Authors: De-Salas-Nestares Isabel , Martínez-Sáez José , Roca-Hueso Víctor
Published: July 2019

Este trabajo parte de una premisa: el advenimiento y generalización de la tecnología digital ha introducido profundos cambios en la manera en que nos comunicamos entre nosotros y en la forma en que la publicidad logra su eficacia. Nuestro trabajo parte de las siguientes hipótesis: en la era digital las marcas precisan de un cambio profundo en sus claves persuasivas para lograr sus metas (H1). Y este cambio provoca como necesidad la generación de nuevos perfiles profesionales (H2). Estos nuevos perfiles afectan a las estructuras de las agencias(H3). Para su validación o refutación el equipo investigador pergeña un constructo metodológico que le permita abordar el fenómeno desde una perspectiva holística atendiendo tanto a los últimos desarrollos en el marco teórico como a la mirada de profesionales reputados. Para ello se han realizado entrevistas en profundidad a planners y directores creativos, focus group y un Delphi al final para confirmar los resultados. Estos se ha estructurado en 6 ejes que han dado como aportación principal la necesidad de que los publicitarios dominen el lenguaje de los nuevos medios, el requisito de huir de los estereotipos y adquirir una relevancia real para las personas y la identificación de cambios en los roles profesionales que gestionan la publicidad.
Autorregulação publicitária em Portugal: os interesses da indústria e dos consumidores em convergência?
Authors: Duarte-Melo Ana
Published: July 2019

A autorregulação publicitária está no centro das discussões jurídicas, económicas, sociais e éticas que confrontam a comunicação comercial e a defesa dos direitos do consumidor. Os seus defensores consideram ser este o sistema regulatório mais eficiente para a publicidade, pois envolve o comprometimento voluntário com um código de conduta específico, não tendo, portanto, que enfrentar os desafios de conformidade de leis obrigatórias e indesejadas. Os seus detratores denunciam esses esforços como forma de manter o controlo da mensagem publicitária e evitar legislações mais duras. Neste artigo faremos o mapeamento da atividade de autorregulação publicitária em Portugal, acompanhando instituições, iniciativas e orientações ao longo dos últimos trinta anos, estabelecendo uma linha do tempo desde a fundação da primeira organização de autorregulação do sector no país. Analisaremos de que forma os direitos dos consumidores se encontram protegidos, quer nos princípios e valores enunciados, quer nos mecanismos de autorregulação disponibilizados. Discutiremos ainda as potencialidades e desafios da autorregulação face às novas formas de publicidade ou como incorpora e responde às preocupações contemporâneas da sociedade civil, assumindo-se como plataforma de interação dos interesses da indústria, dos media e dos consumidores. Concluímos sobre a evidência exposta a partir da autorregulação da relevância do papel da ética e da responsabilidade social da atividade publicitária.

Published: July 2019

An efficient synthesis of novel 2,3,4-trisubstituted 1,5-benzothiazepines (4a-e) incorporating the sulfonyl group is described. Compound (4a-e) was synthesized by the reaction of 3-(1,4-dioxane-6-sulfonyl)-2,4-dimethyl/4-methyl-2-phenyl/2,4-diphenyl/2-ethoxy-4-methyl/2,4-diethoxy propane-1,3-dione (3ae) with 2-aminobenzenethiol with ZnOnanoparticles/pyridine. Formation of compound (3a-e) was achieved by the reaction of 1,4-dioxane-6-sulfonyl chloride (1) with 2,4-dimethyl/4-methyl-2-phenyl/2,4-diphenyl/2-ethoxy-4-methyl/2,4-diethoxy propane-1,3-dione (2a-e). The benzothiazepines (4a-e) obtained were purified by column chromatography (benzene: CHCl3, 40:60, 30:70, 20:80, 10:90) and crystallized from methanol. The purity of the compounds was checked by TLC using (CHCl3: CH3OH, 9:1) as the mobile phase. The structure of the compounds has been established by elemental, IR, 1H NMR, 13C NMR and Mass spectral analyses. Frontier molecular orbitals of the title compounds have been studied in the ground state speculatively. The reactivity of a molecule using diverse descriptors such as softness, electrophilicity, electronegativity, HOMO-LUMO energy gap is calculated additionally discussed.

