A Two-Stage SEM–Artificial Neural Network Analysis of Integrating Ethical and Quality Requirements in Accounting Digital Technologies
Authors: Bocean Claudiu George , Vărzaru Anca Antoaneta
Published: August 2022

Digital technologies affect all areas and activities of society. Accounting is no exception to this trend, as organizational information system accounting increasingly integrates digital technologies. The paper aims to study the integration of ethical requirements with the quality requirements in implementing digital technologies based on artificial intelligence, blockchain, the internet of things, and cloud computing in financial and managerial accounting. This empirical study of 396 accountants from Romanian organizations involves investigating the influence of ethical and quality requirements of digital technologies on the perception of users’ satisfaction in financial and managerial accounting. Empirical research encompasses a quantitative approach using structural equation modeling and artificial neural network analysis in a two-stage procedure. Some of the existing ethical issues can be addressed by implementing new digital technologies but implementing these emerging technologies can generate other ethical and quality issues that accounting and IT professionals must address in a combined effort. The research results show that the ethical requirements that influence the perception of financial and managerial accounting are security and trust. Among the quality requirements, the most critical influence in the perception of accountants is reliability.
Goose Astrovirus in China: A Comprehensive Review
Authors: Zhu Qinghe , Sun Dongbo
Published: August 2022

Goose astroviruses (GoAstVs) are small non-enveloped viruses with a genome consisting of a single-stranded positive-sense RNA molecule. A novel GoAstV was identified in Shandong in 2016 and quickly spread to other provinces in China, causing gout in goslings, with a mortality rate of approximately 50%. GoAstV can also cause gout in chickens and ducks, indicating its ability to cross the species barrier. GoAstV has only been reported in China, where it has caused serious losses to the goose-breeding industry. However, in view of its cross-species transmission ability and pathogenicity in chickens and ducks, GoAstV should be a concern to poultry breeding globally. As an emerging virus, there are few research reports concerning GoAstV. This review summarizes the current state of knowledge about GoAstV, including the epidemiology, evolution analysis, detection methods, pathogenicity, pathogenesis, and potential for cross-species transmission. We also discuss future outlooks and provide recommendations. This review can serve as a valuable reference for further research on GoAstV.

Plants grow together with microbes that have both negative and positive impacts on the host, while prokaryotes are in turn also hosts for viruses, co-evolving together in a complex interrelationship. Most research focuses on the interaction of either bacterial pathogens interacting with the plant host, or the impact on viruses on their pathogenic bacterial hosts. Few studies have investigated the co-evolution of bacterial pathogens with their host plants as well as with their bacterial viruses. In this work, we aimed to identify the genes that were associated with both phage sensitivity and host pathogenicity of the bacterium Xanthomonas oryzae pv. oryzae (Xoo), which is the most important bacterial rice pathogen. Using the Tn5 transposon mutation technology, we created a library of Xoo strain C2 comprising 4524 mutants, which were subsequently tested for phage infectability. The phage infection tests showed that less than 1% of the mutants (n = 36) were resistant to phage infection, which was attributed to the Tn5 insertion in 19 genes. Interestingly, three out of 19 genes that conveyed resistance to the phage resulted in reduced pathogenicity to rice seedlings compared to the wild type. We identified three genes involved in both phage infection and bacterial virulence, which were studied by knockout mutants and complementation experiments. All of the three knockout mutants were resistant to infection by phage X2, while the complemented strains restored the susceptibility to the bacterial virus. Surprisingly, the genes are also essential for pathogenicity, which we confirmed by single knockout mutants corresponding to the Tn5 mutants. All three genes are involved in lipopolysaccharide synthesis, thus changing the cell envelope surface molecule composition. Our work shows a possible balance in terms of the connection between bacterial virulence and phage resistance, supporting the deployment of phages for the biocontrol of plant pathogens.

