Mejora de formulación de un producto en polvo vegano para niños de 1 a 3 años

Se modificó la formulación del PAP realizada en primavera 2022 variando las cantidades de los componentes que conforman la formulación para así poder cumplir con la normativa de grasa mínima en fórmulas de continuación mencionada en la NOM-131, la cual indica un rango de 3.00 a 6.00 g grasa/100 kcal ya que la formulación hecha en el PAP antes mencionado contenía una cantidad de 2.72 g grasa/100 kcal. Se buscaba llevar la formulación a un mínimo de 3.00 g grasa/100 kcal sin comprometer las propiedades sensoriales de dicha formulación por lo que se optó reformular dos veces, logrando una cantidad de grasa teórica contenida de 3.00 y 3.06 g grasa/100 kcal en las reformulaciones 1 y 2 respectivamente, al momento de comprobar estas cantidades experimentalmente mediante el método de Goldfish se encontraron valores de 2.66 y 3.26 g grasa/100 kcal correspondientes a las reformulaciones 1 y 2. Posteriormente se realizaron pruebas sensoriales para determinar condiciones de sabor, olor y textura obteniendo así mejores resultados a las pruebas la reformulación 2, sin embargo, gracias a la comparación de resultados sensoriales con la formulación inicial del PAP primavera 2022 la organización decidió trabajar con dicha fórmula la cual fue escalada a la capacidad productiva de la planta con una carga de 264 kg en su mezcladora de listón aprovechando al máximo los costales requeridos de harina de soya, petición hecha por la organización.ITESO, A.C

Academic motivation in physical education teacher education

La regulación integrada se ha mostrado como la regulación motivacional con mayor poder predictivo sobre las conductas adaptativas en diferentes ámbitos de la vida, sin embargo, aún no ha sido estudiada en el contexto educativo. El objetivo de este estudio fue incorporar la medida de la regulación integrada a la Escala de Motivación Educativa y observar las propiedades psicométricas de este instrumento. Participaron en el estudio 333 universitarios del área de Educación Física de la Universidad Federal do Espirito Santo/ Brasil. El análisis factorial confirmatorio mostró índices de ajuste aceptables para el modelo de ocho factores correlacionados. Los resultados del análisis de regresión mostraron que la regulación integrada fue la variable que mejor predijo la intención de ser profesor. Este instrumento podría contribuir a una mayor comprensión de los procesos motivacionales involucrados en el ámbito de la formación inicial en Educación Física en BrasilIntegrated regulation has been showed as the motivational regulation with the highest predictive power on adaptive behaviours in different life domains; however, it has not been examined in the educational context yet. The purpose of this study was to incorporate the assessment of integrated regulation to the Academic Motivation Scale in the initial training of Physical Education teachers in Brazil and examine the psychometric properties of this instrument. There were 333 undergraduate participants from the bachelor degree of Physical Education, Federal University of Espirito Santo/ Brazil. Confirmatory factor analysis showed acceptable fit indices for the eight-factor correlated structure. The results of the regression analysis showed that the variable integrated regulation was the strongest predictor of the intention to become a teacher. This new instrument may contribute to a deeper understanding of the motivational processes involved in the initial training of Physical Education teacherEsta investigación ha sido realizada gracias a la ayuda recibida por parte de la Fundación Carolin

Palatability of Alfalfa (\u3cem\u3eMedicago sativa\u3c/em\u3e L.) and Orchard Grass (\u3cem\u3eDactylis glomerata\u3c/em\u3e L.) Silages

The objective was to compare palatability with different methodologies for characterizing silages at Chapingo Autonomous University, México. Eight silages were used resulting from an experiment which evaluated effects of cutting time (08:00 and 14:00), time of wilting (0, 1 and 2 h) and use of lactic bacteria inoculant on properties of alfalfa (Medicago sativa L.) and orchard grass (Dactylis glomerata L.) silages. Organoleptic properties (odor, color, texture, moisture) were assessed by trained observers, using as categories: excellent, good, fair and poor. Dry matter content, CO2 rate of production and pH were also measured. For the evaluation of palatability with ewes, the experiment encompassed 18 days of adaptation and 14 days of measurement. In each of the 14 days of evaluation, four combinations of silages were evaluated (three silages per combination), each one assigned to experimental units formed by three ewes allotted by means of ratified random; each experimental unit was housed during 2.5 h in a pen with three feeders. The silages to be evaluated daily by each experimental unit were allotted randomly to these feeders. Silages harvested at 14:00 achieved highest scores in organoleptic, preference and intake evaluations. Results of preference and intake were similar and the results of PCA ordering of treatments resembled those of odor and texture and were opposite to those of pH and in a lesser extent also to those of aerobic deterioration. The organoleptic evaluation resulted an easy and cheap method to characterize silages, which results were reliable predictors of preference and intake (and hence quality) of alfalfa and orchard grass silages

Clinical, radiological and therapeutic features of keratocystic odontogenic tumours: a study over a decade

Factors associated with the potential for recurrence of keratocystic odontogenic tumours (KCOT) still remain to be clearly determined and no consensus exists concerning the management of KCOT. The purpose of this study was to evaluate different clinical factors associated with KCOT and its treatment methods. A retrospective review was performed of 55 cases treated from 2001 to 2010. Of the 55 cases, 27% were associated with an impacted or semi- impacted tooth. The majority of the lesions (82%) were located in tooth-bearing areas, and the overall mandibular to maxilla ratio of tumour occurrence was 5:1. The treatment options included enucleation, marsupialisation, or peripheral ostectomy, with or without the use of Carnoy ?s solution. Recurrence was found in 14 cases (25%). No significant association was seen between recurrence and age, symptomatic cases, location of the lesion, or unilocu - lar or multilocular appearance. The recurrence rate was higher in the group with tooth involvement, more marked in cases with third molar involvement. Statistical analysis showed a significant relation between recurrence and the type of treatment, with higher rates in cases treated with enucleation associated with tooth extraction. In our series, those cases with a closer relation with dental tissues showed a higher risk of recurrence, suggesting the need for a distinct classification for peripheral variants of KCOT

