Manual and electroacupuncture for labour pain : study design of a longitudinal randomized controlled trial

Introduction. Results from previous studies on acupuncture for labour pain are contradictory and lack important information on methodology. However, studies indicate that acupuncture has a positive effect on women's experiences of labour pain. The aim of the present study was to evaluate the efficacy of two different acupuncture stimulations, manual or electrical stimulation, compared with standard care in the relief of labour pain as the primary outcome. This paper will present in-depth information on the design of the study, following the CONSORT and STRICTA recommendations. Methods. The study was designed as a randomized controlled trial based on western medical theories. Nulliparous women with normal pregnancies admitted to the delivery ward after a spontaneous onset of labour were randomly allocated into one of three groups: manual acupuncture, electroacupuncture, or standard care. Sample size calculation gave 101 women in each group, including a total of 303 women. A Visual Analogue Scale was used for assessing pain every 30 minutes for five hours and thereafter every hour until birth. Questionnaires were distributed before treatment, directly after the birth, and at one day and two months postpartum. Blood samples were collected before and after the first treatment. This trial is registered at ClinicalTrials.gov: NCT01197950.

What determines the use of capital budgeting methods? : Evidence from Swedish listed companies

Purpose: This paper aims to extend and contribute to prior research on the association between company characteristics and choice of capital budgeting methods (CBMs). Design/methodology/approach: A multivariate regression analysis on questionnaire data from 2005 and 2008 is used to study which factors determine the choice of CBMs in Swedish listed companies. Findings: Our results supported hypotheses that Swedish listed companies have become more sophisticated over the years (or at least less unsophisticated) which indicates a closing of the theory-practice gap; that companies with greater leverage used payback more often; and that companies with stricter debt targets and less management ownership employed accounting rate of return more frequent. Moreover, larger companies used CBMs more often. Originality/value: The paper contributes to prior research within this field by being the first Swedish study to examine the association between use of CBMs and as many as twelve independent variables, including changes over time, by using multivariate regression analysis. The results are compared to a US and a continental European study.

Can’t Afford the Manolos? Buy the Book!: Chick Lit & Contemporary Consumerism

At the airport, across from the magazines at Wal-Mart, and probably somewhere near the front of local bookstores — chick lit is everywhere. One would probably recognize it from a distance as a sea of shiny pink1, the small glossy paperbacks cheerfully beckoning from their carefully constructed display. Chick lit has exploded into the western2 market over the last decade, captivating millions of readers with their tales of young, urban professional women navigating the worlds of careers, relationships, and of course, shopping. By the end of the novel, each of these components is generally resolved in somewhat formulaic fashion

Produção de biomassa e composição química de adubos verdes cultivados no Vale do Ribeira

The contribution of green manure to soil improvement and crop production depends primarily on biomass production and its chemical composition, which vary depending on the species, region and growing season. The aim of this research was to evaluate the chemical composition of biomass produced by green manures in Vale do Ribeira, São Paulo, Brazil. In order to develop this research, was carried an experiment in Pariquera-Acu, in 2006/2007, in completely randomized blocks design with four treatments (three green manure and spontaneous vegetation) and five replications. At 30, 60, 90 and 120 after sowing samples were collected in 1m(2) of the shoots and determined fresh and dry, and chemical composition biomass. Sunhemp, pigeon pea and mucuna produced, in decreasing order, the largest quantities of biomass and were more efficient than the spontaneous vegetation. The biomass produced by green manure had higher quality than that produced by spontaneous vegetation. Sunhemp and pigeon pea have a higher proportion of dry matter in stems which have low N, high C/N and L/N ratio, variables indicating slow decomposition of residues. The analysis of dry matter partitioned to better indication of the chemical composition of the residues and the prevision of the availability of nutrients in the soil.

Spermathecae of the mangrove crab Ucides cordatus: a histological and histochemical view

Ucides cordatus is the most commercially, important mangrove crab in Brazil. In spite of its economic importance, there are few studies of its reproduction, in particular the female reproductive system. The present study describes the histology and histochemistry of the spermathecae of U. cordatus. Adult females were can lit monthly from July 2004 through June 2005, at Iguape, State of São Paulo. The crabs were anaesthetized, and their spermathecae removed and fixed in Davidson's fluid, following the histological routine for paraffin. The slides were stained with HE, xylidine Ponceau, PAS, alcian blue (pH 1.0 and 2.5), Sudan black B and picrosirius-haematoxylin. Histologically, the spermathecae possesses a capsule of conjunctive tissue, rich in collalgen fibres, which surrounds the secretory columnar epithelium. In the lumen, individual sperm packets are not observed; the spermatophores are intermixed with the seminal fluid and secretions of the spermathecae itself. A large proportion of the free spermatozoids and spermatophores are arranged in homogeneous masses in the proximal part of the spermathecae. The secretion produced by the columnar epithelium appears to promote the movement of the gametes to the fertilization chamber, in a ventral position, allowing fertilization of the oocytes. Histochemically, the secretion produced by the columnar epithelium was strongly positive for neutral polysaccharides, positive for acid polysaccharides, and weakly positive for proteins and lipids. Tills secretion forms a glycoprotein matrix which is associated with maintenance of the spermatophores, which can remain stored for long periods.

