RICE SEED TREATMENTS BY SOAKING IN WATER AND THREE PESTICIDES (CARBOSULFAN, BENOMYL, AND IMIDACLOPRID) TO CONTROL FOLIAR NEMATODE Aphelenchoides besseyi
Authors: Ajri Miftahul , Indarti Siwi , Sumardiyono Christanti
Published: September 2023

Aphelenchoides besseyi is one of the most important parasitic nematodes in rice plants, capable of dormancy in rice seeds. This study aims to determine the effects of soaking rice seeds in water and pesticides (carbosulfan, benomyl, and imidacloprid) on the mortality of A. besseyi, seed viability, and symptoms in rice seedlings. This study specifically used rice seeds infected with A. besseyi. Cold water treatment (cwt) at 5-10˚C for 24 hours followed by hot water treatment (hwt) at 52˚C for 10 minutes caused 51.17% A. besseyi mortality yet reduced the seed viability. Soaking the seed in the water at 25-30˚C for 24 hours followed by hwt at 57˚C for 10 minutes and hwt at 52˚C for 10 minutes could cause 48.67%, 39.18% and 33.05% nematode mortality, respectively. Low nematode mortality in all treatments (less than 60%) showed symptoms of A. besseyi infection in rice seedlings 21 days after planting. Seed dressing with imidacloprid 5WP (2% by seed weight) caused 47.25% A. besseyi mortality, whereas benomyl 50WP (0.2% by seed weight) and carbosulfan 25ST (2% by seed weight) caused only 27.61% and 11.34%. Based on two parameters (nematode mortality and seed viability), the most effective treatments were soaking the rice seeds in the water at 25-30˚C for 24 hours and seed dressing with imidacloprid.
Deciding Town Hall’s Best Business Development Area from PT. Batu Bara Berjaya (PT. BBB)
Authors: Multazam Dimash T. Achmad , Hermawan Pri
Published: September 2023

In contrast to earlier years, the Town Hall currently serves as a multifunctional space encompassing a park, a recreational facility, and a venue for fulfilling one’s daily physical training requirements. Batu Bara Berjaya (BBB) and its staff, including contractors and subcontractors, are currently seeking an increase in visitor numbers. This thesis aimed to identify authentic challenges, ascertain the optimal business line for Town Hall, and explore strategies for Town Hall to effectively compete with other prominent attractions in East Kutai, thereby reclaiming its position as the preferred destination. The research methodology integrates both qualitative and quantitative descriptive approaches. The data collection process involved the administration of questionnaires, conducting interviews, making field observations, and reviewing relevant literature. In qualitative analysis, data is subjected to various analytical techniques such as Stakeholder Analysis, Kepner-Tregoe Analysis (K-T Analysis), 5 Whys Analysis, Porter’s Five Forces Analysis, and Value Co-Creation Analysis. On the other hand, quantitative analysis involves using the Analytical Hierarchy Process (AHP) Analysis to process data. The study’s findings demonstrated that applying the Analytic Hierarchy Process (AHP) suggests that the Town Hall ought to prioritise developing the Sports Centre. Subsequently, the Culinary Area and Hangout Places should be considered as secondary options. According to Porter’s Five Forces framework, the Town Hall can be classified as operating moderately. Alternatively, it could be subject to competition in its role as a tourist destination, notwithstanding the challenges associated with accessing it. Furthermore, the researchers propose utilising the Value Co-Creation Analysis framework to convert town halls into viable and enduring tourist destinations.
The results of the study indicate that based on AHP calculations, the Town Hall should prioritize the Sports Center as the primary development option, followed by the Culinary Area and Hangout Places. Then, based on Porter's Five Forces, the Town Hall is at the Moderate level, or it can be contested again to compete as a place to visit, despite the difficulty of the path. And ultimately, the authors of this study suggest employing the Value Co-Creation Analysis framing to transform town halls into sustainable visitor destinations.

