Authors:   Assistant Of The Department Of Anatomy, Clinical Anatomy, Samarkand State Medical Institute, Samarkand, Uzbekistan, Mustafoev Zafarjon M.
Published: January 2022

We studied macro and microscopic changes in kidney tissue against the background of polypharmacy when modeling renal pathology. It has been shown that the simultaneous use of more than 5 drugs has a nephrotoxic effect on the proximal renal tubules. On macroscopic examination, the kidneys were bean-shaped, the capsule was smooth; with the help of a magnifying glass, it was smooth, shiny, without visible differences. Microscopically, in the kidney tissue in the study group, some structural differences were revealed, the nature and severity of which depended on the type of active drug. In the glomerular apparatus of the kidneys of rats, focal infiltration of mesangial cells was noted. Moreover, in the direct tubules of the kidney apparatus, remarkable changes were not revealed. Thus, it was concluded that tubular damage leads to impaired tubular reabsorption, proteinuria, the morphological criteria of steatosis, and dysproteinosis of varying degrees.

A Study of the Republic of China as a ‘Political and Territorial Entity’ in the System of International Relations
Authors: Bratuta Yevhen , Bratuta Oleksii
Published: January 2022

The article offers an insight into the circumstances of the emergence, particular features, and prospects of the existence of the Republic of China as an unrecognized state. Specifically, the authors clarify the content of the notion ‘unrecognised state’, which is to be interpreted as a type of a temporary political and territorial entity in the form of a state that does not possess formal characteristics of a member of the world community. The article also identifies the phenomenon ‘Republic of China’ through the specific singular notion ‘unrecognised state’ and outlines a conceptual framework, which allows concluding that there is only one realistic scenario of the country’s future existence, namely uniting with the People’s Republic of China into a single state within one country through political and legal unification.
According to the authors, the Republic of China currently finds itself at the democratic phase of its development in the form of an unrecognised state. Together with leading countries, it is deeply integrated into the world system, being not only a component of the globalised world but also one of the factors contributing to the spread of globalization processes into the mega level of social existence. Drawing upon the research on the problems in the emergence and functioning of new political and territorial entities in the form of unrecognised states conducted by Ukrainian and foreign scholars, it can be argued that the notion ‘unrecognised state’ is yet to be finally defined. Therefore, correct identification of new political and territorial entities is impossible. The authors propose, at the level of political leadership, devising and approving a foreign policy strategy of launching and building relations between Ukraine and the Republic of China in the economic and humanitarian fields, using the international experience of establishing economic and cultural offices in partner states.
Keywords: system of international relations, political and territorial entity, state, unrecognized state, the Republic of China.
Volodymyr Zelenskyy’s Diplomacy in Resolving the Russian Ukrainian Conflict in Donbas
Authors: Perepelytsia Hryhorii
Published: January 2022

The author of the article examines the phenomenon of the Russian-Ukrainian conflict in Donbas, the main trends in its development and resolution, the strategies of the parties in this process as well as miscalculations and achievements of Volodymyr Zelenskyy’s diplomacy in gaining peace in Donbas and ending the war with Russia.
The author underscores that the Russian-Ukrainian war in Donbas is not only the most acute all-Ukrainian problem but also a sore international issue, which calls into question the existence and survival of the Ukrainian state, the future of European security and the current world order. Seven years into the war, which is officially referred to as the ‘Russian-Ukrainian conflict’, no answer has been found on how to end it. The issues of ending the war against Russia, reimbursing the losses caused by it, establishing peace in Donbas, and returning the occupied territories of Ukraine are the most significant in the foreign policy of President of Ukraine V. Zelenskyy. Yet, the diplomatic strategy he chose has not so far provided the definitive answer to this question, whose solution is expected by Ukrainian citizens both in the liberated and Russian-occupied territories of Donbas. The international community, including its security organisations, does not have a clear and unambiguous answer to this question as well.
This article is a certain attempt to analyse the efforts of V. Zelenskyy’s diplomacy to resolve this security problem over the last two years of his presidency. According to the author, the search for alternative ways to achieve peace has not brought the desired results this year. Therefore, Ukraine has only one choice – to recognise the Russian-Ukrainian war as a reality and to be ready for Russia’s large-scale military aggression at any moment.
Keywords: Russian-Ukrainian conflict, diplomacy, Normandy format, Minsk process, ‘Yermak plan’, election, strategies of the parties, war, peace, ‘Steinmeier formula’.

