Published: November 2017

A qualidade e a segurança dos alimentos são fatores importantes na tomada de decisão pelos consumidores. Este trabalho de pesquisa visa conhecer a percepção dos consumidores quanto à qualidade nutricional e tecnológica dos produtos alimentares e conhecer seus hábitos de compra. Trata-se de um estudo observacional, descritivo e transversal baseado na aplicação de um questionário a 200 sujeitos que se deslocaram a três superfícies comerciais do Concelho de Bragança entre Abril e Julho de 2015. Do total de sujeitos questionados, 52,5% eram do gênero masculino. A maioria tinha entre 18 e 24 anos (50,5%), era casado ou vivia em coabitação (72,4%), possuía como habilitações literárias o ensino secundário (52,5%) e tinha uma renda mensal líquida inferior a 1789 USD (81%). A maioria dos consumidores disse que leva em conta o valor nutricional dos alimentos que consome (63,5%), embora apenas 43,2% estejam acostumados a avaliar a tabela nutricional. O que atrai a maior atenção dos consumidores no rótulo é a validade (51%), os ingredientes (31,7%), a tabela nutricional (16,1%) e, por último, a marca (8%). Geralmente, na opinião dos consumidores, os fatores mais importantes em uma compra relacionada à qualidade de um produto são a nutrição (50,8%), a higiene (31,7%) e o preço (23,1%). Para o consumidor, as tecnologias são importantes e contribuem para aumentar o valor nutricional dos produtos alimentares (53,5%), destacando a irradiação (26,9%), os aditivos e conservantes (20,3%) e a secagem (15,3%) como as mais prejudiciais do ponto de vista nutricional. O consumidor espera obter alimentos de maior qualidade nutricional, saudável e tecnológica em grupos como as frutas (61,4%), as leguminosas (57,7%) e os cereais (41,6%). Os consumidores são, atualmente, mais exigentes com a qualidade dos produtos alimentares. Nesta pesquisa, destacam-se fatores como a “nutrição” e a “higiene”.
Drombeg Stone Circle, Ireland, analyzed with respect to sunrises and lithic shadow-casting for the eight traditional agricultural festival dates and further validated by photography
Authors: Meaden G. Terence
Published: November 2017

A new survey of Drombeg Stone Circle and accurate analysis of shadow effects beginning at particular sunrises of the calendar year has led to a breakthrough in the understanding of lithic symbolism and the intentions behind the construction of this and other Irish monuments including Knowth and Newgrange that also have astronomical alignments. At Drombeg specific standing stones play critical roles at sunrise for all eight of the festival dates as known traditionally and historically for agricultural communities and as now inferred for prehistoric times following the present observation-based analysis.Crucial for Drombeg in the summer half of the year is the positioning of a tall straight-sided portal stone such that its shadow at midsummer sunrise encounters an engraving on the recumbent stone diametrically opposite. During subsequent minutes the shadow moves away allowing the light of the sun to fall on the carved symbol. It is the same for sunrises at Beltane (May Day), Lughnasadh (Lammas), and the equinoxes when shadows from other perimeter stones achieve the same coupling with the same image, each time soon replaced by sunlight. For the winter half of the year which includes dates for Samhain, the winter solstice and Imbolc, the target stone for shadow reception at sunrise is a huge lozenge-shaped megalith, artificially trimmed. Moreover, for 22 March and 21 September there is notable dramatic action by shadow and light between a precisely positioned narrow pillar stone and the lozenge stone.As a result, at sunrise at Drombeg eight calendrical shadow events have been witnessed and photographed. This attests to the precision of Neolithic planning that determined the stone positions, and demonstrates the antiquity of the calendar dates for these traditional agricultural festivals. Discussion is held as to what the concept of shadow casting between shaped or engraved stones at the time of sunrise may have meant in terms of lithic symbolism for the planners and builders. This leads to a possible explanation in terms of the ancient worldview known as the hieros gamos or the Marriage of the Gods between Sky and Earth.
Stonehenge and Avebury: Megalithic shadow casting at the solstices at sunrise
Authors: Meaden G. Terence
Published: November 2017

