Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support is
often essential for patients who experienced cardiac arrest. Although
lactate levels have been considered during hemodynamic management in
such cases, some patients with normal hemodynamics and oxygenation
exhibit elevated lactate levels due to the influence of underlying
diseases such as sepsis and malignant tumors. In contrast, urinary
liver-type fatty acid-binding protein (L-FABP), a biomarker of renal
ischemia and acute systemic ischemic injury, is less likely to be
affected by these factors, indicating that it may be a more sensitive
hemodynamic indicator than lactate. However, no previous reports have
discussed the use of L-FABP during VA-ECMO management of patients with
severe ischemic injury after cardiac arrest. Herein, we discuss a case
in which L-FABP measurements were used to manage a 46-year-old male
patient receiving VA-ECMO support. His mean blood pressure was ≥ 75 mmHg
for the first 24 h after the initiation of VA-ECMO, and he experienced a
rapid decrease in both L-FABP and lactate levels, the patterns of which
were similar. Weaning him off VA-ECMO was eventually successful based on
the combination of mechanical settings, echocardiographic parameters,
and hemodynamic indices. The current case suggests that measurement of
L-FABP levels can aid in selecting the target mean blood pressure,
determining whether to increase or decrease the flow rate of VA-ECMO,
and determining whether weaning from VA-ECMO is appropriate. As L-FABP
levels can be measured in approximately 10 minutes, they may have
substantial clinical value when rapid decision-making is required.
Determination of the dynamic characteristics of a gear pump by the load variation method using special bench systems
Authors: Sanchugov V. I. , Rekadze P. D. 
Published: July 2022

Introduction. Some of the major factors in the occurrence of vibration of units, causing fatigue failure of the housings of elements, pipelines, and failure of pump elements, are pulsations of the working medium in the hydraulic systems of machine tools, fuel feed systems of aircraft engines and liquid-propellant engine supply. This study aimed at the implementation of a method for determining the dynamic characteristics of a volumetric pump using special bench systems, and the comparison of the calculation results to the experimental data. The stages of calculating the dynamic characteristics of a volumetric pump were described, taking into account the pre-developed special bench systems on the example of an external gear pump with a capacity of 14 cm3 /rev. The implementation of V. P. Shorin's load variation method using special bench systems developed by the authors with predetermined dynamic characteristics was shown. The main stages of the methodology for determining the dynamic characteristics of a gear pump were described.Materials and Methods. Methods of spectral analysis of pulsating pressure were applied in the work. Pulsations of fluid flow at the pump outlet were determined using the impedance method, the method of load variation, and special bench systems.Results. The paper implemented a technique for determining the dynamic characteristics of a gear pump in the drive shaft speed range of 500-2500 rpm for four harmonic components of the vibration spectrum in a wide range of dynamic loads (from inertial to capacitive nature). The bench systems yielding the calculation of the dynamic characteristics of the pump with a minimum error based on the condition of matching the dynamic load and the source of vibrations were analyzed. The developed approach to the evaluation of the dynamic characteristics of the pump was verified through comparing the calculated and experimental data of pressure pulsations in the bench systems with choke, cavity and an extended pipeline at the pump outlet.Discussion and Conclusions. The method for determining the dynamic characteristics of a volumetric pump was implemented using special bench systems developed by the authors. The research results show that the gear pump under study can be considered as an independent source of flow fluctuations, for which the deviation of its own dynamic characteristics from the average values does not exceed 10% for the first harmonic component.

Published: July 2022

The advent of technology has opened the frontiers of education, especially with the introduction of electronic learning (e-learning) in the field of pedagogy. However, many institutions are still emerging in e-learning deployment and are faced with complex challenges despite the existing potential for the effective development of e-learning. This current study seeks to explore the strengths, weaknesses, opportunities, and threats (SWOT) to integrating e-learning for teaching purposes from the perspective of the academic staff of the University of Cape Coast (UCC), Ghana. The study adopted a cross-sectional survey in which 102 teaching staff from UCC participated. Among the major perceived threats and weaknesses reported were; lack of capacities in terms of institutional facilities, academic staff competencies, fluctuation of internet connectivity, and inadequacy of computers. The strengths and opportunities of integrating e-learning in this context were reported in the participants understanding of the potential of e-learning in teaching and their willingness to undergo training for this purpose. The findings of the study reveal that transforming teaching and learning through e-learning innovations beyond rhetoric requires systematic efforts at the teacher and institutional levels as well as other stakeholders.
Speech Act Analysis of Amador Daguio’s The Wedding Dance
Authors: Serdeña Jerry A. 
Published: July 2022

The study of meaning behind word and sentence levels is the core of discourse analysis. It burrows beneath the surface of conversation exchanges between characters in a literary piece. Doing so draws the readers to the context of the story. Hence, this paper attempted to exhaustively analyze a short story titled Wedding Dance written by a Filipino poet and novelist, Amador Daguio. To comprehensively scrutinize the meat of the utterances as the linguistic data in the analysis process, the researcher utilized Searle’s five (5) speech act categories. The findings of the study showed that the conversation exchanges between the main characters, Awiyao and Lumnay, are abundant in terms of directives, commissives, representatives, declarations or performatives, and expressives.