Authors: Savrasovs Mihails , Yatskiv (Jackiva) Irina , Tolujevs Jurijs , Jackson Ilya
Published: January 2022

This research considers the aspects of decision-making according to the airport activities. The decision about airport planning and management should be comprehensive and operative and of course, the assessment of alternative decisions is necessary. The purpose of this research is to highlight the role of simulation modelling at the stage of airport development. The authors present the methodology of a model-driven decision-making approach and then describe 2 cases of using simulation for Riga International Airport (RIX) development. The 1st case study is used for analysis possibility of the development of the airport’s surrounding territory. The planned massive development of RIX and the surrounding area requires detailed analysis for increasing its positive impact on regional and national business economics, social aspects, business and the environment. The 2nd case supports decision-making for the needs of the terminal reconstruction, presents a helpful tool for visualization of the tendencies in the future, and allows the analysis of the different infrastructure layouts. Both cases give the possibility to predict the situation and evaluate the service provided for passengers (travellers) of the airport. Simulation modelling allows to study complex system – airport and evaluate direct and indirect impacts of planned reconstruction.
X-Ray Imaging Observations of the High-mass γ-Ray Binary HESS J0632+057

Published: January 2022

The Chandra X-Ray Observatory (CXO) imaged the high-mass γ-ray binary HESS J0632+057 with the Advanced CCD Imaging Spectrometer (ACIS). We analyzed the CXO data together with 967 ks of archival Swift-XRT observations. On arcsecond scales we find a hint of asymmetric extended emission. On arcminute scales, a region of extended emission (“the blob”), located

east of the binary, is seen in both the CXO-ACIS and the Swift-XRT images. The blob does not have a counterpart in the radio, near-IR, IR, or optical images. The ACIS spectrum of the blob fits either an absorbed power-law model with Γ ≃ 2.6, or a thermal plasma model with kT ≃ 3 keV. Since the blob’s N
H is significantly higher than that of the binary we conclude that the blob and binary are not directly related. The somewhat larger, very deep XRT image suggests that the binary may be located within a shell (or cavity). The four ACIS spectra taken within the ∼20 day interval near the light-curve minimum suggest that N
H varies on timescales of days, possibly due to the inhomogeneous circumbinary environment. The XRT spectra extracted from wider orbital phase intervals support significant changes in N
H near the light-curve maximum/minimum, which may be responsible for the substantial systematic residuals seen near 1 keV, and provide tentative evidence for an Fe line at 6.4 keV. We find no significant periodic signal in the ACIS data up to 0.156 Hz.

Understanding how material accretes onto the rotationally supported disk from the surrounding envelope of gas and dust in the youngest protostellar systems is important for describing how disks are formed. Magnetohydrodynamic simulations of magnetized, turbulent disk formation usually show spiral-like streams of material (accretion flows) connecting the envelope to the disk. However, accretion flows in these early stages of protostellar formation still remain poorly characterized, due to their low intensity, and possibly some extended structures are disregarded as being part of the outflow cavity. We use ALMA archival data of a young Class 0 protostar, Lupus 3-MMS, to uncover four extended accretion flow–like structures in C18O that follow the edges of the outflows. We make various types of position–velocity cuts to compare with the outflows and find the extended structures are not consistent with the outflow emission, but rather more consistent with a simple infall model. We then use a dendrogram algorithm to isolate five substructures in position–position–velocity space. Four out of the five substructures fit well (>95%) with our simple infall model, with specific angular momenta between 2.7–6.9 × 10−4 km s−1 pc and mass-infall rates of 0.5–1.1 × 10−6

