Effect of Lipid Peroxidation on Dental Healthcare Workers

Aim and Objective: The relevance of the study was explained by the fact that free radicals, known to be a product of lipid peroxidation, damage the integrity of cell membranes and corresponding intracellular structures, disrupting their functioning. The purpose of this cross-sectional study was to investigate the effect of free-radical lipid peroxidation in the blood on the body of dentists without diseases of the bronchi and lungs. Materials and Methods: The chemiluminescent properties of the blood hemolysate of 65 dentists were measured. Blood was collected in a test tube with an anticoagulant, and the plasma was aspirated with a Pasteur pipette. The hemolysate was aspirated two times. Distilled water was added to the sediment of erythrocytes, the mixture was shaken, and centrifuged. Statistical processing of morphometric indicators was carried out using the software package “Statistica 6.0. ”Results: The direct dependence of the spontaneous chemiluminescence (SCL) growth parameters in the blood hemolysate of dentists on their length of service was determined. Conclusion: The conclusions indicate a direct correlation between the growth parameters of the SCL index in the blood hemolysate of dentists and their length of service. The applied value of this study lies in the possibility of practical application of the results obtained to qualitatively investigate the effect of lipid peroxidation processes on the body of dentists.
Comparative Analysis of Two Pear Pests, Cacopsylla jukyungi and Cacopsylla burckhardti (Hemiptera: Psyllidae), Based on Complete Mitochondrial Genomes and Comparison to Confamilial Species

Mitochondrial genome sequences have been used in diverse fields of biology. In this study, we sequenced the complete mitochondrial genomes (mitogenome) of two pear pests: Cacopsylla jukyungi, the most damaging insect pest to commercial pears in South Korea, and Cacopsylla burckhardti (Hemiptera: Psyllidae). The two mitogenomes were compared to confamilial species to accumulate genetic information and understand evolutionary characteristics of the family Psyllidae. The 15,438 bp-and 14,799 bp-long complete mitogenomes of C. jukyungi and C. burckhardti, respectively, had many features typical of insect mitogenomes; however, at 1283 bp, the C. jukyungi mitogenome had an unusually long A+T-rich region, which was composed of two identical 540-bp repeat sequences. Among the intergenic spacer regions, the one located at the ND1 and trnS2 junction was relatively well conserved in length (mostly within 23–36 bp). This region had a high sequence identity in all Psyllidae, possessing a 5-bp consensus sequence (CGGTA), which is speculated to have a functional role. Though the A+T-rich region in available Psyllidae mitogenomes varied substantially in length (662–1430 bp) and sequence divergence, all species had a conserved sequence stretch at the 3′-end of srRNA, which is also speculated to have a functional role. Genetic divergence among genes indicated the lowest variability in srRNA, lrRNA, and COI, whereas ATP8 and ND6 showed the highest variability at both family and genus (Cacopsylla) levels. Our data provide evidence that the family Psyllidae, including current C. jukyungi and C. burckhardti, have evolutionary unique features that were previously undetected, along with the unique A+T-rich region structure in C. jukyungi.
The incidence and morphology of the Gantzer’s muscle in a Kenyan population

Gantzer’s muscle is an accessory head of the flexor pollicis longus (FPL). Its incidence, attachments as well as relations to nervous structures have been shown to exhibit population variations, which have important clinical bearings. Data from our setting however remains partly elucidated. To study the muscle, the skin of the anterior forearm and fascia were removed to expose the flexor compartment of the forearm. The flexor muscles were also identified and reflected. The Ganzter’s muscle was identified as that muscle belly originating from the flexor digitorum superficialis, the radius, the medial humeral epicondyle or the ulna coronoid process and inserted on the flexor pollicis longus or the flexor digitorum superficialis muscle. Its prevalence, laterality, origin, insertion, shape and relation to the anterior interosseous nerve were determined. The data obtained was entered into SPSS and percentages calculated for the different variables. The muscle was found in 19/43 (44%) cadavers on the right and on 20/43 (46%) on the left. In 5 out the 43 cadavers (11%), the muscle was present bilaterally while in the rest, it existed solely as either on the right orleft (predominantly on the left, 46%). The Gantzer’s muscle was also noted to predominantly originate from the Flexor Digitorum Superficialis muscle (72% on the left, 76% on the right) and insert on the Flexor pollicis longus (100%). As regards its shape, it was predominantly triangular, on both right side (65%) as well as the left side (54%). In majority of the cases, the muscle also lay posterior to the anterior interosseous structures (100% on the left and 89% on the right). In conclusion, the Gantzer’s muscle is relatively common in our population, exhibits marked population variations and as such should be taken into account especially during surgical approach to the anterior elbow to avoid its inadvertent injury.
Cloud-based accounting information systems usage and its impact on Jordanian SMEs’ performance: the post-COVID-19 perspective

