Role of metformin in prevention and prognosis of breast cancer
Authors: Binte Saleem Minahil , Fatima Sarah , Ali Khan Zoha
Published: June 2022

Dear Editor,
Metformin is a hypoglycemic drug of the class biguanides used as the first-line treatment for type 2 diabetes mellitus (T2DM). The drug acts by inhibiting hepatic gluconeogenesis, decreasing intestinal absorption of glucose and circulating insulin. It has also been suggested that the drug indirectly increases insulin sensitivity by increasing peripheral glucose utilization. Data from the World Health Organization (WHO) shows that breast cancer (BC) is the most prevalent cancer in women, with an incidence of 1.7 million cases in 2012 (25 % of all female cancers). It is the fifth leading cause of death from cancer overall.1
A clinical trial conducted in 2019 elaborated that metformin altered host metabolism proving to be a substitute for a fasting-like mechanism that affects cancer cells' metabolism and growth environment of cancer cells including an increase in beta-OH-butyric acid (BHBA).2
It was further corroborated by a research that found an inverse relationship between metformin and BC. This is accomplished by boosting the activity of AMP-dependent protein kinase, which suppresses the mTOR-associated oncogenic signalling pathway. This induces S phase arrest and apoptosis in triple-negative breast cancer cells. Data from 18,527 participants brought about 2,680 participants who used metformin at least three months before the diagnosis of BC. A multivariate study showed that this was negatively associated with BC risk (0.821, 0.726-0.912, p=0.002).3
A favourable response on disease-free survival and overall survival in BC patients with T2DM. The number of CD8+ tumour-infiltrating lymphocytes (TILS) has been increased with the use of metformin engendering anti-carcinogenic effects.4
In the last 15 years, we have seen a drastic change in the demographics of BC, with an estimated increase of 70.7 to 130.6% in 2020 and 2025 relative to 2015 in the 30-34 age group in Pakistan.5 There has been a significant increase in T2DM along with increased use of metformin for its treatment which thus raises a question about the efficacy of the drug in a neoadjuvant setting for BC on Pakistani society. Further research, especially clinical trials, needs to be conducted in Pakistan including but not limited to a correlation of metformin use and incidence of BC.

Authors: Ezadeen Shamil , Alwattar Auday H
Published: June 2022

Abstract. Security is the study of encryption and decryption, data hiding, potential attacks, and performance evaluation. Many algorithms perform this purpose. Blowfish is a symmetric block cipher that uses the Feistel network. Although several works employed the Blowfish algorithm for the security of the cloud, there is still no article that lists previous studies. Cloud computing is the transmission of computer services such as servers, storage, databases, networking, software, analytics, and intelligence through the Internet ("the cloud") in order to provide faster innovation, more flexible resources, and cost savings. The most common issue with cloud computing is information security, privacy, confidentiality, and how the cloud provider ensures these services. This paper includes a survey  of most previous works that were concerned with using the Blowfish algorithm in achieving cloud security

Walid Raad: The Art of Fiction in a Post-Truth World
Authors: Oosterom Sander
Published: June 2022

Son yıllarda çağdaş sanatta kurgusal stratejilerde bir artış görülmektedir. Genellikle “parafiction” olarak adlandırılan bu sanat eserleri, gerçek hayattaki varlıklar olarak algılanan ve işlev gören hayalî kişiler ve olaylardan oluşan bir kurgu sunar. Çağdaş sanatın önde gelen temsilcilerinden biri olan Lübnanlı sanatçı Walid Raad, bilginin inşasında çeşitli medyaların epistemolojik istikrarsızlığını sorgulamak için uzun süredir kurgusal stratejilere yönelmektedir. “Tarafsız” medyanın katıldığı söylemsel çerçevelere özellikle dikkat çeken sanatının amacı, hakikati yapıbozuma uğratmak değil, yerelleştirmektir. Bu makalede, gerçek ile kurgu arasındaki ayrımı bilinçli olarak bulanıklaştırarak, Raad’ın sanatının hakikat sonrası dönemin estetik ve epistemolojik yapısını yansıttığını savunuyorum. Aynı zamanda, onun çalışmasında kurgunun epistemolojik rolünün bir değerlendirmesini sunuyor ve gerçek-sonrası bir dünyada paraficti-on’ın politik önemini araştırıyorum.