¿Cómo se aprende a escribir una tesis doctoral?
Authors: Perez Camila 
Published: July 2022

Durante el año 2017 hice trabajo de campo en una cárcel de la Provincia de Buenos Aires gestionada por el Servicio Penitenciario Bonaerense. Allí me propuse documentar etnográficamente una experiencia de alfabetización llevada adelante entre personas privadas de su libertad, es decir que: tanto los alfabetizadores como los y las estudiantes se encontraban presos. Realicé esta investigación con una beca de cinco años, otorgada por el CONICET para llevar adelante mi formación doctoral.
Si ya el proceso de inmersión y permanencia en el campo (carcelario) había resultado complejo y hostil, la reconstrucción de lo vivido me generó nuevas incomodidades y contradicciones. Para poder sortearlas y avanzar intenté múltiples estrategias con diversos resultados. En este artículo me interesa reconstruir mis aciertos y fracasos desde un ejercicio autoetnográfico y reflexivo que busca recuperar los aprendizajes significativos transitados.

Published: July 2022

Durante el año 1986, en Villa Mercedes, ocurrió uno de los mayores conflictos sindicales de la historia reciente de la Provincia de San Luis, protagonizado por trabajadores y trabajadoras de la empresa Alimentaria San Luis. En él, se pusieron en juego distintos reclamos y estrategias, involucrando un intercambio de experiencias entre dos generaciones distintas. La invisibilización del conflicto por parte de los medios de comunicación, obligó a articular esas experiencias y utilizar otros canales de información. Asimismo, en la construcción del pasado que realizan los ex trabajadores y trabajadoras se elabora una crítica sobre el discurso y accionar de los medios de comunicación en ese contexto.
En este artículo se propone una periodización del conflicto, para luego abordar un análisis a través de las fuentes orales sobre el papel desempeñado por los medios de comunicación, y las distintas alternativas construidas por los trabajadores y trabajadoras para informarse y visibilizar su accionar en el resto de la sociedad mercedina.

Published: July 2022

Este trabajo analiza las desigualdades digitales de género en relación a la tecnología entre estudiantes de nivel medio de escuelas de gestión pública de la Ciudad Autónoma de Buenos Aires en el período 2018 – 2020.
La primera distinción entre varones y mujeres que se observó en el trabajo de campo se dio a partir de la apropiación de consolas de videojuegos, y a partir de los juegos divididos en juegos para nenas y para nenes. A partir de la exclusión de las mujeres del mundo de los videojuegos se generan desigualdades en la autopercepción del saber en torno a la tecnología y en la posibilidad de participar del campo digital.
Estas desigualdades son rastreadas en la presente investigación bajo una metodología mixta, a partir una encuesta propia y entrevistas en profundidad.

Abstract
The demand for medicinal plants and their derived substances is increasing day by day due to their relevance in the context of drug discovery and development. The goal of this investigation is to assess the pharmacological and phytochemical potentials of the grossly underexplored Antidesma montanum Blume (Family: Phyllanthaceae). The methanolic extract of the leave of this plant was fractionated and then followed by initial screening of phytochemical. The investigation of the pharmacological potential, which includes antioxidant, antidiarrheal, anti-inflammatory, analgesic, anti-pyretic, and anxiolytic evaluations, was accomplished using an in vitro free radical scavenging assay with 2,2-diphenyl-1-picrylhydrazyl (DPPH), castor oil-induced diarrheal test, egg albumin test, acetic acid-induced writhing model, brewer’s yeast induced fever test, swing test, open field, and light-dark test, respectively. The investigation o phytochemicals proposes that the methanol extract of A. montanum possesses flavonoids, tannins, terpenoids, saponins, amino acids, fixed oils, and sterols. Pharmacological evaluation suggests that A. montanum possesses significant antioxidant, anti-diarrheal, anti-inflammatory, and analgesic effects. The methanol and chloroform fractions exhibited better DPPH radical scavenging activities with an IC50: 103 ± 0.05 and 108.7 ± 0.05 µg/ml, respectively. The methanol and chloroform fractions also showed anti-inflammatory capacities in the egg albumin (IC50 values: 89.10 ± 0.07 and 92.85 ± 0.07 µg/ml, respectively) model. The plant also showed anti-pyretic and anxiolytic activities in a dose-dependent manner. One of the possible sources of phytotherapeutic lead compounds is A. montanum. To extract and analyze the key bioactive components of this essential therapeutic plant, more research is required.
Reading Symbols in Japanese Garden
Authors: Gyori Peter , Fekete Albert 
Published: July 2022