Energy Levels of Singly Ionized and Neutral Hafnium
Authors: Lawler J. E. , Schmidt J. R. , Den Hartog E. A.
Published: January 2022

Improved energy levels for singly ionized and neutral hafnium of both even and odd parity are determined from Fourier transform spectrometer data using a least-squares optimization procedure. Data from interferometric spectrometers provide much tighter control of systematic uncertainties of line position measurements than can be achieved using dispersive spectrometers. The strong optical and near-UV lines connecting these levels are most likely to be used in the determination of isotopic abundance patterns. Comparisons of new results to published ones strongly suggest that our energy levels have systematic uncertainties in the mK (1 mK = 0.001 cm−1) range or smaller, and that widely used tables of energy levels for ionized Hf have systematic errors of approximately 70 mK.

Studying materials released from Jupiter-family comets (JFCs)—as seen in their inner comae, the envelope of gas and dust that forms as the comet approaches the Sun—improves the understanding of their origin and evolutionary history. As part of a coordinated, multiwavelength observing campaign, we observed comet 45P/Honda–Mrkos–Pajdušáková during its close approach to Earth in 2017 February. Narrowband observations were taken using the Bok 90″ telescope at Kitt Peak National Observatory on February 16 and 17 UT, revealing gas and dust structures. We observed different jet directions for different volatile species, implying source region heterogeneity, consistent with other ground-based and in situ observations of other comet nuclei. A repeating feature visible in CN and C2 images on February 16 was also observed on February 17 with an interval of 7.6 ± 0.1 hr, consistent with the rotation period of the comet derived from Arecibo Observatory radar observations. The repeating feature’s projected gas velocity away from the nucleus is 0.8 km s−1, with an outflow velocity of 0.5 km s−1. A bright compact spot adjacent to the nucleus provides a lower limit of the amount of material released in one cycle of ∼9.2 kg, depending on composition—a quantity small enough to be produced by repeated exposure of nucleus ices to sunlight. This repeating CN jet, forming within 400 km of the nucleus, may be typical of inner-coma behavior in JFCs; however, similar features could be obscured by other processes and daughter product species when viewed from distances further than the scale length of CN molecules.

Premières « impressions » : publier Molière dans l’Angleterre du premier XVIII e siècle
Authors: Jones Suzanne
Published: January 2022

Après l’interrègne anglais et la réouverture des théâtres en 1660 on assista à un afflux de traductions de Molière. Alors que les traducteurs initiaux adoptaient une approche cibliste, le premier xviii e  siècle fut marqué par une double stratégie : créer des adaptations pour la scène et surtout promouvoir l’œuvre moliéresque sous forme imprimée. Cet article a pour but d’explorer la création de l’image de Molière outre-Manche en s’appuyant sur les paratextes, les médias naissants, et les gravures.
Le « bel esprit » en terre inconnue. Les Précieuses ridicules et leurs premières traductions allemandes (1670-1752)
Authors: Wagniart Anne
Published: January 2022

En Allemagne, Molière fut joué et traduit de son vivant. Le prestige du « comédien du roi de France » y était inégalé jusqu’à la deuxième moitié du xviii e  siècle. Cet article retrace trois paliers de la première réception allemande du modèle moliéresque de la haute comédie « sociétale », à l’exemple des Précieuses ridicules , en étudiant leurs traductions et adaptations de 1670, du tournant du siècle et de 1752, dans le contexte du décalage civilisationnel et culturel alors existant entre les deux pays. La réception allemande de la pièce progresse de l’incompréhension à l’assimilation puis à l’émancipation du modèle civilisationnel français évoqué.
Molière en Espagne au XVIII e siècle : présences, traductions, adaptations

Le poids de la tradition dramatique espagnole du xvii e  siècle imposait aux pièces traduites des structures de genre et des mécanismes d’expression qui rendaient difficile une traduction « fidèle » de la comédie classique française. Dans ce contexte, on peut constater que le théâtre de Molière a connu dans l’Espagne du xviii e  siècle des vicissitudes liées aux conditions de composition et de représentation théâtrales, notamment des transformations en saynètes, comportant des changements des structures et des réductions des contenus.