Authors: TEZCAN Mehmet Murat , AKYURT Aleyna Simge
Published: June 2022

The increasing of world population, forced human beings to produce clean energy, more creative solutions have been developed to use the energy with most efficient way. Researches on this topic still working today. Nowadays, new electrical machines are invented and the currently used ones are being continue to be improved. In industry, if a survey is made according to use of electric motors, it will be seen that, induction motors used in industry average eighty percent. When viewed from the efficiency and energy quality of the interconnected system, increasing efficiency of induction motors will provide advantages for the production, transmission, distribution systems and the network. On the other hand, Permanent Magnet Synchronous Motors (PMSMs) have not windings on rotor core and much more efficient than induction motors. In this way PMSMs will save the company from spending unnecessary energy. For this reason, in this study, an industrial conventional type squirrel cage induction motor (SCIM) has been converted into a permanent magnet synchronous motor (PMSM) for improve the overall efficiency. For improving the efficiency in design and production, induction motor’s stator core will not change. Only squirrel cage rotor core of induction motor will change with PMSM in rotor design production stage. As a result of this conversion, various electromechanical parameters have changed and improved. Electromechanical modification process has been provide better energy density and power density for this motor. As a result of the research, the cost of modification process will be amortized in usage. In this way, conventional type induction motor (IM) that dominates the vast majority of the industry is converted into PMSM, it is seen that energy efficiency and energy quality will increase.

Migrant women inside the spiral of sexual and gender-based violence: A contextual assessment
Authors: PEKASIL Ayşe Nur
Published: June 2022

The risk of sexual and gender-based violence (SGBV), increases significantly for women in a war/conflict context and forced migration process. However, SGBV exposure by migrant women is only considered as the unfortunate outcome of the war. This situation makes the appearance of SGBV even more obscure and makes it invisible. The aim of this review is to contextually (war/conflict context, journey, and destination country) evaluate the appearances of SGBV, which is the continuation of the conflict to which forced migrant women are exposed, and to discuss the contextual mechanisms that feed the SGBV spiral. As a result, SGBV to which forced migrant women are exposed has a spiral structure, but the appearances of SGBV are complex, interactive, transformative, and are fluidly and dynamically constructed with the contextual parameters in which SGBV action occurs. This construction process determines the direction of outcomes, needs, and interventions.

The aim of this study was to investigate the impacts of COVID-19 on the consumption patterns of vegetarians and non-vegetarian populations, mainly on animal-based products. A cross-sectional, questionnaire-based survey was conducted among the urban and peri urban populations of Bengaluru, Karnataka during October to November of 2020 through electronic mode. The data was collected from 837 (54.2% non-vegetarian and 54.2% vegetarians) participants. Significant change in the number of family members before and during the COVID lockdown was observed. The egg and chicken consumption had drastically increased among the non-vegetarians whereas, among the majority of the vegetarians, no change in milk consumption but a considerable increase in curd and buttermilk, paneer/cheese, and ghee/butter consumption was observed. Both non-vegetarian and vegetarian consumers had shifted to online delivery apps for purchasing products during the pandemic. The majority of the non-vegetarians (80.84%) and vegetarians (55.09%) opined that the price of meat and milk products increased during the pandemic. The pandemic had an effect on consumption among non-vegetarian and vegetarian consumers but increased accessibility of products through deliveries or pick-up points at various locations might have reduced the price and also induce the consumption of these products.

Published: June 2022

Rural to urban migration has become an unavoidable event in the last 25 years with increased industrialization, growing service industry, better food security, access to improved healthcare and educational facilities in the cities apart from the rising ambitions of the youths. Agriculture always had a vital role in a village economy but this sector has not been financially rewarding in the past few decades and as a consequence of which, young generations from villages are leaving their family enterprises and migrating to cities for acquiring modern education and skills to secure a job in private sector. The study was conducted to find out the migration behaviour of rural youth in Bhiwani and Hisar districts of Haryana. A sample size of 192 rural youths i.e., 96 fully migrated & 96 partially migrated, were selected for the study. Findings revealed that unstable income, lesser employment, repeated crop failures were the push factors responsible for migration of rural youths. Higher wages, better jobs and better standard of livings in cities were the major pull factors motivating rural youths to migrate towards cities. Further, socio-economic & psychological variables such as age, education, farm size, non-farm skills, income expectancy, comfort expectancy, risk orientation, self-reliance & self-confidence had significantly positive correlation whereas, farm size, stimulation expectancy and affiliation expectancy had negatively significant relationship with migration behaviour of rural youth. Also, regression analysis showed that, seventeen independent variables selected for the study could explain 59.40 per cent variation in the migration behaviour of rural youths.

