In general, learning English is essential today. This language is very in demand for the best jobs, and is even a requirement to study at some universities. However, it is also key to learn it to be able to communicate with different people from all over the world. Thus, the English for tourism is essential. First of all, for a matter of communication. The possibility of assisting travelers, if you are a professional, is a necessity that will be demanded of you at work. And since English is a Universal language, spoken by millions of people, will be very helpful in different contexts. English phrases for travel are useful to communicate in a shop or hotel, ask for directions, learn something about local attractions and monuments, or simply not to get lost at the airport in the maze of English-language information. Knowledge of the English language in today’s world is really a necessity.

Seks dimensioner af adgang til kunst og kultur for ensomme ældre i Musikalske Besøgsvenner
Authors: Schneidermann Nanna , Bakkær Munk Andersen Amalie , Kronborg Hansen Tanja
Published: May 2024

Hvad vil det sige at have adgang til kunst- og kulturlivet? Det er ét af de spørgsmål som projektet Musikalske Besøgsvenner stiller. Igennem intimkoncerter i hjemmet undersøger projektet værdien af deltagelse i kulturlivet for brugere af besøgsvennetjenester og andre tilbud for sårbare borgere med mulige ensomhedsproblematikker. Denne rapport beskriver hvordan Musikalske Besøgsvenner har arbejdet med adgang til kultur og viser, hvordan adgang i denne sammenhæng er mere end blot fysisk adgang, men også indeholder hvad vi kalder dimensioner af social, sanselig, følelsesmæssig, tidslig og relationsbaseret adgang. Vi undersøger flerdimensionel adgang til kunst og kultur ved at udfolde deltagernes erfaringer, som vi har indsamlet igennem etnografisk feltarbejde. Igennem vores feltarbejde har vi brugt visuelle og deltagende metoder som en måde at skabe viden om de sanselige, sociale, stemningsmæssige aspekter af det kunstneriske møde. I løbet af processen med at arbejde med billederne og film fra koncerterne indså forskningsgruppen, at disse medier kan give læseren adgang til erfaringer fra musikalske besøgsvenner på en anden måde end teksten tillader. Derfor er rapporten her bygget op omkring billeder, filmklip og personlige historier fra Musikalske Besøgsvenner, som viser adgang til kunst og kultur som et flerdimensionelt forhold, og hvad netop dette koncertformat kan bidrage med i forhold til at give sårbare borgere adgang til musikalske møder. Vi viser, hvordan adgang til konventionel kunst- og kulturliv kan forstås relationelt, snarere end som et spørgsmål om at "aktivere" passive borgere. Adgang til kulturlivet er forbundet med komplekse økonomiske, socio-materielle og sociale relationer.

Published: May 2024

This study aimed to investigate the effect of Aspergillus niger on the nutritional composition and in vitro dry matter digestibility of wheat bran (WB) in solid-state fermentation. Two A. niger strains (ATCC 200345 or ATCC 52172) were used as inoculants in solid-state fermentation of WB. Wheat bran was sterilized at 121°C for 15 min and inoculated with A. niger strains at 105 spores kg-1 WB. Samples were incubated at 60°C for two days and dried at room temperature until reaching 90% dry matter. Crude protein (CP), ether extract (EE), ash, crude fiber (CF), hemicellulose, neutral detergent fiber (NDF) and acid detergent fiber (ADF) content and in vitro dry matter digestibility of WB and fermented WB were determined.

Published: May 2024

This study aimed to determine the impact of different irrigation levels as a drought factor on the water productivity and yield of Tosunbey variety wheat. Conducted between 2018 and 2020 at the Sarayköy Research and Application Station in Ankara Province, the experiment employed a randomized block design with three irrigation levels and three replications. Significant effects of irrigation levels on the yield and various morphological parameters of wheat plants were observed. The I100 treatment, which was irrigated up to field capacity, achieved the highest yield with an average of 6.55 tons ha-1 over the two growing seasons. In contrast, the rainfed treatment (I0) showed a yield reduction of approximately 80.99% and 77.77% compared to the I100 treatment across the two years, respectively. Water productivity analyses (IWP) revealed average values of 1.74 kg m-3 and 1.55 kg m-3 for the I100 and I50 treatments, respectively. The highest outcomes, both in terms of yield and water productivity, were obtained under the I100 irrigation management where irrigation was applied up to field capacity. Correlation analyses conducted during the study identified significant relationships between different drought stress applications and morphological parameters in wheat. These findings are expected to contribute to the understanding of optimal irrigation strategies to maximize water efficiency and enhance crop performance in wheat cultivation.

