Se evaluó el efecto de formulados de Eucalyptus globulus, Jatropha curcas, Petiveria alliacea, Ricinus communis y Ruta graveolens, (A) a concentraciones de 5, 10 y 15 mL.L-1 de agua (B) sobre la mortalidad, inhibición alimentaria y peso de larvas de S. frugiperda. Mediante larvas de segundo y tercer estadio se realizaron bioensayos de aspersión y de elección para evaluar a través de un diseño factorial AxB + 3 testigos [insecticida químico (cipermetrina), botánico comercial (azadiractina) y testigo absoluto (agua)]. De los compuestos botánicos, la mortalidad resultó superior cuando se aplicó aceite de J. curcas (33,7%), e hidrolato de P. alliacea (26,2%) en concentración de 15 mL.L-1. Las Larvas alimentadas con hojas de maíz embebidas con las tres concentraciones de los hidrolatos de P. alliacea y R. graveolens mostraron 71 - 76% de inhibición alimentaria, así como el menor peso. Los resultados mostraron la actividad insecticida de los formulados botánicos evaluados y su potencial para el control S. frugiperda
ACOMPANHAMENTO DO COMPORTAMENTO DO HIV ATRAVÉS DE EXAMES LABORATORIAIS EM PORTADORA DO VÍRUS: RELATO DE CASO
Authors: Oliveira Gissele Cristina Boscardim de , Bonatto Melissa , Cattani Fernanda
Published: June 2022

O vírus da imunodeficiência humana é o agente etiológico da AIDS, doença crônica que destrói o sistema imunológico e é caracterizada pela baixa contagem de células TCD4, alta contagem de partículas virais no sangue e manifestações clínicas da doença. O diagnóstico se dá com o aparecimento de infecções oportunistas, que levam a contagem de TCD4 a níveis menores que 200 céls/mm³. Os exames laboratoriais para o diagnóstico do HIV foram os principais avanços para o início do tratamento, reduzindo a transmissão. Detecção de anticorpos, detecção de antígenos e amplificação do genoma do vírus são alguns dos exames laboratoriais utilizados para diagnóstico. Os dois principais biomarcadores são os exames de contagem de células TCD4, que verifica o sistema imune, e a quantificação de carga viral, que informa a quantidade de partículas virais, mostrando a progressão da infecção. Quanto maior a carga viral, maior o dano ao sistema imune. Uma carga viral indetectável é inferior a 50 cópias/mL, mas valores menores ou iguais a 200 cópias/mL também impedem a transmissão. Uma declaração de consenso afirma que Indetectável é igual a Intransmissível. Portanto, quando indetectável, a transmissão inexiste. O presente estudo relata e discute o caso clínico de uma paciente diagnosticada com HIV/AIDS aos 28 anos, que sobreviveu, apesar do diagnóstico tardio, e sob presença de doença oportunista com um grave grau de diminuição de células TCD4 (22 cél/mm³). Por meio do diagnóstico, introdução e adesão correta da terapia antirretroviral e monitorização de exames laboratoriais, conseguiu evitar a morte e ter uma vida semelhante à de um HIV negativo. Ultrapassou a expectativa de vida que na descoberta era de 10 anos, com uma qualidade de vida considerável, não sendo transmissora do vírus, diminuindo assim o estigma e preconceito. O biomédico é peça fundamental nesse contexto, considerando que deve fornecer informações precisas e fidedignas, tão necessárias ao acompanhamento de pessoas vivendo com HIV, para que autoridades e profissionais de saúde adotem medidas adequadas, tanto na prevenção, quanto no diagnóstico e monitoramento da doença.
MENINGITE BACTERIANA: UMA REVISÃO
Authors: Batista Letícia Franco , Barbosa Silvia Minharro , Dias Felipe Moreira
Published: June 2022