Published: July 2019

Formulation of poorly water-soluble drugs for oral drug delivery has always been a difficult task for formulation scientists. Lurasidone hydrochloride is one such agent which is used to control bipolar depre-ssion. The objective of this study was to formulate and optimize lurasi-done nanosuspension, further formulating optimized nanosuspensions as fast disintegrating tablets for improved patient compliance. In the present study, lurasidone nanosuspension was prepared by nanomilling technique. Optimized nanosuspension has mean particle diameter of 248.9 nm, polydispersity index of 0.127 and zeta potential of 18.1 mV. The lyophilized optimized nanocrystals, optimize nanosuspension as granulating fluid and as top spraying dispersion for granulation in fluid bed granulator being used to formulate fast disintegrating tablets with suitable super disintegrant. Croscarmellose sodium was found to be best superdisintegrant compared to sodium starch glycolate and crospovidone, as its acts by both mechanism swelling and wicking. Its swells 4-8 folds in less than 10 s. Many folds increase in the rate of drug release observed compare to micronized lurasidone and marketed product. There was no change in crystalline nature after nanomilling as characterized by XRD and FTIR, and it was found to be chemically stable with high drug content. The developed fast disintegrating tablets would be an alternative better formulation than its conventional formulation to address its bioavailability issue and for improved patient compliance. However, this should be further confirmed by appropriate in vivo studies.
ABOUT THE POSSIBILITY COATING OF PAPER IN THE PROCESS OF AERODYNAMIC FORMING
Authors: Malinovskaya Galina Kirillovna , Litvinova Lidiya Vladimirovna
Published: July 2019

Forming a paper web by an aerodynamic method is carried out by deposition of fibers and paper components from a stream of air on a forming wire. Necessary properties of written and printed types of paper are ensured by the introduction of mineral fillers into the composition of the paper. The method used allows you to enter the filler both in the process of forming a fibrous layer, and as a coating on one side of a sheet of paper. Mineral fillers improve the printing properties of the paper, but reduce the strength of the paper.

The analysis of the negative effect of the filler on the tensile strength of paper was carried out. The theoretical understanding of the mechanism of retention of filler in the structure of the paper web are given. The dependences of the degree of retention of the filler on the specific weight of the fibrous layer and the diameter of pores in the paper web are considered. The main factor in the retention of the filler in the process of surface coating is the ratio of the average particle diameter of the filler and the diameter of the through interfiber pores. These data can be used in experimental and practical work with new types of fillers, with natural and synthetic fibers.

With the method of aerodynamic molding, paper samples were obtained when the filler was applied both to the structure and to the surface of the paper web. To increase the adhesion strength, the surface of the filler particles is modified with a solution of Na-carboxymethyl-cellulose. A comparative assessment of coated paper samples from various wood species by optical indicators, values of roughness and air permeability values of paper is given. A method for introducing a filler into the paper structure during aero molding is proposed. The developed method of paper coating in the process of aerodynamic formation can be applied in the manufacture of printing paper and containerboard.

Published: July 2019

It is known that various types of willow contain a rich polyphenolic complex of biologically active substances (BAS) (phenolic glycosides, flavonoids, tannins and phenolic acids). The same substances are found in the Salix triandra. In view of the fact that oral administration of dried medicinal plant material is now expedient, it is also of interest to study other BASs contained in the plant, in particular, the pigments. Using as an example a willow bine, it is shown that when determining the chlorophyll content in dried plant raw materials, it is necessary to take into account the fact of the pheophytin formation. Using the TLC method, pigments of the willow are found in leaves (bines): β-carotene, chlorophyll a and b, pheophytin and xanthophyll. When using the spectrophotometric method, it is found that the content of chlorophylls in a the willow bines varies from 0.032 to 0.18% and depends on the place of growth and seasonal factors (amount of sunlight, temperature and ecology of the environment). These values are almost 2 times different from the content of chlorophylls in leaves, but their amount can contribute to the pharmacological effect by oral intake of dried and powdered willow bines. It is found that when extracting the raw material with hexane, the content of the sum of carotenoids in terms of β-carotene is found to be not more than 2.5 mg /% in both leaves and bines of Salix triandra.