Purpose The purpose of this study is to examine the factors influencing the usage of cloud-based accounting information systems (AIS) in the crisis era (i.e. the COVID-19 pandemic) by expanding the unified theory of acceptance and use of technology (UTAUT) with new related critical factors. Design/methodology/approach A quantitative research approach based on a cross-sectional online questionnaire was used for collecting empirical data from 438 potential and current users of cloud-based AIS. Structural equation modeling based on analysis of a moment structures 25.0 was applied in the data analysis. Findings The outcome of the structural path revealed that performance expectancy, social motivation, COVID-19 risk (COV-19 PR) and trust (TR) were significantly influencing users’ behavioral intention (BI) toward using cloud-based AIS and explained 71% of its variance. While, contrary to what is expected, the impact of effort expectancy and perceived security risk (SEC) on BI was insignificant. In addition, BI was revealed to influence the actual usage behaviors and explained 74% of its variance. The outcome factors: communication quality (CQ) and decision quality (DQ) were significantly influenced by the usage of cloud-based AIS. Practical implications The current research would be valuable for small- and medium-sized enterprises officials and policymakers to illustrate the relatively low rates of cloud-based AIS and formulate strategies to boost the acceptance and use of cloud-based AIS by Jordanian users, where cloud-based services are still deemed as an innovation. Originality/value To the best of the authors’ knowledge, the current study is the first academic paper that extends the UTAUT by integrating additional factors: TR, SEC and COV-19 PR. In addition to two outcome variables: CQ and DQ, to study the cloud-based AIS in the Jordanian setting beyond the COVID-19 pandemic. The current research contributes to the academic knowledge on information technology information system adoption by considering cloud accounting acceptance and use and integration into the work practices of users through the BIs and actual use of cloud-based AIS in Jordan.
Exponential Stability of Fractional-Order Impulsive Control Systems With Applications in Synchronization

This paper investigates exponential stability of fractional-order impulsive control systems (FICSs) and exponential synchronization of fractional-order Cohen–Grossberg neural networks (FCGNNs). First, under the framework of the generalized Caputo fractional-order derivative, some new results for fractional-order calculus are established by mainly using L’Hospital’s rule and Laplace transform. Besides, FICSs are translated into impulsive differential equations with fractional-order via utilizing the definition of Dirac function, which reveals that the effect of impulsive control on fractional systems is dependent of the order of the addressed systems. Furthermore, exponential stability of FICSs is proposed and some novel criteria are obtained by applying average impulsive interval and the method of induction. As an application of the stability for FICSs, exponential synchronization of FCGNNs is considered and several synchronization conditions are established under impulsive control. Finally, several numerical examples are provided to illustrate the effectiveness of the derived results.
Current Advances in Lung Ultrasound in COVID-19 Critically Ill Patients: A Narrative Review

