Expectations Of Orthodontic Treatment In Adults: The Conduct In Orthodontist/patient Relationship.

The high demand for orthodontic treatment, evidenced over the last few decades, has been justified mainly by the greater importance given to facial esthetics, influencing individual's self esteem. However, the professional frequently does not meet all the patient's expectations, for not establishing good communication and not knowing about the critical points during orthodontic treatment. The aim of this study was to elucidate patients' desires and doubts regarding orthodontic treatment, by means of a survey applied to 60 adult patients. The analysis of results revealed that most individuals (38.3%) noticed treatment success after its conclusion. Occlusion deviation was pointed out by 66.7% as the main reason for seeking treatment, and esthetics ranked as second (with 48.3%). Treatment time was considered within the prediction by 46.7% of the interviewees and the results were judged as very good by 43.3%. The social relations of most participants were not affected by treatment (73.3%). Also, 58.3% of the interviewees reported pain as the main complaint and 53.3% found it difficult to use dental floss. Most participants saw the orthodontist as a professional who was concerned about their health (76.7%), and believed that he/she was more able to treat them (96.6%) when compared with the general practitioner. The orthodontist/patient relationship enables an understanding of the expectations regarding orthodontic treatment, resulting in greater motivation and cooperation, leading to a successful outcome.1888-9

The low oxygen consumption is reflected on depression scores in elderly

The study aimed to investigate the effects of different types of exercise in indicative scores of depression in the elderly. Participated 168 elderly volunteers of both sexes, aged 60-75 years (65.66 ± 4.28 years), 40 women and 128 men. The volunteers were divided into seven distinct groups: a) Sedentary control (n = 40); b) Resisted control (n = 23); c) Walking (n = 23); d) Outdoor (n = 20); e) Cycle ergometer (n = 23); f) Resisted 50% of 1RM (n = 19); and g) Resisted 80% of 1RM (n = 20), and subjected to a protocol of six months of physical training three times a week. The group a remained without changing their routine activities during the study period and did not engage in any exercise program, as the group b appeared in the laboratory, but performed the exercises without charge. Before and immediately after the study period, the volunteers underwent an evaluation protocol for determination of oxygen consumption and responded to the Geriatric Depression Scale. The results revealed that the groups c and e, who exercised at intensities with predominant aerobic metabolism, showed reduction in depression scores, and other measures were not sufficient to promote reduction in this variable. The data suggest that exercise dominance in aerobic metabolism is more effective in reducing depression scores in elderly.O objetivo do estudo foi investigar os efeitos de diferentes tipos de exercício físico nos escores indicativos de depressão em idosos. Participaram 168 voluntários idosos, de ambos os sexos, com idades de 60 a 75 anos (65,66±4,28 anos), sendo 40 mulheres e 128 homens. Os voluntários foram alocados em sete grupos distintos: a) Controle sedentário (n=40); b) Controle resistido (n=23); c) Caminhada (n=23); d) Lazer (n= 20); e) Cicloergômetro (n=23); f) Resistido 50% de 1RM (n=19); e g) Resistido 80% de 1RM (n=20), sendo submetidos a um protocolo de seis meses de treinamento físico, três vezes por semana. O grupo a permaneceu sem alterar suas atividades de rotina durante o período de estudo e não se engajou em nenhum programa de exercício físico, já o grupo b compareceu no laboratório, mas realizou os exercícios sem carga. Antes e imediatamente após o período de estudo, os voluntários foram submetidos a um protocolo de avaliação para determinação do consumo de oxigênio e responderam à Escala Geriátrica de Depressão. Os resultados revelaram que os grupos c e e, que se exercitaram em intensidades com predomínio do metabolismo aeróbio, apresentaram redução nos escores de depressão, sendo que as demais intervenções não foram suficientes para promover redução nessa variável. Os dados sugerem que exercícios com predominância no metabolismo aeróbio são mais efetivos em promover reduções em escores de depressão de idosos.Centro de Estudos em Psicobiologia e ExercícioUniversidade Federal de São Paulo (UNIFESP) Departamento de BiociênciasUniversidade Federal do ABC Centro de Matemática, Computação e CogniçãoUniversidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de PsicobiologiaUNIFESP, Depto. de BiociênciasUNIFESP, EPM, Depto. de PsicobiologiaSciEL