Development of Rule-Based Expert System for Variable Cost and Gross Profit Calculations of Agricultural Products: A Case Study
Authors: Şahin Oğuz , Topaloğlu Fatih
Published: May 2024

Cost and gross profit calculations of agricultural products are a comprehensive and difficult process. Many different parameters, such as soil cultivation, pruning, spraying, irrigation, storage, drying, harvesting, transportation, and marketing, need to be evaluated together. Currently, cost calculations of agricultural products are made with classical programs and simple mathematical methods. For this reason, the results vary depending on the person and organization making the evaluation. This creates some limitations, making cost planning, which is a dynamic process, unreliable. In the study, a rule-based expert system was developed for the cost and gross profit calculation of apricots. The expert system developed is called Apricot Information System (APRIS). The developed expert system aims to provide more accurate solutions by adding the precision and speed of the computer to the calculation process. The main contribution of this study is the development of a complete decision support set covering all processes from tillage to marketing and the design of rule-based user-system interaction. The designed system found the apricot variable cost calculation to be 1126.36 TL/da for 2020. This value largely overlaps with the values obtained from the field in the previous year. The developed expert system will be a platform that can be used in cost calculations of many agricultural products.
The Impact of Climate Change Adaptation Strategies on Food Security: A Global Perspective
Authors: Afiani Nur , Bozoğlu Mehmet
Published: May 2024

Climate change poses a serious threat to the agricultural sector due to its nature of being dependent on natural conditions. As a result, food productivity decreases by threatening global food security. This study aims to analyze the impact of climate change adaptation adopted by farmers on food security by providing impressions and perspectives from related studies. According previous studies, the variables of gender, education, family size, land size, livestock ownership, agricultural extension, access to credit, and climate information are factors that have a positive influence on farmers' decisions to adopt climate change strategies. Meanwhile, the age variable has a negative influence on farmers' decisions to adpot it. In addition, the results also show that the adaptation of climate change strategies has a significant impact on food security. Farmers will gain more benefits and beneficial impacts from implementing climate change adaptation that limits the negative impacts of climate change on household livelihoods in an effort to alleviate food insecurity. This study provides important insights for future research on developing climate-resilient approaches to address complex global food system challenges.

Ser Humano entre a Angústia e a Coragem
Authors: Dumer Pablo Fernando
Published: May 2024

Este artigo é um estudo sobre antropologia teológica. Baseia-se, sobretudo, no teólogo protestante teuto-estadunidense Paul Tillich em diálogo com outros autores. De Tillich, tem por base conceitual de forma central o livro A Coragem de Ser, a partir do qual desenvolve uma antropologia desde os conceitos de angústia e coragem. O artigo investiga as tensões existenciais que moldam a experiência humana. Através de um diálogo entre Tillich e outros autores, examinamos a resistência do ser humano contra a coisificação, que ocorre quando o ser humano é reduzido a uma peça impessoal no mundo. A relação intrínseca entre o eu e o mundo é central na antropologia tillichiana, onde a formação da pessoa ocorre no encontro com outras pessoas, apontando para a importância da relacionalidade na construção da identidade humana. Ao analisarmos a coragem como resposta à ameaça do não-ser, seguindo a abordagem de Tillich, destacamos sua raiz teológica a partir da fé como aceitação existencial do incondicional. Essa afirmação da vida, contendo todas as suas ambiguidades, diante da ameaça do não-ser abre para uma verdadeira relacionalidade, ao fundamentar-se no Novo Ser. Concluímos evidenciando que a antropologia teológica não busca seguranças, mas se abre para a incerteza da vida concreta. Este estudo visa contribuir para a abordagem teológica das complexidades da condição humana, oferecendo uma análise crítica das dinâmicas contemporâneas e contribuindo para a compreensão mais profunda do ser humano e do significado da resposta de fé a partir da coragem e não do dogmatismo.
Evangelização na Amazônia
Authors: De Albuquerque Francisco Chagas
Published: May 2024

