Authors: Valdés Rodríguez Ofelia Andrea , Muñoz Gamboa Caupolicán , Pérez Vázquez Arturo , Martínez Pacheco Luz Esmeralda
Published: July 2021

Actualmente no existen modelos de crecimiento disponibles para la especie Moringa oleifera en el trópico mexicano, por lo que el objetivo de esta investigación fue analizar curvas de crecimiento de plántulas de M. oleífera bajo condiciones de invernadero y en seis sustratos con diferente contenido nutrimental: arenoso (A), franco-arenoso (FA), arcilloso (AC) y composta de cachaza de caña (C) mezclada en proporciones de A2:C1, A1:C1 y A1:C2. Los análisis de suelos detectaron contenidos de Nitrógeno de 1.5, 1.6, 0.2 y 0% para C, AC, Fa y A, respectivamente. Se realizaron mediciones de longitud y diámetro del tallo, número de hojas, largo y ancho de la hoja, cada cuatro días después de la germinación y durante 36 días. Los grupos de curvas obtenidas fueron comparadas contra tres modelos de crecimiento: Chapman-Richards, Gompertz y Logístico. Se encontraron diferencias significativas en diámetro, altura de tallo y número de hojas entre el sustrato A y los otros a partir de los 20 días (P < 0.05). Los sustratos A1:C1 y A1:C2 permitieron tasas de crecimiento mayores en altura y diámetro de tallo, seguidos del sustrato A2:C1 y los sustratos FA y AC. Los modelos que mejor ajuste tuvieron con las curvas de crecimiento fueron el Logístico, con coeficientes de determinación de 0.96 y Gompertz con 0.95. Se concluye que una combinación A1:C1 fue suficiente para obtener altas tasas de crecimiento en M. oleífera y que los modelos Gompertz y Logístico permitieron predecir este crecimiento en diferentes sustratos durante su fase de vivero.

Published: July 2021

Se evaluaron 10 genotipos de xoconostle de los estados de Hidalgo y Zacatecas, con el objetivo de realizar una caracterización para potenciar su cultivo, uso y comercialización. La mayoría de los frutos de xoconostle evaluados presentaron un color irregular en cáscara o piel, densidad de areolas media, número de glóquidas de baja a media y de color amarillo, la mayor relación longitud-diámetro se observó en xoconostle ‘Borrego’, menor longitud del pedúnculo y mayor longitud ecuatorial (diámetro del fruto) en xoconostles ‘Cambray’ y ´Manzano´, pocas semillas en ‘Manso’ y ´Guinda´, mayor porcentaje de mesocarpio (pulpa) y menor porcentaje de pericarpio (cáscara) en ´Borrego’ y los frutos de Xoconostle ‘Virgen’ y ‘Cambray’ presentaron el menor porcentaje de endocarpio. Al realizar la cosecha de los frutos, tomando como índice de cosecha la menor depresión de la cicatriz del receptáculo, los frutos alcanzaron su madurez óptima de consumo. En años recientes, se ha incrementado la industrialización de productos a base de xoconostle, por lo cual es importante su conservación y la continuación de estudios que ayuden a entender mejor los beneficios que pueden aportar los diversos componentes del xoconostle en la dieta humana.

La ortiga Euphorbiaceae Cnidoscolus multilobus es un arbusto de 3 a 6 m de altura, planta urticante, con jugo lechoso, hojas lobuladas, de aproximadamente 30 cm de largo, flores blancas y florece la mayor parte del año. Crece en el bosque tropical perennifolio y mesófilo de montaña y en sitios abiertos como los potreros. Se le localiza en Atlapexco, Huautla, Huazalingo, Huejutla, Tenango de Doria y Zacualtipán entre otros, en éste último municipio se elabora de forma tradicional un queso fresco a partir de la ortiga, sin embargo, no se tiene información científica sobre su capacidad de coagulación. Por lo anterior se plantó la presente investigación en donde se determinó las diferentes concentraciones de hoja, tallo y raíz en base húmeda y seca para conocer su efecto coagulante. Los resultados obtenidos demuestran que los rendimientos más altos de coagulación fueron en base seca de las tres partes de la planta a las concentraciones de 16 y 20% a 42°C. La hoja en base seca y el tallo en base húmeda presentaron la mayor fuerza de gel a concentraciones de 12, 16 y 20%. Los resultados bromatológicos de la planta en base húmeda y seca se comportaron de forma similar. El mayor porcentaje en la determinación de proteínas fue para tallo en base seca y húmeda con 22.31 y 20.94%. Con respecto a las cenizas la mayor concentración fue para hoja en base seca con 22.16% y en fibra para raíz con 9.57% también en base seca.