Abstract
Creating a Japanese garden raises a number of methodological questions. The form of these gardens are well known, but their religious symbols are not well researched in English literature. The aim of the research is to introduce and interpret the religious symbols and references present in Japanese gardens, to categorize their appearance by taking into account their unique characteristics, their role in the garden, contributing to a deeper understanding and the understanding of the form-shaping approach. The gardens presented by this study are closely related to the practice of the religious community that creates or maintains them. The garden elements do not only serve an aesthetic purpose, but with their spatial presence they constantly refer to religious teachings or attitudes for those who are able to read them.
A Quick, Simple, Sensitive and Selective LC-MS/MS Method Used for the Screening of Ethephon, Glyphosate and Aminomethylphosphonic Acid from Water and Food Samples
Authors: Farczádi Lénárd , Moldovan Horațiu , Duca Radu Corneliu , Imre Silvia 
Published: July 2022

Abstract
Pesticide use has increased steadily over the years in both industrial farming and local agriculture. One of the most widely used pesticides at a global level, glyphosate, has been controversial for many years and many studies have focused on the effects of this compound on human health. Ethephon is also a controversial ripening agent used to ripen crops more quickly. A basic but crucial step in the study of the effects of their use on human health is the development of adequate analytical methodologies for the quantification of the compounds in relevant samples. For this study a quick, simple and selective method which uses LC-MS/MS was developed for the determination of ethephon, glyphosate and AMPA. The method uses selective fragment monitoring for each analyte and the internal standard, without prior analytical separation. Mobile phase used consisted of aqueous ammonium formate and methanol in isocratic elution and the sample cleanup was made using solid phase extraction (SPE). The method was validated with regards to selectivity, sensitivity, accuracy and precision in accordance with applicable guidelines. After validation the LC-MS/MS method was successfully used to determine ethephon, glyphosate and AMPA residues in ground and surface water, as well as vegetable samples.
ELABELA as a Marker of Gestational Complications – A Review
Authors: Sibiak Rafal 
Published: July 2022

Abstract
Adipose tissue secretes dozens of biologically active molecules known as adipokines or adipocytokines. Apelin receptor early endogenous ligand (ELABELA, also known as ELA or APELA) is a circulating signaling protein expressed in placental tissue that binds to apelin receptors. The first animal experimental findings suggested that the ELABELA deficiency might be responsible for the pathogenesis of preeclampsia--like symptoms, i.e., hypertension and proteinuria in mice. Exogenous ELABELA supplementation reverted preeclampsia symptoms and normalized fetal birth weight in mice. Several in vitro studies confirmed that ELABELA supplementation could improve trophoblast cell functions such as invasiveness and proliferation capacity. Thus, the ELABELA axis could serve as the target of innovative therapies for gestational complications. Nonetheless, most human studies do not support the thesis that disturbances in ELABELA secretion in early pregnancy are associated with an increased risk of preeclampsia. Therefore, it is unlikely that ELABELA could serve as a novel early marker of preeclampsia in humans. Alterations in the ELABELA secretion have also been discovered among patients with other gestational complications such as GDM and fetal growth restriction.
The Influence of L-Methionine, DL-Methionine, and a Methionine Hydroxy Analog on Proliferation and Differentiation Potential of Avian Myoblasts

Published: July 2022

Abstract
Methionine is an essential amino critical to many cell functions including the synthesis of proteins. Supplementation of methionine in vivo is typically through L-methionine, DL-methionine, or a methionine hydroxy analog (MHA). The goal of this study was to compare the function of L-methionine, DL-methionine, and an MHA as a source of methionine to myoblasts in vitro. Avian myoblasts isolated from turkey embryos were plated in media containing varying concentrations of DL-methionine (DLM; 1.125 mg/mL or 0.56 mg/mL) or methionine hydroxy analog (MHA; 1.28 mg/mL or 0.64 mg/mL) as well as a methionine deficient negative control group and an L-methionine supplemented positive control group. The results of the proliferation assay exhibited cell division in the absence of methionine which was not significantly different than the positive control group. Results from the myoblast fusion assay revealed significantly greater myotube diameter between methionine supplemented groups compared to the methionine deficient negative control. The findings of this study show an ability for avian myoblasts to proliferate in the absence of methionine, the significance of which is discussed. Additionally, findings from the fusion assay suggest that DL-methionine and MHA are potential cost-effective substitutes for methionine supplementation during terminal differentiation of avian myoblasts.