Plants of Helichrysum genus belong to Asteraceae family and abound with species. The’re two species of plants of Helichrysum genus in the Astrakhan region – Helichrysum arenarium Moench and Hеlichrisum nogaicum Zvelev that was discovered later and isn’t studied well enough yet. Helichrysum arenarium is a well-known medical plant widely used in both academic and traditional medicine and included into the State Pharmacopoeia. Inflorescences of Helichrysum arenarium produce cholagogic, hemostatic, detoxicating, laxative, anti-inflammatory and diuretic effects, which is due to content of flavonoids, terpenoids and other components. This works shows results of studies of chemical composition of extracted essential oils of Hеlichrisum nogaicum and Helichrysum arenarium growing in the Astrakhan Region. Samples of essential oils of plants under studies have been obtained by steam distillation. Optimal steam distillation process duration has been determined by experiment taking studies of dynamics of essential oil yield change through time as a ground. Quantitative analysis of main components of Helichrysum arenarium and Hеlichrisum nogaicum essential oils has been carried out by gas-liquid chromatography. It has been identified that Helichrysum arenarium essential oil contains 21 substances. Its main components are camphor (14.59%) and carboxylic acids (37.02%), and 1,8-cineole (5.97%). The main components of the oil Helichrisum nogaicum are camphor (38.33%), borneol (14.21%), cineol-1.8 (11.37%) and terpene-4-ol (5.18%), sesquiterpene compounds (6.28%), and the content of carboxylic acids is insignificant and amounts to 6.58%.

Published: July 2019

The ability of a material not to change its properties when heated is an important characteristic of nonwoven and fibrous polymeric materials (VPM). The interaction of binder components, flax cellulose and non-cellulose impurities will largely determine their properties, including resistance to thermal oxidation. In this paper were used as objects of research cotton linen, samples of purified cellulose, extracted lignin, cotton fiber based on cotton linen, impregnated with polymer binders.

Enzyme-modified flax is obtained by effective fibration due to the selective hydrolysis of pectins and hemicelluloses, while structure-forming lignin has been preserved. The formation of VPM was performed by impregnation of undirected fibers located in the canvas with a binder based on 50% polyvinyl acetate emulsion and cyclic PA-6 oligomers (polymerization degree 6–11).

Fiber-polymer materials based on cottonin- flax with various types of binders were obtained, their thermal properties were studied on the Synchronous Thermal Analyzer – STA 449 F3 Jupiter®. Resistance to burning was evaluated according to standard 12.4.184. The effect of the introduction of natural aluminosilicates on the thermal properties of fibrous-polymeric materials has been studied.It was revealed that fibrous-polymeric materials with the inclusion aluminosilicate (from Malostupino) have low burnability.

The aim of the work is research of straw pyrolysis in various modes, the determination of process thermal effects and estimation of straw thermal processing possibility in the autothermal mode.

Physical experiment and differential thermal analysis were used as research methods. Thermotechnical characteristics of raw materials are determined by ISO 1171:2010, GOST R 55660-2013 and a bomb calorimeter; thermal and physical characteristic are determined by the analyzer of thermal diffusivity Discovery Laser Flash DLF-1200.

In result of the work is established that thermal effects occur in the straw after heating to 200 °C. The first shows of exothermic reactions are observed when the reactor is heated to 303 °C – in this case the temperature of the straw reaches 308.8 °C. By differential thermal analysis is established that the temperature range of heat input was set from 235 to 575 °C and value of the thermal effect in this range was set 1475 kJ/kg. For this range, the heat costs for the organization of pyrolysis in the autothermal mode and the total thermal effect of the process are calculated. The calculation results showed that the maximum thermal effect (398.9 kJ/kg) can be obtained at a pyrolysis temperature of 460 °C. For these conditions, the influence of the initial straw moisture content on the autothermality of pyrolysis process was evaluated and it was established that process can be organized due to its own thermal effects when the raw material moisture is less than 30.5%.
INFRARED SPECTROSCOPY OF WOOD OF PINE, BIRCH AND OAK, MODIFIED WITH MONOETHANOLA-MINE(N→B)THREEHYDROXYBORATE
Authors: Kotlyarova Irina Aleksandrovna
Published: July 2019

