title: Assessment of Rainfall Estimates from the TRMM-3B43 Product in the State of Amazonas

description: ABSTRACTThe aim of this study was to evaluate the rainfall data via satellites in Amazonas state, Brazil. To this end, the estimates from the TRMM-3B43 product (2004-2008) were compared with data from seven Conventional Weather Stations (CWS). The comparison was based on the following statistical parameters: Average Error (AE), Root Mean Square Error (RMSE), linear correlation coefficient (r), and Wilmott’s index of agreement (d). The TRMM-3B43 estimates were similar to the surface data and represent well the seasonal variability of rainfall. The data showed high linear correlation (r = 0.83), high index of agreement (d = 0.85), and satisfactory RMSE (66.6 mm/month). Therefore, rainfall estimates from the TRMM-3B43 product can be used as an alternative source of quality data.

title: Treating sunflower seeds subjected to ozonization

description: Abstract:Sunflower crops (Helianthus annuus L.) are a source of pathogens that can be transmitted by means of the seeds. An alternative for the treatment of seeds can be the application of an ozone compound, which has been used in various segments to eliminate microorganisms. Three lots of the Embrapa 122 variety have been used to assess the efficacy of ozone to control pathogens in sunflowers seeds. To typify the profile of the lots we have determined the moisture content, the first germination counting, the germination, the germination speed index, emergence, initial stand, emergence speed index and health. The lots have been stored in an ozone-rich environment for periods of 20, 60 and 120 minutes and without ozone (control). After the treatments, the seeds were tested to assess their health and physiological quality through the said tests as well as a test for accelerating aging, tetrazolium and incidence and severity of fungi. It has been concluded that the treatment for H. annuus seeds, Embrapa 122 variety, with ozone concentration of 1741 ppmv (0.24 g/h), for 60 minutes, reduces the fungal presence of Alternaria sp., Fusarium sp., Aspergillus sp. and Penicillium sp. without affecting their physiological potential.

title: Agreement between clinical and histopathological diagnoses of oral lesions diagnosed in clinic university

description: BACKGROUND: The diagnosis of wide variety of lesions occurring in the oral cavity is critical to the practice of dentistry. It is common for dentists to find oral lesions of doubtful diagnosis. In these situations, the dentist should consider the indication of biopsy as a complement or even conclusive final diagnosis of these oral lesions. The evaluation of the agreement between the clinical and histopathological diagnosis of oral lesions allows the accuracy and ability analysis of the professional or his/her dentistry academic level to perform clinical diagnosis correctly OBJECTIVE: This study aimed to evaluate the correlation between clinical and histopathological diagnosis of oral lesions diagnosed in a university dental clinic. METHOD: This is an analytical, retrospective study conducted with patients biopsied and who had pathologic reports issued between February 2010 and July 2012. The SPSS 17.0 for Windows was used for data analysis. We conducted descriptive analyzes of the data. The concordance between the diagnoses was also measured using kappa statistics. RESULT: It was obtained through a sample of 125 patients. The average age was 48.64 years, with a majority of women (58.4%). The histopathological diagnoses were the most prevalent non-neoplastic proliferative processes (36.6%). The concordance between the clinical and histopathological diagnosis occurred in most patients (87.8 %). The kappa value for the agreement between diagnoses was 0.75 CONCLUSION: The concordance between the diagnoses occurred in most patients investigated presented corresponding to substantial agreement.

title: Effect of different solutions used as final irrigant on dentin surface: roughness analysis

description: INTRODUCTION : The use of irrigators can create microstructural changes in the dentin surface, including changes in roughness. These changes may influence the bonding process of filling materials to dentin. OBJECTIVE: The aim of this study was to evaluate the effect of EDTA, sodium hypochlorite or chlorhexidine, as final irrigant, in the roughness of the dentin surface. MATERIAL AND METHOD: Distal root of 6 mandibular molars were used. The roots were flatted with the aid of sandpaper and segmented, totaling 18 samples. The initial analysis was performed by using Dektak profilometer. Five areas were scanned per sample. Then, the samples were irrigated with NaOCl to simulate the chemomechanical preparation and washed with distilled water. The segments were divided into six groups according to the final flush protocol: Distilled water, 5.25% NaOCl, 2% chlorhexidine, 17% EDTA, 17% EDTA+ 5.25% NaOCl, 17% EDTA+ 2% chlorhexidine. Once again, in each sample, five areas were scanned, totaling 15 scans per group. Data were statistically analyzed using Kruskal - Wallis and Mann -Whitney tests (p&lt;0.05). RESULT: Significant changes in roughness were found only in the association of the chelating agent with NaOCl. CONCLUSION: The final irrigation protocols have different effects on surface roughness of dentin.

title: Glycemic control and the production of cytokines in diabetic patients with chronic periodontal disease

description: ABSTRACT Objective: To evaluate the association of glycemic control and cytokine production in type 2 diabetic subjects with chronic periodontitis Methods: Gingival biopsies were performed in 40 patients, divided into four groups: systemically healthy subjects without periodontal disease (S); systemically healthy patients with chronic periodontitis (P); patients with well-controlled type 2 diabetes mellitus (DM) with chronic periodontitis (C); poorly controlled type 2 diabetes mellitus with chronic periodontitis (D). The production of interleukin (IL) -4, -6, -10, -17 and interferon (IFN) -γ was quantified by ELISA. Results: The production of IL-4, IL-10, IL-17 and INF-γ was higher on group D when compared to other groups (p &lt;0.05), which in turn were similar (p ≥0.05). In addition, there was no difference in the production of IL-6 in any of the evaluated groups (p≥0.05). Conclusion: Were observed significantly elevated levels of pro-inflammatory and anti-inflammatory cytokines in patients with poorly controlled type 2 diabetes and chronic periodontitis, demonstrating that glycemic control may be associated to the immune inflammatory response of sites with chronic periodontitis.