Lung ultrasound (LUS) has a relatively recent democratization due to the better availability and training of physicians, especially in intensive care units. LUS is a relatively cheap and easy-to-learn and -use bedside technique that evaluates pulmonary morphology when using simple algorithms. During the global COVID-19 pandemic, LUS was found to be an accurate tool to quickly diagnose, triage and monitor patients with COVID-19 pneumonia. This paper aims to provide a comprehensive review of LUS use during the COVID-19 pandemic. The first section of our work defines the technique, the practical approach and the semeiotic signs of LUS examination. The second section exposed the COVID-19 pattern in LUS examination and the difference between the differential diagnosis patterns and the well-correlation found with computer tomography scan findings. In the third section, we described the utility of LUS in the management of COVID-19 patients, allowing an early diagnosis and triage in the emergency department, as the monitoring of pneumonia course (pneumonia progression, alveolar recruitment, mechanical ventilation weaning) and detection of secondary complications (pneumothorax, superinfection). Moreover, we describe the usefulness of LUS as a marker of the prognosis of COVID-19 pneumonia in the fourth section. Finally, the 5th part is focused on describing the interest of the LUS, as a non-ionized technique, in the management of pregnant COVID-19 women.
Comparative Observational Assessment of Cyclists’ Interactions on Urban Streets with On-Street and Sidewalk Bike Lanes

The competition for urban space and the debate about where people can and should ride their bicycles began not long after this new form of mobility was introduced to the public. For two centuries, we have debated and eventually investigated whether bike lanes belong on the sidewalk or if they should be on the street alongside the vehicular roadway. Existing research has provided evidence of preferences for bike lane alignment based on perceived safety or comfort as well as objective measures of comparative safety based on available crash and hospital data. Much of the existing research has been driven by deductive assumptions or is limited by the lack of data describing near-miss events and the subtle everyday interactions cyclists experience when using different types of cycle facilities. To help us understand better what role everyday interactions play in the relative functionality of sidewalk and on-street bike lanes, an observational study was conducted using a new qualitative–quantitative grounded theory-driven method for identifying and interpreting the outcome of cyclists’ interactions. Using data gathered from 2,583 interactions observed at four case study street segments in Munich, Germany, four outcomes were identified: no reaction; adjusting or yielding; lane exiting; or multiple reactions. Based on inferential analyses of these outcomes, this paper presents an assessment of the safety, directness, and access afforded or hindered by the spatial conditions of observed interactions. The results of this assessment revealed a trade-off between frequent, but minor interactions in sidewalk bike lanes and infrequent, but less safe interactions in on-street bike lanes.
Green economy and sustainable development concepts, principles and requirements for transformation in Iraq

After 2003, Iraq sought to participate in global initiatives that would preserve the climate, and among these initiatives is the new global green initiative, which was launched during the 2008 global financial crisis, which focused on creating a special investment climate in developing countries to transition to a green economy and sustainable development. The volume of donations from donor countries was 3 trillion dollars, and developing countries contributed 15% of this amount. The aim of the research is to know the ways and directions that Iraq has moved to convert to a green economy, and what are the problems it faces and what are the means of financing that would be A positive reason for the transition towards a green and sustainable economy, and the results of this research showed that Iraq has endeavored with great efforts through initiatives that will enable it to transition to a green economy, the most important of which was the green belt strategy that was launched in 2011. The results also showed that Iraq is full of potentials Huge material and human resources are the primary resource for the transition to a sustainable green economy, and the research recommended a number of recommendations that would form a new core and Complementary to what has been raised in other studies, which is increasing pressure on neighboring countries to increase water quotas, which enables Iraq to take advantage of that water in increasing green spaces, as well as raising the performance of local administrations in the governorates in order to adopt green and sustainable awareness within cities, addressing the problem of waste and work to recycle and manufacture it again, and to exploit biological waste and use it as organic fertilizer for farmers.
In Vitro Activity of Cefepime-Enmetazobactam against Gram-Negative Isolates Collected from U.S. and European Hospitals during 2014–2015

