Anatomia foliar e análise de EDX de Costus spiralis (Jacq.) Roscoe de ambiente impactado e não impactado do litoral de São Paulo.

Several plants show morphological changes when exposed to environmental stress. We aimed to analyze comparative anatomy and EDX (energy dispersive x-ray detector) of Costus spiralis (Jacq.) Roscoe leaves from Jureia-Itatins Ecological Station (Peruibe, Sao Paulo), a preserved area, and Mogi River Valley (Cubatao, Sao Paulo) an affected area by pollution from the industrial complex of Cubatao. There were some significant differences in the leaves from the affected area, where they had a smaller abaxial hypoderm, larger size of adaxial hypoderm and larger central vascular core. There were damages in epicuticular wax deposition. The EDX analyses presented only differences in calcium and potassium concentration and presence of manganese in Cubatdo samples. Those leaves presented crystal deposition in the vascular core, probably because of the phosphogypsum residues from fertilizer industries.

Canto e fala: o espetáculo do poder da linguagem na tragédia grega

No presente estudo, destacamos como a estrutura da poesia trágica em partes cantadas e dialogadas resulta num grande espetáculo dominado pela palavra. Nos cantos corais e nos cantos de ator, os estados emocionais são marcados pelo viés da tradição do dialeto dórico. Nos diálogos, o ritmo próximo da fala quotidiana, em dialeto ático, acelera os acontecimentos em cena, põe em ação e movimenta o que Aristóteles depois vai chamar de “ação”. O resultado da mescla de tradição e novidade, de canto e fala, de dança e gestos, é um espetáculo contendo mito e “realidade”, poesia e retórica, entre outras dicotomias, em que o poder da linguagem é colocado em cena. Na tragédia, então, a palavra em todos os seus modos de expressão é o espetáculo a ser visto e ouvido. Assim, a tragédia grega insere-se numa longa tradição iniciada pela poesia oral homérica e anuncia o estabelecimento da filosofia.

Fatores associados ao metabolismo energetico na obesidade

Obesity is fundamentally a problem of energy balance that develops when the energy intake is greater than the total energy expenditure (TEE). TEE is composed by the sum of resting energy expenditure (REE), thermal effect of foods and thermal effect of physical activity. Many factors can affect energy expenditure and energy homeostasis. Historically, the energy expenditure has been measured by indirect calorimetry. However, more recently, the use of doubly labeled water has allowed the assessment of energy expenditure in a 24 hour period, which expanded the knowledge on energy metabolism. Factors such as gender, age, thyroid disorders, physical activity and body composition affect REE as already established in the literature. However, there has been speculation whether other factors, such as adipocytokines and diet composition, which might be involved in the genesis of obesity by decreasing the REE. So, this paper aims to review the factors that can alter the energy metabolism.

Spleenic Lymphoma and Hemoperitoneum in Jersey Bull: Clinical and Pathological Aspects

Lymphoma is the most prevalent neoplasia in dairy cattle. The etiology can be viral in animals affected by bovine leukemia virus (BLV) or be classified as primary. Lymphoma can affect several organs and according to the system involved, the clinical signs could manifest themselves in different ways. These tumors can be classified through macroscopic characteristics, histology and immunostaining. This classification can be used to predict prognosis and response to therapy. The aim of this case report was to immunostain and classify the tumor, for which anti-CD4, anti-CD8, anti-CD79 and anti-CD3 markers were used in addition to histopathological findings, in order to classify the tumor. The tumor was positive only for anti-CD3 marker, indicating that it is a tumor of young cells and, in association with histopathology and hematological data, it can be concluded that spleen neoplasia is lymphocytic lymphoma originated from a lymphocytic leukemia.

Qualidade das medidas antropométricas produzidas em unidades de atenção básica à saúde da região de Botucatu-SP, Brasil

The aim of this study was to evaluate the quality of weight measurements produced in Primary Health Care Centers in Botucatu and surroundings. 14 Health Care Centers were included, all of them located in four towns in the area of Botucatu (4,555; 5,656; 18,761 and 128,397 inhabitants). General conditions and scale calibration conditions found in those Health Care Centers were evaluated. In order to evaluate the weight accuracy obtained by the local team, 10 adult users of each Center were addressed by the rater during the service routine in order to get a new weight evaluation, immediately after the measurement made by the team. The statistic method applied for checking the weight measurement held in the Heath Care Center and the scales accuracy was the measurement error technique (MET). The results have showed that out of 19 scales, 6 of them overestimated the weight by 50 grams, 1 of them underestimated the weight by 200 grams and the others were accurate. Evaluated as a group, the result of the scale MET was 44.3g. Regarding the conformity of the measures obtained by the MET of the adults weighing in the Health Care Centers compared to the ones obtained by the researcher, the expected result was obtained in only one Center (< 100g). The results have showed data compromise, rather due to lack of health team training than due to the conditions of the equipment used for the measurement.
