Authors: Wang Shui-Hua , Satapathy Suresh Chandra , Anderson Donovan , Chen Shi-Xin , Zhang Yu-Dong 
Published: August 2021

Aim: Coronavirus disease 2019 (COVID-19) is a form of disease triggered by a new strain of coronavirus. This paper proposes a novel model termed “deep fractional max pooling neural network (DFMPNN)” to diagnose COVID-19 more efficiently.Methods: This 12-layer DFMPNN replaces max pooling (MP) and average pooling (AP) in ordinary neural networks with the help of a novel pooling method called “fractional max-pooling” (FMP). In addition, multiple-way data augmentation (DA) is employed to reduce overfitting. Model averaging (MA) is used to reduce randomness.Results: We ran our algorithm on a four-category dataset that contained COVID-19, community-acquired pneumonia, secondary pulmonary tuberculosis (SPT), and healthy control (HC). The 10 runs on the test set show that the micro-averaged F1 (MAF) score of our DFMPNN is 95.88%.Discussions: This proposed DFMPNN is superior to 10 state-of-the-art models. Besides, FMP outperforms traditional MP, AP, and L2-norm pooling (L2P).

Published: August 2021

Background: Destroyed lung can cause mediastinal displacement and asymmetric chest deformity. Reports on bilateral lung transplantation (LT) to treat destroyed lung and asymmetric chest deformity are rare. This study presents our surgical experience of bilateral LT among patients with destroyed lung and asymmetric chest deformity.Methods: Six patients with destroyed lung and asymmetric chest deformity who underwent bilateral LT at our center from 2005 to 2020 were included in the study. Demographic data, technical data, perioperative details, and short-term follow-up data were reviewed.Results: Three patients underwent bilateral LT via anterolateral incisions in the lateral position without sternal transection, while three patients underwent bilateral LT via clam-shell incisions in the supine position with sternal transection. Only one patient required intraoperative extracorporeal membrane oxygenation. Four patients underwent size-reduced LT. In the other two patients, we restored the mediastinum by releasing mediastinal adhesions to ensure maximal preservation of the donor lung function. Patients in the lateral position group had a higher volume of blood loss, longer operation time, and longer postoperative in-hospital stay than those in the supine position group. However, these differences were not statistically significant. Postoperative computed tomography in the supine position group revealed that the donor lungs were well expanded and the mediastina were in their original positions.Conclusions: Although bilateral LT in patients with destroyed lung and asymmetric chest deformity is high risk, with sufficient preoperative preparation and evaluation, it is safe and feasible to perform bilateral LT for selected patients. For patients without severe chest adhesions, releasing the mediastinal adhesions and restoring the mediastinum through a clam-shell incision in the supine position is a simple and effective method to maximally preserve the donor lung function without pneumonectomy or lobectomy.

Published: August 2021

Background: Border disease is believed to be one of the most important diseases in the animal husbandry industry, which has not yet been eradicated in Iran. The development of approaches based on the application of interfering RNA (RNAi) for antiviral therapy has attracted a great deal of attention over the recent years. The present research was conducted to design, construct, and apply shRNA against the NS3 gene of BDV to evaluate the prevention of BDV proliferation in the cell culture system. For this purpose, the suitable oligonucleotide sequence of NS3 gene coding was selected utilizing BDV- X818 strain. Afterwards, using shRNA design software, shRNA molecules were designed and synthesized. These shRNAs were cloned into the desired vectors and were finally transfected in HEK293T cells employing the third generation of lentiviral packaging system. Subsequently, these shRNA expressing lentiviruses were transduced to the MDBK cell line to challenge to border virus. In order to evaluate the efficacy of shRNAs, the viral infectious titer and RNA copy number were calculated with TCID50 and Real-time RT-PCR tests, respectively.Results: The results revealed that shRNAs 1, 2, and 3 decreased viral RNA by more than 90% compared to the control groups. BDV titer noticeably decreased after the challenge with shRNAs 1, 2, and 3 from ~88% up to 99% in comparison with the control groups.Conclusions: Overall, it could be concluded that RNAi may be considered as a strong treatment proposal against viruses, such as BDV.

