¿Tiüvame’e mtaaya?: Voz autoral y autoficción en ¡Por la tierra y por la raza! de Juana Belén Gutiérrez de Mendoza

JAIME LOPEZ REYES (2024, [Tesis de doctorado])

"En esta tesis, no hablo de figura autorial sino de voz autoral porque, aunque se relaciona con una puesta en escena de la autora en su texto, sólo me refiero a la realización autorial efectiva en las líneas de ¡Por la tierra y por la raza!, en donde intento atender a la polifonía de su construcción, siempre dentro del universo de la obra. Un estudio más abarcador es necesario para reconstruir la figura autorial, uno que concatene la poesía, el periodismo y la narrativa, sobre todo ese curiosísimo cuento que escribió para sus nietas: el Cuatatapá96 (Gutiérrez y Olivera, 1999)".

Nitrogen fertilizer application alters the root endophyte bacterial microbiome in maize plants, but not in the stem or rhizosphere soil

Alejandra Miranda Carrazco Yendi Navarro-Noya Bram Govaerts Nele Verhulst Luc Dendooven (2022, [Artículo])

Plant-associated microorganisms that affect plant development, their composition, and their functionality are determined by the host, soil conditions, and agricultural practices. How agricultural practices affect the rhizosphere microbiome has been well studied, but less is known about how they might affect plant endophytes. In this study, the metagenomic DNA from the rhizosphere and endophyte communities of root and stem of maize plants was extracted and sequenced with the “diversity arrays technology sequencing,” while the bacterial community and functionality (organized by subsystems from general to specific functions) were investigated in crops cultivated with or without tillage and with or without N fertilizer application. Tillage had a small significant effect on the bacterial community in the rhizosphere, but N fertilizer had a highly significant effect on the roots, but not on the rhizosphere or stem. The relative abundance of many bacterial species was significantly different in the roots and stem of fertilized maize plants, but not in the unfertilized ones. The abundance of N cycle genes was affected by N fertilization application, most accentuated in the roots. How these changes in bacterial composition and N genes composition might affect plant development or crop yields has still to be unraveled.

Seed integrity, effect of temperature and storage time on germination of Populus luziarum and P. primaveralepensis, endangered subtropical species from Mexico

César Jacobo Pereira MIGUEL ANGEL MUÑIZ CASTRO JOSE ANTONIO VAZQUEZ GARCIA Joel David Flores Rivas ALEJANDRO MUÑOZ URIAS FRANCISCO MARTIN HUERTA MARTINEZ (2022, [Artículo])

"Background: Populus luziarum and P. primaveralepensis are endemic species of western Mexico; growing in riparian forests they are critically endangered. The best way to conserve their seeds is unknown, which could be limiting for their conservation.

Hypothesis: The germinability of both subtropical species is like that of boreal and template Salicaceae species that disperse seeds in spring and early summer, as they germinate quickly with high percentages, and rapidly lose their viability when stored at ambient temperature.

Studied species: Populus luziarum and P. primaveralepensis. Study site and dates: Western Trans-Mexican Volcanic Belt. Jalisco, Mexico. October 2019.

Methods: The physical integrity of the seeds was assessed by X-ray imaging and compared with germinability. In addition, the effect of storage time (nine weeks) under two temperatures (4 and 21 °C) on the percentage and mean germination rate was evaluated.

Results: No significant differences were found between physical integrity and germination in freshly collected seeds for both species. Germination in the first 24 hrs was 91 and 95 % for Populus luziarum and P. primaveralepensis, respectively (week 0). Germination percentages were lower when stored at 21 °C, but P. primaveralepensis was decreased more slowly.

Conclusions: Seeds of subtropical Populus respond similarly to those of species from temperate and boreal climates with early seed dispersal, a crucial condition for establishing ex situ reforestation and conservation programs."

Potential impact of prosthetic biomaterials on the periodontium: a comprehensive review.

NATIVIDAD CASTRO ALARCON Artak Heboyan Gustavo Fernandes Norma Samanta Romero Castro (2023, [Artículo])

The success of a prosthetic treatment is closely related to the periodontal health of the individual. The aim of this article was to review and present the importance of prosthetic restorative materials on the condition of the periodontium, the changes that occur in the composition of the subgingival microbiota and the levels of inflammatory markers in gingival crevicular fluid. Articles on the influence of different prosthetic restorative materials on subgingival microbiota and proinflammatory cytokines were searched for using the keywords ¿prosthetic biomaterials¿, ¿fixed prosthesis¿, ¿periodontal health¿, ¿subgingival microbiota¿, ¿periodontal biomarkers¿ and ¿gingival crevicular fluid¿ in PubMed/Medline, Science Direct, Scopus and Google Scholar. The type of material used for prosthesis fabrication together with poor marginal and internal fit can result in changes in the composition of the subgingival microbiota, as well as increased accumulation and retention of dentobacterial plaque, thus favoring the development of periodontal disease and prosthetic treatment failure. Biological markers have helped to understand the inflammatory response of different prosthetic materials on periodontal tissues with the main purpose of improving their clinical application

in patients who need them. Metal-free ceramic prostheses induce a lower inflammatory response regardless of the fabrication method; however, the use of CAD/CAM systems is recommended for their fabrication. In addition, it is presumed that metal-ceramic prostheses cause changes in the composition of the subgingival microbiota producing a more dysbiotic biofilm with a higher prevalence of periodontopathogenic bacteria, which may further favor periodontal deterioration.

