NURBS upper bound prey-predator scheme for collapse analysis of masonry vaults
Authors: Grillanda Nicola , Chiozzi Andrea , Milani Gabriele , Tralli Antonio
Published: March 2021

We present here an improvement in the non-uniform rational Bezier spline (NURBS)-based kinematic limit analysis approach, which has proven to be particularly effective for masonry vaults, by adding an innovative mesh adaptation scheme. The procedure is based on the application of the kinematic theorem of limit analysis on a 3D model composed of NURBS rigid blocks. The definition of curved geometries through NURBS surfaces allows using mesh of few elements without modifications of the real geometry. An adjustment of the initial mesh is needed to minimize the kinematic load multiplier. Therefore, a Prey-Predator Algorithm (PPA), an innovative meta-heuristic algorithm based on the natural interaction between a predator and preys, is implemented as core of the mesh adaptation, allowing an efficient evaluation of load-bearing capacity and collapse behavior of masonry vaults. In this work, the standard PPA is further improved by introducing a variable population size, the so-called saw-tooth model, which allows reducing the computational effort without penalizing the evaluation of the objective function. Some numerical examples, which involve a masonry arch, a skew arch, and a horizontally loaded dome, are finally analyzed. For all the cases, a comparison between the proposed PPA and a traditional Genetic Algorithm (GA) is presented.
Slope stabilisation of railway embankments over loose subgrades using deep-mixed columns
Authors: Astaraki Farshad , Esmaeili Morteza
Published: March 2021

An investigation was undertaken into the stability of railway embankment slopes over soft subgrades stabilised by deep-mixed columns (DMCs). Three 1 : 10 scale laboratory embankments were constructed over unreinforced and reinforced subgrade with DMCs in square and triangle patterns. The load–settlement responses of both embankments and columns were measured. The laboratory embankments were then mathematically modelled and the results were compared. After validation, a comprehensive parametric study was carried out to evaluate the factor of safety (FoS) of the embankment side slopes against sliding. Five embankment soil types from poor to high strength, three heights from 1.5 to 10 m and various DMC improvement area ratios from 0 to 65% were considered. The experimental outcomes indicated an increase of nearly 63% in the bearing capacity of both DMC-supported embankments compared with the unreinforced one. Regarding the parametric study, a minimum required FoS of 1.5 was observed for 1.5 m embankments of all soil types stabilised with a 60% improvement ratio. The greatest safety increase was associated with a 1.5 m height embankment with poor soil type, which showed a 36% increase.
Bio-stabilisation of soft soil using cattle manure
Authors: Rao Sudhakar M. , Sukumar Reshma , Joshua Rita Evelyne , Rekapalli Monica
Published: March 2021

Environmentally friendly materials are being explored as alternatives to lime and cement binders in ground improvement. Biological treatment methods are environmentally friendly as they rely on the natural activity of ubiquitous microbes to produce extracellular polymeric saccharides (EPS) and calcite cements. EPS extruded by microbes exhibit strong adhesion from growth of fibrous bridges and bonds between surfaces. In situ polysaccharide secretion in soils to improve their engineering properties has not been examined. In this study, pulverised dried cattle manure (CM) are is used for in situ EPS production in a synthetic soft soil specimen. The indigenous facultative anaerobes and aerobes in animal waste produce negatively charged EPS molecules in the soil specimen. Bridging of sand particles and embedment of CM fibres in kaolinite aggregates caused an immediate increase in unconfined compressive strength (UCS) of the stabilised specimen. EPS cementation improved soil strength by filling pores and engulfing kaolinite aggregates into bonded mass. Fibre reinforcement and bio-stabilisation by CM increased the UCS of the soil by 740%. Replacing C-intensive lime/cement binders by CM as a stabilising agent has the potential to prevent release of 1 t of carbon dioxide to the atmosphere per tonne of lime/cement consumed.

Published: March 2021

The urban geological environment should be the main carrier for the socio-economic system, a comprehensive geological survey and economic evaluation provide the basis for sustainable development of underground space resources. According to the experience of new town planning in China, there is a need for scientific exploration and planning for underground space in order to overcome the limitations of available urban surface space. Through in-depth analysis of geological background in the Beijing area, some typical geological engineering and geo-environmental problems are put forward in this study, such as changing of groundwater level, deterioration of groundwater quality, land subsidence, active faults, hazardous gas and covered karst collapse. In addition, it is necessary to incorporate three-dimensional urban planning into conventional planning practices with a dynamic decision-making process. For Beijing, economic evaluation, including the environmental security, land-use regulations, public finance and risk management of underground space is also forecasted in this study.