Herein, we present our findings of an early appearance of the Monkeypox virus in Prague, Czech Republic. A retrospective analysis of biological samples, carried out on the 28th of April, revealed a previously unrecognized case of Monkeypox virus (MPxV) infection. Subsequent data analysis confirmed that the virus strain belongs to the ongoing outbreak. Combined with clinical and epidemiological investigations, we extended the roots of the current outbreak at least back to 16th of April, 2022.
Hepatitis B Surface Antibody (Anti-HBs) Kinetics during Rituximab Chemotherapy and Performance of Hepatitis B Vaccine before Immunosuppression: Two Prospective Studies
Authors: Araujo-Neto João Marcello de , Guimarães Gabriela Sousa , Fernandes Flavia Ferreira , Soares Marcelo A.
Published: August 2022

Rituximab promotes strong immunosuppression leading to a high risk of hepatitis B reactivation (HBV-R) and chronic infection. Current recommendations on HBV-R prevention are expensive and poorly individualized. In resolved hepatitis B patients, previous studies suggest that anti-HBs titers before immunosuppression can predict HBV-R risk. However, guidelines claim that additional data are necessary before recommending spare drug prophylaxis in patients with high anti-HBs titers. On the other hand, in patients with no previous contact with HBV, guidelines recommend vaccine before immunosuppression despite minimal evidence available. To shed light on these knowledge gaps, two prospective studies were conducted to evaluate anti-HBs in hematological cancer patients treated with rituximab. In the first study, anti-HBs-positive patients were referred for following up antibody titers before and during immunosuppression. Patients with anti-HBs ≥ 100 mIU/mL before immunosuppression had no negative seroconversion (anti-HBs loss), in contrast to 18% of those with anti-HBs < 100 mIU/mL. In the second study, patients with no previous contact with HBV were invited to receive HBV vaccine before rituximab chemotherapy. None seroconverted with anti-HBs. In conclusion, both studies reinforce the need to review concepts about HBV prevention during immunosuppression on current guidelines. Narrowing the use of drug prophylaxis and improving vaccine indications are recommended.

We determined the levels of neutralizing antibodies against the SARS-CoV-2 ancestral strain, Delta and Omicron variants of concern (VOCs), in 125 healthcare workers who received CoronaVac as their primary vaccination and later received either a single ChAdOx1 or a combi-nation of two consecutive boosters using either two ChAdOx1 doses or a ChAdOx1 or BNT162b2 as the primary and second boosters, respectively, or two doses of BNT162b2. The titers 12 weeks after primary vaccination were inadequate to neutralize all strains. After a single ChAdOx1 booster, the levels of neutralization at Day 30 varied significantly, with only a small proportion of participants developing neutralizing titers against Omicron at Day 7 and 30. The two doses of ChAdOx1 as the booster induced the lowest activity. A combination ChAdOx1 and BNT162b2 induced greater neutralization than by two doses of ChAdOx1. Two doses of BNT162b2 as the booster had the maximal activity against Omicron VOC.
Freeze-Thaw Effect on Riverbank Stability
Authors: Li Chao , Yang Zhen , Shen Hung Tao , Mou Xianyou
Published: August 2022

The stability of riverbanks in cold regions is affected by the freeze-thaw action. The freeze-thaw process causes changes in the moisture content, friction angle, and cohesiveness of the bank material. Together with the freeze-thaw effect, seepage pressure influenced by the changing water levels, and the bank slope are the key factors affecting bank stability. A limit equilibrium bank stability model considering the infiltration water pressure effect is developed and applied to the Shisifenzi section of Inner Mongolia reach of the Yellow River. Laboratory tests of field samples with moisture contents of 15%, 18%, 21%, and saturated showed that the freeze-thaw action reduced the degree of saturation by 34.37 %, 30.71%, 32.48%, and 46.23%, respectively, accompanied by reductions in the internal friction angles by 1.78%, 2.74%, 6.33%, and 5.32%. These changes resulted in a 24.35% to 29.13% reduction in the safety factor of bank stability. Together with seasonal variations in the water levels the field data showed that the bank stability safety factor in the study site increases gradually through the melting period, dry period, wet period, flooding period, and low flow period. The slope stability safety factor increases with the stage of the river but decreases with the groundwater level.

