A biodiversidade e os impactos ambientais na Mata da Cafurna, Município de Palmeira dos Índios, Alagoas

Palmeiras dos Índios, estado de Alagoas, abriga uma rica biodiversidade na aldeia Mata da Cafurna, além de cerca de 150 famílias indígenas do povo Xukuru-Kariri. O presente estudo possui importância ambiental, pois dará ênfase à fauna e flora pouco conhecida e apresentará as interferências antrópicas contribuindo para uma maior conscientização no uso sustentável dos recursos naturais. A proposta deste trabalho é investigar através de pesquisas na literatura, a diversidade biológica na Mata da Cafurna e os possíveis impactos ambientais causados por agricultores ou pessoas externas à aldeia. Compilando dados de trabalhos científicos realizados nos últimos dez anos, foi possível a produção de uma lista contendo 39 espécies de plantas, entre as mais conhecidas estão o murici (Byrsonima crassifolia), a jatobá (Hymenaea courbaril), a jurema (Acacia jurema), o barbatimão (Stryphnodendron coriaceum) e o juá (Ziziphus joazeiro). Dentre os vertebrados identificados destaca-se a paca (Cuniculus paca), o guará (Chrysocyon brachyurus), o tamanduá (Myrmecophaga tridactyla), e o veado (Mazama spp.). Essas espécies correspondem a um número certamente inferior à quantidade existente na aldeia, pois foram produzidos poucos trabalhos científicos da área estudada.Verificou-se que a fragmentação, o desmatamento para agricultura, o uso irracional dos recursos naturais e a caça de animais alteram a paisagem tornando-se assim uma ameaça para a biodiversidade

Crescimento e sobrevivência da tilápia chitralada submetida a diferentes fotoperíodos

The objective of this work was to assess the effect of photoperiod in the growth and survival of tilapia chitralada, Oreochromis niloticus, during and after the sexual reversion. The work was carried out in 2006 and 2007, and divided into two experiments. In the first experiment, post-larvae of 0.031±0.0058 g and 1.24±0.096 cm were used, at the density of 1.5 post-larva L-1. The post-larvae were submitted to the following photoperiods: 0, 8, 12, 16, 24 hours of light and 12.5 hours of natural light, during 28 days. The fishes were fed with 45% crude protein balanced food, containing androgen hormone, at 20% of the total biomass, divided into four meals. Sampling was done at the beginning and at the end of the experiment. In the second experiment, sex reverted fingerlings of 0.38±0.16 g and 2.81±0.40 cm were used. The experiment protocols were the same as in the former experiment, except for the stock density (0.33 fish L-1), food ratio (10% of the total biomass) and the experimental period (46 days). Sampling was done every fifteen days. The photoperiod interfered more intensively in the survival of the tilapia post-larvae, and the natural light was the recommended photoperiod during the sexual reversion. The best survival rate of the fingerlings occurred in the 0-hour light group; regarding fingerling growth, however, better results in bodyweight and length were found in the other photoperiod groups. It seems that the photoperiod responses to survival and growth are related to fish age.O objetivo deste trabalho foi avaliar o efeito do fotoperíodo no crescimento e sobrevivência da tilápia chitralada, Oreochromis niloticus, durante e após a fase de reversão sexual. O trabalho foi realizado em 2006 e 2007, em dois experimentos. No primeiro experimento, foram utilizadas pós-larvas de 0,031±0,0058 g e 1,24±0,096 cm à densidade de 1,5 pós-larva L-1. As pós-larvas foram submetidas aos fotoperíodos 0, 8, 12, 16, 24 horas de luz e a 12,5 horas de luz natural, durante 28 dias. Os animais foram alimentados com ração de 45% de proteína bruta, com hormônio andrógeno, na proporção de 20% da biomassa total, dividida em quatro refeições. As biometrias foram realizadas no início e no fim do experimento. No segundo experimento, foram utilizados alevinos de 0,38±0,16 g e 2,81±0,40 cm, revertidos para macho. O desenho experimental foi semelhante ao do primeiro experimento, exceto a densidade de estocagem (0,33 peixe L-1), a taxa de alimentação (10% da biomassa total) e o tempo de experimento (46 dias). Realizaram-se biometrias quinzenais. O fotoperíodo interferiu mais expressivamente na sobrevivência das pós-larvas da tilápia, e a luz natural foi a mais indicada durante a reversão sexual. A melhor sobrevivência dos alevinos ocorreu no grupo 0 hora de luz. Melhores crescimentos em pesos e comprimentos, porém, aconteceram nos demais fotoperíodos. Taxas de sobrevivência e de crescimento, em resposta a diferentes fotoperíodos, parecem estar relacionadas à idade do peixe