Authors: BAŞER Sümeyye , ISMAYIL Aynur , MAÇİN Salih
Published: March 2021

Aim: Diagnosis of echinococcosis is based on clinical symptoms, imaging techniques and particularly on the detection of specific antibodies in serum specimens of patients. The aim of this study is retrospective evaluation of seropositivity from patients who is diagnosed as Cystic echinococcosis.
Materials and Methods: In this study, the blood serum samples of patients, which were sent to the Medical Microbiology Laboratory from several clinics of the Selcuk University Medical Faculty Hospital between 01 January 2015- 01 July 2020, were evaluated in terms of Cystic echinococcosis by using indirect hemaglutination test. The results were evaluated with a cut off titer ≥160 of as recommended by the manufacturer. Results were evaluated by gender and ages.
Results: Cystic echinococcosis (CE) was determined to be seropositive 332 (21.6%) of 1543 patient samples. Seropositivity was found in 226 (14,7%) of 933 female patients and in 106 (6,9%) of 610 male patients. Seropositivity was mostly seen in 21-40 age group.
Conclusion: While there have been a number of animal studies, little information is available about the prevalence of Cystic echinococcosis in humans in Turkey. Cystic echinococcosis continues to be a majör public health problem in the Konya province. Large scale prevention and control programs should be implemented against this disease.

Authors: DOĞAN Mehmet
Published: March 2021

Aim: COVID-19 pandemic has become one of the most critical health problems of the 21st century. Healthcare workers undoubtedly fulfil the most crucial task of combating this critical health problem all over the world. This study was carried out to determine the experiences of pre-hospital emergency healthcare workers during the COVID-19 process.
Material and Method: This descriptive and cross-sectional study was conducted on 204 healthcare workers working in Kayseri province, Turkey's pre-hospital emergency health services.
Results: 50.5% of the participants were women, 69.1% were married, and the average age was 31.7 ± 5.8. 45.6% of them were working as an Emergency Medical Technician, and 85.8% were university graduates. 99.0% of the participants state that the workload had increased during the COVID-19 process. 42.2% of the participants had a coronavirus test and 27.9% of those who had the test had a positive test result. During the COVID-19 process, 14.7% of participants were separated from their families, which adversely affected 90.0% psychologically. While it appears that the participants used personal protective equipment during the COVID-19 process, this increase was 98.5% in wearing a mask. 70.6% of the participants stated an increase in violence against healthcare workers during the COVID-19 process, and 63.7% of them indicated that they experienced violence during this period.
Conclusions: During the COVID-19 process, the workload of pre-hospital emergency healthcare workers increased. As a society, support should be given to the combat against the pandemic by following precautions and to healthcare workers due to their devoted work.
Beyond Ego and Alter: Enlarged Democratic Deliberation
Authors: Piromalli Eleonora
Published: March 2021

According to a frequent objection coming from the tradition of political realism, deliberative democracy is impotent in the face of actors who, wielding power and money, refuse to engage in deliberation, or seek to distort deliberative processes. With the aim of disproving this objection, in this essay I proceed in three steps: first of all, I show that the realpolitik objection is based on a dyadic, two-person theoretical model of argumentative speech acts. To this model, considered limited and unsatisfactory by many sociolinguists, I counter a more complex and articulated framework. Second, I aim to demonstrate that this latter framework is capable of accounting for a temporally and spatially enlarged democratic deliberation which can be rejected or distorted barely, if at all, by agents relying on positions of power. In the third section, I highlight the many and important differences in grounding, nature and finalities between the model of enlarged democratic deliberation and forms of power politics based on strategic calculations and tactical alliances. Finally, I focus on the application of the model to societies characterized by structural injustices and distortions, with the aim of showing how it can help marginalized and victimized groups have their requests heard and discussed in the public sphere and in deliberative settings.
Contesting Forms of Knowledge in Policy Deliberation Lessons from Disaster Coping Policies in Thailand
Authors: Boossabong Piyapong , Chamchong Pobsook
Published: March 2021