Published: June 2022

It is extremely difficult for people who are deaf to communicate their message to normal people. Communication becomes extremely difficult in case of an emergency, while travelling or among unfamiliar people because most people are not trained in hand sign language. We propose a voice aid system that allows deaf persons to communicate with regular people by using hand motions and gestures. This system uses motion and flex sensors, as well as a speaker unit. The circuitry that runs this system is fuelled by batteries. The system includes various pre-programmed messages such as "need help," "where is the washroom," and other common phrases that enable deaf individuals communicate basic information. The technology analyses a person's hand motions for different variants. It also has a trigger sensor to provide the impression that the person wants to activate the device and say something.

Cloud computing provides lot of benefits to enterprises to offload their data and software services to cloud saving them lot of money that has to be spent on infrastructure setup cost. Enterprises wanted to offload their data to cloud and save on their infrastructure cost. But when offloading the data security and privacy is a important concern. In this work, we focus on the search on encrypted data and provide a effective solution for the search. Searchable symmetric encryption (SSE) allows retrieval of the encrypted data over cloud. We formulate the privacy issue from the aspect of similarity relevance and scheme robustness. We observe that serve-side ranking based on order-preserving encryption (OPE) inevitably leaks data privacy. To eliminate the leakage, we propose a secure-channel free ciphertext-policy decryptable attribute-based keyword search (CP-DABKS) scheme on eHealth cloud in the Internet of Things (IoT) platform. Additionally in CP-DABKS, we employ a vector space model and homomorphic encryption. The vector space model helps to provide sufficient search accuracy, and the homomorphic encryption enables users to involve in the ranking while the majority of computing work is done on the server side by operations only on ciphertext.

ACIDENTE VASCULAR ENCEFÁLICO COMO COMPLICAÇÃO DA HIPERTENSÃO ARTERIAL SISTÊMICA E SEUS FATORES ASSOCIADOS
Authors: VICARI MARIA PAULA IDELBRANDO
Published: June 2022

Introdução: O acidente vascular encefálico pode ser classificado em isquêmico, como resultado de fornecimento insuficiente de sangue por obstrução arterial, ou hemorrágico, devido rompimento de vasos sanguíneos cerebrais. Considerada a terceira causa de morte mais frequente mundialmente, o AVE possui alguns fatores de risco, dentre eles, a hipertensão arterial sistêmica (HAS) é uma das mais significativas. Definida pelo aumento da pressão sanguínea, esta pode desencadear diversas doenças, assim como, complicar quadros previamente estabelecidos. Objetivos: A análise objetiva identificar as possibilidades de aparecimento de AVE em pacientes hipertensos, assim como, seus fatores de risco relacionados. Metodologia: Trata-se de uma pesquisa de revisão narrativa descritiva baseada em publicações científicas sobre o tema, publicadas em sua íntegra na língua inglesa nas plataformas digitais UpToDate e Scientific Electronic Library Online (SciELO) entre os anos de 2015 e 2022. Resultados e Discussão: A hipertensão arterial sistêmica (HAS) é uma doença crônica degenerativa, qual o portador pode apresentar das mais variadas complicações, principalmente cardiovasculares, sendo a formação de trombos e êmbolos devido razões como hipercoagulabilidade, um quadro bastante comum, estes são os principais fatores associados ao desenvolvimento de um AVE isquêmico por impedir suprimento sanguíneo cerebral adequado. Estima-se que 80% dos pacientes hipertensos sofrerão AVE ou IAM ao percorrer da vida, porcentagem que aumenta conforme exposição a outros fatores de risco, classificados em modificáveis como obesidade, dislipidemia, estresse, tabagismo, alcoolismo, sedentarismo e má alimentação; e não modificáveis como idade, sexo, raça e hereditariedade. Conclusão: Mesmo com o avanço farmacológico no tratamento do AVE, a melhor opção àqueles sujeitos ao desenvolvimento do quadro é a prevenção, por meio de controle da pressão arterial e alteração dos fatores de risco modificáveis. Por ser uma doença insidiosa, é necessário estar sempre atento e informado. A falta de conhecimento gera falha na prevenção de complicações devido essas patologias, a ciência do manejo adequado no diagnóstico e tratamento da lesão cerebral constitui prioridade de atendimento e pesquisa naqueles com pressão arterial elevada.
Something is Rotten in the State of America: Product Market Competition Decline in the US?
Authors: Begovic Boris
Published: June 2022