Published: July 2021

Como parte de un estudio de la calidad ambiental de Lago de Tecocomulco, Hidalgo, México, fueron colectados los helmintos intestinales de 70 aves de cinco especies: Anas americana, Anas discors, Aythya valisineria, Gallinula chloropus y Fulica americana. Los intestinos de las aves fueron donados por los cazadores locales, transportadas al laboratorio y los helmintos fueron colectados, fijados en AFA y conservados en alcohol etílico (70%) hasta su tinción y montaje. Ocho especies de dos taxa de helmintos fueron encontrados: Digenea-Echinostoma revolutum, Zygocotyle lunata, Echinoparyphium recurvatum, Notocotylus pacifer, Apatemon gracilis, Pseudoapatemon sp.; y Acanthocephala-Polymorphus trochus y Pseudocorynosoma constrictum. Echinostomum revolutum tuvo la mayor prevalencia, abundancia e intensidad promedio en las 36 aves de la Familia Anatidae; una prevalencia de 40% fue encontrada en cada especie de ave de esta familia. Sin embargo, en F. americana (Rallidae), P. trochus tuvo la mayor prevalencia (58.6%), una abundancia de 2.0 y N. pacifer tuvo mayor intensidad promedio (4.3). Echinostomum revolutum y Ps. Constrictum se registran por segunda ocasión en Hidalgo; Z. lunata, N. pacifer, A. gracilis y P. trochus son nuevos registros para las aves en Hidalgo y Pseudoapatemon sp. es un nuevo registro para México. Es importante monitorear los parásitos de las aves acuáticas migratorias en Lago de Tecocomulco ya que sirven como indicadores de la calidad ambiental del lago.

Authors: Castro José Carlos Nahin , Del Ángel Pérez Ana Lid , Hernández Osorio Mabel
Published: July 2021

Para el 2011 el estado de Veracruz contaba con 3,963,610 cabezas de ganado, posicionándose como el principal productor de ganado bovino del país, una ganadería que se desarrolla principalmente bajo el sistema extensivo y que al ir necesitando mayores áreas de pastoreo contribuye significativamente al cambio de uso de suelo y a la vez, cambios de los ecosistemas en donde se desarrolla, entre los que destacan las modificaciones de la estructura de la flora y fauna. Basados en esto y considerando al sector ganadero parte fundamental para la toma de decisiones en cuanto a actividades de conservación se refiere se realizaron 200 encuestas tipo referéndum en la zona Norte, Centro y Sur del estado de Veracruz, abarcando un total de doce municipios con antecedentes de actividades ganaderas. La encuesta solicitaba entre otras cosas, información acerca de la flora y fauna que los propietarios tienen y han visto en sus terrenos, las respuestas se organizaron en matrices y se sometieron a un análisis simple. La fauna se agrupo por clase taxonómica (Mammalia, Aves, Sauropsida) siendo las aves la clase con mayor porcentaje de registros, 53.94, 44.95 y 38.53% para cada una de la zonas. La flora se agrupo de acuerdo al uso que se le da, (forraje, consumo humano, maderable) la vegetación utilizada para consumo humano tuvo el mayor porcentaje de registros para las tres zonas con valores de 42.55, 34.82 y 42% respectivamente. Es importante considerar que los encuestados no mencionaron a los insectos y otros invertebrados de menor tamaño.