Authors: Akhmad Akhmad , Khalid Idhan , Asdar Asdar
Published: September 2023

The current development of Gowa Regency is directed at efforts to develop economic activities that can provide welfare to the people of Gowa Regency. This study aims to formulate a strategy for developing small micro enterprises (MSMEs) in Gowa Regency. Data collection was carried out by conducting in-depth interviews with cooperative and MSMEs service staff in Gowa Regency, and MSMEs entrepreneurs in Gowa Regency. Apart from the interviews, a Focus Group Discussion (FGD) was also conducted. The data obtained were then analyzed using descriptive analysis and SWOT analysis. The results of the study show that the strengths possessed by MSMEs  in Gowa Regency are, increase public interest in doing business and local government support for MSMEs development. Weaknesses faced include coordination of coaching by each Regional Apparatus Organization (OPD) and the absence of a training center. While opportunities for MSMES development include: the availability of natural resources and the position of Gowa Regency which is directly adjacent to the city of Makassar as the provincial capital. Furthermore, the challenges faced include; more competitive entry of products from Java and abroad, as well as dependence on raw materials from Java and imports. Therefore the MSMEsdevelopment strategy in Gowa Regency can be carried out with a program to create a healthy business climate for MSMESs with the aim of facilitating the establishment of a healthy, economical, and efficient and non-discriminatory business environment for the continuity and improvement of MSMEs performance.

JAVANESE MEDICINAL MEASURE LEXICONS (NUMERAL CLASSIFIERS) IN SERAT PRIMBON RERACIKAN JAMPI JAWI
Authors: Sinungharjo F.X. , Adji S.E. Peni , Adji F. Tjandrasih
Published: September 2023

Traditional medicine in a global context has been observed widely in several countries. Research on traditional medicine has not been massively conducted in Indonesia, especially in Java. The present research, in response to the area of this subject, is an initial study to observe and examine the traditional medicine in Java, especially the medicine measurement system recorded in Serat Primbon Racikan Jampi Jawi. The measure system in traditional medicine has various lexicons as has been revealed in the lexicalization of numeral classifiers and the cultural context of the measurement system in traditional medicine recorded in Serat Primbon Racikan Jampi Jawi. The theoretical perspectives are composed of culture, semantics, and lexicography; using note-taking techniques as the data collection, dictionary method as the data analysis, definition and meaning description as the data presentation as well as its meaning relations. Based on the observation, there were 77 (seventy-seven) Javanese measure lexicons consisting of 60 (sixty) base words, 5 (five) affixed words, and 13 (thirteen) word combinations in Serat Primbon Racikan Jampi Jawi. Meaning relations found from the lexicons were abstract meaning relations by using 7 (seven) concepts of retrieval and concrete features with 6 (six) compositional constructions. The measure was obtained from 9 (nine) other fields of lexicon and was used to measure 25 (twenty-five) types of ingredients with one-to-one relations, one-to-two or more relations, and two or more-to-one relations. This research indicated that (1) The form of language adapts to the creativity and references in the measure; (2) The meaning of the measure characterizes the experience and knowledge of the Javanese people on the traditional medicine system in their everyday life; and (3) The measure system is the answer to the needs, specifications, and inheritance of the local wisdom of the Javanese people, particularly in the field of traditional medicine.

Lex-Mercatoria Principles: A keystone in International Commercial Arbitration
Authors: Al Bitar Rachid
Published: September 2023

The international Commercial Arbitration is a dispute resolution mechanism; thus, it allows the parties to a dispute to settle their affair outside the national courts. On the other hand, lex mercatoria can be defined as a body of rules that encompasses usages and customs that were used by the merchants in the medieval ages, thus the English nomination “merchant law’. After globalization, more specifically in the twentieth century, both above-mentioned concepts have been developed and adopted by most of the legal systems around the world. This paper aims to define lex mercatoria by exploring its’ history, its’ development, and by tackling all its’ elements to study the impact of lex mercatoria’s principles on international commercial arbitration proceedings.

Linguistic Embodiment of Values in Internet Media Discourse: A Corpus Analysis of Representative Contexts (the Lexeme ‘po-khoroshemu’)
Authors: Radbil T. B.
Published: September 2023

This article explores the linguistic and discursive mechanisms of value embodiment in internet media discourse, as well as the scientific tools for identifying and qualifying them in a corpus of textual data. The study investigates the peculiarities of metalanguage usage of the lexeme ‘po-khoroshemu’ [‘in a good sense of the word’] as a representative context for detecting values of a particular type, referred to as “pseudovalues,” which express relative evaluation: ‘something is good in some respect, but bad in another respect.’ Corpus analysis methodology was employed, using materials extracted from newspaper corpora within the Russian National Corpus. The study demonstrates that the metalanguage expression ‘po-khoroshemu’ serves as a kind of “test” for identifying potential negative evaluativity in nominations that, according to contemporary societal trends, could be perceived as “good” or neutral / non-evaluative. On the other hand, it is established that this representative context indicates an increase in the value register for nominations that are default negatively evaluative. The conclusion is drawn that through the use of the lexeme ‘po-khoroshemu,’ certain evaluations can be imposed on the readership of media texts, which may not have been initially shared by the addressees, thus making the metalanguage expression ‘po-khoroshemu’ an effective means of linguistic manipulation.
Romanticism in Works of Su Manshu and Yu Dafu: National Characteristics
Authors: Zakharova N. V.
Published: September 2023

