Heritability for resistance to Puccinia psidii Winter rust in Eucalyptus grandis Hill ex Maiden in Southwestern Brazil

The climates of the central and southern regions of São Paulo state in Brazil favor pathogens such as Puccinia psidii Winter, which causes a common and severe disease in Eucalyptus plantations under 2 years old. We studied genetic parameters including genotype by environment interaction (G × E) of resistance to P. psidii rust in Eucalyptus grandis at nine sites in São Paulo State. Open-pollinated progeny from ten 'provenances' were established in a randomized complete block design; at individual sites there were from 134 to 160 progenies, from four to eight blocks, and five to six trees per plot. Significant provenance and progeny(provenance) differences were detected, as was G × E involving progeny(provenance). However, the G × E involved little if any rank changes, indicating that selection can be done efficiently at a single site, if the disease level is sufficient. The estimated coefficient of genetic variation among the progeny within provenances CVg was high and variable among the sites (ranging from 11 % to 36. 7 %), demonstrating different expression of genetic variability among the sites. The estimated heritability at the individual-tree level h2 and within a plot hw 2 ranged from low to intermediate (ranging from 0. 04 to 0. 46) and was high at the progeny-mean level hf 2 (ranging from 0. 30 to 0. 86). Our study shows good prospects of controlling this disease by selection among and within progenies in a single site. © 2012 Springer-Verlag Berlin Heidelberg.

Qualidade de vida em mulheres com ausência ou presença de terapia de reposição hormonal

The objective of this study was to evaluate the quality of life (QL) of a group of menopausal women in the presence or absence of hormone replacement therapy (HRT). It consists of a cross-sectional analytical study involving women from the School Health Center - Unity Village Farmers' and Town Railway on the city of Botucatu. Participants were divided into two related groups of studies: run HRT and do not realize. We used the SF 36 and QRS, and a questionnaire to characterize the study population. No differences were seen when comparing the groups with regard to age, age at menarche and menopause. It was observed that 92% were white women and who have studied up to primary education (p = 0.0209), and those who had a partner (p = 0.0055), were the most reported changes in QL. The most frequent comorbidities were hypertension and diabetes, which is significantly more important in women without HRT. The account of the lower of QL was expressed by 28% of the sample, and the population obtained in MRS score more negative (p, 0.05). The correlation of the eight components of the SF36 and the MRS, with the presence or absence of TRH showed no significant differences. The concept of quality of life and evaluation of it is subjective and individual. However they can notice changes in QL, evidenced by instruments. One can see that menopause is not necessarily accompanied by changes in QL, however, when expressed, tend to be perceived more negatively. Despite the lower level of social and low education and women interviewed have QL as good. There is a need for studies to improve a more real relationship between HRT and QL
