Comparative immunoexpression of ICAM-1, TGF-?1 and ki-67 in periapical and residual cysts

This study compared the immunohistochemical expression of ki-67, transforming growth factor beta 1 (TGF-?1) and intercellular adhesion molecule-1 (ICAM-1) in inflammatory periapical cysts and residual cysts. The study sample was composed by 25 periapical cysts and 25 residual cysts and immunohistochemical reactions were carried out using antibodies directed against ICAM-1, TGF-?1 and ki-67. Clinical, radiological, gross, histological and immunohistochemical data were tabulated for descriptive and comparative analysis using the SPSS software and differences were considered statistically significant when p<0.05%. There were no differences between the expression of ICAM-1 (p=0.239) and TGF-?1 (p=0.258) when comparing both groups. Ki-67 labeling index was higher in residual cysts compared to periapical cysts (p=0.017). Results from the present study suggest that some specific inflammatory stimuli on residual cysts would modulate their mechanisms of etiopathogenesis, growing and repair

Uso variável de nós e a gente em jornais publicados na Cidade de Goiás

The sociolinguistic studies (LOPES, 1998, 2003a, 2003b, 2004, 2007 among others) have shown that the pronominal form a gente is implemented in Brazilian Portuguese (henceforth PB), appearing as an alternative to the pronoun nós. In dealing with this subject, the present article presents part of a broader research on the variation of the subject pronouns a gente and nós in a written corpus of the City of Goiás-GO. For this research, it was considered pertinent to investigate when the innovative pronominal form began to be used by the vilaboenses (gentilic adjective to the natives of the city). For doing so, it was decided to search for old texts in the city, published in newspapers and periodicals, from its foundation until meantime of the capital transference to Goiânia. In this way, observing the periods, it is still desired to verify in which textual genres the form was more used and if the variant nós was more recurrent. The research focuses on the studies of Labovian-based Variation Theory (LABOV, 2008; WEINREICH; LABOV; HERZOG, 2006) and the classical grammaticalization theories in order to investigate first-person plural pronominal variation in Brazilian Portuguese (CASTILHO, 1997, 2016; LOPES, 1998, 2003a, 2003b, 2004; VIANNA; LOPES, 2015, among others). The analysis of the data points out to occurrences of a gente (appearing as a substitute of the subject nós) in the 1800’s, in the vilaboense community, in less formal contexts, while the form nós prevaisl in more formal contexts.As pesquisas sociolinguísticas (LOPES, 1998, 2003a, 2003b, 2004, 2007 e outras) têm demonstrado que a forma pronominal a gente está implementada no Português Brasileiro (doravante PB), figurando como alternativa ao pronome nós. Ao tratar dessa temática, o presente artigo apresenta parte de uma pesquisa mais ampla acerca da variação dos pronomes-sujeito nós e a gente em um corpus escrito da Cidade de Goiás-GO. Para esta pesquisa, julgou-se pertinente investigar quando a forma pronominal inovadora começou a ser utilizada pelos vilaboenses (gentílico aos nativos da cidade). Para tanto, optou-se por realizar busca de textos antigos na cidade, publicados em jornais e periódicos, desde a sua fundação, até meados da transferência da capital para Goiânia. Dessa maneira, observados os períodos, almeja-se ainda verificar em quais gêneros textuais a forma esteve mais presente e se a variante nós era mais recorrente. A pesquisa está calcada nos estudos da Teoria Variacionista de base laboviana (LABOV, 1978, 2008; WEINER; LABOV, 1983; WEINREICH; LABOV; HERZOG, 2006) e nas  pesquisas sobre gramaticalização clássica, a fim de investigar a variação pronominal de primeira pessoa do plural no Português Brasileiro (CASTILHO, 1997, 2016; LOPES, 1998, 2003a, 2003b, 2004; VIANNA; LOPES, 2015, dentre outros), A análise dos dados aponta para ocorrências da forma a gente (figurando como pronome-sujeito substituto de nós) nos anos 1800, na comunidade vilaboense, em contextos menos formais. Por outro lado, a forma nós prevalece nos contextos mais formais

Germinación de semillas después del fuego: un estudio con una planta que habita áreas no propensas al fuego

