Caracterización química del aceite de barú y su subproducto de la región noroeste de Minas Gerais, Brasil

This study investigated baru oil and partially defatted baru flour from the northwest region of Minas Gerais, Brazil. The physicochemical characterization of the oil was made by determining the fatty acid profile using gas chromatography, lutein, and α- and β- carotenes by means of high-performance liquid chromatography, and total carotenoids by spectrophotometry. The flour was analyzed for its chemical composition, fiber, and mineral contents. Baru oil presented excellent quality parameters and high contents in unsaturated fatty acids and carotenoids. The flour showed relevant levels of proteins, lipids, and dietary fiber, in addition to having representative mineral contents for food such as manganese, magnesium, and copper. Thus, baru oil and the by-product of its extraction offer a rich chemical composition, and their application may add nutritional value to foods in addition to reducing negative environmental impacts.En este estudio se investigó el aceite de barú y la harina de barú parcialmente desengrasada de la región noroeste de Minas Gerais, Brasil.

Variabilidade Do Desempenho No Line-drill Test Em Adolescentes Jogadores De Basquetebol

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)The practice of basketball during adolescence increases the body size and functional performance. Basketball involves short-time maximum effort for changes of direction, which use anaerobic metabolism and agility. Objective: To examine the variation in performance in the Line-drill Test in adolescent basketball players (n=59, age 9-15 years) in relation to the stage of somatic maturity (estimated age of peak growth velocity [PGV]) and the variation in body size. Methods: We considered chronological age, estimated time for the age of PGV by the maturity offset protocol, height and body mass measured by anthropometry, and performance in the Line Drill Test. Proportional allometric models were used to control the variation associated with the body size, chronological age, and maturity of inter-individual variation in the Line-drill Test. Results: We found a high negative linear relationship between performance in the Line-drill Test and chronological age (r=-0.64, 95% IC -0.77 - -0.46, p<0.01). The relationship between performance on the Line-drill Test and the time until the age of PGV proved to be non-linear, indicating slowdown in performance variation, approximately from the age of PGV and one year after the predicted PGV. The allometric models showed a negative relationship between body size and performance in the Line-drill Test. The amplitude of variance explained in the proportional allometric models ranged from 0.28 to 0.48. Negative exponents of small magnitude were observed for chronological age and the indicator of maturity being, however, significant and with reduced amplitude (-0.05 to -0.06) Conclusion: The use of allometric models to control the influence of body size can potentially help to understand the development of agility performances in adolescent basketball players. © 2016, Redprint Editora Ltda.

Concentrações sérica e hepática de cobre, ferro, molibdênio e zinco em ovinos e caprinos no estado da Paraíba. [Serum and liver copper, iron, molybdenum and zinc concentration in goats and sheep in the state of Paraíba, Brazil.]

ABSTRACT.This study aimed to determine Cu, Fe, Mo, and Zn liver and serum concentration in sheep and goats raised in the rangelands of the semiarid region of the state of Paraíba, Brazil, during the dry and rainy seasons, and to establish if Cu deficiency is primary or secondary to high ingestion of Mo or Fe. Cu, Zn, Mo and Fe concentrations were determined by atomic absorption spectrometry coupled to mass (ICP-Plasma) in 253 liver and serum samples randomly selected in a slaughterhouse. The mean serum concentrations of Cu in the goats and sheep were 11.82±3.28μmol/L and 10.97±3.61μmol/L respectively. The liver Cu concentrations were 160.37±11.77mg/kg in goats and 152.12±13.16mg/kg in sheep. The mean serum Fe concentrations were 16.38±4.51μmol/L in goats and 25.41±9.76μmol/L in sheep. The mean Fe concentrations in the liver were 189.37±6.51mg/kg in goats and 313.70±12.89mg/kg in sheep. The mean serum concentrations of Mo were 0.14±0.04μmol/L in goats and 0.29±0.06μmol/L in sheep. The mean Mo concentrations in the liver were 6.09±0.23mg/kg in goats and 6.22±0.15mg/kg in sheep. The mean serum Zn concentrations were 8.30±1.91μmol/L in goats and 8.63±2.22μmol/L in sheep. The mean Zn concentrations in the liver were 132.80±3.39mg/kg in goats and 130.70±2.99mg/kg in sheep. These results show low or marginal serum and liver concentrations of Cu and Zn, indicating that these minerals should be supplemented. The normal or even low concentrations of Mo and the high concentration of Fe suggest that Cu deficiency may be primary, due to low Cu ingestion, or secondary due to high Fe ingestion. © 2018 Colegio Brasileiro de Patologia Animal.

