Published: April 2023

México se ha convertido en el principal importador de maíz; los pequeños productores utilizan sistemas de producción basados en policultivos con rendimientos bajos. Con el objetivo de desarrollar tecnologías para el cultivo de maíz y frijol se estableció el siguiente experimento. Se probaron tres arreglos topológicos, cultivo simple de maíz y frijol, intercalado de maíz y frijol a una y dos hileras. Se utilizó un diseño completamente al azar, con tres repeticiones por tratamiento. Las variables evaluadas fueron biomasa aérea, rendimiento de grano, índice de cosecha y eficiencia relativa de la tierra (ERT) y, eficiencia relativa de la ganancia (ERG). No fue posible la producción de frijol en este sistema. Los tratamientos de intercalado a dos hileras presentaron los mejores valores para las variables, excepto índice de cosecha. La variedad V-526 tuvo el mayor índice. En el segundo año no se encontraron diferencias entre arreglos topológicos, probablemente debido a la disminución en la precipitación. En ese año el índice de cosecha fue mayor en la variedad VETX-200 UAN. Al igual que en la primera evaluación, la eficiencia relativa de la tierra, el ingreso neto y la eficiencia relativa de la ganancia fue similar en ambas variedades. Para realizar el cultivo intercalado de maíz y frijol es necesario probar otras variedades de frijol. Es posible obtener buenos rendimientos, eficiencia relativa de la tierra y de la ganancia en sistemas intercalados de maíz a doble hilera.
Phosphorus regulates ectomycorrhizal fungi biomass production in a Norway spruce forest

Published: April 2023

Abstract. Ectomycorrhizal fungi (EMF) are important components of soil microbial communities, and EMF biomass can potentially increase carbon (C)
stocks by accumulating in the soils as necromass and producing recalcitrant structures. EMF growth depends on the C allocated belowground by
the host trees, and the nutrient limitation on tree growth is expected to influence this allocation. Therefore, studying EMF production and
understanding the factors that regulates it in natural soils are important to understand C cycling in forests. Fungal mycelium collected from ingrowth mesh bags is commonly used to estimate EMF biomass, but these measurements might not reflect the total
EMF production since turnover rates of the hyphae are not considered. Here we estimated EMF production and turnover in response to
P fertilization (applied as superphosphate) in a Norway spruce forest where nitrogen (N) deposition has resulted in
phosphorus (P) limitation of plant production by using a combination of mesh bags with different incubation periods and with Bayesian
inferences. To test how localized patches of N and P influence EMF production and turnover we amended some bags with a nitrogen source
(methylene urea) or P source (apatite). Additionally, the Bayesian model tested the effect of seasonality (time of mesh-bag harvesting) on
EMF production and turnover. We found that turnover of EMF was not affected by P fertilization or mesh-bag amendment. P fertilization had a negative effect on
EMF production in all the mesh-bag amendments, suggesting a reduced belowground C allocation to the EMF when P limitation is
alleviated. Apatite amendment significantly increased EMF biomass production in comparison with the pure quartz bags in the control plots but not in
the P-fertilized plots. This indicates that P-rich patches enhance EMF production in P-limited forests, but not when P
is not limiting. Urea amendment had a generally positive effect on EMF production, but this was significantly reduced by P fertilization,
suggesting that a decrease in EMF production due to the alleviated P limitation will affect N foraging. Seasonality had a significant
effect on EMF production, and the differences registered between the treatments were higher during the warmer months and disappeared at the end of
the growing season. Many studies highlight the importance of N for regulating belowground C allocation to EMF in northern coniferous forests, but here we
show that the P status of the forest can be equally important for belowground carbon allocation to EMF production in areas with high
N deposition.

Abstract. Satellite radar backscatter contains unique information on land surface moisture, vegetation features, and surface roughness and has thus been used in a range of Earth science disciplines. However, there is no single global radar data set that has a relatively long wavelength and a decades-long time span. We here provide the first long-term (since 1992), high-resolution (∼8.9 km instead of the commonly used ∼25 km resolution) monthly satellite radar backscatter data set over global land areas, called the long-term, high-resolution scatterometer (LHScat) data set, by fusing signals from the European Remote Sensing satellite (ERS; 1992–2001; C-band; 5.3 GHz), Quick Scatterometer (QSCAT, 1999–2009; Ku-band; 13.4 GHz), and the Advanced SCATterometer (ASCAT; since 2007; C-band; 5.255 GHz). The 6-year data gap between C-band ERS and ASCAT was filled by modelling a substitute C-band signal during 1999–2009 from Ku-band QSCAT signals and climatic information. To this end, we first rescaled the signals from different sensors, pixel by pixel. We then corrected the monthly signal differences between the C-band and the scaled Ku-band signals by modelling the signal differences from climatic variables (i.e. monthly precipitation, skin temperature, and snow depth) using decision tree regression. The quality of the merged radar signal was assessed by computing the Pearson r, root mean square error (RMSE), and relative RMSE (rRMSE) between the C-band and the corrected Ku-band signals in the overlapping years (1999–2001 and 2007–2009). We obtained high Pearson r values and low RMSE values at both the regional (r≥0.92, RMSE ≤ 0.11 dB, and rRMSE ≤ 0.38) and pixel levels (median r across pixels ≥ 0.64, median RMSE ≤ 0.34 dB, and median rRMSE ≤ 0.88), suggesting high accuracy for the data-merging procedure. The merged radar signals were then validated against the European Space Agency (ESA) ERS-2 data, which provide observations for a subset of global pixels until 2011, even after the failure of on-board gyroscopes in 2001. We found highly concordant monthly dynamics between the merged radar signals and the ESA ERS-2 signals, with regional Pearson r values ranging from 0.79 to 0.98. These results showed that our merged radar data have a consistent C-band signal dynamic. The LHScat data set (https://doi.org/10.6084/m9.figshare.20407857; Tao et al., 2023) is expected to advance our understanding of the long-term changes in, e.g., global vegetation and soil moisture with a high spatial resolution. The data set will be updated on a regular basis to include the latest images acquired by ASCAT and to include even higher spatial and temporal resolutions.

