Authors: Dachev Marko , Bryndová Jana , Jakubek Milan , Moučka Zdeněk , Urban Marian
Published: March 2021

Conjugated linoleic acids (CLA) are distinctive polyunsaturated fatty acids. They are present in food produced by ruminant animals and they are accumulated in seeds of certain plants. These naturally occurring substances have demonstrated to have anti-carcinogenic activity. Their potential effect to inhibit cancer has been shown in vivo and in vitro studies. In this review, we present the multiple effects of CLA isomers on cancer development such as anti-tumor efficiency, anti-mutagenic and anti-oxidant activity. Although the majority of the studies in vivo and in vitro summarized in this review have demonstrated beneficial effects of CLA on the proliferation and apoptosis of tumor cells, further experimental work is needed to estimate the true value of CLA as a real anti-cancer agent.

Breast cancer is the most common neoplasm and the leading cause of cancer death in women worldwide. Although 5-fluorouracil is a conventional chemotherapeutic agent for breast cancer treatment, its use may result in severe side effects. Thus, there is widespread interest in lowering 5-fluorouracil drawbacks, without affecting its therapeutic efficacy by the concomitant use with natural products. Herein, we aimed at evaluating whether α-mangostin, a natural antineoplastic compound, could increase the anticancer effect of 5-fluorouracil in different breast cancer cell lines, allowing for dose reduction. Cell proliferation was evaluated by sulforhodamine-B assays, inhibitory concentrations and potency were calculated by dose-response curves, followed by analysis of their pharmacological interaction by the combination-index method and dose-reduction index. Cell cycle distribution was evaluated by flow cytometry. Each compound inhibited cell proliferation in a dose-dependent manner, the triple negative breast cancer cells being the most sensitive. When 5-fluorouracil and α-mangostin were used concomitantly, synergistic antiproliferative effect was observed. The calculated dose-reduction index suggested that this combination exhibits therapeutic potential for reducing 5-fluorouracil dosage in breast cancer. Mechanistically, the cotreatment induced cell death in a greater extent than each drug alone. Therefore, α-mangostin could be used as a potent co-adjuvant for 5-fluorouracil in breast cancer.

Meat is often wasted due to the perceived concerns of its shelf life and preservation. Specifically, in meat formation, biogenic amines (BAs) are the major agents to spoil them. Herein, we have developed a carbon disulfide (CS2) added colloidal gold nanoparticles-based colorimetric sensor for the rapid and on-site detection of biogenic amines. Transmission electron microscopy is used to observe the morphological changes in colloidal gold nanoparticles and aggregation behavior of CS2 added to the colloidal gold nanoparticles’ solution. Raman spectroscopic analysis is further used to characterize the peaks of CS2, Cad and CS2-Cad molecules. Absorption spectroscopy is used to estimate the colorimetric differences and diffuse reflectance spectra of the samples. The sensing analysis is performed systematically in the presence and absence of CS2. CS2 added colloidal gold nanoparticles colorimetric sensor detected the BAs with a limit of detection (LOD) value of 50.00 µM. Furthermore, the developed sensor has shown an LOD of 50.00 µM for the detection of multiple BAs at a single time. The observed differences in the colorimetric and absorption signals indicate that the structure of BAs is converted to the dithiocarbamate (DTC)-BA molecule, due to the chemical reactions between the amine groups of BAs and CS2. Significantly, the developed colorimetric sensor offers distinct features such as facile fabrication approach, on-site sensing strategy, rapid analysis, visual detection, cost-effective, possibility of mass production, availability to detect multiple BAs at a single time and appreciable sensitivity. The developed sensor can be effectively used as a promising and alternative on-site tool for the estimation of BAs.
Application of Optimization Algorithms for Identification of Reference Points in a Monitoring Network
Authors: Odziemczyk Waldemar
Published: March 2021