This article presents the case of policy deliberation on disaster coping strategies in Bangkok, Thailand. It demonstrates the challenges scientists faced when they sought to influence policymaking on flood mitigation. The article demonstrates different forms of knowledge that shaped Bangkok’s flood policy, and explains how lay knowledge promoted by farmers, local communities, and Buddhist monks were successful in persuading policymakers and the wider public in their preferred policy option. Meanwhile, scientific knowledge failed to make their case in public forums, and on some occasions, even alienated Thai citizens. The article concludes by drawing lessons on how scientific and lay knowledge can better contest as well as connect their claims to enrich the process and outcomes of public deliberation on disaster coping policy.
Clinical supervision in South Africa: Perceptions of supervision training, practices, and professional competencies
Authors: Hendricks Shariefa , Cartwright Duncan J. , Cowden Richard G.
Published: March 2021

We investigated South African clinical and counselling psychology supervisors’ (n=44) perceptions of supervision training, their supervision experiences, and their perceived competence, confidence and effectiveness in providing supervision. Results indicated that many supervisors prematurely engage in supervision responsibilities and initiate supervision prior to receiving formal training in supervision. With limited regulatory guidelines available on supervision training and practices in South Africa, the findings indicate a need for the South African psychology profession to establish a formal regulatory framework on supervision training and practices. This includes identifying supervision training needs, developing training programmes, and instituting formal training requirements for practitioners who participate in clinical supervision.Significance:

The sample of South African clinical and counselling psychologists involved in the supervision of trainee psychologists tended to engage in clinical supervision in advance of obtaining three years of independent clinical practice and prior to receiving appropriate training in providing supervision.
There is a need for the Professional Board for Psychology of the Health Professions Council of South Africa (PBP-HPCSA) to appropriately monitor and enforce ethical obligations of psychologists who engage in supervision of trainee psychologists.
Psychologists who provide clinical supervision to trainee psychologists ought to take personal responsibility for ensuring that they are appropriately trained and have acquired the necessary competencies to provide supervision before deciding to engage in supervision activities.
Formal guidelines and policies regulating clinical supervision are necessary for ensuring psychology supervisors obtain appropriate training in supervision and fulfil mandatory HPCSA accredited supervision training requirements.

Published: March 2021

Several dozen stones of an ordinary chondrite meteorite fell in and around the town of Benenitra in southwestern Madagascar during the early evening of 27 July 2018, minutes after a widely observed meteor fireball (bolide) transit and detonation. The event was confirmed by low-frequency infrasound recordings received at ~17h15 UTC (Coordinated Universal Time; 19h15 local time) at the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO) infrasound station I33MG near Antananarivo, 542 km north-northeast of Benenitra. An energy release equivalent to 2.038 kt of TNT was calculated from the infrasound signals. Seismograph readings at the SKRH station 77 km north-northwest of Benenitra recorded a twostage signal consistent with the arrivals of an initial air-coupled ground wave at 16h48:08 UTC and a stronger pulse at 16h49:22 UTC linked directly to the atmospheric pressure wave. The infrasound and seismic signal arrival times suggest that the bolide entry and detonation occurred at approximately 18h46 local time (16h46 UTC), entry was from the northwest, and the detonation hypocentre was located within ~20 km of Benenitra. Despite meteorite debris being found among buildings within Benenitra, there was no damage to structures or injuries reported. Eyewitness accounts and photographic records indicate that approximately 75 mostly intact stones were collected; however, the remoteness of the area, the rugged nature of the terrain and sales of fragments to meteorite collectors have limited scientific analysis of the fall and the extent of the strewn field. The total mass of recovered stones is estimated at between 20 kg and 30 kg, with one fragment of 11.2 kg and several of ~1 kg. Petrographic and mineral chemical analyses indicate that the stones belong to the L6 class of ordinary chondrites. Cosmogenic radionuclide analysis confirms that the fall is linked to the bolide event. The name Benenitra has been officially accepted by the Meteoritical Bulletin Database.Significance:

Eyewitness reports, CTBTO infrasound records, seismograph records and cosmogenic radionuclide analysis confirm a meteorite fall over Benenitra on 27 July 2018.

Petrographic and geochemical analyses confirm that the meteorite is an L6 ordinary chondrite.

Recovery of meteorite falls is rare; this is Madagascar’s second known meteorite fall and the first that can be linked to a bolide.

Regional and global science monitoring networks can be interrogated to improve the understanding of bolide events.