Published: August 2022

Floods can be caused by heavy rainfall and the consequent overflow of rivers, causing low-lying areas to be affected. Populated regions close to riverbeds are the sectors most affected by these disasters, which requires modelling studies to generate different scenarios. The work focuses on the bibliometric analysis of the search for topics such as flood modelling focused on the research, risk, and assessment of these catastrophes, aiming to determine new trends and tools for their application in the prevention of these natural disasters. The methodology consists of: (i) search criteria and database selection, (ii) pre-processing of the selected data and software, and (iii) analysis and interpretation of the results. The results show a wide range of studies for dimensional analysis in different flood scenarios, which greatly benefit the development of flood prevention and risk strategies. In addition, this work provides insight into the different types of software and modelling for flood analysis and simulation and the various trends and applications for future modelling.
Deep Reinforcement Learning Ensemble for Detecting Anomaly in Telemetry Water Level Data
Authors: Khampuengson Thakolpat , Wang Wenjia
Published: August 2022

Water levels in rivers are measured by various devices installed mostly in remote locations along the rivers, and the collected data are then transmitted via telemetry systems to a data centre for further analysis and utilisation, including producing early warnings for risk situations. So, the data quality is essential. However, the devices in the telemetry station may malfunction and cause errors in the data, which can result in false alarms or missed true alarms. Finding these errors requires experienced humans with specialised knowledge, which is very time-consuming and also inconsistent. Thus, there is a need to develop an automated approach. In this paper, we firstly investigated the applicability of Deep Reinforcement Learning (DRL). The testing results show that whilst they are more accurate than some other machine learning models, particularly in identifying unknown anomalies, they lacked consistency. Therefore, we proposed an ensemble approach that combines DRL models to improve consistency and also accuracy. Compared with other models, including Multilayer Perceptrons (MLP) and Long Short-Term Memory (LSTM), our ensemble models are not only more accurate in most cases, but more importantly, more reliable.
Analyzing Relationships of Conductivity and Alkalinity Using Historical Datasets from Streams in Northern Alberta, Canada
Authors: Arciszewski Tim J. , Roberts David R.
Published: August 2022

Many measurements, tools, and approaches are used to identify and track the influence of human activities on the physicochemical status of streams. Commonly, chemical concentrations are utilized, but in some areas, such as downstream of coal mines, capacity indices such as specific conductivity have also been used to estimate exposure and risk. However, straightforward tools such as conductivity may not identify human influences in areas with saline groundwater inputs, diffuse exposure pathways, and few discharges of industrial wastewater. Researchers have further suggested in conductivity relative to alkalinity may also reveal human influences, but little has been done to evaluate the utility and necessity of this approach. Using data from 16 example sites in the Peace, Athabasca, and Slave Rivers in northern Alberta (but focusing on tributaries in Canada’s oil sands region) available from multiple regional, provincial, and national monitoring programs, we calculated residual conductivity and determined if it could identify the potential influence of human activity on streams in northern Alberta. To account for unequal sampling intervals within the compiled datasets, but also to include multiple covariates, we calculated residual conductivity using the Generalized Estimating Equation (GEE). The Pearson residuals of the GEEs were then plotted over time along with three smoothers (two locally weighted regressions and one General Additive Model) and a linear model to estimate temporal patterns remaining relative to known changes in human activity in the region or adjacent to the study locations. Although there are some inconsistencies in the results and large gaps in the data at some sites, many increases in residual conductivity correspond with known events in northern Alberta, including the potential influence of site preparation at oil sands mines, reductions in particulate emissions, mining, spills, petroleum coke combustion at one oil sands plant, and hydroelectric development in the Peace basin. Some differences in raw conductivity measurements over time were also indicated. Overall, these analyses suggest residual conductivity may identify broad influences of human activity and be a suitable tool for augmenting broad surveillance monitoring of water bodies alongside current approaches. However, some anomalous increases without apparent explanations were also observed suggesting changes in residual conductivity may also be well-suited for prompting additional and more detailed studies or analyses of existing data.

