A study of bacterial cellulose confined ionic liquid and deep eutectic solvent gel materials
Authors:   , Smith Chip Joseph II
Published: April 2021

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Pollutants have become more prevalent in the air, water, and ground, necessitating the development of technologies that would help, limit, reverse, monitor, measure, and recycle prevalent pollutants. Ionic liquids (ILs), or molten salts that are liquid at or below 100[degrees]C, as well as deep eutectic solvents (DESs), a mixture of a hydrogen bond donor with a strong hydrogen bond acceptor that remains liquid upon cooling, have been popularized as greener alternatives in industry. These liquids tend to have large electrochemical and thermal windows, a very small vapor pressure, and can be fine-tuned for many applications. The liquid state of ILs and DESs makes them quite useful in their application but complicates their handling. Ionogels and eutectogels enable the liquid-like dynamics of these solvents while adding a pseudo-solid like character that makes for ease of handling. Herein, a new group of confined ILs and DESs within a cellulosic matrix called bacterial cellulose iono/eutecto gels are produced that are shown to be applicable to analyte detection and are studied for a better understanding of the dynamics within the gel. These intriguing gels are flexible, transparent, size-tuneable, shape-tuneable, amenable to incorporation of dyes or other functional material, and capable of confining 99 wt.% of a solvent with little leakage from the gel. These materials affect the crystallinity of cellulose little, while the liquid presents a diffusional change that stems from restructuring of the fluid. These gels are capable of detection of ammonia, hydrogen sulfide, and temperature. Given their properties, iono/eutecto gels offer use in applications, such as electrochemical devices, wound healing, drug delivery, and carbon capture/separation membranes.
Technology ethics in the public schools system : developing a technology ethics assessment tool through policy analysis at the secondary level
Authors:   , Alsup Jeremy
Published: April 2021

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Technology ethics seeks to identify the ways in which individuals and organizations might develop and sustain optimal relationships with the various technologies in their personal and professional lives. Secondary public schools have considered technology primarily through only a few very important but rudimentary lenses. The problem of practice was grounded in the ability and willingness of public schools to respond to the changing technological landscape in a way that was timely and meaningful. This study followed an exploratory sequential design and was two pronged: first, it investigated the ways public high schools supported technology ethics through their technology policies at the district and building levels; second, it developed a technology ethics assessment tool.
A qualitative case study of how an English language program at a U.S. university prepares Chinese students for U.S. undergraduate programs and communicative competence
Authors:   , Wang Mingming
Published: April 2021

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Chinese students account for about one-third of the international students at U.S. universities from 2013 to the present year 2020; however, many of them, after their arrival, feel it is difficult to fit into U.S. college learning environments. This study focused on how to get Chinese students ready for U.S. undergraduate programs. A qualitative case study method was utilized, and the case was the Intensive Language Program (ILP), a full-time program of an English language center at a Midwestern public university that is designed to support international students. Using theoretical frameworks on college readiness (Conley, 2010a, 2014b) and communicative competence (Canale and Swain, 1980, 1983), I explored how ILP prepared Chinese students for U.S. undergraduate programs in general, and I paid particular attention to how ILP improves Chinese students' communicative competence. My specific research questions were: 1. How do ILP teachers and leaders prepare students for U.S. undergraduate programs? 2. How do Chinese students who have finished the ILP program perceive ILP and how well it has prepared them for U.S. undergraduate programs? 3. How does ILP enhance Chinese students' communicative competence? The findings demonstrated that the ILP program provided valuable and comprehensive support to Chinese students in five overarching components: Think, Know, Act, Go, and Talk. Specifically, ILP added five great values to Chinese students: research, MLA and APA, writing, transition, and presentation. However, as they started their undergraduate program learning, Chinese students also shared two greatest needs: reading and the U.S. History course. The results are significant to the practices of the U.S. English language centers and international schools in China.
Testing the limit : term limits and their unintended consequences
Authors:   , Butcher Jordan
Published: April 2021

