Toxicity Management of Front-Line Pembrolizumab Combined With Axitinib in Clear Cell Metastatic Renal Cell Carcinoma: A Case Study Approach
Authors: Wood Laura S. , Ornstein Moshe C.
Published: February 2020

Immune checkpoint inhibitors have improved clinical outcomes in many malignancies, including renal cell carcinoma (RCC). Awareness of potential adverse events and effective management of these toxicities is critical to maximizing clinical outcomes. Pembrolizumab plus axitinib is approved as front-line treatment of advanced renal cell carcinoma (aRCC), making it the first checkpoint inhibitor and tyrosine kinase inhibitor combination approved for any malignancy. Given overlapping toxicities with this combination, the toxicity profile of each drug must be considered when assessing and managing toxicities in patients treated with pembrolizumab and axitinib. Use of online resources, including published guidelines from ASCO, the Immuno-Oncology Essentials Web site, and other organizations, can assist oncology and nononcology health care professionals to more effectively manage toxicities, maximize clinical outcomes, and improve quality of life for patients with aRCC. Herein, we describe a case of a patient with aRCC treated with pembrolizumab and axitinib, highlighting a systematic approach to toxicity management.
The Great Indian Demonetization
Authors: Lahiri Amartya
Published: February 2020

On November 8, 2016, India demonetized 86 percent of its currency in circulation. The stated objectives of the move were to seize undeclared income, to destroy counterfeit currency, to speed up formalization of the economy, and to increase the tax base. I find that the evidence over the subsequent three years suggests that the move had limited success in achieving its stated objectives. Disaggregated data suggests that demonetization did have appreciable costs in terms of lost jobs and output. However, the output costs appear to have been temporary.

Conventional physically based models have long yielded promising results, as they have been the main tool to depict the underpinnings of the physics governing the hydrological events. These models, however, suffer from certain issues such as the intense calibration time or the uncertainty in the estimation of hydrological variables. The development of the sophisticated data-driven techniques, and machine learning models in particular, combined with rapid increases in computational abilities (graphics processing units, computer clusters. etc.), has enabled hydrologists to utilize the data driven models in tandem with the well-established hydrological models to simulate miscellaneous environmental processes nimbly, and therefore circumvent the aforementioned conundrums associated with the physically based models. To this end, the present study aims at exploring a sophisticated neural network called variational Bayesian neural network, to improve the accuracy of physically based predictions such as runoff. Our neural network was able to accurately forecast the runoff rates with the mean Pearson correlation coefficient of 86.27%+0.0599 within a randomly selected subset of cells in the Brazos River Basin. As these cells are selected randomly across the basin, we exclude the possibility of biasing our neural network by any specific cell. Moreover, this work for the very first time, to the best of our knowledge, suggests a similarity-based solution to transfer the learning model developed in a basin to be deployed across a different basin. In other words, there would be no need to develop a learning model for each basin from scratch. We, instead, utilize the models learnt from the previously studied basins. We cross-validated our proposed transfer learning solution via leave-one-out strategy within the grid cells of the Brazos River basin achieving a mean Pearson correlation coefficient of 85.83%+0.0592.

Published: February 2020

The lower Eocene sediments from the classical Paleogene section exposed along the Kheu River, northern Caucasus, southern Russia are here studied. This ca. 50m thick succession is lithologically contrasting: the lower and upper parts are composed by soft marls separated by a thick Radiolaria-rich unit of non-calcareous and low-calcareous mudstones with intercalations of compact cherty layers. According to nannofossil and dinocyst biostratigraphy, the unique intercalation of Total Organic Carbon (TOC)-rich sediment (sapropelitic bed) in the lower part of the lower Eocene correspond to the Paleocene-Eocene Thermal Maximum (PETM) and a series of sapropelitic interlayers in the upper marly part of the lower Eocene succession correlates with the Early Eocene Climatic Optimum (EECO). The study of nannofossil and dinocyst assemblages enabled detailed zonal subdivision and first-order calibration of nannofossil and dinocyst bio-events during this time-span. The studied interval of the section embraces the complete succession of nannofossil zones NP9-NP13 of Martini, 1971, CP8-CP11 of Okada and Bukry, 1980 and CNP11-CNE5 of Agnini et al., 2014. By means of dinocyst stratigraphy, the succession of Apectodinium hyperacanthum, Axiodinium augustum, Deflandrea oebisfeldensis, Dracodinium astra, Stenodinium meckelfeldense, Dracodinium varielongitudum, Ochetodinium romanum/Samlandia chlamydophora and Areosphaeridium diktyoplokum zones are identified in the Ypresian part of the Kheu section.
Anomalous amplification in almost-balanced weak measurement for measuring spin Hall effect of light
Authors: Luo Lan , He Yu , Liu Xiong , Li Zhaoxue , Duan Pi , Zhang Zhiyou
Published: February 2020