Published: January 2022

In this paper, we consider $ S $-chains of extremal self-dual and self-orthogonal codes and their applications in the construction of quantum codes. Then, by virtue of covering radius, we determine necessary conditions for linear codes to have subcodes with large dual distances and design a new $ S $-chain search method. As computational results, 18 $ S $-chains with large distances are obtained, and many good quantum codes can be derived from those $ S $-chains by Steane construction, some of which improve the previous results.

Authors: Alqhtani Manal ,   Department of Mathematics, College of Sciences and Arts, Najran University, Najran, Saudi Arabia, Saad Khaled M.
Published: January 2022

The main object of this paper is to investigate the spectral collocation method for three new models of space fractional Fisher equations based on the exponential decay kernel, for which properties of Chebyshev polynomials are utilized to reduce these models to a set of differential equations. We then numerically solve these differential equations using finite differences, with the resulting algebraic equations solved using Newton 's method. The accuracy of the numerical solution is verified by computing the residual error function. Additionally, the numerical results are compared with other results obtained using the power law kernel and the Mittag-Leffler kernel. The advantage of the present work stems from the use of spectral methods, which have high accuracy and exponential convergence for problems with smooth solutions. The numerical solutions based on Chebyshev polynomials are in remarkably good agreement with numerical solutions obtained using the power law and the Mittag-Leffler kernels. Mathematica was used to obtain the numerical solutions.
Hybrid Approach Using Deep Autoencoder and Machine Learning Techniques for Cyber-Attack Detection
Authors: Kumar Vikash , Sinha Ditipriya
Published: January 2022

The feature reduction from the vast amount of data collected from the Internet is challenging and labor-intensive. Data imbalance is another problem in decision-making analysis that leads to a biased model favoring classes with larger samples. This paper proposes a hybrid model using autoencoder and machine learning models. It deals with feature reduction and handles imbalance attack classes using SMOTE method to balance the dataset, and then AE is trained. The bottleneck code of AE is stacked with different classifiers on datasets such as NSL-KDD, UNSW-NB15 and BoT-IoT to evaluate the proposed method. The performance of the proposed approach shows improvement over attack detection without AE. The most noticeable change occurred for SVM on the NSL-KDD dataset that shows doubled improvement of accuracy. In the case of UNSW-NB15, the results vary and see an improvement for the LR model. The BoT-IoT dataset sees the lowest performance variation, i.e., 0%-6%.
Neuro-Immune Model Based on Bio-Inspired Methods for Medical Diagnosis
Authors: Djahafi Fatiha , Gafour Abdelkader
Published: January 2022

In this article, a hybrid bio-inspired algorithm called neuro-immune is proposed based on Multi-Layer Perceptron Neural Network (MLPNN) and the Clonal Selection Classification (CSC) principle of the Artificial Immune System (AIS) for the classifying and diagnosing of medical disease. The proposed approach consists in the first phase to code the weights and biases of MLPNN concatenation vector of the input samples into an antigen vector and to decompose it into new weights to generate population memory cells which will be applied by the processes of the CSC algorithm clone and mutate in the second phase, to optimize the accuracy class of data and updating the MLPNN weights to minimize the mean squared error. Experimental results show that the proposed hybrid neuro-immune model allows obtaining a high diagnosis performance on a set of medical data problems from the UCI repository with an improved classification accuracy compared to existing works in the literature.

Published: January 2022

Society witnesses that technology, especially information technology, plays a more and more important role in business and other areas. Not surprisingly, the new 2020 business accreditation standards by the Association to Advance Collegiate Schools of Business International (AACSB) have added technological competency and agility to reflect this trend. While most students know that information technology is important, teaching information technology in a business course of a business program has always been a challenge. Due to the AACSB requirement, technological competency may become one of the learning goals of business programs, and how to assess it becomes a new task to most business programs. This paper presents a new approach to teaching information technology courses and an innovative technological competency assessment instrument and effectiveness at an AACSB accredited school of business.

