Estádios larvais e ocorrência sazonal de imaturos de Psaroniocompsa incrustata (Lutz,1910)(Diptera:Smimuliidae) no Rio Pium, município de Nísia Floesta, RN

The larval instars, seasonal occurrence and environmental factors influence on Psaroniocompsa incrustata (Lutz, 1910) (Diptera: Simuliidae) immature were studied according to its physical and chemical aspects of breeding water. Four collects were made at vegetal substrate from margin, middle and floating on the Pium river, city of Nísia Floresta, state of Rio Grande do Norte, Brazil at dry and wet season. Some of larval characters were used to determinate the larval instars number like lateral length of cephalic capsulae, antennae and the distance among cephalic apodema, as well as pH, water temperature, width, depth, stream velocity, discharge and pluviometric precipitation were used for physical factors. Seven larval instars were determined for this P. incrustata community being the lateral length of cephalic capsulae as the best structure with this meaning propose. The seasonality immature abundance of this species were found in dry season and a positive correlation with pH, stream velocity and precipitation

A supervisão em contexto da reforma educativa angolana : um estudo da prática seminários e estágios pedagógicos dos estagiários na Escola de Formação de Professores de Benguela

O propósito do presente estudo de investigação visa compreender o papel do supervisor pedagógico no desempenho e desenvolvimento das competências pedagógicas dos professores em estágio na Formação Inicial de Professores no contexto das modificações implementadas pela reforma educativa. A sua elaboração surge no sentido da constatação, reflexão e compreensão, dos desfasamentos que se encontram entre as teorias propostas e os processos praticados num ambiente de adaptação às mudanças operadas no papel do supervisor e professores supervisionados. Este é um projecto de investigação avaliativa cujo aporte presta-se ao saber e avaliar e não resolver o problema. O estudo é de carácter descritivo e foi realizado, na escola de formação de professores de Benguela – IEFPB – com os professores acompanhantes e professores orientados em estágio no ano lectivo 2015. Optamos predominantemente por uma metodologia quantitativa por meio da aplicação de questionário por inquérito aos professores/supervisores e aos professores/supervisionados e para complementar usamos o método qualitativo por meio da aplicação de entrevistas semiestruturadas dirigidas ao director pedagógico e ao coordenador das práticas pedagógicas. No que tange à ortografia deste trabalho, optamos por não usar o novo acordo ortográfico da língua portuguesa, por não estar em vigor em Angola pelo que usamos ortografia antiga em português europeu.

Fatores que levam ao diagnóstico de câncer de mama em estágios avançados

O câncer da mama é o tipo de câncer que mais acomete as mulheres em todo o mundo. Grande parte dos casos é diagnosticado em estágios avançados da doença, quando a possibilidade do tratamento é limitada. Somente com a detecção precoce e o tratamento realizado no início do desenvolvimento do câncer de mama, há um bom aumento na sobrevida e consequentemente, a possibilidade de óbito diminui. O objetivo desse estudo foi identificar fatores que levam ao diagnóstico do câncer de mama em estágios avançados. Através da revisão, proporcionar subsídios para intervenções profissionais e propor estratégias para diminuir o índice de mulheres com altos índices de alterações mamográficas e descobertas de câncer de mama em estágios avançados. Pôde-se concluir que infelizmente o diagnóstico tardio do câncer de mama está prevalecendo em relação à detecção precoce. Apesar de toda divulgação e importância do tema, o que mais se observou durante a pesquisa bibliográfica foram os atrasos na descoberta do câncer de mama, gerando uma menor possibilidade de cura e menor sobrevida da população acometida. Encontramos como causadores dos atrasos no diagnóstico a demora entre a descoberta do nódulo e a primeira consulta com especialista, a falta de informações entre os paciente sobre a doença e o diagnóstico precoce e a falta de capacitação dos profissionais de saúde quanto à execução do exame clínico. A raça negra e a menor condição socioeconômica, também foram relatadas como motivos de atrasos tanto no diagnóstico quanto no tratamento da doença, quando comparadas àquelas de raça branca e de maior condição socioeconômica. Espera-se que, a partir dos resultados deste estudo, mais ações de saúde possam ser estabelecidas para a prevenção e o controle do câncer de mama na atenção primária e que os profissionais possam estar atentos ao diagnóstico precoce.

Síndrome de Rett: estudo retrospectivo e prospectivo de 28 pacientes

From November 1982 to May 1999, 28 children with Rett syndrome were followed-up for a medium period of 6 years and 2 months. Regression of developmental milestones started at the age between 5 and 20 months. Nineteen cases of typical Rett syndrome had uneventful pre and perinatal periods, loss of previously acquired purposeful hand skills, mental and motor regression and developed hand stereotypies; sixteen had head growth deceleration and 12 gait apraxia. Nine patients were atypical cases, 2 formes frustres, 2 congenital, 3 with early seizure onset, 1 preserved speech and 1 male. Epilepsy was present in 21 patients, predominantly partial seizures and the drug of choise was carbamazepine (15 patients). In the initial evaluation most patients were distributed on Stages II and III and on follow-up on Stages III and IV. Three children died.

