Associação do padrão de ingestão lípidica com a qualidade da dieta, resistência insulínica e homocisteinemia em adultos

Objectives: To evaluate the association between the consumption of different dietary fats with the quality of the diet, insulin resistance, and hyperhomocysteinemia in adults. Methods: Cross-sectional study conducted with 624 overweight subjects (73.7% females). Assessments of food intake (24h food recall and health eating index-HEI), anthropometry, and biochemical assays of fasting glucose, insulin (HOMA-IR and β calculus) and homocysteinemia were performed. Results: The low quality of diet was associated with the vegetable oil at 3rd quintile (≥1.5-2.0 servings) showed risk 2.9 times and cholesterol at quintiles 2nd, 3rd, and 4th was 2.0 times. HOMA-IR was higher at 5th quintile of saturated fat (≥10,7% - total caloric value) with risk of 60% and hyperhomocysteinemia the vegetable oil at 3rd quintile (>1.5-2.0 servings) with risk of 12.0 times and 5th (≥3.5 servings) 7.1 times. However, significance disappeared when adjusted for anthropometric variables. Conclusion: Dietary fats were associated with the harm diet quality, insulin resistance, and hyperhomocysteinemia. However, associations are dependant of demographic variables, dietetic, and nutritional state. © 2011 CELOM.

Perfil de resistência a antimicrobianos de Staphylococcus aureus isolados de granjas e frigoríficos de suínos

Staphylococcus aureus are involved in a wide range of clinical problems to swine industry as son in humans. Epidemiological researchs prove his potential to acquire resistantence to antibiotics. Nowadays, methicillin-resistant S. aureus (MRSA) are responsabilized for nosocomial infections and many studies are done because MRSA are spread to extra hospitalar enrivonment and frequentely isolated from domestic animals including pigs. The aim of this study was to determine the presence o S. aureus at swine farms and identify the mecA, icaA and icaD genes and the resistant proflife to antibiotics. Overal, 458 swabs were taked from five pigeris and two slautherhouses. All the samples were placed on Braid - Parker and blood agar follow by biochemical analyses. The suspect colonies were submitted to PCR to confirm the S. aureus species, by the detection of the coa gene, mecA to avaible meticillin-resistant as son to the virulence gens icaA and icaD that can determine slime production. Antibiogram were done to evaluate the response to 11 antibiotics. All pigeris and slautherhouse were positive and 81 (79%) samples were S. aureus positive including four isolates from pigs employeers. The mecA gene was not detected. The icaD gene was most frequent and 41% were positive to both genes. The antibiogram show a lot of samples penicillin and tetraciclin resistant. Most of the samples were multirestant.

Resistência de genótipos de eucalipto a ceratocystis spp

Eucalyptus is the most important plantation forest species in Brazil. Wilt and canker caused by Ceratocystis fimbriata on eucalyptus were first reported in 1998 in plantations of an E. grandis × E. urophylla hybrid in southern Bahia, Brazil. This work aimed at studying the reaction of different eucalyptus genotypes after inoculation with C. fimbriata isolates, in order to find a possible source of resistance. The study included four isolates of Ceratocystis collected from eucalyptus in different regions. One disc of fungal mycelium with 1-cm-diameter (from colonies growing for 10 days on malt extract agar medium-MEA) was inoculated on the stem of thus injured eucalyptus plants (six months old). A cotton wool moistened with sterile distilled water was wrapped with plastic film. Control plants were inoculated with discs of MEA without fungal colonies. The inoculated plants were kept in a greenhouse. Wilt symptoms were observed 90 days after inoculation. The seedlings were cut in the longitudinal direction of the stem in order to observe the colonization of fungus in the plant xylem. We tested twenty eucalyptus genotypes, but only five showed resistance to all isolates of Ceratocystis, belonging to different species of Eucalyptus: E. urophylla (C2 and C9), E. grandis (C3), E. saligna (C6 and C13) Most E. gramdis genotypes were more susceptible to all four fungal isolates. These results support future studies related to eucalyptus resistance to Ceratocystis.

Variabilidade espacial da resistência mecânica do solo à penetração e umidade do solo em área cultivada com cana-de-açúcar na região de Humaitá, Amazonas, Brasil

The mechanical resistance to penetration (RP) is an attribute indicator of compaction was influenced by soil moisture. The objective of this study was to evaluate the spatial variability of soil resistance to penetration and soil moisture on area under cultivation of sugar cane in the region of Humaitá, Amazonas, Brazil. We conducted a sampling grid of 70x70 m where points were scored at regular intervals of 10 m, a total of 64 points. Soil samples were collected at depths of 0.00 to 0.15 m, 0.15 to 0.30 I 0.30 to 0.45 m for determination of soil moisture and soil resistance to penetration in the field. After analysis of these data analyzes were descriptive statistics and geostatistics. We conclude that all the variables studied showed spatial dependence and range values were higher than stipulated by the sampling grid and the RP and soil moisture showed a spatial relationship where lower values of PR concentrated on smaller values of soil moisture.
