Cell-blocks and hematolymphoid lesions
Authors: Alrajjal Ahmed , Choudhury Moumita , Yang Jay , Gabali Ali
Published: March 2021

Cell-blocks are an important component for evaluation for hematolymphoid lesions. They are especially critical for immunocharacterization of the lymphoid population especially when flow cytometry is not available or cannot be performed. In addition, cell-blocks allow various molecular pathology tests including gene rearrangement studies and FISH, proteomics analysis, and microbiology/histochemical special stains. Fine-needle aspiration (FNA) for mass lesions, lymphadenopathy, and effusion fluids are common cytopathology specimens which are frequently cell-blocked. The differential diagnosis of enlarged lymph nodes (LNs) and mass lesions is broad and includes reactive processes, granulomatous lesions and malignancies including solid tumor metastases and various types of hematological malignancies, of which lymphoma would be most common. Depending on the patient population, most lymphomas may be diagnosed with immunocharacterization on cell-block or/and flow cytometry in concert with excellent cytomorphology in Diff-Quik stained FNA aspirate smears. However, a proportion of lymphoma cases (up to 12-30%) may still require an excisional LN biopsy to evaluate architectural parameters. Similarly, various effusion fluids suspicious for lymphoma can be immunocharacterized by immunostaining of cell-block sections (or/and by flow cytometry). Availability of quantitatively and qualitatively optimum cell-blocks of specimens to be evaluated for hematolymphoid processes is critical for immunohistochemistry, polymerase chain reaction,in situhybridization (FISH), and gene expression profiling studies.

Published: March 2021

Objectives:

The purpose of the study was to detect the presence of viral ribonucleic acid of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in conjunctival swab along with nasopharyngeal swab specimens of Coronavirus disease 2019 (COVID-19) patients.

Material and Methods:

Thirty COVID-19 patients with at least one sample positive for real-time reverse transcription-polymerase chain reaction for SARS-CoV-2 in nasopharyngeal swab with the presence or absence of ocular manifestations were included in the study. The conjunctival swab along with nasopharyngeal swab of each patient was collected and sent to microbiology lab for evaluation and analysis of viral nucleic acid to assess the viral load.

Results:

Out of 30 patients, 21 patients (70%) were males and the remaining nine patients (30%) were females. Mean age of the patients in the study was 44.80 ± 15.37 years. One patient had conjunctivitis as ocular manifestation. Two (6.7%) out of 30 patients were positive for RT-PCR SARS-CoV-2 in the conjunctival swab. There was no statistical correlation between nasopharyngeal swab and conjunctival swab positivity using Pearson’s correlation coefficient (r) = 0.010; P = 0.995 (>0.05).

Conclusion:

The results of the study revealed that SARS-CoV-2 can also be detected in conjunctival swabs of confirmed cases of COVID-19 patients. Although, in comparison to nasopharyngeal and throat swabs the rate of detection of SARS-CoV-2 in conjunctival swabs is relatively less, still diligent care and precautions should be practiced during the ophthalmic evaluation of COVID-19 patients.

Published: March 2021

Piper betle L. or Sireh is popular among the Malaysian locals and has been extensively used in traditional medicines across Asian and Southeast Asian countries. P. betle  is used to enhance the dental health and treat diseases such as rheumatism and bronchitis, though the data on the quality and safety of this plant are still limited. This study evaluated the microbiological quality and the phytochemical properties of P. betle. Bacteria and fungi were only detected following 3 months of storage duration, however, the microbial loads are within the acceptable range and the identified bacterial species were non-pathogenic. There were no significant differences (p > 0.05) between microbial enumerations data and storage duration. Three phytochemical constituents, which were saponins, tannins, and steroids, were detected in P. betle. These findings highlighted that P. betle  has  low microbial contaminants at least up to 6-months of storage, and with its phytochemical constituents preserved throughout the storage duration, it is thus safe for consumption as it is.