Competição larval em Chrysomya megacephala (F.) (Diptera: Calliphoridae): efeitos de diferentes níveis de agregação larval sobre estimativas de peso, fecundidade e investimento reprodutivo

In insects that utilize patchy and ephemeral resources for feeding and egg laying, the outcome of larval competition for food resources depends on the amount of resources and the spatial distribution of immatures among patches of food. In the present study, the results of larval competition for food in Chrysomya megacephala, in traits such as female weight, fecundity and reproductive investment, were different in situations where the level of larval aggregation (proportion of competitors per amount of food) was the same, but with densities of competitors and amounts of food proportionally different. These results are indicative that the larval competition may depend both on the larval density and the amount of food, in different situations with the same proportion of larvae per gram of food.

TEORIA SINTÁTICA: DE UMA PERSPECTIVA DE -ISMOS PARA UMAPERSPECTIVA DE PROGRAMAS

This paper tries to show that the developments in linguistic sciences are better viewed as stages in a single research program, rather than different ideological -isms. The first part contains an overview of the structuralistas' beliefs about the universality and equivalence of human languages, and their search for syntactic universals. In the second part, we will see that the generative program, in its turn, tries to answer why language is a universal faculty in the human species and addresses questions about its form, its development and its use. In the second part, we will see that the paper gives a brief glimpse of the tentative answers the program has been giving to each of these issues.

Adaptação de protocolos invasivos e não invasivos para avaliações aeróbias e anaeróbias específicas ao basquetebol feminino

OBJECTIVE: To adapted the critical velocity (CV), RAST test and lactate minimum (LM) to evaluation of female basketball players. METHODS: Twelve well-trained female basketball players (19 ± 1yrs) were submitted to four intensities running (10 - 14 km/h) at shuttle exercise until exhaustion, applied on alternate days. The linear model 'velocity vs. 1/tlim' was adopted to determine the aerobic (CV) and anaerobic (CCA) parameters. The lactate minimum test consisted of two phases: 1) hiperlactatemia induction using the RAST test and 2) incremental test composed by five shuttle run (20-m) at 7, 8, 9, 10, and 12 km/h. Blood samples were collected at the end of each stage. RESULTS: The velocity (vLM) and blood lactate concentration at LM were obtained by two polynomial adjustments: lactate vs. intensity (LM1) and lactate vs. time (LM2). ANOVA one-way, Student t-test and Pearson correlation were used for statistical analysis. The CV was obtained at 10.3 ± 0.2 km/h and the CCA estimated at 73.0 ± 3.4 m. The RAST was capable to induce the hiperlactatemia and to determine the Pmax (3.6 ± 0.2 W/kg), Pmed (2.8 ± 0.1 W/kg), Pmin (2.3 ± 0.1 W/kg) and FI (30 ± 3%). The vLM1 and vLM2 were obtained, respectively, at 9.47 ±0.13 km/h and 9.8 ± 0.13 km/h, and CV was higher than vLM1. CONCLUSION: The results suggest that the non-invasive model can be used to determine the aerobic and anaerobic parameters. Furthermore, the LM test adapted to basketball using RAST and progressive phase was effective to evaluate female athletes considering the specificity of modality, with high success rates observed in polynomial adjustment 'lactate vs. time' (LM2).

Phenotypic variability in a family with x-linked adrenoleukodystrophy caused by the p.Trp132Ter mutation

X-linked adrenoleukodystrophy (X-ALD) is an inherited disease with clinical heterogeneity varying from presymptomatic individuals to rapidly progressive cerebral ALD forms. This disease is characterized by increased concentration of very long chain fatty acids (VLCFAs) in plasma and in adrenal, testicular and nervous tissues. Affected individuals can be classified in different clinical settings, according to phenotypic expression and age at onset of initial symptoms. Molecular defects in X-ALD individuals usually result from ABCD1 gene mutations. In the present report we describe clinical data and the ABCD1 gene study in two boys affected with the childhood cerebral form that presented with different symptomatic manifestations at diagnosis. In addition, their maternal grandfather had been diagnosed with Addison's disease indicating phenotypic variation for X-ALD within this family. The mutation p.Trp132Ter was identified in both male patients; additionally, three females, out of eleven family members, were found to be heterozygous after screening for this mutation. In the present report, the molecular analysis was especially important since one of the heterozygous females was in first stages of pregnancy. Therefore, depending on the fetus outcome, if male and p.Trp132Ter carrier, storage of the umbilical cord blood should be recommended as hematopoietic stem cell transplantation could be considered as an option for treatment in the future.

Are skeletally mature female rats a suitable model to study osteoporosis?

OBJECTIVE: To analyze if female Wistar rats at 56 weeks of age are a suitable model to study osteoporosis. MATERIALS AND METHODS: Female rats with 6 and 36 weeks of age (n = 8 per group) were kept over a 20-week period and fed a diet for mature rodents complete in terms of Ca, phosphorous, and vitamin D. Excised femurs were measured for bone mass using dual-energy x-ray absorptiometry, morphometry, and biomechanical properties. The following serum mar-kers of bone metabolism were analyzed: parathyroid hormone (PTH), osteocalcin (OC), osteoprotegerin (OPG), receptor activator of nuclear factor Κappa B ligand (RANKL), C-terminal peptides of type I collagen (CTX-I), total calcium, and alkaline phosphatase (ALP) activity. RESULTS: Rats at 56 weeks of age showed important bone metabolism differences when compared with the younger group, such as, highest diaphysis energy to failure, lowest levels of OC, CTX-I, and ALP, and elevated PTH, even with adequate dietary Ca. CONCLUSION: Rats at 26-week-old rats may be too young to study age-related bone loss, whereas the 56-week-old rats may be good models to represent the early stages of age-related changes in bone metabolism.