Term limits have been in place for over 20 years; we know that term limits matter, but not to what extent.Term limits vary widely across the states that have them, impacting the structure of legislative institutions and relations with other branches of government. This study is the first comparative study assessing differences across term-limited states using both individual and aggregate data. I present original datasets, as well as 101 interviews with state legislators to assess the long-term effects of term limits. This study reveals that while term limits have brought changes the institution has largely adapted to these changes.
Refining school mental health screening using mixture modeling : evaluation for use in applied settings
Authors:   , Hodgson Caroline G.
Published: April 2021

Universal socioemotional and behavior screening procedures continue to gain momentum and adoption in schools; however, a major research-to-practice gap remains in translating these data into meaningful interventions for identified students. Despite advances in methodology in school psychology research, parallel efforts have not been made to translate screening data into highly individualized, data-based interventions. The current study sought to apply person-centered analytic strategies to an existing youth mental health screening tool (EIS-Student; Reinke et al., 2020) to determine the extent to which empirically-derived latent subgroups could reveal clinically relevant conclusions in universal screening data. The sample was drawn from existing universal screening data from fall 2018 EIS-Student participants across nine high schools in a single Midwestern county (n = 5,860). Results revealed a stable 7-factor structure for the EIS-Student as well as a 5 latent profiles. Profiles corresponded with meaningfully different scores on subscales of mental health risk from the EIS-Student, and significant relationships were observed between profile membership and academic and behavioral outcomes. Characteristics of each profile are discussed for possible clinical conceptualization and applications within a socioemotional screening program. Implications for universal screening efforts are discussed, including the use of mixture modeling to identify subgroups of student need, the value of person-centered analyses in school intervention decision-making, and considerations for key stakeholders in applied contexts.
The investigation of the self-efficacy of special education teachers who teach mathematics to English language learners with disabilities
Authors:   , Kamuru Jessica Collins
Published: April 2021

Of the English Language Learners (ELLs) in USA K-12 schools, 665,000 are identified as having a disability. In mathematics, ELLs with disabilities have significantly lower outcomes than English dominant, and non-disabled peers. Numerous studies over four decades have linked student outcomes to teacher self-efficacy (i.e. belief in ability to perform a task for expected outcomes). Considering many ELLs with disabilities receive mathematics instruction from special education teachers, there are questions about the self-efficacy of these teachers to provide quality instruction, since there are few studies focused specifically on preparing or supporting special education teachers to teach mathematics to ELLs with disabilities. The purpose of this dissertation is to examine in-service special education teachers' overall self-efficacy in teaching mathematics in teaching any student with a disability and in teaching ELLs with disabilities in culturally and linguistically responsive ways. One hundred seventeen special education teachers from 9 states were recruited for this study which utilized surveys and follow up interviews. Six participants, chosen for having low or high self efficacy in teaching mathematics to any student with a disability or in teaching mathematics to ELLs with disabilities, were interviewed about factors which were helpful or harmful to their self-efficacy. Themes from the data included (a) teacher preparedness, (b) student characteristics, (c) teaching pedagogy, (d) building culture, (e) overall teacher disposition and (f) culturally responsive pedagogy.
Strategies for metal colloidal nancrystal synthesis in sustainable media
Authors:   , Bhawawet Nakara
Published: April 2021

