The establishment of reference values is extremely important for successful diagnosis and treatament. Considering that in most species the serum chemistry profile is influenced by race, climate and management, we decided to determine the values of aspartate aminotransferase (AST), alanine aminotransferase (ALT), uric acid, creatinine, creatine kinase (CK), phosphatase alkaline (ALP), gamma-glutamyltransferase (GGT), total protein (TP) and albumin of Dekalb hens in the region of Araçatuba - SP. All samples were processed soon after harvesting in an automatic biochemical analyzer calibrated and monitored with control serum levels I and II. The following confidence intervals were obtained: 44-65,5 U / L (AST); 18,4-21,2 U / L (ALT), 2.1-2.5 mg / dL (uric acid); 1.7 to 5.7 U / L (CK); CI 1.2-2.2 mg / dL (creatinine), 1276-1506 U / L (FA); 18-23,4 U / L (GGT); 27.12 to 29 g / L (PT), from 11.4 to 12.16 g / L (albumin).

The broader knowledge about physical and mechanical properties of wood allows reliable timber structures design. Even little addressed in the literature, in several situations Poisson's ratios are required for the evaluation of stresses acting on structural elements. This study aimed to obtain values of Poisson's ratios (ν), plans Longitudinal-Radial (νLR) and Longitudinal-Tangential (νLT), for species Peroba Rosa (Aspidosperma polyneuron) and Jatobá (Hymenaea courbaril L.). For this purpose, forty samples Peroba Rosa and eight samples of Jatobá were prepared for testing in compression parallel to the grain, following the recommendations of ABNT NBR 7190 standard. The results of means confidence intervals, considered at the level of 5% significance, revealed that the Poisson's ratios νLR e νLT to Peroba Rosa are 0.27 and 0.42, respectively, and 0.25 and 0.43 to Jatobá.

Obesity is characterized by an excess of fat on the body and can results several problems on the individual health. As an epidemic of modern times, the prevalence started to increase at an accelerated rate from the 90's in worldwide. Data on the epidemic in Brazil and medium-sized cities are scarce, and the monitoring of obesity is essential for development public policy. So, the objective was to analyze the individual factors associated with obesity such as age, gender, education, marital status, economic class and level of physical activity and make a monitoring of obesity in adults in the city of Rio Claro - SP. To do this, the survey was conducted longitudinally, consists of two times at an interval of seven years. At first (2008) were interviewed 1588 adults in the city of Rio Claro distributed throughout the city. At the second phase (2014/2015) was conducted a new interview with the same subject in 1588. In 2008, personal information collected and applied some questionnaires with the physical activity level, food intake and quality of life. To assess obesity in adults was calculated the body mass index (BMI) proposed by the World Health Organization (WHO) from the high reported weight and height. For older people it used a specific BMI. The prevalence was used percentages and their respective confidence intervals of 95%. For the incidence, was calculated by the formula of cumulative incidence, both stratified by personal characteristics (gender, economic class, education, marital status and age). Thus it was observed that there was an increase in the prevalence of obesity in 2008 (19.0%), increasing to 26.7% in 2015. The cumulative incidence was 14.4% in the range of 7 years. As for the groups, we observed a significant difference between economic class and obesity being less prevalent among people of class D / E. Regarding marital status, it was observed that married / cohabiting have a higher prevalence. Therefore, we can conclude...

Objective: To identify associations between cytological criteria in fine needle aspiration (FNA) specimens and histological subtypes of lobular breast carcinoma (classical and other types). Study Design: FNA cytology and mastectomy specimens from 72 cases of invasive lobular breast carcinoma were consecutively retrieved from the files of the Amaral de Carvalho Hospital, Jaú-São Paulo, Brazil. All cases were reviewed regarding five cytological criteria: cellularity, cellular cohesion, presence of inflammation, nucleoli and nuclear atypia. The χ2 test or Fisher's exact tests with 95% confidence intervals (CI) were used. Results: The classical type showed lower initial cytological diagnosis of malignancy compared to the other variants (p = 0.017; odds ratio (OR) 0.26, 95% CI 0.89-0.80). Moderate/intense cellular cohesion (p = 0.011; OR 0.18, 95% CI 0.04-0.73) and mild atypia (p = 0.000; OR 16.15, 95% CI 3.20-81.48) were significantly associated with the classical type of lobular breast carcinoma, while the absence of inflammation (p = 0.082; OR 0.36, 95% CI 0.12-1.15) was marginally associated with the classical type. Conclusions: In cytology, the characterization of lobular carcinoma as malignant is difficult, especially the classical type. The association between cell cohesion and the classical type of lobular breast carcinoma may be one of the factors that complicate this diagnosis.