A inculturação do Evangelho foi uma das preocupações do Vaticano II. Em sua recepção, pela Igreja na América Latina, esta temática foi tomada a sério a partir da Conferência de Puebla (1979). Em sintonia com o magistério, desenvolvia-se, então, a nascente Teologia da Libertação, contribuindo para o processo de inculturação eclesial e do Evangelho. A Exortação Pós-sinodal Querida Amazônia (QAm) propõe uma evangelização radicalmente inculturada no território pan-amazônico. Na resposta a essa proposta, a teologia também deverá oferecer sua contribuição, como se tenta expor neste estudo.  Explicita-se o tema em quatro momentos: 1) magistério conciliar, culturas e teologia; 2) recepção do Concílio na A. Latina; 3) paradigma da inculturação do Evangelho na Igreja latino-americana; 4) linhas para a evangelização inculturada e teologia, seguidos de considerações sobre as possibilidades da reflexão teológica libertadora. Propõe-se que o quefazer teológico, na linha tradição teológica e eclesial latino-americana e do Caribe, requer conversão de seus autores(as), devendo-se superar o espírito colonialista, para dialogar com as culturas, espiritualidades e as tradições dos povos amazônicos.
Hermenêutica “Confessional” Protestante Luterana
Authors: Wachholz Wilhelm
Published: May 2024

A teologia protestante, e luterana em particular, deu novo impulso para a hermenêutica, resultando em reflexões importantes no campo da teologia, mas também de outras ciências. O objetivo deste artigo é apresentar reflexões da hermenêutica a partir da perspectiva protestante luterana por ocasião dos 200 anos de presença luterana permanente no Brasil (2024). Por “hermenêutica” entendemos a ciência que busca pela interpretação. Por “confessional” entendemos uma hermenêutica não limitada à recitação de verdades do passado – inclusive luteranas –, mas uma hermenêutica que precisa ter algo a “dizer”, a “confessar” para o nosso tempo, portanto, ser palavra “para nós”. Finalmente, por “protestante luterana” – e não Lutero! – entendemos não mera reprodução do pensamento de Lutero, mas a tradição teológica protestante oriunda e inspirada na teologia do reformador do século XVI, mas como um dizer e “confessar” face ao tempo e desafios atuais da humanidade.
Branquitude e privilégio branco na formação da Igreja Evangélica de Confissão Luterana no Brasil
Authors: Bayerl Padilha Günter , Bobsin Oneide
Published: May 2024

Este artigo discutirá as questões raciais e o privilégio branco como conceitos estruturantes da sociedade brasileira e suas implicações na formação da Igreja Evangélica de Confissão Luterana no Brasil tendo como base o referencial teórico-analítico de branquitude. Deste modo lançará luzes sobre os privilégios concedidos para as pessoas brancas ao longo do processo de formação da sociedade Brasileira, principalmente, após a Independência e Proclamação da República. Neste período as pessoas brancas eram tidas como sinal de desenvolvimento e as pessoas negras e indígenas eram consideradas como sendo as responsáveis pelo atraso do Brasil. Portanto, é neste cenário de privilégios para as pessoas brancas que as primeiras comunidades luteranas são fundadas e marcam a colonização da Região Sul e do Espírito Santo. Neste sentido, no Brasil, o luteranismo está marcado pelo pertencimento étnico e pela preservação da germanidade.  Portanto, o desafio para a Igreja Evangélica de Confissão Luterana no Brasil é tornar-se uma igreja pluriétnica, denunciar o racismo como pecado e iniciar um processo de luta antirracista para torna-se de fato uma Igreja no Brasil.
Monteiro Lobato e seis personagens em busca da nação
Authors: da Silva Santos Elisângela
Published: May 2024

Neste livro, Elisângela da Silva Santos investiga qual seria o “”pro­jeto”” de nação – compreendida como projeto político social – na obra destinada ao público infantil de Monteiro Lobato, conhecida também como uma literatura pedagógica. A autora acredita na pos­sibilidade de Lobato ser visto como integrante da galeria de nossos pensadores sociais, pois em seu gênero literário infantil ressoa uma visão de país, um diagnóstico e um projeto de futuro para o Brasil. Nesse sentido, a autora discute a possibilidade de tomar a litera­tura lobatiana como elemento de compreensão da realidade social brasileira dos anos 1920 e 1930. Assim, Elisângela Santos procura ver na obra de Lobato uma crítica à sociedade em que vivia o escritor que, além de estar preocupado com questões estéticas e linguísticas de seu tempo, sempre formulou críticas à nossa “”parasitia intelectual””, aos intelectuais e à elite que, segundo ele, assistia de braços cruza­dos aos diversos problemas de ordem social política e econômica, sem propor alternativas de mudanças.