The paper examines how specific megaliths at Stonehenge and Avebury were positioned relative to others and to particular sunrises such as to produce watchable effects arising from solar movement and resulting lithic shadows. At Stonehenge and environs numerous research expeditions (exceeding 120 that started in 1981) combined with accurate compass analysis, photography and studies of the best plans of the sarsen-stone and bluestone phases have led to explanations for apparent anomalies of stone positioning that have not been clarified before.Firstly, at the summer solstice in the Late Neolithic the Altar Stone was illuminated by sunshine for the first three or four minutes of the day, following which the shadow of the round-topped Heel Stone was cast into the middle of Stonehenge to reach the Altar Stone. This circumstance continues to be witnessed today. It is a consequence of the Heel Stone being deliberately offset from the Stonehenge axis of symmetry. Again, there is the offset positioning of the anomalous half-height, half-width, Stone 11 that disrupts the otherwise regular arc of the lintelled sarsen circle. It is also a fact that the Altar Stone, although on the midsummer sunrise axis and bisected by it, does not lie perpendicular to the monument’s axis but is instead angled lengthways in the direction of the winter solstice sunrise. The same is true of the orientation of the Great Trilithon (as recently discussed by T. Daw). This suggests that the Altar Stone and the Great Trilithon were deliberately positioned this way in order to respect and emphasise an older arrangement in which a midwinter sunrise megalithic setting had been important. Such an arrangement involving the winter solstice sunrise still exists because the shadow of the short round-topped Stone 11 at sunrise appears aimed at the rhyolite ignimbrite Bluestones 40 and 38 - both of which are damaged, fallen and possibly parts of a single original. In similar manner the site of Hole G could indicate the former position of an ancestral stone with regard to equinoctial sunrises. Thus, these shadow-casting experiences for sunrise at Stonehenge may have affinities with the proven stone-to-stone casting of shadows for the same significant calendar dates at the carefully examined Drombeg Stone Circle. At Avebury the stones of the Cove in the northern circle together with Avebury’s Stone F harmonize likewise at the summer solstice sunrise. Two surviving megaliths in Avebury’s southern circle behave similarly. It is discussed whether an explanation in terms of the ancient worldview of the hieros gamos between Sky and Earth may be appropriate for Stonehenge and Avebury as it could also be at Drombeg.
Knowth passage-grave in Ireland: An instrument of precision astronomy?
Authors: Prendergast Kate
Published: November 2017

Knowth is one of three large monuments at the Neolithic complex in the bend of the River Boyne in County Meath, Ireland. The others are Newgrange and Dowth. All three have obvious solar alignments but whereas the alignment to the winter solstice sunrise at Newgrange has been extensively researched and interpreted, little has been attempted regarding the way that astronomy functions at Knowth and Dowth. This paper treats the evidence for solar and lunar alignments at Knowth. Knowth has two internal passages with entrances at the east and west. The paper draws on new surveys as well as interpretations of the evidence at Knowth that includes rock art engraved on kerbstones around the circumference. Particular engravings on kerbstone K52 are interpreted as depicting astronomical cycles. It is argued that, while Knowth’s passages function in relation to the equinoxes, they are not internally orientated to match exactly the equinoctial directions. Rather, it seems that they may have been constructed and used to facilitate the harmonisation of the solar and lunar cycles - much in the same way as does the equinoctial Judeo-Christian festival of Easter. The paper concludes by suggesting that like Newgrange, Knowth may be an astronomical instrument that enabled its builders and users to construct accurate calendars and counting systems, which in turn facilitated calculated planning and was a fundamental structuring principle for their ritual lives and cosmological beliefs.