A meningite bacteriana é uma inflamação das leptomeninges que envolvem o Sistema Nervoso Central. Essa patologia, que possui diversos agentes etiológicos, apresenta-se na forma de síndrome, com quadro clínico grave. Entre as principais bactérias que causam a meningite, estão a Neisseria meningitis e Streptococcus pneumoniae. A transmissão ocorre através das vias aéreas por meio de gotículas, sendo a corrente sanguínea a principal rota para as bactérias chegarem à barreira hematoencefálica e, a partir dessa, até as meninges. Atualmente existem vários métodos de diagnóstico precisos, onde a cultura de líquido cefalorraquidiano (LCR) é o método padrão ouro. Ademais, a melhora na qualidade do tratamento com beta-lactâmicos e a maior possibilidade de prevenção, devido à elevação do número e da eficácia de vacinas, vem contribuindo para redução dos casos da doença e de sua gravidade. Porém, apesar desses avanços, ainda há um elevado número de mortalidades e sequelas causadas por essa síndrome.
Patterns of peer interactions in synchronous online English reading classes
Authors:   The Korea Association Of Primary English Education, Rho Ah Ryung
Published: June 2022

The purpose of this study was to analyze patterns of peer interaction between a pair in synchronous online reading classes consisting of twenty-four 6th graders and to examine the effects on patterns with respect to two different pairing conditions; proficiency level and gender. Interaction dynamics among them were identified and evaluated with three elements: equality, contribution, and participation. Seven distinct patterns characterized by the degree of three elements emerged from each pairing condition: 1) For pairs organized by proficiency, expert/expert and novice/novice patterns were seen in homogeneity conditions, while an expert/novice pattern was observed in heterogeneity conditions, 2) For pairs organized by gender, a collaborative pattern and a dominant/passive pattern appeared in homogeneity and heterogeneity condition respectively. Analysis of the patterns suggests high participation and equality from the homogeneity pairs grouped by proficiency and gender. For high affective contribution, homogeneous pairs were effective, while heterogeneous pairs resulted in high academic contribution. With a dearth of studies that explore the nature of students’ interaction in online EFL context, this study hopes to offer an insight into the aspects of pair learning dynamics in an actual online classroom environment.

Authors: Saini Ram Lal , Parveen Seema , Bais Rajni , Prakash Om , Choudhary Anurag
Published: June 2022

Duloxetine hydrochloride was measured by employing Differential Pulse Cathodic Adsorptive Stripping Voltammetry (DP-CAdSV) and Square Wave Cathodic Adsorptive Stripping Voltammetry at the glassy carbon electrode (GCE) in bulk form and human biological fluids. Duloxetine hydrochloride exhibited one distinct and well-defined cathodic peak in the potential range -0.80 to -0.85 V v/s Ag/AgCl/KCl reference electrode. Cyclic Voltammetry, DP-CAdSV and SW-CAdSV showed one reduction wave with peak potential -0.85 V at pH 7. The proposed method's excellent sensitivity was demonstrated by the obtained LOD of 2.233X10-8mol L-1and a LOQ of 7.445X10-8mol L-1bulk by applying DP-CAdSV). On the other hand, a LOD of 5.099X10-8mol L-1and a LOQ of 1.699X10-7mol L-1bulk Duloxetine hydrochloride were achieved by applying SW-CAdSV method. The described methods could be recommended for use in trace analysis, quality control and clinical laboratories.

Published: June 2022

Inspired by the role of intracellular liquid-liquid phase separation (LLPS) in formation of membraneless organelles, there is great interest in developing dynamic compartments formed by LLPS of intrinsically disordered proteins (IDPs) or short peptides. However, the molecular mechanisms underlying the formation of such biomolecular condensates have not been fully elucidated, rendering on-demand design of synthetic condensates with tailored physico-chemical functionalities and responsiveness to specific stimuli a significant challenge. To address this need we have designed a library of LLPS-promoting peptide building blocks composed of various assembly domains. We show that the LLPS propensity, dynamics, and encapsulation efficiency of compartments can be tuned by specific changes to the peptide composition at the single amino acids level, with Raman and NMR spectroscopy proving instrumental in determining the molecular contribution of each side chain to droplet formation. The resulting sequence-structure-function correlation is mandatory for future development of compartments for a variety of applications.
Tackling structural complexity in Li2S-P2S5 Solid-State Electrolytes using Machine Learning Potentials
Authors: Staacke Carsten G , Huss Tabea , Margraf Johannes T , Reuter Karsten , Scheurer Christoph
Published: June 2022

