Use of Waste Plastic Char as Adsorbent for Removal of Arsenic and COD from Aqueous Solution
Authors: DUTTA NEELANJAN , Gupta Anirban
Published: January 2022

In present study, the solid char derived from the pyrolysis of waste high-density polyethylene (HDPE) and polypropylene (PP) was tested for removal (adsorption) of inorganic arsenic (As5+) and organic matters (COD) from water and wastewater, respectively. It was observed that the solid char could remove 60% of arsenic (+5) at a dose of 4 gm/L for a contact time of 30 min and the COD removal was 50% at a dose of 4 gm/L with a contact time of 25 min. In both cases the adsorption data was found to fit better with Langmuir model. The adsorption capacity of mixed plastic char for As5+ was observed to be in the range of 1.45 – 1.75 mg/gm and in the range of 60.625-67.9 mg/gm for COD. Proximate and ultimate analysis indicated that the pyrolytic char had a large quantity of volatile matter (46.50-48.0%), carbon (41.3–84.7%), and a small amount of moisture (1.2-2.5%). The calorific value and density of plastic char were found to be in the range of 13.50-17.50 MJ/kg and 1.55 - 1.60 gm/m3. FTIR spectra of mixed HDPE and PP waste pyrolytic oil showed the presence of mostly alkanes and alkenes. It was found that with the increase of pyrolysis temperature, the pore size of solid char increased. The XRD pattern of the plastic chars obtained in this study showed sharp diffraction crystalline peaks. The plastic char can be used for further research for removal of other contaminants from aqueous solution.

Published: January 2022

The emergence of exceptional points (EPs) in the parameter space of a (2D) eigenvalue problem is studied in a general sense in mathematical physics. In coupled systems, it gives rise to unique physical phenomena upon which novel approaches for the development of seminal types of highly sensitive sensors shall leverage their fascinating properties. Here, we demonstrate at room temperature the emergence of EPs in coupled spintronic nanoscale oscillators, coming along with the observation of amplitude death of self-oscillations and other complex dynamics. The main experimental features are properly described by the linearized theory of coupled system dynamics we develop. Interestingly, these spintronic nanoscale oscillators are deployment-ready in different applicational technologies, such as field, current or rotation sensors, radiofrequeny and wireless devices and, more recently, novel neuromorphic hardware solutions. Their unique and versatile properties, notably their large nonlinear behavior open up unprecedented perspectives in experiments as well as in theory on the physics of exceptional points. Furthermore, the exploitation of EPs in spintronics devises a new paradigm for ultrasensitive nanoscale sensors and the implementation of complex dynamics in the framework of non-conventional computing.

Stability Analysis and Flutter Suppression of Ultrasonic Elliptical Vibration Milling of Ti-6Al-4V Alloy
Authors: Zhang Yuemin , Wang Xiaobo , Niu Ying , Zhao Bo
Published: January 2022

Ti-6Al-4V alloy is typical aircraft materials to be difficult machined. Ultrasonic elliptical vibration-assisted milling has been proved to greatly enhance machining performance. In ultrasonic elliptical vibration milling(UEVM), the cutting edge moves in 3D space, reducing extrusion friction between the flank and machined surface, and playing an important role in high precision-efficient manufacturing of difficult-to-cut materials. This paper focused on the stability analysis and flutter supression of ultrasonic elliptical vibration milling of Ti-6Al-4V alloy. There are separated and unseparated types of ultrasonic elliptical vibration milling systems, which stability is analyzed in this study by simulating their tool tip motion paths. The essence of the tip and workpiece at high-frequency separation is revealed through analysis of cutter tooth path in UEVM. Next, the coordinate method is used to set up the window function to facilitate the derivation of true instantaneous chip thickness. The dynamic model of UEVM is established to study the system stability and plot its stability prediction lobes diagrams. The effect of machining parameters on the system stability is assessed and discussed in detail. The prediction results show that the stability region and axial depth of cut grow with the increase of feed rate per tooth and decrease of ultrasonic frequency. Among the six groups of ultrasonic amplitude parameters studied, the optimal system's stability corresponds to the ultrasonic amplitudes of 5 and 3μm in the x-and y-directions, respectively. Finally, stability tests of UEVM are performed, which results well match the numerical simulation predictions. This implies that the proposed window function is adequate, the theoretical model is valid, and the predicted stability curve is feasible and reliable.
Visualizing Omicron: COVID-19 Deaths vs. Cases Over Time
Authors: Arnaout Ramy , Arnaout Rima
Published: January 2022