The article presents the results of IR-spectroscopic study of wood of pine, birch and oak, modified with 50% aqueous solution of monoethanolamine(N→B)threehydroxyborate. IR spectra of the samples of birch and oak, modified by monoethanolamine(N→B)threehydroxyborate havebeen obtained for the first time. It was found that the modifier chemically interacts at room temperature with the reactive groups of the tree species under study; the chemical bonds being formed are hydrolytically stable. It is revealed that the change in the supramolecular structure of the modified wood is associated with a change in the system of hydrogen bonds. It is shown that the in the case of modifyingwith monoethanolamine(N→B)threehydroxyborate, there is no destruction of the aromatic rings of lignin, and the main chains of the macromolecules of cellulose, i.e. modifying is in "soft" conditions. It was found that the modifier interacts with the primary hydroxyl groups of cellulose and carboxyl groups of lignin in the modification of pine wood; when modifying, the wood of birch and oak monoethanolamine(N→B)threehydroxyborate mainly interacts with the carboxyl groups of lignin. The density of the grafting modifier depends on the availability of reactive groups of wood composite, and it decreases with increasing the density of wood. Taking into account that surface grafted compounds determine many properties of wood (specific surface area, water absorption, swelling, bio- and fire-resistance), different grafting density and surface distribution of grafted molecules of modifiers on the surface of wood samples under study will lead to differences in the listed properties of the modified wood materials.

Cultivation of plant raw materials in artificial conditions will inevitably lead to a change in the qualitative and quantitative composition of secondary metabolites in comparison with the composition of plants obtained in soil conditions. The study of the metabolic profile of such plants is very important on the one hand for our understanding of temporal (ontogenetic) and spatial changes in the metabolome of plants, on the other hand in the applied plan to obtain an alternative quality medicinal plant raw materials. In this regard, the aim of this study was to study the content of phenolic compounds in biotechnological raw materials Iris sibirica Grade Стерх in comparison with intact plants.

As objects of study used plants propagated mikrokanale (regenerants), which were further grown under conditions of hydroponics (hydroponic). Intact plants were harvested in the field at the age of six years. As a result of research in raw materials Iris sibirica Grade Стерх, grown under different conditions, were found following a group of biologically active compound (БАС), corresponding to the genus Iris L.: fenilpropionovoy acid (Komarova and ferulic acid and their derivatives), flavonoids (glycosides of apigenin, apigenin-7-O-glycoside), isoflavones, and phenolic acids (vanillic acid), neytralizuya flavonoids-glycosides (glycosides of kaempferol and apigenin), stilbene. The qualitative composition of biologically active compounds of Iris sibirica Стерх depended on the growing conditions, while the biotechnological raw materials (hydroponic plants) are the closest to intact plants in terms of the content of biologically active compounds.  This allows us to consider the biotechnology of obtaining the raw material Iris sibirica L. based on hydroponic cultivation coupled with the micropropagation in an alternative way.

This special issue of Monthly Review is meant both to celebrate the fiftieth anniversary of Harry Magdoff's The Age of Imperialism: The Economics of U.S. Foreign Policy, which was devoted to the analysis of imperialism at the height of U.S. hegemony, and to carry this analysis forward to address the present era of late imperialism in the twenty-first century. In bringing together work on the political economy of imperialism in the current era of globalized production, we seek to transcend the now fashionable view within the Western academic left that the concept of imperialism is obsolete. The imperialist world system stands not only for capitalism at its most concrete historical level, but also for the entire dynamic structure of power constituting accumulation on a world scale, which can only be understood in terms of a developing global rift between center and periphery, global North and global South. Failure to attend to this fissure would be fatal for humanity.
The Preemptive Counterrevolution and the Rise of the Far Right in Brazil
Authors: Antunes Ricardo
Published: July 2019

During the 2018 Brazilian presidential elections, almost thirty years after the first democratic elections since the military dictatorship, Jair Bolsonaro took on the role of supposed underdog and, in the face of the collapse of the other center and right-wing bourgeois candidates, became the only one capable of countering the risk of the victory of the Workers' Party. Bolsonaro, or the captain, as he is frequently called by his acolytes, is a sort of Donald Trump of the periphery—a second-rate Trump. Though he appears to be the most radical critic of the system, he is, in fact, the very image of the status quo, in all its brutality and rawness.
A Note on the Communist Manifesto
Authors: Magdoff Harry
Published: July 2019

This reprise of Harry Magdoff's 1969 "A Note on the Communist Manifesto" remains as relevant as ever—perhaps even more so. While capitalism by its very nature lives by accumulation and geographic expansion, it does so in a most unequal fashion. Even though nothing in economics follows strict mathematical rules, there are notable tendencies produced by the inner springs of capitalism. An outstanding example of such a tendency is found in the distinct and marked widening of the gap between a handful of rich nations and the rest of the world. The accelerating globalization of our times demonstrates this polarization in no uncertain terms.