The lithium thiophosphate (LPS) material class provides promising candidates for solid-state electrolytes (SSEs) in lithium ion batteries due to high lithium ion conductivities, non-critical elements, and low material cost. LPS materials are characterized by complex thiophosphate microchemistry and structural disorder influencing the material performance. To overcome the length and time scale restrictions of ab initio calculations to industrially applicable LPS materials, we develop a near-universal machine-learning interatomic potential for the LPS material class. The trained Gaussian Approximation Potential (GAP) can likewise describe crystal and glassy materials and different P-S connectivities PmSn. We apply the GAP surrogate model to probe lithium ion conductivity and the influence of thiophosphate subunits on the latter. The materials studied are crystals (modifications of Li3PS4 and Li7P3S11), and glasses of the x Li2S - (100-x) P2S5 type (x = 67, 70 and 75). The obtained material properties are well aligned with experimental findings and we underscore the role of anion dynamics on lithium ion conductivity in glassy LPS. The GAP surrogate approach allows for a variety of extensions and transferability to other SSEs.
Dipole Switching by Intramolecular Electron Transfer in Single-Molecule Magnetic Complex [Mn12O12(O2CR)16(H2O)4]

Published: June 2022

We study intramolecular electron transfer in the single-molecule magnetic complex [Mn12O12(O2CR)16 (H2O)4] for R = -H, -CH3, -CHCl2, -C6H5, -C6H4F ligands as a mechanism for switching of the molecular dipole moment. Energetics are obtained using the density functional theory (DFT) with onsite Coulomb energy correction (DFT+U). Lattice distortions are found to be critical for localizing an extra electron on one of the easy sites on the outer ring in which localized states can be stabilized. We find that the lowest energy path for charge transfer is for the electron to go through the center via superexchange mediated tunneling. The energy barrier for such a path ranges from 0.4 meV to 54 meV depending on the ligands and the isomeric form of the complex. The electric field needed to move the charge from one end to the other, thus reversing the dipole moment, is 0.01 - 0.04 V/Å.
Correlative Chemical Imaging and Spatial Chemometrics Delineate Alzheimer Plaque Heterogeneity at High Resolution

Published: June 2022

We present a novel, correlative chemical imaging strategy based on multimodal matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI), hyperspectral microscopy, and spatial chemometrics. Our workflow overcomes challenges associated with correlative MSI data acquisition and alignment by implementing 1+1-evolutionary image registration for precise geometric alignment of multimodal imaging data. This enabled multivariate statistical modeling of multimodal imaging data using a novel multiblock orthogonal component analysis approach to identify covariations of biochemical signatures between and within imaging modalities at MSI pixel resolution. We demonstrate the method’s potential through its application towards delineating chemical traits of Alzheimer’s disease (AD) pathology. Here, trimodal MALDI MSI of transgenic AD mouse brain delineates beta-amyloid (Aβ) plaque-associated co-localization of lipids and Aβ peptides. Finally, we establish an improved image fusion approach for correlative MSI and functional amyloid microscopy. This allowed high resolution prediction of correlative, multimodal MSI signatures towards distinct amyloid structures within single plaque features critically implicated in Aβ pathogenicity.

Exchange-Traded Funds Ownership and Stock Volatility
Authors: Choi Byoungho , Jin Shiqing , Hahn Jaehoon
Published: June 2022