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Over the past decades, the Green Chemistry and Sustainability concept has aroused researchers to denounce their traditional ways of thinking regarding chemical processes to address the challenges relevant to global environmental concerns. The concept has demonstrated how fundamental scientific methodologies can protect human health and the environment in an economically beneficial manner. In academia and industry, the use of green solvents, such as water, supercritical fluids, ionic liquids (ILs) and deep eutectic solvents (DESs), has then become desirable in chemical processes. In the field of green nanochemistry, ILs and DESs have acquired courtesy as sustainable media for nanomaterials synthesis. There have been attempts to employ such eco-friendly fluids to synthesize, and additionally, control size and shapes of nanomaterials, where the field has been gaining intense interests as the morphology dictates the properties and functionalities of such nanomaterials. This dissertation reports strategies for metal colloidal nanocrystal synthesis in sustainable media and aims to build a foundation for understanding how to tailor eco-friendly IL and DES fluids to control the growth of metal nanocrystals. Chapter 1 explores research reporting strategies used for metal colloid synthesis in ILs and DESs. In Chapter 2, we have developed a strategy to replace a common organic solvent with an IL to prepare monodisperse gold nanoparticles (AuNPs) by a very fast microwave method. The pyrrolidinium IL used in the work demonstrates its capability to be efficiently recovered and reused for carrying out nanoscale synthesis iteratively. The work highlights the incompatibility of imidazolium ILs for the select nanoscale synthetic strategy. For Chapter 3, we have demonstrated a control over nanoparticle size and shape generated at an aqueous-organic interface. We have shown that an interfacial photoreduction leads to the production of spherical and wire-like nanostructures, respectively, when the IL employed involves a coordinated and non-coordinated IL anion, respectively. Next, Chapter 4 has focused on exploitation of a purposefully designed IL-inspired surfactant, acting dually as a reducing and stabilizing agent, for facile and controllable AuNP formation. The reported synthetic method is simple and rapid, using only a gold precursor and the surfactant. Coinage AuNPs can be obtained very fast, while predominantly triangular-shaped AuNPs can also be achieved by tuning parameters, such as the ratio of surfactant to the gold precursor, temperature, implementing a time delay before heating, and an addition of a directing agent. Finally, Chapter 5 outlines zwitterionic deep eutectic solvents (ZDESs) as novel media for metal nanocrystal synthesis, to expand portfolio of available DESs as the field is relatively new compared to that of IL.
Use of geographic information systems and remote sensing as automated tool for variable rate irrigation prescriptions
Authors:   , Nguyen Anh Thi Tuan
Published: April 2021

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Economic as well as water shortage pressure on agricultural use of water has placed added emphasis on efficient irrigation management. Center pivot technology has made great improvement with variable rate irrigation (VRI) technology to vary water application spatially and temporally to maximize the economic and environmental return. Proper management of VRI systems depends on correctly matching the pivot application to specific field temporal and areal conditions. There is need for a tool to accurately and inexpensively define dynamic management zones, to sense within-field variability in real time, and control variable rate water application so that producers are more willing to adopt and utilize the advantages of VRI systems. This study included tests of the center pivot system uniformity performance in 2014 at Delta Research Center in Portageville, MO. The goal of this research was to develop MOPivot software with an algorithm to determine unique management areas under center pivot systems based on system design and limitations. The MOPivot tool automates prescriptions for VRI center pivot based on non-uniform water needs while avoiding potential runoff and deep percolation. The software was validated for use in real-time irrigation management in 2018 for VRI control system of a Valley 8000 center pivot planted to corn. The water balance model was used to manage irrigation scheduling. Field data, together with soil moisture sensor measurement of soil water content, were used to develop the regression model of remote sensing-based crop coefficient (Kc). Remote sensing vegetation index in conjunction with GDD and crop growth stages in regression models showed high correlation with Kc. Validation of those regression models was done using Centralia, MO, field data in 2016. The MOPivot successfully created prescriptions to match system capacity of the management zone based on system limitations for center pivot management. Along with GIS data sources, MOPivot effectively provides readily available graphical prescription maps, which can be edited and directly uploaded to a center pivot control panel. The modeled Kc compared well with FAO Kc. By combining GDD and crop growth in the models, these models would account for local weather conditions and stage of crop during growing season as time index in estimating Kc. These models with Fraction of growth (FrG) and cumulative growing degree days (cGDD) had a higher coefficient of efficiency, higher Nash-Sutcliffe coefficient of efficiency and higher Willmott index of agreement. Future work should include improvement in the MOPivot software with different crops and aerial remote sensing imagery to generate dynamic prescriptions during the season to support irrigation scheduling for real-time monitoring of field conditions.
Machine-aided analysis of vote privacy using computationally complete symbolic attacker
Authors:   , Eeralla Ajay Kumar
Published: April 2021