Interaction of scientists with local communities is important to dispel misunderstandings around scientific phenomena, and can improve collection of data.
Dental caries in South African fossil hominins
Authors: Towle Ian , Irish Joel D. , De Groote Isabelle , Fernée Christianne , Loch Carolina
Published: March 2021

Once considered rare in fossil hominins, caries has recently been reported in several hominin species, requiring a new assessment of this condition during human evolution. Caries prevalence and location on the teeth of South African fossil hominins were observed and compared with published data from other hominin samples. Teeth were viewed macroscopically, with lesion position and severity noted and described. For all South African fossil hominin specimens studied to date, a total of 10 carious teeth (14 lesions), including 4 described for the first time here, have been observed. These carious teeth were found in a minimum of seven individuals, including five Paranthropus robustus, one early Homo, and one Homo naledi. All 14 lesions affected posterior teeth. The results suggest cariogenic biofilms and foods may have been present in the oral environment of a wide variety of hominins. Caries prevalence in studied fossil hominins is similar to those in pre-agricultural human groups, in which 1–5% of teeth are typically affected.Significance:

This study adds to the growing evidence that dental caries was present throughout the course of human evolution. Caries prevalence in the fossil species studied is similar to those in non-agricultural human groups, with 1–5% of teeth displaying cavities.
Differences in prevalence and position of dental caries can provide insight into dietary aspects of past populations. South African fossil hominins display lesions on their posterior teeth, suggesting sugary foods were consumed.
New AMS dates for the Middle Iron Age in the Mapungubwe landscape
Authors: Huffman Thomas N. , Woodborne Stephan
Published: March 2021

Research in the Limpopo Valley has documented over 500 Middle Iron Age sites (AD 900–1320) relevant to the origins of Mapungubwe – the capital of the first indigenous state in southern Africa. Fifteen new accelerator mass spectrometry (AMS) dates from 11 of these archaeological sites establish the boundaries of the ceramic facies that form the culture-history framework for such diverse topics as land use, ethnic stratification, population dynamics and rainfall fluctuations. Mapungubwe was abandoned at about AD 1320.Significance:

Because Mapungubwe developed relatively recently (circa AD 1200), it can clarify the origins of older states.
Environmental factors such as droughts, along with agriculture and trade, played a role in the abandonment of Mapungubwe.

Published: March 2021

Two types of hydrodynamically lubricated plain journal bearings were subject to examination differing in the method used to feed them with oil. The first type was fed from a lubrication pocket and the second from the bearing face side. Mathematical models were developed
with two-way oil flow allowing to determine the oil film bearing capacity, the maximum
pressure, the maximum temperature, and the film oil minimum height for given position of
journal relative to solid bush. Static characteristics were developed used in the further course
of the study to compare operating parameters of the considered types of bearings. Another
issue considered in the paper is the effect of oil VG grade on bearing performance with conditions of oil feeding taken into account and results of the research presented.
Disentangling Mining and Migratory Routes in West Africa: Decisions to Move in Migranticised Settings
Authors: Bolay Matthieu
Published: March 2021

This article scrutinizes the trajectories of African men whose cross-border movements intersect two types of mobility routes: mining and migration routes. Drawing on field research in Mali and Guinea, as well as phone interviews with male miners/migrants in North Africa and Europe, this article provides a case to empirically question some of the premises in the approach to migration decision-making by giving a voice to African men moving across borders who do not necessarily identify as (prospective) ‘migrants.’ Building upon International Organization for Migration data and secondary sources, this article starts by sketching where migration and mining routes overlap. It then examines, in detail, the mobility trajectories of men who were sometimes considered migrants and other times miners in order to identify how these different routes relate to one another. While overseas migration is certainly not a common project for itinerant miners, the gold mines constitute a transnational space that fosters the expansion of movements across the continent, including outside the field of mining. Rather than encouraging overseas migration, gold mines appear to be more of a safety net, not only for seasonal farmers or young people in search of money and adventure, but also, increasingly, for people who are confronted with Europe’s intra-African deportation regime.
Hope, Disillusion and Coincidence in Migratory Decisions by Senegalese Migrants in Brazil
Authors: Jung Philipp Roman
Published: March 2021

