Study of the length of the mouthparts of Africanized, Caucasian and Africanized/Caucasian honey bee crosses, and relationships between glossa sizeand food gathering behavior

Os comprimentos das peças que constituem o aparelho bucal, glossa, paraglossa, estipite, gálea, palpo labial, palpo maxilar, cardo, lorum, mento e pré-mento foram estudados a nível unidimensional em abelhas caucasianas, africanizadas e nos descendentes F1. Somente a paraglossa, estipite, gálea, palpo maxilar, mento e pré-mento mostraram ser diferentes entre esses 2 tipos de abelhas. Essas 6 variáveis foram estudadas nos descendentes F1, tendo sido utilizados 2 tipos de cruzamentos: rainhas caucasianas x machos africanizados (cruzamento 1) e rainhas africanizadas x machos caucasianos (cruzamento 2). Análises multidimensionais também foram realizadas, tendo sido obtidas as distâncias generalizadas de Mahalanobis (D2) entre os parentais e os descendentes F1. Tanto nas análises unidimensionais como nas multidimensionais houve aparente dominância das abelhas africanizadas, mas o número de genes não pôde ser conhecido porque só havia a geração F1 e não houve controle da heterozigosidade das 2 colônias parentais. Os cálculos dos coeficientes de correlações de Spearman mostraram que as abelhas com glossae mais longas coletaram mais xarope de açúcar e voaram mais lentamente da colônia para a fonte de alimento.

O setor pesqueiro em Portugal - relato de caso

Interviews were conducted with scientific researchers and process industries, bibliographic research and observational technical visits to collect information about the portuguese fishery sector. The relevance of this sector derives essentially from the fact that fish is a key component of food and responsible for large number of jobs within the Portuguese population. With the reduction in catches due to the decline in world's fish stocks the government has encouraged actions of ecological nature to promote the sector sustainability. Actually, the decline in the market expression facilitates the entry of stranger companies from others countries. Entrepreneurs must increase the productivity and provide quality assured products in order to achieve the export market.

O delineamento experimental foi o inteiramente casualizado com cinco tratamentos e quatro repetições de 20 aves. Os níveis de energia metabolizável fornecidos na ração na fase inicial variaram de 2.600 a 3.200 kcal/kg; na fase de crescimento de 2.700 a 3.300 kcal/kg; e na fase final de 2.800 a 3.400 kcal/kg. A proteína bruta e os demais nutrientes foram mantidos constantes em todas as rações, de acordo com recomendações do NRC (1994) para cada fase. A relação energia:proteína e o nível de energia metabolizável que melhoraram o desempenho e as características da carcaça de frangos de corte ISA Label machos criados em sistema semiconfinado em cada fase estudada foram 128 e 2.750; 147 e 2.850 e 172 e 3.100 kcal de EM/kg nas fases inicial, de crescimento e de terminação, respectivamente.

Energy balance for biodiesel production by the castor bean crop (Ricinus communis L.)

The castor bean crop (Ricinus communis L.) has acquired prestige due to industries interest in the oil quality and recently for new sources of energy demand. The experiment that served as basis for the data used in this study was conducted at the Lageado Experimental Farm, in Botucatu - SP, 2008. This study aimed to avaluate the crop viability through energy balance and energy efficiency since the implantation until biodiesel production using parameters of consumption in operational management for installation and maintenance of culture harvest and oil production. The soil management operations, sow and harvest consumed the total of 266.20 MJ ha(-1), gathering with the fertilizers, pesticides, fuels, lubricants, labor, seed and industrial processing totaled 56,808 MJ ha(-1) of energy inputs. The energy production was 72,814.00 MJ ha(-1). The industry still lacks studies thal would contribution data collection and more specific energy coefficients. The castor beans cultivation was considered efficient allowing again of 15983.44 MJ ha(-1) equivalent to about 415 liters of diesel oil.

Contato corporal entre adolescentes através da dança de salão na escola

The objective of this study was to identify the reaction and perception of adolescents in relation to body contact as well as emotional expressions through ballroom dancing. Forty-two adolescents from a public elementary school in the state of São Paulo participated in the study. Data gathering was conducted in groups by filming the ballroom dance class and applying a questionnaire about the experience. The dance experience was observed to provide greater body proximity and demonstration of affection, since part of the participants reported well-being, while others reported being embarrassed by dancing with a partner from the opposite sex. It was concluded that more dance activities related to biopsychosocial development need to be offered at school since ballroom dancing can help in interaction promoting body contact and thus facilitate in the process of interpersonal relations between adolescents.

Nonlinear methods of heart rate variability analysis in diabetes

Background: The autonomic dysfunction stands out among the complications associated to diabetes mellitus (DM) and may be evaluated through the heart rate variability (HRV), a noninvasive tool to investigate the autonomic nervous system that provides information of health impairments and may be analyzed by using linear and nonlinear methods. Several studies have shown that HRV measured in a linear form is altered in DM. Nevertheless, a few studies investigate the nonlinear behavior of HRV. Therefore, this study aims at gathering information regarding the autonomic changes in subjects with DM identified by nonlinear analysis of HRV.Methods: For that, searches were performed on Medline, SciELO, Lilacs and Cochrane databases using the crossing between the key-words: diabetic autonomic neuropathy, autonomic nervous system, diabetes mellitus and heart rate variability. As inclusion criteria, articles published on a period from 2000 to 2010 with DM type land type II population which assessed the autonomic nervous system by nonlinear indices HRV were considered.Results: The electronic search resulted in a total of 1873 references with the exclusion of 1623 titles and abstracts and from the 250 abstracts remaining, 8 studies were selected to the final analysis that completed the inclusion criteria.Conclusions: In general, the analysis showed that the nonlinear techniques of HRV allowed detecting autonomic changes in DM. The methods of nonlinear analysis are indicated as a possible tool to be used for early diagnosis and prognosis of autonomic dysfunction in DM.