Based on available theoretical and empirical research, the paper demonstrates that although some decline in the product market price competition in the US has been observed, the non-price competition has become more intensive, therefore enhancing competitive constraints. Increased markups (although the magnitude of the change is disputed) are primarily due to investments in Research and Development and brand development, which have created a substantial increase in intangible assets and rise of fixed costs. In the environment of cost-heterogenous firms, markups are not necessarily evidence of market power, which should be associated only with negatively sloped residual demand curve. The declining share of labour in the value added and increasing income inequality cannot be explained by the ostensible decline of competition in the US product markets, but by technological progress and globalisation. Three vulnerabilities of the competition in the US are identified: killer acquisitions, common ownership, and legal barriers to entry.

The first question to be answered is related to the extent of transplantation of the institute from Saxon customs to Serbian written law. The second aim is the definition of the competence of hutman and the way he was appointed. The results indicate the Despot Stefan’s Mining Code recognized two different institutes of hutman. The first was auxiliary service to urbarar, measuring and marking the land in the procedure of granting mining concessions and after breaking one mine into another, charging a fee. He was probably appointed by tax collectors. The second one is the supervisor of a mine, entitled to collect the payment from the owners of its shares, to record it and presumably to take care of correct conducting all kind of activities in the mine. Most likely he was employed by the shareholders of the mine partnership. The linguistic, systemic, and historical interpretation is applied as well as the comparative method and regressive analysis.
BREXIT: Predicting the Brexit UK Election Results by Constituency using Twitter Location based Sentiment and Machine Learning
Authors: Usher James , Dondio Pierpaolo
Published: June 2022

After parliament failed to approve his revised version of the ‘Withdrawal Agreement’, UK Prime Minister Boris Johnson called a snap general election in October 2019 to capitalise on his growing support to ‘Get Brexit Done’. Johnson’s belief was that he had enough support countrywide to gain a majority to push his Brexit mandate through parliament based on a parliamentary seat majority strategy. The increased availability of large-scale Twitter data provides rich information for the study of constituency dynamics. In Twitter, the location of tweets can be identified by the GPS and the location field. This provides a mechanism for location-based sentiment analysis which is the use of natural language processing or machine learning algorithms to extract, identify, or distinguish the sentiment content of a tweet (in our case), according to the location of origin of said tweet. This paper examines location-based Twitter sentiment for UK constituencies per country and aims to understand if location-based Twitter sentiment majorities per UK constituencies could determine the outcome of the UK Brexit election. Tweets are gathered from the whisperings of the UK Brexit election on September 4th 2019 until polling day, 12th December 2019. A Naive Bayes classification algorithm is applied to assess political public Twitter sentiment. We identify the sentiment of Twitter users per constituency per country towards the political parties’ mandate on Brexit and plot our findings for visualisation. We compare the grouping of location-based sentiment per constituency for each of the four UK countries to the final Brexit election first party results per constituency to determine the accuracy of location-based sentiment in determining the Brexit election result. Our results indicate that location-based sentiment had the single biggest effect on constituency result predictions in Northern Ireland and Scotland and a marginal effect on Wales base constituencies whilst there was no significant prediction accuracy to England’s constituencies. Decision tree, neural network, and Naïve Bayes machine learning algorithms are then created to forecast the election results per constituency using location-based sentiment and constituency-based data from the UK electorate at national level. The predictive accuracy of the machine learning models was compared comprehensively to a computed-baseline model. The comparison results show that the machine learning models outperformed the baseline model predicting Brexit Election constituency results at national level showing an accuracy rate of 97.87%, 95.74 and 93.62% respectively. The results indicate that location-based sentiment is a useful variable in predicting elections.
A glance at blockchain technology and cryptocurrencies as an application

Blockchain technology, which includes cryptocurrencies such as Bitcoin, Ethereum,…etc [1,2] which has been evaluated as an investment tool by many people all over the world in recent years, needs to be examined in details, both mathematically and conceptually [8,9]. In fact, it can be said that blockchain technology, which is characterized as an accounting system and database based on distributed ledgers in its most basic form, is extremely secure in terms of copying data or attacking. For this reason, we can say that technology has a more effective security mechanism than any central state-of-the-art authoritative system used today. However, as it is almost impossible to bring all of the security, speed and cost parameters to their full extend in a system at the same time, as in any cryptosystem, the security parameter from the distributed ledger structure in blockchain technology adversely affects the speed and cost parameters. In this article, we discuss the cryptographic working principles of cryptocurrencies, which is an application field of blockchain technology, together with blockchain technology and the features and structures of the blocks contained.
Soy paraguayo