Uncertainty is an essential characteristic of our lives. However, by moving from one country to another, from a familiar context to an unfamiliar one, uncertainty becomes a key element of migrants’ decisions. In times of restricted mobility regimes, migrants often do not know if they will be able to reach the desired destination. Even if they manage to do so, it is still uncertain if they will be able to fulfil their aspirations. However, uncertainty also leaves room for hope. Departing from the conceptualisation of hope as the simultaneity of both potentiality and uncertainty and from the concept of circumstantial migration, this article analyses (1) retrospectively the decision of Senegalese migrants to move to Brazil and (2) the intentions of onward migration. Based on empirical data collected through ethnographic fieldwork in four Brazilian cities, this article shows how migration as a form of social hope is redirected to new destinations and that this redirection is a consequence of circumstances and coincidences, which enable or prevent movement. Potential positive outcomes of migration outweighed negative ones, which play a minor role and hardly affect decisions to leave Senegal. However, decisions to emigrate are often based on incomplete information and ill-informed expectations regarding the circumstances at the destination and can lead to feelings of disillusion. The impact of uncertainties shows a more differentiated picture in the context of onward migration intentions. While some migrants are willing to take big risks in onward migration, others try to minimize uncertainties.

Dessa forma, o objetivo do presente trabalho é relatar uma ação extensionista realizada por meio de uma oficina em um ambiente não-formal de educação. A oficina focava na divulgação dos riscos ligados a Multitarefa com Mídia, direção e consumo de álcool. Para isso, duas ações foram combinadas: a primeira abordou o tema Multitarefa com Mídia e a segunda associou a prática de Multitarefa com Mídia, direção e consumo de álcool. Ambas oficinas associaram conteúdos teóricos com atividades práticas. Como resultado, participaram destas ações alunos da Educação Básica, Educação Básica na modalidade Educação Especial e comunidade em geral. Os visitantes vivenciaram simulações, experimentos e puderam refletir sobre os prejuízos em potencial da combinação multitarefa, álcool e direção. O feedback dos visitantes foi positivo.

AbstractMedia Multitasking is a phenomenon in which more than one task is performed simultaneously, being one of the activities with electronic devices. This practice negatively impacts several everyday situations. It can often be associated with driving and even involve drinking alcohol, potentially making it a fatal combination. Thus, the potential risks associated with these practices must be disclosed, and university extension can contribute by promoting Scientific Dissemination actions. Thus, this paper aims to report an extension action through a workshop in a non-formal educational environment. The workshop focused on disclosing the risks related to Multitasking with Media, management, and alcohol consumption. For this, two actions were combined: the first approached the topic of Multitasking with Media, and the second associated the practice of Multitasking with Media, driving, and alcohol consumption. Both workshops associated theoretical content with practical activities. As a result, students from Basic Education, Basic Education in the Special Education modality, and the community, in general, participated in these actions. Visitors experienced simulations, experiments, and reflected on the potential losses from the combination of multitasking, alcohol, and driving. The feedback from visitors was positive.

Published: March 2021

AbstractChronic ankle instability (ICT) is common in jumping sports, may alter muscle recruitment, result in functional limitations and recurrence of sprains in this joint. The purpose of the study was to compare the muscle recruitment of the anterior tibial and long fibular muscles of athletes with and without chronic ankle instability by means of surface electromyography. Thirty-four athletes were recruited, divided into instability group (GI: n=14) and control group (GC: n=20), of both sexes and from different sport modalities, aged between 18 and 27 years old, history of ankle sprain in the last 12 months and functional limitation established by the Cumberland Ankle Instability (CAIT) questionnaire, the recruitment of the anterior tibial and long fibular muscles was analyzed by surface electromyography during the lunge exercise. The results for GI and GC were, respectively: age 21.3±2.88 and 22.4±3.25, height 1.77±0.10 and 1.74±0.08, CAIT 17[12.2-19] and 29.5 [27-30] (p<0.001). The anterior tibial and long fibular muscle recruitment in GI was 111.1[62.5-165.4] and 68.2±29, respectively and in GC 106.8[79.8-230.5] and 54.4±26.4, without significant difference. ICT did not interfere in the recruitment of the anterior tibial and long fibular muscles during the lunge exercise in athletes.

