Necessidade de implementação dos instrumentos financeiros bilhetes de tesouro e certificado depósito do BCSTP

O sistema financeiro santomense é relativamente jovem e vem se desenvolvendo paulatinamente, após a reforma e liberalização em 1992, assente num sistema bancário a dois níveis, com predominância dos bancos comerciais (8 bancos em Dezembro de 2014) e supervisionado pelo Banco Central de São Tomé e Príncipe. Este trabalho visa analisar a necessidade de implementação de Bilhetes do Tesouro (BT) e Certificados de Depósito do Banco Central (CDBC) em São Tomé e Príncipe para a dinamização do sistema financeiro. Para tal desenvolveu-se um estudo descritivo e exploratório sobre o sistema financeiro santomense e das condições macroeconómicas do país. Consultou-se ainda as administrações dos bancos comerciais a operar no país sobre a eventual adesão a estes produtos e sua percepção quanto à utilidade para o sistema, aplicando-se uma entrevista por questionário aos 8 administradores. Mais de 50% dos inquiridos foram de opinião que esses dois instrumentos seriam um bom meio de investimento e a sua implementação seria excelente para os mesmos. Mais de 60% responderam que utilizariam estes instrumentos como colateral nas transacções do mercado monetário interbancário, com preferência para os CDBC. Deste modo concluiu-se que o mercado estará receptivo para estes produtos e que estes serão necessários para a dinamização do mercado monetário, perspectivando-se o seu contributo positivo para o desenvolvimento económico do país, para a eficiência e liquidez do mercado financeiro santomense.info:eu-repo/semantics/publishedVersio

Caries prevalence and risk factors among children aged 0 to 36 months

O objetivo deste trabalho foi avaliar a prevalência de cárie e de fatores de risco em crianças com idade até 36 meses cadastradas no Ambulatório de Pediatria do Hospital Universitário Pedro Ernesto (HUPE-UERJ). Após a obtenção de consentimento livre e informado, foi realizada uma entrevista com os responsáveis por meio da qual foram avaliados os fatores de risco à cárie, incluindo condições sócio-econômico-culturais, hábitos de higiene oral e de dieta. Um único examinador realizou o exame bucal das crianças para a avaliação de cárie, de biofilme dental e de sangramento gengival. Os dados obtidos foram analisados através do programa Epi Info, utilizando-se o teste qui-quadrado. As crianças tinham em média 22,9 meses de idade. A prevalência de cárie encontrada, incluindo lesões não cavitadas, foi de 41,6% e o índice ceo-s foi de 1,7 (± 2,5). Os dentes mais afetados foram os anteriores superiores e o tipo de lesão mais comum foi a mancha branca ativa. Não houve associação significativa estatisticamente entre a prevalência de cárie e os fatores sócio-econômico-culturais, freqüência de higiene, hábito de amamentação noturna e dieta cariogênica durante o dia. Entretanto, a associação entre cárie e presença de biofilme dental foi considerada altamente significativa (p < 0,001). Os resultados sugerem que o acúmulo de biofilme dental espesso foi o fator preponderante para a ocorrência da cárie de estabelecimento precoce na amostra avaliada.The aim of this study was to assess the prevalence of caries and risk factors in outpatients of the Pediatric Ambulatory of the Pedro Ernesto University Hospital aging up to 36 months. After signing informed consent forms, the parents answered a structured questionnaire in order to evaluate risk factors for dental caries, including socioeconomic status, oral hygiene and dietary habits. A single investigator carried out the dental examination which assessed the presence of caries, biofilm and gingival bleeding. The data were analyzed by means of the Epi Info program, utilizing the chi-squared test. The childrens mean age was 22.9 months. The prevalence of caries, including white spot lesions, was 41.6%, and the mean def-s was 1.7 (± 2.5). The most affected teeth were the maxillary incisors, and the most common lesion was the white spot. No significant associations were found between the prevalence of caries and socioeconomic status, frequency of oral hygiene, nocturnal bottle- and breast-feeding or cariogenic food and beverage intake during the day. However, the association between caries and oral hygiene quality (dental biofilm) was statistically significant (p < 0.001). The results suggest that the presence of a thick biofilm was the most important factor for the occurrence of early childhood caries in the evaluated sample

Positive Effects of Extra-Virgin Olive Oil Supplementation and DietBra on Inflammation and Glycemic Profiles in Adults With Type 2 Diabetes and Class II/III Obesity: A Randomized Clinical Trial

