title: Dynamics of the Brazilian Exports of Natural Honey Between 2000 and 2011

description: This study aimed to describe the dynamics of the Brazilian exports of natural honey in the 2000-2011 period. To this end, a literature survey on exports of natural honey was carried out at the following reference data sources: SEBRAE, IBGE, Aliceweb, and UNcomtrade. The concentration ratio (CR) methodology was also applied to define the degree of concentration; this calculation was based on the participation of the four and the eight largest Brazilian export markets. The results showed that Brazil evolved from a low volume of exports in 2000 to the 5th place in world exports in 2011, exporting mainly to the United States, Germany, United Kingdom, Canada, Spain and Belgium. The United States and Germany participated with more than 80% of the total Brazilian exports of natural in the period studied, indicating a high market concentration proven by the methodology applied.

title: Edaphic Beetle Fauna in Eucalyptus Under Different Systems of Chemical Control of Weed Competition

description: Eucalyptus grandis stands out as one of the most cultivated species in Brazil because of its productivity and wood quality. The objective of this study was to assess the edaphic coleopteran fauna in an initial planting of E. grandis under different systems of weed control in Santa Maria, Rio Grande do Sul state, using pitfall traps. The treatments were based on the chemical control of weeds: total, in and between planting rows (CT); total, in the planting row (CL); monocotyledons, in and inter-rows (CM); dicotyledons, in and inter-rows (CD); control of one meter next to the planting row, leaving one meter between rows without control (CF); and without control (SC) . From March 2011 to August 2012, 1190 beetles of seven families were collected. There were differences between the edaphic coleopteran fauna captured in the evaluated treatments. The application of a smaller amount of herbicide maintains plant diversity, allowing greater diversity of beetle fauna in the area.

title: HISTOLOGICAL ANALYSIS OF THE INTESTINAL TRACT OF Caracara plancus (Miller, 1777)

description: Abstract The Southern Crested Carcara is a bird with a recognized ecological role in the population control of small birds and mammals, feeding on live prey as much as on decaying animals. The objective of this study was to analyze the histology of Carcara`s intestinal tract of five Carcaras from the Wild Animal Screening Center of Pernambuco were euthanized to remove their intestines and cloacae. The tissues were stained with Hematoxylin/Eosin, Alcian Blue pH 1.0, and Periodic Acid Schiff. The villi of the small and large intestines are lined with a simple columnar epithelium with microvilli membranes and goblet cells. The lamina contains lymphocytes and form lymphatic follicles within some of the villi. The mucosal muscle is arranged in a longitudinal direction. The submucosal layer was only observed in the cloaca and the muscle layer has transverse and longitudinal fibers. The serous membrane lines the whole intestinal tract and is composed of mesothelium and submesothelial connective tissue. Longitudinal folds were found in the large intestine. The conclusion is that the Carcara`s intestine exhibits an overall structure compatible with the histological pattern observed in other species of birds; however, Paneth cells and the submucosal layer were not observed. Lymph follicles were found inside the villi and a high number of goblet cells at the end of the ileum and large intestine.

title: Social network analysis as a strategy for monitoring the dissemination of information between hospitals

description: Abstract This article explores the structure of connections between the hospitals that are members of a hospital management innovation and learning network. This study was based on the assumption that there are limitations to encourage the communication and diffusion of knowledge between health service organizations if they are not effectively connected through social networks. Social Network Analysis was used as a strategy for monitoring the dissemination of information between hospitals. Theoretical concepts of diffusion of knowledge allowed emphasizing the role of the phenomena and communication and learning processes as the driving forces for health service innovation. The results showed weak interactions between hospitals and a lack of cohesion within the network. Therefore, there is a need for policies to promote the flow of data and information, which requires network openness to foster the exchange of innovative processes. Interactions between these hospitals in horizontal and disseminated structures have yet to be stimulated, established, incorporated, and developed by individuals, institutions and health service organizations.

title: Interplay of TGFβ signaling and microRNA in thyroid cell loss of differentiation and cancer progression

description: ABSTRACT Thyroid cancer has been rapidly increasing in prevalence among humans in last 2 decades and is the most prevalent endocrine malignancy. Overall, thyroid-cancer patients have good rates of long-term survival, but a small percentage present poor outcome. Thyroid cancer aggressiveness is essentially related with thyroid follicular cell loss of differentiation and metastasis. The discovery of oncogenes that drive thyroid cancer (such as RET, RAS, and BRAF), and are aligned in the MAPK/ERK pathway has led to a new perspective of thyroid oncogenesis. The uncovering of additional oncogene-modulated signaling pathways revealed an intricate and active signaling cross-talk. Among these, microRNAs, which are a class of small, noncoding RNAs, expanded this cross-talk by modulating several components of the oncogenic network – thus establishing a new layer of regulation. In this context, TGFβ signaling plays an important role in cancer as a dual factor: it can exert an antimitogenic effect in normal thyroid follicular cells, and promote epithelial-to-mesenchymal transition, cell migration, and invasion in cancer cells. In this review, we explore how microRNAs influence the loss of thyroid differentiation and the increase in aggressiveness of thyroid cancers by regulating the dual function of TGFβ. This review provides directions for future research to encourage the development of new strategies and molecular approaches that can improve the treatment of aggressive thyroid cancer.

