Clinical Relevance
Pigments in tooth structures affect the diffusion of H2O2 through enamel and dentin. The bleaching methodology can be impacted.

SUMMARY
Objective: The aim of this study was to evaluate the influence of the presence of pigments in tooth structures on the trans-enamel and trans-dentin diffusion of hydrogen peroxide (H2O2) and its cytotoxicity after carrying out an in-office bleaching therapy.
Methods and Materials: A bleaching gel with 35% H2O2 was applied for 45 minutes (three times for 15 minutes) on enamel and dentin discs (n=6), either previously submitted to the intrinsic pigmentation protocol with a concentrated solution of black tea, or not, defining the following groups: G1, unbleached untreated discs (control 1); G2, unbleached pigmented discs (control 2); G3, bleached untreated discs; G4, bleached pigmented discs. The discs were adapted to artificial pulp chambers, which were placed in wells of 24-well plates containing 1 mL culture medium (Dulbecco’s modified Eagle’s medium [DMEM]). After applying the bleaching gel on enamel, the extracts (DMEM + components of bleaching gel that diffused through the discs) were collected and then applied on the cultured MDPC-23 odontoblast-like cells. Cell viability (methyl tetrazolium assay and Live & Dead, Calcein AM, and ethidium homodimer-1 [EthD-1] probes), the amount of H2O2 that diffused through enamel and dentin (leuco-crystal violet product), and the H2O2-mediated oxidative cell stress (SOx) and components of degradation were assessed (analysis of variance/Tukey; α=0.05).
Results: There was no significant difference between the groups G1 and G2 for all the parameters tested (p&gt;0.05). Reduction in the trans-enamel and trans-dentin diffusion of H2O2 occurred for G4 in comparison with G3. Significantly lower cell viability associated with greater oxidative stress was observed for G3 (p&lt;0.05). Therefore, in-office tooth bleaching therapy performed in pigmented samples caused lower cytotoxic effects compared with untreated samples submitted to the same esthetic procedure (p&lt;0.05).
Conclusion: According to the methodology used in this investigation, the authors concluded that the presence of pigments in hard tooth structures decreases the trans-enamel and trans-dentin diffusion of H2O2 and the toxicity to pulp cells of an in-office bleaching gel with 35% H2O2.

A theory of global economic growth in the very long-run: is a grand innovation slowdown inevitable?
Authors: Gomulka Stanislaw 
Published: June 2020

Abstract
The paper shows how the original semi endogenous and balanced growth model of Phelps (1966), and my extended version of it (Gomulka, 1990), could be useful in explaining the key ‘stylized facts’ of global long-term growth so far, and in predicting its dynamics in the future. During the last two centuries the sector of R&D and education, producing qualitative changes, has been expanding in the world’s most developed countries much faster than the sector producing conventional goods. The extended model is used to explore and evaluate. the consequences for the global long-term growth of the end of this unbalanced growth, of the completion of the catching up by most of the world’s less developed countries, and of the expected eventual stabilization of the size of the world population. The theory yields a thesis, new in the literature, that the rate of global per capita GDP growth will eventually return to the historically standard very low level, thus implying that the world’s technological revolution is going to be an innovation super-fluctuation.
Liquidity and solvency of a company and the rate of return – an analysis of the Warsaw Stock Exchange
Authors: Zalewska Justyna , Nehrebecka Natalia 
Published: June 2020

Abstract
The purpose of the article is to analyse the impact of various financial ratios used to evaluate a company’s liquidity and solvency on the rates of return on the shares of companies listed on the Warsaw Stock Exchange. In the context of developing countries, the relationship between liquidity and solvency on the one hand and the return on equity on the other is still not clear. Poland is the most economically developed country in Central and Eastern Europe. A thorough analysis is necessary to take appropriate action and introduce adequate regulations in the country, as well as to create the foundation for researching other economies in this region. In addition, this article includes new estimators that have not yet been taken into account but that may affect the rates of return, which will contribute to the literature on the subject and to the development of knowledge on the volatility of returns on shares. In the study, we have calculated the time-varying beta coefficients of the capital asset pricing model (CAPM) model and analysed portfolios based on three liquidity ratios and four solvency ratios, which were computed using the CAPM, Fama–French and Carhart models. The empirical study described in the article focuses on companies listed on the Warsaw Stock Exchange in the period from 1 January 1999 to 30 June 2013. Regressions were estimated by the least-squares method and by quantile regression. Based on the results, it was found that listed companies at risk of bankruptcy are able to meet their short-term liabilities. Liquidity and solvency measured by financial ratios significantly affect the sensitivity of the rate of return on shares to the risk factors expressed in the CAPM, Fama––French and Carhart models.
The Media Welfare State: Why such a concept, what is it used for, does it have a future?
Authors: Enli Gunn , Syvertsen Trine 
Published: June 2020

Abstract
In 2014, Syvertsen, Enli, Mjøs, and Moe authored The Media Welfare State: Nordic Media in a Digital Era to explore the specificities of Nordic media and the analogy between welfare state and media structures. In this short article, we point to how selected works challenge or extend the notions of a media welfare state beyond the original analysis. We begin by placing the work in a tradition of comparative and typology-generating scholarship and point to parallel works emerging at the same time. We then highlight others’ contributions in order to identify tendencies in Nordic media and research. In conclusion, we use examples from current research to argue that changes in the media system may be studied from both the angle of changing media policies and that of changing welfare states.
Under the Influence of Politics: Mediatisation and politico-administrative systems in Scandinavia
Authors: Figenschou Tine Ustad , Fredriksson Magnus , Pallas Josef , Salomonsen Heidi Houlberg 
Published: June 2020