A última morte de Lourival: a cisgeneridade como metanarrativa sobre os corpos no jornalismo
Authors: Machado Alisson , Dias Marlon Santa Maria
Published: July 2021

O objetivo do artigo é discutir as formas como a cisgeneridade opera nas racionalidades que orientam as práticas jornalísticas. Essa reflexão é realizada a partir da análise de um caso exemplar: descrevem-se as estratégias narrativas de objetivação e subjetivação encontradas na reportagem televisiva O segredo de Lourival, veiculada em 2019 pelo Fantástico (Rede Globo). Na reportagem, Lourival Bezerra de Sá é apresentado não como uma pessoa transgênera, mas como “uma mulher que se passou por homem durante décadas”. As estratégias apontam para a cisgeneridade como uma metanarrativa, plano de fundo que sustenta o entendimento dos corpos pelo jornalismo, dimensão de caráter fabular e moralista que oblitera a interpretação da complexidade da vida social atuando na manutenção da precariedade dos regimes simbólicos ao ponto de criminalizar as identidades gênero-divergentes.

Natural polymers, specifical mucilages, have been used as a suspending agent for a long period of time. Natural excipients can serve as an alternative to synthetic products since they are less expensive, less toxic, and devoid of environmental pollution. The present study was undertaken to evaluate the mucilage isolated from Tamarindusindica (Fabaceae) seed coat, commonly named tamarind, as an innovative suspending agent. Paracetamol suspensions (10% w/v) were prepared using the T. indica seed coat mucilage as a suspending agent, and it was evaluated for parameters like physical stability, sedimentation profile, dispersibility, and flow property. Furthermore, it was assessed for its stability. The effect of the tested mucilage on the suspension was compared with commonly used suspending agents, i.e. sodium carboxymethyl cellulose (CMC) at concentrations of 0.5, 1.0, and 1.5% w/v. The results obtained indicated that the T. indica seed coat mucilage could be used as a suspending agent.

The most common gynecological malignancies during pregnancy are cervical cancer, followed by malignant ovarian tumors. During pregnancy, gynecological examination is limited and the rate of misdiagnosis is higher. Although the appearance of ovarian tumors during pregnancy is relatively common, most of them are functional and resolve spontaneously. Treatment during pregnancy is related to factors such as tumor size, histological type, gestational age, lymph node involvement and willingness of women to continue the pregnancy. In early-stage malignant tumors, surgery should be planned preferably after 16 weeks of pregnancy and chemotherapy can be administered from the second trimester as in non-pregnant patients. Prognosis is not affected by pregnancy. The result of pregnant woman with ovarian cancer is similar to non-pregnant patients.

Endometrial cancer remains the most common gynecological tumor in women in the United States of America. The simultaneous finding of endometrial and ovarian neoplasm, as a synchronous tumor, accounts for about 5 - 10 % of endometrial and ovarian tumors. Therefore, is a rare entity. Consideration as restricted metastases or pseudometastasis to define the spread of this kind of tumor, is becoming more relevant nowadays thanks to the latest advances in the field of immunohistochemistry and molecular biology. In this article we present the case of a 57-year-old patient initially diagnosed with FIGO stage IIIA endometrial carcinoma; subsequently, it was a synchronous endometrial tumor stage IB and IC ovary, despite the presurgical suspicion of a metastatic tumor. Keywords: Endometrial Neoplasm, Ovarian Neoplasm, Synchronous Neoplasm, Multiple Primary Neoplasm, Neoplasm Metastasis.

Granulose cell tumors represent 2% of ovarian tumors. They are classified as adult type and juvenile type. The juvenile type is associated with precocious pseudopuberty, irregular menstruation or nonspecific symptoms such as abdominal pain and palpable mass. More than 95% are confined to the ovary. A case of a 31-year-old patient is described. The patient consulted for 6-month evolution of increased abdominal volume and weight loss. Right ovary tumor was diagnosed. Tumor excision by gynecological laparotomy with positive frozen cut biopsy and surgical staging were performed. Pathological anatomy reported stromal tumor, and sexual cords suggestive of malignant juvenile granulose cell tumor. Immunohistochemistry reported positive inhibin B. It was concluded as stage IIIA2. This is a rare neoplasm with variable behavior. Accurate diagnosis is based on histological and immunohistochemical studies. Key words: Granulosa, Cell tumor, Juvenile granulosa cell tumor, Ascites, Diagnosis.

