Co-administration of Layered Double Hydroxide (LDH) Nanosheets on
SW480 Colorectal Cancer Cell Line through Apoptosis Induction
Authors: Soltanzadeh Hossein , Rostami Laaya , Rad Farzad Arjomandi
Published: July 2022

Background:

Colorectal cancer (CC) is common cancer in humans and one of the major
causes of cancer death worldwide. Recently, several therapeutic methods of CC and other malignancies
have been developed, but drug resistance is an important problem in cancer treatment. Therefore,
identifying and providing novel chemotherapeutic agents is important for treating malignancies.

Objective:

In the present study, we investigated the anti-cancer activity of Cuminum cyminum extraction
using layered double hydroxide (LDH) nanosheets on the SW480 CC cell line.

Methods:

The anti-cancer activity of C. cyminum extraction and LDH nanosheets were investigated
on the SW480 CC cell line by MTT assay. The mRNA expression of apoptosis-related genes (BAX
and BCL2) was investigated by the Real-Time PCR method.

Results:

Our results revealed that extraction of C. cyminum significantly decreased proliferation and
viability of SW480 CC cell line in a concentration-time-dependent manner. However, the antiproliferation
effects of C. cyminum extraction by co-administration of LDH nanosheets were significantly
more than its monotherapy. Moreover, the expression of BAX and BCL2 genes in the treated
SW480 cells was significantly upregulated and downregulated, respectively.

Conclusion:

The present study generally revealed significant anti-cancer effects of C. cyminum extraction
and LDH nanosheets combination on SW480 CC cells, which may be due to apoptosis induction.

Published: July 2022

Rapid and suddenly increasing use of small distributed renewable energy resources (DRER) and distributed energy storage (DES), reduced compact dynamic electrical power consumer-like electrical vehicle loads, the requirement of bidirectional power flow communication network to exchange critical information, other ancillary services, etc. has to be envisaged and fulfilled by a future smart distribution grid system. A solid-state transformer (SST) has more potential solutions to provide stable and efficient distribution system operation to overcome the above problem.From various designs of converter control schemes, the solid-state transformer concept has been evaluated and summarised. The benefits and downsides of converters in the AC/DC, DC/DC, and DC/AC stages are studied for the best configuration. The High Frequency Transformer(HFT) is a main part of SST.The design and optimization of a HFT is approached on the objective of minimising the weight and size of the SST.Researchers also face several challanges in the prototype design and implementation of SST before operating effectively in the distribution system which is presented . Some of expected solutions and future recommendations for the establishment of the solid state transformer for future smart electrical distribution systems are discussed.

For description the behavior of materials of the impactor and barrier, the model of a compressible elastic-plastic medium with a variable value of the yield strength. Determined that the classical hydrodynamic theory of the penetration of a cumulative jet into a barrier is not takes into account the effects of the inertial movement of the barrier after triggering separately taken element (aftereffect). The existence of three regimes is distinguished shock interaction - high-speed, when the elements behave like a liquid body, are worked out, but not inhibited; low speed, when the elements behave like solid body and are decelerated as a whole and intermediate, when the elements are decelerated and are deformed at the same time. It is shown that the braking mode of copper elements at high-speed impact on a steel armored barrier is realized at speeds smaller 800…1000 m/s. It is shown that when interacting with an obstacle, high-speed fragmented cumulative jet, the total depth of armor penetration will be greater, than this is predicted by the classical hydrodynamic theory of penetration, and the more more, the higher the speed of the elements and the greater the distance between them on the one hand and less strength of the barrier on the other side.

The results of experimental study of morphology of silver nanostructures, which appear during thermal destruction of polyvinyl alcohol film with silver nitrate are presented. It is shown that during the increase of silver nitrate concentration the maximum size of the formed particles increases from tens of nanometers up to 2 μm, and their shape transforms from spherical to irregular. The growth of silver nanoparticles occurs at the expense of small silver nanoparticles migration on a substrate surface, their gathering near the large nanoparticles and confluence of small nanoparticles with larger ones.