Published: November 2017

Crash box design as one of the passive safety components in a vehicle had been developed to enhance energy absorption. Initial fold on the crash box is set to facilitate folding during the crash. The aims of this study is to investigate the initial folded crash box with length to thickness ratio subjected to frontal test. The frontal test is modelled by using finite element analysis. Through computer simulation using 9 models, the obtained result was used to provide the better design of crash box. The variations in this study were length to thickness ratio of crash box with length of tube (L) = 115; 132.5; 150 mm and the thickness of tube (t) = 1.6; 2.0; 2.5 mm. The crash box material was assumed as bilinear isotropic hardening material. The velocity used in the simulations was 7.67 m/s with impact mass of 103 kg. Based on the results, it can be shown that 1st model to 8th model produce deformation pattern as concertina mode and 9th model has diamond mode. The 3rd model has the largest energy absorption with value 18.29 kJ.

Published: November 2017

Abstract                  The experimental study of the influence of process parameters towards collar height on incremental backward hole-flanging (IBHF) process with aluminium plate workpiece was presented in this paper. The effect of process parameters toward collar height which produced by IBHF process was investigated. Experiments were performed with a CNC machine, a 30o conical forming tool, and aluminium plates. The process parameters are feed speed with two levels, radial forming step size with three, and axial forming step size with three levels. Some parameters were kept constant, i.e., spindle speed, initial hole diameter, final hole diameter, and conical forming tool diameter. Digital Vernier caliper was used to measure the height of the collar. Experimental results of IBHF process have shown that the feed speed (vf) parameter has no effect toward collar height. Increased radial forming step size (Δx/y), increased the collar height also. Increased the axial forming step size (Δz) reduced the collar height. Keywords: hole-flanging, incremental sheet metal forming, incremental backward.

Authors: Hariyadi Setyo
Published: November 2017

Winglet attached on the tip of aircraft wings to increase lift. Mainly, winglet used for increasing aerodynamic efficiency, it decreases induced drag caused by vortex on wings tip. The phenomenon of vortex is collision of high-pressured air below the wings meet the low-pressured air above it that cause turbulence. Induced drag may reach 40% of total drag during cruising, and 80-90% while take off. A procedure to decrease induced drag is using wing tip devices. It used on commercial aircrafts and the most frequently used is blended winglet. Numerical study conducted to examine the best aerodynamic performance of sub-sonic plane wings in angles of attack. Analysis on NACA 23018 airfoil wings with blended winglet on the tip was conducted. Freestream velocity of 40 m/s or Re = 1 × 106, and angle of attack (α) 0o, 5o, 10o, and 15o are used. Evaluation for parameter includes coefficient pressure (Cp), velocity profile, lift, drag, and ratio CL/CD. Obtained contour are pressure contour, velocity, and vorticity. In view of all this, there is increasing performance of aerodynamic with CL/CD ratio of wings with blended winglet and plain wing. Reaching current angle of attack, the function of winglet is gradually decrease.
MAIN OBJECTIVES OF STATE LAND CONTROL (OVERSIGHT) MANAGEMENT ON THE EXAMPLE OF LAND PLOTS OF MOSCOW REGION
Authors: Sinenko V A
Published: November 2017

Human use of the land resources of the Russian Federation for the provision of social and financial aspects of life activity is a kind of anthropogenic impact on the component of the natural environment - land. The earth, being a natural object and a natural resource by virtue of Art. 4 of the Federal Law from 10.01.2002 No. 7-FZ On Environmental Protection is considered the subject of en-vironmental protection from pollution, depletion, degradation, spoilage, destruction and other negative effects of economic and other work. The data of the governmental ecological forecast show that the eco-logical state of land resources undergoing intensive anthropogenic influence tends to deteriorate. Problems of improving the ecological status of territories occupy an important place in modern state-wide land and environmental policies. The land as an object of immovable property is considered to be an object of protec-tion of property from violations of the legal procedure for the use of land (non-targeted use of land), viola-tions of the rights of participants in land relations (unauthorized occupation of lands, destruction of land boundaries, illegal disposal). Thus, government land control over the use and protection of the territory as a natural object, land resource and real property should be carried out by officials at the municipal level.
DA FINANCEIRIZAÇÃO AO LUGAR: DOS NEXOS HEGEMÔNICOS ÀS CONTRA-RACIONALIDADES DO COTIDIANO
Authors: Montenegro Marina Regitz
Published: November 2017