Published: March 2021

Antibiotic resistance has become a global issue and has had a disastrous impact, increasing patients’ morbidity and mortality. Biofilm formation is one of the factors contributing to bacterial resistance against many antibiotics. As one of the world’s richest sources of plant biodiversity, Indonesia has the potential to develop its natural resources as raw material for medicine. Atuna racemosa Raf. is a native Indonesian plant, that belongs to the Chrysobalanaceae family and grows abundantly in the Maluku Islands. It is widely used in Ambon as cooking spice and massage oil, as well as to treat inflammation including fever, leg inflammation, and diarrhea. Many recent studies have conducted botanical investigations regarding the potential of Atuna racemosa Raf. as a potent antibacterial agent. Many active compounds are found in Atuna racemosa Raf., such as 4'-O-methyl-ent-gallocathechin and (+)-gallocatechin, which are known to be effective against antibiotic-resistant bacteria, namely Methicillin-resistant Staphylococcus aureus (MRSA). Atun plants also contain several types of phytochemical components in which additional antibacterial activity was discovered. Accordingly, Atun has the potential to be developed as an alternative antibacterial and antibiofilm source. This narrative review aimed to identify the potential of the Atuna racemosa Raf. Plant as a source of antibacterial and antibiofilm agents, the phytochemical components, and its various extracts, as well as its active compounds. This review is expected to contribute to the discovery of a novel antibacterial and antibiofilm source which is safe and effective, in the context of utilizing Indonesia's biodiversity.

Published: March 2021

Antibiotic resistance is considered a grievous danger to the well-being of common people owing to the growing trend of prescribing antibiotics. In reality, this threat is suitably referred to as a “ticking time bomb” necessitating quick interventions. Antibiotic resistance is not entirely recognized worldwide but is seen to affect poorer countries with inadequate and weaker healthcare systems. Regrettably, dentists still continue prescribing antibiotics to patients with an endodontic cause such as periapical abscesses & irreversible pulpitis, which requires only operative procedures. When we talk about the endodontic cause, antibiotics are prescribed widely systemically and locally as well. Intracanal medicaments, irrigant containing antibiotics, medicated sealer & medicated gutta percha comprises of the local mode of taking antibiotics, which enables dentist in aiming microorganisms in every single crook & bend of a root canal, which remains unreachable if done by usual RCT protocols. Instead of using Triple antibiotic paste in patients, to avoid antimicrobial resistance, calcium hydroxide can also be added. The fundamental base for substantial endodontic treatment comprises of complete debridement of the root canals which are infected along with drainage of hard and soft tissues. Even after achieving adequate debridement & drainage, the literature showed that prescribing antibiotics collaterally did not show any added therapeutic effect in preventing or resolving the signs & symptoms occurring during an endodontic infection. The objective of this current article is to comment about the over usage of antibiotics before and during endodontic management, its impact on antibiotic resistance, and crucial methods needed to prevent and manage the antibiotic abuse during endodontic treatment.

Published: March 2021

The article aims to generalize the information on the Neolithic sites of the Baikal coast identified for all period of the research, to evaluate their significance and prospects for further study. It is based on literary, archival materials and the results of our own field work. A list of objects (93 sites) was determined, their mapping was done, preliminary dating was clarified, data on radiocarbon dates ware collected (48 dates for 12 sites). Among the Neolithic objects, microlayered sites containing pure complexes of this time are the most important. 34 such objects have been recorded along the entire coast of Lake Baikal. Excavations were carried out on 17 of them, the rest of the sites were revealed by small excavation works. Approximately a third of objects (29 sites) are identified based on the collection of exposed material. A significant group is represented by macrolayered objects (30 sites), where the Neolithic materials are in a situation of compression with the complexes of other chronological periods. The unevenness of the archaeological study of the Baikal shore is noted. The Cis-Olkhon region has the greatest scientific potential. 10 microlayered sites (out of 22) were comprehensively excavated on this territory. Enough reliable stratigraphy, geological and geomorphological characteristics, qualitative, informative archaeological material, and the series of radiocarbon dates were obtained. The southwestern Baikal shore sites (3 out of 7 microlayered objects have been excavated) and Chivyrkui Bay (1 out of 3 objects) represented a promising material. These archaeological sites are a reliable source base and pivotal in the study of the regional Neolithic. At present, the largest number of sites with complexes of the Early (16 sites) and Late (13 sites) Neolithic have been identified on the Baikal coast. Complexes of the Middle Neolithic in microlayered position are noted at 6 sites. The complexes of the Cis-Olkhon region and the southwestern Baikal coast are provided with radiocarbon dates. For the Late Neolithic there are 25 reliable dates, for the Early Neolithic – 19 dates, for the Middle Neolithic – 4 dates. According to them, the complexes of the Early Neolithic are dated in the range of 7214–6123 BP (8160–6910 cal BP), Middle Neolithic – 5874–5597 BP (6750–6310 cal BP), Late Neolithic – 4967–4217 BP (5840–4630 cal BP). In general, the Neolithic sites of the Baikal coast have great scientific potential and prospects for future research.

