Authors: Marzuki Ismail , Asaf Ruzkiah , Athirah Admi
Published: April 2023

Heavy metals, mercury, and nickel are toxic contaminants, forming positive ions when concentrated and dissolved, and can accumulate in a specific object, including water. The activity and performance of bacterial bioremediation against toxic heavy metals vary due to bacterial characteristics and internal contaminant factors. This research aims to analyze the activity, performance, and efficiency of bioremediation of nickel and mercury pollutants using marine sponge symbiont bacteria. The bioremediation analysis procedure, suspension of bacteria Alcaligenes faecalis strain Cu4-1 (AF), and Acinetobacter calcoaceticus strain PHCDB14 (AC) interacted with heavy metal pollutants as contaminants for 15 days. Bioremediation performance and efficiency were measured using AAS. The analysis parameters consisted of the performance, efficiency, and mechanism of bacterial bioremediation against nickel and mercury pollutants. The research results show that the bioremediation performance of AF and AC bacteria can carry out the bioremediation function against Ni+2 and Hg+2 contaminants. The bioremediation performance of AF bacteria against Ni+2 pollutant is, on average 167.64Â±0.9 mg/L, equivalent to 66.85% bioremediation efficiency, and against Hg+2 an average 171.55Â±0.7 equivalent to the efficiency of 65.47%. The performance of bioremediation of AC bacteria on Ni+2 pollutant was 168.92Â±0.7 or efficiency reached 66.97%, and 145.87Â±0.8 for Hg+2, equivalent to 58.35% efficiency. The bioremediation performance of AF Ë‚ AC bacteria against Ni+2 pollutants, but against Hg+2 pollutants, the bioremediation performance of AF Ëƒ AC bacteria. The symbiotic bacteria of marine sponges are thought to have bioremediation performance against toxic metal pollutants are bacteria isolated from sponges whose body surface is covered with mucus substances.

Published: April 2023

It has been proposed that Niemann-Pick C1 like-1 (NPC1L1) is an intermediate membrane protein that facilitates cholesterol absorption at enterocytes, yet it is still being unknown mechanism. The study aimed to evaluate the pharmacokinetics of anti-cholesterol in traditional spices and investigate the interactions between anti-cholesterol compounds and NPC1L1. This research analyzed binding pocket, Admet, drug-likeness, the interactions, and binding affinities by DoGSiteScorer and Depth, AdmetSAR tools, and MOE.2009 software, respectively. The interactions and binding affinities were determined by molecular docking between NPC1L1 and 18 ligands derived from spices such as Cinnamon, Bay leaf, coriander, Garlic, Red Onion, Tumeric, Indosenian Chilli Pepper. Inhibitors were docked with NPC1L1 (PDB ID: 3QNT), and a comparison was made between the results of Ezetimibe, a prescribed NPC1L1 inhibitor. The Lipinski Rule of Five aids in identifying drug-like compounds and those that are not. As an octanolâ€“water partition coefficient log P not greater than 5, all ligand including Ezetimibe has a higher affinity for the aqueous phase. 11 out of 18 inhibitors were well absorbed and distributed by forecasting oral bioavailability. Quercetin, Curcumin, and 6-Gingerol from onion, turmeric, and ginger are the potential to inhibit cholesterol absorption in the small intestine. These three highest binding energy ligands (-14.0320 to -12.3998 kcal/mol) had high binding affinities as Ezetimibe (-15.5075 kcal/mol). High binding affinities of Ezetimibe and these ligands interact at almost in the exact locations of the N-terminal domain. Through Ser_102 of N-terminal domain NPC1L1 binding with the ligands, we suggest that traditional spices of three ligands could interfere with cholesterol absorption at the early stages.