As finanças alcançam, no período atual, uma centralidade inédita em todos os campos da vida social, assumindo um papel determinante sobre as dinâmicas do espaço geográfico (SANTOS, 1996; FRENCH et al., 2011). Na medida em que envolve transformações na economia, na política e na sociedade como um todo (CHRISTOPHERSON et al., 2013), a financeirização implica uma renovação dos próprios conteúdos do território e do cotidiano. Partindo de uma aproximação teórica sobre o processo em tela, o artigo busca desvendar certos nexos da creditização do território brasileiro para, em um segundo momento, focar a capilaridade alcançada pelas finanças entre a população pobre e seus impactos no cotidiano, onde a incorporação de nexos financeiros se combina à emergência de novas contra-racionalidades.

Vertical integration in the Brazilian orange juice sector: power and transaction costs
Authors: Ito Nobuiuki Costa , Zylbersztajn Decio
Published: November 2017

This paper aims to investigate the role of market power on vertical integration choices in the Brazilian orange juice sector. The main hypothesis states that market power, along with economizing drivers, has had an important role in the economic organization of the orange juice sector. In order to accomplish this task, we examine the make-or-buy decision of juice-processing firms in procurement of inputs (fruits), through a 15-year panel of five firms (more than 90% of the market). Empirical results offer new theoretical insights on role of market power in vertical integration decision. From these theoretical advancements, as implications for practitioners, market power raises attention for critical strategizing issues and antitrust remedies.
Technical efficiency and marketing channels among small-scale farmers: evidence for raspberry production in Chile
Authors: Jara-Rojas Roberto , Bravo-Ureta Boris E. , Solís Daniel , Arriagada Daniela Martínez
Published: November 2017

This study analyses technical efficiency (TE) levels among small-scale raspberry producers in Central Chile. Special attention is given in to investigate the impact of the marketing channel used by the farmers on their technical performance. The data used in this study were obtained from a farm-level survey of 139 small-scale raspberry farmers. A stochastic production frontier model was used to evaluate the association between TE, extension, training and farmers’ decisions to sell their production directly to the agro-industry or indirectly through an informal middleman. The empirical results show that the decision to sell raspberries using informal channels is negatively associated with farm productivity and revenues. The analysis also reveals a positive relationship between TE and income among experienced and trained farmers. Implementing food quality and safety standards was also found decisive in increasing farm income. Policy implications stemming from these results are also discussed.

Authors: Schutz Nathaly Xavier
Published: November 2017

Os problemas de segurança do Continente Africano são, em sua grande maioria, originários dos processos de colonização e descolonização ocorridos ao longo dos séculos XIX e XX. Na África Austral, em específico, o regime do apartheid da África do Sul marcou de maneira bastante expressiva a construção de uma identidade comum e a aproximação entre os demais países da região em torno dos temas de segurança. O objetivo desse trabalho é avaliar a evolução da SADC ao longo dos anos 90 e 2000 no tocante aos aspectos securitários, visando analisar em que medida a organização contribuiu ou não para a resolução dos problemas políticos e de segurança da região, em especial nos momentos de crise. A análise será concentrada na criação e nas modificações do Órgão para a Cooperação em Política, Defesa e Segurança (OPDS) da Comunidade para o Desenvolvimento da África Austral (SADC). A hipótese central do trabalho é de que a SADC, e o OPDS em específico, constituem a principal esfera de tratamento das questões securitárias da África Austral e, ao longo dos anos, contribuiu para evolução da resolução desses problemas. O trabalho irá utilizar a revisão bibliográfica e documental, adotando uma abordagem histórica, visando uma comparação temporal do caso em questão.
RELAÇÕES BRASIL-PALOP: 40 ANOS DE COOPERAÇÃO PARA O DESENVOLVIMENTO NO ATLÂNTICO SUL (1974/75-2015)
Authors: Rizzi Kamilla Raquel
Published: November 2017