In this paper, a method to measure the tiny spin splitting of the spin Hall effect of light (SHEL) using the almost-balanced weak measurement (ABWM) is presented. The ABWM technique uses two orthogonal post-selected states to record all of the information, which is a precise measurement method being different from the standard weak measurement (SWM). The theory model to describe the SHEL measurement based on ABWM is established. As results, the ABWM scheme has a larger amplification factor, reaching ∼105, which is nearly one order of magnitude higher than that of the SWM. When the post-selected angle is less than a certain value, the sensitivity and amplification factor of the ABWM scheme are higher than those of the SWM scheme, while the measurement precision and SNR of the ABWM technique are comparable to those of the SWM scheme. This research may have great potential for the precision metrology or sensing field based on the SHEL measurement.

Published: February 2020

In the study, the yttrium (Y)-doped vanadium oxide (VOx:Y) films used as the sensitive layers of microbolometers were deposited using a radio frequency magnetron co-sputtering system. The temperature coefficient of resistance (TCR) of the VOx:Y films was enhanced from −1.88%/°C to −2.85%/°C in comparison with that of the VOx films. To further improve the performance of microbolometers, the nanomesh antireflection layer was placed on the top surface of the microbolometers to reduce the infrared reflection. The responsivity, thermal time constant, thermal conductivity, absorptance, and detectivity of the VOx:Y microbolometers with nanomesh antireflection layer were 931.89 ± 48 kV/W, 4.48 ms, 6.19×10−8 W/K, 74.41% and 2.20×108 cmHz0.5W−1, respectively.

Published: February 2020

In holographic data storage systems, the quality of the reconstructed data pattern is decisive and directly affects the system performance. However, noise from the optical component, electronic component and recording material deteriorates reconstruction quality. A high noise margin decoding method developed from compressed sensing technology was proposed to reduce the impact of noise in the decoding process. Compared with the conventional threshold decoding method, the proposed method is more robust to noise and more suitable for multilevel modulation. The decoding performance with five-level amplitude modulation was evaluated by both simulation and experimentation. For the combination of Gaussian noise, Rician noise and Rayleigh noise, the proposed decoding method reduces the BER of the threshold method to one-sixth with an SNR of -1 in the simulation. In the experiment, it behaves up to 8.3 times better than conventional threshold decoding.

Published: February 2020

We applied point spread function engineering to design an optimized diffuser producing half-ring irradiance patterns satisfying two objectives: reduced peak irradiance in the focal plane, and high fidelity of the reconstructed image. Applications of these optical elements may include sensor protection or reversible diffusers. Experimental and numerical techniques were used to demonstrate three orders of magnitude of suppression of the peak irradiance. Finally, we found a general power-law trend between the Strehl ratio and the light suppression factor.

Published: February 2020

We propose and report the implementation of a multiband and photonically amplified fifth-generation (5G) new radio (NR) system based on radio over fiber technology and four-wave mixing (FWM) nonlinear effect. A piece of highly nonlinear fiber has been employed to stimulate FWM, which enables photonics-assisted RF amplification up to millimeter waves. Experimental results demonstrate a uniform and stable 15 dB ultra-wideband gain for 4G and three 5G signals in the frequency range from 780 MHz to 26 GHz, coexisting in the transport network. The obtained digital performance has efficiently met the Third-Generation Partnership Project requirements, demonstrating the applicability of the proposed approach for using fiber-optic links to distribute and jointly amplify 4G and 5G signals in the optical domain.