Published: April 2023

Weather classification has become a significant challenge due to the unpredictable nature of climate conditions. For farmers, predicting the start of the rainy season is very important. This is because it is related to the cost factor that must be incurred, and also, the waiting time for the harvest will have an effect if the weather is not supportive. Farmers also have to prepare seeds for the start of their farming. Therefore, farmers who start nurseries early in the rainy season will miss significant planting time. Based on these problems, this study uses a convolutional neural network (CNN) for weather classification using cloud imagery. CNN is shown to classify different spectro-temporal features of sound and is thus suitable for cloud image classification. We collect cloud image data using secondary data. Our model will use a layer based on the convolution CNN architecture with a pooling layer and a solid layer as the output layer. The cloud dataset used is 1230 data divided into five classes, namely cloudy, foggy, rain, shine, and sunrise, which we use to train our model in research for the feature extraction process using DenseNet and VGG19. We use two types of classification, namely fully connected and Global Average Pooling (GAP). Our model can achieve a classification accuracy of 90.8% DenseNet-Fully Connected from our training process. From our testing process, our model can reach 95.7% using DenseNet-Fully Connected classification accuracy. Thus, the CNN model proved very accurate in classifying cloud images.
Textual Means of Spreading Reformation Ideas in the Society of England in the Middle of the 16th Century
Authors: Gavrilov Sergey N. , Krivorotova Alexandra A.
Published: May 2023

The death of Henry VIII in January 1547 entailed a departure from a rather rigid line in religious policy, which, in turn, led to a freer dissemination of ideas in the field of religion. This spread was characterized not only by the increased number of published texts, but also by the boldness of the authors' statements, the brightness of the images they used. The article is devoted to the study of textual means of spreading of reformation ideas in the society of England in the middle of the 16th century. The object of the study is genrediverse works: the sermon “About the plow”, written by Hugh Latimer, one of the leaders of the promotion of religious transformations in England, and the satirical work “Doctor Double Ale”, published by the London doctor Luke Shepherd. Sermons and satirical works of the middle of the 16th century, given the rather large literacy of the population of the foggy Albion, should have found a warm response from those to whom the writings were addressed. However, despite the fact that these works were created in line with the official policy of religious transformations, it is quite difficult to talk about the degree of their direct influence on its implementation.

Este artigo propõe uma técnica para estimação da matriz de impedância de rede vista por um inversor trifásico conectado à rede elétrica. Ela é baseada na injeção de perturbações binárias pseudo-aleatórias de corrente impostas pelo controle do inversor. As perturbações são injetadas nos referenciais dq sincronizados por uma malha de captura de fase (PLL), referente ao sistema de controle (CPLL). Utilizase outro PLL, exclusivamente para a estimação da matriz de impedância síncrona dq (EPLL). Por meio de análises no domínio da frequência, verifica-se que a estimação da impedância é afetada para frequências na banda passante (BP) do EPLL. Consequentemente, a BP deve ser projetada dentro de uma faixa de frequências menor do que aquelas de interesse para a estimação da matriz de impedância. O presente trabalho também aplica o critério generalizado de Nyquist (CGN) para avaliar a estabilidade do sistema. Conclui-se que a seleção equivocada da banda do EPLL pode levar a avaliações incorretas. Além disso, a banda do CPLL pode ser usada para produzir uma matriz de impedância do inversor que assegure maiores margens de estabilidade ao sistema. As discussões apresentadas neste artigo são apoiadas por simulações no software Simulink e por realizações dos controles em tempo real através de uma plataforma Typhoon.
Post-Traumatic Stress Disorder After Natural Disasters: A Review
Authors: SÖNMEZ Doğancan , HOCAOGLU Cicek
Published: April 2023

Natural disasters, which are considered as one of the most important problems of recent times, affecting all humanity, have become a public health problem. Disasters have effects on both individuals and society in different dimensions, including health, economic, social, and psychological, and can have serious negative consequences. The number of individuals affected by natural disasters is increasing every year. While it is clear that natural disasters threaten human life and bodily health, little attention has been paid to their effects on mental health. Natural disasters threaten our psychological well-being in many ways, cause both short-term and long-term psychological distress and create a significant psychological burden. Post-traumatic stress disorder (PTSD) is a syndrome that occurs as a result of a serious threat or physical injury, a near-death experience, war-related trauma, sexual assault, interpersonal conflicts, child abuse, or a medical illness. When the literature is examined comprehensively, it has been determined that the incidence of PTSD after natural disasters is quite high. Causes of post-disaster PTSD include the nature of the trauma, its severity, loss of relatives and/or property, poor coping skills, displacement, and direct exposure to disaster. Studies have shown that both non-pharmacological and pharmacological treatments are effective on PTSD.