For most of the COVID-19 pandemic, the daily focus has been on the number of cases, and secondarily, deaths. The most recent wave is caused by the omicron variant, first identified at the end of 2021 and the dominant variant through the first part of 2022. South Africa, one of the first countries to experience and report data regarding omicron, reported far fewer deaths, even as the number of reported cases rapidly eclipsed previous peaks. However, as more countries report on omicron, there remains uncertainty as to how it compares to prior waves. To more readily visualize the dynamics of cases and deaths, it is natural to plot deaths per million against cases per million. Unlike the time-series plots of cases or deaths that have become daily features of news outlets during the pandemic, which have time as the x-axis, in a plot of deaths vs. cases, time is implicit, and is indicated in relation to the starting point. Here we present and briefly examine such plots from a number of countries and from the world as a whole, illustrating how they summarize features of the pandemic in ways that are harder to extract from time series. These plots suggest that in most places, the omicron wave is very different from those that came before. Code for generating these plots for any country is provided on GitHub (https://github.com/rarnaout/Covidcycles).
Fluctuations of the planetary gravitational field and nonlinear interactions with matter – triggering earthquakes.
Authors: Nitsche Michael
Published: January 2022

AbstractThe orbits of the big planets are very stable during millions of years. In addition to this, there is another important circumstance: the orbits of the planets lie almost on the same level. They represent natural oscillators on a big scale. Such a rhythm or such duration of vibration is determined by the time period from conjunction to conjunction of two planets. These are relatively stable frequencies. A non-linear correlation function forms a good way of describing these processes. It can be shown that this correlation function can also be interpreted as a non-linear interaction of the planetary fluctuations of the gravitational field with material structures. The vibrations of the planetary gravitational field lead to higher vibrations, to higher harmonics, in material structures. The problems of the correlation function are the coefficients ak and the meaning of Hij. In my researches I restricted myself to the polar qualities which are associated with the concepts of "stability" and "instability". The change from stable to unstable conditions and vice versa, can be observed in the evolution of many complex systems. Statistical researches will be presented and show this non-linear influence.

Published: January 2022

The present study focuses on synthesizing Cu-bismuth oxide (CuBi2O4) based nanorods by using a simple co-precipitation method for the photocatalytic degradation of caffeic acid (CA). Incorporating Cu metal ions during the synthesis of CuBi2O4 nanorods might be advantageous to avoid aggregation and control the leach out of metal ions. The calculated bandgap values of ~ 1.04, 1.02, and 0.94 eV were observed for CuBi2O4 with different amounts of Cu 1.0, 0.50, and 0.25 g, respectively. Varying quantities of Cu metal ions easily tuned the bandgap value within the CuBi2O4 based nanorods. However, a further decrease in the bandgap value increased the recombination rate; less photocatalyst performance was observed. The Cu within the CuBi2O4 based nanorods changed the electronic properties as well as the antibacterial ability. Therefore, the synthesized CuBi2O4 based nanorods cluster might be a promising material for the photocatalytic degradation of CA.