Flow-injection spectrophotometric determination of dipyrone in pharmaceutical formulations using ammonium molybdate as chromogenic reagent

A simple and rapid flow-injection spectrophotometric method is reported for the determination of dipyrone in pharmaceutical formulations. The method is based on the reaction of dipyrone with ammonium molybdate in acidic medium to produce blue molybdenum, which was detected spectrophotometrically at 620 nm. The analyte was determined in a single-line flow system. The calibration curve obtained was linear in the range of 5x10(-4) to 8x10(-3) mol L-1 for dipyrone concentration and the precision ( s r =1.7%) was satisfactory. The method proved to be selective and adequately sensitive. Application of the method to the analysis of pharmaceutical samples resulted in excellent accuracy; the percent mean recoveries were in the range 95.3%-101% and relative errors less than 5.0% for five pharmaceutical formulations were found.

Tempo de migração dos macrófagos em matrinxã, Brycon amazonicus, por meio da técnica de inoculação de leveduras Saccharomyces cerevisiae

Na aquicultura são utilizados análises da ativação e incremento da migração de macrófagos, com intuito de verificar a capacidade imunológica inespecífica dos peixes frente a um desafio. Neste sentido, o objetivo deste estudo foi determinar o tempo de migração de monócitos/macrófagos para a cavidade peritoneal em matrinxã, Brycon amazonicus, por meio da técnica de inoculação de leveduras Saccharomyces cerevisiae, e verificar as possíveis alterações dos parâmetros hematológicos após o estímulo. Foram utilizados 30 matrinxãs com peso médio de 101,55 ± 24,50 g e comprimento médio de 19,75 ± 1,72 cm. Os tempos de inoculação utilizados foram 2, 4, 8 e 12 horas, sendo utilizados 6 animais por tempo. Após os períodos de incubação (2, 4, 8 e 12 horas), os exemplares foram anestesiados e alíquotas de sangue foram coletadas por punção do vaso caudal, para a análise: número total de células, contagem diferencial e total dos leucócitos e contagem total de trombócitos, hematócrito, taxa de hemoglobina e índices hematimétricos (VCM, HCM e CHCM). Os resultados mostram que a capacidade fagocítica do macrófago não apresentou diferenças significativas entre os tempos experimentais. Com relação ao índice fagocítico, o tempo de 2 horas representa o tempo em que os macrófagos fagocitaram maior número de leveduras com diferenças significativas em relação aos outros tempos experimentais, indicando que este tempo (2 horas) de incubação foi suficiente para a migração e ativação máxima dos macrófagos da cavidade peritoneal, da espécie estudada. Os valores do número de eritrócitos apresentaram diferenças entre os tempos de incubação. Entretanto, os valores dos outros parâmetros hematológicos não apresentaram diferenças significativas.

Morfologia e avaliação do crescimento inicial de plântulas de Bactris gasipaes Kunth. (arecaceae) em diferentes substratos

Este trabalho teve por objetivos descrever a morfologia dos diásporos, as fases da germinação e determinar o substrato mais adequado para o crescimento inicial de plântulas de pupunha. Periodicamente, unidades representativas de cada fase de germinação foram retiradas para a descrição da seqüência dos eventos morfológicos. Os substratos usados para o crescimento inicial foram Plantmax HT, areia, terra (latossolo roxo) e outro com proporções iguais de terra, areia e esterco (TAE). Avaliou-se o crescimento inicial das plântulas aos 101 dias após o transplante, com base na sua altura, número de folhas, comprimento e largura das folhas. Observou-se que as sementes são albuminosas, com endosperma oleaginoso e de consistência relativamente dura. O embrião é lateral, periférico e relativamente indiferenciado, de forma cônica. A germinação inicia-se com o desenvolvimento de uma massa de células indiferenciadas na depressão micropilar. Posteriormente, esta massa de células torna-se cilíndrica, com a diferenciação dos primórdios caulinar e radicular. O primórdio caulinar é constituído por três bainhas envolvendo a primeira folha. Estas se abrem sucessivamente, permitindo a emergência da folha primária. Entre os substratos testados, de acordo com os parâmetros avaliados, os mais adequados para crescimento inicial de mudas de Bactris gasipaes Kunth foram o TAE e o Plantmax.