Authors: Idrees Amira M. , Khedr Ayman E.
Published: January 2022

One main potential objective for financial corporations is to retain long-term customers. Configuring customer knowledge is no doubt mandatory to lower the risk level. Loans and credit cards granting are two services that are offered by the banking corporations which can be categorized as high-risk services. Therefore, it is highly recommended for the corporations to have intelligent support for providing an accurate granting decision which naturally leads to minimizing the associated risk. In this research, a decision support model is proposed for loans granting. The proposed model applies a set of data mining techniques in a collaborative environment that aims at applying different techniques with considering their results according to the technique’s evaluation weight. The proposed model results present the recommendation for each customer’s loan granting a request to be either accepted or rejected. The proposed approach has been applied the on a loan granting dataset and the evaluation results revealed its superiority by 92% success in reaching high accurate decisions.

An Adaptive Fuzzy-Based Two-Layered HRRN CPU Scheduler
Authors: Raheja Supriya
Published: January 2022

Fuzzy Based CPU scheduler becomes an emerging component of an operating system. It can handle the imprecise nature of parameters used in scheduler. This paper introduces an adaptive fuzzy based Highest Response Ratio Next CPU scheduler which is an extension of conventional CPU scheduler. Proposed scheduler works in 2 layers. At the first layer, a Fuzzy Inference System is defined which handles the uncertainties of parameters and at the second layer, an adaptive scheduling algorithm is used to schedule each task. Proposed scheduler intelligently generates the response ratio for each ready to run task which makes the system adaptive at run time. The work is compared with the conventional highest response ratio next scheduling and the existing fuzzy highest ratio next scheduling algorithms. Results validate the better performance of proposed scheduler. The proposed scheduler also provides comparable results with respect to shortest job first scheduling and shortest remaining task first scheduling algorithms.
AHP and SMART Criteria for KPI Selection in Higher Education
Authors: Elhadjamor Emna Ammar , Ghannouchi Sonia Ayachi
Published: January 2022

Identifying and choosing the most pertinent Key Performance Indicators (KPIs) has a crucial impact on decision making: if the wrong KPIs are measured, or if they are measured in the wrong way, the information may be misleading and the quality of decisions can be significantly affected. Choosing appropriate KPIs requires a deep understanding of the organization. Moreover, a successful selection of appropriate KPIs relies on a number of well-defined criteria. We propose in this paper a new approach to facilitate the structuring, and/or synthesis of a set of specific, measurable, attainable, realistic and timebased KPIs (SMART KPIs) based on the Analytic Hierarchy Process (AHP) method. The approach steps are illustrated and validated with a real case study. This case study is related to the candidates’ selection process in a Tunisian higher education institute.
Students' Responses to Learning Management Systems in a Blended Learning Context
Authors: Attuquayefio Samuel NiiBoi
Published: January 2022

The purpose of this study is to examine first-year students’ behaviour towards learning management systems in a blended learning environment. The study employed a convenient sampling technique for data collection and SmartPLS3 was used to analyse the data. There were 671 first-year students from the University of Professional Studies Accra who participated in the survey. The findings of the study revealed that social influence, price value and anxiety significantly influence behavioural intention to use learning management systems (LMS). However, the relationship between anxiety and behavioural intention is inverse. Furthermore, anxiety significantly impacts effort expectancy, while effort expectancy also impacts satisfaction. Additionally, the results suggest that satisfaction fully mediates the relationship between effort expectancy and behavioural intention to use LMS. Administrators of higher education must ensure that the performance of the LMS exceeds the expectations of students so as to formulate the intention to use it for learning.
The Post-COVID-19 Impact on Distance Learning for New Zealand Teachers
Authors: Parsons David , Gander Tim , Baker Karen , Vo Darcy
Published: January 2022