The multidimensionality of the concept of health and the complexity of its practical application purposes of determining the health status of the population leads to talk about the process estimates and not measurements. Measurement is a much more exact and precise procedure for which not yet we have the appropriate instrument, unless we use synthetic or composite ones measures of health represented by numerical scales. The approach to measuring health depends on the approach to health. According to the traditional the concept of population health is measured based on how sick people are, how much they use health service and how many die. Today, research efforts are increasingly focused on the direction finding indicators for measuring the global state of health, which include both components i health and disease. The aim of the article is to present the situation in the Republic of Serbia through health indicators and to make recommendations for improvement.

Published: April 2023

In order to comply with the trends of sustainable, and environmentally friendly agriculture, we've been implementing various new practices. As we aim to familiarize students with these practices, we tend to integrate various sustainable projects into our agricultural curriculum. The following article introduces the potentiality of growing leafy vegetables in a floating hydroponic system, in which we've held a demonstration of sustainable food production for our students and teaching staff. The purpose of the experiment, which took place in the research greenhouse at the BC Naklo Laboratory Field from May 10 to October 12, 2020, was to analyze how different cultivation systems (classical soil and floating hydroponic system) affect the crop's characteristics and the quality of the chicory (Cychorium intybus L.). Standard agricultural practices were adopted uniformly according to crop requirements. Samplings of three radicchio varieties ('Verona', 'Monivip', and 'Anivip') have been grown on 84-cell seed plates filled with Gramoflor substrate for vegetables. When the plants attained technological maturity, we've randomly examined a few of them and therefore we could confirm that, in terms of morphological characteristics and marketable crop, the floating system is a better option in comparison to the soil cultivation system. The plants with the highest mass of the head in the floating system were the plants of the Monivip variety (482.6 g) and of the Anivip variety (468.8 g), while the plants of the Verona variety, grown in the soil cultivation, had the lowest mass of the head (258.6 g). Rapid tests have shown that the production system does not affect the internal quality of the crops.

The development of artificial intelligence, the growing power of computers and large amounts of data have had a significant impact on the possibilities for increasing the added value of data. Statistical data processing methods have been joined by machine learning methods and data visualization methods in various fields. In addition to numerical data, there are other forms, such as text, image, sound, etc. Until recently, data analytics dominated, which enabled the discovery of connections in data. In 2022, however, we were surprised by the generative use of large amounts of text, image and music data. Systems such as: GPT, DALL-E, RIFFUSION and others allow us to respond to our text requests with their compositions, images or music. With the available methods, the contents hidden in the data have become accessible to people in new ways. Despite everything, we must be aware that we evaluate the added value of the results obtained from the data with our knowledge and judgments. We are doing things we have never done before. Here we can find out that the data alone is not enough. So, what are they missing? It is necessary to add a "human" side to the data. It is mental interpretation to achieve knowledge, understanding and creative solutions. We will also look at modern "machine" data processing in an ambivalent light, i.e., in the light of dilemmas and some slips.

