Visual signal loss may be sufficiently compensated for by increased chemosensory behaviour, and the allometric pattern may indicate sensory system trade-offs for large-bodied species
Bioprospection of rattlesnake venom peptide fractions with anti-adipose and anti-insulin resistance activity in vitro
Animal venoms are natural products that have served as a source of novel molecules that have inspired novel drugs for several diseases, including for metabolic diseases such as type-2 diabetes and obesity. From venoms, toxins such as exendin-4 (Heloderma suspectum) and crotamine (Crotalus durissus terrificus) have demonstrated their potential as treatments for obesity. Moreover, other toxins such as Phospholipases A2 and Disintegrins have shown their potential to modulate insulin secretion in vitro. This suggests an unexplored diversity of venom peptides with a potential anti-obesogenic in Mexican rattlesnake venoms. For that reason, this study explored the in vitro effect of Crotalus venom peptide-rich fractions on models for insulin resistance, adipocyte lipid accumulation, antioxidant activity, and inflammation process through nitric oxide production inhibition. Our results demonstrated that the peptide-rich fractions of C. aquilus, C. ravus, and C. scutulatus scutulatus were capable of reverting insulin resistance, enhancing glucose consumption to normal control; C. culminatus, C. molossus oaxacus, and C. polystictus diminished the lipid accumulation on adipocytes by 20%; C. aquilus, C. ravus, and C. s. salvini had the most significant cellular antioxidant activity, having nearly 80% of ROS inhibition. C. aquilus, C. pyrrhus, and C. s. salvini inhibited nitric oxide production by about 85%. We demonstrated the potential of these peptides from Crotalus venoms to develop novel drugs to treat type-2 diabetes and obesity. Moreover, we described for the first time that Crotalus venom peptide fractions have antioxidant and inflammatory properties in vitro models