Electron beam annealing was carried out to form amorphous and crystalline germanium clusters in GeO[SiO] and GeO[SiO2] films deposited on quartz and monocrystalline silicon substrates. Using electron microscopy, Raman spectroscopy, and light transmission and reflection spectroscopy, the structural transformations of the films and their optical properties were studied. From the analysis of Raman spectra, it was shown that amorphous germanium nanoclusters are present in the initial GeO[SiO] film, while they are not observed in the initial GeO[SiO2] film. Regimes of electron-beam annealing which are necessary for the formation of germanium nanocrystals in GeO[SiO] and GeO[SiO2] films were found. It was shown that, at the same annealing parameters, the fraction of the crystalline phase of germanium in GeO[SiO] films were smaller than in GeO[SiO2] films. In addition, it was found that the fraction of the crystalline phase at the same annealing parameters is larger for films on a quartz substrate than on monocrystalline silicon substrate. The sizes of germanium nanocrystals formed as a result of electron beam annealing were determined from Raman spectra analysis. The proposed method of obtaining amorphous germanium nanoclusters and nanocrystals in films of nonstoichiometric germanosilicate glasses using electron beam annealing can be used to create ordered arrays of such nanostructures.

We study the electromagnetic radiation of a charged particle bunch with small size moving at a constant velocity and having a variable charge. The environment medium is considered to be isotropic and homogeneous, and it may have frequency dispersion, but not spatial dispersion. The general solution of the problem is obtained. The main attention is paid to the case when the bunch charge, starting from a certain moment, decreases exponentially with time. The saddle point method is used to obtain the approximate expressions for the field components that are valid in the wave zone. The energy characteristics of the excited spherical wave are studied and compared with the case of a decelerating charge. In the case of excitation of Vavilov-Cherenkov radiation, we obtain the asymptotics which are valid in the entire wave zone, including the region in which the field cannot be divided into the spherical and cylindrical waves.

A method is proposed for measuring high-voltage charging potentials of dielectrics under ion irradiation by shifting the boundary of the bremsstrahlung X-ray spectrum. Since there is no bremsstrahlung output during Xe+ ion irradiation, it was proposed to use a probing electron beam to generate bremsstrahlung X-rays. To eliminate the effect of charge compensation on the surface, the value of the current of the probing probe of electrons was selected. The values of the equilibrium charging potentials of Al2O3 ceramics, Al2O3 sapphire, SiO2, and Teflon are obtained at different ion irradiation energies. The data obtained are compared with the results of spectrometric studies.

Authors: Zidoun Youness , Kaladhara Sreelekshmi , Powell Leigh , Nour Radwa , Al Suwaidi Hanan , Zary Nabil
Published: July 2022

Background

Since the beginning of the COVID-19 pandemic, people have been exposed to misinformation, leading to many myths about SARS-CoV-2 and the vaccines against it. As this situation does not seem to end soon, many authorities and health organizations, including the World Health Organization (WHO), are utilizing conversational agents (CAs) in their fight against it. Although the impact and usage of these novel digital strategies are noticeable, the design of the CAs remains key to their success.

Objective

This study describes the use of design-based research (DBR) for contextual CA design to address vaccine hesitancy. In addition, this protocol will examine the impact of DBR on CA design to understand how this iterative process can enhance accuracy and performance.

Methods

A DBR methodology will be used for this study. Each phase of analysis, design, and evaluation of each design cycle inform the next one via its outcomes. An anticipated generic strategy will be formed after completing the first iteration. Using multiple research studies, frameworks and theoretical approaches are tested and evaluated through the different design cycles. User perception of the CA will be analyzed or collected by implementing a usability assessment during every evaluation phase using the System Usability Scale. The PARADISE (PARAdigm for Dialogue System Evaluation) method will be adopted to calculate the performance of this text-based CA.

Results

Two phases of the first design cycle (design and evaluation) were completed at the time of this writing (April 2022). The research team is currently reviewing the natural-language understanding model as part of the conversation-driven development (CDD) process in preparation for the first pilot intervention, which will conclude the CA’s first design cycle. In addition, conversational data will be analyzed quantitatively and qualitatively as part of the reflection and revision process to inform the subsequent design cycles. This project plans for three rounds of design cycles, resulting in various studies spreading outcomes and conclusions. The results of the first study describing the entire first design cycle are expected to be submitted for publication before the end of 2022.