Stages of development of LNG production and sales
Authors:   Russian Foreign Trade Academy of Ministry of Economic Development of the Russian Federation, Moscow, Emelyanov V. V.
Published: August 2022

In 1895 Carl von Linde developed the technology for liquefying natural gas, but only in the early twentieth century commercial production of liquefied natural gas was begun. Liquefied natural gas (LNG) is natural gas, primarily methane, that has been artificially liquefi ed by cooling to minus 160 °C for easy storage or transportation. It is a liquid that is colorless and odorless. Pure LNG is not fl ammable, does not ignite or explode on its own. There are several stages of development of LNG production and sales. The fi rst stage (1917–1941) — the first LNG plant was built in the USA. In 1917, an LNG plant was built in the US. The second stage (1959–1969) was the beginning of LNG exports from the US to Europe. The third stage (1969–2020) was the development of the world LNG market. As of early 2010, there were more than 30 large-capacity plants in the world aimed at LNG exports. The fourth stage (2020-present) is the impact of the coronavirus on the world LNG market. Since 2010, global LNG exports have increased from 302.4 billion cubic meters to 487.9 billion cubic meters in 2020. LNG already accounts for more than 40 percent of global gas trade. Leading LNG exporters include Qatar, Australia, the USA, Russia, Malaysia, Nigeria, Trinidad and Tobago, Algeria and Indonesia. Russia accounts for 8 % of global LNG exports. The pandemic situation in the world has caused oil prices to fall and remain low, so suppliers with low costs or high margins are in an advantageous position. Nevertheless, several LNG projects are planned to be launched in the near future, which will allow Russia to become one of the leaders in LNG production. The article outlines the stages of development of LNG production and sales, analyzes the current state of global LNG production, and also lists various LNG projects in Russia.

Published: August 2022

The article discusses the main current trends in the development of modern university campuses and their interaction with the existing features of urban infrastructure. A design solution for a local object of accessible public space on the BSTU campus is proposed. It is able to provide conditions for both learning and social interactions, attracting and involving not only students and university staff, but also potential applicants, as well as residents of nearby areas of the city. The symbiosis of these processes leads to an increase in the public image of the university, and, as a result, the formation of a new urban center of attraction. Some tools for the implementation of team design activities of undergraduates of the department “Architectural structures” within the framework of the discipline “Project-based learning” are presented. A business model has been built reflecting the connections between market participants for the implementation of the idea, and possible development prospects based on cooperation with potential partners. The features of the external appearance of the space dictated by the surrounding architectural environment are described. Clear rectangular shapes repeat the pilasters of the main buildings of the BSTU named after V.G. Shukhov. Symbolic Latin letters “BSTU” (Belgorod State Technological University) have been created as the main art object, performing not only an enclosing function, but also creating additional seating.
Konstanty Gorsky’s Songs on Polish texts: aspects of genre stylistics
Authors: Hanna Marynchak
Published: August 2022

Statement of the problem. K. Gorsky’s creativity has not been studied enough. Relatively recently, articles by R. Aladova (2005), G. Serochinsky (2010), V. Luniakyna (2009), T. Bakhmet (2009) and other authors have been published due to the growing public interest in his creative figure. However, the vocal works by K. Gorsky have not yet been studied in their multi-level connections with national, historical and genre stylistics, as well as the predominant genre of solo singing, on the basis of which the composer formed the intonation specifics of his own chamber vocal style. Therefore, there is a need for further study of the vocal style of K. Gorsky, in particular, the inclusion of his works in a wide repertoire of concert and chamber singing. The purpose of the study is to identify the stylistic features of the key genre of K. Gorsky’s vocal works – the romance, which is most clearly represented in the cycle “12 Romances” based on the texts of the Polish poets – M. Konopnicka, W. Syrokomla, Z. Dembitsky (Dębicki). For the first time, an integrated approach is applied to the songs by K. Gorsky, as to original examples of this genre interpretation in the post-romantic era, with an emphasis on their style features – national and “personal”. The work on the research topic required the use of general scientific and special musicological methods, including historical-genetic, deductive approaches, genre-stylistic and performance analysis. Results and conclusions. The legacy of K. Gorsky (1859–1924), a virtuoso violinist, one of the founders of the musical culture of Kharkiv, includes vocal genres. In the mature period of his activity (1900s), the composer focused specifically on vocal genres, namely romances (he created about 100 pieces), arrangements of Ukrainian folk songs, cantatas on spiritual themes, choral concerts and operas. The main features of his romantic outlook, combined with the Polish musical mentality, are concentrated in “12 Songs” with Polish lyrics. Semantically, K. Gorsky’s romances gravitate toward lyrical contemplation, conveying its various states, from “objective” epics and sound imagery to emotional outbursts, which brings them closer to opera arioso. Within the framework of the cycle, there is an allocation and alternation of songs-romances of four semantic modes: folkpoetic, reflexive-lyrical, graceful-salon, free-declamatory reminiscent of “poetry with music”. Each of these groups is based on certain traditions and requires appropriate means of performance interpretation.