The study investigated the predictive role of pay satisfaction and organisational politics on quality of work life. Herzberg’s Two-Factor Theory was used as a theoretical framework in this study. Cross sectional survey research design was adopted. Data were collected from 429 respondents consisting of (Females = 231(53.8%), Males = 198(46.2%) (Mean age = 39.14, S.D = 12.07) via a simple random and convenience sampling techniques. Work-Related Quality of life scale (WRQLS), Pay Satisfaction Questionnaire (PSQ) and Perceived Organisational Politics Scale (POPS) were used as instrument for data collection. Data collected were analysed using Pearson moment correlation (PPMC) and Multiple Regression analysis. There was significant positive relationship between pay satisfaction and quality of work life. Positive relationship was found between organisational politics and the quality of work life. Finally, pay satisfaction and organisational politics jointly predict quality of work life. These findings have implications for putting up psychological interventions aim at improving the quality of work life of government employees.

Authors: Noor M.A. , Noor K.I. , Iftikhar S.
Published: July 2019

In this paper, we show that harmonic convex functions $f$ is strongly $(p, h)$-harmonic convex functions if and only if it can be decomposed as $g(x) = f(x) - c (\frac{1}{x^p})^2,$ where $g(x)$ is $(p, h)$-harmonic convex function. We obtain some new estimates  class of strongly $(p, h)$-harmonic convex functions involving hypergeometric and beta functions. As applications of our results, several important special cases are discussed. We also introduce a new class of harmonic convex functions, which is called strongly $(p, h)$-harmonic $\log$-convex functions. Some new Hermite-Hadamard type inequalities for strongly $(p, h)$-harmonic $log$-convex functions are obtained. These results  can be viewed as important refinement and significant improvements of the new and previous known results. The ideas and techniques of this paper may stimulate further research.

Published: July 2019

In this paper, we study the existence of the solutions of a class of functional integral equations by using some fixed point results in cone $b$-metric spaces over Banach algebras. In order to obtain these results we introduced and proved some properties of generalized weak $\varphi$-contractions, in which the $\varphi$ are nonlinear weak comparison functions. The obtained results are generalizations of results of Van Dung N., Le Hang V. T., Huang H., Radenovic S. and  Deng G. Also, some suitable examples are given to illustrate obtained results.
Asymptotics of the entire functions with $\upsilon$-density of zeros along the logarithmic spirals
Authors: Zabolotskyj M.V. , Basiuk Yu.V.
Published: July 2019

Let $\upsilon$ be the growth function such that $r\upsilon'(r)/\upsilon (r) \to 0$ as $r \to +\infty$, $l_\varphi^c = \{z=te^{i(\varphi+c \ln t)}, 1 \leqslant t < +\infty\}$ be the logarithmic spiral, $f$ be the entire function of zero order. The asymptotics of $\ln f(re^{i(\theta +c \ln r)})$ along ordinary logarithmic spirals $l_\theta^c$ of the function $f$ with $\upsilon$-density of zeros along $l_\varphi^c$ outside the $C_0$-set is found. The inverse statement is true just in case zeros of $f$ are placed on the finite logarithmic spirals system $\Gamma_m = \bigcup_{j=0}^m l_{\theta_j}^c$.
On some of convergence domains of multidimensional S-fractions with independent variables
Authors: Dmytryshyn R.I.
Published: July 2019

The convergence of multidimensional S-fractions with independent variables is investigated using the multidimensional generalization of the classical Worpitzky's criterion of convergence, the criterion of convergence of the branched continued fractions with independent variables, whose partial quotients are of the form $\frac{q_{i(k)}^{i_k}q_{i(k-1)}^{i_k-1}(1-q_{i(k-1)})z_{i(k)}}{1}$, and the convergence continuation theorem to extend the convergence, already known for a small domain (open connected set), to a larger domain. It is shown that the union of the intersections of the parabolic and circular domains is the domain of convergence of the multidimensional S-fraction with independent variables, and that the union of parabolic domains is the domain of convergence of the branched continued fraction with independent variables, reciprocal to it.
Interconnection between Wick multiplication and integration on spaces of nonregular generalized functions in the Lévy white noise analysis
Authors: Kachanovsky N.A. , Kachanovska T.O.
Published: July 2019