Conclusions

CAs constitute an innovative way of delivering health communication information. However, they are primarily used to contribute to behavioral change or educate people about health issues. Therefore, health chatbots’ impact should be carefully designed to meet outcomes. DBR can help shape a holistic understanding of the process of CA conception. This protocol describes the design of VWise, a contextual CA that aims to address vaccine hesitancy using the DBR methodology. The results of this study will help identify the strengths and flaws of DBR’s application to such innovative projects.

Fish is one of the healthiest food sources once it has proteins, vitamins, minerals and the omega-3 polyunsaturated lipids. Nevertheless, to be healthy, the protein in fish meat must not have contaminants further than allowed. This study aimed to investigate the preclinical toxicologic effects of consumption of fish meat from Cachoeira river (Joinville, Santa Catarina, Brazil). Groups of rats were divided and received for a month: standard ration, farmed fish meat and fish meat from Cachoeira river twice a week. One day after the last exposition, animals were euthanized and blood, spleen, heart, liver, kidney, cerebellum, and cerebral cortex were collected to measure oxidative stress, biochemical and hematological parameters. Metals levels were also analyzed in fish meat by atomic emission spectrometry. Significant elevation of carbonylated proteins were observed in heart and liver and thiobarbituric acid reactive substances in liver, plasma and cerebellum were observed. Total sulfhydryl content decreased significantly in cerebellum, liver and heart, and decreased catalase activity in the liver and superoxide dismutase activity in the kidneys were also present among rats who consumed fish meat from Cachoeira river. No modification of hematological parameters was observed, and only significant decrease of HDL occurred among biochemical parameters. Analysis of metals in river fish meat showed a fivefold increase in zinc and aluminum compared to farmed fish meat. Short-term exposure to fish meat from the Cachoeira River resulted in increased oxidative stress, liable to be transferred through the food chain, possibly associated with the increased presence of heavy metals.
Coloretal Cancer Prevention and Screening before the Economic and Social Impact of Costs for Cancer Treatment In Brazil
Authors: Dornelas Ana Carolina Alves Diniz , Silva Daniel Rodrigues
Published: July 2022

According to the INCA National Cancer Institute, cancer is a term that encompasses more than 100 different types of malignancies that have in common the disordered growth of cells, which can invade adjacent tissues or distant organs. The evolution of cancer is directly correlated with preventive actions, which aim to prevent it from developing, encompassing actions to reduce the risks of having the disease. Cancer prevention encompasses actions taken to reduce the risks of having the disease. By avoiding exposure to risk factors and adopting a healthier lifestyle, early detection and treatment of pre-malignant diseases (e.g. polyps in the intestinal walls) or early asymptomatic cancers that often enables successful treatment, even leading to cure. The present work makes a reflective study on the challenges of implementing public policies for the prevention of colorectal cancer and its economic and social impact. We take as a theoretical basis the considerations of CANCELA (2019), LIMA (2015) and SCANDIUZZI et all (2019) in addition to the data provided by INCA and the Ministry of Health. The bibliographic analysis reveals that public policies for the prevention of colorectal cancer are still very scarce in view of the magnitude in which the disease has been growing. Screening and early detection is an action aimed at the population in the subclinical phase with the objective of reducing the incidence of invasive cancer and the mortality rate, still so little explored by public managers.It is concluded that access to treatment for colon and rectal cancer is unequal in Brazil, and depends on the resources available in each region of the country and that socioeconomic and clinical factors are associated with the waiting time for the start of treatment, thus reflecting, barriers to timely access to treatment. There is an urgent need to create screening protocols and conditions for the implementation of public policies that value the work of colorectal cancer prevention. There are also strategies that require greater encouragement even from the Ministry of Health itself, such as health education actions to raise awareness of the population, training of health professionals and articulation of the system with the service network, seeking to carry out diagnostic tests. and facilitating access to treatment.