A intervenção estatal no domínio econômico privado através da nova lei de recuperação de empresas e falências (lei 11.101/05)

Analysis of the elements of the Constitutional Order of the letter 1988 politics, with emphasis in the principles of this, a study on the intervention of the State in the private initiative by means of the Law of Recovery of Companies and Bankruptcies (law 11.101/05). New enterprise vision is admitted, over all in the interdependence between economic and social factors. Study on the globalization and the interdependence of economic and legal sciences in the construction of a legal optics in the search for the economic and social development, with the recognition of the interference of the Economy in the Right and its uneven importance. Still, we delineate the state intervention in the economic scope, of company and in the judicial recovery, as well as the consequences of such intervention in the involved credits in the judicial recovery and patrimony of the debtor in recovery. For such task, the elements of the Judicial Recovery, its principles and adequacy of these to the related ones in the chapter had been analyzed that turns on the national economic Order, describing the formal procedure for concession of the benefit of the Judicial Recovery and the principles in existing them. The forms of intervention of the State in the private economy were not disrespected, relating its direct and indirect performance as half of preservation of interests writings in the constitutional scope as public interest and preservation of the National economic Order. The regulating agencies as of direct state intervention were half not disrespected of the study for the relevance of the subject. It is revised national bibliography with incursions in French, Portuguese and North American comparative jurisprudence. One contributes in the aspect of the paper of the Judiciary Power in the protection of the companies in crisis and the social and economic impacts, over all in relation to the rights of the worked ones, credit and enterprise

Efeitos do desfluorano, sevofluorano e isofluorano sobre variáveis respiratórias e hemogasométricas em cães

Com este estudo objetivou-se avaliar, comparativamente, os efeitos de três anestésicos inalatórios sobre variáveis respiratórias e hemogasométricas em cães. Para tal, utilizaram-se 30 cães sadios, adultos, machos e fêmeas evitando-se aquelas em estro ou em gestação. Os animais foram separados e protocolados em três grupos de 10 cães cada (G1, G2 e G3). Induziu-se a anestesia geral com administração intravenosa de propofol, na dose de 10±1,3 mg/kg. em seguida procedeu-se à intubação orotraqueal e anestesia geral inalatória pelo desfluorano (G1), sevofluorano (G2) e isofluorano (G3), diluídos em oxigênio a 100,00%, por meio de circuito anestésico tipo semi-fechado, dotado de vaporizadores calibrados para cada agente anestésico. As variáveis estudadas foram Freqüência Respiratória, CO2 ao Final da Expiração, Saturação de Oxihemoglobina, Volume Corrente, Volume Minuto, Pressão Parcial Arterial de O2, Pressão Parcial Arterial de CO2, Excesso de Bases e pH. A avaliação estatística destas variáveis foi realizada pela Análise de Perfil, sendo considerado o nível de significância de 5,00%. Os resultados obtidos permitiram concluir que o desfluorano deprime o sistema respiratório aumentando a pressão parcial arterial de CO2 e o CO2 ao final da expiração; e diminuindo a pressão parcial arterial de O2 e o volume minuto, quando comparado com os outros anestésicos em teste.

Potential microbiological contamination of effluents in poultry and swine abattoirs

Health risks in the effluents of seven swine abattoirs and of seven poultry abattoirs were evaluated with regard to environment degradation and to dissemination of pathogenic microorganisms during the rainy and dry seasons. Supply-water samples from affluents and effluents of the treatment systems at different sites within the abattoir processing system were analysed. Similarly, water samples from the three recipient sites (emission point, 100 m upstream, 100 m downstream) were also analysed. Temperature, free residual chlorine (FRC), total coliform bacteria, Escherichia coli, enterococci, identification and serotyping of salmonellae were assessed. Scalding is the most significant stage in the slaughtering chain (P<0.05) when temperature is taken into account. Temperatures Lit effluents and at the sampled sites in the water bodies accorded to state and federal legislation standards. Supply waters did not meet the standards for FRC and microbial count standards according to the Ministry of Health and within limits imposed by the Industrial and Sanitary Inspection Regulations for Animal Products. Feather plucking and evisceration in Poultry slaughter and the cleansing of carcasses and facilities in Poultry and swine slaughtering had the highest contamination impact. The three loci at the water bodies were above the microbiological standards for classes II and III sites, in conformity with Law 8468 of the state of São Paulo, Brazil and Conama. Salmonella was found at several sites during slaughter, at both types of abattoirs, including in the effluent treatment system. This showed that these sites were the dissemination sources of the microorganism.

Quantificação de macronutrientes no solo e em folhas de cana-de-açúcar em função de doses de resíduo da mineração de bauxita

The experiment was carried out in green house with the objective of evaluating the effect of the bauxite mining residue in the rates of macronutrients in sugarcane and soil. Containers of 10 L were used. They received the following rates of bauxite residue: 0; 28; 56; 84; 112 and 140 t ha(-1). The used culture was the sugarcane (SP92 4221). The incorporation of the bauxite residue in the soil provided an increase in the levels of the soil macronutrients, and only for sulphur levels above 83 t ha(-1), it was possible to provide reductions of this nutrient. For rates of determined macronutrients in the leaf, levels above 70, 5; 125; 101; 56 t ha (-1) diminished the rates of nitrogen, phosphorum, potassium and sulphur, respectively. However, for calcium and magnesium the use of the residue provided the reduction of leaf rates. The level of the bauxite residue which had the largest production of dry mass was 64 t ha(-1).