The article examines the literary movement of romanticism as a creative method employed by Su Manshu and Yu Dafu, two Chinese writers of the first half of the 20th century. The novelty of the research lies in the comparative analysis of the works of these two popular literati, whose prose had a significant influence on the formation of modern Chinese literature. It is reported that the interest of Chinese writers in romantic sentiments was fueled by their exposure to European literature through translations into Japanese and Chinese. Both writers referred to themselves as romantics, but their reasons for being drawn to this artistic method were different. Su Manshu was captivated by the new genre features, such as biographies written from the author’s perspective rather than focusing solely on historical figures, which was sanctioned by traditional literature. Yu Dafu was attracted to the romantic artistic style for its ability to employ unconventional expressive means in Chinese literature. At the same time, the romantic compositions of both writers carry markers of national identity. For Su Manshu, this is evident in the portrayal of female characters, while for Yu Dafu, it is manifested in the use of nature imagery to convey the mood of the characters. The article highlights that the development of romanticism in Chinese literature has been insufficiently studied by Russian sinologists and holds prospects for further research.
Epithets in Russian Spiritual Verses
Authors: Kotov A. A. , Mukhina E. A.
Published: September 2023

The article examines the composition and functioning of epithets in Russian spiritual verses. The relevance of the study is due to the lack of research on spiritual verses from a linguistic perspective, as well as the opportunity to explore the interaction between oral and written traditions, secular and Christian culture, which are closely intertwined in this folklore genre. A brief overview of the theory of epithet study in Russian linguistic tradition is provided, taking into account the latest research, with particular emphasis on the use of constant epithets in folklore texts of various genres. The texts of three collections of Russian spiritual verses are considered: “Collection of Russian Spiritual Verses” compiled by V. Varentsov; “The Dove Book: Russian Folk Spiritual Verses of the 11th-19th Centuries”; “Spiritual Verses of the Russian North”. Two corpora of epithets are distinguished: general folklore constant epithets and genre-specific epithets of Russian spiritual verses. Observations are made about their quantitative and qualitative composition, describing the peculiarities of their usage in relation to the genre’s specificity and explaining their correlation. A grammatical characterization of epithets is provided from the perspective of morphological expression and position within an attributive syntagm.
Activities of Fedor Sannikov as a Supervisor of Schools in Ekaterinburg (1747—1751)
Authors: Safronova A. M.
Published: September 2023

This article examines, for the first time, the activities of Fedor Sannikov as the superintendent of Yekaterinburg schools, based on archival documents. It is noted that he had to fulfill his duties in a difficult environment, as tensions arose between him and the administration. As a result, his proposals were likely intentionally delayed or rejected. Despite the unfavorable attitude and even resistance from his superiors, Sannikov made every effort to modernize the schools. In particular, he insisted on reintroducing parallel vocational training for students, as introduced by V. N. Tatishchev according to a document from 1736. Sannikov repeatedly made proposals to increase the number of teachers in the arithmetic school, where he taught over 100 students. It has been established that under the supervision of the superintendent, there were more than 270-280 students in Yekaterinburg schools by the mid-18th century, and Sannikov was aware of the financial situation, abilities, and academic achievements of each of them. In the conditions of rising costs in the late 1740s, he proposed training students in crafts and allowing them to work in workshops in the second half of the day, as the students’ government stipend was not enough for clothing, shoes, food, and many had to rely on charity. Sannikov also paid attention to the education of noble children whose parents were not inclined to send them to schools.
German Colonists of Northwest Russia in Conditions of Post-Revolutionary Reality (1918-1922)
Authors: Shaidurov V. N. , Lomanov V. A.
Published: September 2023