Centroidal Voronoi Tessellation and Model Predictive Control–Based Macro-Micro Trajectory Optimization of Microsatellite Swarm
Authors: Wu Xiwei , Xiao Bing , Wu Cihang , Guo Yiming
Published: August 2022

Probabilistic swarm guidance enables autonomous microsatellites to generate their individual trajectories independently so that the entire swarm converges to the desired distribution shape. However, it is essential to avoid crowding for reducing the possibility of collisions between microsatellites. To determine the collision-free guidance trajectory of each microsatellite from the current position to the target space, a collision avoidance algorithm is necessary. A synthesis method is proposed that generate the collision avoidance trajectories. The idea is that the trajectory planning is divided into macro-planning and micro-planning; macro-planning guides where the microsatellites move step by step from the initial cube to the target cube by probabilistic swarm guidance with Centroidal Voronoi tessellation, while the micro-planning is to generate the optimal path for each step and finally reach the specified position in the target cube by model predictive control. Simulation results are presented for the collision-free guidance trajectory of microsatellites to verify the benefits of this planning scheme.

Published: August 2022

The one-pot combination of biocatalytic and chemocatalytic reactions represents an economically and ecologically attractive concept in the emerging cascade processes for manufacturing. The mutual incompatibility of biocatalysis and chemocatalysis, however, usually causes the deactivation of catalysts, the mismatching of reaction dynamic, and further challenges their integration into concurrent chemo-biocascades. Herein, we have developed a convenient strategy to construct versatile functional metal–organic framework micro-nanoreactors (MOF–MNRs), which can realize not only the encapsulation and protection of biocatalysts but also the controllable transmission of substances and the mutual communication of the incompatible chemo-biosystems. Importantly, the MOFs serving as the shell of MNRs have the capability of enriching the chemocatalysts on the surface and improving the activity of the chemocatalysts to sufficiently match the optimum aqueous reaction system of biocatalysts, which greatly increase the efficiency in the combined concurrent chemo-biocatalysis. Such strategy of constructing MOF–MNRs provides a unique platform for connecting the “two worlds” of chemocatalysis and biocatalysis.

Iontronic sensors represent a novel class of soft electronics which not only replicate the biomimetic structures and perception functions of human skin but also simulate the mechanical sensing mechanism. Relying on the similar mechanism with skin perception, the iontronic sensors can achieve ion migration/redistribution in response to external stimuli, promising iontronic sensing to establish more intelligent sensing interface for human-robotic interaction. Here, a comprehensive review on advanced technologies and diversified applications for the exploitation of iontronic sensors toward ionic skins and artificial intelligence is provided. By virtue of the excellent stretchability, high transparency, ultrahigh sensitivity, and mechanical conformality, numerous attempts have been made to explore various novel ionic materials to fabricate iontronic sensors with skin-like perceptive properties, such as self-healing and multimodal sensing. Moreover, to achieve multifunctional artificial skins and intelligent devices, various mechanisms based on iontronics have been investigated to satisfy multiple functions and human interactive experiences. Benefiting from the unique material property, diverse sensing mechanisms, and elaborate device structure, iontronic sensors have demonstrated a variety of applications toward ionic skins and artificial intelligence.

Human Nutrition and Dietetics: Understanding the Profession and Development Actions in Jordan
Authors: Ahmad Mousa Numan
Published: August 2022