Published: March 2021

Use of cannabis for recreational, religious and cultures has been prevalent since ancient times. It is one of the commonest used illicit substance. While not all cannabis users develop psychiatric problems, heavy cannabis use may increase the risk of cognitive abnormalities, psychotic illness and mood disorders. This research aimed to evaluate severity of various psychotic symptoms in relation to variables of cannabis abuse. A cross sectional study of 30 male patients admitted at tertiary care psychiatric center with diagnosis of cannabis-associated psychosis was carried out. Cannabis abuse variables along with psychotic symptoms severity on BPRS scale were obtained. Correlation between variables of cannabis abuse and psychotic symptoms and total BPRS score were derived using Pearson correlation 2- tailed test. Hostility (83%) and excitement (77%) were most prevalent symptoms with increased severity followed by elevated mood, grandiosity, suspiciousness and motor hyperactivity. Patients with long duration and early onset of cannabis abuse presented with more severe form of psychosis. Frequency of cannabis use was not significantly correlated with total BPRS score, although amount spent over cannabis was significantly associated with total BPRS score. Family history of cannabis abuse predicted early onset of cannabis abuse.

Automated heuristic design using genetic programming hyper-heuristic for uncertain capacitated arc routing problem
Authors: Liu Yuxin , Mei Yi , Zhang Mengjie , Zhang Zili
Published: March 2021

Uncertain Capacitated Arc Routing Problem (UCARP) is a variant of the well-known CARP. It considers a variety of stochastic factors to reflect the reality where the exact information such as the actual task demand and accessibilities of edges are unknown in advance. Existing works focus on obtaining a robust solution beforehand. However, it is also important to design effective heuristics to adjust the solution in real time. In this paper, we develop a new Genetic Programming-based Hyper-Heuristic (GPHH) for automated heuristic design for UCARP. A novel effective meta-algorithm is designed carefully to address the failures caused by the environment change. In addition, it employs domain knowledge to filter some infeasible candidate tasks for the heuristic function. The experimental results show that the proposed GPHH significantly out performs the existing GPHH methods and manually designed heuristics. Moreover, we find that eliminating the infeasible and distant tasks in advance can reduce much noise and improve the efficacy of the evolved heuristics. In addition, it is found that simply adding a slack factor to the expected task demand may not improve the performance of the GPHH.

Efficient meta-heuristics for the multi-objective time-dependent orienteering problem
Authors: Mei Yi , Salim Flora D , Li Xiaodong
Published: March 2021

In this paper, the Multi-Objective Time-Dependent Orienteering Problem (MOTDOP) is investigated. Time-dependent travel time and multiple preferences are two of the most important factors in practice, and have been handled separately in previous work. However, no attempts have been made so far to consider these two factors together. Handling both multiple preferences and time-dependent travel time simultaneously poses a challenging optimization task in this NP-hard problem. In this study, two meta-heuristic methods are proposed for solving MOTDOP: a Multi-Objective Memetic Algorithm (MOMA) and a Multi-objective Ant Colony System (MACS). Two sets of benchmark instances were generated to evaluate the proposed algorithms. The experimental studies show that both MOMA and MACS managed to find better solutions than an existing multi-objective evolutionary algorithm (FMOEA). Additionally, MOMA achieved better performance than MACS in a shorter time, and is less sensitive to the parameter setting. Given that MACS inherits promising features of P-ACO, which is a state-of-the-art algorithm for multi-objective orienteering problem, the advantage of MOMA over MACS and FMOEA demonstrates the efficacy of adopting the memetic algorithm framework to solve MOTDOP.