Security protocols employ cryptographic primitives such as encryption and digital signatures to provide security guarantees of confidentiality and authenticity in the presence of malicious attackers. Due to the complexities of cryptographic primitives, subtle nature of the security guarantees and asymmetry of communication over the internet, their design tends to be error-prone. Thus, formal methods are often used to establish whether the protocols actually achieve their guarantees. The analysis can be either carried out in the Dolev-Yao model, where the cryptographic primitives are assumed to be perfect, and the attacker tries to exploit the logical errors to compromise the security of the protocols or in the provable security model, where the attacker can, in addition, break the cryptographic primitives with negligible probability. The provable security model provides better guarantees. We consider formalizing and verifying the security property of vote privacy for electronic voting protocols in the provable security model. As an example, we consider analyzing the FOO electronic voting protocol introduced by Fujioka, Okamoto, and Ohta. Several automated analyses have been carried for the FOO protocol in the Dolev-Yao model, and the protocol is secure in the Dolev-Yao model. The protocol uses commitments, blind signatures, and anonymous channels to achieve vote privacy. The Dolev-Yao analyses also assume the existence of perfectly anonymous channels. We carried out the analysis of the security protocol using the Computationally Complete Symbolic Attacker (CCSA) technique, which allows the establishment of proofs of security guarantees using deduction in first-order logic. Unlike the Dolev Yao analyses of the protocol, we assume neither perfect cryptography nor existence of perfectly anonymous channels. We model the anonymous communication using a mix-net server who is responsible for checking if the received messages are distinct and outputting the decrypted messages in a lexicographic order. Our analysis reveals new attacks on vote privacy including an attack that arises due to the inadequacy of the blindness property of blind signatures and a Dolev-Yao style attack that arises due to the modeling of the anonymous communication as a mix-net server. With additional assumptions and modifications of the protocol, we were able to show that the protocol satisfies vote privacy in the sense that switching votes of two honest voters is undetectable to the attacker. In order to achieve higher assurances, we mechanized the CCSA technique in Coq, an interactive theorem-prover [BC04, PdAC+17] developed using the specification language Gallina. We demonstrate the effectiveness of our mechanization with the verification of authentication and secrecy guarantees of the Authenticated Die Hellman key exchange protocol. Finally, we prove the key lemmas of the proof of voter privacy for the FOO protocol in Coq.
Predicting the structure and energetics of protein-ligand interaction
Authors:   , Ma Zhiwei
Published: April 2021

Molecular docking has been a crucial component and remains a highly active area in computer-aided drug design (CADD). In simple terms, molecular docking uses computer algorithms to identify the "best" match between two molecules, a process analogous to solving three-dimensional jigsaw puzzles. In more rigorous terms, the molecular docking problem can be defined as predicting the "correct" bound association state for the given atomic coordinates of two molecules. Docking is an important tool for structure and affinity predictions of molecular association, which would lead to the mechanistic understanding of the physicochemical interactions at the atomic level. Protein-small molecule (referred to as "ligand") docking, in particular, has broad application to structure-based drug design, as drug compounds are usually small molecules. In this dissertation, I present my studies on protein-ligand docking. In the background introduction, I reviewed the docking methodology and the key recent developments in the field. Next, I applied an ensemble docking algorithm onto 14 protein kinases to study ligand selectivity, a major issue for the development of kinase inhibitors as anticancer drugs. In Chapter 3, I developed a web server for automated, in silico screening of multiple targets for a given ligand query. Finally, I integrated the new methods for protein-ligand binding mode prediction and applied the integrated method to a large-scale, blind prediction competition named Continuous Evaluation of Ligand Pose Prediction (CELPP).
Testing the efficacy of self-determination theory as a counter-propaganda interdiction tool
Authors:   , Wilbur Douglas S.
Published: April 2021