In Jordan, human nutrition and dietetics are among the most developed allied health professions, but documented information regarding its current status is generally not available. The purpose of this article is to clarify the status of this profession in the country and to trace the developmental activities that have taken place over the past five decades. Currently, there have been remarkable transitions in health attributes among Jordanians as related to nutritional status since fifty years ago. This is manifested in rapid dietary, socio-economic, epidemiologic, and demographic shifts. Accelerated changes have occurred in general health and nutritional status trends, including a decline in the incidence of infectious diseases, increased life expectancy, a surge in all levels of education, rise in urbanization, mechanization and market globalization, decreased physical activity, diets have become denser in energy and richer in carbohydrates, fat, and animal foods. Concordant troubling trends have been recorded for rising morbidity and mortality of major nutrition-related chronic disorders, particularly cardiometabolic risks including diabetes, obesity, cardiovascular disease, dyslipidemia, hypertension, as well as cancer. Consistency with this transition, patterns of nutrition and dietetics profession services have increased steadily. There are 10 public and 17 private universities in Jordan. Six public and five private universities offer degrees in human nutrition. One offers a doctoral degree, four offer a master's degree, and all eleven universities offer bachelor's degrees in human nutrition and/or dietetics or both. In line with these changes, the human nutrition and dietetics profession has gained significant official recognition and legal status permitting certification or licensing and consultation and private practice. However, additional legislative and regulatory attributes, internships and in-service training programs, and national diet manuals are required for such progress to continue at a steady pace. Therefore, there is a need for an official body to shape the landscape of the profession of human nutrition and dietetics in accordance with international standards.
Changes in Chemical and Physical Quality Attributes of Olives as Influenced by Chemical Control of the Olive Fruit Fly, Bactrocera oleae (Rossi) (Diptera, Tephritidae) in Jordan

Published: August 2022

The olive fruit fly, Bactrocera oleae (Rossi) (Diptera, Tephritidae) is the most devastating insect pest possessing severe economic threats for the olive growers in Jordan. Therefore, the current study aimed at determining the effect of insecticidal applications against B. oleae on olive quantity, as well as physical (refractive index, fruit weight, diameter and volume, and weight of seed and flesh, as well as oil percentage) and chemical (olive oil acidity and peroxide value parameters). The experiment was conducted using Nabali olive cultivar in Karak District-Jordan in the year 2016. Three insecticides; Karate, Fytoclean, and Dursban used in the spraying operations, and trees were sprayed twice. Insecticidal spraying significantly (P<0.05) reduced olive oil acidity, peroxide value, and refractive index, and increased olive fruit’s weight, diameter and volume, and seed, and flesh weight compared to the untreated trees. In conclusion, the application of insecticides against B. oleae improved the olive quantity and tested quality parameters.

Published: August 2022

The high demand for fish as a protein source in fishmeal with the increasing production pressure on aquaculture has led to the research on the use of insects as an alternative source of protein for fish production. Studies have been reported on nutritional potentials of some insect’s protein on growth indices with little attention on the fish carcass's proximate composition and amino acid analyses; thus, this study was conducted to investigate the carcass proximate and amino acid analyses of hybrid catfish fed supplemented cockroach meal. Four experimental diets were formulated with varying inclusion levels of the insect (Diet A (100% fishmeal), Diet B (100% cockroach meal), Diet C (50% fishmeal and 50% cockroach meal), and Diet D (Commercial diet)).  The hybrid catfish were fed twice daily with formulated/commercial diets for 12 weeks. After, the 12-week periods, pool samples of whole fish, were sacrificed for proximate analyses and amino acid analyses. The test fish carcass revealed the highest moisture content (9.22±0.01%) and crude protein (66.23±0.02%) values in Diet A and B respectively. Similarly, the highest crude fiber, ash, and carbohydrate content of 0.73±0.03%, 13.96±0.10%, and 12.55±0.13% were recorded in fish-fed diet B. The amino acid profiles of fish carcass fed diet B recorded the highest values of lysine, phenylalanine, methionine, proline, arginine, cysteine, alanine, and glutamic acid; glycine, threonine, and serine. Whilst other amino acids monitored in fish fed Diet B were moderate amongst others. The fish fed Diet C, also recorded positive (p<0.05) proximate compositions and amino acid profiles compared to the control carcass. The observed carcass proximate compositions and amino acid profiles in fish-fed Diets B and C may be attributed to the presence of cockroach meal in the diets. Hence, the inclusion of cockroaches in the diets of hybrid catfish could be employed as a potential source of protein for catfish fingerlings as revealed by the hybrid catfish carcass proximate composition and amino acid analyses. this makes a potential source of protein for human consumption