Broj stanovnika Srbije opada već tri decenije, a demografske projekcije pokazuju da će stanovništvo Srbije opadati i u budućnosti, čak i ako se stopa ukupnog fertiliteta podigne do nivoa reprodukcije. U osnovi depopulacije stoje tri grupe determinantni: niske stope fertiliteta i smanjen broj žena u fertilnom periodu, spoljašnje i unutrašnje migracije i visoke stope smrtnosti. Svaka od njih ima svoje specifičnosti koje se tiču kako geografskih, tako i strukturnih odlika pojedinaca i porodica. Državni odgovor na depopulaciju bio je usmeren na pitanje broja: beba i migranata. Nizom strategija i mera, država pokušava da podigne stope fertiliteta i smanji migracije. Vodeći domaći i međunarodni demografi slažu se da je mala verovatnoća da će pronatalitetne mere dati rezultat, te zato predlažu da se depopulaciji priđe ne sa fokusom na veličinu stanovništva, već na kvalitet, odnosno, stepen razvijenosti ljudskih resursa. U ovom pristupu, ključni mehanizam jačanja ljudskih resursa jednog društva jeste podizanje stepena obrazovanja stanovnika, a samim tim i njihove produktivnosti, socijalne i političke inkluzije. U ovom tekstu iznosimo konture jednog takvog pristupa koji je deo najnovijeg Izveštaja o ljudskom razvoju za Srbiju (Human Development Report) koji pripremaju UNDP i UNFPA. Analizirajući pokazatelje regionalnog razvoja, tržišta rada i obrazovanja, pokazujem kako mogu izgledati te nove populacione politike za nove demografske okolnosti. Imajući u vidu da će se stanovništvo Srbije smanjivati, a da značajni njegovi delovi nisu potpuno integrisani, pokazujem kako će različite sektorske politike (obrazovanja, tržišta rada i regionalnog razvoja) morati postati osetljive na demografska razmatranja i kako će onda one biti razvojne inkluzivne politike koje će rešiti neke demografske probleme u budućnosti.

Published: July 2022

Zdravstvena kriza izazvana globalnim širenjem virusa Kovid-19, ima brojne negativne implikacije na sve društvene sfere i stavlja brojne države, sisteme, ali i pojedince, pred višestruke izazove. Restriktivne mere koje su vlade zemalja donosile od početka pandemije sa ciljem sprečavanja (nekontrolisanog) širenja virusa imaju negativne efekte ne samo na globalnu ekonomiju i pojedince koji su u povećanom riziku, već i mentalno zdravlje celokupne populacije. Nesigurnost zaposlenja, gubitak posla, konstanto prisustvo osećanja straha za sopstveno, ali i zdravlje bliskih ljudih, depresija i usamljenost su samo neki od faktora rizika koji su u pozitivnoj korelaciji sa stopom samoubistva. Stoga je opšti predmet ovog rada analiza uticaja pandemije tokom prve godine na stope samoubistva u Srbiji kroz prizmu faktora rizika za mentalno zdravlje koji su se javili, odnosno naročito intenzivirani kao posledica primena mera koje su imale kao cilj zaštitu zdravlja stanovništva i rastrećenje zdravstvenog sistema. Cilj rada se ogleda u komparaciji broja samoubistva u godinama koje su prethodile pandemiji i tokom 2020. godine, kada su i preduzete mere, kao što su zabrana i/ili ograničenje kretanja i kontakata i socijalna izolacija, bile najrestriktivnije sa stanovišta ljudskih prava i sloboda. U radu je data analiza na koji način i u kom intezitetu su potencijalno ove mere uticale na mentalno zdravlje populacije, kao i kakve su projekcije uticaja ovih faktora rizika na suicid u Srbiji u predstojećem periodu.