title: The relationship of flavonoid intake during pregnancy with excess body weight and gestational diabetes mellitus

description: ABSTRACT Objective: To investigate the relationship of flavonoid intake during pregnancy with maternal excessive body weight and gestational diabetes mellitus (GDM). Subjects and methods: A cross-sectional study was conducted among 785 adult women in singleton pregnancies, and data were collected at the time of the oral glucose tolerance test. For the body mass index (BMI) classification according to the gestational age, the criteria of Atalah was used, and the diagnosis of GDM was based on the World Health Organization of 2014. Two 24-hour dietary recalls were obtained, and the usual intake was determined by the Multiple Source Method. Adjusted multinomial logistic regression was used to investigate the relationship of the flavonoids with overweight and obesity, and adjusted non-conditional logistic regression for the relationship of the flavonoids with GDM. Results: The mean (SD) age of the women was 28 (5) years, 32.1% were overweight, 24.6% were obese and 17.7% were diagnosed with GDM. The median (P25, P75) of total flavonoid intake was 50 (31,75) mg/day. Considering the eutrophic women as the reference, the pregnant women with a higher total flavonoid intake [OR 0.62 (95% CI 0.38; 0.96)] and anthocyanidin intake [OR 0.62 (95% CI 0.40; 0.99)] were less likely to be obese when compared to the women with lower intakes. No association of the flavonoids intake with overweight or GDM was found. Conclusion: A very low intake of flavonoids was observed. The data suggest that the intake of foods naturally rich in total flavonoids and anthocyanidin has a beneficial role regarding obesity among pregnant women.

title: Spatial and Height Distribution of Harvested Rupestrian Field Species in Preserved and Cultivated Communities

description: ABSTRACT This study aimed to compare the spatial and the height distribution of three plant species between two rupestrian field communities, one preserved (A) and the other cultivated (B). One 50 × 100 m plot was delimited in each community and the populations of Eremanthus incanus, Lychnophora pinaster and Vellozia caruncularis were assessed for height and spatial distribution (using the Ripleys’s L-function). In community A, 4,098 individuals were counted, mostly L. pinaster, against 220 individuals in community B, prevailing E. incanus. An inverted-J pattern was observed for height distribution in both communities, however, with lower frequencies in B. Regular spatial distribution was found for E. incanus and V. caruncularis in community A, whereas the pattern for L. pinaster depended on the scale of analysis. The spatial distribution of all species differed between communities. The Ecological Park Quedas do Rio Bonito contributes to the conservation of these rupestrian field species.

title: Data assimilation using the ensemble Kalman filter in a distributed hydrological model on the Tocantins River, Brasil

description: ABSTRACT In this work, the data assimilation method namely ensemble Kalman filter (EnKF) is applied to the Tocantins River basin. This method assimilates streamflow results by using a distributed hydrological model. The performance of the EnKF is also compared with an empirical assimilation method for hourly time intervals, in which two applications based on information transfer from gauged to ungauged sites and real time streamflow forecasting are assessed. In the first application, both assimilation methods are able to transfer streamflow to ungauged sites, obtaining better results when more than one station located upstream or downstream of the basin are gauged. In the second application, integration of a real time forecast model with EnKF is able to absorb errors at the beginning of the forecast. Therefore, a greater efficiency in the Nash-Sutcliffe index for the first 144 hours in advance in relation to its counterpart without assimilation is obtained. Finally, a comparison between both data assimilation methods shows a greater advantage for the EnKF in long lead times.

title: Recurrent diabetic ketoacidosis

description: ABSTRACT Objective The purpose of this study is to examine risk factors for recurrence of diabetic ketoacidosis and determine interventions to prevent future admissions. Materials and methods Review article. Results Recurrent diabetic ketoacidosis is a serious and not uncommon health problem. Diabetic ketoacidosis is associated with severe morbidity and mortality and hospital admissions due to this problem constitute a serious economic burden on the healthcare system. Younger age at diabetic ketoacidosis onset, poor baseline glycemic control and elevated HbA1C, patient comorbidities, depression, alcohol or substance abuse, particularly active cocaine use, have been associated with recurrent diabetic ketoacidosis. In addition, socioeconomic factors (such as ethnic minority status, use of public health insurance and underinsurance), psychosocial, economic, and behavioral factors (including financial constraint, stretching a limited insulin supply, and homelessness) have been all reported to be associated with readmission among diabetic ketoacidosis patients. Conclusions Identifying high-risk patients during the first diabetic ketoacidosis admission and performing relevant interventions (repeated instructions of insulin use, social help and involvement of family members in medical treatment, collaboration with the patient’s primary care physician in order to establish a close and frequent follow up program) may help prevent future admissions. Further studies need to take place to determine whether early interventions with those factors prevent future admissions.