The focus of this publication is on the history of the German village of the North-West of the RSFSR in the first post-revolutionary years (1918—1922). The economic and political life of the German rural population is characterized, including the resolution of land issues, economic activities, requisition policies of the Bolshevik leadership towards them, as well as the formation and functioning of Soviet and party bodies in areas with high concentrations of Germans. The condition and functioning of German farms largely depended on the extraordinary revolutionary economic measures carried out by the Bolsheviks within the framework of equalizing land use and “war communism”, where the German village was considered as an easily accessible and high-performance source of agricultural resources for the Red Army and the urban population, which resulted in an excessively high economic burden on the colonies and a selective approach to accounting for national the specifics of the economic life of the Germans and their current economic opportunities. German peasants mostly negatively perceived post-revolutionary innovations, and service in Soviet and party bodies was used as a tool to protect and promote their personal economic interests and to protect them from possible repressive measures.
El desborde de la palabra. Tres casos de literatura electrónica mexicana
Authors:   , Villalobos López Vladimir
Published: September 2023

Se explora el origen y las características generales de la literatura electrónica. Tras considerar las particularidades de estos objetos literarios, se plantea una metodología de análisis para las obras electrónicas y se aplica dicha metodología en tres casos creados por autores mexicanos. Esta metodología, centrada en el estudio del espacio, la estructura, el lenguaje y la lectura de los objetos literarios, se aplica a la obra sonora de Ulises Carrión, Poet’s Tongue, al videojuego Mulaka y al bot literario unBotMás. Las tres obras, seleccionadas por su representatividad en el ámbito mexicano y por su correspondencia con las tres generaciones de literatura electrónica existentes, permiten demostrar los alcances de la metodología propuesta, así como plantear una serie de conclusiones en torno a la creación de literatura electrónica mexicana, tanto sobre su creación como acerca de su lectura y sus relaciones con lo digital.
El soneto en México en el siglo XX: tradición y renovación
Authors:   , Mugica Saavedra Manuel Marcos , Flores Flores Ociel
Published: September 2023

Investigación que tiene como propósito mostrar la diversidad de adaptaciones que la figura poemática del soneto —en contraposición con la forma canónica— ha sufrido desde su invención en el siglo XIII hasta nuestros días, de manera general en América Latina y particularmente en México. Para conseguirlo se brinda un repaso por la historia del soneto; también se analizan las dificultades más frecuentes para analizarlo, aquellas que provocan equívocos, desde malos entendidos con la métrica y sus licencias hasta sesgos conductuales que niegan la heterogeneidad en la llamada figura reina de la poesía. Asimismo, se da constancia de los mayores cambios que ha tenido la estructura tradicional, mismos que se inician con el Modernismo, en donde la experimentación con la forma deja de remitirse a eventos aislados y comienza a facturarse como sistema poético [manifestación estética] y como una postura ante el mundo, cuyo presupuesto es la emancipación escritural y cultural de España [manifestación ética]. El seguimiento de las modificaciones que los poetas le han hecho a la estructura clásica pretende sostener la hipótesis de que el rasgo más característico del soneto en el siglo XX es el camuflaje (entendido como figura retórica), el ocultamiento de la forma ortodoxa, para desautomatizar la lectura y generar nuevos vínculos entre el poema y el lector. Para conseguirlo se recurre al verso moderno, al bloque tipográfico, a la polimetría o la prosa, hasta llegar a lo que llamo soneto conceptual, con lo que el panorama del soneto se amplía tanto para los poetas como para los estudiosos de la forma.
Análisis de los personajes femeninos en la narrativa fantástica de Ana de Gómez Mayorga y Guadalupe Dueñas
Authors:   , Estrada Huitrón Saida
Published: September 2023