Published: August 2021

Los estudios socioculturales constituyen un campo del saber interdisciplinario que han generado nuevas teorías y procesos renovados de elaboración social de las ciencias de la salud. Objetivos. En el contexto de la COVID-19, permitieron conocer, comprender e interpretar los fundamentos, significados y vivencias del personal de primer nivel de atención en salud. Método. Se empleó investigación biográfico-narrativa, como técnicas se usó las entrevistas, análisis de contenido y triangulación, los instrumentos que se utilizaron: fueron la ficha de registro documental, batería de preguntas y matrices de análisis de categorías deductivas. Resultados. Para la presentación de los resultados y su posterior discusión, se usaron figuras tales como: nubes de palabras, tablas de resumen y redes semánticas diseñadas con el apoyo del programa ATLAS.ti; se citaron, además, múltiples comentarios expresados por los entrevistados; y, se triangularon con base en las fuentes, teorías y métodos consultados en bases académicas de alto impacto. Conclusión. Al final, se concluyó que más allá de la fundamentación teórico-metodológica imprescindible y que requiere de actualizaciones incesantes, es necesario valorar al ser humano invisibilizado tras un perfil profesional y laboral; se encontraron, asimismo, doce significados socioculturales construidos por el personal de salud: apatía, desorientación, distanciamiento, inmutabilidad, integralidad, miedo, pandemia, perfeccionamiento, religiosidad, resignación, salud y trabajo en equipo. Como palabras generadoras de las vivencias narradas, se hallaron ocho: catarsis, familia, humanidad, incertidumbre, virtualidad, vulnerabilidad, espiritualidad y conflicto existencial.
Crónica de un artista-investigador-docente.

Published: August 2021

Este artículo rescata una serie de experiencias que se han presentado a lo largo del semestre que corre de agosto a diciembre de 2020, año que nos ha dejado marcados por la pandemia del covid y cuyas consecuencias aún estamos lejos de evaluar. He recurrido al recurso de la narración como una forma idónea de presentar los hechos y las reflexiones que los acompañan puesto que, ante todo, ha sido desde el territorio de la literatura que hace ya muchos años me he introducido al mundo del arte y a la reflexión científica. La narración revive el día a día de la impartición de clases por medio de plataformas digitales, a la vez que discute las posibilidades de la investigación artística como generadora de conocimiento, así como la legitimación de ese conocimiento entre las comunidades de discurso tanto de las ciencias como de las artes.

Abstract
This article rescues a series of experiences that have been presented throughout the semester that runs from August to December 2020, a year that has left us marked by the covid pandemic and whose consequences we are still far from evaluating. I have resorted to the resource of narration as an ideal way of presenting the facts and the reflections that accompany them since, above all, it has been from the territory of literature that many years ago I have been introduced to the world of art and scientific reflection. In the narration, the day-to-day teaching of classes through digital platforms is revived, while the possibilities of artistic research as a generator of knowledge are discussed, as well as the legitimation of that knowledge among the communities discourse both of the sciences as of the arts.
Investigación en el entorno de la pandemia: un ejercicio de reflexión
Authors: De Gunther Delgado Leonel , Valencia Ramos Arturo , Brenscheidt Gennant Jost Diana 
Published: August 2021

En este artículo se ofrece una reflexión sobre las consecuencias de la pandemia en la investigación en las humanidades y las artes. Se analiza como un fenómeno complejo, es decir, tejido en conjunto con otros datos, hechos o fenómenos, cuyas características visibles lo colocan como un fenómeno que no hemos pensado bien, sin nombre conocido, fuera de las disciplinas y sin normas conocidas, cuyo abordaje requiere algo más que la sola cognición disciplinada. Seguimos para su desarrollo una estrategia dialéctica, como un medio de acceso al conocimiento, no lógico; sino como dispositivo epistemológico. Se analizan en forma de preguntas las bifurcaciones que derivan de las condiciones de la pandemia y ejemplificamos a partir de los estudios de performance y sociológicos, como dispositivos teóricos, una variedad de manifestaciones artísticas en línea que nos permiten preguntarnos por el surgimiento de nuevas formas de ser (fenómenos humanos o artísticos) e, incluso, de un nuevo modo de ser investigador en las humanidades y las artes.