Ghost imaging for detecting trembling with random temporal changing
Authors: Huang Xianwei , Nan Suqin , Tan Wei , Bai Yanfeng , Fu Xiquan
Published: February 2020

The imaging environment can be destabilized for moving objects and imaging platforms, thus leading the detection to be random trembling, which is detrimental to object reconstruction. In this Letter, we experimentally investigate ghost imaging for detecting trembling with random temporal changing, and an improvement method based on the temporal property of the imaging process is proposed. It is demonstrated that this method is effective in addressing image degradation due to the trembling disturbance and obtaining a higher-quality image of the object. The results provide a promising approach to deal with image degradation caused by an unstable environment and can find potential applications for ghost imaging in remote sensing.
Social Assistance for Poverty Reduction in the EU Countries: An Aspect of Socio-Economic Sustainability
Authors: Balvociute Rasa
Published: February 2020

Abstract

Research on the impact of social assistance benefits and other socio-economic indicators on poverty reduction during 2000 – 2017 in 24 EU countries is presented in the paper. In order to assess the impact a regression analysis model of the panel data was composed by including such indicators as changes in gross total expenditure per capita, the GDP growth rate, the share of the retirement-age population, the unemployment rate of the working-age population, the long-term unemployment rate. Research findings revealed the main socio-economic indicators that have the greatest impact on changes in poverty. The economic slowdown reduced the at-risk-of poverty gap of people with the lowest income and the economic growth reduced the poverty gap with a lag of two periods (years). The overall impact of all social transfers under analysis on the at-risk-of poverty gap was insignificant. The at-risk-of poverty rate, which shows changes in the share of the most deprived population under analysis, increased when non-targeted and means-tested benefits gal geriau social transfers increased. On the basis of these findings it can be stated that, during the period under analysis, social assistance was not well-directed, i.e. did not focus on the most deprived part of the population. 

Keywords: sustainable development, social assistance benefits, means-tested benefits, the at-risk-of-poverty rate, the relative poverty gap, panel data.
Az univerzális kvantor extra tág hatókör-értelmezése

Published: February 2020

A hatókör-értelmezésre vonatkozó klasszikus generatív nézet szerint egy kvantor logikai hatóköre nem terjedhet túl azon a finit tagmondaton, amelyben az adott kvantor áll (azaz: nem vehet fel extra tág hatókört). Egyes, empirikusan ezidáig nem kellően megerősített feltételezések szerint azonban létezik egy kivételes, vonzat szerepű kötőmódú tagmondatot tartalmazó szerkezettípus, amely megengedi a benne szereplő univerzális kvantor számára az extra tág hatóköri olvasatot. Wurmbrand (2013; 2018) szintaktikai magyarázata szerint emiatt a kvantorhatókörre vonatkozó klasszikus, finit tagmondati lokalitási korlátot gyengíteni szükséges, míg Farkas–Giannakidou (1996) jelentéstani magyarázata azt állítja, hogy a kivételes hatóköri olvasat jelentéstani újraelemzésnek köszönhető.

Tanulmányunkban a jelenséget magyar anyanyelvű felnőtt beszélők ítéletei alapján vizsgáljuk. Kimutatjuk, hogy az extra tág hatóköri értelmezés (1) valóban elérhető a kritikus mondattípusban, de (2) hasonlóképpen elérhető egy a kritikustól minimálisan eltérő olyan mondattípusban is, melyre magyarázatként csak a jelentéstani újraelemzés terjeszthető ki, míg a szintaktikai lokalitási korlát gyengítése nem. Ez alapján a vizsgált extra tág hatóköri olvasatnak a jelentéstani újraelemzésen alapuló magyarázata mellett, és a kvantorhatókör klasszikus, finit tagmondat alapú szintaktikai lokalitási megszorításának a feladása ellen érvelünk.

The radish (Raphanus sativus L.) is a vegetable of the Brassicaceae family cultivated worldwide and has several medicinal properties. Its biological activities are related to various secondary metabolites present in the species, especially phenolics. Thus, the objectives of this study were the chemical analysis and evaluation of the antioxidant and antimicrobial activities of the dry extract and fractions of the fodder turnip leaves (R. sativus var. oleiferus Metzg.). Samples were analyzed by mass spectrometry and the antioxidant activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical method and the reducing power method. Antimicrobial activity was determined by the agar diffusion and microdilution methods. The total phenols were concentrated in the butanol fraction (121.27 mg GAE/g) and the flavonoids were concentrated in the ethyl acetate fraction (98.02 mg EQ/g). The ethyl acetate fraction showed the best antioxidants results, with 83.45% of free radical scavenging and 11.34% of ferric ions reduction. The analysis of antimicrobial activity showed that the dry extract had the highest average zone of inhibition against Bacillus subtilis (18.67 mm). Smaller values of the minimum inhibitory concentration for Micrococcus luteus were, and the ethyl acetate fraction showed a lower minimum inhibitory concentration (0.1 mg/ml) for that microorganism. There was a strong correlation between the antioxidant activity and the content of phenols and flavonoids. The results showed the potential antioxidant and antimicrobial activities of this extract with the ethyl acetate fraction being most promising for further studies.