Feature selection in evolving job shop dispatching rules with genetic programming
Authors: Mei Yi , Zhang Mengjie , Nyugen Su
Published: March 2021

Genetic Programming (GP) has been successfully used to automatically design dispatching rules in job shop scheduling. The goal of GP is to evolve a priority function that will be used to order the waiting jobs at each decision point, and decide the next job to be processed. To this end, the proper terminals (i.e. job shop features) have to be decided. When evolving the priority function, various job shop features can be included in the terminal set. However, not all the features are helpful, and some features are irrelevant to the rule. Including irrelevant features into the terminal set enlarges the search space, and makes it harder to achieve promising areas. Thus, it is important to identify the important features and remove the irrelevant ones to improve the GP-evolved rules. This paper proposes a domain-knowledge-free feature ranking and selection approach. As a result, the terminal set is significantly reduced and only the most important features are selected. The experimental results show that using only the selected features can lead to significantly better GP-evolved rules on both training and unseen test instances.

Memetic algorithm with route decomposing for periodic capacitated arc routing problem
Authors: Zhang Yuzhou , Mei Yi , Tang Ke , Jiang Keqin
Published: March 2021

In this paper, the Periodic Capacitated Arc Routing Problem (PCARP) is investigated. PCARP is an extension of the well-known CARP from a single period to a multi-period horizon. In PCARP, two objectives are to be minimized. One is the number of required vehicles (nv), and the other is the total cost (tc). Due to the multi-period nature, given the same graph or road network, PCARP can have a much larger solution space than the single-period CARP counterpart. Furthermore, PCARP consists of an additional allocation sub-problem (of the days to serve the arcs), which is interdependent with the routing sub-problem. Although some attempts have been made for solving PCARP, more investigations are yet to be done to further improve their performance especially on large-scale problem instances. It has been shown that optimizing nv and tc separately (hierarchically) is a good way of dealing with the two objectives. In this paper, we further improve this strategy and propose a new Route Decomposition (RD) operator thereby. Then, the RD operator is integrated into a Memetic Algorithm (MA) framework for PCARP, in which novel crossover and local search operators are designed accordingly. In addition, to improve the search efficiency, a hybridized initialization is employed to generate an initial population consisting of both heuristic and random individuals. The MA with RD (MARD) was evaluated and compared with the state-of-the-art approaches on two benchmark sets of PCARP instances and a large data set which is based on a real-world road network. The experimental results suggest that MARD outperforms the compared state-of-the-art algorithms, and improves most of the best-known solutions. The advantage of MARD becomes more obvious when the problem size increases. Thus, MARD is particularly effective in solving large-scale PCARP instances. Moreover, the efficacy of the proposed RD operator in MARD has been empirically verified.

MODELING OF NEURAL PREDICTIVE CONTROL OF IRRIGATION MACHINES
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, KAMYSHOVA G. N.
Published: March 2021

The purpose of the study is to develop new scientific approaches to improve the efficiency of irrigation machines. Modern digital technologies allow the collection of data, their analysis and operational management of equipment and technological processes, often in real time. All this allows, on the one hand, applying new approaches to modeling technical systems and processes (the so-called “data-driven models”), on the other hand, it requires the development of fundamentally new models, which will be based on the methods of artificial intelligence (artificial neural networks, fuzzy logic, machine learning algorithms and etc.).The analysis of the tracks and the actual speeds of the irrigation machines in real time showed their significant deviations in the range from the specified speed, which leads to a deterioration in the irrigation parameters. We have developed an irrigation machine’s control model based on predictive control approaches and the theory of artificial neural networks. Application of the model makes it possible to implement control algorithms with predicting the response of the irrigation machine to the control signal. A diagram of an algorithm for constructing predictive control, a structure of a neuroregulator and tools for its synthesis using modern software are proposed. The versatility of the model makes it possible to use it both to improve the efficiency of management of existing irrigation machines and to develop new ones with integrated intelligent control systems.