We deal with spaces of nonregular generalized functions in the Lévy white noise analysis, which are constructed using Lytvynov's generalization of a chaotic representation property. Our aim is to describe a relationship between Wick multiplication and integration on these spaces. More exactly, we show that when employing the Wick multiplication, it is possible to take a time-independent multiplier out of the sign of an extended stochastic integral; establish an analog of this result for a Pettis integral (a weak integral); and prove a theorem about a representation of the extended stochastic integral via the Pettis integral from the Wick product of the original integrand by a Lévy white noise. As examples of an application of our results, we consider some stochastic equations with Wick type nonlinearities.

La observación: un medio para mejorar la práctica docente
Authors: Gonzaga Martínez Wilfredo
Published: July 2019

En el ámbito de la educación y en especial en la evaluación educativa, por lo general, se recurre a exámenes y a otros instrumentos que, si bien son valiosos, no logran captar una serie de aspectos del individuo en determinado momento del proceso y del quehacer en el aula, tales como actitudes, comportamiento y desarrollo; que son elementos importantes para emitir un juicio de valor con relación al aprendizaje del estudiante o al desempeño del docente.

Para contribuir a una mejor valoración, la observación cumple un papel importante, por cuanto viene a ser un medio que permite complementar la información obtenida por medio de instrumentos de medición como pruebas escritas, escalas de calificación, listas de cotejo y registros anecdóticos, entre otros. Sin embargo, esta clase de observación requiere sistematización porque no se refiere a una actitud contemplativa, más bien necesita la actuación del sujeto sobre el medio mediante una planificación y constatación del efecto de sus acciones (Cortés y Deza, 2002).

El arribo de los españoles y la subsiguiente colonización del archipiélago de las Filipinas durante la segunda mitad del siglo XVI dan inicio a los viajes entre la ciudad de Manila y el puerto de Acapulco en México. La apertura de esta ruta marítima inaugura una época en la que, por vez primera, el comercio mundial se globaliza a través de estructuradas redes de intercambio. Previamente, los portugueses habían establecido una vía de comercio entre Europa, la India y China. Pero, con la ruta del galeón de Manila a través del Pacífico, Asia Oriental se vincula a América y se integra al flujo monetario generado por la producción de plata en Hispanoamérica. A cambio, gran cantidad de mercancías orientales inundan los puertos de las colonias españolas en América. A su vez, los comerciantes novohispanos adquieren un papel central en los intercambios entre México con Centroamérica y el Virreinato del Perú, al igual que con el Oriente por medio de la ruta del galeón de Manila. Este recorrido comercial prevalecería durante 250 años. También habrían de producirse numerosos flujos migratorios y la propagación de los cultivos de origen americano en el oriente asiático.

Esta reproducción produjo una serie de tópicos, tensiones y tendencias discursivas que incidieron, y lo siguen haciendo en el presente, en las relaciones de desventaja económica, social y política del istmo centroamericano con respecto a las potencias occidentales noratlánticas.
High glucose induces early senescence in adipose-derived stem cells by accelerating p16 and mTOR
Authors: Pham Hieu Liem , Pham Phuc Van
Published: July 2019

Introduction: The senescence of stem cells is the primary reason that causes aging of stem cell-containing tissues. Some hypotheses have suggested that high glucose concentration in diabetic patients is the main factor that causes senescence of cells in those patients. This study aimed to evaluate the effects of high glucose concentrations on the senescence of adipose-derived stem cells (ADSCs).

Methods: ADSCs were isolated and expanded from human adipose tissues. They were characterized and confirmed as mesenchymal stem cells (MSCs) by expression of surface markers, their shape, and in vitro differentiation potential. They were then cultured in 3 different media- that contained 17.5 mM, 35 mM, or 55 mM of D-glucose. The senescent status of ADSCs was recorded by the expression of the enzyme beta-galactosidase, cell proliferation, and doubling time. Real-time RT-PCR was used to evaluate the expression of p16, p21, p53 and mTOR.