Mexico is the main producer and exporter of avocado (Persea americana) in the world; however, pests and diseases are limiting factors for production. One of the diseases of great economic importance is avocado scab, which is characterized by causing corky-looking lesions on the epicarp of the fruits, which decreases quality and price by up to 60%. In this study, a sampling was carried out aimed at avocado fruits with damage in the epicarp with a corky appearance, these commonly known in the field as “scab” and “purple spot”. For molecular and phylogenetic identification, a combination of techniques with morphological keys and molecular markers (ITS1/ ITS4, ITS5/ITS4, FE-1α/EF-1α, Sph1 F/Sph1R) was used. Pathogenicity tests were also carried out on fruits in plants of Hass, Flor de María and Méndez varieties. Through morphological analysis, fungi of the genera Colletotrichum, Pestalotiopsis and Elsinoe were identified. Molecular identification and phylogenetic analysis confirmed the presence of the species Colletotrichum gloeosporioides and Elsinoe perseae. C. gloeosporioides reproduced symptoms similar to the avocado scab disease. With the strain identified as E. perseae, the symptom known in the field as purple spot was confirmed, while Pestalotiopsis sp. caused descending necrosis.

Published: April 2023

During the years 2017 and 2018, leaves and stems with dark brown lesions containing hypophilic telia surrounded by chlorotic halos were collected from Sphaeralcea angustifolia plants located in Axapusco, State of Mexico. Based on the morphological characteristics, the fungus Puccinia sherardiana was identified. Uredinal stage was not detected during the observation period. Verification of the identity of the fungus was carried out by means of a phylogenetic analysis with part of a sequence of the 28S gene of ribosomal DNA. Pathogenicity tests were performed on S. angustifolia plants by inoculating teliospores. The inoculated plants developed symptoms and signs 15 days after inoculation, beginning with the presence of eruptive aecia in the epidermis of the host and later the formation of telia, completing Koch’s Postulates. The fungus P. sherardiana was previously described as a rust with a microcyclic life cycle on species of the genera Alcea, Malvastrum, Sidalcea and Sphaeralcea, belonging to the Malvaceae family; however, in this study the pathogen behaved differently. P. sherardiana will continue to be studied to determine if its life cycle is demicyclic in Mexico.

The decline and death of palms (Phoenix canariensis) in Mexico City is a problem that has increased in the last five years, causing the death of more than 500 palms and others with different degrees of damage. The causal agent has not been determined, so the present study aimed to identify the associated fungi of the decline and death of palms (Phoenix canariensis) in Mexico City. From February to August 2022, samples of symptomatic plant tissue from the trunk, petiole, rachis, and leaflets were collected at nine representative sampling sites in seven Boroughs of Mexico City. A total of 144 fungal isolates were obtained, comprising 11 different species. The species with the highest frequency were: Nalanthamala vermoesenii, Lasiodiplodia sp., Neopestalotiopsis sp., and Serenomyces sp., present mainly on the petiole and rachis; and Alternaria alternata and Phoma glomerata in the leaflets, these species have been reported as causative agents of different diseases in other countries and are reported for the first time in Mexico associated with P. canariensis. The information generated will allow establishing management measures tending to reduce the death of palms.

Pervivencia y cambios de las reducciones en la región de Huamanga, siglo XVII
Authors: Mizota Nozomi
Published: May 2023

En 2010 se realizó un viaje de estudio en la parte serrana del departamento de Ayacucho hacia el sur de la ciudad de Ayacucho (llamada Huamanga en la época colonial), y se observó que todavía existen varios pueblos cuyos nombres se encuentran en las «Relaciones geográficas de Indias» que datan de 15868, los cuales sin duda conservan hasta hoy el estilo de la reducción con una plaza mayor en su centro, rodeada de una iglesia y algunas construcciones administrativas, etcétera (Figura 1). Además, recogiendo informaciones fragmentarias obtenidas en los documentos coloniales, se hallan reducciones, que aunque no permanecían o funcionaban como esperaban los gobernadores o autoridades coloniales, tenían aspectos de que, adaptándose a los cambios a través del tiempo y a las situaciones locales, llegaron a integrarse de alguna manera en la sociedad indígena. Por lo tanto, sería sencillamente precipitado concluir que la reducción fue un proyecto fracasado en la sociedad colonial. En este artículo quisiéramos examinar si son apropiados tales discursos sobre la reducción, tal como han venido siendo aceptados y asentados hasta el momento en la historiografía actual. A través de un estudio de caso, se analizará el estado y el cambio de las reducciones que experimentó la región de Huamanga, después de la reducción toledana, especialmente durante el siglo XVII (Figura 2).