Abstract
This paper reflects the consequences of the pandemic on research in the humanities and the arts. First, it is analyzed as a complex phenomenon woven together with other data, facts, or phenomena. Its visible characteristics place it as a phenomenon that we have not thought of well, without a known name, outside disciplines, and without known norms, whose approach requires more than just disciplined cognition. Second, we follow a dialectical strategy for its development, as a means of access to knowledge, not logical but as an epistemological device. Third, we analyze in the form of questions the bifurcations that derive from the conditions of the pandemic. Finally, we exemplify from performance studies and sociological ones, as theoretical devices, various artistic manifestations online. Both allow us to ask about the emergence of new ways of being (human or artistic phenomenons) and new ways of being a researcher in the humanities and the arts.
Algunas manifestaciones actuales de la música indígena en Sonora, México
Authors: Ferrales Nápoles Marybel 
Published: August 2021

La riqueza de la tradición musical indígena de Sonora estriba en su variedad y significados constituyendo un factor importante en la identidad de sus pueblos. Sin embargo, las investigaciones sobre la música de las culturas autóctonas de la región son escasas; por ello, se hace necesario un estudio enfocado a su significación como fenómeno cultural colectivo y a su análisis musical. El objetivo de este trabajo es dar a conocer como se manifiesta actualmente la música de algunas etnias del estado de Sonora mediante la trascripción y análisis de obras representativas. Se inició recogiendo las evidencias auditivas y visuales de la música indígena que ha llegado a nuestros días como producto de un largo proceso histórico en diferentes etnias del Estado de Sonora. Se seleccionaron cinco obras extraídas de grabaciones propias o facilitadas por Lutisuc (2007), las cuales fueron transcritas y acompañadas con una breve descripción del contexto donde se interpretan y su análisis melódico, armónico, formal y métrico, así como los procesos de acompañamiento, entonación y timbre de voces. Se concluye que la música indígena contemporánea interpretada en el territorio sonorense es trasmisora de los pensamientos actuales de las etnias; en muchos casos, reconstruyendo parámetros antiguos para moldear las generaciones actuales y no interpretándose fuera del contexto local.
Abstract
The richness of the indigenous musical tradition in Sonora lies in the variety and meanings constituting an important factor in the identity of their towns. However, the research about the music of the native cultures on the region are only a few; therefore, it is necessary a study focusing the meaning as a collective cultural phenomenon and his musical analysis. The objective of this work is releasing information of how music is currently manifested today in some ethnic groups of Sonora through transcriptions and analysis of representatives works. It began by collecting auditory and visual evidence of indigenous music that has reached our days as a product of a historical process in different ethnic groups in the State of Sonora. Five works were selected from own recordings or provided by Lutiscu (2007), which were transcribed and accompanied with a short description of the context where they are interpreted and its melodic, harmonic, formal and metric analysis; as well as the accompaniment, intonation and timbre of voices. It concludes that contemporary indigenous music performed in the Sonoran territory it is a transmitter of the actual thoughts of the ethnic groups; in many cases, rebuilding old parameters to shape current generations and not interpreting itself outside the local context.

Published: August 2021

Repetitive enrichment of soils samples from an agricultural land and newly marked dumpsite on electrical transformer fluid yielded six bacterial species that have the capacity to utilize electrical transformer fluids (askarel) as carbon and energy source. Bacterial species namely: Micrococcus, Arthrobacter, Pseudomonas putida, Pseudomonas spp, Norcadia and Corynebacterium were identified using morphological and biochemical characteristics. The abilities of these bacterial species to utilize the electrical transformer fluids as carbon source in minimal salt medium (MSM); sub cultured in concentrations of 5, 10, 15 and 20μL of electrical transformer fluids were investigated for twentyÃ¢â‚¬Âone days period. Physiological changes in terms of biomass increase were monitored by measuring the pH and optical density of the culture medium. From the results obtained, there was observed a general decrease in the pH and increase in Optical density (O.D). The mean pH and O.D. readings ranged between (4.34Ã¢â‚¬Â6.13 and 0.073Ã¢â‚¬Â0.386) respectively. The decreased pH could justify for the acidic metabolites produced in the course of utilization of askarel as growth substrates. This study suggested that, the tropical ecosystems can provide exotic bacterial species that are capable of degrading or mineralizing polychlorinated biphenyls and their derivatives from dumpsites and agricultural soils.