Enmetazobactam, formerly AAI101, is a novel penicillanic acid sulfone extended-spectrum β-lactamase (ESBL) inhibitor. The combination of enmetazobactam with cefepime has entered clinical trials to assess safety and efficacy in patients with complicated urinary tract infections. ABSTRACT Enmetazobactam, formerly AAI101, is a novel penicillanic acid sulfone extended-spectrum β-lactamase (ESBL) inhibitor. The combination of enmetazobactam with cefepime has entered clinical trials to assess safety and efficacy in patients with complicated urinary tract infections. Here, the in vitro activity of cefepime-enmetazobactam was determined for 1,993 clinical isolates of Enterobacteriaceae and Pseudomonas aeruginosa collected in the United States and Europe during 2014 and 2015. Enmetazobactam at a fixed concentration of 8 μg/ml lowered the cefepime MIC90 from 16 to 0.12 μg/ml for Escherichia coli, from >64 to 0.5 μg/ml for Klebsiella pneumoniae, from 16 to 1 μg/ml for Enterobacter cloacae, and from 0.5 to 0.25 μg/ml for Enterobacter aerogenes. Enmetazobactam did not enhance the potency of cefepime against P. aeruginosa. Applying the Clinical and Laboratory Standards Institute susceptible-dose-dependent (SDD) breakpoint of 8 μg/ml to cefepime-enmetazobactam for comparative purposes resulted in cumulative inhibitions of 99.9% for E. coli, 96.4% for K. pneumoniae, 97.0% for E. cloacae, 100% for E. aerogenes, 98.1% for all Enterobacteriaceae assessed, and 82.8% for P. aeruginosa. Comparator susceptibilities for all Enterobacteriaceae were 99.7% for ceftazidime-avibactam, 96.2% for meropenem, 90.7% for ceftolozane-tazobactam, 87% for cefepime (SDD breakpoint), 85.7% for piperacillin-tazobactam, and 81.2% for ceftazidime. For the subset of ESBL-producing K. pneumoniae isolates, the addition of 8 μg/ml enmetazobactam to cefepime lowered the MIC90 from >64 to 1 μg/ml, whereas the shift for 8 μg/ml tazobactam was from >64 to 8 μg/ml. Cefepime-enmetazobactam may represent a novel carbapenem-sparing option for empirical treatment of serious Gram-negative infections in settings where ESBL-producing Enterobacteriaceae are expected.
Shear behavior of reinforced concrete beams incorporating waste glass powder as partial replacement of cement

Abstract This work aimed to investigate experimentally the effect of incorporating waste glass powder on the shear behaviour of reinforced concrete beams under bending load in terms of load- vertical displacement relation, load-strain relation, cracks pattern/propagation, load –cracks relation, and mode of failure. The replaced cement partially with waste glass powder achieves two main goals; the first is an economic benefit represented by reducing the cost of supplementary materials and the second one is an environmental benefit represented by solving some of the solid waste problems that waste causes and saving energy. The experimental program consists of testing nine simply supported beams of 150 × 150 × 900 mm designed to fail in shear. Three parameters have been studied; glass powder content (0, 10, and 15% as partial replacement of cement), steel reinforcement ratio equal to 0.02267 (2Φ16mm), and 0.013785 (2Φ12mm), and spacing between stirrups (65 and 170 mm). The test results showed that using glass powder improved the strength capacity of the beam and that can be seen through the increase in ultimate load for beams incorporating glass powder compared to the control beam. Recorded load at failure increased by 39% and 23% for 10% and 15% replacement compared with the control beam. For the same waste glass powder content, an increase in the amount of longitudinal steel reinforcement from 2Φ12 mm to 2Φ16 mm led to an increase in ultimate load but decreases in the corresponding vertical displacement, which refers to more brittle behaviour. In addition, reducing the spacing among the stirrups from 170 mm to 65 mm led to a decrease in ultimate load and increasing in the corresponding vertical displacement. The incorporation of waste glass powder made the behaviour of beams more brittle i.e. for the same load the vertical displacement for beams incorporating waste glass powder (especially for 15%) is lower than for reference beams without waste glass powder, which is not desired. To take advantage of the property of waste glass powder by improving the ultimate strength of the beam, which appeared by increasing the maximum load at failure compared to the reference beam and at the same time preventing the property of brittle failure caused by the addition of this material, it is suggested to use waste glass powder with fibers.
Effect of Different Irrigation Regimes on the Early Development of Pot-Grown Black Locust Saplings

