"Los probióticos son bichos diminutos cuyo consumo genera efectos benéficos en la salud. De hecho, la palabra probiótico significa 'pro-vida'. Algunas levaduras, como la utilizada para hacer pan o cerveza, pueden ser probióticos para animales y humanos. Desde hace algunos años, los estudios con la levadura Debaryomyces hansenii han demostrado que ésta es un probiótico. Se ha demostrado que, administrada por vía oral, esta levadura tiene efectos estimulantes del sistema de defensa y beneficios para la función digestiva de animales terrestres y acuáticos. Por lo anterior, se describen los hallazgos que revelan que D. hansenii es un probiótico para animales y posiblemente para humanos."

"Probiotics are tiny bugs that when consumed have beneficial effects on health. In fact, the word probiotic means pro-life. Some yeasts, such as that used to make bread or beer, can be probiotics for animals and humans. For some years, studies with the yeast Debaryomyces hansenii indicate that it is a probiotic.

This yeast administered orally has been shown to have stimulating effects on the defense system and beneficial effects on the digestive function of terrestrial and aquatic animals. Therefore, we will try to describe the findings of D. hansenii that indicate that it is a probiotic for animals and possibly also for humans."

Debates contemporáneos sobre la eficacia de los derechos humanos en la globalización

ROBERTO MARTINEZ REGINO HECTOR ALEJANDRO RAMIREZ MEDINA (2023, [Libro])

En esta obra se abordan temáticas vinculadas a las demandas sociales que se han convertido en una fuente de interés y de preocupación para la academia y que, además, son el resultado del esfuerzo constante y persistente de posturas científicas que han permitido la apertura y el continuo desarrollo de líneas de investigación para la innovación del conocimiento susceptible de aplicación. Hoy en día, cualquier actividad humana a nivel individual o social, así como las actividades de la sociedad civil organizada o incluso de las instituciones del Estado están necesariamente vinculadas con los dos grandes ejes de la obra que tiene el lector en sus manos: los derechos humanos y la globalización.

En ese orden de ideas, no es de sorprendernos que las investigaciones académicas aquí presentadas sean visiones contemporáneas de cambios coyunturales y de propuestas de cambio a la estructura de las sociedades y que se interrogan sobre la vigencia del Contrato Social.

Habitability conditions for floods: the case of Tuxtla Gutiérrez, Chiapas, Mexico

MARCELINO GARCIA BENITEZ Saul Nucamendi Hernandez Omar Ávila Flores (2022, [Artículo, Artículo])

At present, there are changes in the environment that favor the presence of extreme climatic phenomena such as floods, this exposure implies that the populations of urban areas suffer effects on their material assets, which limits their capacity for individual and / or family development. Given the lack of local territorial planning, the establishment of colonies was allowed on the banks of the Sabinal river and its tributaries that present episodes of flooding during the rainy season (Sistema Municipal de Protección Civil, 2015).

The study evaluates the habitability conditions of the urban population exposed to flooding, the city of Tuxtla Gutiérrez, Chiapas is taken as a reference, since historically it is a recurring problem during the summer. The methodology interrelates geostatistical, spatial and cartographic databases with hemerographic information sources based on the review of the literature for the construction of the general index, determined in dimensions that group social, economic, educational aspects, availability of basic services, goods with those that count the dwellings and their accessibility, etc., on a geographical scale of Urban Geostatistical Areas (AGEB).

The results obtained generated an index on the distribution of habitability conditions by urban Ageb, they are interrelated with spatial data on floods and their relationship with Sustainable Development Goal 11 (ODS), which proposes to improve infrastructure conditions in cities and towns. sustainable communities so that the inequality originated among the population exposed to future extreme flood events that occur in the different areas that make up the city is reduced.

The potential of UAV and very high-resolution satellite imagery for yellow and stem rust detection and phenotyping in Ethiopia

Gerald Blasch David Hodson Francelino Rodrigues (2023, [Artículo])

Very high (spatial and temporal) resolution satellite (VHRS) and high-resolution unmanned aerial vehicle (UAV) imagery provides the opportunity to develop new crop disease detection methods at early growth stages with utility for early warning systems. The capability of multispectral UAV, SkySat and Pleiades imagery as a high throughput phenotyping (HTP) and rapid disease detection tool for wheat rusts is assessed. In a randomized trial with and without fungicide control, six bread wheat varieties with differing rust resistance were monitored using UAV and VHRS. In total, 18 spectral features served as predictors for stem and yellow rust disease progression and associated yield loss. Several spectral features demonstrated strong predictive power for the detection of combined wheat rust diseases and the estimation of varieties’ response to disease stress and grain yield. Visible spectral (VIS) bands (Green, Red) were more useful at booting, shifting to VIS–NIR (near-infrared) vegetation indices (e.g., NDVI, RVI) at heading. The top-performing spectral features for disease progression and grain yield were the Red band and UAV-derived RVI and NDVI. Our findings provide valuable insight into the upscaling capability of multispectral sensors for disease detection, demonstrating the possibility of upscaling disease detection from plot to regional scales at early growth stages.

