Symbolic effects capitalized by nurses from the National Institute of Cancer in Brazil (1980 -1990)
ABSTRACT Objective: to describe the strategies of nurses in the National Institute of Cancer to disseminate its scientifi c capital and discuss the symbolic effects capitalized in the fi eld of oncology in the 1980s. Method: historical social studies, with primary sources consisting of written documents and oral reports, and as secondary sources, articles and books on the subject, based on the French sociologist Pierre Bourdieu's concepts of scientifi c capital and habitus. Results: it revealed the effective performance of nurses in this Institute on policies of cancer prevention and control and strategies used in the teaching of oncology nursing at the undergraduate level. In conclusion, nursing stands out in this context, through the dissemination of its scientifi c knowledge, as a participant in the construction of a scientifi c fi eld of oncology nursing in Brazil, highlighting the occupation of important social areas. Key words: Nursing; History of Nursing; Oncology Nursing. RESUMO Objetivo: descrever as estratĂ©gias dos enfermeiros do Instituto Nacional de CĂąncer para divulgação do seu capital cientĂfi co e discutir os efeitos simbĂłlicos capitalizados no campo da oncologia na dĂ©cada de 1980. MĂ©todo: estudo histĂłrico-social, cujas fontes primĂĄrias constituĂram-se de documentos escritos e depoimentos orais e, as secundĂĄrias, de artigos e livros sobre o tema, fundamentado com os conceitos de capital cientĂfi co e habitus do sociĂłlogo francĂȘs Pierre Bourdieu. Resultados: evidenciou-se a efetiva atuação do enfermeiro desse Instituto nas polĂticas de prevenção e controle do cĂąncer e das estratĂ©gias utilizadas no ensino de enfermagem em oncologia no curso de graduação. Concluiu-se que a Enfermagem destacou-se, nesse contexto, atravĂ©s da difusĂŁo do seu capital cientĂfi co, como participante da construção de um campo cientĂfi co da Enfermagem oncolĂłgica no Brasil, com destaque Ă ocupação de alguns espaços sociais importantes
Areas of natural occurrence of melipona scutellaris Latreille, 1811(Hymenoptera: Apidae) in the state of Bahia, Brazil.
The bee Melipona scutellaris is considered the reared meliponine species with the largest distribution in the North and Northeast regions of Brazil, with records from the state of Rio Grande do Norte down to the state of Bahia. Considering the importance of this species in the generation of income for family agriculture and in the preservation of areas with natural vegetation, this study aimed at providing knowledge on the distribution of natural colonies of M. scutellaris in the state of Bahia. Literature information, interviews with stinglessbee beekeepers, and expeditions were conducted to confirm the natural occurrence of the species. A total of 102 municipalities showed records for M. scutellaris, whose occurrence was observed in areas ranging from sea level up to 1,200-meter height. The occurrence of this species in the state of Bahia is considered to be restricted to municipalities on the coastal area and the Chapada Diamantina with its rainforests. Geographic coordinates, elevation, climate and vegetation data were obtained, which allowed a map to be prepared for the area of occurrence in order to support conservation and management policies for the species

Insulin modulates cytokine release and selectin expression in the early phase of allergic airway inflammation in diabetic rats
<p>Abstract</p> <p>Background</p> <p>Clinical and experimental data suggest that the inflammatory response is impaired in diabetics and can be modulated by insulin. The present study was undertaken to investigate the role of insulin on the early phase of allergic airway inflammation.</p> <p>Methods</p> <p>Diabetic male Wistar rats (alloxan, 42 mg/Kg, i.v., 10 days) and controls were sensitized by s.c. injection of ovalbumin (OA) in aluminium hydroxide 14 days before OA (1 mg/0.4 mL) or saline intratracheal challenge. The following analyses were performed 6 hours thereafter: a) quantification of interleukin (IL)-1ÎČ, tumor necrosis factor (TNF)-α and cytokine-induced neutrophil chemoattractant (CINC)-1 in the bronchoalveolar lavage fluid (BALF) by Enzyme-Linked Immunosorbent Assay, b) expression of E- and P- selectins on lung vessels by immunohistochemistry, and c) inflammatory cell infiltration into the airways and lung parenchyma. NPH insulin (4 IU, s.c.) was given i.v. 2 hours before antigen challenge.</p> <p>Results</p> <p>Diabetic rats exhibited significant reduction in the BALF concentrations of IL-1ÎČ (30%) and TNF-α (45%), and in the lung expression of P-selectin (30%) compared to non-diabetic animals. This was accompanied by reduced number of neutrophils into the airways and around bronchi and blood vessels. There were no differences in the CINC-1 levels in BALF, and E-selectin expression. Treatment of diabetic rats with NPH insulin, 2 hours before antigen challenge, restored the reduced levels of IL-1ÎČ, TNF-α and P-selectin, and neutrophil migration.</p> <p>Conclusion</p> <p>Data presented suggest that insulin modulates the production/release of TNF-α and IL-1ÎČ, the expression of P- and E-selectin, and the associated neutrophil migration into the lungs during the early phase of the allergic inflammatory reaction.</p

Food insecurity, food waste, food behaviours and cooking confidence of UK citizens at the start of the COVID-19 lockdown
Purpose
The current pilot study explored food insecurity, food waste, food related behaviours and cooking confidence of UK consumers following the COVID-19 lockdown.
Design/methodology/approach
Data were collected from 473 UK-based consumers (63% female) in March 2020. A cross-sectional online survey measured variables including food insecurity prevalence, self-reported food waste, food management behaviours, confidence and frequency of use of a range of cooking methods, type of food eaten (ultra-processed, semi-finished, unprocessed) and packaging type foods are purchased in.
Findings
39% of participants have experienced some food insecurity in the last 12 months. Being younger, having a greater BMI and living in a smaller household were associated with food insecurity. Green leaves, carrots, potatoes and sliced bread are the most wasted of purchased foods. Polenta, green leaves and white rice are the most wasted cooked foods. Food secure participants reported wasting a smaller percentage of purchased and cooked foods compared to food insecure participants. Overall, participants were most confident about boiling, microwaving and stir-frying and least confident with using a pressure cooker or sous vide. Food secure participants were more confident with boiling, stir-frying, grilling and roasting than insecure food participants.
Practical implications
This has implications for post lockdown policy, including food policies and guidance for public-facing communications.
Originality/value
We identified novel differences in self-report food waste behaviours and cooking confidence between the food secure and insecure consumers and observed demographics associated with food insecurity

Measurement of the polarisation of W bosons produced with large transverse momentum in pp collisions at sqrt(s) = 7 TeV with the ATLAS experiment
This paper describes an analysis of the angular distribution of W->enu and
W->munu decays, using data from pp collisions at sqrt(s) = 7 TeV recorded with
the ATLAS detector at the LHC in 2010, corresponding to an integrated
luminosity of about 35 pb^-1. Using the decay lepton transverse momentum and
the missing transverse energy, the W decay angular distribution projected onto
the transverse plane is obtained and analysed in terms of helicity fractions
f0, fL and fR over two ranges of W transverse momentum (ptw): 35 < ptw < 50 GeV
and ptw > 50 GeV. Good agreement is found with theoretical predictions. For ptw
> 50 GeV, the values of f0 and fL-fR, averaged over charge and lepton flavour,
are measured to be : f0 = 0.127 +/- 0.030 +/- 0.108 and fL-fR = 0.252 +/- 0.017
+/- 0.030, where the first uncertainties are statistical, and the second
include all systematic effects.Comment: 19 pages plus author list (34 pages total), 9 figures, 11 tables,