This study investigates whether exchange-traded funds (ETFs) increase the nonfundamental volatility of stocks in their baskets via the arbitrage channel. Since the price and the net asset value of the ETF underlying stocks are tied by arbitrage, liquidity shocks to the ETFs may propagate to the underlying stocks through arbitrage trading, which is called the liquidity trading hypothesis. We test the implications of this hypothesis using a sample of ETFs that track the KOSPI200 index. We address the potential endogenous relationship between ETF ownership and stock volatility using the KOSPI200 index reconstitution event as an instrumental variable in the two-stage least squares regression framework; we find the effect of ETF ownership on stock volatility is positive and significant. We also provide empirical evidence that foreign and domestic institutional investors exhibit more frequent trading in the opposite direction and higher-order imbalances for stocks with higher ETF ownership. In summary, our findings suggest that the growth of the ETFs in the Korean stock market may have had an unintended consequence of the higher volatility of ETFunderlying stocks.
Stock Price Responses to Earnings Announcements: Focusing on Investors’ Attention and Market Sentiment
Authors: Fan Jia , Wee Jung-Bum , Kang Hyoung-Goo
Published: June 2022

This study analyzes the impact of investors’ attention, market sentiment, and company characteristics on stock price responses to earnings announcements, using Korean stock market data from 2003 to 2019. First, we find that stock prices respond in the same direction as unexpected earnings, and the significance of stock price response decreases as time passes in the post-event period. Specifically, value stocks respond quickly and appropriately during an event period. The prices of growth stocks tend to overreact to good news during the event period, then show a reversal effect in the post-event period, underreact to bad news during the event period and then adjust through post-earnings announcement drift(PEAD). Second, we find that the stock prices of large and small/medium-sized companies with higher investor attention respond quickly during the event period, and those of small/medium-sized companies with lower investor attention take time to respond. Third, we found that market sentiment does not significantly impact the stock price responses during the event period but positively impacts small/medium-sized companies and growth stock in the post-event and long-term(event period and post-event period combined) periods.

Ultrasound monitoring, both in the form of Doppler and 2D echocardiography, has been used post-dive to detect decompression bubbles circulating in the bloodstream. With large variability in both bubble time course and loads, it has been hypothesised that shorter periods between imaging, or even continuous imaging, could provide more accurate post-dive assessments. However, while considering applications of ultrasound imaging post-decompression, it may also be prudent to consider the possibility of ultrasound-induced bioeffects. Clinical ultrasound studies using microbubble contrast agents have shown bioeffect generation with acoustic powers much lower than those used in post-dive monitoring. However, to date no studies have specifically investigated potential bioeffect generation from continuous post-dive echocardiography. This review discusses what can be drawn from the current ultrasound and diving literature on the safety of bubble sonication and highlights areas where more studies are needed. An overview of the ultrasound-bubble mechanisms that lead to bioeffects and analyses of ultrasound contrast agent studies on bioeffect generation in the pulmonary and cardiovascular systems are provided to illustrate how bubbles under ultrasound can cause damage within the body. Along with clinical ultrasound studies, studies investigating the effects of decompression bubbles under ultrasound are analysed and open questions regarding continuous post-dive monitoring safety are discussed.
A literature review on e-portfolios in teaching writing in English as a Foreign Language classes
Authors: SARAÇ Mehmet , SARAÇ Nilgün , ÖZTÜRK Meral
Published: June 2022

Electronic Portfolios have been widely used for monitoring the progress and achievements of EFL learners as they present a systematic collection of students’ tasks and performances. Particularly during and after the Covid-19 pandemic process, the majority of the educational institutions converted their foreign language teaching models and integrated digital platforms into their teaching programs. With the acceleration of the digitalisation process, e-portfolios have emerged as an alternative to traditional portfolios for monitoring and storing the students’ works. The current paper aims to review the literature on e-portfolios for writing skills in the EFL context. The present review focuses on the effects of e-portfolios on students’ motivation and success, technological requirements and challenges, limitations of e-portfolios, and perceptions of students and teachers/instructors. Depending on the studies reviewed, the paper concludes that e-portfolios affect students’ attitudes toward writing tasks; it increases their motivation and develops writing skills. On the other hand, e-portfolios have some limitations, and they might require certain technological competencies from the instructors’ perspective and call for training both for learners and instructors.