Elevación del piso del seno maxilar con técnica transcrestal.

SALVADOR REYES FERNANDEZ NORMA SAMANTA ROMERO CASTRO NATALIA HERNANDEZ TREVIÑO DANIEL SANDOVAL GUEVARA XENIA TERESA COBOS CRUZ (2023, [Artículo])

Introduction: the elevation of the transcrestal floor of the maxillary sinus consists of the vertical reconstruction of the atrophic alveolar ridge in an apical direction, with which it is possible to place the correct number and length of oral implants. Objective: to describe the procedure of a case of transcrestal maxillary sinus floor elevation with the placement of three dental implants. Clinical case: 62 year old female patient with missing teeth 16, 25 and 26. Treatment: three implants were placed to replace the missing teeth. Due to the decrease in height of the remaining alveolar ridge due to pneumatization of the maxillary sinuses, elevation of the sinus floor was planned with the transcrestal Summers¿s technique and placement of graft material. Results: by means of the grafts, sufficient height was achieved for the correct stability of the implants, each área had an average gain of 3 mm in bone height, with which length was obtained to give the implants adequate primary stability. Conclusion: sinus floor elevation with a transcrestal approach is a good alternative for rehabilitation with implants in the posterior edentulous sector, associated with pneumatization of the maxillary sinuses.

LIZBETH FITZ BELTRÁN (2023, [Otro, Trabajo terminal, especialidad])

La aspiración de secreciones es una técnica que realiza el personal de enfermería que consiste en

la extracción de secreciones traqueobronquiales con ayuda de un sistema de presión en pacientes

intubados Este procedimiento en este tipo de pacientes debe ser totalmente estéril y adecuado

antes, durante y después de la aspiración, ya que nuestro objetivo es proporcionar al paciente un

estado de bienestar y confort, mantener la permeabilidad de la vía aérea y un adecuado intercambio

gaseoso, estimular el reflejo tusígeno y evitar el desarrollo de una infección respiratoria debido al

acúmulo de secreciones.

El siguiente trabajo es un estudio de tipo cuantitativo con método observacional y de corte

transversal, se espera que el personal de enfermería de las áreas donde se encuentran pacientes con

intubación orotraqueal unifiquen conocimientos sobre la técnica de aspiración de secreciones con

una propuesta de capacitación sobre la técnica de aspiración de secreciones , se tomara una muestra

de conveniencia de 47 enfermeros de los servicios de UCIA A, sala de hombres, sala de mujeres

2 y urgencias . Se realizará la capacitación al personal de enfermería sobre la técnica de aspiración

de secreciones tanto sistema abierto como cerrado, esto ayudará al personal de enfermería a realizar

correctamente la técnica de aspiración de secreciones, ayudando tanto al paciente como a la

institución ya que se evitarán complicaciones hacia el paciente, así como, disminución en estancia

hospitalaria.

Secretion aspiration is a technique that nurses doing to extract tracheal secretion with the help of

pressure system in mecanical ventilation patientes. With this kind of patient, the secretion

aspiration procedure must be sterile technique before during and after, because our goal is get to

the patient a well-being state and confort, holding permeability on the airway and gas exchange

suitable, increased sputum expectoration and avoid respiratory tract infections.

Hot Extremes and Climatological Drought Indicators in the Transitional Semiarid-Subtropical Region of Sinaloa, Northwest Mexico

OMAR LLANES CARDENAS OSCAR GERARDO GUTIERREZ RUACHO Iván Hernández Romano ENRIQUE TROYO DIEGUEZ (2022, [Artículo])

"The main goal of this study was to explore the historical and recent spatial concurrence between the frequency (F), duration (D) and intensity (I) of hot extremes (HEs) and the frequency and evolution of meteorological drought in the region of Sinaloa. Based on the values of daily maximum temperatura (Tmax) and precipitation obtained from CLImate COMputing for the interval April–October of a historical period (1963–2000) and a recent period (1982–2014), the HE and the standardized precipitation index (SPI) were calculated on one-month (SPI-1) and four-month (SPI-4) timescales. Spearman rank correlation coefficients (Sr) were used to obtain the significant concurrences (SCs) between HEs and SPI-1, and HEs and SPI-4. El Quelite weather station showed the highest historical SCs between HEs and SPI-1 (−0.66≤Sr≤−0.57). Jaina is the only station that showed SCs with all four indicators of HEs and SPI-4 (−0.47≤Sr≤−0.34). In this study, the concurrence between HEs and SPI-1, and HEs and SPI-4 was determined for the first time. These are phenomena that can decrease the crop yield, particularly for rainfed crops such as maize, sesame and sorghum in the region commonly known as “the breadbasket of Mexico."