Immunizing Mice using Recombinant Truncated p72 Protein of African Swine Fever Virus and Establishment of an Indirect ELISA
Authors: Wang Jinliang
Published: March 2021

African swine fever (ASF) is a serious infectious pestilence characterized by bleeding in domestic pigs. Therefore, it is necessary to develop effective methods to diagnose this virus, serological detection of specific antibodies against ASFV infection is important for successful clinical diagnosis. In this study, E. coli was used to express the truncated P72 (tP72) gene cloned into the prokaryotic expression vector pET28a (+). Rosetta (DE3). An indirect ELISA assay which against African swine fever virus (ASFV) was established by using purification of recombinant tP72 protein as coated material for detection antibodies. Most effective in exhibiting positive result was observed when the coated material at a concentration of 3.625 μg/mL, serum was diluted to 1:160 and the concentration of HRP-conjugated secondary antibody was 1:2000. Our results showed that the method displayed an excellent specificity (100%) and better sensitivity (1:1600) during serological test based on the criterion of an average value plus three standard deviations. © 2021 Friends Science Publishers

Authors: M. Kaabi Aaishah
Published: March 2021

This study was conducted to investigate the effects of raw honey obtained from black seed or Sider and honeybee pollen as an additive in sheep oocyte maturation medium on the oocyte maturation rate, changes in oocyte glutathione (GSH) levels and expression of developmental candidate genes (GDF-9, MPF, C-MOS, IGF-1, BAX). Healthy immature oocytes of Najdi sheep were cultured in a medium supplemented with 5.0% Sider or Nigella sativa (black seed) honey + 1.0 μg/mL honeybee pollen, and after 24 h of incubation, the effects on the improvement of in vitro oocyte maturation were evaluated. Results demonstrated that the mean oocyte maturation rate was the best in group treated with 5% N. sativa (Group 3) compared with group treated with Sider or N. sativa honey (Group 1A and B, respectively). Mean GSH level was higher in Group 3 oocytes (11.09 ± 0.29 nmol) than in Group 2 oocytes (honey alone; 10.93 ± 0.57; P ≤ 0.05). Mean GSH levels were significantly decreased in Group 1. Expression analysis of candidate genes showed significant upregulation of GDF-9, cyclin B, C-MOS and IGF 1 genes in Group 3 and downregulation of BAX compared with control Group 1. In conclusion, addition of 1.0 μg/mL honeybee pollen along with one of two types of bee honey (Sider and N. sativa) at 5% concentration to the in vitro maturation medium of Najdi sheep oocytes has a beneficial effect in improving the maturation rate and gene expression and increasing the glutathione concentration in matured oocytes. © 2020 Friends Science Publishers
Cold Plasma Treatment on Mustard Green Seeds and its Effect on Growth, Isothiocyanates, Antioxidant Activity and Anticancer Activity of Microgreens
Authors: Saengha Worachot
Published: March 2021

The aims of this work were to study growth, isothiocyanate (ITC), bioactive content, antioxidant activity and anticancer activity of mustard green (MG) microgreens grown from seeds treated with cold plasma at 21 and 23 kV for 5 min. Microgreens from plasma-treated seeds at 23 kV showed almost 2-fold increased ITC content (1.57 ± 0.05 mmol/100 g DW) compared to MG from seeds without plasma (control), showed the highest total phenolic content (TPC) (6.76 ± 0.14 mg GAE/g DW) and total flavonoid content (TFC) (0.16±0.01 mg RE/g DW). However, MG plasma-treated seeds at 21 kV showed the highest antioxidant activity from 2,2-Diphenyl-1-picrylhydrazyl (DPPH) assay (3.51 ± 0.38 mg TE/g DW). Allyl isothiocyanate and 3-butenyl isothiocyanate were the dominant ITCs in MG. The highest cytotoxicities using 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay against MCF-7 (IC50 of 32.44 ± 1.64 μg/mL) and HepG2 (IC50 of 28.58 ± 1.04 μg/mL) after 72 h exposure were found in MG from plasma-treated seeds at 23 kV and MG from control seeds, respectively. However, MG from plasma-treated seeds at 21 kV exhibited the highest antiproliferative effect against MCF-7 (IC50 of 23.23 ± 0.23 μg/mL) and HepG2 (IC50 of 20.44 ± 0.56 μg/mL) for 14 days and also the most potent antimigratory effect. MG from cold plasma inhibited MMP-9 protein expression in both cancers indicating antimigratory property. MG from cold plasma also significantly reduced MMP-9 mRNA expression in both cancers when compared to the control and untreated cells. In conclusion, cold plasma treatment on seeds seemed to be an innovative tool to enhance ITC, TPC, TFC and anticancer properties of MG microgreens for better health implications. © 2021 Friends Science Publishers