Black locust currently is considered to be the most important tree species of short-rotation forests in Hungary with the purpose of either woody biomass or industrial wood. Despite the general supposition on the drought tolerance of the species, water availability seems to be a more limiting factor to exploit the growing potential of highly productive new varieties than nutrient amendments. Preliminary measurements of the current study were made on the connection between the depth of the water-retaining soil layer and the growth of saplings on black locust plantations. A significant negative correlation was found between the depth of the water-retaining layer, the stem diameter and the height of the saplings. To investigate the phenomenon, a model experiment was launched with loamy sand soil in the pots. During six weeks, pots were watered every morning up to the weight referring to the 30, 40, 60 and 80% of field capacity (FC). Our results showed that 30% FC was only sufficient for the survival of the saplings, growth was only noticeable at plants with 40% FC or more. During the first 4 weeks, differences in growth and cumulative evapotranspiration between the 60% and 80% FC treatment were not considerable. However, in the last two weeks, saplings with the highest FC produced substantially higher biomass, resulting in a one-third higher final weight than those of FC 60%. Even with the limited soil capacity of the pots, water use of these saplings of 1 m height and 1 cm stem diameter exceeded 1.5 L per day. Our results confirmed that black locust is a water-intensive species with a high water use potential, which emphasizes the importance of irrigation on nurseries and the first years of plantations.
Individual variation in children's early production of negation

The ability to express negation is an important part of early language. Despite the fact that negation is a complex and abstract concept, “No” is one of the first words that children produce. Past analyses have found that children’s early negations tend to express concepts like refusal (negations expressing that a child does not want to do something) rather than denial (negations expressing that something is false). Does this mean that young children are incapable of expressing denial? In Study 1, we examine children’s spontaneous production of negation and find that some children produce denial negation earlier and more frequently than past literature suggests. In Study 2, we examine one possible explanation for individual variation in children’s negation production: differences in the joint activities that they engage in with their caregivers. A comparison of two children suggests that reading may be associated with the production of denial negation. We discuss our data in light of previous findings, and suggest that certain communicative contexts are more likely to elicit different types of negation.
Assessing the Emergence of Resistance in vitro and Invivo: Linezolid Combined with Fosfomycin Against Fosfomycin-Sensitive and Resistant Enterococcus

Purpose We aimed to evaluate the synergistic effect of linezolid and fosfomycin on fosfomycin-sensitive and -resistant Enterococcus clinical isolates in vitro and in vivo and whether the emergence of fosfomycin resistance in Enterococcus is associated with changes in strain virulence, from the perspective of fitness cost. Methods The synergistic effect of linezolid and fosfomycin was studied via in vitro checkerboard and static time-kill assays, as well as based on the in vivo survival rate and hemolymph load of a Galleria mellonella infection model. Fosfomycin resistance was induced via a stepwise increase in concentration. Changes in the virulence of the strains after drug resistance were investigated using the G. mellonella infection model and reverse transcription quantitative polymerase chain reaction (RT-qPCR). In vitro and in vivo growth curves and competitive experiments were used to study the fitness cost of the strain. Finally, a static time-kill assay was performed to explore the effect of the combined medication. Results In vitro and in vivo data showed that linezolid combined with fosfomycin had a good synergistic effect on Enterococcus treatment. The G. mellonella infection model and RT-qPCR data showed that the virulence of the resistant strains was weakened to varying degrees. A survival curve and competition experimental data showed that this was related to the fitness cost of strains while acquiring resistance and negatively impacted linezolid treatment; however, the combination still showed a good synergistic effect in drug-resistant strains. Conclusion Linezolid combined with fosfomycin had a synergistic effect on both fosfomycin-sensitive and -resistant Enterococcus strains. Strains incur fitness costs as they develop drug resistance, which leads to a decrease in virulence. There is an interaction between fitness cost, virulence, and drug resistance, which indirectly affects drug treatment.