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This dissertation experimentally tests a new theoretical approach to resistance to persuasion in the context of extremist recruitment propaganda. This study leveraged the self-determination theory (SDT) of human motivation, adapting it for usage in a strategic communication context. It was proposed that a new type of counterpropaganda could be employed to interdict the effects of propaganda at the psychological level. The SDT mechanism involved was to bolster a person's sense of autonomy, which would thereby trigger resistance to controlling propaganda messages. A mixed design repeated measures experiment was conducted on (N = 387) Caucasian participants from a Mechanical Turk online panel. The experiment divided participants into three conditions: Psychological reactance support message, autonomy support message and a control condition. Each participant saw and assessed the same two extremist propaganda posters on the dependent variables: state psychological reactance, state autonomy, state competence and message credibility. The results revealed that the autonomy support message was particularly effective at reducing propaganda message credibility and increase perceptions of state autonomy. Also, of considerable significance were that the positive effects of the autonomy support message were sustained over time through the administration of both propaganda posters. This paper yields an import theoretical development for SDT as an expansion into human communication and persuasion theory. It also yields practical benefits by providing some initial evidence into a potential valuable counterpropaganda tool that can be employed as strategic communication on a mass level.
The senatorial career of George Graham Vest
Authors:   , Dawes Marian Elaine
Published: April 2021

G. G. Vest is known to most people, if at all, as the author of the famous eulogy on the dog. To a small group, he is known as the "Senator of two Republics" but to many he is known not at all. His work as a United States Senator from Missouri has received little attention. The very few accounts of his life are brief and inadequate. Sources are scarce as to his early life, hence this study is necessarily limited to his Senatorial career, although mention is made of his earlier activities. Rather than give a superficial sketch of his whole Senatorial career, it has seemed best to limit this paper to his most important work during twenty-four years in the Senate from 1879 to 1903. It is hoped that this study will be of value to all interested in Vest and his service to Missouri.--Preface.
The adjunctification of United Methodist part-time local pastors : a case study of part-time local pastors in the Mountain Sky Conference of the United Methodist Church
Authors:   , Gearhart Amy L.
Published: April 2021

The issue this dissertation addresses is that the fastest growing population of clergy leaders in The United Methodist Church (UMC) are local pastors who are generally not seminary degreed, ordained, or guaranteed employment. And yet, the employment and effectiveness of these local pastors, primarily part-time, is not researched or understood in the context of leadership needs in the 21st century Church. To address this problem, the purpose of this qualitative case study is to understand the unique professional experiences and labor conditions of part-time local pastors (PTLP's) in isolated, rural, and declining communities within the Mountain Sky Conference (MSC) of The UMC. To gather data, artifact review, demographic surveys, and Zoom interviews were conducted with eight part-time local pastors from the Mountain Sky Conference. The data lead to the following themes: types and unique leadership of PTLP's, unique contextual labor conditions, and professional resources needed. These themes are useful for understanding that many of the professional and institutional benefit systems in which PTLP's operate are forged and framed for full-time, lifelong ordained clergy. They need to be adjusted for the unique types of PTLP's and their unique ministry settings.

Corequisite mathematics education at Missouri community colleges
Authors:   , White Trisha
Published: April 2021

In an effort to raise graduation rates, the Missouri Department of Higher Education and Workforce Development directed public institutions to establish policies and create corequisite support structures to allow some underprepared students to take entry-level mathematics courses without first completing non-credit remedial courses. The present study explored the variety and effectiveness of corequisite structures implemented at 12 independent public community colleges in Missouri. Using a pragmatic parallel mixed method research design, this study used highly structured interviews and data from the Enhanced Missouri Student Achievement Study to address the research question: Which corequisite structures and policies have produced significant increases in persistence rates and completion rates of entry-level mathematics courses at community colleges in Missouri? This study described the unique structures and policies implemented at the colleges and using a chi-square test for homogeneity, compared the statewide and college persistence rates and completion rates of entry-level mathematics courses for students beginning in Fall 2014 and Fall 2018. The findings indicated that the statewide persistence rates increased but the increase was neither widespread nor consistent amongst the 12 individual colleges in the study; however, the increase in completion rates of entry-level mathematics courses was widespread and consistent with 11 of the 12 colleges seeing statistically significant increases. The study identified four conceptualizations of corequisite supports and noted that colleges allowing underprepared students greater access to non-STEM pathway courses with corequisite support saw the highest completion rates of entry-level mathematics courses.