This research aimed to evaluate the performance, body composition and net requirements for protein and energy in grazing Nellore steers supplemented with or without addition of lipids. Twenty-eight steers, 301 ± 5.8 kg BW, were used in the experiment. The comparative slaughter method was used, with four steers used as references. The remaining 24 steers were randomly distributed into four groups, during 180 days, according to treatment: only Panicum maximum cv. Mombasa grass; Mombasa grass with concentrated supplementation based on soybean meal; Mombasa grass with concentrate containing lipids from soybean oil; and Mombasa grass with concentrate containing lipids derived from soybean grains. The total DMI of the steers fed only the pasture did not differ (P > 0.05) from the average intake of the treatments with or without addition of lipids. There were no differences (P > 0.05) between treatments for total daily gain, carcass and non carcass for protein, energy and fat. The requirements of protein and energy did not differ (P > 0.05) among the treatments. When the pasture is of good quality, supplementation does not alter the body composition or the net requirements of protein and energy for weight gain. The supplementations with higher concentrations of lipids (oil and grain) were not enough to promote greater gains in fat and energy in carcass.

The demographic transition that occurred in Brazil brought changes in its health indicators. Integrated Continuous Care (ICC) was organized as a health care model aimed at increasing the independence and well-being of people with acute or recent functional dependence. This study aimed to describe the development and implementation of the Integrated Continuous Care in the state of Mato Grosso do Sul, Brazil. This care model utilized the principles of the National Humanization Policy, such as the extended and shared clinic, embracement, educational practices and meetings with caregivers, families, and patients, open visits, participation and autonomy of the patient and family in the construction of the Singular Therapeutic Project, and shared discharge from hospital. Assistance and support to patients who were already released from ICC must be increased in the primary health care setting to ensure continuity of recovery, better readaptation, and successful family and social reintegration. As a positive result, we set up an outpatient clinic for ICC patients who needed continuous clinical follow-up after rehabilitation. This allows patient re-evaluation, reduces re-admission rates, and maintains the domiciliary care management educational process. As an innovative approach to improving health care outcomes, ICC allows the patients to leave the hospital environment and go home on some weekends. The ICC project has enabled many advances, especially in patient-centered care and shared decision-making. The support of the São Julião Hospital administration has been vital to the success of ICC Unit treatments.

Leptospirosis is a zoonosis that affects several species of domestic and wild animals and is an important cause of economic losses in cattle in Brazil. In this study, we determined the prevalence of bovine leptospirosis in the Triângulo Mineiro region, Minas Gerais, Brazil, identified the most frequent serovars of Leptospira interrogans, and examine the renal pathological changes associated with the disease. Samples of blood serum and kidney fragments from 100 bovine females were collected in cattle abattoir. In the serological investigation 48% of the cows were positive. The serovars for which there were more reactive animals were Wolffi (24%), Hardjo (21%) and Hebdomadis (18%). Among the positive samples, 14/48 showed antibody titers greater than 1:100, and 70.83% of the seropositive animals responded to more than one Leptospira interrogans serovar. Only one farm did not have seropositive cows and in nine farms studied, six (66.66%) presented seropositive animals to the Hebdomadis serovar. At the histopathological examination, the most frequent microscopic lesions in positive animals were hyalinization (81.25%), congestion (81.25%) and hydropic degeneration (70.83%). However, these histopathological alterations were also found in kidneys of animals negative to serology, such as hyalinization (80.77%), congestion (48.07%) and hydropic degeneration (55.77%) and these findings are unrelated to positivity. Histopathological examination of the kidneys is not indicated to replace the serological diagnosis of leptospirosis, and may be used only as a complementary examination. Despite the low frequency of seropositive animals in the Triângulo Mineiro region, the disease is present in a large number of farms. Noteworthy is the high frequency of serovar Hebdomadis and it can be considered an emerging serovar in the region. The evaluation of the frequency of this serovar in other regions becomes important, and once verified should result in the recommendation of the inclusion of this serovar in the leptospirosis control.