Abstract
This conceptual article extends three ongoing scholarly debates on the mediatisation of politics – the risk of media centrism, the tendency to see mediatisation as a linear process, and the preoccupation with elected officials. We argue for the need to identify, foreground, and systematise non-media dimensions of mediatisation processes. We also argue that actors encounter mediatisation as a set of dynamic ideas rather than a fixed logic. With a focus on government agencies and a comparison of the politico-administrative systems in Denmark, Norway, and Sweden, this article gives certain attention to politicisation, autonomy, and accountability and suggests that the degree of freedom granted to agencies in Denmark and Norway is relatively limited compared with agencies in Sweden. Consequently, we present two propositions: 1) agencies in Denmark and Norway are less inclined to mediatise, whereas 2) Swedish government agencies will more likely mediatise and show conformity with widely accepted norms regarding media.
The Community Pharmacy Technician’s Role in the Changing Pharmacy Practice Space
Authors: Taylor Brooke , Mehta Bella 
Published: June 2020

Purpose: The practice of pharmacy and role of pharmacists has evolved over the decades but markedly since the introduction of the Affordable Care Act (ACA) in 2010. The ACA allowed patients to have increased access to community pharmacy services, such as medication therapy management, leading to an increase in the clinical services provided by pharmacists. This expansion of pharmacist’s roles has led to pharmacists to feel an increase in workload which negatively impacts the time spent with patients. One way for this shift to occur without continuing to increase the pharmacist’s workload is by using technicians as pharmacist extenders to take on more technical tasks.
Summary: The role of pharmacy technicians has been slow to expand from fear of public safety due to the lack of required education and training. Today, state requirements to practice as a pharmacy technician have become stricter with state requiring licensing, registration or certification. This increase in requirements as led to the expansion of pharmacy technician duties. Studies show that pharmacy technicians are able to perform technician accuracy checking, provide immunization and perform Clinical Laboratory Improvement Amendments (CLIA)-waived screenings. In addition to these duties, pharmacy technicians are being utilized in more novel ways such as collecting medication information in primary care and telepharmacy settings.
Conclusion: In order for pharmacy to continue to grow as a profession, pharmacists need to use pharmacy technicians as extenders. As pharmacy technicians begin to take on more of the technical duties, pharmacists are able to increase the time spent with patients.

Experimental study on thermal, rheological and filtration control characteristics of drilling fluids: effect of nanoadditives
Authors: Veisi Erfan , Hajipour Mastaneh , Biniaz Delijani Ebrahim 
Published: June 2020

Cooling the drill bit is one of the major functions of drilling fluids, especially in high temperature deep drilling operations. Designing stable drilling fluids with proper thermal properties is a great challenge. Identifying appropriate additives for the drilling fluid can mitigate drill-bit erosion or deformation caused by induced thermal stress. The unique advantages of nanoparticles may enhance thermal characteristics of drilling fluids. The impacts of nanoparticles on the specific heat capacity, thermal conductivity, rheological, and filtration control characteristics of water‐based drilling fluids were experimentally investigated and compared in this study. Al2O3, CuO, and Cu nanoparticles were used to prepare the water-based drilling nanofluid samples with various concentrations, using the two-step method. Transmission Electron Microscopy (TEM) and X-Ray Diffraction (XRD) were utilized to study the nanoparticle samples. The nanofluids stability and particle size distribution were, furthermore, examined using Dynamic Light Scattering (DLS). The experimental results indicated that thermal and rheological characteristics are enhanced in the presence of nanoparticles. The best enhancement in drilling fluid heat capacity and thermal conductivity was obtained as 15.6% and 12%, respectively by adding 0.9 wt% Cu nanoparticles. Furthermore, significant improvement was observed in the rheological characteristics such as the apparent and plastic viscosities, yield point, and gel strength of the drilling nanofluids compared to the base drilling fluid. Addition of nanoparticles resulted in reduced fluid loss and formation damage. The permeability of filter cakes decreased with increasing the nanoparticles concentration, but no significant effect in filter cake thickness was observed. The results reveal that the application of nanoparticles may reduce drill-bit replacement costs by improving the thermal and drilling fluid rheological characteristics and decrease the formation damage due to mud filtrate invasion.

Authors: Bastos Sarita Sousa 
Published: June 2020

INTRODUÇÃO: A prescrição é uma etapa importante da consulta pediátrica e depende do arsenal farmacoterapêutico disponível. Na prática, as crianças são habitualmente submetidas à terapia com medicamentos estudados apenas em adultos, configurando assim o uso off-label. OBJETIVOS: Analisar a frequência de prescrições de medicamentos off label em enfermaria pediátrica de um hospital –escola referência no Piauí. METODOLOGIA: Estudo observacional e transversal realizado na enfermaria de pediatria clínica de um hospital infantil público referência em Teresina-Piauí no período de junho a julho de 2017. A classificação quanto aos critérios de aprovação da Agência de Vigilância Sanitária (Anvisa) foi baseada em seu bulário eletrônico e no Dicionário de Especialidades Farmacêuticas (2009). RESULTADOS: Foram analisadas 1.697 prescrições referentes a 93 pacientes. O gênero feminino (51,6%) e a faixa etária de lactentes (30,1%) foram os mais frequentes. Dos 13.276 itens medicamentosos prescritos, 13,7% foram de uso off label. Destes, 65,2% eram manufaturados - adaptados de sólido para líquido no hospital através da equipe de enfermagem – e 16,6% não estavam prescritos na dose correta para faixa etária ou peso. A dipirona foi o fármaco mais prescrito de forma off label (12,7%), seguido pelo montelucaste (11,3%) e omeprazol (10,3%). CONCLUSÃO: Os resultados do presente trabalho confirmam a baixa prevalência do uso off-label em relação a outros estudos, porém com altas taxas de medicamentos manufaturados.