title: Sanitary quality of the rivers in the Communities of Manguinhos´ Territory, Rio de Janeiro, RJ

description: Abstract Sanitation actions are rare in the communities of Manguinhos, so evaluation of the sanitary conditions of the river waters and the peridomestic soils of the communities allows the diagnosis of the risk of contamination. This study evaluated coliform levels (total coliforms and Escherichia coli) by the filter membrane method, and parasitological (by adapted Lutz and Baermann-Moraes methods) in the waters and soils of the Faria-Timbó, Jacaré and Canal do Cunha Rivers that pass through the communities of the Territory of Manguinhos, RJ, according to the standards established in Brazilian legislation. In all points of the rivers, the water was unfit, with an average level of Escherichia coli 3,800 times higher than that standardized in CONAMA Resolution No. 274/2000. Larvae, helminths eggs and protozoan oocysts were observed. Soil samples were also unfit, with mean total coliform level 77,000 times higher than that considered acceptable by SMAC Resolution 468/2010. The Escherichia coli average level was 53,000 times higher than that permitted by the legislation. However, helminths eggs were found in only one soil sample. It was concluded that the lack of sanitation in this locality results in the high coliform and parasitological levels of the river waters and in the peridomestic soils, and that immediate modifications are needed to the Brazilian environmental paradigm, which uses its water bodies as sewage disposal ditches.

title: Challenges for dignified care in homes for the aged

description: Abstract This article aims to present a descriptive and qualitative study to understand how care is implemented at the end of life in homes for the aged in the metropolitan region of Porto Alegre, Brazil. We interviewed 19 members from the technical team and 13 staff responsible for taking care of the institutionalized elderly. In this sense, we sought to investigate whether institutions are structured to recognize the need for care to ensure comfort and dignity in the dying process of their patients. From the analysis of the content from interviews and observations, it can be said that some of these structures are precarious. A relationship between care quality and availability of financial resources was also identified, demonstrating reification of care, that is, care is regarded as a commodity. In this way, bioethics of protection would be a tool to overcome the challenge for dignified care.

title: Association Between Chocolate Consumption and Severity of First Infarction

description: Abstract Background: Cardiovascular diseases, such as acute myocardial infarction, are the main causes of death in the world. The flavonoids present in chocolate can have benefits for people who have risk factors to the development of cardiovascular diseases and have a coadjuvant effect on known therapies. Objective: To analyze the association between chocolate consumption, severity of coronary lesions, risk factors and severity of the first infarction in patients attended at the Cardiology Institute of Santa Catarina and other hospitals in the State of Santa Catarina. Methods: Subanalysis of the Catarina Heart Study cohort, evaluated 350 patients with first myocardial infarction. We evaluated clinical, echocardiographic, hemodynamic laboratorial variables. We used chi square test to evaluate qualitative variables, t student test in the case of parametric variables and U Mann Whitney test in non-parametric variables. We considered significant p &lt; 0,05. Results: Lower prevalence of hypertension (43.2% % vs. 62.3% p = 0.003), diabetes mellitus (13.5% vs. 25.7%, p = 0.027) and smoking (24.3% vs. 37.7%, p = 0.032) among those who consume chocolate. Higher use of alcohol (40.5% vs. 26.4%, p = 0.018) and drugs (9.5% vs. 3.3%, p = 0.023) among those who consumed chocolate. Among the patients who consumed chocolate, there was a negative correlation between amount consumed and Syntax (r = -0.296, p = 0.019). Conclusion: There was association between chocolate consumption and lower prevalence of hypertension, diabetes and smoking. There was no association between amount of chocolate consumed and post-infarction ventricular function and TIMI frame count. Higher prevalence of alcohol and drug use among those who consume chocolate. Negative correlation between Syntax and the amount of chocolate consumed.

title: ON A FIREWOOD, I AM BLAZE: POETICS OF MEMORY IN A KRAHÔ RITUAL CHANT

description: Abstract This paper presents the transcription and translation of the lyrics of a Krahô ritual chant, Amerindian people who live in the north of the ê language. This chant is an exemplary piece of one of the several genres of verbal arts found among the Krahô, which constitute central expressives forms in their vast and complex ritual system. I propose here a cross-exercise in which the ethnographic commentary enriches the translation, and the commentary on translation enriches the ethnography, both movements contributing to a more detailed understanding of the text and its context. On that basis, I interpret this chant as a reflection on its own process of transmission and as a place of elaboration of a poetics of memory

title: Morphoanatomy of fruit, seed and seedling of Ormosia paraensis Ducke

description: Ormosia paraensis Ducke, known as "tento", has seeds that are used to make handcrafts and wood that is worked on by furniture makers. For forest identification and seeds technology, the information about the morphoanatomy of their fruits, seeds and seedlings is scarce. Therefore, the purpose of this study was to morphoanatomically describe the fruit, seeds and the post-seminal development of "tento". For the morphoanatomical description, the evaluations were examined by optical and electron microscopy scanning. The fruit is a nutant legume, brown to black, dehiscent and with one or two seeds of lateral placentation, being the epicarp slim, the mesocarp woody and the endocarp spongy, measuring about 4.4 cm, 3.9 cm and 2.0 cm in length, width and thickness, respectively. The seeds are bitegmic, exalbuminous and rounded with average dimensions: length of 12.36 mm, width of 9.68 mm and thickness of 8.03 mm. The "tento" seedlings have simple and alternate leaves, with tap roots and cylindrical stem, being its germination hypogeal cryptocotyledonary.
