Importance of Human Breast Milk in the Early Colonization of Streptococcus mutans
No full textBackground and objectives: The development of the oral microbiome begins in the prenatal
stage. Breast milk contains antimicrobial proteins, microorganisms, metabolites, enzymes, and
immunoglobulins, among others; therefore, differences have been noted in the type of microorganisms
that colonize the oral cavity of children who are breastfed compared to those who are formula-fed.
Our objective was to establish the relationship between breastfeeding, formula feeding, or mixed
feeding (breastfeeding and formula) with the presence of S. mutans in a population of children under
6 months of age. Materials and Methods: The patients were recruited from the Child Care Center of
Ciudad Juárez, Chihuahua, and from the pediatric dentistry postgraduate clinics of the Autonomous
University of Ciudad Juárez; children exclusively fed maternally, with formula, and/or mixed were
included. Those who had been fed within the previous hour were excluded. The sample was taken
with a smear of the jugal groove using a sterile micro-brush. For the identification of Streptococcus
mutans, a culture of Mitis Salivarius Agar (Millipore) was used. Results: 53.3% corresponded to
females and 46.7% to males, 36.7% corresponded to maternal feeding, 23.3% corresponded to formula
feeding, and 40% corresponded to mixed feeding. In 90% of the infants, the parents indicated that they
did not perform oral hygiene. The CFU count showed that infants who were exclusively breastfed
had an average of 9 × 10 CF/mL, formula-fed infants had an average of 78 × 10 CFU/mL, and those
who had mixed feeding 21 × 10 CFU/mL. Conclusions: According to the results obtained, it was
possible to corroborate that exclusive breastfeeding limits the colonization of Streptococcus mutans
compared to those infants who receive formula or mixed feeding; these results could have a clinical
impact on the dental health of infants by having a lower presence of one of the main etiological
factors involved in dental caries and the type of microbiome established in the oral cavity
Populismo mediático e interculturalidad política en México.
No full textEl presente trabajo intenta trazar una línea argumentativa para analizar los diferentes esfuerzos del populismo mediático en su intención de establecer una narrativa con tintes y aspiraciones pedagógicas, de referentes político - culturales, claramente dirigidas a un sector ideológico y emocional de la ciudadanía, así como el proceso de edificación de un lenguaje claramente en oposición y hasta cierto punto confrontacional con otras dimensiones y formas de analizar el imaginario público

Tecnología solar para obtención de agua en regiones áridas
No full textSe ha desarrollado un dispositivo que utiliza energía solar para obtener agua dulce en regiones áridas. Este avance responde a la escasez global de agua, que afecta a más de 2.2 mil millones de personas. El dispositivo usa geles porosos que pueden adsorber y desorber humedad simultáneamente, ofreciendo una solución eficiente y sostenible. Puede capturar entre 1.18 y 6.43 gramos de agua por cada gramo de gel poroso, incluso en condiciones de humedad del 30 al 60%. Este avance promete mejorar la calidad de vida en áreas con acceso limitado a agua potable
Visibilizando el trastorno disfórico premenstrual
No full textEn este escrito se exploran las áreas clave para entender el trastorno disfórico premenstrual (TDPM), así como las investigaciones más recientes sobre su prevalencia, factores de riesgo y sus consecuencias. Además, se pone en evidencia la falta de información sobre este trastorno y la necesidad de mayor atención en este campo. El artículo resalta la importancia de investigar y concienciar sobre el TDPM, que afecta entre el 5% y el 8% de las mujeres y puede impactar significativamente su calidad de vida. Finalmente, se destaca la relevancia de realizar estudios continuos que mejoren la comprensión del trastorno y permitan una atención oportuna. Aunque los profesionales de la salud están cada vez más conscientes del TDPM, esta información no siempre llega al público en general, lo que dificulta la educación y la sensibilización. Como resultado, los síntomas de las mujeres que lo padecen suelen ser ignorados o minimizados por su entorno

Emotions and social representations of distance education in university students from Chihuahua during the Covid-19 pandemic
No full textThis article analyzes the social representations that university students developed during the period of confinement due to the COVID-19 pandemic, particularly regarding their decision to continue their studies despite the challenges posed by the closure of educational institutions. The study is based on the situation in the northwest region of Chihuahua, encompassing at least 10 municipalities. This study utilized a mixed descriptive research approach, involving a survey comprising 69 items. The survey was conducted in the spring of 2021 among 313 students from five different academic programs within the Multidisciplinary Division of the UACJ in Nuevo Casas Grandes. Findings revealed that students, during the pandemic, had negative experiences with long distance education, primarily due to issues such as emotional management, time management skills, and poor technological access. These challenges resulted in negative emotions, although students did not perceive a decline in academic performance or disruptions in interactions with teachers or peers