Construct validity of a figure rating scale for Brazilian adolescents

Background: Figure rating scales were developed as a tool to determine body dissatisfaction in women, men, and children. However, it lacks in the literature the validation of the scale for body silhouettes previously adapted. We aimed to obtain evidence for construct validity of a figure rating scale for Brazilian adolescents.Methods: The study was carried out with adolescent students attending three public schools in an urban region of the municipality of Florianopolis in the State of Santa Catarina (SC). The sample comprised 232 10-19-year-old students, 106 of whom are boys and 126 girls, from the 5th series (i.e. year) of Primary School to the 3rd year of Secondary School. Data-gathering involved the application of an instrument containing 8 body figure drawings representing a range of children's and adolescents' body shapes, ranging from very slim (contour 1) to obese (contour 8). Weights and heights were also collected, and body mass index (BMI) was calculated later. BMI was analyzed as a continuous variable, using z-scores, and as a dichotomous categorical variable, representing a diagnosis of nutritional status (normal and overweight including obesity).Results: Results showed that both males and females with larger BMI z-scores chose larger body contours. Girls with higher BMI z-scores also show higher values of body image dissatisfaction.Conclusion: We provided the first evidence of validity for a figure rating scale for Brazilian adolescents.

Terapia de linguagem no espectro autístico: a interferência do ambiente terapêutico

OBJETIVO: Analisar o perfil funcional da comunicação de crianças e adolescentes com distúrbios do espectro autístico em dois ambientes de terapia de linguagem, que se diferenciam quanto ao aspecto físico. MÉTODOS: Participaram dez sujeitos com distúrbios do espectro autístico, seis do gênero masculino e quatro do gênero feminino, com idades entre 4 e 13 anos. Na coleta de dados, foram realizadas filmagens de oito sessões de terapia de linguagem individual com duração de 30 minutos, sendo quatro sessões em uma sala comum e quatro em uma sala com ambientação específica (sala NIC), intercaladamente, durante um mês. Para a análise dos dados foi empregado o Protocolo de Pragmática, e os resultados receberam tratamento estatístico. RESULTADOS: Verificou-se que não houve diferença significativa entre o perfil pragmático apresentado pelos dez sujeitos na sala comum e na sala NIC. CONCLUSÃO: O contexto físico aqui estudado não influenciou significativamente no perfil funcional da comunicação de indivíduos do espectro autístico, ainda que se tenha verificado tendências individuais apresentando melhor desempenho em uma sala ou em outra.

Acute neuromuscular manifestations in a patient associated with ingesting octopus (Octopus sp.)

Os autores relatam um quadro manifestado por sintomas neurológicos e musculares em uma mulher de 45 anos, que surgiu após o consumo da carne de polvo comum (Octopus sp.). A paciente apresentou intenso mal estar, parestesias em extremidades e área perioral, fraqueza muscular intensa e hipotensão arterial, seguidos de prurido importante e uma erupção eritêmato-descamativa disseminada tardia. Não foram observadas manifestações gastrintestinais ou febre, o que reduziu a probabilidade de uma intoxicação alimentar por conservação inadequada do molusco. A presença de sintomas neuro-musculares é sugestiva de ação de neurotoxinas, comprovadamente existentes em muitos gêneros de polvos e que podem ter sido ingeridas através do consumo das glândulas salivares ou acúmulo das toxinas na carne, por algum mecanismo ainda desconhecido. As toxinas dos polvos do gênero Octopus são pouco estudadas e julgamos esta comunicação importante por alertar para a possibilidade do envenenamento nos seres humanos que consomem carne de polvos e ainda sua diferenciação das intoxicações alimentares que ocorrem por conservação inadequada do animal.

Mononuclear phagocytes in the blood of turtles characterized by ultrastructural and cytochemical analyses and by phagocytic activity

Ultrastructural and cytochemical characteristics of mononuclear phagocyte cells in turtles are not well described in the literature, especially in Phrynops hilarii. Thus, the aim of this study was to evaluate these characteristics in the mononuclear phagocyte cells and their phagocytic activity in vitro using the turtle P. hilarii as an experimental animal model. The six turtles used in the study were observed in two seasons, spring and summer. Results showed that mononuclear phagocytes incubated only in diluted solution or with colloidal charcoal have cytoplasm phagolysosomes. The cells incubated with colloidal charcoal and further exposed to the cytochemical reaction for acid P-glycerophosphatase, showed cytoplasm phagolysosomes filled by charcoal particles being digested and some positively stained lysosomes. Acid P-glycerophosphatase positive reaction was present in lysosomes and inside the phagolysosomes, while acid cytidine 5-monophosphatase staining occurred in lysosome surroundings. A positive reaction for trimetaphosphatase was also found inside phagolysosomes. In conclusion, the presence of lysosomal enzymes like trimetaphosphatase and cytidine-5'-sodium monophosphate, in the circulating blood of P. hilarii indicate that mononuclear phagocytes participate in the phagocytic process by gathering many phagocytic cells and forming multinucleated giant cells, which probably have a role in the blood clearance process.