After a fire event, germination of seeds with hard coats can be enhanced. In the present study, we investigated whether germination of Mimosa bimucronata (DC.) Kuntze (Fabaceae) seeds, which present hard coats, is increased after fire, even though these trees usually occur in damp areas, where fire is a transient event. Fire events were manipulated in trays filled with soil covered with different amounts of dry grasses, characterizing three treatments: a) 0g (control group); b) 300g, and c) 450g of dry grass. Burning treatments were applied to seeds positioned either on the soil surface or buried in the soil. Germination experiments were carried out at 0-h and 24-h after fire to obtain the germination percentage and the Germination Speed Index (GSI). For buried seeds, the control and the 300g treatments presented significantly higher germination percentages than the 450g treatment. On the other hand, the GSI was significantly higher in the 300g treatment. Significant differences were not found between 0-h and 24-h. Seeds on the soil surface did not survive after burning. Our study showed that temperatures around 100 degrees C significantly decrease the germinability of M. bimucronata seeds. However, when seeds were buried, the germination percentage did not differ between the control group and the 300g treatment. Results also suggest that temperatures around 60 degrees C may enhance the velocity of germination of M. bimucronata seeds.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Sao Paulo State Univ Uncsp, Dept Bot, IB, BR-18618000 Botucatu, SP, BrazilFed Univ Sao Paulo Unifesp, Dept Biol Sci, BR-09941510 Diadema, SP, BrazilFed Univ Sao Paulo Unifesp, Dept Biol Sci, BR-09941510 Diadema, SP, BrazilFAPESP: 05/57999-3FAPESP: 04/06737-6Web of Scienc

Estratégias de comunicação mercadológica em rótulos de alimentos consumidos por crianças

OBJECTIVE: Analyze marketing communication strategies (MCS) of labels of food products consumed by children under 5 years of age from the Brazilian National Health System (SUS) in the city of Rio de Janeiro. METHODS: In total, 390 labels of ultra-processed foods and industrialized baby foods were analyzed. The products were organized by similarity into 24 groups. Photographs of labels from each group were analyzed to identify the MCS, which were categorized into “presence of characters and/or celebrities,” “emotional appeal,” “freebies offering,” “health appeal,” “sensory stimulation,” “brand or slogan use,” “promotional price,” “advertisement under advertisement,” and “sustainability appeal.” The percentage frequency of labels according to the number of MCS per label; the total and average frequency of MCS according to the food group; the frequency of MCS type according to the food group; and communication resources by type of MCS were computed. RESULTS: 1 to 19 strategies were found per label and an average of 7.2 MCS per label, totaling 2,792 occurrences. The MCS “sensory stimulation,” “health appeal,” “brand or slogan use,” and “advertisement under advertising” were observed in all food groups. “Freebies offering” and “promotional price” were observed in eight and six food groups, respectively. In food groups of bread; dairy products; and sweets, candies, and goodies, all nine types of MCS included in the study were identified. The groups that presented fewer types of MCS (n=5) were: peanuts, instant noodles, and margarines. Of the total MCS identified on the labels, the most frequent were “sensory stimulation” (29.4%) and “health appeal” (18.2%); and the least frequent were “freebies offering” (0.8%) and “promotional price” (0.4%). The “emotional appeal” strategy presented the highest diversity of communication resources. CONCLUSION: Rigorous regulatory measures are required to protect consumers from massive exposure to MCS on food labels.OBJETIVO: Analisar estratégias de comunicação mercadológica (ECM) presentes em rótulos de produtos efetivamente consumidos por crianças menores de 5 anos usuárias do Sistema Único de Saúde na cidade do Rio de Janeiro. MÉTODOS: Foram analisados 390 rótulos de alimentos ultraprocessados e papas infantis industrializadas. Os produtos foram organizados por similaridade em 24 grupos. Realizou-se a análise das fotografias dos rótulos de cada grupo para a identificação das ECM, que foram categorizadas em: “presença de personagens e/ou celebridades”, “apelo emocional”, “oferta de brindes”, “apelo à saúde”, “estímulos aos sentidos”, “uso da marca ou slogan”, “preço promocional”, “propaganda sob propaganda” e “apelo à sustentabilidade”. Foram computadas: frequência percentual de rótulos segundo número de ECM por rótulo; frequência total e média de ECM segundo grupo de alimentos; frequência do tipo de ECM segundo grupo de alimentos; e recursos comunicacionais por tipo de ECM. RESULTADOS: Constataram-se de uma a 19 estratégias por rótulo e média de 7,2 ECM por rótulo, totalizando 2.792 ocorrências. As ECM “estímulo aos sentidos”, “apelo à saúde”, “uso da marca ou slogan” e “propaganda sob propaganda” foram observadas em todos os grupos de alimentos. Já “oferta de brindes” e “preço promocional” apareceram em oito e seis grupos de alimentos, respectivamente. Nos grupos pães, lácteos e doces, balas e guloseimas, foram identificados os nove tipos de ECM incluídos no estudo. Os grupos que apresentaram menos tipos de ECM (n = 5) foram: amendoins, macarrões instantâneos e margarinas. Do total de ECM identificadas nos rótulos, as mais recorrentes foram “estímulo aos sentidos” (29,4%) e “apelo à saúde” (18,2%); e as menos frequentes foram “oferta de brindes” (0,8%) e “preço promocional” (0,4%). A ECM “apelo emocional” apresentou a maior diversidade de recursos comunicacionais. CONCLUSÃO: São necessárias medidas regulatórias rigorosas que protejam o consumidor da massiva exposição às ECM em rótulos de alimentos