Phellem cell-wall components are discriminants of cork quality in Quercus suber

Original ResearchCork is a renewable, non-wood high valued forest product, with relevant ecological and economic impact in the Mediterranean-type ecosystems. Currently, cork is ranked according to its commercial quality. The most valuable planks are chosen for cork stoppers production. Cork planks with adequate thickness and porosity are classified as stoppable quality cork (SQC). The chemical composition of cork is known, but the regulation of metabolic pathways responsible of cork production and composition, hence of cork quality, is largely unknown. Here, we tested the hypothesis that post-genomic events may be responsible for the development of SQC and N-SQC (non-stoppable quality cork). Here, we show that combined proteomics and targeted metabolomics (namely soluble and cell wall bound phenolics) analyzed on recently formed phellem allows discriminate cork planks of different quality. Phellem cells of SQC and N-SQC displayed different reducing capacity, with consequential impact on both enzymatic pathways (e.g., glycolysis) and other cellular functions, including cell wall assembly and suberization. Glycolysis and respiration related proteins were abundant in both cork quality groups, whereas the level of several proteins associated to mitochondrial metabolism was higher in N-SQC. The soluble and cell wall-bound phenolics in recently formed phellem clearly discriminated SQC from N-SCQ. In our study, SQC was characterized by a high incorporation of aromatic components of the phenylpropanoid pathway in the cell wall, together with a lower content of hydrolysable tannins. Here, we propose that the level of hydrolysable tannins may represent a valuable diagnostic tool for screening recently formed phellem, and used as a proxy for the quality grade of cork plank produced by each treeinfo:eu-repo/semantics/publishedVersio

Development of a manometric monitoring method for early detection of air microbiological contamination in the bloodstream

Atmospheric air is a microbial habitat of pathogenic bioaerosols that may pose serious risks to humans. A commonly laboratory-based approach for the diagnosis of such infections in the bloodstream is the blood culture analysis. Its clinical relevance is attributed to the fact that these infections are characterized by high rates of morbidity and mortality, requiring the need for efficient methods for rapid diagnosis. For this reason, our study aimed to develop a method of manometric monitoring for the rapid detection of viable microorganisms in blood culture vials. A methodology was developed to detect pressure variation in intra-vials through a manometric instrument that was coupled to vials of blood culture containing culture broth that allowed microbial growth. This device allowed the early detection of microbial activity based on the production or use of intra-flask gases as a result of microbial metabolic activity. The analyzed variables were the pressure as a function of time, microbial species, and culture medium. The highest pressure found in the flasks without microorganisms was 40 mmHg between 2 and 6 h, and the lowest pressure was 42 mmHg between 21 and 24 h. The variation of the internal pressure in blood culture flasks according to different groups of microorganisms as a function of time demonstrated that the fermentative gram-negative bacilli and gram-positive cocci exhibited a significant increase in relation to their respective control groups (p < 0.001). The non-fermenting gram-negative bacilli showed expected results in relation to the pressure variation in which the production of negative pressures was noticed during the period of analysis, with a significant difference with respect to their control groups (p < 0.001). The developed methodology for the early detection of microorganisms responsible for bloodstream infection was demonstrated to be effective.e Fundação de Apoio à Pesquisa e à Inovação Tecnológica do Estado de Sergipe-Program Centelha (FAPITEC/SE) and by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), and Portuguese Science and Technology Foundation (FCT) through the project UIDB/04469/2020 (strategic fund) funded by national funds, and co-financed Education (FCT/MEC) from national funds and FEDER, under the Partnership Agreement PT2020info:eu-repo/semantics/publishedVersio

Red propolis and its dyslipidemic regulator formononetin: evaluation of antioxidant activity and gastroprotective effects in rat model of gastric ulcer