Fiel a su esencia, la literatura fantástica se ha caracterizado por surgir como ruptura dentro de la tradición literaria universal. Opuesto a la estimación de algunos lectores, ésta no representa una fuga de la realidad; por el contrario, establece una forma discursiva a través de la cual personajes y lectores se enfrentan al cuestionamiento de la realidad. Así, lo fantástico rompe con los paradigmas bajo los que se ejerce la crítica ante situaciones que, en diversos contextos, han sido destinadas al silencio como la violencia, la otredad y las enfermedades mentales; pero bajo la pluma de las y los escritores, salen a la luz cual epifanía para desestabilizar al mundo como lo percibimos. No es gratuito que su proliferación se dé a la par de contextos de cambio, si recordamos que en México lo fantástico fue cultivado con mayor ahínco por diversos escritores durante la conocida Generación de Medio Siglo. Es necesario reconocer también que el género sirvió de antesala para la profesionalización de varias escritoras, que hoy en día están siendo consagradas como representantes importantes de lo fantástico dentro de la tradición literaria mexicana como: Ana de Gómez Mayorga, Guadalupe Dueñas, Elena Garro, Amparo Dávila, Inés Arredondo, Adela Fernández. En la actualidad, el desarrollo de diversas investigaciones dedicadas al análisis de obras literarias de corte fantástico ha permitido que el género comience a ser considerado en diversos programas de estudio estableciendo una apertura dentro de la configuración del canon; además posibilita líneas de estudio como esta tesis, que no sólo busca reivindicar vida y obra de escritoras del género que han sido poco estudiadas como Ana de Gómez Mayorga o Guadalupe Dueñas – cuya amplia producción cuentística facilita el abordaje crítico de relatos no estudiados–, sino que ofrece un análisis de la forma en la que se representan los personajes femeninos inmersos generalmente, en circunstancias adversas.
Performance and emissions of water-emulsified diesel fuel in an IDI diesel engine under varying engine load
Authors: Oliveira Pedro , Brójo Francisco
Published: September 2023

This paper aims to verify the possibility of utilising water-in-diesel emulsions (WiDE) as an alternative drop-in fuel for diesel engines. An 8% WiDE was produced to be tested in a four-stroke, indirect injection (IDI) diesel engine and compared to EN590 diesel fuel. An eddy current brake and an exhaust gas analyser were utilised to measure different engine parameters such as torque, fuel consumption, and emissions at different engine loads. The results show that the engine running on emulsified fuel leads to a reduction in torque and power, an increase in the specific fuel consumption, and slightly better thermal efficiency. The highest percentual increment of thermal efficiency for WiDE is obtained at 100% engine load, 5.68% higher compared to diesel. The emissions of nitric oxide (NO) and carbon dioxide (CO2) are reduced, but carbon monoxide (CO) and hydrocarbons (HC) emissions are increased, compared to traditional diesel fuel. The most substantial decrease in NO and CO2 levels was achieved at 75% engine load with 33.86% and 25.08% respectively compared to diesel.

Identification of water stress-tolerant edible pumpkin seed (Cucurbita pepo) genotypes using seed yield-based tolerance indices
Authors: Seymen Musa , Dursun Atilla , Yavuz Duran , Kurtar Ertan Sait , Türkmen Önder
Published: September 2023

Pumpkin is usually cultivated in arid and semiarid regions, and the lack of water stress-tolerant cultivars is a major limiting factor. Therefore, this study was carried out to identify superior water stress-tolerant genotypes. For this purpose, 44 inbred lines with superior agronomic traits were selected from the gene pool. In addition, two hybrids (G1-Mert Bey F1 and G2-Sena Hanim F1) and two landraces (G3-Hatun Tırnağı and G4-Cercevelik) with high commercial value were used as commercial cultivars. The water stress indices were calculated from seed yields from the pumpkin genotypes grown in irrigated and water stress conditions in 2017 and 2018. The stress tolerance index (STI) determines tolerant and superior genotypes. From the principal component and cluster analyses’ findings, G9, G40, G32, G36, G5, G11, G22, G30, G37, and G13 showed the highest water stress tolerance among the inbred lines. During future breeding experiments, these inbred lines may have significant potential for developing novel water stress-tolerant cultivars for pumpkin cultivation in semiarid regions.
Comparison of the yielding of plum, sour cherry, and sweet cherry trees trained to a trellis for mechanical harvesting of fruit with those trained to a leader
Authors: Buler Zbigniew , Rabcewicz Jacek , Białkowski Paweł
Published: September 2023

In 2014, plum, sour cherry and sweet cherry trees were planted in an experimental plot of the Institute of Horticulture – National Research Institute at a distance of 4.5 m between rows and, depending on the cultivar, every 1.5, 2.0 and 2.5 m in a row. The trees were trained in the shape of the letter ‘Y’, with the shoots raised at an angle of 20° or 30° to the horizontal, intended for mechanical harvesting of dessert fruit with a harvester attached to a tractor. The two tree canopy formation systems at both shoot inclination angles were compared with the standard spindle crown with a vertical leader, from which the fruit was picked by hand. After 3 years of training the trees, mechanical harvesting of dessert fruit began with a harvester designed at the Institute of Horticulture in Skierniewice. The trees formed in the shape of the letter ‘Y’ produced comparable yields, and also higher and lower yields, depending on the cultivar, in comparison with the trees trained to a spindle crown.
Localisation of active substances in Hedera helix leaves and Linaria vulgaris shoots used in pharmaceutical and cosmetic industry
Authors: Konarska Agata
Published: September 2023