Published: June 2022

Paraguay es un país habitado por una amplia variedad de grupos étnicos. Están —por ejemplo— los distintos pueblos indígenas, los colonos menonitas, los inmigrantes europeos de los comienzos del siglo XX, o los brasileños llegados en tiempos más recientes. El documental "Soy paraguayo" recoge historias personales de 32 mujeres y hombres, de las que emerge un complejo mosaico de la realidad paraguaya en actualidad. Así mismo salen a la luz los problemas más esenciales del país: la muy desigual distribución de tierras, la deforestación desenfrenada, el uso intensivo de agroquímicos en el cultivo de la soja transgénica y el desentendimiento entre tan diferentes culturas.

Purpose: This research aims to analyze how the productive consumer is portrayed by scientific production in the Marketing area.Methods: A bibliographical research was carried out, and the data were extracted based on articles from the main journals in the Marketing area, according to the ranking developed by the Scimago Journal & Country Rank. From a qualitative research perspective, Interpretative Content Analysis was used in the study of the corpus, developing the codification and correlation of concepts exposed by the various authors.Findings: The study created a systematic review of what the authors treat, elaborate on, and reflect on the productive consumer in the scientific area of Marketing. The results discuss three theoretical fields of interpretation of the object of study: the purpose of the act of prosumption; the interaction established between consumers; and the relationship between consumers and companies.Originality: The article contributes to the field of Marketing as it develops a conceptual framework that demonstrates and interconnects academic approaches to productive consumers. In this way, the study contributes to a better understanding of the prosumer, elucidating the existence of identity relations and contributing to the promotion of new research that uses the characteristics presented or amplifies them.
Outcomes of Increased Practitioner Engagement in Edtech Development: How Strong, Sustainable Research-Practice-Industry Partnerships will Build a Better Edtech Future
Authors: Pautz Stephenson Stefani , Banks Rebecca , Coenraad Merijke
Published: June 2022

A new participatory research model, Research-Practice-Industry Partnerships (RPIP), presents a unique value proposition. Design processes have typically placed professional designers, not the end users, at the center of the work. RPIPs create an intentional feedback loop that transforms the knowledge, action, or goals of all involved parties (Baker et al., 2022). RPIP aims to create better designs for scalable technologies that both meet the needs of educators and incorporate research from the learning sciences. This yields a product more likely to be used, used appropriately, and have the desired impact for learners. Digital Promise partnered with edtech startup Merlyn Mind and the University of California, Irvine (UCI) in an RPIP. This white paper describes our engagement and suggests that this model can yield positive impacts and new learning for all participants. Surveys and interviews with participants showed that engagement was mutually valued among all parties, practitioners learned more about AI and edtech in general, and Merlyn Mind staff learned more about working with schools and educators. Practitioners also benefited from the networking and collaboration that participation in the RPIP brought and felt it helped them grow professionally.

Background: Halitosis is a malodor comes from the oral cavity and it is quite serious problem that can cause low self-esteem to a person. Main cause of halitosis is the release of volatile sulphur compounds (VSCs) produced by anaerobic bacterial activity inside the oral cavity. One of the ways to overcome halitosis is using mouthwash. Available mouthwashes in market are chlorhexidine and essential oil. Chlorhexidine is a broad-spectrum antimicrobial drug. Its roles are as an antiseptic agent, an effective bactericidal agent against all kinds of microbe, including bacteria, yeast, and virus. An essential oils mouthwash has antimicrobial effect and prevents bacterial aggregation. Its mechanisms through bacterial cell destruction, bacterial enzyme inhibition and endotoxin extraction from Gram negative bacteria that can cause halitosis. Objective: This study aimed to know comparison effectivity between chlorhexidine and essential oil contained in mouthwash in decreases of halitosis level. Methods: Experimental method is used in this study, comprised 32 subject divided into 2 group who had criteria for inclusion. Group 1 rinsed using chlorhexidine mouthwash and group 2 rinsed using essential oils mouthwash. The measurement was done before intervention, first 20 minutes, 40 minutes and 60 minutes. Results: Collected data was analyzed using Shapiro Wilk for normality test and non parametric Mann-Whitney for statistical hypothesis test. Result There was different effectiveness of chlorhexidine and essential oils mouthwashes in reducing halitosis level. Conclusion: Chlorhexidine is more effective in reducing halitosis compared to essential oils.