Propolis has various pharmacological properties of clinical interest, and is also considered a functional food. In particular, hydroalcoholic extracts of red propolis (HERP), together with its isoflavonoid formononetin, have recognized antioxidant and anti-inflammatory properties, with known added value against dyslipidemia. In this study, we report the gastroprotective effects of HERP (50–500 mg/kg, p.o.) and formononetin (10 mg/kg, p.o.) in ethanol and non-steroidal anti-inflammatory drug-induced models of rat ulcer. The volume, pH, and total acidity were the evaluated gastric secretion parameters using the pylorus ligature model, together with the assessment of gastric mucus contents. The anti-Helicobacter pylori activities of HERP were evaluated using the agar-well diffusion method. In our experiments, HERP (250 and 500 mg/kg) and formononetin (10 mg/kg) reduced (p < 0.001) total lesion areas in the ethanol-induced rat ulcer model, and reduced (p < 0.05) ulcer indices in the indomethacin-induced rat ulcer model. Administration of HERP and formononetin to pylorus ligature models significantly decreased (p < 0.01) gastric secretion volumes and increased (p < 0.05) mucus production. We have also shown the antioxidant and anti-Helicobacter pylori activities of HERP. The obtained results indicate that HERP and formononetin are gastroprotective in acute ulcer models, suggesting a prominent role of formononetin in the effects of HERP.This work has been funded by the Fundação de ApoioàPesquisa eàInovação Tecnológica do Estadode Sergipe (FAPITEC/SE), by the Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq).R.L.C.d.A.-J., S.M.T., and J.C.C. received CNPq productivity grants.

Microcolony detection of Mycobacterium Bovis in Middlebrook 7H11 thin layer culture

The aim of this article is to evaluate the efficiency of the cultivation technique in thin layer of Middlebrook 7H11 (TL7H11) for isolating Mycobactererium bovis from suggestive lesions of tuberculosis in cattle and to compare the results with traditional methods of cultivation. At the first step it was used M. bovis AN5 and M. tubercuolosis H37Rv standard strain. The both performance were compared between the cultivation in TL7H11 and in the Stonebrink and Petragnani media. The strains presented visible growing in TL7H11 at the third day of cultivation, while the Stonebrink and Petragnani there were growing just at the 14 day. At the 13 day of cultivation it was possible to differentiate both strains by their colony morphological characteristics. The second step was to cultivate 62 clinicals samples in TL7H11 and Stonebrink for tentative isolation of M. bovis. The isolated samples were detected in TL7H11 until 21 days of cultivation whereas none samples weregrown in Stonebrink tubes. The median time of growing in TL7H11 was 19,0 days against 49,0 days of Stonebrink (p=0,014).O presente trabalho teve por objetivo avaliar a eficiência da técnica de cultivo em camada delgada de ágar Middlebrook 7H11 (TL7H11) no isolamento de Mycobacterium bovis de lesões sugestivas de tuberculose em bovinos, comparando seus resultados com os métodos tradicionais de cultivo. Numa primeira fase foram utilizadas estirpes padrão de M. bovis AN5 e M. tuberculosis H37Rv mantidas em laboratório, para comparação de desempenho entre o cultivo em TL7H11 e nos meios de Stonebrik e Petragnani. Ambas estirpes apresentaram crescimento visível em TL7H11 no terceiro dia de cultivo enquanto que nos meios de Stonebrink e Petragnani só houve crescimento a partir do 14º dia. Aos 13 dias de cultivo em TL7H11 foi possível diferenciar as duas estirpes pelas características morfológicas das colônias. Numa segunda fase, 62 amostras de campo foram cultivadas em TL7H11 e Stonebrink para isolamento de M. bovis. As amostras isoladas foram detectadas pelo TL7H11 até os 21 dias de cultivo contra nenhum crescimento dos tubos de Stonebrink. O tempo médio de crescimento no TL7H11 foi de 19,0 dias contra 49,0 dias do meio de Stonebrink (p = 0,014)