Published: March 2021

The prospects for the use of solar power plants in the world of environmental hydraulic engineering are analyzed. Recommendations on the constructive combination of elements of structures of environmental hydro technical complexes with solar photovoltaic installations (SFEU) are presented. The variants of their most rational location on the building of hydroelectric power stations (GES) of different types are considered. It is established that the buildings of small and medium-sized hydroelectric power plants represent significantly more constructive possibilities for combining the GES building with the SFEU. The relationship between the area suitable for placing solar cells and the diameter of the turbine impeller is determined. With a decrease in the diameter of the impeller, the relative surface area suitable for placing solar cells increases. It is noted that it is most appropriate to combine SFEU and small hydroelectric power plants with non-combined buildings with transformers on the downstream side. At medium-sized hydroelectric power plants of various types, the conditions for combining are approximately the same. The results of the work can have an impact on obtaining a reliable power supply system based on renewable energy sources, improving the safety of the GTS (hydro technical structures) of existing hydroelectric facilities in the context of increasing the efficiency of the introduction of ”green“ technologies in the energy sector while reducing biosphere pollution and greenhouse gas emissions, including in hard-to-reach areas of agricultural areas where there are problems with centralized water supply.

The need to create a single unified information and diagnostic system to ensure the safe operation of hydraulic structures is caused by the requirements of the Federal Law ”On the safety of hydraulic structures“ (No. 117-FZ). At the current moment, the systems used are heterogeneous and are being developed according to the requirements of operation and expert organizations, while the uniformity of terminology and approach to assessing the state of objects is not ensured. The purpose of this work is to define approaches and to develop architecture for a unified information and diagnostic system. At the same time, it is necessary to ensure the performance of the minimum set of functions necessary for a comprehensive analysis of the state of hydraulic structures. There is given a description of the architecture and basic set of functions of the information system which make it possible to monitor the state of hydraulic structures. The systematization of the functionality of the existing information systems has been carried out, on the basis of the analysis the optimal composition of the minimum number of functions which provide control over the safe operation of hydraulic structures has been developed.
European Banking Union – an institutional analysis
Authors: Majewska-Jurczyk Barbara
Published: March 2021

Aim: The Banking Union is an important step towards a genuine Economic and Monetary Union. The strengthening of the European banking system has become a topic of debate since the 2008 crisis when it became clear that stability and security of the system security may require increased supervision over operations conducted. The Banking Union was created to avoid the situation that taxpayers are first in line to pay for bailing out ailing banks. The Banking Union consists of three pillars: 1) the Single Supervisory Mechanism (SSM), which centralizes supervision of European banks around the European Central Bank, 2) the Single Resolution Mechanism (SRM), which the main purpose is to ensure the efficient resolution for recapitalization failing banks, and 3) the European Deposit Insurance Scheme (EDIS), which is still unfinished. The creation of the Banking Union is accompanied by a remarkable transfer of sovereignty to the European level. This article aims to provide an overview of the changes unfolding across the Banking Union from a law and economics perspective and to explain the role of the European Central Bank in supervision over the banking system, which is different from the policy of controlling prices through determining the level of interest rates and keeping inflation under control.

 

Design/Research methods: The analysis of the functioning Banking Union is based on the review of literature and analysis of reports and legal acts.

 

Findings: The Banking Union supports financial integration in the EU by implementing a common set of rules and a common supervisory and resolution mechanism. The creation of the Deposit Insurance Scheme is likely to contribute to the protection of banks and consumers in case of a potential future crisis. The author argues that the European Central Bank as a supervisor of the financial market should create a second supervisory body, which would significantly strengthen the system and allow the ECB more efficiently fulfill its task as chief supervisor.