On the restoration of the Arc de Triomphe in Palmyra
Authors: Goloborodskiy Mihail
Published: June 2022

The restoration of the barbarously destroyed Arc de Triomphe has symbolic significance for Syria and Russia. In a situation of significant destruction of the monument, there are opinions suggesting not to restore the monument, but to perceive its ruins as a historical reality. The reconstruction of even completely lost monuments is considered permissible with their important urban planning role. The development of the project for the restoration of the arch in Palmyra will be preceded by its graphic reconstruction, i.e. hypothetical reconstruction of the historical appearance of the monument existing in a ruined state.

The requirements for the precision of materials depending on the categories of land and scale of cartographic materials are considered.
Aux origines du tourisme lent : le sensualisme du XVIIIe siècle et les réorientations du regard du voyageur
Authors: Tatin-Gourier Jean-Jacques
Published: June 2022

La place croissante des descriptions , souvent dénommées "tableaux" dans les récits de voyage du XVIIIe siècle, interroge. Au midi du siècle, cet essor fait pour une part écho à une demande de connaissances objectives que le succès de l'Encyclopédie a indéniablement confortée. Ces connaissances attendues du voyage sont en fait d'ordres très divers : connaissances relevant de l'histoire naturelle (faune, flore, roches etc) mais aussi des moeurs et de l'histoire des pays visités. L'impact des grandes sommes des Lumières (de l'Histoire naturelle de Buffon à l'Encyclopédie et à l'Esprit des lois de Montesquieu) est manifeste. Mais  dans une autre gamme de récits de voyage, plus tardive dans le siècle, il faut également prendre en compte les auto-mises en scène d'un narrateur voyageur de plus en plus attaché à noter ses sensations, ses rêveries, ses sentiments et ses remémorations. Le rythme même du récit de voyage se trouve alors fortement affecté et nécessairement ralenti : les étapes du voyage ne tiennent pas tant à des repères géographiques qu'à la succession de paysages mentaux différents. Les Rêveries du promeneur solitaire de Jean-Jacques Rousseau s'avèrent alors particulièrement suggestives et les polygraphes de la fin du XVIIIe siècle (Louis Sébastien Mercier et Rétif de la Bretonne), dans le récit de leurs déambulations parisiennes, développeront particulièrement ce type d'écriture.
Land Use Change Impact on Normalized Difference Vegetation Index, Surface Albedo, and Heat Fluxes in Jambi Province: Implications to Rainfall
Authors: Azizah Siti Nadia Nurul , June Tania , Salmayenti Resti , Ma'rufah Ummu , Yonny Koesmaryono
Published: June 2022

Jambi covers various land uses with different characteristics related to biogeophysical cycle. Land use plays an important role in the atmosphere-surface interaction and energy balance partition, which influenced rainfall pattern. Two proxies widely used to differentiate various land uses are albedo and normalized difference vegetation index (NDVI). However, study on albedo and NDVI relationship with rainfall in Jambi is still limited. This study aims to analyze the correlation of NDVI and albedo with rainfall and their distribution in Jambi and Muaro Jambi in 2013 and 2017. The research used Landsat 8 OLI TIRS satellite image data to derived NDVI and albedo, and CHIRPS data for rainfall. A simple linear regression was used to calculate the correlation of NDVI and albedo with rainfall. The results showed that the distribution of albedo for each land use class from the lowest to the highest was forest, plantation, cropland, shrubs, and settlements, respectively. On the contrary, the distribution of NDVI and rainfall is the inverse to albedo. Albedo and NDVI had a strong influence on rainfall through surface energy balance partition. This was indicated by the high R-square between albedo and rainfall (0.99) and between NDVI and rainfall (0.97). Increasing upward latent heat flux from the land surface to atmosphere leads to a rainfall increase. In other words, rainfall may also increase with the decrease in albedo, increase in NDVI, or land use change.