Although Hedera helix and Linaria vulgaris are considered toxic plants, their extracts containing many bioactive compounds are commonly used in the pharmaceutical and cosmetics industries. Plant secretory structures are considered the primary site of synthesis and accumulation of many valuable metabolites. The presence of secretory structures and the location of active substances in H. helix leaf petioles and L. vulgaris inflorescence shoots were detected using light microscopy and histochemical and fluorescence tests. The analyses showed schizogenic secretory ducts in the H. helix petioles and capitate glandular trichomes on the surface of the L. vulgaris shoots. The secretion and secretory cells of the H. helix ducts and the L. vulgaris trichomes contained acidic and neutral lipids, sesquiterpenes, polyphenols, tannins, flavonoids, phenolic acids, neutral and acidic polysaccharides, proteins and alkaloids. Data on the secretory structures and taxonomic and morpho-anatomical traits of the analysed raw materials may help evaluate their quality (falsification).

Authors: Kalisz Andrzej , Kornaś Andrzej , Húska Dalibor , Zelinka Radim , Sękara Agnieszka , Pokluda Robert , Sałata Andrzej , Gil Joanna
Published: September 2023

Engineered TiO2 nanoparticles (TiO2-NPs) are broadly produced and utilized in various consumer products. However, plant uptake of NPs may lead to disruptions in physiological and metabolic processes, particularly when the plant’s defense mechanisms are overwhelmed. In this study, sweet pepper seedlings were exposed to TiO2-NPs via foliar (2.5% suspension) and root (0.5% suspension) methods, with plants treated with distilled water serving as controls. Results showed that foliar application caused higher accumulation of Ti in leaves as compared to stems, while root exposure led to a higher increase of Ti content in stems than in leaves. Additionally, foliar application led to alterations in chemical composition of the plants, including changes in malondialdehyde (MDA), L-ascorbic acid, total phenolics content, carotenoids, in total antioxidant capacity (TAC) and antioxidant enzymes activity. Root exposure also affected enzyme activity and TAC, but also altered H2O2, MDA and glutathione content. Chlorophylls remained at stable level in the leaves of the seedlings. Overall, these studies provide important information on plant-nanoparticle interactions and the potential effects of different nanoparticle application strategies. These data indicate also that the specific nanoparticles, applied at a controlled manner, have potential to boost the plant metabolism and improve stress tolerance, which is an important factor affecting crops’ quality and productivity.
A newly recognized family of the Ascoidea (Acari: Mesostigmata: Gamasina), based on a revised concept of the subgenus Lasioseius (Endopodalius) Christian and Karg, 2006

Published: September 2023

The systematic position of the subgenus Endopodalius Christian and Karg, 2006, previously recognized by Lindquist and Evans, 1965, as the scutalis species group in Lasioseius, is reviewed. Based in part on plesiomorphic structures of the female sperm access system being of a laelapoid type, it is removed as a subgenus of the blattisociid genus Lasioseius in the superfamily Phytoseioidea and accomodated as a separate genus within the superfamily Ascoidea. In other respects, adult females of this taxon are so distinctive apomorphically to justify separate family group recognition, Endopodaliidae, fam. nov., tentatively related as a sister-group to the morphologically and behaviorally more derived Antennochelidae Lindquist and Moraza, 2014. Species of this family are tropical, their adult females phoretic on beetles of various families of the infraorder Cucujiformia, suborder Polyphaga. A diagnosis of the family and revised description of Endopodalius based on adult females and males are presented, with an updated key to world recognized species of the genus, including the following new binominal combinations, Endopodalius americanus (Chant,1963), Endopodalius mouchei (Loots, 1980), and a new synonym: E. scutalis (Banks, 1914) (= E. prorsoperitrematus Abo-Shnaf et al., 2016). A lectotype is designated from type material of Hypoaspis scutalis Banks, 1914.
Mesenchymal stem cell licensing: enhancing MSC function as a translational approach for the treatment of tendon injury
Authors: Koch Drew W. , Schnabel Lauren V.
Published: September 2023