Published: May 2024

Osteoarthritis (OA) is a degenerative disease with a high prevalence in the elderly population, but our understanding of its mechanisms remains incomplete. Analysis of serum exosomal small RNA sequencing data from clinical patients and gene expression data from OA patient serum and cartilage obtained from the GEO database revealed a common dysregulated miRNA, miR-199b-5p. In vitro cell experiments demonstrated that miR-199b-5p inhibits chondrocyte vitality and promotes extracellular matrix degradation. Conversely, inhibition of miR-199b-5p under inflammatory conditions exhibited protective effects against damage. Local viral injection of miR-199b-5p into mice induced a decrease in pain threshold and OA-like changes. In an OA model, inhibition of miR-199b-5p alleviated the pathological progression of OA. Furthermore, bioinformatics analysis and experimental validation identified Gcnt2 and Fzd6 as potential target genes of MiR-199b-5p. Thus, these results indicated that MiR-199b-5p/Gcnt2 and Fzd6 axis might be a novel therapeutic target for the treatment of OA.
Pilot study of the relation between various dynamics of avatar experience and perceptual characteristics

Published: May 2024

In recent years, due to the prevalence of virtual reality (VR) and human-computer interaction (HCI) research, along with the expectation that understanding the process of establishing sense of ownership, sense of agency, and limb heaviness (in this study, limb heaviness is replaced with comfort level) will contribute to the development of various medical rehabilitation, various studies have been actively conducted in these fields. Previous studies have indicated that each perceptual characteristics decrease in response to positive delay. However, it is still unclear how each perceptual characteristic changes in response to negative delay. Therefore, the purpose of this study was to deduce how changes occur in the perceptual characteristics when certain settings are manipulated using the avatar developed in this study. This study conducted experiments using an avatar system developed for this research that uses electromyography as the interface. Two separate experiments involved twelve participants: a preliminary experiment and a main experiment. As observed in the previous study, it was confirmed that each perceptual characteristics decreased for positive delay. In addition, the range of the preliminary experiment was insufficient for the purpose of this study, which was to confirm the perceptual characteristics for negative delay, thus confirming the validity of conducting this experiment. Meanwhile, the main experiment showed that the sense of ownership, sense of agency, and comfort level decreased gradually as delay time decreased, (i.e., this event is prior to action with intention, which could not be examined in the previous study). This suggests that control by the brain-machine interface is difficult to use when it is too fast. In addition, the distribution of the most strongly perceived settings in human perceptual characteristics was wider in regions with larger delays, suggesting this may lead to the evaluation of an internal model believed to exist in the human cerebellum. The avatar developed for this study may have the potential to create a new experimental paradigm for perceptual characteristics.
Exploring the influence of self-identification on perceptual judgments of physical and social causality
Authors: Vicovaro Michele , Squadrelli Saraceno Francesca , Dalmaso Mario
Published: May 2024

People tend to overestimate the causal contribution of the self to the observed outcome in various situations, a cognitive bias known as the ‘illusion of control.’ This study delves into whether this cognitive bias impacts causality judgments in animations depicting physical and social causal interactions. In two experiments, participants were instructed to associate themselves and a hypothetical stranger identity with two geometrical shapes (a circle and a square). Subsequently, they viewed animations portraying these shapes assuming the roles of agent and patient in causal interactions. Within one block, the shape related to the self served as the agent, while the shape associated with the stranger played the role of the patient. Conversely, in the other block, the identity-role association was reversed. We posited that the perception of the self as a causal agent might influence explicit judgments of physical and social causality. Experiment 1 demonstrated that physical causality ratings were solely shaped by kinematic cues. In Experiment 2, emphasising social causality, the dominance of kinematic parameters was confirmed. Therefore, contrary to the hypothesis anticipating diminished causality ratings with specific identity-role associations, results indicated negligible impact of our manipulation. The study contributes to understanding the interplay between kinematic and non-kinematic cues in human causal reasoning. It suggests that explicit judgments of causality in simple animations primarily rely on low-level kinematic cues, with the cognitive bias of overestimating the self’s contribution playing a negligible role.