This article reports on a survey of New Zealand teachers, designed to assess their experiences of distance learning during the COVID-19 lockdowns. The survey gathered detailed quantitative and qualitative data from 31 schoolteachers who had previously experienced professional development in digital learning. The questions addressed many areas of practice, including the issues faced by teachers in the move to online distance learning, the impacts on relationships with students, families, and other staff, the impacts on workload and practice, and the experience of working intensively with digital technologies. The results suggested that this group of relatively well-prepared teachers were able to effectively move their practice online in a short period of time and, in most cases, to maintain the relationships with, and the learning of, their students. However, there were some indications in the data that learners from the Māori community faced resource challenges in successfully transitioning to online distance learning.

This study explored the impact of the Covid-19 pandemic on the academic quality of a Foundation in Engineering programme. A Course Experience Questionnaire (CEQ) was administered before and during the pandemic to evaluate the six dimensions of academic quality – assessment, workload, teaching, academic environment, standards, and skills development. A total of 234 students participated in the study and the findings revealed that course satisfaction decreased during the pandemic. Many students were not satisfied with the teaching quality and skills development of the emergency online learning. On the contrary, students rated online assessment (during COVID-19) positively for being more appropriate in testing higher order thinking skills. The study suggested that online classes lack formal and informal social interactions to enhance various facets of skills development. Given the limitations of emergency online learning, the future of education might include moving towards blended learning.

The loess produced in South Korea is an eco-friendly material with high gas adsorption performance. Korean loess, however, cannot be used as a structural material because it has a very low compressive strength compared to cement. However, even if it is recommended as an interior material, its large drying shrinkage during drying disturbs wet construction. Therefore, this study aimed to develop a method to reduce the amount of water added while maintaining the consistency required for the plastering work of Korean loess. The experimental results showed that the dispersion of clay particles was improved when Na+ and K+, which are monovalent cations, were added to the loess colloid; the reverse occurred, i.e., aggregation of clay particles, when Ca2+ and Mg2+, which are divalent cations, were added. In addition, the dispersion and aggregation of clay particles affect the consistency of loess. The dispersion allows the loess paste to obtain the required consistency using less water, but the aggregation may exhibit the opposite effect. Accordingly, based on the same consistency, the specimens with less water exhibited less drying shrinkage. The drying shrinkage decreased by 9.23% for the specimen fabricated with the 0.01 M Na2SiO3 aqueous solution.

As a non-destructive evaluation method for friction stir welded joints, this research aims to develop and corroborate a method for material flow analysis and defect detection based on X-ray computed tomography (X-ray CT). Using a cylindrical FSW tool with a broad shoulder, joints of dissimilar materials AA6061-T6/AZ31b are friction welded employing tool rotary speed ranging from 1000 to 1500 RPM and tool feed from 125 to 400 mm/min. The welded joints are scanned via X-Ray CT with an image bit depth of 16-bit then segmented based on the Hounsfield Units scale (HU) and the global Otsu thresholding method. This segmentation divides the DICOM images into masks for each different material, from which 3D renderings are generated to record volumetric data. For analyzing elemental mixing, measurements of material penetration and transfer are carried out. Corroborating these results was accomplished using destructive cross-sectioning and Energy Dispersive X-ray Spectroscopy (EDX). The results show that this method can detect internal defects and characterize the material mixing with results comparable to that of destructive EDX analysis. The effect of improving scan resolution on reconstructed images was shown to slightly improve the accuracy of the thresholding method while reducing the standard deviation of segmented material ranges.

During a world-wide pandemic solutions for the production of anti-viral products is an at all-time high, motivating research into a wide array of potential solutions, with special interest to those capable of being deployed with as close to zero alterations to the production methods. The present work investigates the potential of using two additives, a commercially available masterbatch and a copper oxide powder, compounded using LDPE as a matrix, to be incorporated in a standard industrial setting. The final products were conventional polyester-based TNTs with 5 g m-2 coatings obtained from the micronized LDPE compounds. Antimicrobial and antiviral properties were evaluated for the two TNT products, revealing both solutions as technical equivalents and capable solutions for the production of PPEs.