Population constituted of nine professionals working in the team for at least six months, interviewed in August / 2016. Data analysis followed content analysis, thematic modality. Nine professionals participated: six community health agents, one physician, one dentist and one oral health aide. The results that emerged from the interviews were grouped by content affinity, in four thematic units, of which two referred to difficulties (restrictive factors) and two, to facilities (driving factors) for teamwork. Restrictive factors for teamwork were included in thematic units: Inadequate organization and resources and weakened interpersonal relationships. It has been shown that inadequate organization / resources and fragile interpersonal relationships restrict and limit teamwork in the Family Health Strategy. The driving factors for teamwork were gathered in thematic units: In-service training and interpersonal relationships based on appropriate collaboration and communication. It was verified that in-service training and interpersonal relationship, based on collaboration, mutual aid and communication, impelled the said teamwork. Both the restrictive and the driving factors for teamwork are linked to the conditions for carrying out the work and the relationship between team agents. The evidence found in this research can lead to advances in organizational behavior, with emphasis on management practices aimed at ensuring and supporting the effective development of the teamwork modality

Diabetes mellitus treatment is complex and involves several activities. Its goal is to control the disease and prevent complications. The success of this treatment includes adherence to self-care. This study aimed at identifying factors related to self-care activities adherence in community older adults with diabetes. Cross-sectional, observational and analytical study with a quantitative approach to data, conducted with 140 older people. We used the following instruments: Mini-Mental State Examination for cognitive assessment, socio-demographic and clinical characterization instrument, Brazilian Functional and Multidimensional Assessment Questionnaire to verify the self-reported morbidities, Abbreviated Geriatric Depression Scale to investigate the presence of depressive symptoms and Diabetes Self-Care Activities Questionnaire to assess activities adherence related to self-management of people with diabetes. The results of this study indicated that self-care activities with higher adherence were: “taking the indicated number of diabetes pills” (6.6 ± 1.2), “taking insulin injections as recommended” (6.2 ± 2.0), “drying the spaces between the toes after wash them” (4.6 ± 3.2) and “following a healthy diet” (4.5 ± 2.7). The self-care activities with smallest adherence were: “performing specific physical activities (walking, swimming, etc.)” (0.9 ± 1.9), “performing physical activities for at least 30 minutes” (1.2 ± 2.2), “evaluation of blood sugar as times as recommended” (1.2 ± 2.3), “sweets intake” (1.3 ± 1.7) and “evaluation of blood sugar” (1.4 ± 2.3). Regarding smoking, 88.6% were not smokers. Factors related to self-care measures were: gender, indicating greater adherence of women, education level, and number of morbidities, suggesting that adherence to the feet care domain is directly proportional to education and number of morbidities. However, this same domain was inversely proportional to depression, indicating that there was greater adherence in those people without depressive symptoms. The factors associated with the adherence to self-care activities observed in this research contributed to the planning of strategies to prevent diabetes mellitus complications and promote improvements in the life and health of the older adults in the community.

To evaluate the biomass flow of two cultivars of Cynodon (Tifton 85 grass and vaquero grass) fertilized with increasing levels of nitrogen (N) (control – without nitrogen; 200; 400 and 600 mg dm-3) under greenhouse conditions, this study was carried out, in a completely randomized design, with factorial arrangement. Forages were examined during three regrowth cycles, with results presented as mean values of the cycles. In the analysis of the effect of nitrogen fertilization, the Tifton 85 grass showed an increasing response to nitrogen levels for the leaf elongation rate (LER). The vaquero grass had a quadractic response for the LER with increasing levels of N. As for the stem elongation rate, there was an increasing linear response in both grasses according to increasing levels of N. The leaf senescence rate (LSR) of the Tifton 85 grass has been enhanced by nitrogen fertilization. The vaquero grass revealed a quadractic response for this variable LSR with nitrogen fertilization, with a minimum value of 0.96 cm tiller-1 day-1 with nitrogen level of 42.5 mg dm-3. The phyllochron and the total number of leaves of both grasses have been influenced by nitrogen fertilization, with downward and upward linear responses, respectively, with increasing levels of nitrogen. For the final mean leaf length (MLL) of both forages, we verified an increasing response with increasing levels of nitrogen. Tifton 85 grass and vaquero grass presented similar LER in the absence of nitrogen, but higher values were observed for the fertilized Tifton 85 grass. The fertilization using nitrogen leads to positive responses of the biomass flow of Tifton 85 grass and vaquero grass under the conditions of the present study.