Clinical and radiological analysis of a series of periapical cysts and periapical granulomas diagnosed in a Brazilian population

Periapical cysts (PC) and periapical granulomas (PG) are the two most common chronic inflammatory periapical diseases, but their clinicoradiological characteristics can vary depending on the methods employed in each study. The aim of the present work was to analyze the clinical and radiological profile of a series of PC and PG diagnosed in a Brazilian population. The files of two Oral Pathology laboratories were reviewed and all cases diagnosed as PG and PC were selected for the study. Clinical and radiological information were retrieved and data were tabulated and descriptively and comparatively analyzed. Final sample was composed by 647 inflammatory periapical lesions, including 244 PG (38%) and 403 PC (62%). The number of women affected by PG was significantly higher than the number of women affected by PC (p=0.037). Anterior region of the maxilla was the most common affected area for both entities (39% of the cases), but the most common anatomical location of PG (anterior maxilla and posterior maxilla) was different from PC (anterior maxilla and posterior mandible) (p<0.0001). Upper lateral incisor was the most affected tooth. The mean radiological size of the PC was larger than the mean radiological size of the PG (p<0.0001) and PC showed well-defined radiological images more frequently than PG (p<0.0001). PC were more common than PG, both showed predilection for adult females, most lesions affected predominantly the anterior maxilla and PC presented larger mean radiological diameter and well-defined images when compared with PG

Verbal recognition of infants with cleft lip and palate with and without history of risk indicators for hearing loss

Os primeiros dois anos de vida são críticos para a aquisição e desenvolvimento de habilidades auditivas e linguagem. OBJETIVO: Verificar o desempenho de lactentes com fissura labiopalatina (FLP) com e sem indicadores de risco à audição (IRA) no teste de reconhecimento verbal (TRV). Estudo prospectivo. MATERIAL E MÉTODOS: Pais de 100 lactentes (9 a 18 meses) com FLP foram entrevistados para verificar a presença de IRA e à constituição dos grupos em estudo. Todos os lactentes foram submetidos ao TRV. Resultados: Doenças otológicas, não-amamentação natural, tabagismo dos pais, insuficiência das vias aéreas superiores, permanência na incubadora e antecedentes com surdez foram os IRA mais freqüentes. 85 lactentes apresentaram IRA e 40% deles TRV alterado. 15 não apresentaram IRA e 73% apresentaram desempenho no TRV esperado para a sua idade. Não foi encontrada significância (p=0,326) entre os grupos. 54 lactentes apresentaram história de otite média (OM) e 31% deles tiveram alteração no TRV. 46 não apresentaram OM e apresentaram desempenho no TRV esperado para a sua idade. Encontrada diferença significativa (p=0,000). CONCLUSÃO: Identificou-se a presença de outros IRA além FLP. O desempenho dos lactentes com e sem histórico de IRA não diferiu no TRV. A presença de doenças otológicas interferiu significativamente no TRV.The first two years of life are critical for the acquisition and development of hearing and speaking skills. AIM: This prospective study aims to verify the performance of infants with cleft lip and palate (CLP) with and without risk factors for hearing (RFH) in the verbal recognition test (VRT). MATERIAL AND METHOD: The parents of 100 infants (9 to 18 months of age) with CLP were interviewed to investigate the presence of RFH and to sort out the characteristics of the study groups. All infants underwent VRT. RESULTS: Otologic diseases, lack of breastfeeding, parental smoking, upper airway insufficiency, stay in an incubator, and family history of hearing impairment were the most frequent RFH. Eighty-five infants had RFH, among which 40% had altered VRT results; fifteen did not have any RFH and 73% performed as expected for their age range in the VRT. There was no significant difference (p=0.326) between groups. Fifty-four infants had history of otitis media (OM), among which 31% had altered VRT results; forty-six had no history of OM and performed as expected for their age range in the VRT; Statistically significant difference (p=0.000) was found. CONCLUSION: Other risk factors for hearing aside CLP were found. Infants with and without history of RFH performed similarly in the VRT. The presence of otologic diseases significantly interfered with the VRT