Wonder, Empire, Science: The Quagga and Other Extinctions on Display at Naturalis
Authors: Laura Bertens , Wilson Ann Marie
Published: June 2022

Naturalis, the Dutch national museum of natural history, celebrated its bicentennial in 2020 by launching the special exhibition, Nature’s Treasure Trove, featuring 25 ‘crown jewels’ from the collection – of which five are extinct. As a celebratory look back on the museum’s history of collecting, the exhibition navigates tensions between national culpability and national pride: culpability for colonialism and species loss, and pride in the Dutch tradition of scientific discovery. We argue that the exhibition can be seen as an exercise in repurposing a cultural memory that is essential to Dutch national identity, in a world that can no longer ignore the harm done by humans, including the Dutch.
The Appeal of Urgency: Extinction Discourses, Myths and the Private Collectors of Australian Aboriginal Human Remains
Authors: Parker Johanna
Published: June 2022

Extinction presents as a narrative thread in the collecting of Australian Aboriginal human remains in Britain and Australia in the nineteenth and early twentieth centuries. Examples of this narrative are in the correspondence, research and the cataloguing methodologies of private individuals and their interaction with collecting institutions. This article focuses on three case studies that present three different private collecting profiles and intellectual environment interactions: Joseph Barnard Davis (1801–1881), Frederic William Lucas (1842–1932), and William Colin MacKenzie (1877–1938). All three have collections held by major collecting institutions in either Australia or England. These separate and diverse individuals are an important conduit to understanding why the application of the extinction narrative was a factor in transforming Australian Aboriginal human remains into prized specimens, sought by private individuals and public collecting institutions.
Exhibiting Extinction, Recovering Memory, and Contesting Uncertain Futures in the Museum
Authors: Searle Adam
Published: June 2022

This paper builds upon qualitative research in El Museo del Bucardo – The Bucardo Museum – an exhibition space in the village of Torla, high in the Spanish Pyrenees. The bucardo was declared extinct on 6 January 2000 and rose to international fame three years later when scientists in Zaragoza delivered a bucardo clone; this event is commonly portrayed around the world as ‘the first de-extinction’. Taxidermic remains of the last bucardo were absent from public view for years, yet they finally returned to Torla in 2013 following years of campaigning from local activists, and El Museo del Bucardo was founded. I draw upon interviews and archival material to present an environmental history of the bucardo as told through the lens of the museum, one which sets out to ‘recover memory’ and institutionalize the bucardo’s legacy. In the museum, bucardo afterlives continue to shape understandings of situated Pyrenean wildlife. I examine El Museo del Bucardo’s role in generating meaning in an epoch characterized by mass extinction and the spectacle of technofixes in the form of de-extinction science.
Hidden Stories of Extinction: Hawaiian ʻAhuʻula Feather Capes as Biocultural Artefacts
Authors: Westergaard Gitte
Published: June 2022

Natural history museums have been the natural place to find remnants of extinction, but extinction can also be hidden in cultural artefacts. This article identifies certain possibilities and challenges in telling extinction stories through cultural artefacts. Principally, they can reveal different anthropogenic connections to lost biodiversity and challenge our perceptions of extinction and how to restore relationships with what is lost. I illustrate this through the Hawaiian ‘ahu‘ula (cloaks or capes) that were made from feathers of endemic forest birds now extinct or threatened on the islands. By approaching the ahu‘ula as a biocultural artefact, this article points to new ways of telling stories of extinction beyond natural history museums.

El estado de Morelos se caracteriza por la diversidad de especies ornamentales que se cultivan y comercializan tanto en el mercado nacional como internacional. En México anualmente se comercializan aproximadamente 20 millones de plantas terminadas en diferentes tamaños de contenedor con un valor de producción de 718 millones. Los programas de mejoramiento genético de especies cultivadas a cargo de organismos gubernamentales son escasos. La mayor proporción los realizan empresas particulares extranjeras. La nochebuena está sometida al mismo modelo. Ante esta situación el Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias, puso en marcha el Programa de Mejoramiento Genético de Nochebuena en el Campo Experimental Zacatepec, Morelos. La variedad de nochebuena denominada Victoria es producto de este programa y se generó mediante hibridación, selección y técnica de injerto. Victoria es una planta de porte intermedio con ramificación y anchura media. Los atributos sobresalientes de esta variedad son la forma oval de la hoja, el tamaño de esta y la ausencia de lóbulos. La forma de la base de la hoja es redondeada. Las brácteas son de forma elíptica, de color rojo y de tamaño intermedio. El ancho de la cima y el tamaño de la glándula son medios. Se considera una variedad de ciclo intermedio. La respuesta de Victoria es comparable estadísticamente con variedades comerciales y representa una opción para los productores del país con fines de diversificar la oferta en la temporada navideña.