Background: Evidence on the effects of dietary interventions on inflammatory markers in individuals with obesity and type 2 diabetes mellitus (T2DM) is scarce. Our study evaluated the effects of extra-virgin olive oil alone and in combination with a traditional Brazilian diet on inflammatory markers and glycemic profiles in adults with both T2DM and class II/III obesity. Methods: Adults aged 18-64 years with T2DM and class II/III obesity were randomized into two intervention groups: 1) extra-virgin olive oil only and 2) extra-virgin olive oil + a traditional Brazilian diet (OliveOil+DietBra). Data on sociodemographic characteristics, lifestyle, anthropometry, biochemical markers and inflammatory markers were collected. The primary outcomes were glycemic parameters and inflammatory markers. The body mass index (BMI) and weight were the secondary outcomes. Results: Forty individuals with T2DM and class II/III obesity were enrolled, and 34 (85%) completed the intervention course. The intake of olive oil was 37.88 ± 12.50 mL/day in the olive oil group and 37.71 ± 12.23 mL/day in the OliveOil+DietBra group, with no significant difference between groups (p = 0.484). Compared to the olive oil only group, the OliveOil+DietBra group had significantly lower levels of fasting insulin (p = 0.047) at the end of the intervention, whereas the other glycemic parameters were not altered. In the OliveOil+DietBra group, serum levels of inflammatory cytokines, IL-1α (p = 0.006) and adiponectin (p = 0.049) were lower and those of TNFα were higher (p = 0.037). There was a significant reduction in BMI and weight compared to the baseline values in the OliveOil+DietBra group (p = 0.015). Conclusions: The intervention with OliveOil+DietBra effectively decreased the levels of fasting insulin, IL-1α and adiponectin, suggesting its beneficial role in improving the inflammatory profiles and fasting insulin levels in adults with class II/III obesity and T2DM.

Soil preparation and NPK fertilization in the planting of five Atlantic Rainforest species in a clay extraction area

The occurrence of degraded areas worldwide grows each year and measures must be taken to mitigate degradation and to recover these areas. The aim of this study was to assess the effect of soil preparation and NPK levels on the growth of five native species of the Atlantic Rainforest in clay extraction area. The experimental design was randomized block in a split-split plot arrangement with four replications. Subsoiling and scarification soil preparation represented main plots.  Doses of NPK 04-14-08: 0; 40; 80;160; and 320 g pit-1 represented subplots and Atlantic Rainforest native species represented sub-subplots. Absolute growth rate, stem diameter and number of leaves were evaluated, 210 days after planting. The type of soil preparation did not influence the development of the species. The best dose for Dalbergia ecastaphyllum, Inga laurina, Protium heptaphyllum and Psidium cattleyanum were 176.49, 150.18, 199.25 and 166.48 g pit-1 of NPK, respectively. Schinus terebinthifolius was highly responsive to planting fertilization, being recommended 320 g pit-1 of NPK. All species are indicated for area recovery.The occurrence of degraded areas worldwide grows each year and measures must be taken to mitigate degradation and to recover these areas.

Impact of soil moisture on crop yields over Brazilian semiarid

The objective of this work was to investigate the relationship between soil water content and rainfall with rice, beans, cassava and corn yields in the semiarid region of Northeast Brazil. Precipitation and modeled soil water content were compared to yields recorded at the county levels in this region. The results were also integrated over the area of the nine States that lie within the officially recognized region of semiarid climate in Brazil. The influence of water balance components was quantified by calculating their correlation coefficient with yields of the different crop species over the municipalities of the region. It was found that rainfall had higher correlation to crop yields over most of the region, while soil water content had lower values of correlation. This result is consistent with the fact that average root depth is 40 cm, lower than the layer of soil used in the model used to estimate soil water content (100 cm). Plants respond better to the precipitation in the top layers of soil, while the water storage in the deep layer of soil might be important only in other temporal and spatial scales of the hydrological cycle.Peer ReviewedPostprint (published version

Cytotoxicity of glass ionomer cements containing silver nanoparticles

Background: Some studies have investigated the possibility of incorporating silver nanoparticles (NAg) into dental materials to improve their antibacterial properties. However, the potential toxic effect of this material on pulp cells should be investigated in order to avoid additional damage to the pulp tissue. This study evaluated the cytotoxicity of conventional and resin-modified glass ionomer cements (GIC) with and without addition of NAg. Material and Methods: NAg were added to the materials at two different concentrations by weight: 0.1% and 0.2%. Specimens with standardized dimensions were prepared, immersed in 400 μL of culture medium and incubated at 37°C and 5% CO2 for 48 h to prepare GIC liquid extracts, which were then incubated in contact with cells for 48 h. Culture medium and 0.78% NAg solution were used as negative and positive controls, respectively. Cell viability was determined by MTT and Trypan Blue assays. ANOVA and the Tukey test (α=0.05) were used for statistical analyses. Results: Both tests revealed a significant decrease in cell viability in all groups of resin modified cements ( p ˂0.001). There were no statistically significant differences between groups with and without NAg ( p ˃0.05). The differences in cell viability between any group of conventional GIC and the negativ e control were not statistically significant ( p >0.05). Conclusions: NAg did not affect the cytotoxicity of the GIC under evaluatio