Geodetic measurements are commonly used in displacement analysis to determine the absolute values of displacements of points of interest. In order to properly determine the displacement values, it is necessary to correctly identify a subgroup of mutually stable points constituting a reference system. The complexity of this task depends on the spatial size of the network, the timespan of measurements and geological conditions affecting the type of changes in the location of points. As a consequence of the abovementioned factors, the task of stable identification in a longer timespan for a subgroup of points may produce equivocal results. In particular, it is likely that alternative subgroups of reference points meeting the mutual stability criteria will be selected, sometimes without common reference points. The proposed method of reference system identification utilises optimisation algorithms. Two such algorithms were tested, i.e., simulated annealing (SA) and Hooke-Jeeves (HJ) method. Two numerical examples were used to test the proposed method. Although in the first example both methods delivered a positive result, the second example showed the superiority of the SA method over the HJ. The proposed method can be considered a tool supporting the person analysing and making calculations in reaching the ultimate decision on reference points.
Comparison of the Performance of the Leap Motion ControllerTM with a Standard Marker-Based Motion Capture System
Authors: Ganguly Amartya , Rashidi Gabriel , Mombaur Katja
Published: March 2021

Over the last few years, the Leap Motion Controller™ (LMC) has been increasingly used in clinical environments to track hand, wrist and forearm positions as an alternative to the gold-standard motion capture systems. Since the LMC is marker-less, portable, easy-to-use and low-cost, it is rapidly being adopted in healthcare services. This paper demonstrates the comparison of finger kinematic data between the LMC and a gold-standard marker-based motion capture system, Qualisys Track Manager (QTM). Both systems were time synchronised, and the participants performed abduction/adduction of the thumb and flexion/extension movements of all fingers. The LMC and QTM were compared in both static measuring finger segment lengths and dynamic flexion movements of all fingers. A Bland–Altman plot was used to demonstrate the performance of the LMC versus QTM with Pearson’s correlation (r) to demonstrate trends in the data. Only the proximal interphalangeal joint (PIP) joint of the middle and ring finger during flexion/extension demonstrated acceptable agreement (r = 0.9062; r = 0.8978), but with a high mean bias. In conclusion, the study shows that currently, the LMC is not suitable to replace gold-standard motion capture systems in clinical settings. Further studies should be conducted to validate the performance of the LMC as it is updated and upgraded.
A Lightweight 1-D Convolution Augmented Transformer with Metric Learning for Hyperspectral Image Classification
Authors: Hu Xiang , Yang Wenjing , Wen Hao , Liu Yu , Peng Yuanxi
Published: March 2021

Hyperspectral image (HSI) classification is the subject of intense research in remote sensing. The tremendous success of deep learning in computer vision has recently sparked the interest in applying deep learning in hyperspectral image classification. However, most deep learning methods for hyperspectral image classification are based on convolutional neural networks (CNN). Those methods require heavy GPU memory resources and run time. Recently, another deep learning model, the transformer, has been applied for image recognition, and the study result demonstrates the great potential of the transformer network for computer vision tasks. In this paper, we propose a model for hyperspectral image classification based on the transformer, which is widely used in natural language processing. Besides, we believe we are the first to combine the metric learning and the transformer model in hyperspectral image classification. Moreover, to improve the model classification performance when the available training samples are limited, we use the 1-D convolution and Mish activation function. The experimental results on three widely used hyperspectral image data sets demonstrate the proposed model’s advantages in accuracy, GPU memory cost, and running time.
Education for Sustainable Development and Children’s Involvement in Public Spaces. From Universalism to Places, from Rights to Capabilities: Some Evidence from a Research Project on the Regeneration of Public Spaces in Milan
Authors: Pippa Stefano , Malatesta Stefano , De Michele Cristina , Biffi Elisabetta
Published: March 2021