Published: January 2022

Background
Most antiepileptic drug therapies are symptomatic and adversely suppress normal brain function by nonspecific inhibition of neuronal activity. In recent times, growing evidence has suggested that neuroinflammation triggered by epileptic seizures might be involved in the pathogenesis of epilepsy. Although the potential effectiveness of anti-inflammatory treatment for curing epilepsy has been extensively discussed, the limited quantitative data regarding spatiotemporal characteristics of neuroinflammation after epileptic seizures makes it difficult to be realized. We quantitatively analyzed the spatiotemporal changes in neuroinflammation in the early phase after status epilepticus in rats, using translocator protein (TSPO) positron emission tomography (PET) imaging, which has been widely used for the quantitative evaluation of neuroinflammation in several animal models of CNS disease.
Methods
The second-generation TSPO PET probe, [18F]DPA-714, was used for brain-wide quantitative analysis of neuroinflammation in the brains of rats, when the status epilepticus was induced by subcutaneous injection of kainic acid (KA, 15 mg/kg) into those rats. A series of [18F]DPA-714 PET scans were performed at 1, 3, 7, and 15 days after status epilepticus, and the corresponding histological changes, including activation of microglia and astrocytes, were confirmed by immunohistochemistry.
Results
Apparent accumulation of [18F]DPA-714 was observed in several KA-induced epileptogenic regions, such as the amygdala, piriform cortex, ventral hippocampus, mediodorsal thalamus, and cortical regions 3 days after status epilepticus, and was reversibly displaced by unlabeled PK11195 (1 mg/kg). Consecutive [18F]DPA-714 PET scans revealed that accumulation of [18F]DPA-714 was focused in the KA-induced epileptogenic regions from 3 days after status epilepticus and was further maintained in the amygdala and piriform cortex until 7 days after status epilepticus. Immunohistochemical analysis revealed that activated microglia but not reactive astrocytes, were correlated with [18F]DPA-714 accumulation in the KA-induced epileptogenic regions for at least 1 week after status epilepticus.
Conclusions
These results indicate that the early spatiotemporal characteristics of neuroinflammation quantitatively evaluated by [18F]DPA-714 PET imaging provides valuable evidence for developing new anti-inflammatory therapies for epilepsy. The predominant activation of microglia around epileptogenic regions in the early phase after status epilepticus could be a crucial therapeutic target for curing epilepsy.
Vom Reizthema zum Qualitätsmerkmal – Die Coronapandemie als Gamechanger frühkindlicher Medienerziehung?
Authors: Lienau Theresa , Frense Elena
Published: January 2022

Während des ersten Covid-19-bedingten Lockdowns wurden die Rufe nach einer umfassenden Digitalisierung von Bildungsinstitutionen laut. Die Vermittlung von dafür notwendigen frühkindlichen Medienkompetenzen ist jedoch noch lange nicht im Alltag von Kitas angekommen. Es stellt sich die Frage, inwieweit die Extremsituation, in der sich Kitas und Familien während des ersten Lockdowns befanden, einen Gamechanger darstellt: Konnten die ausgelösten Digitalisierungsprozesse Eltern und Fachkräfte für die Potenziale digitaler Medien in der Kita sensibilisieren? Und inwieweit konnten Fachkräfte im Umgang mit digitalen Medien Hemmungen abbauen und Kompetenzen stärken? In der vorgestellten mehrstufigen Mixed-Methods-Studie wurden zwischen März und Dezember 2020 in zehn Kindertagesstätten sowohl Eltern als auch Fachkräfte befragt. Die Ergebnisse zeigen, dass es durch den ersten Lockdown in den befragten Kitas diverse Anstösse hin zu einer offeneren und positiveren Grundhaltung gegenüber digitalen Medien gab. Etablierte analoge Praktiken wurden in vielen Bereichen aufgebrochen oder überdacht und stärker digitalisiert. Seitens der Eltern lassen sich – trotz einer Zunahme der kindlichen Mediennutzung im ersten Lockdown – keine wesentlichen Haltungsveränderungen hinsichtlich der Notwendigkeit einer gezielten Medienerziehung beobachten. Die Ergebnisse deuten darauf hin, dass die positiven Erfahrungen, die Kitas mit digitalen Medien gemacht haben, ein notwendiger erster Schritt zu einer nachhaltigen Verankerung von Medienpädagogik, jedoch keineswegs ein ‹Selbstläufer› sind.

From the great variety of methods to improve the efficiency of cutting tools, it is necessary to highlight the methods of applying wear-resistant coatings, which in recent years are increasingly used. Applying wear-resistant coatings on the cutting tool can significantly increase its efficiency and intensify machining modes. Mechanisms of strengthening the wear-resistant coating for materials have been analyzed under the impact of technological parameters of coating condensation process on its structure parameters and mechanical properties, formation of single and multi-element coatings based on titanium nitrides, aluminum, and silicon, the transformation of coating properties by obtaining complex coatings, and principles formation of complex coatings designed for different cutting tools. The influence of the coating on the mechanical properties of high-speed steel is shown. In the magnetron sputtering coatings on P6M5 steel samples, the microhardness of the coatings is TiN – 20–24 GPa, AlN – up to 16 GPa, TiAlN – up to 35 GPa, AlTiN – up to 32 GPa, TiAlSiN – 32–37 GPa, including while the microhardness of the substrate of steel P6M5 – 6–9 GPa. The microhardness of TiAlN and TiAlSiN coatings applied on an instrumental basis is 1,5 – 1,9 times higher than the microhardness of TiN, AlN coatings. It was found that the wear intensity of P6M5 steel without coating is 6 times higher than with AlTiN, TiAlN, and TiAlSiN coating, 3 times higher than with TiN and AlN coating. The coated tool is characterized by increased reliability and higher stability and allows the processing process with higher cutting modes.