Severe odontogenic infections : epidemiological, microbiological and therapeutic factors

Objectives: A retrospective study is made of the odontogenic infections treated in La Paz University Hospital (Madrid, Spain) during 2007 and 2008, with an epidemiological and microbiological analysis of a large group of patients.Study Design: A retrospective descriptive study was made, involving the consecutive inclusion of all patients with odontogenic infection requiring admission to our hospital in the period between January 2007 and December 2008. Results: A total of 151 patients were included, with a mean age of 40.3 years and a balanced gender distribution. The most frequently affected teeth were those located in the posterior mandibular segments, caries being the main underlying cause. Most isolates comprised mixed flora, particularly viridans streptococci, different species of Prevotella, Micromonas micros, and different species of Actinomyces. Susceptibility analysis of the microbial isolates showed a high percentage resistance to clindamycin (42.8% of all isolates), particularly among viridans streptococci.Conclusions: The use of antibiotics in head and neck infections requires updated protocols based not only on the existing scientific evidence but also on the epidemiological reality of each center. On the other hand, identification is required of the surgical factors determining infection and how they influence morbidity associated with this type of pathology. © Medicina Oral

Adaptación de la multidimensional sportspersonship orientations scale al contexto español de la educación física

The objective was to analyse the factor structure of the different versions proposed for the Multidimensional Sportspersonship Orientations Scale (MSOS) in the Spanish Physical Education context. The participants were 652 Post-Compulsory and Compulsory Secondary Education students (353 men y 299 women; Mage = 14.98, SDage = 1.59). Confirmatory factor analysis psychometrically supported none of the different versions prosed by the previous works for the MSOS. Nevertheless, the findings underpinned a 17-items 4-factor model (i.e., respect for social conventions, respect for rules and teacher, commitment and respect for classmates) for Physical Education. This structure was invariant across gender. The correlations supported the instrument’s discriminant validity. Reliability analysis reflected suitable values for each factor. In its conclusion, the use of a new factor structure for the MSOS was recommended in the Spanish Physical Education context.El objetivo fue analizar la estructura factorial de las diferentes versiones propuestas para la Multidimensional Sportspersonship Orientations Scale (MSOS) en el contexto español de la educación física. Los participantes fueron 652 estudiantes de educación secundaria y bachillerato (353 hombres y 299 mujeres; Medad = 14.98, DTedad = 1.59). El análisis factorial confirmatorio no apoyó psicométricamente ninguna de las versiones planteadas por los trabajos previos para la MSOS. Sin embargo, los hallazgos sustentaron psicométricamente un modelo de cuatro factores correlacionados y 17 ítems (i.e., respecto por las convenciones sociales, respeto por las reglas, compromiso y respeto por el compañero) para la educación física. Esta estructura fue invariante por género. Las correlaciones sustentaron la validez discriminante del instrumento. El análisis de fiabilidad reflejó valores adecuados para cada factor. Como conclusión, se recomienda la utilización de una nueva estructural factorial para la MSOS en el contexto español de la educación física

Índices de oxidación en aceites de algunas leguminosas del desierto sonorense

The oxidation process of crude and refined oils from wild leguminous seeds: Prosopis juliflora (mezquite), Mimosa grahamii (gatuña), Acacia constricta, (vinorama) Olneya tesota, (palo fierro) Cercidium praecox (palo de brea) and Parkinsonia aculeata (palo verde) were evaluated during storage for 122 days, using corn and soybean oils as controls. Peroxide, Iodine, Acid and p-Anisidine values were determinated during 122 days of storage at room temperature. The wild leguminous raw oils showed results similar to those for the corn raw oil and lower than those of soybean raw oil. This behavior was similar for refinated oils. The rancid odor was detected after 5 days of storage in soybean oil and 40 days in vinorama oil, on the contrary, mezquite, palo verde and palo of brea oils presented this odor after 62 days, and for gatuña’s oil needed 135 days. Our results indicate that legume seed of Sonoran Desert could be a good alternative as source of oil.El proceso de oxidación fue evaluado durante el almacenamiento de los aceites crudos y refinados de las semillas de leguminosas silvestres: Prosopis juliflora (mezquite), Mimosa grahamii (gatuña), Acacia constricta (vinorama), Olneya tesota (palo fierro), Cercidium praecox (palo de brea) y Parkinsonia aculeata (palo verde). Los aceites de maíz y soja fueron empleados como controles. Se determinó el índice de peróxido (I.P.), de Yodo (I.I.), de acidez (I.A), y valor de p-Anisidina (p-A) durante 122 días de almacenamiento a temperatura ambiente. Los aceites crudos de leguminosas silvestres mostraron valores de estos índices similares a los del aceite de maíz crudo y menores que los del aceite de soja crudo. Este comportamiento también fue observado para los aceites refinados. El olor a rancio se presentó en el aceite de soja a los 5 días de almacenamiento, en el de vinorama a los 40 días, en el de mezquite, palo verde y palo de brea a los 62 días y en el de gatuña a los 135 días. Los valores reportados indican que las leguminosas del desierto Sonorense podrían ser una buena alternativa como fuente de aceites