The United Nations Decade on Education for Sustainable Development (ESD) expanded the epistemological and methodological debate on sustainability and education. Currently, ESD encompasses a broad spectrum of socio-political issues (including global citizenship and social justice), while “place-bonding” is seen as key to fostering citizen advocacy in local communities and enhancing “children’s lived experiences of local issues”. Herein, we emphasize both the political and the pedagogical value of this perspective, arguing that ESD bears the potential to overcome “universal vs. individual” tensions and dichotomies. Our line of reasoning is that the “capabilities approach” (CA), although it did not originally focus on children, can offer a useful theoretical framework in support of ESD, thanks to its multidimensional nature and focus on the concrete agency of individuals. Accordingly, we see the CA as playing a key role in bridging the gap between universal prescriptions, which disregard the specificity of the actors involved, as well as the peculiar nature of their social environment and its context-specific needs or constraints. We supplement this theoretical discussion by presenting “The Flying Carpet”, an ongoing community-based education project that has elicited the active involvement of over one hundred 11–13 year old students in an urban regeneration project in a municipal district of Milan.
Demographics of Sudanese University Students in Relation to Regional Conflict and Underdevelopment
Authors: Hamid Monira , Thron Christopher , Fageeri Sallam
Published: March 2021

This research examines regional differences in higher education participation rates in Sudan, and their relations with socioeconomic factors related to development, such as human development index (HDI), women’s status, urban/rural, and source of income. We pay special attention to areas of Sudan where long-running conflicts exist. Two datasets are used: the 2009 National Baseline Household Survey, conducted by Sudan’s Central Bureau of Statistics; and 2016–2017 matriculating students’ data, obtained from Sudan’s Ministry of Education. Regression analysis of the household survey data shows that the most significant factors associated with university attendance are having electricity at home, having a mother who has completed primary education, and being from a non-conflict region. University entrance data shows that young adults from conflict regions lag markedly behind the rest of Sudan in entering students’ academic level. Educational resources in Sudan are densely concentrated in the capital Khartoum, and higher-performing students (especially males) from all regions tend to enroll in universities in Khartoum. Regional universities’ student bodies consist largely of lower-performing students from the same region, especially in conflict regions. Women’s participation in higher education is robust, and women bachelor’s students outnumber men. Our analysis suggests that the following policies could be most effective in improving regional higher education enrollment rates and outcomes: (1) improve infrastructure (electric power in particular) in underserved regions; (2) provide widespread primary education for women; (3) put additional resources into regional universities, to encourage geographical diversity and to better serve women in underdeveloped regions.

The ever-increasing complexity of cyber-physical systems is driving the need for assurance of critical infrastructure and embedded systems. However, traditional methods to secure cyber-physical systems—e.g., using cyber best practices, adapting mechanisms from information technology systems, and penetration testing followed by patching—are becoming ineffective. This paper describes, in detail, Verification Evidence and Resilient Design In anticipation of Cybersecurity Threats (VERDICT), a language and framework to address cyber resiliency. When we use the term resiliency, we mean hardening a system such that it anticipates and withstands attacks. VERDICT analyzes a system in the face of cyber threats and recommends design improvements that can be applied early in the system engineering process. This is done in two steps: (1) Analyzing at the system architectural level, with respect to cyber and safety requirements and (2) by analyzing at the component behavioral level, with respect to a set of cyber-resiliency properties. The framework consists of three parts: (1) Model-Based Architectural Analysis and Synthesis (MBAAS); (2) Assurance Case Fragments Generation (ACFG); and (3) Cyber Resiliency Verifier (CRV). The VERDICT language is an Architecture Analysis and Design Language (AADL) annex for modeling the safety and security aspects of a system’s architecture. MBAAS performs probabilistic analyses, suggests defenses to mitigate attacks, and generates attack-defense trees and fault trees as evidence of resiliency and safety. It can also synthesize optimal defense solutions—with respect to implementation costs. In addition, ACFG assembles MBAAS evidence into goal structuring notation for certification purposes. CRV analyzes behavioral aspects of the system (i.e., the design model)—modeled using the Assume-Guarantee Reasoning Environment (AGREE) annex and checked against cyber resiliency properties using the Kind 2 model checker. When a property is proved or disproved, a minimal set of vital system components responsible for the proof/disproof are identified. CRV also provides rich and localized diagnostics so the user can quickly identify problems and fix the design model. This paper describes the VERDICT language and each part of the framework in detail and includes a case study to demonstrate the effectiveness of VERDICT—in this case, a delivery drone.