Authors: Bencsik Andrea , Csinger Bence
Published: January 2022

The study on technostress is very significant in today's knowledge-based society. Technostress, which has developed due to the information-technology explosion over the past decade, plays an increasingly critical role in people’s lives. The study shows that the flood of information and the increased use of more technological tools could cause frustration, anxiety, and fear. The timeliness of the topic lies in the fact that if society does not pay attention to this new kind of public disease now, it would have a negative impact on people's health, quality of life, and efficiency at the corporate level. The study's theoretical background was analyzed by reviewing the international scientific literature available on the subject of technostress. The research aims to explore the relationship between factors belonging to the group of technostress creators concerning Hungarian higher educational institutions. In the study, the authors set up a research model to explore the relationship between technostress creators, which was examined using a quantitative questionnaire query. The study covered 237 employees working in higher education in Hungary. The results were analyzed in the SPSS 22 statistical program. During the evaluation, linear regression analysis was used to explore these relationships. The results demonstrated that the five components of technostress are techno-overload, techno-invasion, techno-complexity, techno-insecurity, and techno-uncertainty. These frequently interact with each other in higher education. The results of the study point to the fact that the five components of technostress embodied in higher education institutions are interrelated, which, when appearing in the lives of university lecturers, contributes to the increase in the level of technostress. The research results could be useful for all higher education institutions in terms of what factors they should place great emphasis on to reduce or prevent technostress.

Authors: Koyluoglu Selcuk , Dogan Mesut
Published: January 2022

Innovation efforts aim to attain important competitiveness by improving performance criteria. It has led to very strong ties between innovation and performance, which is also accepted by the recent business understanding. The purpose of the current study, which is designed in compliance with this understanding, is to examine the effect of innovation strategies on business performance in enterprises using high technology. Innovation strategies consist of 6 dimensions: proactive strategy, risk-oriented strategy, defensive strategy, future-oriented strategy, offensive strategy, and analytical strategy. Business performance was measured as product performance, employee-based performance, customer-based performance, financial performance, and process performance. The study involved the innovation strategies and business performance scale developed by Morgan and Strong (1998), Chandy and Tellis (1998), and Eskici (2020). The current study conducted a survey on 346 managers of companies operating in Turkey and using high technology. The obtained data were analyzed with the help of JAMOVI and SPSS 26.0 programs. Exploratory factor analysis, confirmatory factor analysis, Pearson correlation, and regression analysis methods were used in empirical analysis. The result determined that innovation strategies are effective on business performance. In other words, future-oriented strategy is effective on the product, customer-based, employee-based, financial, and process performances of enterprises. On the other hand, it was determined that future-oriented strategy and risk-oriented strategy are not effective on enterprises' product, customer-based, employee-based, financial, and process performances. In addition, offensive, analytical, defensive, proactive, and risk-oriented strategies are ineffective in process performance. Analytical, defensive, future-oriented, and proactive strategies are effective on product performance, customer-based performance, and financial performance of businesses. As a result, it was determined that innovation strategies affect customer-based performance (R2=0.687) and financial performance (R2=0.701) of companies more.
Is a New Asian Monetary Fund Emerging?
Authors: Bhowmik Dr. Debesh
Published: January 2022

