RESUMO:O estudo foi realizado no período de fevereiro de 2007 a maio de 2008, em vinte e uma comunidades rurais do município de Oeiras (07º00'54''S e 42º08'06''W), localizadas em área de transição vegetacional Caatinga/Cerrado, onde predomina a Caatinga. Objetivou-se conhecer as plantas tradicionalmente utilizadas pela população com fins terapêuticos. As coletas botânicas seguiram metodologia usual e os exemplares identificados foram incorporados ao acervo do Herbário Graziela Barroso (TEPB). Como procedimento metodológico realizou-se entrevistas semi-estruturadas com formulários padronizados a 20 moradores indicados por líderes comunitários locais como pessoas de reconhecido saber, que acompanharam as coletas. As espécies citadas foram agrupadas em de17 categorias de acordo com a Organização Mundial de Saúde (OMS). Os dados quantitativos foram obtidos através do cálculo da Importância Relativa (IR) para cada espécie e do Fator de Consenso dos Informantes (FCI). Assim, identificou-se 167 etnoespécies, distribuídas em 59 famílias botânicas e 143 gêneros, sendo 65,86% nativas. As famílias com maior representatividade em número de espécies foram a Leguminosae (28) e a Euphorbiaceae (18). Os gêneros mais representativos foram Croton L. (9)Allem. e Lippia alba L., obtiveram os maiores valores de IR de 1,79; 1,86; 1,21; 1,14; respectivamente. Salienta-se a elevada frequência de usos terapêuticos destas espécies, concentradas no tratamento dos transtornos do sistema respiratório (56 espécies) e das doenças infecciosas intestinais, hepáticas e helmintíases (65), sendo gripe e diarréia as doenças mais citadas. A folha é a parte do vegetal mais utilizada na medicina caseira local (31,5% dos casos) e as formas de preparo mais utilizadas são a decocção (32,2% dos casos) seguida por infusão (23,8%). Estes dados possibilitam inferir que os moradores das comunidades rurais possuem conhecimento acerca das plantas utilizadas como medicinais, especialmente as nativas. The aim was to know the plants traditionally used for therapeutic purposes by the population. The botanical harvests followed the usual methodology and the identified specimens were incorporated into the collection from the Herbarium Graziela Barroso (TEPB). As methodological procedure, semi-structured interviews by using standardized forms were done with 20 dwellers indicated by local community leaders as people presenting notorious knowledge and who accompanied the harvests. The cited species were grouped into 17 categories, according to the World Health Organization (WHO). Quantitative data were obtained by calculating the relative importance (RI) for each species and the informant consensus factor (ICF). We identified 167 ethnospecies, distributed into 59 botanical families and 143 genera, from which 65.86% were native. The most representative families in number of species were Leguminosae (28) and Euphorbiaceae (18). The most representative genera were Palavras
The objective of this study was to evaluate the influence of the type of cerebral palsy (CP) and oral motor function (OMF) on the oral health status of children and adolescents with CP in Teresina, Piauí, Brazil. The sample consisted of 52 children with CP, aged 7 to 18 years. The data were statistically analyzed using chi-square tests. In 73.1% of the sample, the subjects’ caregivers carried out the daily oral care. There was a significant association between the frequency of daily care and the subject's level of oral hygiene (p = .037). A diagnosis of Class II malocclusion was made for 55.8% of the sample, and defects of enamel formation were found in 38.5% of the subjects. There was no significant correlation between DMFT (decayed, missing, filled teeth) (mean = 1.09 ± 1.64) and socioeconomic status of the subjects (r = .254, p = .069). A significant association was found between quadriplegia and OMF (χ2 = 7.88, p = .019). The type of CP and OMF did not influence the levels of plaque and caries indices in the children with CP, but increased frequency of toothbrushing did result in an improved oral hygiene index.
The objective was to assess the oral health status, the treatment needed, and the type of dental health services access of intellectually disabled (ID) subjects in Teresina, Brazil. The sample consisted of 103 ID subjects matriculated in centers for special needs people and 103 siblings. Results were analyzed using paired t-test, chi-square test, and odds ratio. ID subjects had fair (63.1%; p < .001) and their siblings had a good oral hygiene (n = 103 [55.3%]; p < .005). ID had more decayed (3.52; p < .005), and missing teeth (1.17; p = .001), fewer dental restorations (1.67; p = .012) and had a greater need for tooth extraction (21.4%; p = .002) than their siblings. Thirty percent of ID subjects had never received dental treatment and had difficulty accessing public health services. Their treatment needs were, therefore, higher than non-ID subjects. The access to oral health services was unsatisfactory, thus it is important to implement educational and health promotion inclusion policies for people with ID.
Oral health, assessed through PI and GI, deteriorates after a short period of hospitalization.
The objective was to evaluate the history of traumatic dental injury (TDI) among children with and without autism spectrum disorders (ASD) at the Centro Integrado de Educação Especial (CIES), in Teresina, Brazil. The dental records of 228 children, 114 with ASD (SG = study group) and 114 without ASD (CG = control group), paired by age, gender and socioeconomic characteristics between January 2007 and September 2014 were reviewed. Data were analyzed using chi-square test and multivariate logistic regression (alpha = 5.0%). Dental trauma in SG was lower than in the CG (24.6% and 41.2%, respectively, p = 0.007). The risk of trauma was lower among males in SG (OR: 0.35; 95%CI: 0.18 to 0.67). The likelihood of TDI in SG was 3.17 higher in females than that of males (p = 0.040). The prevalence of TDI was lower in ASD individuals compared to controls. Dental trauma was higher among ASD girls than ASD boys.
(25.43 and 14.28%, respectively) than the conventional tomatoes (19.52 and 11.33%, respectively). Organic tomatoes had higher antioxidant potential probably due to its higher ascorbic acid and total phenolic values.
Supramolecular self-assembly has been demonstrated to be a useful approach to developing new functional nanomaterials. In this work, we used a cobalt Prussian blue analogue (PBA, Co3[Co(CN)6]2) compound and a β-cyclodextrin (CD) macrocycle to develop a novel host-guest PBA-CD nanomaterial. The preparation of the functional magnetic material involved the self-assembly of CD molecules onto a PBA surface by a co-precipitation method. According to transmission electronic microscopy results, PBA-CD exhibited a polydisperse structure composed of 3D nanocubes with a mean edge length of 85 nm, which became shorter after CD incorporation. The supramolecular arrangement and structural, crystalline and thermal properties of the hybrid material were studied in detail by vibrational and electronic spectroscopies and X-ray diffraction. The cyclic voltammogram of the hybrid material in a 0.1 mol·L−1 NaCl supporting electrolyte exhibited a quasi-reversible redox process, attributed to Co2+/Co3+ conversion, with an E1/2 value of 0.46 V (vs. SCE), with higher reversibility observed for the system in the presence of CD. The standard rate constants for PBA and PBA-CD were determined to be 0.07 and 0.13 s−1, respectively, which suggests that the interaction between the nanocubes and CD at the supramolecular level improves electron transfer. We expect that the properties observed for the hybrid material make it a potential candidate for (bio)sensing designs with a desirable capability for drug delivery.