Improvement of methods of diagnostics, classification of tooth enamel microfissures and of method for evaluating the effectiveness of their treatment
Authors: Zabolotnaia I.I.
Published: March 2021

In clinical practice it is often diagnosed precervical lesions: wedge-shaped defect, precervical caries and fissures. The scientific research reveals results of application of an electrometric method for diagnostics of microfissures of teeth hard tissues. Use of this method will allow not only to make a pre-clinical diagnostics of the given pathology, but also to evaluate efficiency of the taken treatment-and-prophylactic measures. 16.70 % of cases the type of dental enamel fissures diagnosed before research, depending on complexity of their revealing, mismatched the received results of width of their disclosing. So, before the preparation of precervical pathology, we recommend to classify the diagnosed enamel microfissures of vestibular surface into two types: I – fissures, which are visible after using additional lighting, drying, optical systems, diagnostic dye, determining the electrical resistance, using of transillumination and other additional methods; ІІ – fissures, which are visible to the naked eye under normal lighting condition. Application of the proposed qualification of incomplete microfissures will promote to improving the effectiveness of surgical treatment of cervical lesions of teeth hard tissues.
Schmalenbach on Standing Alone before God: A Philosophical Case-Study in Ontologico-Historical Understanding
Authors: Humphries Carl
Published: March 2021

This article explores the clarificatory potential of a specific way of approaching philosophical problems, centered on the analysis of the ways in which philosophers treat the relationship between ontological and historical forms of commitment. Its distinctive feature is a refusal to begin from any premises that might be considered “ontologistic” or “historicistic.” Instead, the relative status of the two forms of commitment is left open, to emerge in the light of more specific inquiries themselves. In this case the topic in question is furnished by an essay from the early twentieth century German philosopher Herman Schmalenbach, entitled “Der Genealogie der Einsamkeit” (somewhat problematically translated as “On Lonesomeness”). The aim is to show how the import of Schmalenbach’s historico-philosophical treatment of certain features arguably central to the spiritual practices and religious beliefs of Christianity can be more effectively grasped when approached in these terms. The first part provides an overview of the key points of Schmalenbach’s essay, while the second presents some conceptual-analytic considerations as a basis for exploring relations between ontological and historical forms of commitment as these figure in his text. Some possible broader implications for Christianity and its relationship to modern society are then also briefly sketched.

Authors: Kawase Motoki , Suda Jun
Published: March 2021

Raman spectra for longitudinal optical phonon-plasmon coupled mode in n-type GaN crystals were measured from room temperature to 200 °C by micro-Raman spectroscopy. We calculated the electron density, electron mobility, and resistivity values of the sample by spectra analysis fitting of the imaginary part of the dielectric dispersion equation to this observed mode profiles using adjustable parameters in n-type GaN at high temperatures. The calculated values of the electron density, electron mobility, and resistivity reproduced those by Hall effect measurement. The results showed that the electron density values in n-type GaN tend to increase slightly with increasing temperature while the electric mobility decreases.

Stability of ferroelectricity in hafnium–zirconium oxide (HZO) films deposited by sputtering and chemical solution deposition (CSD) has been investigated. After confirming the ferroelectricity of both sputtered HZO and CSD yttrium-doped HZO (Y-HZO) films, indium-tin-oxide (ITO) was deposited by sputtering on sputtered HZO or CSD Y-HZO layer to fabricate metal-ferroelectric-semiconductor (MFS) structure. It was found that the sputtered HZO films in the MFS structure became paraelectric after re-annealing in N2 which was confirmed by both X-ray diffraction pattern and electrical measurements. On the other hand, the CSD Y-HZO films showed ferroelectric nature even after re-annealing with a negligible monoclinic phase.