Fiscal rules e decisione di bilancio
Authors: Ibrido Renato
Published: April 2021

Il contributo individua due fattori di trasformazione della originaria costituzione eco-nomica italiana, i quali affondano le loro radici culturali nei filoni del fiscal constitutionalism e dell'ordoliberalismo: da un lato l'incorporazione di fiscal rules in fonti rigide e di rango sovraordinato, anche per effetto del processo di integrazione europeo; dall'altro lato, l'incremento del tasso di razionalizzazione delle regole costituzionali sulla formazione della decisione di bilancio. Alla luce di tale evoluzione, il contributo si interroga sulla possibilità di una diversa organizzazione delle regole fiscali e di bilancio, la quale consenta di recuperare e saldare due principi che nell'impianto della Costituzione italiana fanno sistema: i principi di "responsabilità finanziaria" e di "responsabilità politica".

Niels Thygesen: An Academic in the Making of European Monetary Union
Authors: Maes Ivo , Péters Sabine
Published: April 2021

Niels Thygesen (born 1934) played for nearly five decades an influential role as a policy orientated academic, especially in the process of economic and monetary integration in Europe. He is especially known as a member of the Delors Committee and as the first Chair of the European Fiscal Board. As part of a re-search program on collecting memories, this paper publishes the results of several interviews with him. His early life offers insightful observations on the develop-ment of the economics profession in the postwar years (he was close to Nobel Prize laureates as Franco Modigliani and Milton Friedman). Thygesen's involvement with the process of European monetary integration really started in 1974 with his membership of the Marjolin Committee (which provided an assessment of the failure of the 1970 Werner Report). Since then he has been involved in a multitude of committees and initiatives, like the OPTICA groups, the All Saints Day Manifes-to, the Committee for Monetary Union in Europe (an initiative of Giscard and Schmidt) and the Euro50 Group.
Central Corneal Thickness in Ocular Hypertension Patients in Sanglah General Hospital Bali
Authors: Suryaningrum I Gusti Ayu Ratna , Kusumadjaja I Made Agus , Utari Ni Made Laksmi
Published: April 2021

Ocular hypertension (OH) is a risk factor in glaucoma and modifiable in its early stages. Goldmann applanation tonometer (GAT) is still the gold standard in measuring intraocular pressure (IOP) which is an important parameter in diagnosing and managing glaucoma. Several factors can affect the accuracy of the GAT, one of them is the thickness of the central cornea. This descriptive study was intended to describe the central corneal thickness (CCT) characteristics of the OH patients. The study was conducted at Eye Clinic - Sanglah General Hospital Denpasar which involved 32 patients with 46 eyes diagnosed with HO in 2018. The mean age of subjects was 43.98 (± 17.92), men had a larger proportion (68.1 %). Sixty-six per cent of patients were diagnosed with bilateral OH. In this study, the mean central corneal thickness in HO subjects was 573.81 ± 33.46 μm. The patients' median vertical cup to disc ratio at the time of diagnosis was 0.33, with a mean visual acuity of 0.85. The median value of IOP at the first time of examination was 24.47 mmHg.Central corneal thickness is known to have a positive correlation with IOP, thus affecting the accuracy of IOP measurements. The thicker central corneal thickness will lead to overestimation of the IOP and the thinner one will cause underestimation.

Citizenship in Europe: The Main Stages of Development of the Idea and Institution
Authors:   Jagiellonian University in Kraków, Trzciński Krzysztof
Published: April 2021

This paper identifi es and synthetically demonstrates the most important steps and changes in the evolution of the idea and institution of citizenship in Europe over more than two thousand years. Citizenship is one of the essential categories defi ning human status. From a historical perspective, the idea of citizenship in Europe is in a state of constant evolution. Therefore, the essence of the institution of citizenship and its acquisition criteria are continually being transformed. Today’s comprehension of citizenship is different from understanding citizenship in Europe in earlier epochs of history. In some of them, the concept of citizenship existed only in the realm of ideas. In others, the idea materialised, and membership in the state (or city) and civic rights and obligations found a formal, legal expression. The formation of the idea and institution of citizenship is a long and multi-phase process.