Published: May 2024

A área de Ciências Ambientais busca compreender interações entre sistemas antrópicos e naturais. Na pesquisa, possibilita promissoras expectativas para a formação socioambiental orientada por metodologias interdisciplinares. Nas políticas públicas, proporciona garantia de direitos e ressignificação de teias de relações socioecossistêmicas, quando a educação ambiental é traduzida para a sensibilização/conscientização de problemáticas socioambientais emergentes. Objetivou-se analisar temáticas abordadas em seminários sobre tópicos de políticas públicas ambientais, fazendo associações com a educação ambiental. Foi realizada pesquisa-participante no componente curricular Tópicos de Políticas Públicas – Níveis Mestrado e Doutorado – da Universidade Federal do Piauí, em 2021.1. Houve participação em nove seminários em Ciências Ambientais e elaboração de papers (miniartigos científicos) correspondentes. Os papers foram descritos, dialogados com literatura específica e tiveram como temas principais em Ciências Ambientais abordados Sustentabilidade (Papers 1, 2, 3, 5), Políticas públicas ambientais (Papers 3, 4, 6 e 7), Gestão ambiental (Paper 8) e Desenvolvimento sustentável (Papers 1 e 9), por vezes, intersecionados, como nos papers 1 (Sustentabilidade e Desenvolvimento sustentável) e 3 (Políticas públicas ambientais e Sustentabilidade). Ao fazer associações com educação ambiental, indica-se abordagens multidisciplinares com perspectivas pensadas para a ação-reflexão-crítica e políticas públicas racionais sobre problemas socioambientais. A interdisciplinaridade se faz necessária na abordagem em Ciências Ambientais. No contexto das políticas públicas na pós-graduação, possibilita diálogos, exposições e argumentações sobre ambiguidades e polissemias de assuntos que abrangem conscientização socioambiental.
The Motif of Worship, Prayer, and Prophecy in Luke 1:5–25 as a Bridge between the Old Testament and the Gospel of Luke
Authors: Aryeh Daniel Nii Aboagye
Published: May 2024

This article provides an exegetical contribution to the proposition by David E. Garland that the Old Testament period of the promise found fulfilment in the New Testament. The specific contribution of this study is the elements/traces of a bridge between the Old Testament and the annunciation/nativity narrative of Luke 1:5-25. The Gospel of Luke is characterised by people worshipping, praying, and fulfilling prophecy, as evidenced in the first two chapters of the book. There have been studies on the nativity narrative of the Gospel of Luke which usually took a historical comparative approach between the birth narrative of Jesus and that of John, and investigations into the uniqueness of the story to Luke. It leaves out the thematic discussion of some ethoses of the annunciation narrative that seeks to provide an unflinching link to the Old Testament. This article examines worship, prayer, and prophecy in the annunciation and nativity narrative in Luke 1:5-25 to draw possible relationships to the Old Testament. The diachronic narrative-semantic method is used for the study. The findings are that the narrative alludes to Old Testament stories of worship, prayer, and fulfilment of prophecy and suggests a link or bridge between the Old and New Testaments. Keywords: John the Baptist, Fulfilment, Prayer, Prophecy, Luke 1:5–25, Worship

The present study is mainly about the comparative analysis of marketing efficiency of cut roses under organised and unorganised markets. For the present study, the primary data was collected from the Krishna Raja Market, Bengaluru an unorganised market, whereas the International Flower Auction Centre, Bengaluru (IFAB) is an organised market. Data collected from 40 market intermediaries in each market structure and total intermediaries were to be 80. Forty rose vendors are randomly selected to gather marketing constraints in organised market. In the study area, three major marketing channels were observed for cut rose marketing in unorganised market structure: Channel I: Producer – Wholesaler – Retailer – Consumer; Channel II: Producer – Retailer – Consumer; and Channel III: Producer– Commission agent– Retailer – Consumer, whereas in the organised market, two marketing channels were prominent, i.e., Channel I: Producer – IFAB – Wholesaler – Retailer – Consumer and Channel II: Producer – IFAB – Retailer – Consumer. Marketing efficiency was estimated using the Acharya and Agarwal methodology. In this analysis, direct marketing channel was found to be the most efficient for unorganised and organised markets. Marketing constraints were analysed using Rank Based Quotient (RBQ) technique. Quality standards and the lack of price information were the most important problems for the farmers while marketing the flowers in organised markets rather than unorganised markets. Hence, policymakers should provide producers with the required facilities and impart proper knowledge about quality standards to farmers, leading to more income for producers.