Peat soil is formed from river-bog sediments (abQ232) are largely distributed in Mekong river Delta provinces-Vietnam such as Kien Giang, Hau Giang, Bạc Liêu and Ca Mau. The resuls of research to improve them with many kinds of cements showed that the unconfined compressive strength of soil samples reinforced by cements had increased within 28 days, from 28 to 56 days this strength was reduced. Research for improving the soil above by cement and sodium silicate to increase the strength and stability with curing time had been conducted. The results showed that the concent of 0.5% of sodium silicate in comparison with cement mass was added to soil samples, their strength increased significantly when compared to soil samples without sodium silicate and greater than that of the soil samples reinforced by contents of 1%, 1.5% and 2% of sodium silicate in comparison with cement mass and also the concent of 0.5% of sodium silicate in comparison with cement mass added to soil sample has solved the problem of reducing soil sample strength with curing time.
ASST Papa Giovanni XXIII, Bergamo: a new organizational Microbiology and Virology Laboratory structure to face the health emergency from the Sars-Cov-2 outbreak.
Authors: Napolitano Gavino , Fanizzi Silvia , Cesa Simonetta
Published: March 2021

On January 12, 2020, the World Health Organization (WHO) declared Covid-19 an emergency of international interest. The first documented case in the "Pope John XXIII" Hospital in Bergamo was identified on Friday, February 21, 2020.
The ASST Pope John XXIII of Bergamo was among the very first Hospital Companies to implement a series of organizational remodelling to quickly face the health emergency from the Sars-Cov-2 outbreak.
In this context, we will describe the role and organizational changes adopted by the Complex Operating Unit (UOC) Microbiology and Virology.
Laboratory diagnostics can effectively help counteract this and other (future) viral outbreaks.
Molecular diagnostics is the only method currently recommended for the identification of infectious cases.
The gold-standard method for identifying the virus is Real-time PCR (RT-PCR) according to both the protocol of the Charitè University Hospital in Berlin and the American CDC (Center for Disease Control and Prevention). Biological samples of the lower respiratory tract (sputum, endotracheal aspirate, or broncho-alveolar washing) or alternatively upper respiratory tract samples are preferred for the execution of a swab for each nostril and a swab for each side of the oropharyngeal cavity.
The need to adopt a new organizational structure also concerned the UOC Microbiology and Virology, which was quickly called upon to cope with the health emergency by making its contribution through molecular research of the Sars-Cov-2 virus. We will illustrate the salient phases of the reorganization that led to the execution of over 1000 molecular swabs per day and the implementation of a service in H24.
Properly managing human resources in the 24 hours was essential for the proper functioning of the laboratory itself and to deal with the ongoing health emergency. In this even evolving and uncertain context, it was difficult to adopt predefined strategies, but the right involvement, the self-denial of the staff and the strong team spirit have made it possible to achieve excellent performance and quality results.
Distilling Deep Structural Facial Relationships for FAU Intensity Estimation
Authors: Fan Yingruo , Lam Jacqueline CK , Li Victor On Kwok
Published: March 2021

Facial emotions are expressed through a combination of facial muscle movements, namely, the Facial Action Units
(FAUs). FAU intensity estimation aims to estimate the intensity of a set of structurally dependent FAUs. Contrary to the existing
works that focus on improving FAU intensity estimation, this study investigates how knowledge distillation (KD) incorporated into
a training model can improve FAU intensity estimation efficiency while achieving the same level of performance. Given the intrinsic
structural characteristics of FAU, it is desirable to distill deep structural relationships, namely, DSR-FAU, using heatmap
regression. Our methodology is as follows: First, a feature map-level distillation loss was applied to ensure that the student
network and the teacher network share similar feature distributions. Second, the region-wise and channel-wise relationship
distillation loss functions were introduced to penalize the difference in structural relationships. Specifically, the region-wise
relationship can be represented by the structural correlations across the facial features, whereas the channel-wise relationship is
represented by the implicit FAU co-occurrence dependencies. Third, we compared the model performance of DSR-FAU with the
state-of-the-art models, based on two benchmarking datasets. Our proposed model achieves comparable performance with other
baseline models, though requiring a lower number of model parameters and lower computation complexities.