Risk, Covid-19 and hospital care in Mexico City: Are we moving toward a new medical practice?

Rubén Muñoz (2023, [Artículo, Artículo])

Covid-19 pandemic has entailed new challenges for health care in the Mexican public health sector, producing changes in clinical practices that are now handling patients infected with covid-19 and also outpatient consultations at tertiary-level care hospitals. Some of these challenges are related to the perception of risk held by physicians regarding the possibility of contracting or transmitting covid-19 during their work,and to the management of risk from the standpoint of biomedical organizational culture linked to the material and symbolic conditions of public health services predating the pandemic. We analyze these issues from a anthropological research based on in-depth interviews to physicians that work with covid-19 patients at “Covid-19 hospitals” or “hybrid hospitals” in Mexico City. Covid-19 has arrived in social relations and perceptions of risk in the arena of health care and involves knowing and transforming some structural and symbolic conditions, resignified with the pandemic, for proper medical care.

La Funcionalidad Física Arrecifal, indicador de la diversidad funcional en ensamblajes de peces de arrecifes en el Parque Nacional Islas Marietas, Nayarit, México

Reef Physical Functionality, indicator of functional diversity on reef fishes assemblages from Islas Marietas National Park, Nayarit, Mexico

Luis Mario Montalvo Jaramillo (2023, [Tesis de maestría])

La ecología funcional se basa en el uso de rasgos funcionales; características de las especies (morfológicas, fisiológicas, comportamiento) medidas a nivel individual que influencian el rendimiento de una especie, siendo de gran utilidad para determinar cambios dentro del ecosistema. El presente trabajo busca evaluar la funcionalidad física como indicador de disponibilidad de hábitat de peces y su relación con la diversidad funcional. La funcionalidad física del arrecife se evaluó mediante el IFA integrando datos de cobertura coralina, complejidad estructural y tasa de calcificación. La estructura de los ensamblajes de peces se analizó mediante el cálculo de índices de diversidad funcional (riqueza, equitatividad y divergencia) con base en cuatro rasgos funcionales (tamaño corporal, movilidad, tipo de agregación y dieta). La relación entre la diversidad funcional del ensamblaje y el IFA se evaluó mediante un análisis de regresión lineal. El IFA fue influenciado de manera positiva por la presencia Pocilloporidos al generar un mayor aporte a la funcionalidad física (FF) y consecuentemente, una mayor provisión de hábitat. Por el contrario, el IFA disminuyó con la presencia de Porites panamensis debido a su baja tasa de calcificación.La diversidad funcional de los ensamblajes no presentó variaciones temporales, atribuible a una baja variabilidad entre los sitios debido a una alta cercanía, baja variacion batimétrica y alta conectividad. La relación entre el IFA y la riqueza funcional de los ensamblajes se atribuye a que sitios con mayor funcionalidad física otorgan disponibilidad de hábitat y refugio contra la depredación a especies crípticas, de talla pequeña y juveniles; ya que, especies de este tipo se asocian a hoyos similares a su tamaño corporal y la supervivencia de las mismas aumenta en sustratos más complejos.

Functional diversity it’s based on functional traits; characteristics of species (morphological, physiological, behavior) measured at individual level that impact their performance and have great utility to determine changes within the ecosystem. This work aims to evaluate physical functionality as indicator of fish habitat availability and its relationship with functional diversity. The physical functionality of the reef was evaluated using the RFI, integrating data on coral cover, structural complexity, and calcification rate. The structure of the fish assemblages was analyzed by calculating functional diversity index (richness, evenness, and divergence) based on four functional traits (body size, mobility, type of aggregation and diet). The relationship between functional diversity and RFI was evaluated using linear regression analysis. The RFI was influenced on positive way for the presence of Pocilloporids due to the great contribution to physical functionality (PF) creating more habitat availability. For the other hand, the RFI was influenced on negative way for the presence of Porites panamensis due their low calcification rate. The functional diversity of the assemblages did not present temporal variations, attributable to a low variability between the sites due high proximity, low bathymetric variation and high connectivity. The relationship between RFI and the functional richness of the assemblages is attributed to fact that sites with greater physical functionality provide more availability of habitat and refuge against predation to cryptic, small and juvenile species; species of this type are associate with holes similar to their body size and their survival increases in more complex substrates.