The plan initiated by Japan for forming an Asian Monetary Fund in a mode of ASEAN+3 countries after Asian financial crisis in 1997 was not realised due to opposition from USA, IMF and China and the plan was revamped through CMI multilateral currency swap and pacific nation’s joining with US Dollar hegemony but at present it is confronting Chinese supremacy over the region. Thus, in this paper the author thought of forming a new Asian bloc consisting of SAARC, ASEAN, GCC, China, Japan and Korea for which a new framework of Asian Monetary Fund can be set up with a view to not only supplying additional liquidity in crisis period as well as for developmental finance but also can function for issuing a common currency of the new Asian bloc that is a currency basket which will be formed by currencies of China, Japan and Korea and the currencies of blocs viz SAARC, ASEAN and GCC where unit of account of currency will be measured by gold or silver and the exchange of currency unit of Asia is primarily fixed with Chinese Yuan. The exchange rates of all currencies in the basket will be calculated daily through floating exchange rate mechanism in Asian bloc and common currency will also be floated in SDR basket if CUA is included in SDR basket. The exchange rates will be maintained by Asian Monetary Fund through target zone of ±2.5% fluctuation. The plan also requires monetary and trade integration as well as political integration with the implementation of Asian stock exchange institute, Asian Parliament, Asian Security council, Asian Central Bank and Asian Clearing Union respectively. The common barriers like Sino-Japan rivalry, US dollar hegemony, non-cooperation from IMF, premature OCA criteria and low capital market internationalisation may delay the process of Asian Economic Integration towards formation of a new Asian Monetary Fund.

Authors: Shankar Kumar Ravi , Krishnan M. , Kumar Praduman , Narayan G. Badri , Prakash Swadesh , Kranthi Kumar Dhande
Published: January 2022

Fast population growth, increase in per capita income and increase in level of awareness among the people regarding health are the main causes of increase in demand for nutritional and protein rich food. Fish is very good source of protein as well as vitamins. Fish may play a vital role to ensure the nutritional security in rural areas. Fish production and consumption has however undergone major uneven changes in the past four decades. It is found that at higher ends of the income distribution, the consumption of milk, eggs, meat, fish and processed foods have risen. Present study focuses on the demand for fish in Delhi and NCR in comparison to other items like chicken, mutton and eggs. A Three Stage Budgeting Framework of demand is used for present analysis. NSSO data of household consumption has been used for analysis. Per capita consumption of “fish”, “chicken” and “mutton” in Delhi and NCR were estimated and it was found to be 4.04 kg/ annum, 2.27 kg/annum and 0.81 kg/annum respectively. So, per capita consumption of “fish” was found to be greater than “chicken” as well as “mutton”. Income elasticity of demand was estimated for each income group of population and in most of the cases demand for fish was found to be income elastic. Compensated as well as non-compensated price elasticity of demand for fish was also estimated. It was found that price elasticity of fish was almost unitary elastic whereas price elasticity of chicken” and mutton were price inelastic. Fish demand was also projected up to 2020 and it was found to be 5.11 kg/capita/ annum in 2020. With increase in income of the population as well as awareness of health benefit of fish, it is expected that fish consumption will increase at a very fast rate in future. However the presence of a large proportion of vegetarian population in Delhi and NCR is a challenging proposition for increasing of overall fish consumption of Delhi and NCR.
Edentulous ridge space closure after bone augmentation using different graft materials: A report of two cases
Authors: Lin Shih-Ying , Sun Teresa Chanting , Chou Chia-Hsuan , Hsu Li-Fang
Published: January 2022

Post-extraction alveolar ridge resorption is a common sequela when missing mandibular molar spaces are not managed in a timely fashion. The situation becomes more complicated in patients who seek orthodontic treatment if closure of the edentulous space is the major objective in order to avoid prosthetic rehabilitation. In the present article, two cases are reported, in which different bone augmentation graft materials were used and treatment duration and post-orthodontic alveolar ridge characteristics were compared. A regional acceleratory phenomenon after the grafting procedure facilitated uneventful orthodontic space closure. The status of the investing alveolar bone was compared using post-treatment cone-beam computed tomography. Both autogenous bone graft and allograft ridge augmentation procedures aided in successful molar protraction through the resorbed mandibular alveolar ridge, as well as preventing periodontal attachment loss.