Results: The results showed that high glucose concentrations (35 mM and 55 mM) in the culture medium induced senescence of human ADSCs. The ADSCs could progress to the senescent status quicker than those cultured in the lower glucose-containing medium (17.5 mM). The senescent state was related to the up-regulation of p16 and mTOR genes.

Conclusion: These results suggest that high glucose in culture medium can trigger the expression of p16 and mTOR genes which cause early senescence in ADSCs. Therefore, ADSCs should be cultured in low glucose culture medium, or normal glucose concentration, to extend their life in vitro as well as in vivo.
Initiation of Noninvasive Ventilation for Acute Respiratory Failure in a Pediatric Intermediate Care Unit
Authors: Smith Alla , Kelly Daniel P. , Hurlbut Julie , Melvin Patrice , Russ Christiana M.
Published: July 2019

BACKGROUND:

Noninvasive ventilation (NIV) is increasingly used to manage acute respiratory failure in children, decreasing the need for mechanical ventilation. Safely managing these patients outside of the ICU improves ICU resource use. We measured the impact of a guideline permitting initiation of NIV in an intermediate care unit (IMCU) on ICU bed use.

METHODS:

A guideline for an NIV trial for acute respiratory failure was implemented in a 10-bed IMCU. The guideline stipulated criteria for initiation and maintenance of NIV. There were 4.5 years of intervention data collected. Baseline data were gathered for patients with acute respiratory failure who were transferred from the IMCU to the ICU for NIV initiation in the 3.25 years before guideline implementation.

RESULTS:

Three hundred eight patients were included: 101 in the baseline group and 207 in the intervention group. In the intervention group, 143 patients (69%) remained in the IMCU after NIV initiation, and 64 (31%) transferred to the ICU. A total of 656.4 ICU bed-days were saved in the intervention period (3.3 days per patient initiated on NIV in the IMCU). There was a significant decrease in the rate of intubation in the IMCU for patients awaiting ICU transfer (3 patients in the baseline group versus 0 patients in the intervention group; P = .035).

CONCLUSIONS:

The initiation of NIV in the IMCU for pediatric patients with acute respiratory failure saved ICU bed-days without increasing intubation in the IMCU for patients awaiting transfer. Close monitoring of these critically ill patients is a key component of their safe care.
O refúgio esquivo: Nietzsche e Heidegger sobre arte e niilismo
Authors: Drucker Claudia
Published: July 2019

Tanto Nietzsche como Heidegger consideram o niilismo uma ameaça, mas divergem quanto à definição do fenômeno e quanto à resposta ser dada. Heidegger reluta em apontar uma saída, seja através da arte ou da ação, já que também as soluções propostas podem ser formas de reforçar o niilismo.
Levinas et la médiation impensée
Authors: Ciaramelli Fabio
Published: July 2019

O texto investiga a constituição da subjetividade ética no pensamento de Levinas, com especial ênfase na estrutura de mediação que estrutura faticamente o sentido da irrupção da alteridade no universo auto-referente do “mesmo”, em termos de uma “ética temporalizada”.
Liberdade em Hegel
Authors: Utz Konrad
Published: July 2019

As normas da moral são as regras sob as quais o indivíduo livre limita livremente sua liberdade em prol da liberdade geral. As normas da lei (quando esta for justa) são regras sob as quais o indivíduo livre é forçado a limitar sua liberdade em prol da liberdade geral. Com isso quase todos os filósofos modernos concordam. A ideia genial e central da filosofia prática de Hegel é que as normas tanto da moral quanto da lei não são limitações da liberdade, mas o cumprimento dela, porque nelas e somente nelas a liberdade se realiza. O conceito dessa realidade geral da liberdade nas normas éticas é a “eticidade”. Essa concepção Hegel desenvolve a partir da reflexão, necessariamente chega à compreensão de que o cumprimento pleno de sua liberdade consiste na eticidade. O presente artigo tenta expor esse nexo lógico-conceitual. Em seguida, oferece algumas indicações concretas para a situação política atual, para, por fim, apontar um defeito que inclusive o conceito hegeliano de liberdade tem.