Published: August 2022

The present research empirically determined the factors influencing total factor productivity (TFP) of sugarcane producers in the Kwara State of Nigeria. Data were obtained from using the 2017-2018 sugarcane cropping season field survey through the administration of a structured questionnaire complemented with an interview schedule on 105 sugarcane farmers selected via multi-stage sampling technique. The collected data were analyzed using the conventional TFP index and censored regression model. From the empirical findings, it was observed that inefficiency in the allocation of working capitals, capital consumption, and health-related challenges decreased the TFP of sugarcane farmers in the studied area. However, the study advised the extension agents to educate farmers to be rational in resource allocation in order to optimize their productivity in sugarcane production. In addition, the study advised farmers to adopt health precautious measures in order not to predispose their family members to tropical diseases and should imbibe savings and investment cultures

Published: August 2022

In present work a simple, economic, accurate and precise HPLC method with UV detection was developed for the quantification of zonisamide (ZON) in spiked human plasma using trimethoprim (TRI) as an internal standard. Both ZON and TRI were well separated and resolved from each other on C18 column using mobile phase blend of methanol: acetonitrile: 20 mM phosphate buffer (pH 3.0) in an isocratic mode at flow rate of 1 mL/min with proportion of 25:5:70 %, v/v/v. The detector wavelength was set at 240 nm. Maximum recovery of ZON and TRI from plasma were obtained with dichloromethane (DCM) as extracting solvent. The calibration curve was found to be linear in the range of 3-60 mg/mL with regression coefficient (r2) = 0.997. The LLOQ of the method was 3 mg/mL. Although, with acceptable r2, heteroscedasticity of the calibration data was observed which further was reduced with use of weighted linear regression with weighting factor 1/x. Finally, the method was validated with respect to sensitivity, accuracy, precision, recovery, stability and for carry-over as per US-FDA guidance for Bioanalytical Method Validation, May 2018.

Conducting research in emergency settings is paramount to advance knowledge and experiences on dealing with critically ill patients. However, the involvement of highly vulnerable subjects, who are mostly incapable of consenting to research participation is challenging. This research paper describes the extent of emergency research and its related ethical issues within emergency settings in the Middle East. A literature review covering several databases was conducted. Several studies conducted within the emergency departments in the Middle Eastern region were located. All studies focused on provision of emergency care, while none described aspects of emergency research. Current literature indicates a dearth of research concerning emergency research settings in developing countries mainly in the Middle Eastern region. Up to the authors’ knowledge, this is the first research paper to review the available literature on emergency research in the Middle East. Findings from this review suggests that more efforts focusing on emergency research should be encouraged and stimulated in the region, in order to improve the effectiveness and safety of healthcare provision to critically ill patients within emergency departments. Adding to that, our findings stimulate the needs for regulatory bodies and regulations that help overcome the main ethical issues surrounding the principle of obtaining informed consents in emergency settings.

The major obstacle in controlling malaria is the mosquito’s resistance to insecticides, including pyrethroids. The resistance is mainly due to the over-expression of detoxification enzymes such as cytochromes. Insecticides tolerance can be reduced by inhibitors of P450s involved in insecticide detoxification. Here, to design potential CYP6P3 inhibitors, a homology model of the enzyme was constructed using the crystal structure of retinoic acid-bound cyanobacterial CYP120A1 (PDB ID: 2VE3; Resolution: 2.1 Å). Molecular docking study and computational modeling were employed to determine the inhibitory potentials of some phytoligands isolated from Ficus sycomorus against Anopheles coluzzii modeled P450 isoforms, CYP6P3, implicated in resistance. Potential ligand optimization (LE) properties were analyzed using standard mathematical models. Compounds 5, 8,and 9 bound to the Heme iron of CYP6P3 within 3.14, 2.47 and 2.59 Å, respectively. Their respective binding energies were estimated to be -8.93, -10.44, and -12.56 Kcal/mol. To examine the stability of their binding mode, the resulting docking complexes of these compounds with CYP6P3 were subjected to 50 ns MD simulation. The compounds remained bound to the enzyme and Fe (Heme):O (Ligand) distance appeared to be maintained over time. The coordination of a strong ligand to the heme iron shifts the iron from the high- to the stable low-spin form and prevented oxygen from binding to the heme thereby inhibiting the catalytic activity. The LE index showed the high potential of these compounds (5 and 8) to provide a core fragment for optimization into potent P450 inhibitors.