In August - September 2020, during cruise 49 of the R/V Akademik Nikolay Strakhov , comprehensive geological, geophysical, hydroacoustic, geomorphological and hydrophysical research studies of the western segment of the Arctic zone within the Pechora and Kara Seas began in 2018-2019 were continued. As previously, the work was aimed at mapping the relief and modern sediments in order to assess the possible negative consequences of changes in natural conditions on the Arctic coast of the Russian Federation. The main purpose of the research was to assess the evolution of natural environments within the southwestern part of the Kara Sea shelf in connection with the observed global climate change in the Arctic, as well as with the expected increase in anthropogenic load on the Arctic shelf due to the development of oil and combustible natural gas fields. Bottom grab and a shock ground tube were used to obtain samples of recent sediments of the Kara Sea. The sampling sites were determined based on the analysis of data from bathymetric bottom survey and continuous seismic profiling. During the research, the boundaries of the distribution of various facies of bottom sediments within the southwestern part of the Kara Sea shelf have been clarified. The main feature of the modern bottom sediments in the southwestern part of the Kara Sea shelf is a wide areal distribution of thin facies - pelitic muds. Along the eastern and southern coasts of the Archipelago Novaya Zemlya, a distribution zone of iceberg sediments with a width of at least 150 km has been established. The formation of icebergs should be associated with the movement of the Novaya Zemlya cover glacier, formed 30-20 thousand years ago during the Sartan Ice Age. As the studies have shown, the general Holocene transgression in the Kara Sea was periodically replaced by short regressions, at least in the southwestern part of the basin.

REPRESENTATIONS OF IRONY IN ARTISTIC TEXT
Authors:   Astrakhan State University, KUZNETSOVA E.V.
Published: January 2022

The interpretation of irony in works of art, as well as the disclosure of the mechanism of its action, are not without difficulties. Irony is often quite difficult to understand, especially in the works of fiction by foreign writers. The question of the context necessary for the functioning and implementation of irony also remains unresolved. Obviously, an ironic message can be localized in one word at the lexical level, but there is no single answer to the question of whether it can be read in the context of the entire work. This raises the problem of interpreting the context of irony.
TRANSFORMATION PROCESSES OF THE POST-SOVIET PERIOD IN KABARDINO-CHERKESS PROSE
Authors:   Institute for the Humanities Research, BETUGANOVA E.N.
Published: January 2022

The article identifies transformation processes in the Kabardino-Circassian literature, which is a poorly studied and promising phenomenon under the conditions of a transitional period. The processes of the post-Soviet period that took place in Russian society contributed to the manifestation of the crisis in all areas of the humanities in general and in literary criticism in particular. This period can also be characterized as the emergence of a certain methodological freedom, which makes it possible to look for new cognitive means for such a literary problem as “man and time”. An attempt is made in the work to study the artistic realization of the aforementioned problem in the conditions of the post-Soviet era.

The article gives an assessment of water resources for water supply in the Novosibirsk region. The geological and hydrological characteristics of the territory under consideration have been studied, surface and underground water supply sources have been considered. Studies have shown that there is not enough water from the rivers to meet the needs of cities, therefore, it is necessary to provide for other sources of water supply. Accordingly, the analysis of the chemical composition of groundwater, which can be used for household and drinking purposes, after additional processing, has been carried out. The article presents the characteristics of the state of operating wells, the analysis of which shows that their service life depends on a number of natural and technical factors that manifest themselves with varying degrees of intensity. To provide the population with drinking water of the required quality, methods of desalination of water extracted from wells have been proposed.

Objetivo: Avaliar a sensibilidade e a viabilidade econômica do sistema de confinamento utilizado para a engorda de bovinos tomando como referência uma propriedade localizada no norte do estado de São Paulo, Brasil.

Metodologia: Utilizou-se a abordagem multidimensional para avaliar a sensibilidade, o resultado econômico foi analisado através do fluxo de caixa sendo o valor presente líquido (VPL) o indicador de viabilidade, os riscos foram incorporados com a simulação de Monte Carlo para os preços de alimentação, aquisição e venda dos animais que foram as variáveis aleatórias discretas, já a medida de valor foi o VPL, calculado com a taxa mínima de atratividade de 7,55% ao semestre e as probabilidades foram estimadas pela frequência relativa.

Resultados: A probabilidade de o confinamento ser uma atividade atrativa economicamente foi de 30,2%, consequentemente o sistema foi inviável em 69,8%. No âmbito da sensibilidade, o confinamento foi mais vulnerável à oscilações no preço de venda, o aumento de 1% no valor do boi gordo gerou o acréscimo de 46% no VPL, sendo seguido pelo preço de reposição, o aumento de 1% no valor do boi magro levou a uma redução de 29% no VPL, e pelo preço da alimentação, o aumento de 1% no valor da tonelada de matéria seca diminuiu o VPL em 12%.