Detrascendentalizing subjetivity: Paul Ricoeur's revelatory hermeneutics of suspicion
Authors: De Oliveira Nythamar
Published: July 2019

O artigo esboça o desenvolvimento da hermenêutica filosófica de Paul Ricoeur a partir de sua fenomenologia da vontade em direção a uma hermenêutica da revelação, mostrando como o projeto radical de destranscendentalizar a subjetividade, subjacente à recepção francesa copntemporânea de uma hermenêutica da suspeita, terma por favorecer um retorno pós-hegeliano a Kant e reformula a filosofia transcendental numa correlação histórica e socialmente mediada entre linguagem e subjetividade, juntamente com uma dialética entre poesis e práxis.

Historicidade e hermenêutica, condições para o diálogo entre a ciência e a ética
Authors: Ruiz Castor Bartolomé
Published: July 2019

Na modernidade, ciência e ética raramente conviveram em harmonia. Sua relação conflitante sempre demarca sobre os tipos de verdade de ambos discursos. A construção de qualquer consenso entre os discursos científico e ético se mantém sobre uma base instável de mútua desconfiança. Essa instabilidade implica, comumente, um confronto permanente entre as verdades e os critérios de ambos discursos. O conflito entre ciência e ética se dá, essencialmente, no campo da teoria da linguagem, ou seja, na análise do discurso. As pretensões de verdade e os efeitos de poder das verdades científicas e éticas, são correlativos ao reconhecimento da verdade de suas proposições e da validade do seu discurso. Para contribuir com alguns esclarecimentos neste debate entre ciência e ética, deveremos, pois, nos introduzir em alguns pontos da teoria da linguagem, ou seja, na historicidade e na hermenêutica.

Neste estudo, tratarei de dois modelos que são representados através das duas metáforas “níveis” e “redes” e são de grande significado para os debates contemporâneos em filosofia da mente e teorias de decisão. Após distinguir os dois modelos de modo geral, ambos os padrões de estrutura serão analisados com referência ao problema da liberdade da vontade e do controle de ações, discutindo, na conclusão, a sua compatibilidade.
Conservação de si e modernidade - Uma abordagem crítica aos conceitos de bioéticameio ambiente e
Authors: Heck José
Published: July 2019

O esforço de perseverar na existência substitui, na Modernidade, o milenar imaginário finalista do desejo governado pela reta razão. Entre nascimento e morte, a conservação de si marca a singularidade humana e tece a irredutível individualidade de nossas vidas. As pesquisas ambientais e os estudos de biótica retornam das nascentes da racionalidade moderna com o mapa da incomensurabilidade dos conflitos e o enigma de uma era perdida. A articulação do presente artigo é feita na contramão da opinião pós-moderna dominante. O texto argumenta a favor da expansão estatal da responsabilidade difusa para lidar a contento com os desafios complexos do mundo contemporâneo.
O Sumo Bem e a relação moralidade e felicidade na Crítica da Razão Pura de Kant
Authors: Nodari Paulo César
Published: July 2019

Esse artigo tem como propósito mostrar que a moralidade e a felicidade são dois elementos do Sumo Bem. Buscar-se-á, então, em primeiro lugar, elucidar a tese de que o Sumo Bem é o objeto da razão prática pura; em seguida, explicitar-se-á a importância da distinção entre saber e acreditar, salientando, portando, que esta distinção é muito importante para a compreensão dos postulados da razão prática pura, ou seja, para a compreensão dos limites da razão em seu âmbito, especulativo e prático. Por fim, elucidar-se-á que a felicidade, apesar de ela não ser considerada o princípio da moralidade, recebe consideração imprescindível na ética kantiana, sendo denominada por Kant na Crítica da razão prática, o segundo elemento do Sumo Bem.
Pessimismo dialético versus liberalismo político filosófico
Authors: Heck José Nicolau
Published: July 2019

Tendo como pano de fundo o materialismo histórico e o empirismo lógico, o trabalho expõe brevemente o ressurgimento da filosofia política, com a obra Uma teoria da Justiça (1971), de John Rawls, e a revisão radical da mesma, numa concepção adequada ao pluralismo, em Liberalismo Político (1993). Após confrontar a razão pública do liberalismo política com o conceito do político de Carl Schmitt, procura-se formular uma avaliação do pluralismo de Rawls e confrontá-lo com o pluralismo multicultural e com a legalidade apático-consencual das democracias paternalistas pós-modernas. Na conclusão, pronuncia-se contra a mera fidelidade constitucional e posiciona-se a favor de um direito positivo amparado explicitamente no liberalismo político-filosófico da modernidade.