Los principales países productores de fresa son China, Estados Unidos de América y México, los cuales concentran alrededor del cincuenta y nueve por ciento de la producción mundial. Asimismo, los mayores exportadores de fresa son España, Estados Unidos de América y México, que aportan cerca del sesenta y uno por ciento de las exportaciones en el mundo. El objetivo del trabajo es analizar la relación que existe entre las exportaciones de fresa de México a Estados Unidos de América y sus determinantes económicos, entre los cuales destacan el precio unitario de exportación de México, el producto interno bruto de los Estados Unidos de América y la demanda total de importación de fresa de los Estados Unidos de América en el mundo, y calcular las elasticidades precio e ingreso de la demanda de exportación de fresa de México. Los signos de los coeficientes de regresión estimados y las elasticidades precio e ingreso son consistentes con la teoría de la demanda, la variable con mayor influencia en las variaciones de la demanda de exportación es el producto interno bruto de los Estados Unidos de América, la elasticidad precio de la exportación obtenida, menor que uno, refleja que la fresa de exportación es un producto inelástico y la elasticidad ingreso de la exportación, menor que uno, indica que la fresa es un bien normal para los Estados Unidos de América. El modelo de regresión estimado es consistente y congruente con la teoría de la demanda de exportación.
Quitinasas en plantas y posible uso como biomarcadores para el diseño de biosensores en la detección de hongos fitopatógenos

Published: June 2022

La quitina es el biopolímero más importante de la pared celular de los hongos, la cual se degrada por la acción de quitinasas. Las plantas sintetizan estas enzimas para protegerse de factores tanto abióticos como bióticos, incluyendo a los hongos fitopatógenos, los cuales permanecen en estado de latencia hasta encontrar las condiciones adecuadas para manifestarse. Para su identificación, se podrían considerar técnicas basadas en biomarcadores y crear dispositivos que sean rápidos, simples, específicos y confiables, tal es el caso de los biosensores. Se conoce ampliamente la especificidad de las quitinasas con la quitina, por lo que, la identificación de los hongos podría llevarse a cabo mediante un biosensor que integre a las quitinasas. En este manuscrito se revisó información acerca de la síntesis de quitinasas en plantas cuando se someten a estrés, enfocándose en los patosistemas planta-patógeno. Se mencionan también las técnicas y métodos de identificación de los hongos, resaltando el uso de biosensores. Finalmente, se propone la utilización de quitinasas como biomarcadores enzimáticos para su identificación por medio de un biosensor y su aplicación en el control de hongos fitopatógenos.

Los ñätho hñähñu son un pueblo milenario y legítimos dueños de los territorios que hoy comprenden el centro y norte del Estado de México, al paso de los siglos forjan un modo de vida reciproco y complementario con su ambiente creando una cosmovisión integrada a su territorio y un sistema complejo de símbolos que dan origen a su lengua, elemento imprescindible de su patrimonio biocultural y de sus conocimientos que posibilitan estructurar el sistema de saberes agrícolas y desarrollar la milpa y el traspatio -Huähi ne Nxutahngu- e integrarlos a su ambiente como unidad agroecológica insustituible, armónica con su cosmovisión y consistente proveedora de alimentos, medicinas y materias primas el estudio se llevó a cabo de los meses de marzo y septiembre de 2017 y 2018. La praxis agrícola de los otomíes está cimentada en el rescate y revaloración propia de sus conocimientos técnicos, construidos y validados a base de experiencias acumuladas como medios para sortear condiciones climatológicas y geográficas, garantizar su supervivencia y reproducirse como sociedad en un territorio. Es decir, el sistema de símbolos permite colectivizarlos en la acción individual al transferir el saber no sólo del viejo -Xhita- a hijos y nietos, sino entre familias y localidades de la misma etnicidad, validando y colectivizando su función social.