Contribuições do Estudo: Os resultados encontrados nesta pesquisa poderão subsidiar novas avaliações em amostras representativas, incorporar os estudos sobre essa temática e auxiliar os tomadores de decisão.

The dramatically increasing levels of antibiotic resistance are being seen worldwide and are a significant threat to public health. Antibiotic and drug resistance is seen in various bacterial species. Antibiotic resistance is associated with increased morbidity and mortality and increased treatment costs. Antisense-related technologies include oligonucleotides that interfere with gene transcription and expression; these oligonucleotides can help treat antibiotic-resistant bacteria. The important oligonucleotides include Peptide Nucleic Acids (PNAs), Phosphorodiamidate Morpholino Oligomers (PPMOs), and Locked Nucleic Acids (LNAs). Typically, the size of these structures (oligonucleotides) is 10 to 20 bases. PNAs, PPMOs, and LNAs are highlighted in this review as targets for genes that cause the gene to be destroyed and impede bacterial growth. These results open a new perspective for therapeutic intervention. Future studies need to examine different aspects of antisense agents, such as the safety, toxicity, and pharmacokinetic properties of antisense agents in clinical treatment.
An Updated Review on the Role of Single Nucleotide Polymorphisms in
COVID-19 Disease Severity: A Global Aspect
Authors: Lee Ping-Chin , Ng Jun Wei , Chong Eric Tzyy Jiann
Published: January 2022

Coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syn-drome coronavirus 2 (SARS-CoV-2) and recently has become a serious global pandemic. Age, gender, and comorbidities are known to be common risk factors for severe COVID-19 but are not enough to fully explain the magnitude of their effect on the risk of severity of the disease. Single nucleotide polymorphisms (SNPs) in several genes have been reported as a genetic factor contrib-uting to COVID-19 severity. This comprehensive review focuses on the association between SNPs in four important genes and COVID-19 severity in a global aspect. We discuss a total of 39 SNPs in this review: five SNPs in the ABO gene, nine SNPs in the angiotensin-converting enzyme 2 (ACE2) gene, 19 SNPs in the transmembrane protease serine 2 (TMPRSS2) gene, and six SNPs in the toll-like receptor 7 (TLR7) gene. These SNPs data could assist in monitoring an individual’s risk of severe COVID-19 disease, and therefore personalized management and pharmaceutical treatment could be planned in COVID-19 patients.

Background:

miR-210, a key hypoxamiR, regulates hypoxia and
inflammation-linked hypoxia. Systemic lupus erythematosus (SLE), a chronic
autoimmune disease, is responsible for many pathological disorders, including
photosensitivity.

Objective:

This study aimed to find the correlation between circulating miR-210/HIF-1α
levels and photosensitivity in SLE patients and other SLE-associated pathological
complications in a single-center case-control study.

Methods:

The study population comprised 104 SLE Egyptian patients with
photosensitivity, 32 SLE patients without photosensitivity, and 32 healthy subjects. SLE
activity was assessed for all patients using the SLE Disease Activity Index (SLEDAI).
Clinical complications/manifestations and hematological/serological analyses were
recorded. HIF-α concentration was investigated by ELISA, and miR-210 expression was
analyzed by qRT-PCR.

Results:

The results revealed that circulating miR-210 was significantly increased in the
SLE/photosensitivity group versus the SLE and control groups. The additional
occurrence of malar rash, oral ulcers, renal disorders, or hypertension resulted in a
higher expression of miR-210. SLEDAI activity status showed no effect on miR-210.
Erythrocyte sedimentation rate, white blood cells, hemoglobin, platelets, patient age, and
disease duration were positively correlated with circulatory miR-210. HIF-α concentration
was significantly induced in the SLE/photosensitivity group versus the SLE and control
groups. In SLE/photosensitivity, the presence of renal disorders and hypertension
resulted in the highest HIF-α concentrations. A strong positive correlation was recorded
between HIF-α concentration and circulatory miR-210 in SLE/photosensitivity patients (r
= 0.886).

Conclusion::

The dysregulation of circulating miR-210/HIF-1α levels in SLE/
photosensitivity patients is controlled by the presence of additional pathological
complications, and results suggest that the hypoxia pathway might interact positively
with the pathogenesis and disease progression of SLE.