Published: July 2022

Urinary tract infection (UTI) in the community is a common infection in humans. The causative microorganisms for UTIs may vary in different places and also vary in their antibiotic sensitivity and resistant patterns. This study aimed to find out the incidence of gram-negative bacteria along with their antibiotic sensitivity pattern in community-acquired UTIs and to calculate the existence of Extended-spectrum beta-lactamase (ESBL) positivity among them. A Sum of 515 urine samples was tested and the causative organisms were identified. Antibiotic susceptibility tests were executed where it had shown growth for bacteria by both manual and automated methods. ESBL tests were performed to identify ESBL-producing isolates. From a total of 515 samples, 65 (12.65%) were culture positive for UTIs. The rate of infection was higher in females than in males. The most prevailing bacteria were Escherichia coli and Klebsiella pneumoniae. Out of total culture-positive isolates, only 43.08% were ESBL positives. The study found that the organisms displayed resistance to Ciprofloxacin and Cefixime and sensitivity to Gentamicin, Ertapenem, and Nitrofurantoin. Females have a higher prevalence of UTIs than males. Mostly, females suffer from UTIs in their reproductive years whereas males suffer in their old age. The prevalence of gram-negative bacteria is higher in community-acquired UTIs. These pathogens though present in the community, becoming resistant to commonly used antibiotics like Ciprofloxacin and Cefixime because of overuse and misuse of antibiotics at the community level.

Mapping Racial Geographies of Violence on the Colonial Landscape
Authors: Waldron Ingrid
Published: July 2022

This paper unpacks the concept of “spatial violence” to examine the social justice dimensions of race, place, space, and the Indigenous and Black communities in Canada. The paper highlights the larger socio-spatial processes that create disproportionate exposure and vulnerability to the harmful social, economic, and health impacts of inequality in Indigenous and Black communities. It also argues that the lived experience of spatial violence and toxic exposure live together and that it is not possible to understand their impacts in Indigenous and Black communities in isolation. The paper also disrupts traditional notions of “the environment” that are centered on harmonizing cities and nature by highlighting the symbolic and materiality of space, especially with respect to how it harms Indigenous, Black and other racialized communities.
Constant gap between conventional strategies and those based on C*-dynamics for self-embezzlement
Authors: Cleve Richard , Collins Benoit , Liu Li , Paulsen Vern
Published: July 2022

We consider a bipartite transformation that we call self-embezzlement and use it to prove a constant gap between the capabilities of two models of quantum information: the conventional model, where bipartite systems are represented by tensor products of Hilbert spaces; and a natural model of quantum information processing for abstract states on C*-algebras, where joint systems are represented by tensor products of C*-algebras. We call this the C*-circuit model and show that it is a special case of the commuting-operator model (in that it can be translated into such a model). For the conventional model, we show that there exists a constant ϵ0>0 such that self-embezzlement cannot be achieved with precision parameter less than ϵ0 (i.e., the fidelity cannot be greater than 1−ϵ0); whereas, in the C*-circuit model---as well as in a commuting-operator model---the precision can be 0 (i.e., fidelity 1).Self-embezzlement is not a non-local game, hence our results do not impact the celebrated Connes Embedding conjecture. Instead, the significance of these results is to exhibit a reasonably natural quantum information processing problem for which there is a constant gap between the capabilities of the conventional Hilbert space model and the commuting-operator or C*-circuit model.

There are five Platonic solids in three dimensions, but there are also solids with Platonic properties (also known as regular polyhedra) in four and higher dimensions. The concept of Platonic Bell inequalities in the three-dimensional Euclidean space was introduced by Tavakoli and Gisin [Quantum 4, 293 (2020)]. For any three-dimensional Platonic solid, an arrangement of projective measurements is associated where the measurement directions point toward the vertices of the solids. For the higher dimensional regular polyhedra, we use the correspondence of the vertices to the measurements in the abstract Tsirelson space. We give a remarkably simple formula for the quantum violation of all the Platonic Bell inequalities, which we prove to attain the maximum possible quantum violation of the Bell inequalities, i.e. the Tsirelson bound. To construct Bell inequalities with a large number of settings, it is crucial to compute the local bound efficiently. In general, the computation time required to compute the local bound grows exponentially with the number of measurement settings. We find a method to compute the local bound exactly for any bipartite two-outcome Bell inequality, where the dependence becomes polynomial whose degree is the rank of the Bell matrix. To show that this algorithm can be used in practice, we compute the local bound of a 300-setting Platonic Bell inequality based on the halved dodecaplex. In addition, we use a diagonal modification of the original Platonic Bell matrix to increase the ratio of quantum to local bound. In this way, we obtain a four-dimensional 60-setting Platonic Bell inequality based on the halved tetraplex for which the quantum violation exceeds the 2 ratio.