— Sleep-wake cycle is the most evident 24 hour rhythms observed in humans. This circadian variation is a normal biological clock. The physiological phenomenon, however has been able to explain the onset of cardiac events that also tend to occur during certain time of day. It has been known that there is a tendency for major cardiovascular episodes to occur during the mid-morning hours. With the advent of ambulatory blood pressure monitoring, the fluctuations of blood pressure throughout the day are able to be captured. This is called blood pressure variability (BPV). The factors affecting BPV include age, sex, physical activity, mental activity, behavioural and environmental. Recent studies have shown that high BPV is associated with target organ damage, in particular cardiovascular and coronary artery diseases. In the effort to explain the mechanisms related to these complications out of excessive BPV, several studies explored the role of history of family with hypertension, hyperglycaemia and hyperlipidemia towards developing pre-existing condition that lead to high BPV.
Stem Cell Therapy in Treating Type 1 Diabetes Mellitus –Potential and Ethical Issues.
Authors: Abdullah Nursuaidah , Elias Marjanu Hikmah
Published: April 2021

Type 1 diabetes (T1D) is a deficiency in insulin production which is mainly due to loss of ?-cell pancreatic islets. Patients with T1D need to be given exogenous insulin regularly. While improvements in the delivery of insulin and glucose monitoring methods have been effective in improving patient safety, insulin therapy is not a cure and is often associated with complications and debilitating hypoglycaemic episodes. Meanwhile, pancreas or islet transplantation as a gold standard only promises temporary freedom from exogenous insulin and suffers from issues of its own. Stem cell therapy may provide a more permanent solution, given stem cells’ immunomodulatory characteristics and ability to self-renew and distinguish into specific cells. In this sense, the therapeutic potentials of stem cells are addressed in this study. These stem cells cover a wide range of treatments for T1D including embryonic stem cells, induced pluripotent stem cells, bone-marrow derived hematopoietic stem cells and multipotent mesenchymal stromal cells. The challenges faced by the current stem cell transplant in T1D treatment and Islamic viewpoints regarding ethics in stem cell research and therapy are also discussed. In conclusion, stem cell therapy offers a safe and efficient alternative treatment for T1D. However, besides the fatwa from Fatwa Committee of Selangor, the lack of Malaysian stem cells ethics should be further addressed.
Different Type of Face Masks and Their Protection Against Covid-19

Coronavirus diseases 2019 (COVID-19) have become a major pandemic and a gruesome burden worldwide. The infection is easily spread through respiratory droplets from infected individuals during coughing, sneezing or talking. People in their vicinity, within 1-meter distance, can get infected by breathing contaminated air and touching the contaminated surfaces or hands. WHO encouraged the use of facemasks in the community, together with regular hand washing with soap and social distancing to prevent the transmission of COVID-19. However, with the many types of facemasks available in the markets, it remains debatable as to which ones are the most effective in curbing the transmission of the disease. This paper reviews available literature on the types of face masks, their effectiveness in filtering droplets and the advantages and disadvantages of using disposable and fabric masks. As found out, the most superior mask is the N95 type, with a filtration rate of 95% of 0.3 micron particles. However, for respiratory droplets, which particle size is from 5 to 10 microns, a surgical mask is adequate with a filtration rate of 90% of 3 micron particles. Due to disposal and cost concerns, surgical masks are recommended to be used only by health care workers. Three-layer cotton masks offer almost the same filtration rate as surgical mask and are recommended by WHO to be used in the community to prevent the transmission of COVID-19. Surgical masks and 3-layered cotton masks are effective in preventing droplet transmission from infected to healthy individuals. To prevent COVID-19, the public should be reminded continuously on the proper use and disposal of masks, regular hand washing and physical distancing.