La corrupción y el desarrollo económico del Perú contemporáneo
Authors: Quiroz Alfonso W.
Published: May 2023

Mi estudio sobre la historia de la corrupción en el Perú1 es un intento de reinterpretación de la realidad del país, que tiene como eje el tema de la corrupción y su lucha a lo largo de los años. No es solo un estudio de los lados negativos de la historia del Perú; también analiza sus lados positivos, luminosos, como la influencia en la lucha contra la corrupción de importantes —aunque poco conocidos o entendidos— líderes e intelectuales en el pasado. Pero, al mismo tiempo, examina la formación de la conciencia de la corrupción entre los peruanos de todas las generaciones. Por ello, es importante subrayar dichas contribuciones. Aprendí muchísimo releyendo lo escrito sobre el tema hace décadas y siglos atrás: con esta lectura, me he dado cuenta de cuán serios e importantes fueron sus esfuerzos para reformar las instituciones de nuestro país y, por tanto, aunque algunos de ellos no dieron resultados prácticos o fueron olvidados prontamente, sí quedaron en la memoria colectiva. Muchos recordarán, por ejemplo, a Manuel Gonzáles Prada y su importante desafío a la corrupción de su época, que es tan paradigmática en nuestra historia y forma de concebir el país.
Effects of Liriope platyphylla and Organic Acids in Hanwoo Feed on Greenhouse Gas Reduction
Authors: Ha Jae-Jung , Won Seunggun
Published: May 2023

Background: Liriope platyphylla and organic acids (humic and fulvic acids) as additives in the feedstock may aid in decreasing CH4 formation in the rumen. Based on previous studies, Hanwoo steers were raised with feedstock added with Liriope platyphylla and organic acids and their fecal samples were analyzed to determine the changes in their organic matter and nitrogen content determining the GHG emissions from feces in the form of CH4 and N2O. Methods: Ten Hanwoo cattle were provided with experimental diet and their weights were measured to determine harmful effects of experimental diet and measure fecal composition. To measure CH4 emission from the rumen in vitro, rumen fluid with Liriope platyphylla 1.0% and organic acids 0.05% added to the feed was prepared and incubated in triplicate. Result: The addition of Liriope platyphylla had a positive effect on immune function and blood composition, as well as CH4 reduction and further the addition of organic acids resulted in the lowering of CH4 emissions when compared with that of the control. The addition of Liriope platyphylla and organic acids is a potential additive of reducing CH4 emissions from ruminants without disrupting cattle growth.

Published: May 2023

Background: Wheat is a cereal crop that is widely farmed across the world and ranks first in global crop production. Wheat cultivation is the world’s most important food crop.The assessment of genetic divergence existing in the germplasm collections is very important to select genetically divergent parents for hybridization in a transgressive breeding programme for development of high yielding wheat varieties coupled with quality, multiple resistance and wider adaptability. Methods: The experiment on 21genotypes including two checks viz., HD 2967 and PBW 824 was conducted to work out the genetic variability, heritability, genetic advance and divergence analysis for yield and yield contributing traits in wheat (Triticum aestivum L.). The experiment was laid out in randomised block design (RBD) during Rabi, 2021-2022 at Lovely Professional University, Phagwara, Punjab. Result: The analysis of variance revealed mean sum of square due to genotypes were significant for all the characters indicating sufficient genetic variability among the genotypes. The magnitude of PCV and GCV were moderate for grain yield per plant and harvesting index, which suggests greater phenotypic and genotypic variance among the genotypes and responsiveness of the attributes for making further improvement by selection and indicating limited scope for improvement. High heritability coupled with high genetic advance observed for harvest-index thus these characters show additive gene action in their expression. In divergence analysis, maximum intra-cluster distance exhibited by cluster 2 followed by cluster 1among the different genotypes. The maximum inter-cluster distance between cluster 2 and 3 followed by cluster 2 and 7 and the minimum inter cluster distance was recorded between cluster 5 and 6 followed by cluster 1 and 3. It indicated that for crop improvement in wheat diversified genotypes may be selected from cluster 2 and cluster 3 to received maximum transgressive recombinants from segregating generations.
Analyzing Financial Risk and Profitability in the UAE Banking Sector
Authors: Ibrahim Mukdad
Published: April 2023