A comemoração dos 40 anos das independências dos Países Africanos de Língua Oficial Portuguesa (PALOP) é basilar para compreender-se a evolução histórico-social, econômica e de inserção no sistema mundial dessas ex-colônias portuguesas na África. As experiências socialistas nas décadas de 1970 e 1980, os condicionantes externos, a reforma econômica e a evolução para o multipartidarismo na década de 1990 e a tentativa de estabilização e desenvolvimento na década 2000 demonstram um panorama de acertos e erros na construção dos cinco jovens países. Este artigo analisa historicamente o trajeto político, econômico, social e diplomático percorrido pelos cinco PALOP, partindo da argumentação de que esses países (embora se mantendo na órbita da ex-metrópole, especialmente após a década de 1980), se aproximaram estrategicamente do Brasil como premissas políticas e culturais básicas para sua sobrevivência no sistema mundial.
Boron removal from aqueous solutions by a polyethylenimine-epichlorohydrin resin
Authors: Sarri Sofia , Misaelides Panagiotis , Zamboulis Dimitrios , Warchoł Jolanta
Published: November 2017

The use of a polyethylenimine?epichlorohydrin resin for the boron removal from aqueous solutions (boron concentration: 100?5000 mg L-1) of non-adjusted and pre-adjusted pH (pHnat, pHinit 8.0, 9.0 and 10.0) aqueous solutions was investigated using a batch technique. The boron concentration in the solutions after sorption was determined photometrically. The results indicated that the pH-dependent boron uptake was related to the protonation/deprotonation of the surface functional groups of the resin and to the boron speciation in solutions of different pH values. The maximum boron sorption capacity observed in solutions of pH 9.0 was 55 mg g-1 exceeding the majority of other commercial or alternative sorbents. Five empirical adsorption equations (Freundlich, Langmuir, Redlich?Peterson, Langmuir?Freundlich and Toth) were applied to the modelling of the boron adsorption equilibrium. The modelling results identified the homogenous boron sorption from acidic and heterogeneous from alkaline solutions. At alkaline pH, the system non-ideality can originate either from the different binding mechanism or from the competitive sorption of different boron species. The homogenous type boron sorption from acidic solutions was further confirmed by kinetic studies

Anthropogenic activities, urbanization and industrialization cause an increase in the atmospheric carbon dioxide. Current focus of the soil scientists and the environmentalists is to quantify the carbon stocks and its flow in the agroecological system which is one of the main causes of global warming and climate change. The information on the distribution of soil organic carbon (SOC) stocks in the soil profiles in relation with changing climate is barely sufficient. Objective of this study was to quantify the effect of climate and land on the equilibrium of SOC stocks in soil profiles with development. Murree soil series (Typic Hapludolls) in humid climate and under coniferous forest, and Tirnul soil series (Typic Haplustepts) in semiarid climate under cultivation, were selected. Triplicate soil profiles were selected for each of the soils and sampled at genetic horizons level. Cumulative SOC stocks in Typic Hapludolls soil profiles (95 Mg ha-1) were significantly greater than Typic Haplustepts (30 Mg ha-1). The Typic Hapludolls had significantly greater SOC stock at each horizon level under humid climate. This research concludes that soils under forest and humid climate had higher SOC stocks as compared to the soils under semiarid climate and cultivation.
Nаture and human in the age of biotechnologies
Authors: Stojic Gordana
Published: November 2017

The rapid development of biotechnology in recent decades has brought about
the debate over the consequences of genetic modification of living organisms.
Opposing views are particularly pronounced when it comes to the possibilities
of biotechnological human enhancement. Margaret Atwood?s dystopian novel Oryx
and Crake shows the final outcome of a development trend that has existed
since the emergence of modern society - a combination of science, technology
and capitalism supported by the ideology of progress. The paper deals with
the problem of boundaries between natural/unnatural, human/animal in the
future world which turned into ?one vast uncontrolled experiment? by the
application of biotechnologies. Based on the analysis of the Atwood`s novel,
the paper aims to present arguments for and against genetic engineering and
human enhancement. Two problems are analyzed: what is natural and what is
human uniqueness. The problem of the human in the novel is shown on several
levels: animal and human hybrids, the posthuman people and former human.
Atwood shows that the arguments in defense of nature are powerless against
the logic of profit and deep-rooted human domination over nature. When it
comes to man, the uniqueness of human nature is disrupted by reducing the man
to the object of study of natural sciences which makes social, cultural and
emotional characteristics of man unnecessary and obsolete. If there is no
idea of the uniqueness of life and of human nature, it is difficult to answer
the question - ?how much is too much, how far is too far? when we interfere
with nature, life and human.
Subclinical First Trimester Renal Abnormalities Are Associated With Preeclampsia in Normoalbuminuric Women With Type 1 Diabetes