Two pot experiments were carried out at lath house in the Nursery of Ornamental Plants, Hort. Dept., Zagazig Univ., Egypt
during the two spring consecutive seasons of 2018/2019 and 2019/2020 to study the effect of water stress (irrigation at 100,
75 and 50 % from field capacity), antioxidants type [(distilled water as control, 4 g/l of calcium carbonate (CC) and 30 g/l of
kaolin (Ka)] as foliar applications and their interaction treatments on growth parameters, physiological traits, drought resistance percentage and some chemical constituents of paulownia seedlings. Plant height, stem diameter, leaf number per plant,
dry weight of leaves per plant, drought resistance index, wood density and total chlorophyll content decreased significantly
with increasing drought treatments from 100% to 50 % field capacity. However, water stress significantly increased soluble
sugar content and proline content in leaves compared to full irrigation treatment. Furthermore, using each calcium carbonate
or kaolin significantly increased all abovementioned parameters compared to control (sprayed with distilled water) in both
seasons. Generally, it could conclude that 30g/l Ka showed a uniform influence in alleviating of Paulownia tomentosa growth
inhibition and its wood density under moderate water stress condition with increasing in drought resistance percentage to reach
105.68 and 102.09 % in the first and second seasons, respectively.
Emerging carbapenem resistance in ESKAPE organisms in sub-Saharan Africa and the way forward
Authors: Njeru John
Published: July 2021

The epidemiology of Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species (ESKAPE) and their role in the development and spread of multidrug resistance (MDR) is not well characterized in sub-Saharan Africa (SSA). Carbapenems possess a broad spectrum of activity and are often reserved for the treatment of MDR infections in developed countries. However, the emergence of carbapenem resistance is increasingly being reported and therefore presents a significant public health threat. Although carbapenems are generally unavailable in African hospitals due to high cost, a small number of studies have reported the occurrence of carbapenem-resistant bacteria (CRB) in SSA. This, therefore, shows that carbapenem resistance (CR) is emerging in Africa. Thus, there is a critical need for deploying robust national and regional multidisciplinary, collaborative, and regulatory approaches aiming at elucidating the epidemiology of CR, its burden on the health care system, and strategies for compacting the development and spread of CR. This report hopes to highlight the epidemiology of carbapenem resistance and the main drivers of antibiotic resistance in SSA and proposes future strategies that can be used to combat the emergence of carbapenem resistance in the region

Bijdragen en Mededelingen betreffende de Geschiedenis der Nederlanden was en is een Nederlands-Belgisch project. Belgische, in de realiteit enkel Vlaamse, historici hebben een rol gespeeld in de redactie en als auteurs van bijdragen. Het aandeel van het Zuiden is altijd kleiner geweest dan dat van het Noorden. Het tijdschrift poogde via een (meestal) paritaire samenstelling van de redactie en initiatieven, zoals comparatief opgezette themadossiers, de balans te herstellen. Aangezien het tijdschrift, zeker wat het Zuiden betreft, nauw verbonden was met de universitaire historische vakgroepen, in het bijzonder die van Gent en Leuven, weerspiegelen de evoluties van dit Belgische aandeel algemene verschuivingen in het academisch bedrijf. Uitbreiding van de onderzoeksfinanciering zorgde voor een aangroei en voor een verjonging en vervrouwelijking van het auteursbestand en van de redactie. Ook andere ontwikkelingen in het historisch bedrijf van de voorbije halve eeuw, zoals het verschijnen van nieuwe tijdschriften en de internationalisering van het onderzoek, hadden een impact op de plaats van het tijdschrift en bijgevolg ook op Vlaamse bijdragen en hun auteurs.Bijdragen en Mededelingen betreffende de Geschiedenis der Nederlanden was and is a Dutch-Belgian project. Belgian, though in fact only Flemish, historians have edited and authored contributions. The share from the South has always been smaller than that from the North. Via a generally balanced composition of the editorial board and initiatives, such as comparatively structured special issues and forums, the journal aimed to restore the balance. Since the journal, especially in the South, was closely affiliated with university history departments, those of the universities of Ghent and Leuven in particular, the evolutions of this Belgian share therefore reflect general shifts in academia. Expansion of research financing brought about accretion, rejuvenation and feminisation of the stock of authors and editors alike. Other developments in historical scholarship from the past half century, such as the appearance of new journals and internationalisation of research, had an impact on the positioning of the journal and consequently on Flemish contributions and their authors as well.