El principal factor de riesgo que predispone al desarrollo de lesiones epiteliales e intraepiteliales, que posteriormente prosperan en neoplasia cervicouterina, es la infección por el virus del papiloma humano. Se realizó un trabajo de investigación de tipo retrospectivo, transversal y descriptivo con el objetivo de analizar los factores relacionados con el desarrollo de lesiones preneoplásicas y neoplásicas cervicouterinas y su conexión con las actividades preventivas y salud reproductiva en mujeres de diversas edades.
El universo estudiado estuvo comprendido por 41 pacientes de sexo femenino que asistieron al gabinete semiológico de la Universidad Privada del Valle para la toma de muestras para examen (endocérvix y exocérvix) histopatológico de Papanicolau, cuyas edades oscilaron entre los 19 y 60 años. Los resultados muestran que el 100 % de los pacientes tienen un grado elevado de riesgo (PAPIII) y las lesiones displásicas presentan infección por el virus del papiloma humano. El promedio de edad fue de 38,4 años en pacientes con lesiones displásicas intraepiteliales. El número de embarazos llegados a término promedio por los pacientes con un grado de PAP alto era de 3. Los agentes etiológicos causales de inflamación con mayor predominancia fueron Candida albicans en un 48,78 % y Gardnerella vaginalis en un 43,9 %.
Se concluye que los principales factores de riesgo para el desarrollo de lesiones intraepiteliales inflamatorias preneoplásicas son la infección por Virus del Papiloma humano, la edad y el número de embarazos llegados a término.

El índice de necesidad de tratamiento ortodóncico se desarrolló en el Reino Unido por Brook y Shaw en 1989. Este índice prioriza y clasifica las maloclusiones según las necesidades de tratamiento. Se realizó un estudio de tipo descriptivo, transversal y observacional con el objetivo de determinar el grado de maloclusión y la necesidad de tratamiento ortodóncico en los pacientes de la Especialidad de Ortodoncia de la Universidad Autónoma de Nayarit del 2014 al 2017, donde se evaluaron 202 modelos de estudio de pretratamiento de ortodoncia de la clínica de dicha universidad con un calibrador digital marca Mitutoyo, una computadora y el programa Microsoft Office Excel para tabular la información y realizar la estadística descriptiva. Los resultados muestran que el componente de salud dental presentó un promedio de 2,51 ± 1,07 (donde el 84,3 % necesitaba algún tipo de tratamiento de ortodoncia). El promedio del componente estético fue de 4,9 ± 2,54 y tan sólo el 45,61 % necesitaba ortodoncia. Respecto al componente de salud dental, el 83,51 % de las mujeres y el 85,14 % de los hombres necesitaba algún tipo de tratamiento de ortodoncia. Sin embargo, sólo el 44,33 % de mujeres y el 48,65 % en hombres necesitaba algún tipo de tratamiento de ortodoncia. Se concluye que existe una mayor necesidad de tratamiento de ortodoncia al utilizar el componente de salud dental que cuando se utiliza el componente estético. Los hombres presentaron una mayor necesidad de tratamiento de ortodoncia que las mujeres al evaluarlos con ambos índices.

La gingivitis ulcero necrotizante es una infección gingival aguda en la cual se presenta infeccion e inflamación de los tejidos periodontales. Se caracteriza por necrosis y ulceración de la papila gingival, dolor y sangrado espontáneo, sabor desagradable y halitosis, con invasión bacteriana principalmente de espiroquetas y fusobacterias. A medida que la gingivitis ulcero necrotizante progresa, se produce la pérdida extensa de hueso, por lo que esta es una enfermedad grave y notable.
En su etiología están implicados factores dependientes de la microbiota con fenómeno de invasión y factores relacionados con el huésped (alteración capilar e inmunológica y desnutrición). Se presenta un caso clínico de gingivitis ulcero necrotizante en un paciente masculino de 23 años, quien recibió el tratamiento respectivo con resultados muy satisfactorios; además, se discutió la importancia de tomar en cuenta un programa de soporte y mantenimiento eficaz con revisiones periódicas para disminuir el riesgo de recurrencias.