OBJECTIVE

This study was conducted to determine the utility of tubular (urinary/plasma neutrophil gelatinase-associated lipocalin [NGAL] and urinary kidney injury molecule 1 [KIM-1]) and glomerular (estimated glomerular filtration rate [eGFR]) biomarkers in predicting preeclampsia (PE) in pregnant women with type 1 diabetes mellitus (T1DM) who were free of microalbuminuria and hypertension at the first trimester.

RESEARCH DESIGN AND METHODS

This was a prospective study of T1DM pregnancy. Maternal urinary and plasma NGAL, urinary KIM-1 (ELISA of frozen samples), and eGFR (Chronic Kidney Disease Epidemiology Collaboration equation) were determined at three study visits (V1: 12.4 ± 1.8; V2: 21.7 ± 1.4; V3: 31.4 ± 1.5 weeks’ gestation [mean ± SD]) in 23 women with T1DM with subsequent PE (DM+PE+), 24 who remained normotensive (DM+PE−), and, for reference, in 19 normotensive pregnant women without diabetes (DM−). The groups with diabetes were matched for age, diabetes duration, and parity. All subjects were normotensive and free of microalbuminuria or albuminuria at V1. All study visits preceded the onset of PE.

RESULTS

Urinary creatinine-corrected NGAL (uNGALcc, ng/mg) was significantly elevated at V1 in DM+PE+ vs. DM+PE− women (P = 0.01); this remained significant after exclusion of leukocyte-positive samples (5 DM+PE+ and 2 DM+PE−) (P = 0.02). Accounting for BMI, HbA1c, and total daily insulin dose, a doubling of uNGALcc at V1 conferred a sevenfold increase in risk for PE (P = 0.026). In contrast, neither plasma NGAL nor urinary KIM-1 predicted PE. Also at V1, eGFR was elevated in DM+PE+ vs. DM+PE− (P = 0.04).

CONCLUSIONS

Early tubular and glomerular dysfunction may predict PE in first trimester women with T1DM, even if free of microalbuminuria. These data suggest that subclinical renal tubular and glomerular injury, if present early in pregnancy, may predispose women with T1DM to PE.

El propósito de este trabajo es elaborar una crítica sistemática a la teoría de los sistemas complejos (TSC) formulada por Rolando García, con el fin estratégico de contribuir a desarrollarla como un programa de investigación interdisciplinario en sistemas complejos con alcances sociales y políticos. Se plantean nueve críticas, y para cada una se ofrece la problematización conceptual de un aspecto insuficientemente tratado o no tematizado por la TSC y se sugiere, a modo de hipótesis, una vía posible para su desarrollo.
Comparison of Two Concentrations of Triamcinolone Injection in the Prevention of Supratip Edema after External Rhinoplasty: A Randomized Trial
Authors: Saedi Babak , Amali Amin , Arabpor Mina
Published: November 2017

Background

A comparison of the two methods of corticosteroid (triamcinolone) use in reducing supratip edema (pollybeak deformity) after rhinoplasty.

Methods

Ninety patients who were candidates for rhinoplasty were randomly divided into three groups. Group A received no treatment, group B received 8 mg/mL of triamcinolone, and group C received 16 mg/mL of triamcinolone. Their effects on dorsal edema were evaluated by using the patients' and surgeons' visual analog scale scores. Also, dorsal edema was measured by using photo editing software.