Abstract. Understanding the volatility and mixing state of atmospheric aerosols is important for elucidating the formation of fine particles and to help determining their effect on environment and climate. In this study, the volatility of the fine particles is characterized by the size-dependent volatility shrink factor (VSF) for summer and winter in the urban area of Beijing using measurements of a volatility tandem differential mobility analyzer (VTDMA). We show the volatility of aerosols is always with one high-volatile and one less- or non-volatile mode both in the summer and winter. On average, the particles are more volatile in the summer (with mean VSF of 0.3) than in the winter (with mean VSF of 0.6). The outstanding high-volatile mode around noontime illustrates the role of nucleation in producing more volatile particles in the summer. We further retrieve the mixing state of the ambient fine particles from the size-resolved VSF and find that the non-black carbon (BC) particles that formed from nucleation processes accounted for 52–69 % of the total number concentration in the summer. While, particles containing a refractory core that is thought to be BC-containing particles dominate and contribute 67–77 % toward the total number concentration in the winter. The diurnal cycles of the retrieved aerosol mixing state for the summer further supports the conclusion that nucleation process is the main contributors to non-BC particles. In addition, the extent of aging of BC particles was characterized as the ratio of the BC diameter before and after heating at 300 °C (Dp/Dc), showing that the average ratio of ~2.2 in the winter is higher than the average of ~1.5 in the summer, which indicates that BC aging is more efficient in wintertime, with resulting differences in light absorption enhancement between cold and warm seasons.

Abstract. Geography has long sought to explain spatial relationships between social and physical processes, including the spread of infectious diseases, within the context of modelling human-environment interactions. The spread of the recent COVID-19 pandemic, and its devastating effects on human activity and welfare, represent but examples of such complex human-environment interactions. In this paper, we discuss the value of agent-based models for simulating the spread of the COVID-19 virus to support decision-making with regards to non-pharmaceutical interventions, e.g., lock-down. We also develop a prototype agent-based model using a minimal set of rules regarding patterns of human mobility within a hypothetical town, and couple that with an epidemiological model of infectious disease spread. The coupled model is used to: (a) create synthetic trajectories corresponding to daily and weekly activities postulated between a set of predefined points of interest (e.g., home, work), and (b) simulate new infections at contact points and their subsequent effects on the spread of the disease. We finally use the model simulations as a means of evaluating decisions regarding the number and type of activities to be limited during a planned lockdown in a COVID-19 pandemic context.

Type II diabetes mellitus and its complication are becoming more prevalent in Sudan. The most important predictor of reduction of morbidity and mortality due to diabetes complication is the level of glycemic control achieved. In Sudan diabetes mellitus (DM) is common public health problem, in 2017 about 12% developed serious complications. This study aimed to identify the general characteristics of type II diabetic patients, relevant diabetic characteristics duration, treatment, control and complications. Also to determine level of adherence, and reason behind non adherence medications. A cross-sectional study of randomly selected 360 patients of type II diabetic patient that attend at Al-Daraga Health Center, Wad Madani,Al Kubra locality, Gezira state ,during period from September – October 2020, found that there's statistically significant showed the relation between marital status, socioeconomic status, level of education , Occupation and factors affect adherence in taken medications at ( p value less than 0.05) also There’s significant relation between causes with patients not adhered to used medications (p value 0.000), The socioeconomic status contributed factors in diabetes mellitus complication because the low income level about 213(59.2%). Type II diabetic patients was associated with higher glycated hemoglobin seen among younger age groups. It is also showing the important of Group discussion with the patients to increase awareness of adhering to treatment plan. This study will be helpful in providing evidence regarding the importance of adherence should be emphasized and empowered within the diabetic population.