Authors: Igwegbe K.C. , Onwukeme V.I. , Okeke A.P.
Published: May 2024

The study evaluated the organochlorine pesticide residue levels in fruits and vegetables sold in Federal Capital Territory, Abuja. Six samples were bought from eleven major markets across the six Area Councils of FCT, Abuja. The samples were mixed to form composite groups of the fruits and vegetables, and prepared using QuEChERS method. It was analysed using Agilent 7890 Gas Chromatography equipped with a micro-cell Electron Capture Detector (μECD). The analysis revealed that the hazard index (HI) for all the fruits and vegetables studied were well below the levels of adverse health effect for chronic exposure except for Onion in children which was 1.2287. The HI for the various fruits and vegetables in children were higher than those for the adult. For example, the HI for Tomato, Green Amaranth Leaves and Pepper all in children were 0.4485, 0.4411 and 0.3981 respectively while the HI for Tomato, Green Amaranth Leaves and Pepper all in adult were 0.1121, 0.1103 and 0.0995 respectively. The calculated cancer risk associated with the consumption of these fruits and vegetable showed values well below the upper bound of 1.0x10-6 except for Aldrin, Dieldrin, Heptachlor, Heptachlor Epoxide. a-BHC, b-BHC, and d-BHC especially in children. From the hazard index and cancer risk analysis, Aldrin and Dieldrin have been implicated as the pesticides of concern since they were present in reasonable concentrations for almost all the samples and age groups studied. The highest potential of cancer risk was found in Onions for children. Also, the total cancer risk implicated Onions (with a value of 1.2x10-4 for adult and 4.7x10-4 for children) and Pepper (with a value of 5.5x10-5 for adult and 2.2x10-4 for children) as the most contaminated foodstuffs with pesticide residues in the studied area. The order of the total cancer risk from the study was Onions > Pepper > Tomato > Green Amaranth Leaves > Fluted Pumpkin Leaves > Okra for both adult and children. In conclusion it was observed that pesticide residues of Endrin, o,p'-DDE and Heptachlor in Onions, Green Amaranth Leaves and Pepper were above the Codex maximum residue level (MRL). Endrin in Onions had 858.0%, o, p'-DDE in Onions had 276.0%, o, p'-DDE in Green Amaranth Leaves had 100.8%, Heptachlor in Pepper had 168.4% and Heptachlor in Onions had 119.2%. Also, the hazard index of chronic exposure and cancer risk of children for Onions requires urgent attention as their values were well above the acceptable limit. Therefore, periodic monitoring of pesticides residues in these fruits and vegetables cannot be over emphasized, but will go a long way to prevent, control and reduce environmental pollution and health risks. Also, taking precautionary measures like proper cooking before consumption of these foodstuffs is advised.

Paper products have been used for thousands of years for art and communication purposes.
The presented project describes the development of a unique greeting card art paper product, comprised of a card stock with a basis weight of 150 g/m2 having a purple color tone and inlay paper product with a basis weight of 100 g/m2. The inlay paper product should have a gras fiber content that is visualized by a tree cut out in the cover paper.
The inlay paper should be printable with a standard ink-jet printer as well as be able to write on with a fountain pen.
Both paper grades were developed with a hand sheet study and then upscaled to a small 225 mm wide laboratory Fourdrinier paper machine. The produced cover paper and inlay paper had a basis weight of 152.20 g/m2 for the cover paper having a purple color tone and 102.64 g/m2 for the inlay paper, meeting all mechanical and optical properties as required.
The finished cover and inlay paper product was converted into DIN A5 and DIN A6 card stock, including cutting out the tree image from the cover paper using a laser cutter.

