The purpose of this study was to evaluate the agronomic performance of some Geneva® apple rootstocks on plant vigor control, annual yield and cumulative yield, cumulative yield efficiency and fruit weight of ‘Gala’ and ‘Fuji’ scions compared to the traditional apple rootstocks ‘M.9’ e ‘MM.111’, used in Brazil. All the Geneva® apple rootstocks were more efficient than MM.111 on vigor control and cumulative yield efficiency of ‘Gala’ and ‘Fuji’ in the Middle West of the state of Santa Catarina. All of them induced higher cumulative yield than the ‘M.9’, mainly for the ‘G.213’ and the ‘G.210’ for both varieties, and the ‘G.202’ for ‘Fuji’. All the Geneva® rootstocks had more cumulative yield efficiency than ‘MM.111’. The ‘G.213’ and ‘CG.22’ were more efficient than ‘M.9’ for ‘Gala’. For ‘Fuji’, all Geneva® rootstocks were more efficient than ‘M.9’, except for ‘CG.22’. Considering all characteristics evaluated, G.213 (dwarfing) and G.210 (semidwarfing) were the most promising rootstocks for both scion varieties. The rootstock G.202 was very promising to ‘Fuji’ as well. © 2015, Sociedade Brasileira de Fruticultura. All rights reserved.

Interdisciplinary Toxicology | Year: 2012
We evaluated the toxicity of hepatic, hematological, and oxidative effects of glyphosate-Roundup® on male and female albino Swiss mice. The animals were treated orally with either 50 or 500 mg/kg body weight of the herbicide, on a daily basis for a period of 15 days. Distilled water was used as control treatment. Samples of blood and hepatic tissue were collected at the end of the treatment. Hepatotoxicity was monitored by quantitative analysis of the serum enzymes ALT, AST, and ?-GT and renal toxicity by urea and creatinine. We also investigated liver tissues histopathologically. Alterations of hematological parameters were monitored by RBC, WBC, hemoglobin, hematocrit, MCV, MCH, and MCHC. TBARS (thiobarbituric acid reactive substances) and NPSH (non-protein thiols) were analyzed in the liver to assess oxidative damage. Significant increases in the levels of hepatic enzymes (ALT, AST, and ?-GT) were observed for both herbicide treatments, but no considerable differences were found by histological analysis. The hematological parameters showed significant alterations (500 mg/kg body weight) with reductions of RBC, hematocrit, and hemoglobin, together with a significant increase of MCV, in both sexes of mice. In males, there was an important increase in lipid peroxidation at both dosage levels, together with an NPSH decrease in the hepatic tissue, whereas in females significant changes in these parameters were observed only at the higher dose rate. The results of this study indicate that glyphosate-Roundup® can promote hematological and hepatic alterations, even at subacute exposure, which could be related to the induction of reactive oxygen species.

Ensuring good production in apple orchards depends on efficient pollination, which is directly related to pollen-stigma compatibility, blooming time coincidence, high production and good germination capacity of pollen. The aim of this study was to evaluate the efficiency of different apple genotypes as pollinizers of 'Daiane' cv. at the climate of Middle-west of the state of Santa Catarina, Brazil. Apple trees of 'Daiane' cv. were pollinated in the field with several apple selections from the Apple Breeding Program of Epagri - Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina. Right after pollination, the flowering clusters were protected with paper bags for 72h hours. It were considered the coincidence on blooming time, the climatic adaptation of the trees, the percentage of germination, the reaction to Gala Leaf Spot disease, as well as the fruit set and the number of seed per fruit induced by the pollinizers of this study. It was observed that the best pollinizers for 'Daiane' apple trees were the selections 140/76 and 140/228, respectively. Both selections are indicated to be used combined as pollinizers of 'Daiane'.

Gallates with eight or more carbon atoms in the lateral chain show potent anticancer activity against various cell lines. However, studies regarding the in vivo antimelanoma activity of tetradecyl gallate (C14) have not yet been reported. In this study an evaluation of the ability of C14 to inhibit metastasis, using lung metastases as a model, was carried out. The experimental mouse melanoma model was established by intravenous injection of metastatic B16F10 melanoma cells. The systemic toxicity of C14 was evaluated in vivo by monitoring the weight, survival, biochemical and hematological parameters, and through histological analysis. It was observed that C14 decreased lung metastasis in vivo by 80% and increased the survival rate of the animals without toxic effects. Additionally, C14 induced cytotoxic effects on B16F10 cells, inhibited the inter-cellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule 1 (VCAM-1) expression, and significantly decreased cell adhesion. These results reveal that C14 has potent antimetastatic ability and is a good candidate for further study as a potential therapeutic agent for tumor metastases. © 2012 Springer Science+Business Media, LLC.

The aim of this study was to evaluate the physical fitness and quality of life of elderly attending a University of the Third Age (UTA). The sample was composed of 189 elderly women and 50 elderly men, divided into three age ranges (60 to 64 years, 65-69 years and 70 or older). Physical fitness was evaluated by Senior Fitness Test and quality of life by WHOQOLOLD questionnaire. For intragroup and intergroup comparisons between different age ranges and gender was used analysis of variance (ANOVA), followed by Tukey post hoc test for multiple comparisons, with significance level of p<0.05. Results showed that there was no difference in BMI between gender in different age ranges of elderly from UTA (p>0.05). Nevertheless, elderly men of 65 years or more were with overweight and obesity, and elderly women only between 60 to 64 years. In the physical fitness, elderly man did not showed differences between age ranges and gender in most test (p>0.05). Were presented values below average in most physical fitness tests of elderly from UTA compare to American elderly in different age ranges and gender. The score of 66.16% showed that the samples of elderly were satisfied with the overall quality of life. In conclusion, physical fitness of elderly that attending a University of the Third Age are below average and the elderly are satisfied with the quality of life.