The aim of this work is a development and characterization of a sustainable product from solid waste from civil construction. Morphology of collected waste has been analyzed by SEM/EDS. Residues have been macerated, mixed in different proportions with cement and water, and made into rectangular boxes. Mechanical test has been carried out by flexing three points on specimens, absorbing water and analyzing fracture by SEM. Morphology of samples have shown a heterogeneous and porous mass, with particles of different sizes, few agglomerates, and presence of organic material. Resistance to average rupture of samples has been obtained in MPa, characteristic of concrete for structural application. For CDR to be used in sustainable ceramics, it is recommended to improve a process of comminution and homogenization to guarantee reproducibility of lots and technological product properties. This being so, a mockup has been developed proposing a hollow element type product, Cobogó style, indicating potential of using civil construction waste as a sustainable product.

Influx of activated neutrophils into the lungs is the histopathologic hallmark of acute lung injury (ALI) after intestinal ischemia/reperfusion (I/R). Neutrophils can release DNA and granular proteins to form cytotoxic neutrophil extracellular traps (NETs), which promotes bystander tissue injury. However, whether NETs are responsible for the remote ALI after intestinal I/R and the mechanisms underlying the dissemination of harmful gut-derived mediators to the lungs are unknown. In the C57BL/6J mouse intestinal I/R model, DNase I–mediated degradation and protein arginine deiminase 4 (PAD4) inhibitor–mediated inhibition of NET treatments reduced NET formation, tissue inflammation, and pathological injury in the lung. High-mobility group protein B1 (HMGB1) blocking prevented NET formation and protected against tissue inflammation, as well as reduced cell apoptosis and improved survival rate. Moreover, recombinant human HMGB1 administration further drives NETs and concurrent tissue toxic injury, which in turn can be reversed by neutrophil deletion via anti-Ly6G Ab i.p. injection. Furthermore, global MyD88 deficiency regulated NET formation and alleviated the development of ALI induced by intestinal I/R. Thus, HMGB1 released from necroptotic enterocytes caused ALI after intestinal I/R by inducing NET formation. Targeting NETosis and the HMGB1 pathway might extend effective therapeutic strategies to minimize intestinal I/R-induced ALI.

Background:

The pathophysiology of an atherosclerotic plaque is mediated by the mechanisms involving thrombus formation and systemic inflammation. While C-reactive protein (CRP) levels are useful in predicting a cardiovascular event in intermediate risk population, the usefulness of routinely measuring fibrinogen in patients with acute coronary syndrome (ACS) is debatable. Also, data on the association of these markers with periprocedural outcomes in patients undergoing percutaneous coronary interventions (PCI) is scarce.

Aims:

The study aimed to determine whether the levels of fibrinogen and CRP vary across the different spectra of CAD and whether they have any correlation with cardiac Troponin I levels.

Materials and Methods:

A total of 284 patients with coronary artery disease undergoing percutaneous coronary intervention were included in the study. Complete blood count, serum lipid profile, serum CRP, fibrinogen, and troponin I were measured for all patients.

Results:

Patients with STEMI had significantly higher levels of CRP as compared to those with unstable angina (USA) and chronic stable angina (CSA). Patients presenting with ACS had significantly higher baseline fibrinogen as compared to those with CSA. A significant positive correlation between CRP and admission Troponin I (r = 0.50; P < 0.05) as well as fibrinogen and admission troponin I (r = 0.30; P < 0.05) was observed. The CRP levels were significantly higher in 15 patients with periprocedural MI as compared to those who did not develop periprocedural MI.

Conclusions:

The levels of the markers of inflammation and atherothrombosis vary with presentation across varied spectra of CAD with generally higher levels in acute presentation and in those who develop periprocedural MI.