The paper examines four main sources of financial risk exposure for four banks in the United Arab Emirates during the years 2003 to 2009. It begins by measuring stability levels for different types of financial risks using the coefficient of variation measure. The research then proceeds to investigate the nature of the relationship between financial risk and the actual reported financial performance of each company, namely the return on equity and return on assets. The findings show that all four sources of financial risk showed significant stability while both profitability indicators exhibited significant instability over the same period. Moreover, performance on the return on assets indicator was strongly and positively tied to a company’s return on equity indicator across the four banks but exhibited little or no interconnection with the four types of risks that banks are commonly exposed.

Published: April 2023

Com o objetivo de tecer um contradiscurso ao discurso teológico hegemônico que, privilegiando a interlocução com a filosofia ocidental, é racista e patriarcal, apresentamos, ainda de modo seminal, o quefazer teológico na interlocução com o pensamento negro, a filosofia africana e, de modo especial, o mulherismo africana. O método da pesquisa está marcado pela análise bibliográfica e a descrição da experiência de encontrar-se na Igreja das Santas Pretas. Os resultados desta pesquisa, como todo pensamento, são inacabados. Desejamos apresentar à comunidade acadêmica algumas referências da filosofia africana como possível interlocutora da teologia, para que esta possa superar a cumplicidade e dependência da filosofia ocidental e, consequentemente, do racismo e do patriarcado. Também desejamos colocar os processos de resistências e reexistências das mulheres negras no centro da reflexão teológica e demonstrar que eles fazem parte de uma memória ancestral que informa o ser afrodiaspórico. A teoria do mulherismo africana pode ser um instrumental útil, também para a teologia, para interpretar esses processos e, com isso, sinalizar outros caminhos para nossas relações de gênero.

Published: April 2023

La necesidad de resignificar los fundamentos del quehacer teológico constituye una labor impostergable, para garantizar que la Buena Noticia que se anuncia pueda iluminar las nuevas sensibilidades culturales y las coyunturas históricas de inicios de siglo y milenio. Desde la triada historia-oikonomía-teología, el desarrollo expositivo recoge los diferentes paradigmas desde donde se ha buscado avanzar en la comprensión del misterio trinitario, dando prelación al paradigma relacional. Desde este paradigma, se realiza una aproximación a las implicaciones de entender a la Trinidad en clave relacional de comunión de amor, en lo relativo a la experiencia mística, que está a la base de la vida cristiana, la vida de la Iglesia y la teología. Se argumenta que la resignificación de la comprensión del misterio trinitario en clave relacional de comunión de amor contribuye en el plano de la mística cristiana a que todo creyente pueda reconocer, en la propia vida, la presencia y la posibilidad de la comunión divina.

Authors: Wardani Andini Dwi , Munir Ahmad
Published: April 2023

The advancement of technology has a significant impact on teaching English nowadays. One of the tools that can quickly provide access to language learning is a mobile device. Moreover, the rising use of mobile devices or Mobile Assisted Language Learning (MALL) has been closely linked to the role of EFL teachers. Hence, this study aimed to investigate teachers' perspectives towards using the "Lets View" application for elementary students in the EFL classroom. The study was conducted by implementing a qualitative method. The instrument used in this study was questionnaires and interviews. The subject of this study was six English elementary school teachers who teach using the LV application in a private school in Surabaya. The results showed that using the new learning media, such as the LV application in EFL classrooms, is very useful for teachers. It is due to that this application can use mobile phones or iPad as the second portable blackboard for teaching reading, writing, and vocabulary and giving quizzes for beginner-level students. The researchers also revealed four obstacles EFL teachers face when implementing the LV application: internet connection, time limitation, lack of teachers' competence, and lack of student's English skills. Besides, several ways to increase students' learning engagement include allowing students to raise their hands, playing the game on the application, and guessing English vocabulary by giving pictures that appeared on it. To sum up, teachers viewed the LV application as suitable media for learning English at school.