O objetivo desse estudo foi verificar o efeito do Remédio Emergencial sobre a ansiedade e o estresse de alunos do terceiro ano do ensino médio de uma escola estadual de referência do agreste de Pernambuco. Trata-se de estudo de intervenção duplo cego quantitativo. Os alunos preencheram o questionário sociodemográfico, Inventário de Ansiedade Traço-Estado (IDATE-A-T e A-E) e Lista de Sinais e Sintomas de Estresse (LSS). Posteriormente, foram divididos em dois grupos: floral ou placebo, distribuídos por conveniência conforme a classificação do IDATE-A-T. Após 21 dias, os alunos preencheram novos instrumentos (IDATE A-E e LSS). Não houve diferença entre os escores de ansiedade estado e de estresse antes e depois do uso do floral, embora a correlação entre os escores de IDATE-A-T e IDATE-A-E e LSS, após o uso do floral, tenham sido reduzidas. Dessa forma, concluímos que o Remédio Emergencial reduziu a influência do traço de ansiedade sobre a ansiedade e sobre os sinais e sintomas de estresse. Percebe-se a necessidade da prescrição individual dos florais, pois as particularidades são perdidas nas médias. Embora sejam necessários mais estudos sobre a temática, o Remédio Emergencial apresenta potencial para atuar de forma positiva sobre os estados de estresse e de ansiedade dessa faixa etária.El objetivo de este estudio fue verificar el efecto de la Medicina de Emergencia sobre la ansiedad y el estrés de estudiantes de tercer año de secundaria de una escuela estatal de referencia en la zona rural de Pernambuco. Este es un estudio de intervención cuantitativo doble ciego. Los estudiantes completaron el cuestionario sociodemográfico, Inventario de Ansiedad Estado-Rasgo (STAI-A-T y A-E) y Lista de Signos y Síntomas de Estrés (LSS). Posteriormente, se dividieron en dos grupos: floral o placebo, distribuidos por conveniencia según la clasificación STAI-A-T. Después de 21 días, los estudiantes completaron nuevos instrumentos (STAI A-E y LSS). No hubo diferencias entre las puntuaciones de ansiedad y estrés antes y después de usar la flor, aunque la correlación entre las puntuaciones STAI-A-T y STAI-A-E y LSS, después de usar la flor, se redujo. Por lo tanto, concluimos que el Remedio de Emergencia redujo la influencia del rasgo de ansiedad sobre la ansiedad y los signos y síntomas de estrés. La necesidad de una prescripción individual de remedios florales es clara, ya que las particularidades se pierden en los promedios. Aunque se necesitan más estudios sobre el tema, el Remedio de Emergencia tiene el potencial de actuar positivamente sobre los estados de estrés y ansiedad en este grupo de edad

Erythrina velutina Willd. alkaloids : piecing biosynthesis together from transcriptome analysis and metabolite profiling of seeds and leaves

Introduction: Natural products of pharmaceutical interest often do not reach the drug market due to the associated low yields and difficult extraction. Knowledge of biosynthetic pathways is a key element in the development of biotechnological strategies for plant specialized metabolite production. Erythrina species are mainly used as central nervous system depressants in folk medicine and are important sources of bioactive tetracyclic benzylisoquinoline alkaloids (BIAs), which can act on several pathology-related biological targets. Objectives: In this sense, in an unprecedented approach used with a non-model Fabaceae species grown in its unique arid natural habitat, a combined transcriptome and metabolome analyses (seeds and leaves) is presented. Methods: The Next Generation Sequencing-based transcriptome (de novo RNA sequencing) was carried out in a NextSeq 500 platform. Regarding metabolite profiling, the High-resolution Liquid Chromatography was coupled to DAD and a micrOTOF-QII mass spectrometer by using electrospray ionization (ESI) and Time of Flight (TOF) analyzer. The tandem MS/MS data were processed and analyzed through Molecular Networking approach. Results: This detailed macro and micromolecular approach applied to seeds and leaves of E. velutina revealed 42 alkaloids, several of them unique. Based on the combined evidence, 24 gene candidates were put together in a putative pathway leading to the singular alkaloid diversity of this species. Conclusion: Overall, these results could contribute by indicating potential biotechnological targets formodulation of erythrina alkaloids biosynthesis as well as improve molecular databases with omic data from a non-model medicinal plant, and reveal an interesting chemical diversity of Erythrina BIA harvested in Caatinga

Protocol Proposal For The Care Of The Person With Venous Ulcer

Objective: To propose a care protocol for the care of the person with a venous ulcer in highly complex services. Methods and results: This is a methodological study, in three stages: literature review, validation of content and validation in the clinical context. The literature review was carried out from June to August/2011, being the basis for the construction of the Protocol for Venous Ulcers. The content validation included 53 judges (44 nurses, 8 physicians and 1 physiotherapist) selected through the Lattes platform to evaluate the items of the protocol. Validation in the clinical context occurred at the University Hospital Onofre Lopes, in Natal/RN with four judges (nurses), who worked in pairs, evaluating 32 patients with venous ulcers. The protocol was validated with 15 categories: sociodemographic data; anamnesis; examinations; ulcer characteristics; care with the lesion and perilesional area; medicines used to treat the lesion; evaluation and treatment of pain; surgical treatment of chronic venous disease; recurrence prevention (clinical and educational strategies); reference; counter-reference; and quality of life. Conclusion: The validated protocol regarding content and clinical context was applicable. Its implementation is a viable measure that assists in the reorientation of the team in high complexity services, aiming at wound healing and restoration of the patient´s integral health.