In the framework of the modern microbiological paradigm, colonies of genetically identical microorganisms are considered as biosocial systems consisting of several heterogeneous clonal cell clusters (bacterial phenotypes) that respond differently to changes in the environment. Phenotypic heterogeneity was found in recent decades in all isogenic populations of pathogenic bacteria. Such heterogeneity provides a selective advantage of cellular phenotypes with changes in the physicochemical parameters of the environment and competitive interaction with other microorganisms. Heterogeneity in bacterial communities is of great importance for the survival of pathogenic bacteria in the host organism, the progression and persistence of infections, as well as the decrease in the effectiveness of antibiotic therapy. The modern spectrum of analytical tools for studying cellular phenotyping is presented both by optical imaging methods and qualitative structural characteristics of single cells, and by omix technologies of quantitative analysis and monitoring of molecular intracellular processes. These diverse tools make it possible not only to identify and modulate phenotypic heterogeneity in isogenic bacterial populations, but also to evaluate the functional significance of cellular phenotypes in the development of the infectious process. The aim of the review is the integration of modern concepts of heterogeneity in isogenic bacterial populations, with an emphasis on the presentation of modern analytical technologies for assessing and monitoring phenotypic typing of single cells.

Cataract iz one of the most common eye diseases among elderly people. The crystalline lens of the human eye is like a “natural lens which skips and refractors light rays. The crystalline lens is located inside the eyeball between the iris and vitreous parts of the eye. In youth the eye’s lens is transparent, elastic, can change its shape, almost instantly directing and managing its focus, this is why an eye sees the far and near objects equally good. In case of the cataract there is partial or absolute clouding of the lens, which may lead to the loss of its transparency and the eye gets only the small amount of light rays, thus it causes the complication of vision, and the eyesight becomes unclear and blurry. Over the years, the disease progresses: the degraded part increases and eyesight completely weakens. If the disease will not be treated in time cataract may even lead to the complete blindness.

The Rabies – a viral disease characterized by severe damage of the nervous system. The analysis of data from the Rospotrebnadzor for 4 years (from 2015 to 2018) on the varmint of animals with rabies in four regions of the Central Federal District with different population densities is carried out. The main carriers of rabies virus in the region are the red fox, raccoon dog, stray dogs and cats; the role of other species is not so significant and rarely exceeds 1% of the total number of animals with suspected rabies. It has been established that in areas with a low population (Tver region) the role of a raccoon dog in rabies transfer can be even more significant than red foxes. To reduce the incidence of human rabies, constant monitoring and regulation of the numbers of foxes and raccoon dogs in the wild, as well as stray dogs and cats, is highly required. Consequently, we consider the current tendency to remove stray dogs from their habitats, their sterilization and return to urbocenosis insufficient; sterilized dogs will remain a source of rabies in populated locations.

Reducing the level of aflatoxin contamination of animal feed using soil-isolated cultures of B. subtilis, showed the prospects of using this type of bacteria for decontamination of feed. A total of 367 B. subtilis cultures were isolated from soil in southern Vietnam and screened for inhibition of aflatoxin production by Aspergillus in vitro. Of these, 34 isolates of biologically active B. subtilis were selected, of which 7 isolates were the most resistant to aflatoxin. These cultures of bacilli after 5 days of cultivation in a mixture with Aspergillus on crushed corn contributed to a 26,76-fold decrease in aflatoxin levels compared to the control. The data obtained indicate that B. subtilis isolates isolated from soil can inhibit aflatoxin in vitro.

The article presents data on a scientific experiment conducted on quails of the Japanese breed. Data on the influence of the prebiotic drug «BioAxel» on the physiological parameters of quails have been established. The dynamics of the live weight of quails when feeding different dosages of the drug is estimated. In the experiment, the positive effect of different doses of the feed additive «BioAxel» on the average daily and gross growth of experimental birds (by 8,2–16,5% compared to the control) was established. The most effective method was feeding part of the BioAxel (5% of the feed weight) plus another part (4%) with water. A comprehensive veterinary and sanitary examination of quail slaughter products was also carried out when using the prebiotic drug «BioAxel»in the diet. It was found that this drug does not have a negative effect on the quality of meat. At the same time, the indicators of biological safety are within the limits of the norm established by current regulatory documents. In terms of nutritional value, the meat of quails raised with the use of the prebiotic drug «BioAxel» exceeds the meat of quails from the control group. The content of essential amino acids significantly increased in poultry meat of the experimental groups, and the total biological value in the test with Tetrahymena pyriformis exceeded the control parameters.