The aim of the work was to obtain and characterize hybridomas producing monoclonal antibodies to antigens of coronavirus SARS‑CoV‑2, promising for the construction of diagnostic immunochemical tests. Materials and methods. Recombinant nucleocapsid and receptor binding fragment of spike protein of SARS‑CoV‑2 were used for immunization of BALB/c mice. Antigens were absorbed on aluminium hydroxide gel and injected subcutaneously to BALB/c mice at a 7-day-interval. Immune splenocytes and myeloma cells SP2/0-Ag14 were fused by polyethylene glycol 1450. Cell cultures producing specific antibodies against nucleocapsid and receptor binding fragment were selected applying indirect ELISA in 96-well plates sensitized by desired antigens. Clones of hybridomas were obtained using the method of limiting dilutions. Production properties were studied through in vitro cultivation in 24-well culture plates. Immune-ascitic fluids were collected during the cultivation of hybrid cells in peritoneal cavities of BALB/c mice. Monoclonal antibodies were purified by affinity chromatography on protein A sepharose sorbent, conjugated with horseradish peroxidase, and tested for the possibility to be used in sandwich ELISA for detection of inactivated SARS‑CoV‑2 coronavirus strain “Isolate B”. Results and discussion. As a result of hybridization and selection of clones, hybridomas producing monoclonal antibodies to nucleocapsid and receptor binding fragment of SARS‑CoV‑2 have been obtained. During the in vitro and in vivo cultivation the clones maintained the consistent proliferative and antibody producing activity. The application of monoclonal antibody 415D12 as a capture one and 411D12 antibody conjugated with horseradish peroxidase as a detector antibody in ELISA allows for identifying SARS‑CoV‑2 coronavirus at a minimum concentration of 1·103 PFU per ml.

Published: May 2023

Bacterial ghosts are intact walls of bacterial cells that are relieved of their contents through pores formed by mild biological or chemical methods. Methodology for generating bacterial ghosts increases the safety of killed vaccines while maintaining their antigenicity through milder preparation procedures. Moreover, bacterial ghosts can simultaneously carry several antigens or plasmid DNAs encoding protein epitopes. In recent years, there has been a growing interest in the development of prototype vaccines and systems for delivery of biologically active substances based on bacterial ghosts. This review discusses the progress in the development of this type of medications over the last years. Various methods of obtaining bacterial ghosts, their advantages and limitations are considered. The phage-mediated lysis of bacteria, molecular manipulations with lysis genes, difficulties encountered in scaling the biotechnological production of bacterial ghosts, and ways to overcome them are described in detail. The use of bacterial ghosts as alternative killed vaccines, adjuvants, recombinant antigenic platform, carrier of plasmid DNA by the models of pathogens of particularly dangerous infections of bacterial etiology is investigated.

Nipah virus (Nipah virus, NiV) is a representative of the genus Henipavirus of the Paramyxoviridae family, the causative agent of a dangerous infectious disease with a wide range of clinical manifestations – from an asymptomatic (subclinical) form to severe encephalitis with fatal outcome. Despite the fact that the disease caused by this virus is registered only in the countries of Southeast Asia, the possibility of importing the pathogen to non-endemic territories is not excluded. Also, this pathogen is able to infect not only a large number of people, but also animals, causing serious diseases and significant economic damage, posing both, a medical and veterinary problem. This review presents the data available in the modern press on the structure and classification of the Nipah virus, possible cycles of its transmission, spread, methods of indication and identification in clinical and biological material, as well as the effectiveness of their use depending on the timing of the onset of the disease and available commercial diagnostic and preventive drugs.