Cu, Zn, Mo, e Fe foram determinados por espectrometria de absorção atômica com plasma indutivamente acoplado (ICP-OES) em 253 amostras de fígado e soro selecionados aleatoriamente em um matadouro. As concentrações séricas de Cu nos caprinos e ovinos foram 11,82±3,28mmol/L e 10,97±3,61mmol/L, respectivamente. As concentrações de Cu no fígado foram de 160,37±11,77mg/kg em caprinos e 152,12±13,16mg/kg em ovinos. As concentrações séricas de Fe foram de 16,38±4,51mmol/L em caprinos e 25,41±9,76mmol/L em ovinos. As concentrações de Fe no fígado foram 189,37±6,51mg/kg em caprinos e 313.70±12,89mg/kg em ovinos. As concentrações séricas de Mo foram de 0,14±0,04mmol/L em caprinos e 0,29±0,06mmol/L em ovinos. As concentrações de Mo no fígado foram 6,09±0,23mg/kg em caprinos e 6,22±0,15mg/kg em ovinos. As concentrações séricas de Zn foram 8,30±1,91mmol/L em caprinos e 8,63±2,22mmol/L em ovinos. As concentrações de Zn no fígado foram 132,80±3,39mg/kg em cabras e 130,70±2,99mg/kg em ovelhas. Estes resultados mostram concentrações baixas ou marginais de Cu e Zn no soro e fígado indicando que estes minerais devem ser suplementados. As concentrações normais ou mesmo baixos de Mo e as altas concentrações de Fe sugerem que a deficiência de Cu pode ser primária, devido à baixa ingestão de Cu, ou secundária a alta ingestão de Fe

Low Expression of Human Histocompatibility Soluble Leukocyte Antigen-G (HLA-G5) in Invasive Cervical Cancer With and Without Metastasis, Associated With Papilloma Virus (HPV)

Human leukocyte antigen-G (HLA-G) is a non-classical major histocompatibility complex class Ib molecule that acts as a specific immunosuppressor. Some studies have demonstrated that human papillomavirus (HPV) seems to be involved in lower or absent HLA-G expression, particularly in cervical cancer. In this study, we performed a cross-sectional study, systematically comparing the qualitative expression of the HLA-G5 isoform in invasive cervical carcinoma (ICC), stratifying patients according to the presence [ICC with metastasis (ICCW)] and absence [ICC without metastasis (ICCWT)] of metastasis, correlating these findings with interference of HPV and demographic and clinical variables. Seventy-nine patients with a diagnosis of ICC were stratified into two groups: ICCWT (n=52 patients) and ICCW (n=27). Two biopsies were collected from each patient (one from the tumor lesion and one from a lymph node). Immunohistochemistry analyses were performed for the HLA-G5 isoform, for HPV detection, and virus typing. HLA-G5 isoform molecules were detected in 25 cases (31.6%), 17 (32.7%) without metastasis and 8 (29.6%) with metastasis. HPV was detected in the cervical lesions of 74 patients (93.7%), but low expression of the HLA-G5 isoform was observed in all HPV-related cases. These findings are important; however, additional studies are necessary to identify the influence of HPV with HLA-G5 isoform expression on invasive cervical malignancies.

Reforma do Estado e as políticas para a educação superior no Brasil nos anos 90 State Reforma and federal policies for higher education in Brazil in the 1990s

O presente artigo propõe-se a discutir as políticas educacionais implementadas no Brasil nos anos 90, do século XX, no que concerne à educação superior. Nessa ótica, parte da compreensão de que tais políticas são demarcadas por opções e interesses sociopolíticos articulados às mudanças no cenário contemporâneo, que se traduzem na apreensão das determinantes históricas que balizam o processo de reforma do Estado brasileiro. Essa lógica implica alterações no campo das políticas públicas, especialmente das políticas sociais, na medida em que estão em curso propostas e projetos que se configuram pela minimização do papel do Estado, marcado pela interpenetração das esferas pública e privada em detrimento da primeira. As políticas para a educação superior, nesse cenário, são analisadas indicando-se seus paradoxos e seus desdobramentos efetivos no que concerne aos processos de diversificação e diferenciação institucional, sistema de avaliação, expansão e privatização desse nível de ensino.<br>This article aims at discussing the federal policies for higher education implemented in Brazil in the 1990s. It assumes that such policies are based on socio-political choices and interests linked to the changes occurring in the contemporary Brazilian scene, changes that have deep historical roots, which emerge in the process of reformation of the Brazilian State. This situation implies alterations in the field of public policies, and more particularly in that of social policies, since the on-going official proposals and projects are characterized by a decrease of the role of State. The borders between public and private affairs have become increasingly blurred in a process detrimental to the former. The contradictions in the federal policies for higher education are analyzed here, as well as their results as for the following fields: institutional diversification and differentiation; assessment criteria, broadening and privatization of this level of education