Inflammation is the vital part of the immune system's response to injury and infection. It is the body's way of signaling the immune system to heal and repair damaged tissue. The objective of this paper is to design and synthesize a new isoindoline 1,3-dinoe  derivative  and  investigate  their  selective  anti  inflammatory  activity  to  COXs.  As  a  potential  anti-inflammatory compound, Isoindoline-1,3-dione derivatives were synthesized from the addition reaction of phthalimide, formaldehyde, catalytic amount of potassium hydroxide and cyclic amine in ethanol yielded the desired Isoindoline-1,3-dione compounds (ZJ1-ZJ6. 1H- NMR, ¹³C-NMR, FT-IR   and elemental analysis were consistent with the assigned structures. Isoindoline-1,3-dione derivatives exhibited good inhibitory activity against the COX enzymes. To explain the result of our investigation to COX-1 and COX-2 and the selectivity of our compounds to either COX-1 or COX-2, the rationalization in COX-1, the amino group participate more effectively in binding with the ligand while in COX-2, the aryl group is more effective in binding to the ligand. The amino acetylenic compounds behave differently toward COXs from our compound. ZJ4 have shown some selective COX-1 ligand efficiency while ZJ1 promised a potent blockage and ligand efficiency toward the COX-2 enzyme which was found to be higher than the marketed drug Indomethacin and near potency score of Celecoxib. For the first time, this indicates the requirement of investigating the removal of acetylenic group in this study showed that it might be a different binding site in COXs which may result in effective compounds.

The article deals with assessment of the Earth`s gravity field variations (GFV) affecting the repeated leveling results using modern geospatial analysis tools in the study of natural and engineering objects’ deformations. The basis of the calculation is put in the well-known formula that connects reference level of the point displacement with potential of gravity variation on it, caused by the volume of the redistributed surrounding masses. The desired change in the potential is determined by the method of numerical integration through the sum of elementary masses redistributed volume’s contributions to it. At estimating we used the possibility of obtaining the most reliable digital model of various landforms in the ArcGIS software environment and determining the dimensions of a complex body with a fairly high accuracy. In this case, the advantage of the rectangular partition into elementary volumes of the quasi-cone layer base, which is close in geometry to the shapes of igneous or man-made rocks model over the radial one is shown. The developed method for calculating the impact of GFV on leveling using the capabilities of ArcGIS is fully automated through compiling the corresponding script in python. Specific experimental material shows that it is possible to assess the above mentioned impact with any detailing

Published: July 2022

The authors describe the process of office mine-survey geodetic and cartographic works at the fields of PLC Gazprom Dobycha Yamburg using one of the world`s most widespread geographic information systems (GIS) MapInfo. However, it does not have a sufficient number of ready-made tools designed to solve narrowly focused, practical tasks in underground surveying. In particular, at performing works on arranging plane-and-height measurement of pipelines at the Yamburg oil and gas condensate field, they faced the problem of lacking the necessary tools for creating their lengthwise profiles. Using the capabilities of the program, to automate the construction of the mentioned profiles and increase the economic efficiency of the production process in the MapInfo GIS in the MapBasic programming language, a software module "Construction of various purposes pipelines’ lengthwise profiles" was created. The module is designed to automate the processes of constructing such profiles, piping of gas well clusters, gas pipelines-collectors, on-site networks for different goals, associated with the multiple repetitions of many operations previously performed manually. The construction of a lengthwise profile in this software product enables eliminating errors at transferring marks obtained as a result of field changes. The use of the software module can significantly reduce the time at preparation of reporting as- built documentation.

The article deals with the identification of the memorials of domestic cartography. The study of cartographic heritage is one of the main tasks in the Russian history of this science. The selection of works for classification as artifacts of our cartography is based on scientific analysis and examining the materials. A clear definition of a map-making memorial does not exist today; in this regard much attention is paid to the methods of studying such works. The criteria and methods for determining the significance of various publications, as well as their application to cartography, are considered, the procedure for entering a map or atlas into the Register of Book Monuments of the Russian Federation is investigated. On the example of the Map of Russian possessions in Transcaucasia, the way is shown from the discovery of the source, its examination, the identification of historical value, to classifying a cartographic work as a book and cartographic artifact.