Levels of some antinutrients, namely, cyanide, nitrate, and oxalate and some micronutrients including vitamin C, βÃ¢â‚¬Âcarotene (provitamin A) and some mineral elements (Fe, Mg, Cu, Zn, Ca Na and K) were determined in fresh and processed samples of Telfairia occidentalis Hook.f. as a step towards establishing processing techniques that would reduce or eliminate unacceptable levels of antinutrients and the associated health problems. The processing methods used were cooking (5 and 10 min boiling) and sun drying. There was significant (p< 0.05) reduction in the levels of these phytotoxins. The cyanide levels in the variously processed samples were: fresh sample (170.83mg/kg), 5 min decoction (36.98mg/kg), 10 min decoction (44.87mg/kg), leaves boiled for 5 min (49.88mg/kg), and leaves boiled for 10 minutes (34.68mg/kg), and sundried leaves (94.74mg/kg). Vitamin C content was significantly (p< 0.05) reduced, the levels being 192.28mg/100g, 1.51mg/100g, 2.16mg/100g, 53.70mg/100g, 35.60mg/100g and 13.15mg/100g in fresh sample, 5 min decoction, 10 min decoction, leaves boiled for 5 min, leaves boiled for 10 min, and sundried sample respectively. βÃ¢â‚¬Âcarotene content was elevated in the cooked vegetable, while its content decreased in sundried samples. However, cooking beyond 5 min led to significant (p < 0.05) reduction in βÃ¢â‚¬Â carotene levels in the vegetable. Sun drying had no significant effect on Fe, Cu, Mg, Na and K in the vegetable. Cooking however, led to decreases in the levels of these minerals. It is concluded that moderate cooking and sun drying reduced the levels of the studied antinutrients in T. occidentalis without adversely compromising the micronutrient contents.

Consequently, total 138(46.9%) out of 294 volunteers were reported to have ova of Schistosomamansoni in their urine samples. Among which, 84 (28.6%) volunteers with<50 ova in per 10 ml of urine showed light infection while remaining 54(18.4%) volunteers with >50 ova in per 10 ml of urine showed heavy infection.This difference was found statistically significant (X 2= 6.52, p > 0.05).The mean immunoglobulin status observed in their serum sample were; IgE(2141.6 ± 143.7 mg/dL), IgG (13.6 ± 3.53 mg/dL), IgA (3.72 ± 0.149 mg/dL),IgM (2.82 ± 0.48 mg/dL) and IgD (0.12 ± 0.04 mg/dL). The relationship betweenintensity of infection and serum level of IgM & IgE were positivelycorrelated (r =0.27 and r =0.65, respectively) while IgG, IgA and IgD wereshowing negative correlation with the strength of infection (r = Ã¢â‚¬Â0.65, r = Ã¢â‚¬Â0.39 and r = Ã¢â‚¬Â0.18, respectively). Therefore, IgG and IgA can be considered asmarkers of light infection and IgM and IgE for heavy infection respectively.Since, the levels of IgG, IgA and IgD were found very low in infected volunteersthan control subjects hence, are suggested to play insignificant protectiverole in schistosomic infection., a trematode is a significant parasite of human beingscausing intestinal schistosomiasis. In the present investigation, 294 volunteersfrom central India were screened for schistosomic infection, and theserum immunoglobulin (Ig) levels were calculated as an anti

Authors: Bhamre P. R. , Desai A. E. 
Published: August 2021

The purpose of this study was to assess the toxic effects of heavy metal compoundsÂ like Cadmium chloride (CdCl2) and Zinc sulphate (ZnSo4) on respiratoryÂ metabolism of the freshwater mussel Lamellidens consobrinus.The effectÂ was observed for 24, 48, 72 and 96 h exposure. On exposure of musselsÂ to toxic concentrations the respiratory metabolic rate was found profoundlyÂ decreased after two hours of intoxication in Cadmium chloride (0.0863 Â±Â 0.0032 mg/gm/l/h) and Zinc sulphate (0.1517 Â± .0018 mg/gm/l/h). The oxygenÂ consumption was continuously decreased up to 96 h in CdCl2 (0.0303 Â±Â 0.0019 mg/gm/l/h) and ZnSo4 (0.0746. Â± 0.0019 mg/gm/l/h).The decrease inÂ metabolic rate was more prominent in cadmium chloride than zinc sulphate.Â This impact may be due to inhibition of enzymatic pathways and osmoregulatoryÂ response which depends on the time of exposure to heavy metal compoundsÂ used for experimental work.