Tendon injuries are common in both veterinary and human clinical patients and result in morbidity, pain, and lost athletic performance. Consequently, utilizing naturally occurring injuries in veterinary patients as a comparative model could inform the development of novel therapies and increase translation for the treatment of human tendon injuries. Mesenchymal stem cells (MSCs) have shown considerable efficacy for the treatment of experimental and clinical superficial digital flexor tendon injury in the horse; however, the reinjury rate following treatment can remain high and MSC efficacy in treating other tendons is less well known. Additionally, the translation of MSC therapy to human tendon injury has remained poor. Recent evidence indicates that naïve MSC function can be enhanced through exogenous stimulation or manipulation of their environment. This stimulation or activation, herein termed MSC licensing, markedly alters MSC functions associated with immunomodulation, extracellular matrix remodeling, vascular development, bioactive factor production, and endogenous stromal/progenitor cell support. Additionally, a variety of licensing strategies has proven to influence MSC-secreted factors that have positively influenced outcome parameters in both in vitro and in vivo disease models separate from musculoskeletal tissues. Therefore, identifying the optimal licensing strategy for MSCs could ultimately provide an avenue for reliable and repeatable treatment of a broad range of tendon injuries of both veterinary and human clinical patients. This article details current evidence on the effects of licensed MSCs in both in vitro and in vivo disease models of different species and provides commentary on how those effector functions identified may be translated to the treatment of tendon injuries.

La disponibilidad y aprovechamiento del recurso hídrico actualmente es un problema que afecta el desarrollo de la vida y de actividades económicas. A pesar de que Ecuador es uno de los países con mayor disponibilidad de agua por habitante, el aumento de la demanda ejerce presión sobre las vertientes de abastecimiento. El presente estudio tuvo por objetivo determinar la escasez hídrica en la subcuenca del río Ambi, ubicada en la provincia de Imbabura en Ecuador, durante el periodo 1990 –2017. Para ello, se determinó el índice de escasez hídrica (IEH) mediante el cálculo de la oferta y demanda hídrica usando los Sistemas de Información Geográfica. La oferta hídrica se calculó con el uso del modelo hidrológico SWAT y los caudales simulados fueron validados con información recopilada desde el Instituto de Meteorología e Hidrología de Ecuador (INAMHI). Como resultados se obtuvo que, durante el periodo 1990 – 2017, el valor promedio de la oferta hídrica fue de 4.94 m3/s y su demanda hídrica total fue de 17 m3/s. Esto demuestra que mientras la oferta disminuye la demanda aumenta. Además, los valores obtenidos para el IEH se triplican desde el periodo 1990-1996 hasta el periodo 2007-2018 al pasar de 57.26% a 183.57%. En consecuencia, los resultados evidencian la alta presión ejercida desde la demanda a la disponibilidad de recursos hídricos.

Authors: Reis Brenda , Quadros Ângelo , Pinheiro Raisa
Published: September 2023

Objectives: to describe the epidemiological profile of patients with non-cystic fibrosis bronchiectasis in a pediatric hospital and to expand the knowledge of this comorbidity in the pediatric population. Methods: Chest CT scans performed from January 2016 to January 2020 in a pediatric care service were selected. The reports were consulted, verifying those with compatible criteria currently accepted for the diagnosis of bronchiectasis. The medical records of those selected underwent a review process in search of the variables analyzed. Patients diagnosed with cystic fibrosis and with outdated medical records were excluded. Results: Of the 2319 reports studied, 42 patients were identified. Among these, 59.5% were female, 66.7% were followed up at a pneumopediatrics outpatient clinic, and the mean age at the time of imaging diagnosis was 9.3 years (±4.9). At follow-up, 57.1% of patients underwent spirometry and 35.7% underwent sputum culture. The most observed bacterial growth was that of Pseudomonas aeruginosa (33.4%) and the most frequent spirometric pattern was restrictive (29.2%). Of the presumptive etiologies, the most prevalent was recurrent pneumonia (21.4%), followed by bronchiolitis obliterans (14.3%) and collagen diseases (14.3%). Conclusions: The results found in this study allowed a better characterization of this subgroup of patients. In addition, the importance of diagnosing non-cystic fibrosis bronchiectasis is reinforced, as its therapy requires specific and individualized management.