A produção de mudas é um ponto crítico do sistema de produção de hortaliças. Devido a informações sobre o consumo de água pelas mudas, o planejamento da irrigação se torna ineficiente, fato que provoca perdas na qualidade das mudas. O objetivo do experimento foi testar o uso de hidrogel no substrato e determinar o manejo de irrigação adequado através de ferramentas de automatização do sistema de irrigação. O experimento foi conduzido em ambiente protegido na Universidade Federal de Viçosa. Foram produzidas mudas de tomate (Solanum lycopersicom) em bandejas de polietileno, preenchidas com substrato com e sem a presença de hidrogel. As mudas foram irrigadas com sistema de microaspersão, acionado a partir de um sistema automatizado. Os tratamentos de manejo de irrigação foram através da evapotranspiração da cultura (ETc), timer, 0.50 ETo e 1,00 ETo. Foram avaliados componentes de qualidade das mudas como altura, comprimento de raiz, diâmetro de colo, massa seca de raiz e parte aérea. O uso do hidrogel foi um diferencial para produção de mudas de tomate mais precoces, com maior altura final, maior diâmetro de colo, maior acúmulo de massa seca de parte aérea, maior área de projeção da copa e maior a taxa de crescimento relativo de parte aérea. Na presença do hidrogel o manejo 0.50 ETo favoreceu maiores plantas, com colo mais fino e menor massa seca de parte aérea.

Published: February 2020

El estudio tuvo como objetivo identificar el nivel de satisfacción con la vida en un grupo de migrantes guatemaltecos retornados desde los EE. UU. a Guatemala. Participaron 110 personas (hombres 86,50 % y 13,50 % mujeres). Se utilizó una escala de datos sociodemográficos y la escala de satisfacción con la vida (Diener et al., 1985). Los resultados indican que 74,80 % de los participantes manifiestan estar satisfechos con su vida a pesar de haber sido deportados desde los EE. UU. Se realizó una serie de correlaciones entre las variables sociodemográficas y el nivel de satisfacción con la vida y se evidenció una correlación negativa entre satisfacción con la vida y el número de intentos por llegar a Estados Unidos (r=-0.318; p< 0.01).

Published: February 2020

Goal: This study developed a structured decision model capable of solving the storage location assignment problem (SLAP) in a picker-to-parts system, using multiples key performance indicators (KPIs).

Design / Methodology / Approach: A hybrid approach was developed. For that, a Multi-Objective Genetic Algorithm (MOGA) was used considering three fitness functions, but more functions may be considered. Through MOGA it was possible to verify a high number of solutions and reduce it into a Pareto frontier. After that, a Multiple-Criteria Decision-Making (MCDM) approach was used to choose the best solution.

Results: This model was able to find viable solutions considering multiples objectives, warehouse restrictions and decision makers’ preferences, and the required processing time for the simulated cases was insignificant.

Limitations of the investigation: One limitation of this work was the consideration of known and predictable data.

Practical implications: The proposed model was developed with the purpose of assisting companies that face this type of problem, providing a solution for SLAP requiring the minimum information and operational actions.

Originality / Value: SLAP is a NP (Non-Deterministic Polynomial time) complex problem and, after the MOGA, the number of solution can be still high for the final decision making by the engineering manager (decision maker - DM). Thus, the MOGA–MCDM hybrid approach developed was able incorporate the DM' preferences into a compensatory view, vetoing alternatives that were worse in any of the KPIs, to recommend a final solution.

Paranın geçmişi, takas ekonomisi, madeni para, kâğıt para, itibari para ve dijital para şeklinde tarihi bir seyir izlemiştir. Küresel likidite krizlerinin ardından artık doların rezerv para olma tekeline karşı tartışmalara başlanmış ve bu tartışmalar paralelinde 2009 yılından sonra Blok-zincir teknolojisinin yaygınlaşması Bitcoin, Etherium, Ripple ve Litcoin gibi kripto paraların finansal piyasalarda görülmesine ve yaygınlık kazanmasına yol açmıştır. Kripto paralara ilişkin önerilen alternatifler arasında petrole, yerel para birimlerine veya altına dayalı dijital para ihraçlarının iyi bir çözüm olabileceği ifade edilmektedir.

Küresel piyasalarda rezerv para birimi ve alternatif ödeme sistemleri arayışı devam ederken söz konusu gelişmeler İslami piyasalar açısından değerlendirilerek bu alanda bir çözüme ihtiyaç duyulduğu gözlenmiştir. Bu çalışmada tespit edilen ihtiyaca yönelik olarak mevcut önerilerin eksik yanlarını tamamlayarak, piyasalara güven telkin eden ve alternatif bir ödeme sistemi olarak geliştirilen “İslami Coin” (IsCoin) olarak isimlendirdiğimiz helal kripto para sisteminin nasıl tasarlanması gerektiği ele alınmaktadır.