Objetivo: compreender o significado da maternidade e da maternagem em mulheres que usam cadeiras de rodas. Métood: investigação qualitativa envolvendo seis mulheres cadeirantes. Coletaram-se os dados por meio de entrevistas semiestruturadas, submetidas a análise temática de conteúdo. Resultados: o significado da maternidade envolve sentimentos positivos e alguns negativos como "medo",“ansiedade” e ainda atributos como "sonho" e “maravilhoso”. No tocante à maternagem as participantes entendem que elas são responsáveis pelos cuidados nos primeiros tempos de vida do bebê, e que ao longo desse processo surgem dificuldades, todavia percebem que os resultados e benefícios encontrados são muito mais relevantes. Conclusão: compreende-se que o significado da maternidade e da maternagem em mulheres cadeirantes é permeado por sentimentos ambivalentes e concomitantes, os quais foram reformados com aspectos de superação e autoestima, sobretudo aos esteriótipos negativos traçados socialmente e culturalmente.
Overview of Receptor Allosterism
Authors: Gregory Karen J. , Sexton Patrick M. , Christopoulos Arthur
Published: December 2010

In addition to the orthosteric site, which recognizes endogenous ligands, most G protein–coupled receptors (GPCRs) possess topographically distinct allosteric sites that can be recognized by small molecules and accessory cellular proteins. Ligand binding to allosteric sites promotes a conformational change in the GPCR that can alter orthosteric ligand affinity and/or efficacy. Moreover, there has been an increase in recent years in the identification of allosteric agonists that can directly activate the receptor in the absence of orthosteric ligand. Allosteric sites are attractive therapeutic targets because they can be exploited to achieve modes of selectivity and signaling that are not attainable by orthosteric means. However, an important challenge in this field remains the quantification of the myriad of possible allosteric effects on binding and signaling events. This unit provides an overview on GPCR allosterism and the different pharmacological approaches to understanding allosteric behaviors.Curr. Protoc.

Craniofacial ciliopathies: A new classification for craniofacial disorders
Authors: Brugmann Samantha A. , Cordero Dwight R. , Helms Jill A.
Published: December 2010

Craniofacial anomalies are some of the most variable and common defects affecting the population. Herein, we examine a group of craniofacial disorders that are the result of defects in primary cilia; ubiquitous, microtubule‐based organelles that transduce molecular signals and facilitate the interactions between the cell and its environment. Based on the frequent appearance of craniofacial phenotypes in diseases born from defective primary cilia (ciliopathies) we propose a new class of craniofacial disorders referred to as craniofacial ciliopathies. We explore the most frequent phenotypes associated with ciliopathic conditions and the ciliary gene mutations responsible for craniofacial defects. Finally, we propose that some non‐classified disorders may now be classified as craniofacial ciliopathies. © 2010 Wiley‐Liss, Inc.
Molecular characterization of a novel, de novo, cryptic interstitial deletion on 19p13.3 in a child with a cutis aplasia and multiple congenital anomalies

Published: December 2010

We report on a de novo constitutional deletion within G‐band region 19p13.3 in a girl with cutis aplasia of the scalp, facial anomalies, structural heart abnormalities, hypotonia, mild mental retardation and conductive hearing loss which we characterized with chromosomal microarray, fluorescence in situ hybridization (FISH), and SNP analyses. Initial microarray analysis revealed a 6‐BAC‐clone deletion covering an approximately 1.612 Mb region within 19p13.3. Subsequent BAC FISH studies delineated the proximal deletion breakpoint to within BAC clone RP11‐125C3 and the distal deletion breakpoint to within BAC clone RP11‐648B14. SNP analysis showed the deletion to be of paternal origin and further refined its distal breakpoint to within a 20 kb region between rs11666694 and novel SNP2 that we identified at g.2,924,845, and its proximal deletion breakpoint to within a 22 kb region between rs35280644 and rs262562. Accordingly, the size of the deletion was revised to 1.89–1.932 Mb in length. We identified many Alu, L1, and L2 repeats, as well as SINE and LINE sequences at both deletion breakpoints. We found the deletion to encompass 71 genes, two of which appear to be good candidates for the patient's observed craniofacial and cardiac anomalies: guanine nucleotide binding protein (G protein), alpha 11 (Gq class)(GNA11), and Transducin‐like Enhancer of Split 2 (E(sp1) homolog, Drosophila)(TLE2). © 2010 Wiley‐Liss, Inc.
An investigation into the influence of electrospinning parameters on the diameter and alignment of poly(hydroxybutyrate‐co‐hydroxyvalerate) fibers
Authors: Tong Ho‐Wang , Wang Min
Published: December 2010