Results

There was no significant difference in the patients' characteristics in the study groups. The surgeons' visual analog scale scores were significantly better in those patients who received triamcinolone injection than in the control group (p = 0.02). However, none of the other assessment methods showed significant differences among the study groups. There was no significant difference between the two evaluated concentrations.

Conclusion

Triamcinolone injection had positive temporary effects on reducing supratip edema without any important complications.

Published: November 2017

Background

A novel, bioabsorbable, fibrinogen-based implant has been developed as a mucosal dressing after endoscopic sinus surgery (ESS). This implant can be formulated with fluticasone propionate (TP) for local elution of corticosteroid to reduce postoperative inflammation and promote mucosal healing.

Objective

This study investigated the biocompatibility and pharmacokinetics of the implant in a rabbit model.

Methods

Implants with and without TP were placed on both intact and demucosalized maxillary sinuses of 33 New Zealand White rabbits. Sinuses with either intact or denuded bone without implants acted as controls. Histopathologic assessments were carried out at 5, 15, and 28 days. Concentrations of TP in the maxillary sinus mucosa, nasal cavity mucosa, and plasma were measured for up to 44 days.

Results

Implants placed on intact mucosa or denuded bone were grossly integrated within 15 days. Minimal foreign body reaction was seen with negligible differences for inflammation, fibrosis, or bone remodeling among controls, sinuses with the implant, or sinuses with the implant plus TP, at all time points. All samples also showed complete or near-complete percentage reepithelialization at 28 days, although the denuded bone controls demonstrated greater percentage reepithelialization at 5 days compared with denuded bone with the implant or implant plus TP (p <0.0001). The maxillary sinus mucosa demonstrated levels of TP of >140 ng/g up to 44 days. Plasma concentrations of TP were generally very low and were undetectable after day 7.

Conclusions

The implant and the implant plus TP seemed to be biocompatible in rabbits. The implant plus TP effectively eluted steroid locally over at least 44 days, with negligible plasma concentrations. Further studies are warranted regarding potential therapeutic applications in patients undergoing ESS for chronic rhinosinusitis.

Background

Currently vitamin D3 (VD3) or cholecalciferol is considered an immunomodulator that may be implicated in nasal polyposis (NP) pathophysiology.

Objectives

This study aimed to investigate if deficiency of VD3 is associated with the presence of NP in patients with cystic fibrosis (CT) and patients with chronic rhinosinusitis (CRS).

Methods

In total, 152 adult participants were included in five phenotypic groups: CT with NP (CTwNP) (n = 27), CT without NP (CTsNP) (n = 31), CRS with NP (CRSwNP) (n = 32), CRS without NP (CRSsNP) (n = 30), and controls (n = 32). The serum levels of 25(OH)-VD3 <20 ng/mL are considered as a deficiency, 21–29 ng/mL as insufficiency, and >30 ng/mL as sufficiency. Endoscopic and imaging staging of the mucosal disease performed with the Lund-Kennedy (LK) and Lund-Mackay (LM) scoring systems, respectively. The genotype of the patients with CT and the nasal microbial colonization of the patients with CT and patients with CRS were also recorded.

Results

The patients with CTwNP had the lowest percentage of sufficiency in VD3 and the highest percentage in insufficiency among all the groups. The LM imaging scores were inversely correlated with the VD3 levels in both arms of the study (CT and CRS). Moreover, the LK endoscopic scores had a similar correlation in the CT groups; however, this was not the case with the CRS groups. The genotype of the patients with CT was not correlated with the VD3 serum levels. The patients with positive microbial colonization (mainly Pseudomonas and Staphylococcus aureus) had significantly lower VD3 serum levels in both the CT and CRS process.