Published: April 2023

Los dientes supernumerarios son un problema de desarrollo muy frecuente en niños. El mesiodens es un diente supernumerario presente en la línea media entre los incisivos centrales. Su etiología no está totalmente clara, aunque se considera la hiperactividad de la lámina dental como factor determinante. Entre las complicaciones que puede dar lugar el mesiodens están: retraso en la erupción, erupción ectópica, rotación de los incisivos permanentes y diastema en la línea media lo cual altera la oclusión y por consiguiente la estética. Otros hallazgos que se cree que se deben a la presencia de dientes supernumerarios son la reabsorción de la raíz de dientes permanentes, formación de quistes, y erupcion del diente supernumerario en la cavidad nasal. Por lo tanto, es importante que el clínico diagnostique el mesiodens oportunamente para permitir un tratamiento óptimo pero minimo, el mismo que consiste en la remoción quirúrgica de la pieza supernumeraria. La intervención oportuna no solo previene la maloclusión sino también el tiempo necesario para la corrección de la ortodoncia.
El objetivo del presente trabajo es informar del abordaje quirúrgico y ortodóntico de un paciente masculino de 8 años, para el tratamiento de un diente supernumerario y la ausencia del incisivo central derecho. En conclusión, la presencia de un mesiodens produce el retraso de la erupción de los incisivos superiores, signo que debe alertarnos para un diagnóstico y tratamiento oportuno.

Military Conflict in Fourteenth-Century Castile and the Rise of Mayorazgo
Authors: Villalon Andrew 
Published: April 2023

ABSTRACT
Mayorazgo is a conditional property tenure that arose in the central Iberian kingdom of Castile during the later Middle Ages and by 1500 had come to dominate property holding within that kingdom’s aristocracy. An estate held in mayorazgo could not be alienated from the family’s possession or divided among heirs. Instead, it had to be passed down intact to the next in line. Mayorazgo continued as a significant economic force in Iberia until its disestablishment in 1836. While primarily utilized for holding landed wealth, a family mayorazgo could also incorporate rents and material items, such as money, arms and armor, artwork and books, documents—in short, anything the family wished to maintain possession of over time. Although the origins of mayorazgo date at least as far back as the mid-thirteenth century, this form of tenure underwent a great expansion during and because of warfare that dominated the peninsula during the second half of the fourteenth century—warfare that brought the Trastámaran dynasty to the throne when Enrique II “the Bastard” assassinated his legitimate half brother, Pedro I “the Cruel,” and seized the throne. This article examines mayorazgo and how the wars of the period promoted its growth.
Questioning Sardità―Approaches to Island Identity Issues in the Mediterranean
Authors: Hock Jonas , Linzmeier Laura 
Published: April 2023

ABSTRACT
This article analyzes a bundle of tensions tied to the (self-)representations of the larger Mediterranean subnational islands: island-specific identities are often used in aspiring to political independence and in moving toward linguistic unification, even when they run counter to historically evolved complexity and contemporary cultural heterogeneity. Taking Sardinia as an example, this article questions the construction of sardità along two main axes: language policy and literary production. The authors begin by noting that Sardinian often serves as an umbrella term for several local linguistic varieties whose attribution to that language is in part contested. The authors next assert that the self-conception of the islanders, as reflected in Sardinian literature, is also partly stamped by outside perspectives. Focusing on the case of Sardinia, but with comparative outlooks on Corsica and Sicily, this article shows that the tensions between homogenization trends and cultural-linguistic complexity undermine and at the same time found claims of island exceptionalism.

Published: April 2023

This study was conducted to compare the nutrient utilization,concentration of some rumen metabolites, blood urea nitrogen and somephysiological responses to water restriction in Sudan desert sheep andNubian goats. Three yearling uncastrated intact males from each species,averaging 18.37 kg (for sheep) and 13.21 kg (for goats), were randomlyallotted to four treatments in a completely randomized block design witha 2 x 2 factorial arrangement of treatments to determine the effects ofanimal species and water restriction. Both species were offered either adlibitum feed and water or water restricted to 50% of ad libitum level withad libitum feed. Animal species resulted in a significant (P<0.01) increasein dry matter intake, water intake, faecal dry matter and respiration rateand a decrease (P<0.01) in water intake: dry matter intake ratio in sheepcompared with goats. Sheep showed also higher (P<0.05) urine volumevalue than goats. Rectal temperature was not affected by animal species.Dry matter intake, faecal dry matter and urine volume decreasedinsignificantly with water restriction. However, water intake and waterintake: dry matter intake ratio decreased significantly (P<0.01) withtreatment. Rectal temperature and respiration rate values were almostsimilar at the two levels of water intake. Species x treatment interactionshowed a significant (P<0.01) increase in water intake in sheep comparedwith goats given water ad libitum. Water intake, however, decreased inboth species as a result of water restriction. Animal species induced asignificant effect on the apparent digestibility coefficients of dry matter,organic matter, crude protein, crude fibre, nitrogen free extract and totaldigestible nutrients. Ether extract digestibility did not differ betweenspecies. Goats had lower digestibility coefficients and total digestiblenutrients compared with sheep. Except for ether extract digestibility, the