Electrospinning is an effective technology for the fabrication of ultrafine fibers, which can be the basic component of a tissue engineering scaffold. In tissue engineering, because cells seeded on fibrous scaffolds with varying fiber diameters and morphologies exhibit different responses, it is critical to control these characteristics of electrospun fibers. The diameter and morphology of electrospun fibers can be influenced by many processing parameters (e.g., electrospinning voltage, needle inner diameter, solution feeding rate, rotational speed of the fiber‐collecting cylinder, and working distance) and solution properties (polymer solution concentration and conductivity). In this study, a factorial design approach was used to systematically investigate the degree of influence of each of these parameters on fiber diameter, degree of fiber alignment, and their possible synergetic effects, using a natural biodegradable polymer, poly(hydroxybutyrate‐co‐hydroxyvalerate), for the electrospinning experiments. It was found that the solution concentration invoked the highest main effect on fiber diameter, whereas both rotational speed of the fiber‐collecting cylinder and addition of a conductivity‐enhancing salt could significantly affect the degree of fiber alignment. By carefully controlling the electrospinning parameters and solution properties, fibrous scaffolds of desired characteristics could be made to meet the requirements of different tissue engineering applications. © 2010 Wiley Periodicals, Inc.

A study on compatibility of polymer blends of polystyrene/poly(4‐vinylpyridine)
Authors: Parashar Pratima , Ramakrishna K. , Ramaprasad A. T.
Published: December 2010

Blends of polystyrene/poly (4‐vinylpyridine) have been prepared by casting from a common solvent. The compatibility of the blends was studied by using dilute solution viscometry (DSV), differential scanning calorimetery (DSC), Fourier transformation‐infrared spectroscopy (FT‐IR), and scanning electron microscopy (SEM). The relative viscosity versus composition plots for the blends are not perfect linear. The corresponding intrinsic viscosity values show negative deviation from ideal behavior when plotted against composition. Also, the modified Krigbaum and Wall interaction parameter, Δb, shows small and negative values for all compositions except for the blend PS/P4VP (25 : 75). The results indicate that the polymers are incompatible but small interaction values predict physically miscible blends which eventually show phase separation, as is observed in the present studies. However, the blends as obtained show a single, composition‐dependent, glass transition temperature that fits the Fox equation well, indicating the presence of homogeneous phase. The constant, k obtained from Gordon‐Taylor equation suggests intermolecular attraction between these polymers. FT‐IR and SEM support the results of DSV and DSC. © 2010 Wiley Periodicals, Inc.

Published: December 2010

The extraction conditions of intracellular polysaccharide fromCordyceps militarisSU‐08 mycelia in submerged culture were investigated. Four parameters affecting the IPS extraction were determined by Plackett‐Burman (PB) tests and then optimized by response surface methodology (RSM). The optimum conditions of IPS extraction were predicted to be, ultrasonic treatment number 61.45, ultrasonic power 543.64 W, ethanol multiple 3.28, and extraction temperature 82.61°C, and the extraction rate of IPS was estimated at 9.11%. The actual value of IPS under these conditions was 9.19%. Thein vitroantioxidant results showed that the inhibition effects of IPS at a dosage of 5 g L−1on hydroxyl, superoxide anion, and 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) radical were 51.89% ± 3.27%, 82.26% ± 5.03%, and 74.59% ± 4.53%, respectively, which were 32.98% ± 2.71%, 69.71% ± 4.24%, and 41.64% ± 3.28% higher than that of control, respectively. The reducing power of IPS was 0.79 ± 0.03 (absorbance at 700 nm), 11.27% ± 0.82% higher than that of control. The results provide a reference for large‐scale extraction of IPS byC. militarisSU‐08 in industrial fermentation and the IPS can be used as a potential antioxidant which enhances adaptive immune responses. © 2010 Wiley Periodicals, Inc.