Conclusion

VD3 deficiency seemed to be associated with the presence of nasal polyps in the patients with CRS and in the patients with CT in a similar manner. The lower the level of serum VD3, the more severe the mucosal disease was found in the imaging studies and the more frequent microbial colonization of the patients with CT and the patients with CRS.
O NASCIMENTO DA PINTURA MODERNA
Authors: Dantas Marta
Published: November 2017

A História da Arte não é a história das aplicações progressivas de princípios estéticos. pelo contrário é o  relato da quebra de valores  estéticos e socioculturais. O nascimento da Arte moderna representa uma ruptura radical de valores estéticos que tiveram origem no Renascimento, o que nos permite considerar os acontecimentos ligados ao mundo das artes, na segunda metade do século XÍX, como uma "revolução estética". Revolução esta que pôs fim ao imaginário coletivo, aos modelos de beleza, a concepção de mundo hierarquizado e fez emergir uma percepção essencialmente individual.

Avaliação do Recrutamento Celular no Modelo Experimental da Esquistossomose Mansônica
Authors: Larocca Rafael Assumpção
Published: November 2017

Sendo a Esquistossomose uma doença de grande importância médica, o conhecimento específico da reação inflamatória, assim como o entendimento da resposta imune induzida pelo S. mansoni, nos motivou neste estudo. Alguns pesquisadores demonstraram que, em modelos de cobaias ocorre reações inflamatórias induzidas por este helminto no fígado, assim como no homem. Desta forma, avaliamos a migração de leucócitos para diferentes compartimentos, e identificamos alterações histopatológicas promovidas pela parasita. Nossos achados, demonstraram aumento absoluto e percentual de eosinófilos na cavidade peritoneal e sangue de camundongos infestados pelo S. mansoni. As figuras histológicas confirmaram os achados da cavidade peritoneal onde houve um aumento significativo de eosinófilos, sugerindo que estas células migraram para a cavidade peritoneal posteriormente ao seu aumento no sangue caracterizando a resposta inflamatória intensa na infestação pelo S. mansoni neste modelo experimental.

Considerando o papel fundamental da escola na formação de alunos que utilizem a leitura não só como meio de adquirir informações, mas como prazer, foi organizado um projeto para estimular o gosto pela leitura em crianças, com alunas de um curso de formação de professores para as séries iniciais.Seu principal objetivo é buscar fundamentos sobre o ato de leitura e sua função social bem como desenvolver ações e reflexões, visando a apresentar a leitura como instrumento de prazer. O projeto vem sendo desenvolvido com 80 crianças de uma instituição parceira - PROVIM. Os participantes, de 7 a 12 anos, residem em bairros de periferia da cidade, têm pouco contato com materiais escritos e dificuldade de acesso a textos, principalmente os literários. Semanalmente, são acompanhadas as atividades desenvolvidas pelas futuras professoras junto ao PROVIM, avaliando-se as estratégias utilizadas nas atividades de leitura bem como os registros dessas atividades, para posterior reflexão. Alguns resultados parciais do trabalho podem ser apontados tanto em relação à formação das futuras professoras como em relação à formação das crianças como leitores: obtenção de referencial conceitual para planejamento e avaliação das atividades de leitura com as crianças; seleção de textos adequados à faixa etária dos participantes; uso de recursos variados para contar histórias; melhoria da expressividade na leitura oral das histórias; maior participação das crianças na discussão das histórias lidas, demonstrando o entendimento de detalhes do texto. A atuação das futuras professoras, no projeto, tem contribuído para oferecer vivências de situações reais de sala de aula, complementando a formação recebida na graduação e preparando-as para uma ação docente mais eficaz na área de leitura.

Published: November 2017

A prática da odontologia abrange grande variedade de procedimentos, que podem incluir desde um simples exame clínico até uma cirurgia mais complexa. Estes procedimentos geralmente implicam em contato com secreções da cavidade bucal como saliva, sangue, secreções purulentas, respiratórias e aerossóis. O risco de transmissão de patógenos importantes tem despertado grande preocupação devido ao risco de exposição do paciente, do profissional e da equipe odontológica. Assim, recomenda-se que precauções padronizadas sejam utilizadas durante a rotina de tratamentos odontológicos. Deste modo, realizou-se este estudo com o objetivo de abordar aspectos importantes no controle dos fatores de risco à infecção cruzada na prática odontológica.
